Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to screening equipment for food processing. Background Art

[0002] In the processing of many foods, it is necessary to screen the granular food raw materials in order to remove the raw materials whose particle size does not meet the requirements.

[0003] The rotary drum screen is one of the most commonly used screening equipment in the food processing industry. It is composed of a number of sieve holes on a rotatable inclined cylinder with openings at both ends. After the material is poured into one end of the sieve drum, the material will slide down along the inner wall of the sieve drum during the rotation of the sieve drum and be screened by the sieve holes. The overall structure is simple and the operation is stable.

[0004] However, most of the existing rotary drum screens have only one sieve hole, and therefore can only perform single screening. In addition, when the screen drum of the new shoe is rotating, it is difficult to control the speed at which the material slides down in the screen drum, which will cause some material to be discharged directly from the discharge end of the screen drum without being screened. This needs to be improved. Utility Model Content
