DW Single-belt Dryer

Product introduction

This machine is a continuous penetrating flow dryingequipment applied for drying pieces strip and particles state materials with good ventilation. The machine is suitable for the materials such as dewatering vegetable, herbal medicine of traditional C hinese medicine and others, for which the water contents are high and high drying temperature is not a llowed.The machine owns the advantages, of fast drying speed, high evaporation capacity and good product quality . The de-watered & ltered cake state paste material should be made into particles or strips before drying process.

Characteristics

◎Amount of air , heating temperature, time of material sticking on the belt and velocity of feeding material can be adjusted in order to obtain the best drying ef fect.

◎Equipment’s conguration is very exible. It can use the netlike belt washing system and cooling raw material system.

◎Hot air can be circularly applied, the energy is greatly saved.

◎Unique air dividing device, it makes hot air distribute uniformly; this can guarantee products’ quality .

◎Heating source can be selected from steam, conducting heat oil, electricity , coal furnace and oil burner.

Working Principle

The materials a re uniformly distributed on the mesh-belt by the material feeder. The mesh-belt generally adopts 12-60 mesh stainless steel mesh and it is drawn by a transmission device and move inside the dryer . The dryer is composed of several sections. For each section, the hot air is circulated separatel y. Part of exhausted gas is exhausted by a special moisture exhaust blower. The waste gas is controlled by an adjustment valve. The hot a ir passes through the mesh-belt covered with bring water material away. The mesh-belt moves slowly, running speed can be freely adjusted according to the material property. The final products after the drying process will fall into the material collector continuously. The top a nd low circulation units can be freely equipped according to the user’s requirements. The number of section might be selected according to the production demands.

Material to be dried

De-watering vegetable, particle feed, gourmet powder, shredded coconut stuffng, organic color, compound rubber, acral fibre, medicine product,medicine material, small wooden product, plastic product, aging and solidification for the electronic component and device .
