Description
技术领域technical field
本发明涉及一种筛选装置，尤其是涉及一种无级自动物料筛选装置，属于食品设备加工技术领域。The invention relates to a screening device, in particular to a stepless automatic material screening device, which belongs to the technical field of food equipment processing.
背景技术Background technique
筛选机，也被称为振动筛，是一种非常常见的用于颗粒物料进行筛分的机械。筛选机的工作过程基本就是通过物料在筛面进行震动或者滑动，从而使得比筛网孔径小的物料透过筛面被筛选出来，而体积较大的物料则被留在筛面上。例如筛选花生、豆类、米类等等，通过筛选把粒径不同的异物或半粒豆、碎豆筛除。A screening machine, also known as a vibrating screen, is a very common type of machinery used to screen granular materials. The working process of the screening machine is basically to vibrate or slide the materials on the screen surface, so that the materials smaller than the aperture of the screen are screened out through the screen surface, while the larger materials are left on the screen surface. For example, screening peanuts, beans, rice, etc., through screening to remove foreign objects with different particle sizes or half-grain beans and broken beans.
现有的筛选机多为单一物料的筛选，即一种物料筛选机只能筛选一种物料，利用率低，当然如果工厂只生产一样加工食品，的确可以选择一个固定的机型。若需要筛选多个不同品种的物料，则需要更换不同规格的筛选机。例如筛选花生壳、花生、大米及豆类等等，现有的筛选装置很难完成。而且现有筛选机比较笨重，箱体和基座一般是固定在一起，难于移动及运输。Most of the existing screening machines are single-material screening, that is, one material screening machine can only screen one material, and the utilization rate is low. Of course, if the factory only produces one processed food, it is indeed possible to choose a fixed model. If you need to screen many different kinds of materials, you need to replace the screening machine with different specifications. For example, screening peanut shells, peanuts, rice and beans, etc., is difficult to complete with existing screening devices. And the existing screening machine is relatively heavy, and the box body and the base are generally fixed together, which is difficult to move and transport.
