Description

Rice mill

Technical field

The present invention relates to rice mill.

Background technology

In the past, the operation of the backing grain of rice many machines of seeking automation, laborsavingization had been developed.Have as representational, use mechanical force, in flowing water, utilize hydraulic pressure the grain of rice and the grain of rice machine of mutual friction mutually with the machine that water and the grain of rice stir.And, also have and chaff removed the clean rice of selling under the state of back.

As rice sheller in the past, the machinery (Japan Patent special be willing to flat 10-5989 number etc.) of structure is as shown in figure 42 arranged.Here the structure to rice sheller shown in Figure 42 describes.

As shown in figure 42, rice sheller 1 is provided with the roughly cylindrical vessel 2 that holds the grain of rice in inside.Again, in cylindrical vessel 2 roughly, sidewall is with formation such as wire netting and form the hole 3 that the grain of rice is passed through, and is provided with rotating vane 4 in inside.And, below cylindrical vessel 2 roughly, be provided with the drive unit 5 that drives rotating vane 4.Control device 6 accessory drives 5 and formation are controlled the rice operation.Also has rice sheller lid 7.

Now utilize Figure 43 that the action of rice sheller in the past is described.The user drops into the grain of rice 8 of ormal weight roughly in the cylindrical vessel 2, when rice sheller lid 7 being installed on rice sheller 1 back entry into service, utilizes control device 6 to make drive unit 5 actions.

Because rotating vane 4 rotates, the cylindrical vessel 2 interior grain of rices 7 stir to being contained in roughly when drive unit 5 actions.

Be subjected on the sidewall that pressing force that the grain of rice 8 that rotating vane stirs produces because of rotating vane 4 and centrifugal force is pressed against cylindrical vessel 2 roughly.

By the grain of rice 8 that is pressed on the sidewall since with constitute roughly that the hole 3 of the sidewall of cylindrical vessel 2 rubs mutually and the grain of rice 8 collides each other, just roll the chaff 9 on the surface of the grain of rice 8.And, the chaff 9 under rolling and be mingled in rubbish in the grain of rice 8 and small worm etc. 3 is discharged to the outside of cylindrical vessel 2 roughly from the hole.

Again, the grain of rice 8 is owing to continuously be urged on the sidewall of cylindrical vessel 2 roughly, so the grain of rice 8 that is crushed on the sidewall rises along sidewall because of rotating vane 4.The grain of rice that rises along sidewall is owing to impose on the rising composition of power of the grain of rice 8 and the balance of the deadweight of the grain of rice 8, thereby rises to the roughly specified altitude of cylindrical vessel 2.And when rising to the height of regulation, because that a side of the deadweight of the grain of rice 8 becomes is bigger than the rising composition of the power that puts on the grain of rice 8, so as shown in figure 17, the grain of rice 8 falls to the roughly bottom center of cylindrical vessel 2 roughly.

The circulation that the grain of rice 8 that falls repeatedly is crushed on because of rotating vane 4 on the sidewall of cylindrical vessel 2 roughly and rises, separates chaff 9, rubbish and small worm etc., falls to the roughly bottom center of cylindrical vessel 2 roughly along the sidewall of cylindrical vessel 2 roughly.And the grain of rice 8 is by finish rolling equably.Through behind the official hour, control device 6 stops and the end of turning round drive unit 5.

In the rice mill of such structure in the past and rice sheller, there is following problem.

The machine that uses mechanical force to stir the water and the grain of rice damages the grain of rice easily, and the water that is mixed with chaff can not be separated with the grain of rice as soon as possible.Therefore, the grain of rice absorbs the smelly water of chaff, and the rice after cooking becomes the smelly meal of band chaff, also has, and is contained in the fatty acid oxidation in the chaff and makes the smelly increase of insulation.

In flowing water, utilize hydraulic pressure with the grain of rice and the grain of rice mutual friction and essential a large amount of water mutually again.

For the clean rice of under the state of removing chaff, selling 2 kinds of manufacture methods are arranged again.The clean rice that makes water in manufacturing process is after washing, owing to circulate making under its dry status, so poor eating.Make the clean rice of the chaff that sticks with glue matter, system is very extensive and uses chaff also to be not easy operation, exists the problem that can not constitute single system.

Again, Figure 42 and rice sheller 1 shown in Figure 43 owing to being so that to remove chaff 9 be the machine that purpose is developed from the rice kibbled, are brute forces so rotating vane 4 puts on the power of the rice of kibbling.Therefore, when being used for removing the chaff 9 on rice surface when rice is dropped into rice sheller 1, the system of rice sheller 1 puts on the power on the rice, is undue powerful and can damage the starch monomer on rice surface for the chaff 9 of removing the rice surface.

Therefore, when cooking, cause the outflow of starch easily, will produce the rice that is burnt suiting one's taste of infringement rerum natura such as be clamminess and bring harmful effect.

Again, as shown in figure 43, the grain of rice 8 that rises along the sidewall of cylindrical vessel 2 roughly is owing to descend from the sidewall sections of cylindrical vessel 2 roughly, so situation about falling to the roughly bottom center of cylindrical vessel 2 is roughly also arranged not.

Again, the edge is the grain of rice 8 of the sidewall rising of cylindrical vessel 2 roughly, because only the deadweight because of the grain of rice 8 falls, so according to the input amount of the grain of rice 8 and the rotating speed of rotating vane 4 etc., at the composition one of the power that rises along sidewall during soon eventually greater than the deadweight of the grain of rice 8, as shown in figure 44, the grain of rice 8 keeps being crushed on the state on the sidewall of cylindrical vessel 2 roughly, can not rise or does not fall to the roughly bottom center of cylindrical vessel 2 roughly along sidewall.Therefore, the circulation of the grain of rice 8 can not be carried out effectively, and can produce the grain of rice 8 of undue damage starch monomer or produce the grain of rice 8 that chaff 9 is fully separated because of excessive friction.Therefore, also there is the irregular problem of husk rice.

In order to address these problems, be suggested the scheme of following rice mill: utilize effect because of rotating vane 4 to make the friction of the grain of rice grain of rice 8 that circulation time produced in cylindrical vessel 2 roughly between being harmonious, thereby roll the chaff 9 on the grain of rice 8 surfaces.

In the rice mill of this spline structure, owing to only utilize the grain of rice 8 mutual frictions to roll the chaff 9 on the grain of rice 8 surfaces, so can reduce because of making the grain of rice 8 excessive frictions too damage the problem of the grain of rice 8 starch monomers.

But, also same in this structure with above-mentioned rice sheller 1, as Figure 17 and shown in Figure 180, exist also that to produce husk rice irregular or expend the problem of more time for the backing of the grain of rice 8 because of the grain of rice 8 can not circulate effectively.

The summary of invention

The present invention makes for addressing the above problem, and its purpose is, provide the grain of rice is circulated efficiently and do not damage grain of rice starch monolithically with chaff from the surface isolation of the grain of rice and shorten the rice sheller of husk rice time.

Rice sheller of the present invention has: the container that holds the grain of rice; Be provided in the rotating vane in the container; Drive the drive unit of rotating vane; The control device of accessory drive; The grain of rice is enclosed in container cover in the container.Rotating vane makes has following ad hoc structure: on one side to the sidewall pushing on container top it is risen along container side wall or container cover in the grain of rice on one side, and container side wall or container cover make the next grain of rice that rises move to the substantial middle of cylindrical vessel roughly.As required, be provided with the sidewall of band peristome on the part of the side perimembranous of container, this peristome does not optionally make the grain of rice pass through.

Again, rice sheller of the present invention, utilize the centrifugal force make the rotating vane rotation and after the upper end that repeats to make the grain of rice rise to rotating vane, make its free-falling circulation.On the surface of rotating vane, form brush as required.

Again, the control device of rice sheller of the present invention makes the structure of the rotation speed change ground accessory drive that makes rotating vane in the husk rice operation.

Adopt structure of the present invention, the grain of rice is circulated efficiently and the starch that can not damage the grain of rice monolithically separates chaff and foreign matter from the grain of rice, or shorten the husk rice time.

The working of an invention form

Below, the present invention the 1st embodiment is described with reference to accompanying drawing.And, put on same-sign and omit explanation with the member of example same structure in the past.

＜embodiment 1 〉

Rice mill 10 shown in Figure 1 has roughly cylindrical vessel 11, and container 11 can hold the grain of rice.Again, the top of container 11 has and makes the grain of rice be enclosed within container cover 12 in the container 11.Again, rotating vane 4 is provided in the container 11, utilizes drive unit 5 to be rotated.

In said structure, utilize Fig. 2 that action is described.Drop in the container 11 grain of rice 8 of ormal weight and mounting cover 12.After being closed in the container 11 at mounting cover 12 and with the grain of rice 8, entry into service.

When beginning running, utilize control device 6 to make drive unit 5 actions and make rotating vane 4 rotations.And 4 pairs of grain of rices of rotating vane apply pressing force, and utilize the centrifugal force that produces on the grain of rice 8 towards container 11 sidewalls that is rotated in of rotating vane 4.At this moment, because the grain of rice 8 in the container 11 is shifted to the sidewall of container 11 in rapid succession because of centrifugal force, so the grain of rice 8 is along the roughly sidewall rising of cylindrical vessel 11.

Owing to dispose on the top of container 11 and cover 12, the grain of rice 8 that rises along the sidewall of container 11 and covers 12 collisions as Fig. 2 (a) shown in, shift to substantial middle portion along the inner face of R12 again.When the grain of rice 8 near near the substantial middle portions time, the centrifugal force that puts on the grain of rice 8 disappears, the power that forces on the grain of rice 8 only becomes gravity.Therefore, the grain of rice 8 utilize deadweight from the substantial middle clan of container 8 to the bottom.

So adopt present embodiment, lid 12 makes the grain of rice 8 change to the central portion of container 11 along the composition of the power of the sidewall rising of container 11.The grain of rice 8 not only rises along container 11 sidewalls, and moves along the lid 12 substantial middle portions to container 11, falls to the bottom from substantial middle portion again.Like this, the grain of rice 8 is roughly being circulated effectively in the cylindrical vessel 11.That is to say, owing to can produce circulating of the grain of rice effectively, make the grain of rice 8 produce friction each other and can improve the husk rice ability that the chaff 9 with the surface of the grain of rice 8 rolls.

Again, as shown in Figure 2, the top that also can be formed in container 11 forms covers a part of 12.Shown in Fig. 2 (c), also lid 12 can be constituted a part that forms container 11 sidewalls again.Also can on the sidewall of container 11, form the hole that optionally grain of rice 8 is passed through again.

＜embodiment 2 〉

The rice mill of present embodiment will cover 12 and form roughly spherical shape shown in Fig. 3 (a).Other structures are identical with the foregoing description 1.

Action in the said structure now is described.When making rotating vane 4 actions, utilize the pressing force and the centrifugal force of rotating vane 4 that the grain of rice 8 is risen along the sidewall of container 11.

At this moment, shown in Fig. 3 (b), form smooth occasion at lid 12, the connecting portion that might be created in container 11 and lid 12 is detained the situation of grain of rice 8a.To this, shown in Fig. 3 (a), form roughly spherical shape by covering 12, can not make the grain of rice 8 be trapped in container 11 and the connecting portion place of covering 12, can guide to the roughly bottom center of container 11 along all grain of rices 8 that sidewall rises reliably.

Again, in the stronger occasion of power of the grain of rice 8 that rises, in the structure of Fig. 3 (b), the grain of rice 8 collides with lid 12 and the grain of rice 8 is impacted, and in the structure of Fig. 3 (a), can reduce the impact that the grain of rice 8 and lid 12 collide.

Again, shown in Fig. 3 (a) and (b), part or all of rotating vane 4 forms parallel occasion with the sidewall of container 11, and the gap A of ormal weight will be arranged between the upper end of rotating vane 4 and container cover 12.

But, the less occasion of amount of the grain of rice 8 in dropping into container 11 is shown in Fig. 4 (b), when container cover 12 forms general horizontal direction, because the amount of the grain of rice 8 is few, so also produce can not be along covering the situation that 12 inner faces move even the grain of rice 8 can rise along the sidewall of container 11.On the other hand, shown in Fig. 4 (a), when lid 12 forms roughly spherical shape, owing to can reduce the connecting portion of container 11 and lid 12, so even in the less occasion of the grain of rice 8 amounts, the grain of rice 8 also can move along covering 12 inner faces.Therefore, also can make the grain of rice 8 to the roughly roughly bottom center circulation of cylindrical vessel 11 in the less occasion of the grain of rice 8 amounts.

In above-described present embodiment, all grain of rices 8 are roughly being circulated in the cylindrical vessel 11 reliably efficiently, and can reduce the impact that puts on the grain of rice 8.Even the grain of rice 8 is a small amount of, the grain of rice 8 is circulated reliably again.

＜embodiment 3 〉

The rice mill of present embodiment as shown in Figure 5, lid 12 has peristome B in substantial middle portion, and 12 the substantial middle portion of covering is configured in the place, below of container cover 12 ends.Other structures are identical with the foregoing description 1.

Now utilize Fig. 5 that action in the said structure is described, when rotating vane 4 actions, the grain of rice 8 moves along the sidewall of container 11 and the inner face of lid 12.At this moment because lid 12 central part is in the place, below of end, so the grain of rice 8 again along the substantial middle portion of container 11 to bottom cycle.Therefore, the grain of rice 8 can circulate efficiently.Again, have peristome B even cover 12 middle face, the grain of rice 8 can not jumped out to the outside from covering 12 peristome B yet.

Therefore, the grain of rice 8 is circulated efficiently in container 11, and, even drop into the grain of rice 8 in the container 11 and behind the mounting cover 12, do not unloading lower cover 12 and also can the new grain of rice 8 be dropped into from peristome B.

Again, also the top of container 11 can be formed resemble as shown in Figure 5 have the shape of peristome in substantial middle portion.

＜embodiment 4 〉

In the present embodiment, guide vane 13 shown in Figure 6 is formed on the direction with the inner face approximate vertical of container cover 12.Other structures are identical with the foregoing description 1.

Action in the said structure now is described.When rotating vane 4 action, the grain of rice 8 rises along the sidewall of container 11, and at this moment, as shown in Figure 7, the grain of rice 8 that comes of rising is shifted to substantial middle portion because of guide vane 13 follows into direction from the sidewall of cylindrical vessel 11 roughly.Therefore, owing to can make the grain of rice that rises 8 more efficient and move to the roughly bottom center of cylindrical vessel 11 roughly more reliably, so the grain of rice 8 is circulated.Again, guide vane 13 also can be provided with a plurality of.Guide vane 13 also can be formed at the top of container 11.

Again, guide vane 13 also can be to make the grain of rice 8 change mobile shape for lugs from the sidewall of container 11 like that to substantial middle portion.If make guide vane 13 by constituting, can only change the state of guide vane 13,, also can easily only change guide vane 13 even then guide vane 13 is when damaging with grain of rice collision with lid 12 or the part that separates of container 11 again.

＜embodiment 5 〉

In the present embodiment, as shown in Figure 8, guide vane 13 forms roughly curve shape.Other structures are identical with the foregoing description 1.

The action of said structure now is described.When rotating vane 4 action, the grain of rice 8 rises and, and at this moment, as shown in Figure 9, the grain of rice 8 that comes of rising moves to substantial middle portion from the sidewall of cylindrical vessel 11 roughly sleekly because of guide vane 13.

Therefore, the impulsive force that the grain of rice 8 and guide vane 13 collide can be reduced, and the durability of guide vane 13 can be improved.

＜embodiment 6 〉

In the present embodiment, as shown in figure 10, lid 12 has the peristome 14 that the grain of rice 8 is passed through.Other structures are identical with the foregoing description 5.

Now utilize Figure 11 that action in the said structure is described.When rotating vane 4 actions the grain of rice 8 being risen, the grain of rice 8 just collides with lid 12.At this moment because lid 12 has second peristome 14, so the grain of rice 8 because of mutual friction by backing, make to adhere to or be mingled in chaff 9 in the grain of rice 8 and rubbish and small worm etc. and jump out to the outside of cylindrical vessel 11 roughly simultaneously by the 2nd peristome 14.

Therefore, utilize the grain of rice 8 and the impulsive force that lid 12 collides, make chaff 9, rubbish and small worm etc. and the grain of rice 8 minutes, and can make chaff 9, rubbish and small worm etc. to the roughly outside discharge of cylindrical vessel 11.

Again, forming and cover 12 second peristome 14 and the grain of rice is passed through certainly, can be any shape.

＜embodiment 7 〉

In the present embodiment, as shown in figure 12, container cover 12 is for spherical shape roughly and have second peristome 14 that the grain of rice is passed through, and has chaff recoverer 15 around cylindrical vessel 11 roughly.Other structures are identical with the foregoing description 1.

In said structure, utilize Figure 12 that action is described.When the grain of rice 8 rises and when container cover 12 moves, chaff 9, rubbish and small worm etc. are separated with the grain of rice 8 and discharge to the outside of container 11 from covering 12.At this moment, because lid 12 forms roughly spherical shape, chaff 9, rubbish and small worm etc. jump out to the peripheral part of cylindrical vessel 11.Therefore, chaff 9, rubbish and small worm etc. can be again attached on the lids 12.

And owing to have chaff recoverer 15 at the peripheral part of container 11, chaff 9, rubbish and the small worm etc. that jump out are reclaimed by chaff recoverer 15.Therefore, can easily chaff 9, rubbish and small worm etc. be reclaimed by chaff recoverer 15.

＜embodiment 8 〉

In the present embodiment, as shown in figure 13, guide vane 13 has the 3rd peristome 16 that the grain of rice 8 is passed through.Other structures are identical with the foregoing description 1.

Now utilize Figure 14 that action in the said structure is described.When rotating vane 4 actions, the grain of rice 8 is directed to the substantial middle portion of container 11 along guide vane 13 from the sidewall of container 11, at this moment, owing on guide vane 13, be formed with the 3rd peristome 16 that the grain of rice 8 is passed through, so when the grain of rice 8 collides with guide vane 13 and when guide vane 13 moves, chaff 9, rubbish and small worm etc. separate with the grain of rice 8 by the 3rd peristome 16 of guide vane 13.Therefore, chaff 9, rubbish and small worm etc. are separated with the grain of rice 8.In the structure of present embodiment,, also can obtain in the effect described in

embodiment

6 and 7, so chaff 9, rubbish and small worm etc. are separated with the grain of rice 8 owing to have the peristome 14 that the grain of rice 8 is passed through as long as formation covers 12 again.

Again, if the grain of rice tool member at configuration brush class or soft works etc. on lid 12 inboard and the guide vane 13 replaces peristome 14 being set and peristome 16 being set on guide vane 13 on lid 12, then because grain of rice tool member can be removed chaff 9, rubbish and small worm etc. from the grain of rice 8 reliably, so can more improve the bright and clean state of the grain of rice after the husk rice.

＜embodiment 9 〉

In the present embodiment, as shown in figure 15, lid 12 has peristome B at central portion, and covers the below that 12 central portion is configured in the end.Again, lid 12 has the peristome 14 that the grain of rice 8 is passed through.Has the air-supply arrangement of air being sent in the container 11 17 on lid 12 top again.Other structures are identical with the foregoing description 1.

Action in said structure now is described.When rotating vane 4 action, the grain of rice 8 rises and moves along the lid 12 roughly bottom center to container 11, and at this moment, control device 6 drives air-supply arrangements 17, and air is sent to roughly in the cylindrical vessel 11.

In the time of in air is sent to container 11, the temperature that can control the grain of rice 8 that the grain of rice 8 mutual frictions that produce because of circulation time cause rises.

Again, owing to utilize air that air-supply arrangement 17 sends in container 11 to discharge to the outside of container 11, so chaff, rubbish and small worm etc. can be separated with the grain of rice 8 more efficiently and to the discharge of the outside of container 11 at peristome 14 from covering 12 peristome 14.Therefore, the temperature that can control the grain of rice 8 rises, can more efficiently chaff 9, rubbish and small worm etc. be separated with the grain of rice 8 again and discharges to the outside of cylindrical vessel 11 roughly.

＜embodiment 10 〉

The longitudinal section of the rice mill of present embodiment is shown in Figure 16.The rice mill of present embodiment has on the driving shaft 2 that is entrenched in drive unit 5 and as shown in figure 16 with the blade 4 of driving shaft 2 rotations.Blade 4 is made of with the junction surface 2 that husk rice portion 1 is connected with driving shaft 2 the husk rice portion 1 of 11 almost parallel ground settings of relative container as shown in Figure 2.

Action in the above structure now is described.By the grain of rice being dropped in the container 11 and operation (not shown), drive unit 5 begins rotation, makes driving shaft 2 and blade 4 rotations chimeric with driving shaft 2.

Utilize the rotation husk rice portion of blade 4, on one side relatively the side of container 11 keep certain intervals the grain of rice of contact to be applied the power of the tangential direction of rotation on one side, push the grain of rice and make it to the side of husk rice container 4 along rising on the side.Because the continuous generation of pressing force to the height that disposes husk rice portion 1, freely falls, returns the bottom surface of container 11 so the grain of rice that rises highlyer than the top of husk rice portion 1 loses power.

The grain of rice contacts or utilizes the mobile and stressed of air that blade 4 produces again with blade 4, move and repeat same action to the side.Should the circulation certain time, the mutual direction of the grain of rice is changed brokenly and friction mutually, the chaff on surface little by little is removed.Therefore, can damage the starch monomer on grain of rice surface hardly, the grain of rice after the processing separates with chaff easily, can alleviate the rice of washing by hand of washing and operate, even the surface that yet can make rice of cooking can not produce the grain of rice that is out of shape the good taste that is clamminess.

Again, among Figure 17, husk rice portion 1 is 2 places, but the number of husk rice portion 1 can at random determine.

＜embodiment 11 〉

Employed blade 4 is shown in Figure 18 in the present embodiment.In the present embodiment, be in the structure of embodiment 10, blade 4 is made of near the husk rice portion 1 of the almost parallel ground setting relative husk rice container side and the plectane junction surface 3a of concentric circles as shown in figure 18.

Action in the present embodiment is identical with the situation of embodiment 10.

Again, among Figure 18, husk rice portion 1 is 2 places, but the number of husk rice portion 1 can at random determine.

＜embodiment 12 〉

The structure of the blade 4 of the rice mill of present embodiment is shown in Figure 19.The rice mill of present embodiment is in the rice mill of embodiment 10, and the husk rice portion 1 of blade 4 sees the structure that makes to reverse with direction of rotation equidirectionally as shown in figure 19 from the top.Move identical with embodiment 10.

By the 1a of husk rice portion is reversed, the power that applies except the tangential direction to rotation also applies to radial direction, and the grain of rice is pressed on the side of container 11 more powerfully, and along rising on the side.

＜embodiment 34 〉

Present embodiment is described with reference to Fig. 2 (a).In the present embodiment, control device 6 accessory drives 5 make the rotation speed change of blade 4.

Just say so yet, adopt present embodiment, in the husk rice operation, control device 6 is not only with the husk rice rotational speed N shown in Figure 34 (b) ₁Certain rotating speed make rotating vane 4 rotation, shown in Fig. 2 (a), in the husk rice operation, can be provided with make blade 4 rotating speed with specific speed N ₁High rotational speed N ₂The operation that is rotated.

Therefore, owing to can get the aleurone (Japanese: stick with paste Fun Layer) 3 that constitutes the grain of rice 1 surface than quicker the rolling of conventional art, so shown in Fig. 2 (a), can be with the essential t of husk rice in the past ₁The husk rice activity time of time shortens into t ₂Time.

Again, in the husk rice operation, if make rotating vane 14 all the time with than husk rice rotational speed N ₁High rotational speed N ₂When being rotated,, and can damage starch monomer 2, also can damage the grain of rice 1 self sometimes certainly sometimes not only to the grain of rice 1 rolling aleurone 3.

＜embodiment 35 〉

In the present embodiment, as shown in figure 35, when the beginning of husk rice operation, make blade 4 with specific speed N ₁High rotational speed N ₂The operation that is rotated.Other structures are identical with embodiment 34.

Action in the present embodiment now is described.When the husk rice operation begins, as shown in figure 41,, so as shown in figure 35,, make rotating vane 4 with high rotational speed N if when the beginning of husk rice operation because the grain of rice 31 is coated by aleurone fully ₂During the operation that is rotated, can not can damage the only rolling aleurone 33 in starch monomer 32 ground.

Also say so,, can make the husk rice activity time with husk rice activity time t than embodiment 34 as shown in figure 35 by making the rotation speed change of rotating vane 4 ₂Shorter time t ₃The grain of rice 1 is carried out backing.

On the other hand, as shown in figure 36, when the husk rice operation begins, because the temperature of the temperature of container 11, blade 4 and drive unit 5 and the grain of rice 31 self is roughly room temperature T ₁, by when the husk rice operation begins, making blade 4 with high rotational speed N ₂The operation that is rotated, the variations in temperature of the grain of rice 31 is different with the variations in temperature (the characteristic A of Figure 36) of embodiment 34 occasions, produces the such variation of characteristic B of Figure 36.

That is to say that the temperature of the grain of rice 31 in the time of the husk rice operation being finished makes the end temp T than embodiment 34 ₂The T of lower temperature ₃Therefore, can carry out backing to the grain of rice 31, can reduce check and cracking because of the temperature rising generation of the grain of rice 31 with low temperature.

＜embodiment 36 〉

In the present embodiment, shown in Figure 37 (a) and Figure 37 (b), control device 6 is controlled to the rotating speed that makes blade 4 with drive unit 5 and gradually changes to becoming rotational speed N ₁And rotational speed N ₂Other structures are identical with the foregoing description 34.

The effect of present embodiment now is described.After the user dropped into containers 11 with the grain of rice 31 of ormal weight, rice mill 1 beginning husk rice operation, but when the grain of rice 31 drops into as shown in figure 38, existed the situation in the gap that the grain of rice 31 is sandwiched in rotating vane 4 and container 11.

If beginning husk rice operation, drive unit 5 desire to make blade 4 to rotate to regulation rotation N sharp under this state ₁And N ₂The time, be sandwiched in the rotation that the grain of rice 31 in the gap of blade 14 and cylindrical vessel 5 roughly will hinder blade 4.Therefore, might blade 4 do not rotate and can not carry out backing, also may cause and be fuming or damage because of drive unit 5 produces high load capacities to the grain of rice 1.And the grain of rice 31 that sandwiches 11 in blade 4 and container also can be chipping.

Therefore, shown in Figure 37 (a), little by little rise to the regulation rotational speed N by the rotating speed that makes blade 14 ₁And N ₂, can reduce making the grain of rice 31 be sandwiched in state between blade 4 and the container 11, can reduce the situation that the grain of rice 31 hinders blades 4 rotations.Its result can make the rotational speed N of blade 4 with regulation ₁And N ₂Be rotated, and prevent from drive unit 5 to produce rapid load, thereby can prevent being fuming and damaging of drive unit 5.Can also reduce hallrcuts on the grain of rice 31 or cracked.

Again, be not only the occasion of the rotating speed rising that makes blade 14,, also can as long as it is little by little changed even make the occasion of its decline.Shown in Figure 37 (b), also can make the rotating speed of blade 4 rise interimly or descend again.

Again, in the husk rice operation, even make blade 4 temporarily stop, again with the regulation rotational speed N ₁And N ₂The occasion of rotation if shown in Figure 37 (a) and (b), little by little rises rotating speed or descends just better.

＜embodiment 37 〉

In the present embodiment, formation control device 6 is controlled to drive unit 5 blade 4 is rotated to reverse directions sometimes to positive veer rotation sometimes.Other structures are identical with embodiment 34.

The effect of present embodiment now is described.Same with embodiment 36, when rice mill drops into the grain of rice 31, as shown in figure 38, exist the situation of the state in the gap that the grain of rice 31 is sandwiched in rotating vane 14 and cylindrical vessel 5 roughly.

At this moment, by making blade 14, can make the grain of rice shown in Figure 38 31 be sandwiched in the state in the crack between blade 14 and the container 11 and further reduce than the occasion of embodiment 36 to the rotation of positive veer and reverse directions (for example repeatedly repeat to positive veer rotation 1/2 rotation back to the action of reverse directions rotation 1/2 rotation etc.).

Therefore, can make the rotation of blade 14 more smooth and easy, can make blade 4 rotate to the regulation rotational speed N sharp ₁And N ₂And, can more reduce the load that when the husk rice operation begins, puts on the drive unit 5, the grain of rice 31 be can further reduce and hallrcuts or cracked situation produced.

Again, same with embodiment 36, even the occasion that is rotated again after blade 4 is temporarily stopped, if make blade 4 also better at the state that rotates to the regulation rotating speed to positive veer, reverse directions.

＜embodiment 38 〉

Finishing step shown in Figure 39 shown in the enlarged drawing of Figure 40, is to remove that aleurone 33 after rolling becomes chaff 9 and attached to the grain of rice 31 lip-deep operations.In this finishing step, as shown in figure 39, control device 6 is controlled to drive unit 5 and makes blade 4 with specific speed N ₁More slow-revving Seiko adds rotational speed N ₃The state that is rotated.Other structures are identical with the foregoing description 34.

The effect of present embodiment now is described.Though by making blade 4 with greater than N ₁Rotating speed rotation, by the aleurone 33 of the grain of rice 31 rolling coating grain of rices 31, but aleurone 33 becomes chaff, its part becomes the grain of rice 31 lip-deep states that are attached to as shown in figure 40.Therefore, generation can not make the situation that chaff 9 separates from the grain of rice 31 fully.

Therefore, make with specific speed N ₁More slow-revving fine finishining rotational speed N ₃The finishing step that blade 4 is rotated carries out in the husk rice operation or after the husk rice operation.By this finishing step, because blade 4 is with slow-revving N ₃Be rotated, so remove and only will be attached to the grain of rice 1 lip-deep chaff 9 on surface that can the rolling grain of rice 31.
