Flash Evaporation DryingMachine

The flash evaporationdrying machine is new and highly efficient fluid drying equipment which isresearched and developed for the purpose of replacing the low-efficiency andhigh-consumption static drying previously used. We have used the features ofordinary fluid drying such as air stream drying, in the designing process, andhave created a flash evaporation drying machine which is much more advanced.

Operating Principle of the Flash Evaporation Drying Machine
Hot air enters into the stirring, crushing, and drying chamber from the bottomof the flash evaporation drying machine at a high speed. It exerts strongshearing, blowing, floating and rotating effect to the materials. Therefore theraw material is granulated through centrifuging, shearing, impacting, and afriction effect. this strengthens the process of heatexchange. At the bottom of the flash evaporation drying machine, the large anddamp granule is then crushed under the action of a stirrer. Then the small granulewith less moisture is lifted by a revolving air stream, and thus drying iscompleted. This two-phase process allows for a large and fast drying capacity.

Features of the FlashEvaporation Drying Machine
1. There are many types of feeding equipment to choose from forfeeding that is continuous or static.
2. At the bottom of the flash evaporation drying machine, raw material do notcome in contact with the heat surface directly, therefore the issues ofcarbonizing or color changing are avoided.
3. There is air pressure equipment and shaft cooling equipment, so the life ofthe machinery is extended.
4. Special equipment is employed for increasing the amount of hot air.
5. There are rotational flow pieces inside the flash evaporation drying machinedrying chamber. They are used to control the moisture and granulation of rawmaterial.
6. High efficiency is achieved due to the speed of the circulation inside thedrying chamber.

Technical Parameters of the Flash Evaporation DryingMachine

Note
1. The evaporated amount of moisture is calculated when the incomingtemperature is 200°C and theoutgoing temperature is 80°C.
2. Customized models of the flash evaporation drying machine are alsoavailable.
3. The occupied area will vary based on different environments.
