Boiling drier, is a kind of drying equipment, also known as fluidized bed, generally by the heater, boiling bed main machine, cyclone separator, bag filter, a draught fan, operation table. According to the properties of different materials, can be optional or bag dust collector cyclone separator.
Boiling dryer is the use of air through the heat exchanger after heating, the formation of air into the host through the valve plate distribution, wet material from the feeder into the dryer, by the action of wind pressure, material to form a boiling state in the dryer, and extensive contact with hot air, thus completing the material drying in a short time.
Boiling dryer operation: the delivery of material to fluidized bed by car, the sealing ring and sealing by boiling bed in the cylinder lifting effect. Then, the air in the role of wind power, the purification filtering device, the radiator heating, the air distribution plate distribution in fluidized bed. The hopper material to form a boiling state in air and under stirring in the contact area, gas, solid, material internal moisture evaporation in a relatively short period of time and with the exhaust air away, the material is dry.
Because of the temperature distribution in the fluidized bed is uniform, can avoid any local overheating product, so especially suitable for some thermal drying; in the same equipment can be continuous operation, also can be intermittent operation; heat transfer effect is good, the temperature inside the bed is relatively uniform, thermal capacity coefficient is very high, large production capacity; the residence time of material in the dryer can be adjusted according to need, so the product moisture stability; independent electrical cabinet and PLC human-computer interaction control, integrated all drying parameters setting, safe and convenient operation; the drying device a few mechanical transmission components, low investment cost of equipment repair, less workload.
Through the powder granulation, improve liquidity, reduce dust emissions; improving the solubility through the powder granulation; mixing and granulating, drying completed in one step inside the machine granulation; antistatic fabric, safe operation of equipment, boiling dryer set pressure relief hole, when the explosion occurred, the operating personnel can not be damaged; no dead angle, material loading and unloading fast, clean, meet the GMP specification.
The discharged by turning over, to facilitate the prompt and thorough, be designed by automatic feeding system. Airtight negative pressure operation, airflow through the filter. Simple operation, convenient cleaning, is in line with the requirements of the ideal equipment for'GMP'.
