1. General description of Belt dryer
Belt dryer is a continuous-working type drying equipment. It can be widely used in chemical, pharmaceutical, foodstuff, building materials, and electron industries. It is specially suitable for drying the flaking shape, strip shape, and granule materials with good ventilating. To filter cake and cream materials, they can be shaped by granulator or extruder, and then be dried by belt dryer.
Materials that to be dried are distributed on the conveyer belt by feeding device. Conveyer belt will go through the channel that consists of one or several heating units. Each heating unit is equipped with air heating system and circulation system. And Each channel has one or several dehumidifying system. When the conveyer belt goes through it, hot air will pass though the material that on the belt from up to down or from down to up so that the material can be dried uniformly. Heating source can be steam, heat transfer oil, flue-gas or electricity. Fan is used for heat convection and transferring heat to material, and fresh air is supplied and damp air is exhausted. In the drying time cabinet, proper relative temperature and humidity can be kept.
2. Application of Belt dryer
Foodstuff industry:Coconut chip, Desiccated coconut, seaweeds, sliced fruit, vegetables, mushroom essence, chicken essence, gourmet powder, plant, flowers and so on.
Pharmaceutical industry: Chinese herbal medicine, pills, medicine granules so on.
Chemical industry:Iron oxide (shaped to flaking shape), fiber, soap base, titanium oxide, sludge and so on.
