摘要
滚筒式清洗机是借圆形滚筒的转动,使原料在其中不断地翻转,同时用水管喷射高压水来冲洗翻动的原料,以达到清洗目的。污水和泥沙由滚筒的网孔经底部集水斗排出。该机适合清洗柑橘,橙,马铃薯等质地较硬的物料。本滚筒式清洗机,是一种比较实用的食品初加工机械,它是由机架、电机、皮带传动系统、减速器、联轴器、链轮传动系统、轴承、螺旋式滚筒、冲洗水管、挡料板、出料机构组成。电机、减速器固定在机架上,电机通过皮带传动系统与减速机相连,减速机通过联轴器与小链轮相连,大链轮带动滚筒上的摩擦轮而使得滚筒转动,滚筒内部有螺旋导板,在旋转的同时,带动食品排出,本新型滚筒式清洗机具有结构简单、能耗低、工作可靠、制造成本低和节约用水的优点。

Abstract
Drum type washing machine is a circular cylinder by rotation, in which the raw materials continue to flip, while high-pressure water spray with a hose to wash turning raw materials to achieve the cleaning purpose. Water and sediment from the bottom of the drum set by Pelton mesh discharged. Washing machine for citrus, orange, potatoes and other hard materials textur,The drum washing machine, is a relatively early use of food processing machinery, which is from the rack, motor, belt drive system, reducer, coupling, sprocket drive system, bearings, spiral rollers, wash water , block plate, the material agencies. Motor, gear rack fixed to the motor through the belt drive system is connected with the reducer, speed reducer is connected through the coupling and the small sprocket, large sprocket driving the friction wheel roller and makes rotating drum, drum inside have a spiral Guides, in the rotation ,at the same time, promote food discharge, this new type of drum type washing machine has benefits of simple structure, low energy consumption, reliable, low manufacturing cost and water conservation
