DW Series Mesh belt Drying Oven(Dryer Oven Machine)for food stuff , pharmaceutical
The mesh belt dryer is a drying device that uses a steel mesh as a conveyor belt to carry out continuous drying. Since the conveyor belt is in the form of a mesh, it is suitable for drying rules or irregularities of various masses (for example, coal mass, various mineral powder molding, food, vegetables, etc.). This unit can be used with other equipment. It can also be used alone. The equipment can be widely used in metallurgy, building materials, ceramics, fertilizer, chemical and other industries, and the mesh belt dryer is also an ideal equipment for drying food and vegetables.

Preface
This machine is a continuous penetrating flow drying equipment applied for drying material in strip ,particle or slice state and with good ventilation.The machine is suitable for the materials such as DE-watering vegetable, herbal medicine of traditional Chinese medicine and others, for which the water contents are high and high drying temperature is not allowed. For our DW series mesh belt dryer , it is one of our main equipments and very hot machine in our company.there are two types of mesh belt dryer , one is for drying the material, and the other is for cooling the material . The biggest difference between two machines is the mesh .

Principle
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 exhaust 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 property. The final products after the drying process will fall into the material collector continuously. The top and low circulation units can be freely equipped according to client requirements.
Advantage
1. High efficiency,low consumption and easy operation
2. No pollution,have heat insulating layer;fast heating,convenient to start and stop
3. The speed of mesh belt dryer could be controlled
4. The temperature of the mesh belt dryer could be adjustable according to the buyer demands.
Features
① Most hot air is circulated in the cabinet, heat efficiency is high and save energy.
② Use forced ventilation and cross flow type drying principle, there are air distribution plates in the cabinet and material is dried uniformly.
③ Low noise, stable operating, self-control temperature and convenience to install and maintain.
④ Wide scope of application, it is suitable for all kinds material, and is the general type drying equipment
⑤ Common control(Button control)or PLC and touch screen control are on request
⑥ Temperature controllable ;
⑦ Store memory of work-program mode and technological parameter and printing function (According to client’s requirements)
