Description

The flash dryer is widely used for drying Soya bean mud ,rubber and plasticizer, agrochemical, pigment, dyestuff, chemical industry, animal feed, medicine and kinds of intermediates.

Principle 

Hot air enters into stirring and crushing and drying chamber from the bottom of dryer with suitable speed.It exerts strong shearing,blowing,floating and rotating effect to wet product. Therefore raw material is granulated through centrifugal force,shearing ,impacting and friction effect.It strengthens the process of heat exchange.At the bottom of dryer,the large and damp granule is crushed under the action of stirrer and the granule that is small in partical and contain less moisture will lift accompainied with revolving air stream.During the period of lift,it is dried further.Because gas and solid two phases flow in heat exchange,so the machine has strong drying capacity.

Features

◆ There are many kinds of feeding equipment for choosing,and feeding is continue and static.

◆ At the bottom of dryer, where is high temperature area, heat sensitivity raw material can not 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 cooling 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 granle of raw material.

◆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.
