1. Descriptions
DW Belt Drying Machine is a continuous penetrating flow drying equipment applied for drying pieces strip and particles state materials with good ventilation. The machine owns the advantages, of fast drying speed, high evaporation capacity and good product quality.
2. Fruit Drying Device Principles
The materials are 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 separately. Part of exhausted gas is exhausted by a special moisture elimination blower. The waste gas is controlled by an adjustment valve. The hot air 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 collector continuously.
The top and low circulation units can be freely equipped according to the users requirements. The number of section might be selected according to the production demands.
3. Applications
Fruit Belt Dryer - DW Belt Drying Machine is suitable for the materials, such as de-watering de-watering vegetable, herbal medicine of traditional Chinese medicine and others, for which the water content rate is high and the high temperature is not allowed. The machine owns the advantages, that its drying speed is fast, the evaporation strength is high and the product quality is good. The de-watering filtering cake state paste material, after the particle makeing or bar making, can be dried also.
4. Attentions to Order
(1). Name of liquid materials, nature, solid content (or moisture content), viscosity, surface tension, PH value.
(2). Volumetric weight after drying, allowable residue moisture, granularity, allowed high temperature.
(3). Production, total shift hours per day.
(4). Available energy resource and volume of steam, power supply capacity, available volume of coal, oil and steam.
(5). Control requirement: If inlet and outlet temperature are needed automatic controlled.
(6). Requirement of powder collection: If bag collector is needed to install, environmental requirement of tail gasherbal The dewater
Features
1.the materials will put on the belt and materials do not moved on the belt ,so It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.
2.The equipment has no dead corner so it is easy to clean fully and there is no cross pollution;
3. Machine materials : AISISUS304 , AISISUS316L, and other material .
4. For the electrical component , we mainly use international brand such as ABB ,Siemens or Schneider.
5. Control system has more choices, such as push button , HMI+PLC and so on.
6. Fan speed is controlled by VFD (Optional), and it can adjust the air volume .
7. Belt speed is controlled by VFD (Optional), and it can adjust the drying time base different moisture of materials.
