Features
Industrial Mesh Belt Dryer
It is a kind of batch, continuous production equipment.The main heating mode are electric heating and steam heating.Its
main working principle is to spread the material evenly on net belt combined with 12-60 wire-mesh belt . The dried
material is draged by the transmission device moving back and forth in the dryer machine. hot air passing through the
materia, then water vapor is eliminated from the wet hole, so as to achieve the purpose of drying.The cabinet is
combined by standard length section. In order to save space,The dryer can be made into multi-layer types,normally
there are two room with three layers , two rooms with five layers.Its length can be 6-40 m and width is 0.6-3.0 m.
1. mount 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 effect.
2. Equipments configuration is very flexible. It can use the netlike belt washing system and cooling raw material system
3. Hot air can be circular Unique air dividing device, it makes hot air distribute uniformly; this can guarantee products quality
4. Heating source can be selected from steam, conducting heat oil, electricity, coal furnace and oil burner
5. Hot air go through material layer from bottom to top and from top to bottom, it increases the contact area of material and hot air
and also the drying intensity.
6. We adopt unique internal air blowing device. It not only increases the relative speed of material and hot air and drying intensity
but also the uniform drying of materials.
7. It is fully enclosed structure. There is no outer air pipes except the dehumidifying air pipe, thus the materials won’t be polluted
and the heat efficiency and working condition are improved.
8. It is easy to contact with all parts inside the main machine, so it's easy for cleaning.
9. The belt speed can be controlled easily to guarantee the final moisture of products.
10. Easy to assemble, after assembling the conveyor elevator the machines can be working.

1, Food vacuum packaging machine working process is relatively
simple, Put the food into the packing bag in advance. food vacuum
packing machine exhausted the air in the packaging bag to reach a
predetermined vacuum degree. Then complete the sealing process.
2, The main role of food vacuum packaging machine is deoxidize to
prevent food spoilage.
3, The principle of food vacuum packaging machine also is simple,
because food spoilage caused by microbial activity, and most
microorganisms (such as mould and yeast) survival is need oxygen.
Vacuum packaging is use of this principle, the cell oxygen of the
packing bag and the food inside was removed, made the microbial lose
"the survival of the environment".
4, Food vacuum packaging machine, not only can inhibit microbial
growth and reproduction, but also can prevent food oxidation.
Widely used in food, medicine, chemical vegetables, seafood,
medicine, cosmetic, tea, chemical raw materials, all kinds of
electronic products, hardware components, rare earth metal
industries .
