In the figure, 1-a hopper, 2-a grinding body, 3-a rotor pump, 4-a discharge pipeline, 5-a short-circuit valve, 6-a return pipeline and 7-a regulating valve.
Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
With reference to fig. 1, the soybean grinding in the prior art, whether dry grinding or wet grinding, basically consists of two steps of coarse grinding and fine grinding, and the soybean grinding is completed by at least two devices, which is high in cost and large in maintenance work. Referring to fig. 2, in an embodiment, the present invention discloses a soybean grinding apparatus, which specifically includes a grinding body 2 for grinding, a return pipeline 6, and a discharge pipeline 4, wherein one end of the return pipeline 6 and one end of the discharge pipeline 4 are connected in parallel to the grinding body 2, the other end of the return pipeline 6 is communicated to the grinding body 2 again, and the other end of the discharge pipeline 4 is a discharge end. In this scheme, because there is the design of return line 6, can flow back the soybean milk again and grind in grinding body 2 repeatedly, so can replace current thick and thin twice and grind mode and equipment, reduced the input of equipment, also reduced the maintenance of equipment simultaneously, improve production efficiency, reduction in production cost. In addition, because the soybean milk at the grinding outlet has extremely high kinetic energy, the soybean milk is easy to generate a large amount of bubbles, and the newly-added return pipeline 6 can release the kinetic energy pressure of the soybean milk, so that the generation of a large amount of bubbles is avoided, and the gas content in the soybean milk is reduced.
Preferably, the grinding body 2 comprises a feeding hole and a discharging hole, a hopper 1 is arranged at the feeding hole, one end of the return pipeline 6 and one end of the discharging pipeline 4 are connected in parallel to the discharging hole of the grinding body 2, and the other end of the return pipeline 6 is communicated to the feeding hole of the grinding body 2. I.e. the soymilk from the milling body 2, part of the soymilk is discharged along the discharge pipe 4, while the rest flows to the feed inlet via the return pipe 6 and returns to the milling body 2 again.
Preferably, the return line 6 is provided with an adjusting valve 7, the adjusting valve 7 can be used for adjusting the return flow in the return line 6, and the discharge amount of the final discharge line 4 can be adjusted by adjusting the return flow because the material flow at the outlet of the grinding body 2 is constant. When the amount of reflux is increased, the corresponding amount of discharge is relatively small, and when the amount of reflux is decreased, the corresponding amount of discharge is increased.
Preferably, a rotor pump 3 is arranged on the discharge pipeline 4. The ground soybean milk can be transferred to a next process, such as a separation process, by the rotor pump 3.
Preferably, the discharge pipeline is further provided with a short-circuit valve 5, and two ends of the short-circuit valve 5 are connected with two ends of the rotor pump 3 in parallel. The mill body 2 may preferably be a colloid mill, suitable for food production.
In addition, on the basis of the equipment, the invention also discloses a method for grinding soybeans by using the soybean grinding device, which specifically comprises the following steps:
s1, pre-adjusting the water inflow and the bean inflow according to the specific soybean milk discharge amount in unit time according to the production requirement to maintain the dynamic balance of continuous grinding production, wherein the water is heated to 70-80 ℃, preferably to 75 ℃, the ground soybeans are at the temperature of 75-85 ℃, preferably 80 ℃, and the soybeans are peeled, and the bean inflow is adjusted to 8-12%, preferably 10% of the water inflow;
s2, starting the soybean grinding device, adjusting the grinding gap and grinding the soybeans, namely adjusting the gap and the fineness of the soybean milk according to actual requirements and directly determining the maximum fineness of the soybean milk;
s3, adjusting the backflow amount, keeping the feeding liquid level of the soybean grinding device unchanged to block air from entering, in order to prevent the generation of a large amount of bubbles due to the large gas content in the soybean milk, always keeping the feeding liquid level unchanged to block the mixing of a large amount of air into the soybean milk to form bubbles, adjusting the backflow amount, namely adjusting the discharge amount of the soybean milk, wherein the backflow amount can be 3-15 times of the discharge amount, the discharge amount cannot be too large, and the discharge amount is too large to mean that the backflow amount is too small, namely, the amount of the soybean milk which returns to the grinding body again for repeated grinding becomes small, which is not beneficial to full grinding, is not beneficial to the stability of fineness and is not beneficial to the stability of the concentration;
and S4, grinding to form soybean milk discharge, and keeping dynamic balance of the feeding amount and the discharging amount, wherein the grinding process is a dynamic balance process, and meanwhile, the stability of the feeding liquid level is also kept unchanged, so that the dynamic balance of the feeding amount and the discharging amount in the grinding process needs to be kept, and the continuous stable production is realized.
In conclusion, when the soybean grinding device and the soybean grinding method in the scheme are used for grinding soybeans, the traditional two grinding steps of coarse grinding and fine grinding are abandoned, so that the whole soybean grinding process can be completed only by one grinding, the probability of equipment failure is reduced by half, and the equipment maintenance is reduced. In addition, the device is not easy to block in use, so that the device does not need to be frequently disassembled and manually cleaned. Finally, the grinding equipment, namely the corresponding grinding method, is used for grinding the soybean milk, the backflow structure can greatly reduce the gas content in the soybean milk, and meanwhile, the feeding liquid level is kept to prevent a large amount of air from entering, so that the generation of bubbles is reduced. And the grinding fineness and the concentration of the soybean milk in the scheme are more stable, and the method is suitable for industrial continuous production.
