Description:
materials are uniformly put on the mesh-belt by the feeder. The mesh-belt uses generally 12-60 mesh stainless steel wire net and it is drawn and moved inside the drier by a transmission device. The drier is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged with a special moisture elimination blower. The waste gas is controlled through an adjustment valve. The hot air passes through the mesh-belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the heat and mass transfer process.
Features
Different heating and circulation method is available for choice.
Length , width and layer quantity of belt is designed based on production requirement.
The machine pre-dehydration process could remove massive moisture on leaf surface, thus reduced the drying strength, and reduced the energy consumption.
Special hot air drying system, increase material penetrability and drying rate.
The adjustment of belt speed and the different section temperature control, it guaranteed the drying time and material quality and color.
Strong magnetism iron removal device is available for choice, it could remove metal impurities effectively.
