Working principle: Wet material delivered into bed face with open slot from the inlet is in a condition of throw or half-throw under the effect of exciting force, and flows to the outlet at a uniform speed. Hot air blasted out though open-slot at the bed face sufficiently contacts and exchanges with flowing layer of material. At the same time afterheat air and evaporating moisture are released from exhaust hole at the upper shell. The end product after drying is continuously taken out from outlet. The tail gas is exhausted to the dust collector from top outlet.

Applied scope: This machine is applied to loose powder material with low wetness, wide range of particle size and particle material for granulation.

Main merits:
As the material being dried can be fluidized very well due to concerted action of chemical vibration and hot air, it is especially applied to the material with critical fluidized-speed, wide range of particle size and the material which  taken-out speed is difficult to define. with low wetness, and can save energy 10% to 30% contrasted with drying equipment with single layer.
Residence time of the material in the bed surface can be stpelessly changed by means of adjusting the direction and amount of the exciting force.  The operation is easy to hold, and  the process is stable.
The operation for drying, cooling and humidification can be carried out according to the requirements of process. At the same time the combination operating both for drying and cooling can be carried out as well.
Especially applied to the drying occasion that the particle shape after being dried and the particle crystal need to be protected.
