First. Feature of Jingling Industrial hot air spin flash dryer/drying equipment /dryer machine  for milk powder

(1) There are many kinds feeding equipment for choosing and feeding is continue and static.

(2) There is a cooling device 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 metamorphose problem of heat sensitivity raw material.

(3) There are pressured seal and bearing cooling device, so can make the life of machine longer.

(4) There is special equipment for sharing wind, and raising the amount of hot air.

(5) There are rotational flow pieces inside the drying chamber. It is used to control the moisture and granule of raw material to needed level.

(6) The machine could add specific gravity of materials compare with other drying method.

(7) Because gas speed at circle inside the drying chamber is high and the staying time of raw material is short, so it could prevent material stick to me wall and metamorphose problem, high efficiency and quick speed can be realized. It is possible for small equipment to carry out large-scale production.

Second. Principle of Jingling Industrial hot air spin flash dryer/drying equipment /dryer machine for milk powder

Hot air enters into stirring and crushing and drying chamber from the bottom of dryer with suitable spouting speed. It exerts strong shearing, blowing, floating and rotating effect. It strengthens the process of heat and mass transfer. At the bottom of dryer, the large and damp granule is crushed under the action of stirrer and the granule that is small in particle and contain less moisture will lift accompanied with revolving air steam. During the period of lift, it is dried further. Because gas and solid two phase flow in rotating and the inertia of solid phase is more than that of gas and the relative velocity between solid and gas phase is large, so it strengthens the process of heat and mass transfer. Therefore the machine has large drying capacity.
