Description
Technical field
The invention belongs to foodstuff processing technology apparatus field, be specifically related to grain medium husk rice technical equipment, particularly the flexible rice mill of a kind of sand ball and a kind of grain medium husk rice method.
Background technology
As existing grain husk rice technology, mainly contain and cut Mill technique, extruding Mill technique and cut extruding associating Mill technique.In grain (comprising paddy, wheat, corn, coarse cereals etc.) husk rice enterprise, conventional rice milling unit, by Mill technique classification, mainly contains abrasive type rice whitening machine, iron roll rice polisher, sand roller iron roll combined rice mill; Arrange classification by roller, mainly contain horizontal rice whitening machine and vertical rice whitening machine; Divide by the quantity of roller in rice mill, mainly contain single roller rice mill, double roll rice polisher and multiple roll rice mill.Grind the distribution of muscle and mill groove by roller surface, be mainly divided into continuous muscle and segmentation muscle, directly muscle and spiral bar, succeeding vat and a fault trough etc.At present, will there is the problem of three aspects in grain husk rice owner both domestic and external.First is that the direct contact surface of roller and grain grain is long-pending less.No matter the roller of rice mill is sand roller or iron roll, and grain grain and roller direct contact surface amass and be less than 2% of contact area between grain grain.Second is that the pressure of husk rice indoor is larger.Because the direct contact surface of grain grain and roller amasss limited, by increasing the method for the pressure of husk rice indoor, the frictional force between grain grain can only be increased, improves husk rice effect.But husk rice chamber pressure increases, broken rice rate increase, rice milling yield reduction will be made.In addition, along with husk rice room pressure increases, the energy consumption of rice mill will increase.3rd is that roller rotating speed is very fast.Amassing with grain grain direct contact surface to increase in the roller unit interval, usually adopting the method improving roller rotating speed to realize.No matter be abrasive type rice whitening machine or iron roll rice polisher, the rotating speed of roller is usually between 800r/min ~ 1500r/min.The rotating speed reducing roller can make broken rice rate and energy consumption significantly reduce, but husk rice effect also can be made to decline, and can not complete the process goal of husk rice.In order to increase rice milling yield, reduce broken rice rate and reduce husk rice energy consumption, many engineers and technicians and scientific worker have done a lot of research and development work.
Chinese Patent Application No. is that " a kind of rice mill " of CN201310352566 relates to a kind of rice mill, comprise charging control part dress and whitening chamber portion dress, charging control part dress comprises charging adjustment doors, whitening chamber portion dress comprises sand roller, sand roller comprises core and iron core, and iron core is positioned at sand core internal, removably connects between core and iron core, core is divided into three parts, i.e. the first core section, the second core section and the 3rd core section; Every section of core adopts identical structure, that is: core body, and be respectively equipped with forward flange and rear flange at core body two ends, forward flange and rear flange are bolted, and forward flange and rear flange are equipped with keyway.Sand roller is divided into three parts by the present invention, and the first core section adopts deep spiral groove to ensure conveying output, and the second core section adopts moderate spirality groove to ensure milling efficiency, and the 3rd core section adopts the oblique straight trough of multiple tracks to control mill precision and go out a meter output; Core and iron core make separately, are then assembled together by screw rod and nut, therefore when after core wearing and tearing, only need change outside core.
This patented technology improves the structure of sand roller and connects combination, but to increase mill area, reduce roller rotating speed, reduce husk rice chamber pressure and do not propose neodoxy.

1. ingredient station
The mass ratio of grain (comprising brown rice, wheat, corn, coarse cereals etc.) and sand ball is between 1 ~ 10; The diameter of sand ball is between 5 ~ 25mm; Adopt continous batching mode, the sand ball in the grain in grain storehouse and sand ball storage warehouse is prepared burden.
2. the flexible husk rice workshop section of sand ball
The mixture of grain and sand ball enters the charging aperture of the flexible rice mill of sand ball through conveying equipment, as shown in Figure 2.The compound of grain and sand ball, under the mechanical force acting in conjunction of gravity and the flexible rice mill blade of sand ball, completes flexible rice milling process.The compound completing flexible rice milling process through the flexible rice mill of sand ball is discharged from the flexible rice mill discharged orifice of sand ball, enters Xia Dao workshop section.The chaff produced in the flexible rice milling process of sand ball, from the sucking-off of sand ball flexible rice mill row chaff mouth, through row's chaff pipe, enters chaff separator.In addition, from the chaff also row's of remittance chaff pipe of rice mill discharged orifice sucking-off, chaff separator is entered.
3. grain and sand ball compound classification workshop section
When grain is after 2 ~ 10 flexible husk rices, the compound of grain and sand ball enters vibration separation screen, utilize the acting in conjunction of the vibration of vibration separation screen and the size in sieve plate hole and suction chaff wind net, compound classification is become finished product (grain), sand ball and chaff.Wherein finished product through the classification of finished product collator, selected after packing and storing.Sand ball warp conveying equipment, makes sand ball return sand ball storage warehouse, then recycles.Chaff, through inhaling chaff wind net, is focused on chaff separator by chaff, collects, packs, stores.
The beneficial effect that the present invention has is:
1. increase the area of directly milling of grain.By being mixed into sand ball in proportion in grain, increasing nearly 100 times than the sand roller of existing rice mill or iron roll area of directly milling, being conducive to milling of grain grain top layer chaff skin and coming off.In addition, only the direct contact surface of diamond dust inner cylindrical surface and grain grain amasss the area of milling just being greater than original rice-milling roller or iron roll.
2. adopt the flexible husk rice of sand ball than using sand roller to cut husk rice or using the pressure of iron roll extruding husk rice little.Because the pressure of husk rice indoor reduces, the mechanical force that grain grain bears and internal stress also will reduce, and thus be conducive to reducing broken rice rate, also be conducive to increasing head rice yield and rice milling yield.
3. it adopting the flexible husk rice of sand ball, and sand roller cuts husk rice or iron roll extrudes compared with husk rice, and the rotating speed of roller can reduce greatly, and except the pressure of reduction husk rice room, the power of rice mill also can reduce, and is conducive to saving energy and reduce the cost.
