Battery materials battery materials double cone rotary vacuum dryer szg3500 double cone rotary vacuum drying equipment for the double cone rotating tank, the intermediate device is cylindrical, conical ends, one end is designed to open the top of the cone formula feeding (doubles manhole) the other end of the discharge valve. Cans vivo divided into three intermediate jacket heating medium can be steam, hot water or thermal oil circulation, insulating layer of the base fine glass wool, minimal power consumption; inner running material. Work tank in a vacuum state, to the jacket into a thermal oil, hot water or steam for heating heat medium, heat transfer to the wet material through the tank wall. Since the tank body in a vacuum, a variety of materials in the vehicle (including water) can rapidly vaporized under vacuum conditions at a lower temperature, and the rotating of tank so that the material constantly up and down, inside and outside turning, constantly updated material surface in contact with the wall, to make full use of the heat conducted by the walls, to speed up the drying rate of materials, increase drying efficiency, and to achieve uniform drying purposes. Evaporation of the solvent (water vapor) after the wet material absorbs heat out through vacuum exhaust pipe is withdrawn. Cryo midway through the system (using water or frozen brine) cooling, in order to achieve the purpose of recycling, saving production costs and improve the working conditions of the manganese oxide vacuum dryer double cone vacuum dryer, but also reduce environmental pollution . Double cone drier has double cone rotating tank, the tank in a vacuum state, to the jacket into the steam or hot water heating potassium sorbate special double cone vacuum dryer, heat through the tank wall and the wet material . After evaporation of water vapor wet material absorbs heat pump is pumped through the exhaust pipe vacuum drying process temperature drops relatively low, especially suitable for drying heat-sensitive materials, to keep the material color, smell and taste. To prevent drying tower have a sticky wall phenomenon, this device is provided with a special structure, effectively put an end to the phenomenon of sticking to the wall of the product. Unique wind supply system finished with the hot dry wet air in the system time to avoid the possibility of drying or agglomeration of the finished absorbent boiling point of the material the solution is reduced under vacuum, the evaporator heat transfer driving force increases for a certain amount of heat transfer amount can be saved evaporator heat transfer area; the heat source for operation of evaporation may be low pressure steam or boiling hot steam; less heat loss in the evaporator can be disinfected before drying Pharmaceutical special double cone dryer Rotary dry, dry process without any impurities mixed in, in line with 高标准 requirements; the use of a condenser, which can effectively recovered material in a solvent. Double cone rotary vacuum dryer double cone rotating tank, the tank in a vacuum state, to the jacket into the steam or hot water heating, heat through the tank wall in contact with the wet material, wet material after evaporation heat water vapor, out through vacuum exhaust pipe is pumped. Since the tank body in a vacuum, and the rotation of the tank so that the material inside and outside continue to flip up and down the double cone vacuum dryer, and therefore speed up the drying rate of materials, increase drying efficiency, to achieve uniform drying purposes. Double cone rotary vacuum dryer system consists of double cone rotary vacuum dryer, a condenser, dust, vacuum pumping systems, heating systems, cooling systems, electrical control system components.
