This equipment is a continuous through-flow drying system designed for drying strip, piece, and granular materials with excellent air permeability. The machine is ideal for materials such as dehydrated vegetables, traditional Chinese medicinal herbs, and similar products that have high moisture content but cannot withstand elevated drying temperatures. The machine offers the advantages of rapid drying speed, high evaporation efficiency, and superior product quality. Dewatered filter cake or paste-like materials must be formed into granules or strips prior to the drying operation.

Features of Multilayer Belt Dryer

1. The heated air stream flows upward through the mesh belt and material layer from the bottom, thereby guaranteeing consistent heat distribution. This drying system delivers high production efficiency and excellent quality.
2.  This multi-tier conveyor dryer utilizes lifting mechanisms with a uniform feeding device, and the material layer thickness can be continuously adjusted through variable control.

Working Principle: The materials are evenly spread onto the mesh-belt through the material feeder. The mesh-belt typically uses 12-60 mesh stainless steel screening and is driven by a transmission mechanism, moving throughout the dryer. The dryer consists of multiple sections, with each section maintaining independent hot air circulation. A portion of the exhaust gas is discharged via a dedicated moisture removal blower. The exhaust gas flow is regulated by an adjustment valve. The hot air penetrates through the material-laden mesh-belt either from top to bottom or from bottom to top, thereby accomplishing the heat and mass exchange process. This process removes moisture content. The mesh-belt advances gradually, with running speed freely adjustable based on material characteristics. The finished products following the drying process drop into the material collection unit continuously.
