fluidized bed dryer for vitamin capsules/hot air drying machine for cocoa powder/coffee

Product Description

Features of GFG -1non-standard fluidized bed dryer

◆ _The machine is disposed different air flow, air pressure and area temperature according to water evaporating characteristic of material and specific gravity after dehydrated in drying process.

◆ _It adopt stirrer device at feeding part, strength material’s fluidization effect in hot air, could avoid agglomeration of material because of high water content and material accumulation because of big feeding quantity.

◆ _It adopt cyclone separator behind drying room. Bag filter and washing tower as option by requirement.

◆ _It is especially suitable for the low temperature, heat-sensitivity material.

◆ _There are many kinds feeding equipment for choosing and feeding is continue and static.

◆ _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.

◆ _There are pressured seal and bearing cooling device, so can make the life of machine fluidized bed dryer for vitamin capsules/hot air drying machine for cocoa powder/coffee.

◆ _There is special equipment for sharing wind, and raising the amount of hot air.

◆ _There are rotational flow pieces inside the drying chamber. It is used to control the moisture and granule of raw material to needed level.

◆ _The machine could add specific gravity of materials compare with other drying method.

◆ _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. 8. It is possible for small equipment to carry out large-scale production.

Pricnciple of GFG-1non-standard fluidized bed dryer

◆ _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.
