Pharmaceutical 1600kg/h Evaporation SS304 Spin Flash Dryer

SFD Flash Spin Dryer Working Principle

SFD series spin flash dryer is a continuous flash drying processor with crushing device, it has been extensively used for drying damp and sticky filter cake and paste materials in chemical and food industry.

Wet material is fed into the drying chamber via screw feeder and drop onto a high speed rotating crushing device which will completely crush and disperse the wet bumps into fine particles. Meanwhile, heated and filtered hot air is blown swirly into the drying chamber from the bottom to form a strong swirl air flow. This strong air flow transports the fine particles through the cylindrical drying chamber, during which heat transfer happens and moisture evaporates. Dried product is separated and collected by cyclone and/or bag filters. Damp air is exhausted by the fan.

SFD Flash Spin Dryer Features

♦ There are many kinds feeding equipment for choosing, and feeding is continue and static.
♦ At the bottom of drier, where is high temperature area, heat sensitivity raw material cannot contact with heat surface directly, therefore it solves the carbonized and changed color problems of heat sensitivity raw material.
♦ There are air pressure equipment and shaft equipment, so can longer life of machine.
♦ There is special equipment for sharing wind, and raising the amount of hot air.
♦ There are rotational flow pieces inside the drying chamber. It is used to control the moisture and granule of raw material to needed level.
♦ The density will be added in the machine.
♦ Because gas speed at circle inside the drying chamber is high and the staying time of raw material is short, high efficiency and quick speed can be realized. It is possible for small equipment to carry out large-scale production.
