Raw materials are uniformly fed on the mesh-belt / plate belt by distributor. The mesh-belt / plate belt is drawn and moved inside the dryer by a driving device. The dryer is consisted of several independent drying sections. Hot air circulated separately and independently in each section. Part of damp air will be exhausted by exhausting fan. Hot air penetrates the belt from top to bottom or from bottom to top, and this will complete the heat and mass transfer process. Moving speed of belt is adjustable. The top and bottom circulation units can be freely equipped according to customer's requirement.
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.
