DW hot air circulation single-layer belt dryer
Product Introduction
DW single-layer belt dryer is a through-flow continuous drying equipment, which is used to dry sheets, strips, and granular materials with good air permeability. For dehydrated vegetables, Chinese Herbal Pieces, etc., the water content is high, and The temperature is not allowed to be particularly suitable for high materials; this series of drying machine has the advantages of fast drying speed, high evaporation strength and good product quality. It can also be applied to the dehydrated filter cake-like paste materials after being pelletized or made into rods
Performance Characteristics
◎ can adjust the air volume, heating temperature, material retention time and feeding speed to achieve the best drying effect.
◎The equipment configuration is flexible. It can use the mesh belt washing system and the material cooling system.
◎ Most of the air is recycled and highly energy-efficient.
◎ The unique air distribution device makes the distribution of hot air more uniform and ensures the consistency of product quality.
◎The heat source can be supplied with steam, heat transfer oil, electric or coal-fired (oil) hot air furnace.
Working Principle
Material is evenly laid on the mesh belt by a feeder. The mesh belt generally adopts a 12-60 mesh stainless steel mesh and is moved by a transmission device to move in the dryer. The dryer consists of several units. Each unit has its hot air circulates independently. Part of the exhaust air is discharged by a special dehumidifying fan. The exhaust gas is controlled by a regulating valve. The hot gas from the bottom up or from top to bottom passes through the mesh belts covered with materials to complete the heat and The process of mass transfer takes away material moisture. The mesh belt moves slowly, the operating speed can be adjusted freely according to the material temperature, and the dried product continuously falls into the receiver. The upper and lower circulation units can be flexibly equipped according to the needs of users, and the number of units can also be selected according to the needs.
Adapt
Adapt to the dehydrated vegetables, pellet feed, monosodium glutamate, coconut, organic pigments, synthetic rubber, acrylic fiber, medicines, herbs, small wood products, plastic products, electronic devices without aging, curing and so on.
