flash dryer

Specifications

It is used for stirring and crushing, at a proper speed. It causes the materials to float and rotate at a high speed.

1,Principles    

Hot air is sprayed from the bottom of the dryer into a drying chamber, which is used for stirring and crushing, at a proper speed. It causes the materials to float and rotate at a high speed. Thus, the materials are granulated through centrifuging, shearing, impacting and rubbing. And the process of heat transmitting is also strengthened. At the bottom of the dryer, large and damp, lump granules are crushed under the action of the stirrer. While small granules contain less moisture will be brought up by the rotating air flow. During this period. They are dried further. As the inertia of the solid is larger than that of gas, the solid and gas will flow rotairly at a high relative speed. So the process of heat transmitting will be strengthened again. Therefore the machine has a high drying capacity.

2,Featurs

As the materials are granuled through centrifuging, shearing, impacting and rubbing. Moreover the relation velocity between solid and gas phases is high, so it strengthens the process of heat transmitting. Therefore the machine has a high drying capacity.

Dry gas enters the dryer the from bottom which produces strong rotating air flow and also carries out an action of strong rushing onto the raw materials on the inner wall of the dryer. So there is no phenomenon of materials sticking on the inner wall.

At the bottom of the dryer, where the temperature is very high, a special device is equipped to prevent heat sensitive materials from contacting with the heat surface directly. Therefore, it solves the problem of heat sensitive materials carbonization and color changing.

As the rotating speed of the gas inside the drying chamber is very high and the staying time of the materials is very short, high efficiency, high drying speed, small equipment, large out put can be achieved.

There are elutrating rings and rotating flow separators equipped in the upper part of the drying chamber in order to control the size and humidity of the granules so as to meet different requirements.
