Description

Wheat germ processing running roller milling rolls

Technical Field

The invention relates to the technical field of wheat processing, in particular to a roller grinding mill for wheat germ processing.

Background

The embryo is the vital center of wheat and stores the essence of wheat, so that the embryo is praised by nutriologists as 'natural nutrition treasury of human' and 'source of human life'.

The extraction of wheat germ is mainly based on the characteristics of its grain shape, density and flakiness after rolling. Can be carried out in two stages of wheat cleaning and grinding. In the cleaning process of the wheat, 20 to 30 percent of germs fall off and are mixed in the cleaned leftovers; 70-80% of the germs are milled, and then part of the germs are mixed into flour and part of the germs are mixed into bran. Because the wheat germ mixed in the cleaned leftovers is not extruded and is not flaky, the wheat germ is not easy to extract. At present, the flaky wheat germ is extracted mainly in the milling process through a smooth roller mill and a grading sieve. In the prior art, the extraction rate of wheat germs is low, and the loss rate of germs is high.

For example, the wheat germ extraction device disclosed in the authorization notice number CN206542877U comprises a device body, a fourth filter screen and a fan. This wheat germ extraction element is through carrying out the milder wheat of wiping after to the humidification and handling, and the wheat receives the beating board of high-speed rotation and strikes, and the wheat produces collision and friction with the working face, also mutual collision and friction between the wheat for wheat germ and impurity after fully moistening are hit off, blow to first filter screen by the fan with wheat germ and impurity after hitting and handle the filtration, filter through the multiple filter equipment in the separator again, obtain pure wheat germ. However, this solution has several problems: because the wheat adopts the motor drive axle to rotate to drive and beat the board and rotate and realize acquireing the wheat germ of device body, but adopt and beat the board firstly directly to patting the wheat, the germ is difficult to directly drop, secondly beat the board and be the rigidity, beat the in-process because with the wheat effort the reason, produce great frictional resistance, make motor load grow, produce the damage, three produce the rupture very easily, and slew velocity is owing to frictional resistance's the reason, under the condition of same power, influence the rotational speed, thereby reduce the volume and the efficiency that the germ acquireed.

Of course, in order to make the wheat germ enter the filtering box 34 from the feeding opening 40 quickly, as shown in the prior art, a blower (not shown) is disposed on one side of the obtaining box 2, and blows the wheat grains, wheat germ and the like to the area of the first screen 36 of the feeding opening 40.

It should be noted that in the present embodiment, the electrical components, such as the stepping motor 12, the first motor 13, the heaters 17, 20, the water pump, the push rod motor 21, the second motor 32, the vibration motor 35, and the fan, are connected to the external power source, and then are logically controlled by a PLC controller, such as the siemens S-1200, or are integrated on the control panel surface through a connection inching switch for manual control, which is a well known prior art by those skilled in the art and will not be described herein again.

In the invention, when in work, firstly wheat is added into a moistening and steaming box 3 from a feed inlet 14, when the preset amount is reached, the wheat is stopped to be added, an end cover is covered, then a water pump 20 is opened, the water pump 20 conveys water to an atomizing spray head 16 through a water conveying pipe 18, then the water is atomized by the atomizing spray head 16 and is sprayed to the wheat in the moistening and steaming box 3, the wheat is moistened, the required water amount in the moistening and steaming box 3 is observed and controlled through a flow meter 19, when the set value is reached, the water pump 20 is closed, in the process, a first motor 13 is simultaneously opened to drive a stirring roller 15 to stir the wheat, the wheat in the moistening and steaming box 3 can be atomized by the atomizing spray head 16, a heater 17 is opened to heat when the wheat is moistened, the temperature in the moistening and steaming box 3 is increased, hot steam is generated in accordance with the temperature rise of the heater 17, when the preset temperature is reached, such as 65 ℃, the stirring is stopped, and then the stirring, for example, 20 minutes), so that moist hot steam exists in the moistening and steaming box 3, so that wheat can be sufficiently moistened, meanwhile, under the action of the hot steam, the wheat can absorb moisture, wheat grains after moisture absorption expand, the grain volume increases, the wheat grains soften and become fluffy, at the moment, after the moistening and steaming is finished, the water pump 20, the heater 17 and the like are turned off, the push rod motor 21 is controlled to work, the push rod is pulled back, and because the shape sealing plate 22 is provided with the blanking port 23, the moistened wheat falls onto the grid mesh plate 24 in the connecting box 4 from the blanking port 23 and then falls onto the first hollow roller 25 and the second hollow roller 26 through the grid through grooves 44 with the plurality of 1-3 cm in the bottom surface, so that blockage between the first hollow roller 25 and the second hollow roller 26 can be avoided, at the moment, the second motor 32 is turned on, and when the wheat passes through the pressing and binding mechanism, the second motor 32 drives the transmission wheel 28 to rotate the first gear 29, so that the second gear 30 rotates in the opposite direction, the first hollow roller 25 and the first hollow roller 25 rotate oppositely, when the moistened wheat falls between the first hollow roller 25 and the first hollow roller 25, due to the contra-rotation, the pricked moistened wheat can be pricked by the pricked parts 27 on the first hollow roller 25 and the first hollow roller 25, so that the wheat is pricked, the germ is knocked down by a knocking mechanism, the interval between the opposite pricked parts 27 on the first hollow roller 25 and the first hollow roller 25 is 1-2 mm, the moistened wheat is soft after moisture absorption, the moistened wheat can be pricked well, the moistened wheat falls into the obtaining box 2, the start, stop and rotation speed of the stepping motor 12 are controlled, the rotary rod 5 rotates to drive the first bat rod 6 to rotate, the first bat rod 6 drives the second bat rod 7 to rotate, and the pricked wheat is flapped flexibly, make wheat germ then beaten in filtering box 34, because the aperture of first sieve mesh hole 38 is less than the aperture of second sieve mesh hole 39, so great wheat grain can't fall into second sieve 37, can effectively accomplish like this and filter the collection to the wheat germ that beats down, and the germ is then can be quick through second sieve mesh hole 39 and falls into the bottom of filtering box 34, is collected at last.

According to the wheat germ filtering device, wheat is moistened firstly, so that wheat can absorb moisture, wheat grains after moisture absorption are expanded, the grain size is increased, the wheat grains are soft and fluffy, a threshing mechanism can easily knock down wheat germs, meanwhile, a pressing and binding mechanism is arranged, the wheat germs can be pricked conveniently, the threshing mechanism can knock down the wheat germs quickly and efficiently, and the wheat germs are filtered through a double-filtering net of the filter box body 34 to obtain pure wheat germs.

The invention realizes the wheat wetting by hot gas transpiration and then the pricking treatment of the wheat so as to facilitate the beating and knocking of the germ, and after the pricking treatment of the wheat, the wheat grains are subjected to the integrated treatment of the 'flexible' striking of the articulated type clapper rod rotating at high speed, thereby obtaining the wheat germ fast and efficiently. Compared with the prior art, the method can obtain a large amount of wheat germs efficiently in a short time.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
