Changzhou dryer manufacturers supply: large slime dryer, the slime dedicated dryer, chicken manure dryer equipment. Overview: hollow shaft arranged in dense wedge-shaped hollow blades, heat medium hollow axial blades. The unit effective volume of a large heat transfer area, the heat medium temperature from -40 ° C to 320 ° C, can be water vapor, may also be a liquid type: such as hot water, thermal oil, etc.. Indirect conduction heating, there is no air to carry away the heat, the heat is used to heat the material. Only heat loss through the device body insulation layer heat to the environment. The wedge-shaped blade heat transfer surface has a self-cleaning function. Material particles and the relative motion of the wedge surface scrubber to wash off the wedge-shaped attachments to the surface of the material, the operation has maintained a clean heat transfer surface. The blades of the dryer housing for the W-type general arrangements for two to four root hollow stirring shaft within the housing. Housing sealing cover and the top cover to prevent dust leakage of materials and the collection of materials solvent vapors. At the outlet of a block pull to ensure that the height of the material level, the heat transfer surface covered by material and give full play to the role. The heat medium through the rotary joint flows through the housing jacket and hollow shaft, the heat medium based on the type of hollow stirring shaft and having a different internal structure, to ensure optimum heat transfer effect. Applications: paddle dryer has been successfully used in the food, chemical, petrochemical, dyes, industrial sludge, and other fields. The characteristics of the equipment heat transfer, cooling and stirred so the following unit operations: calcined (low temperature), cooled, dried (solvent recovery), heating (melting), the reaction and sterilization can be accomplished. While stirring blade is the heat transfer surface, so that the heat transfer area increases, the effective volume of the unit to shorten the processing time. The heat transfer surface of the wedge-shaped blade has a self-cleaning function. Compression - expansion agitation so that the material mixture evenly. "Piston flow" the material in the axial direction into movement in the axial interval, the material temperature, humidity, degree of mixing small gradient.
