Description

Technical Field

[0001] The utility model relates to the technical field of raw material screening, in particular to a screening device for food processing raw materials. Background Technique

[0002] Food processing refers to the processing activities of directly using agricultural, forestry, animal husbandry, and fishery products as raw materials, including cereal grinding, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, and the processing of foods such as vegetables, fruits, and nuts. It is a type of broad - sense agricultural product processing industry.

[0003] In the prior art, food raw materials for food processing need to be screened before further processing. To ensure product quality, smaller food raw materials need to be screened and separated from larger ones. Usually, a vibrating screen is used, and an excitation force is generated by a vibrating motor to make the screen surface vibrate. The raw materials are affected by vibration and gravity on the screen surface, and particles of different sizes have different movement trajectories on the screen surface, thus achieving separation.

[0004] However, when food raw materials are screened by a vibrating screen, food residues appear on the screen of the vibrating screen. And some food raw materials have more moisture. When there is sufficient moisture, a large number of bacteria are generated on the screening net, and then when screening food again, it will cause food contamination. It is necessary to disassemble the screen for cleaning, which affects work efficiency. Moreover, the food remaining on the screen may absorb moisture in the air and become damp or dry and hard, resulting in the pores of the screen becoming smaller or blocked, affecting the efficiency and effect of subsequent screening, and reducing the screening accuracy. The food attached to the screen may change the actual aperture and shape of the screen, resulting in a change in screening accuracy.

[0005] Furthermore, when directly using a high - pressure water gun to clean the device, a large amount of water remains on the vibrating screen. If the water is not dried and the device works directly, it makes food more likely to produce bacteria. If you want to dry the vibrating screen, you still need to stop the machine, disassemble the screen and then dry it, with low work efficiency.

[0061] By rotating the threaded rod 8933, since spiral lines in different directions are provided at both ends of the threaded rod 8933, manually rotating the threaded rod 8933 makes the first moving block 8934 and the second moving block 8938 move towards both ends of the threaded rod 8933. By using the first moving block 8934 and the second moving block 8938 in contact with the rotating rod 8936, through movement extrusion, the clamping block 8935 rotates through the rotating rod 8936, so that the end of the clamping block 8935 away from the connecting block 8931 moves closer to the middle, clamping the air guide bag 83 and the storage bag 84.
