The materials are uniformly put on the mesh-belt by the material charger. The mesh-belt takes 12-60 mesh stainless steel wire net and it is drawn and moved inside the dryer by a transmission device. The dryer 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 adjusted valve. The hot air passes through the mesh-belt covered with the material from the top to the bottom or from bottom to the top and this will complete the heat and mass transfer process. This process will bring the material water away. The mesh-belt moves slowly, running speed can be freely adjusted according to the material temperature. The final products after the drying will fall into the material collector continuously. The top and low circulation units can be freely equipped according to the users' demand. The unit number can be selected according to the demand.
1.Dryer structure: five layer, five unit, the width of mesh belt is 2 meters, and the length of mesh belt is 9 meters(the effective drying area is 85m2).
2.The speed of mesh belt is frequency adjustable, it can ensure the residence time of materials and the quality of materials discharging.
3.Equipment consists of five controllable circulation units, each unit is equipped with fresh air supply filter (in order to guarantee the supplement of fresh air smoothly, internal air duct of drying oven has fresh air supply diversion bending pipe),heater, circulating fan, bypass duct filter, humidity-discharging outlet,etc.
4.The heater and circulating fan are installed at the bottom of mesh belt dryer, proposed bypass duct filter to avoid pollution, and the upper and the lower of each unit on both sides of dryer are equipped with quick-opening door which is convenient for cleaning and maintenance.
5.Five circulation units adopt hot air recycling, it can make the equipment energy consumption is lower and more reasonable.
6.The use of reasonable inclined guide wind device and material tray, can make air distribution uniformly in the mesh belt width direction , small temperature difference, clear material easily.
7.Material trays without holes are placed at the bottom of return net belt, for the purpose of material collecting and cleaning.
8.The equipment uses 80 mm thick rock wool insulation, good sealing, small heat loss, and the environment is clean.
9.Sealing gaskets are all white silicone rubber pad.
10.Equipment inside stainless steel 304 seal plate thicknessδ1.5, the inner wall is full welding, equipment outside stainless steel 304 seal plate thicknessδ1.0.
11.Exposed transmission chain and non-standard circulating wind shall equip with stainless steel hood (fan cover end with ventilation holes).
12.The surface of stainless steel with semi gloss treatment, the surface of carbon steel are coated with red lead anti-rust paint two degrees, aluminium paint one degree.
13.After the production of equipment is finished, transmission convey system shall test run, there should be no abnormal noise and jamming.
14.Equipment outside surface adopt Q235, for anti-corrosion paint processing.
15.In order to prevent dust pollution which is formed by the flying powder be detained in the drive chain, the stainless steel sheet is additionally added above the chain and mesh belt baffle plate as a shield, to prevent dust into the chain.
16.Total installed power: ~25.5KW
17.Steam consumption: 700kg/h~1000kg/h
18.Equipment weight:15600 kg
