This elevator machine is mainly made of stainless steel and food grade plastic polyethylene (PE), which is safe and hygienic. The control circuit and material level control realize the automatic feeding and stopping functions. It is suitable for the vertical lifting of granular materials in grain, food, feed and chemical industries. The elevator drives the hopper to lift through the transmission of the chain, and is used to vertically transport granular and small block materials. It has the advantages of large lifting capacity and high lifting degree. It can be combined with a computer scale and packaging machine to form a quantitative automatic packaging system, which is widely used in the food packaging industry.
