principle of work:Hot air enters into stirring and crushing and drying chamber from inlet at the bottom of drier with suitable spraying speed and exerts strong shearing,blowing ,floating and rotating effect to raw material.therefore taw material is guanulated through centrifuge,shearing ,impacting and rubbing effect.it strengthens the process of heat exchange and mass transmission.at the bottom of drier,the lage and damp ball is crushed under the action of stirrer and the granule that is small in particle and contains less moisture will lift accompanied with revolving air stream.during the period of lift,it is dried further.because gas and solid two phases flow in rotating and the inertia of solid phase is more than that of gas and the relative velocity between solid and gas phases is large ,so it strengthens the process of heat exchange.therefore the machine has strong drying capacity.
characteristic
Rraw material becomes particulate that exists in high dispersing state caused by centrifuge,shearing,impacting and rubbing effect.moreover the relative velocity between solid and gas phases is large,so it strengthens the process of heat exchange and mas transmission.therefore the machine has strong drying capacity.
Dry gas enters into the bottom of drier and produces strong rotating air stream that exerts strong rushing effect to raw material on the wall,therefore the phenomenon of adhesive wall is removed.
At the botton of drier,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 thermas sensiticity 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 .it is possible for small equipment to carry out large-scale production.
There ate rotational flow pieces inside the drying chamber.it is used to control the moisture of raw material to the needed low level.
The diatributor at the top of drying chamber can control the size and moisture of fuanule to be discharged.
