      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.

    Machine structures
    1. Inlet air system
    The inlet air system consists of Primary filter, middle efficiency filter, high efficiency filter (Optional) and heater with accurate temperature control. The inlet air flow, speed and pressure is variable and controllable. For the heater , it can be steam radiator ,electrical heater , gas furnace and so on .
    2. Main Machine Structure
    mesh-belt generally adopts 12-60 mesh stainless steel mesh and it is drawn by a transmission device The main body structure consists of mesh-belt, belt transmission device , heater, exhaust fan.
    3. Exhaust sir system
    The exhaust dust collection filter is optionally designed for protect environment.

     1. Air quantity, heating temperature, materials staying time and feeding speed can be adjusted in order     to improve drying quality.

     2. The equipment configuration is flexible. The mesh belt washing system and materials cooling system are available to use.

     3. Most of the hot air is reused to realize energy saving.

     4. The machine is equipped with unique air distributor; it distributes the hot air to the dryer and

     ensured the quality of products is constant.

     5. The heat source can use steam, thermal oil, electricity, coal (oil), or hot air furnace.

     6.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.

     7.The equipment has no dead corner so it is easy to clean fully and there is no cross pollution;

     8. Machine materials : AISISUS304 , AISISUS316L, and other material .

     9. For the electrical component  , we mainly use international brand such as ABB ,Siemens or Schneider.

     10. Control system has more choices, such as push button , HMI+PLC and so on.                                      

     11. Fan speed is controlled by VFD (Optional), and it can adjust the air volume .

     12. Belt speed is controlled by VFD (Optional), and it can adjust the drying time base different moisture of materials.




      The 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 making or bar making, can be dried also.

    Optional Choices
    For the main electrical components , Hywell have international brand choices such as ABB , Siemens or Schneider or others.
    For the material for the machine , Hywell have choices on AISISUS304 , AISISUS316, ,carbon steel and so on .
    For the control system , Hywell have choices on push button, PLC+HMI and so on .
    Hywell can design the explosion-proof system for our dryer based on the customer request.
    For the heating system for the machine , it is very flexible. Hywell can configure it based on the customer site conditions ,such as steam ,electricity , and so on , all of them Hywell can design it to match our dryer.
