[0002] Food processing refers to the grain grinding, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as processing activities of vegetables, fruits, nuts and other foods that directly use agricultural, forestry, animal husbandry and fishery products as raw materials. With the development of modern industry, the requirements for food processing equipment are constantly increasing.

[0003] When food is processed, it is necessary to crush the larger raw materials, and then screen and mix the crushed raw materials. The existing traditional crushing device has a relatively simple structure, mainly including a crushing box with a feed port at the upper end and a discharge port at the lower end. Pairs of crushing rollers are installed in the crushing box, and a driving assembly for driving the crushing rollers to rotate is also included. In the actual working process, the materials put into the crushing box are crushed by two sets of crushing rollers rotating in opposite directions.

[0004] In the actual working process, it is found that when the existing grinder grinds raw materials of different particle sizes, due to the different particle sizes of the raw materials, directly placing them on the same level for grinding will make the degree of grinding of materials of different particle sizes different. After the same time of grinding, some large particles of raw materials have not been crushed more thoroughly, while some small particles of raw materials have been crushed to the degree of fine dust, so that the final crushed particle sizes are different, the degree of grinding is difficult to be the same, and the specifications of the product are difficult to guarantee, which affects the subsequent use; in addition, the above-mentioned existing grinder does not have a screening function, and cannot perform screening operations on the crushed materials. The crushed materials need to be collected and transferred to the screening device for screening operations. The operation process is cumbersome. Therefore, it is urgent to design a homogenizing grinder to solve the above problems. Utility Model Content

[0031] Working process:

[0032] First, the rotating shaft wrench 17-2 in the flip driving structure 17 is turned to rotate the flip shaft 17-1, so that the flip valve plate 18 installed on the flip shaft 17-1 is flipped and the upper end of the flip valve plate 18 is placed on the first bridge plate 19, thereby ensuring that the materials put into the crushing box 13 can smoothly fall between the two groups of small crushing rollers 11 and cannot fall between the two groups of large crushing rollers 12;

[0033] Then, materials are put into the feed hopper 21. Under the filtering and screening action of the filter valve device 22, small-sized materials fall into the crushing box 13, and under the guidance of the flip valve plate 18, the first strap 19 and the second strap 20, they fall between the two groups of small crushing rollers 11. The two groups of small crushing rollers 11 rotating in opposite directions can crush the small-sized materials. After working for a period of time and completing the crushing operation of the small-sized materials, the shaft wrench 17-2 in the flip driving structure 17 is reversed, and then the flip shaft 17-1 is reversely rotated, so that the flip valve plate 18 installed on the flip shaft 17-1 is reversed and the upper end of the flip valve plate 18 is ensured to be placed on the second strap 20, thereby ensuring that the feed hopper 21 is fed with materials. The material entering the crushing box 13 can smoothly fall between the two groups of large crushing rollers 12, and cannot fall between the two groups of small crushing rollers 11, and then the linear drive member 22-5 in the filter valve device 22 is started, so that the extended end of the linear drive member 22-5 is retracted, thereby driving the filter plate 22-2 to move to open the discharge port of the feed hopper 21. During the movement of the filter plate 22-2, the large-particle-sized material trapped on it falls downward through the opened discharge port of the feed hopper 21, and falls between the two groups of large crushing rollers 12 under the guidance of the flip valve plate 18, the first strap 19 and the second strap 20. The two groups of large crushing rollers 12 rotating in opposite directions can crush the large-particle-sized material;

[0034] The crushed material falls onto the primary screening plate 9 for primary screening operation. The material that meets the particle size requirements after crushing falls into the primary screening hopper 8, and the material that does not meet the requirements is retained on the primary screening plate 9; the transmission auger 4 rotating in the transmission cylinder shell 3 drives the material in the primary screening hopper 8 to be transmitted forward. During the transmission process, part of the material falls from several screening holes 6 opened at the bottom of the transmission cylinder shell 3 into a collecting chamber in the collecting box 2, and the remaining large-size material continues to be transmitted forward, and then falls into another collecting chamber in the collecting box 2 through the discharge port 5.
