Our respect point during designing flash dryer is to disperse solid caky material as fine as possible, which increased surface area of raw material and speed up heat transfer process. Required air is filtrated by air filter, and send to air heater by blower to be heated.

 

    The hot air enters into the bottom of the drier in tangent direction. Under the driving of the stirrer, a powerful rotating wind field is formed. The paste state materials enter into the drier through the screw charger. Under the powerful function of the stirring vanes at high-speed rotation, the materials are distributed under the function of strike, friction and shearing force. The caky state materials will soon be smashed and contact the hot air fully and the materials are heated and dried. The dried materials after the de-watering will go up with the heat-air flow. The step rings will stop and keep the big particles. Small particles will be discharged out of the drier from the of the equipment by centrifugal force function and be smashed again after they fall down to the bottom.

 

 

    (1)  Raw material is processed by cutting, shearing, blowing, floating and rotating, then become granulated shape and separated greatly, the relative velocity between solid phase and gas phase is great, this strengthens the process of heating exchange. Therefore , this machine has strong drying capacity.

    (2) This machine combines the whirl technology with the fluidity .ejection and smashing step technologies , can be used for a wide range.

    (3) Drying hot air enters into the bottom of machine and formed strong rotating airflow, it can wash out material sticking on inside surface .

    (4) In high temperature area at bottom of equipment, heat sensitive raw material will not directly contact with heating surface. As a result, carbonization and color change problems can be solved.

    (5) A segmenting ring and a rotational flow piece are equipped in the upper drying room in order to control granulated size and finished products wet containing rate.

    (6) Spin flash dryer is running under tiny negative pressure, There is no need other smashing machine to crush raw material , circumstance pollution will not occur.

    (7) A segmenting ring and a rotational flow piece are equipped in the upper drying room in order to control granulated size and finished products moisture to satisfy required containing rate and granulation.

    (8) Design with compact construction and small occupation, the equipment is easy to control and maintain.

    (9) The main parts of the equipment is easy to replacing , the key controlling data is adjustable which will adjust material staying time and suitable for more variety of raw material .
