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.
a. Most hot air iscirculated in the cabinet, heat efficiency is high and save energy.
b. Use forced ventilationand cross flow type drying principle, there are air distribution plates in thecabinet and material is dried uniformly.
c. Low noise, stableoperating, self-control temperature and convenience to install and maintain.
d. Wide scope ofapplication, it is suitable for all kinds material, and is the general typedrying equipment
