DW single layer belt dryer

Product Introduction

This machine is a continuous flow drying equipment used for drying sheet, strip, and granular materials with good breathability. It is particularly suitable for materials with high moisture content, such as dehydrated vegetables and traditional Chinese medicine slices, but not allowed to have high temperatures; This series of dryers has the advantages of fast drying speed, high evaporation intensity, and good product quality. For dehydrated filter cake like paste materials, they can also be dried after granulation or rod-shaped production.

Performance characteristics

It can adjust the air volume, heating temperature, material residence time, and feeding speed to achieve better drying results.

The equipment configuration is flexible and can use mesh belt flushing system and material cooling system.

Most of the air is recycled and highly energy-efficient.

A unique air distribution device ensures more uniform distribution of hot air and consistency of product quality.

The heat source can be steam, heat transfer oil, electric or coal-fired (oil) hot air furnaces.

Operational principle

The material is evenly laid on the mesh belt by the feeder, and the mesh belt is generally made of 12-60 mesh stainless steel wire mesh, which is dragged by the transmission device and moved inside the dryer. The dryer is composed of several units, each with independent circulation of hot air. Part of the exhaust gas is discharged by a dedicated dehumidification fan, and the exhaust gas is controlled by a regulating valve. The hot air passes through the mesh belt covered with materials from bottom to top or from top to bottom to complete the process of heat and mass transfer, taking away the moisture of the materials. The mesh belt moves slowly, and the running speed can be freely adjusted according to the material temperature. The dried finished product continuously falls into the feeder. The upper and lower circulation units can be flexibly equipped according to user needs, and the number of units can also be selected according to needs.

Adapt to materials

Dehydrated vegetables, pellet feed, monosodium glutamate, coconut, organic pigments, synthetic rubber, polypropylene fiber, pharmaceuticals, medicinal herbs, small wood products, plastic products, electronic device free aging, solidification, etc.
