滚筒式分级机是食品工厂常用的原料预处理机械,通常用于果蔬类原料的大小分级,由于多为单机,大多数食品厂家均自行设计制造,但设计条件有限,设计不能达到较高水平。本文就此类机器的设计作一定程度的探讨。 Roller classifier is a commonly used raw material pretreatment machinery in food factories. It is usually used for the classification of fruit and vegetable raw materials. Since most of them are single machines, most food manufacturers design and manufacture their own products. However, the design conditions are limited and the design can not reach a higher level. This paper discusses the design of such machines to some extent.
