Paddle dryer have blade inside the device, the wet material is stirring with the paddle, full contact with the hot surface and the heat carrier, so as to achieve the purpose of drying. It’s a low-speed stirring dryer. The structure is generally horizontal, double-axis or four-axis.
Paddle dryer type is hot air type and conduction type, hot air type means the material is in contact with each other by a heat carrier (eg hot air) and dried with, the heat conduction type means in contact with each other not the carrier material but with the hot surface of the material. Conduction type advantage is that the material cannot easily be contaminated, less exhaust, high heat efficiency, the volume is relatively small, is conducive to energy conservation and the prevention of air pollution.
Plastic, resin products, inorganic chemicals, fertilizers, feed, food, chemical fiber, dyes, starch, drain sludge and other products drying. Such as: vinyl chloride, resin, nylon, polyethylene, polypropylene, starch, sodium chloride, sugar, iron chloride, feldspar, caustic powder, sodium carbonate and other powder and paste material.
1. The device is compact, takes small place, high heat conductivity, excellent heat efficiency, generally up to 80% -90%, it is energy efficiency equipment.
2. The low rotation speed keep granular and sheet material completely.
3. Wild material adaptability, operating flexibility, residence time from minutes to hours, can be adjustable.
4. The attachment is simple, low investment and low operating costs.
5. The usage of this machine can be used for drying, cooling, gas recovery, the reaction and heating (pre-sterilization) and other technology operations.
