Production
Stage 6
Drying Stage
This is our favorite stage. During this stage, the product gets its dry free-flowing structure. It becomes commercially successful, convenient for the transportation and practical usage. Fluidized-bed furnaces where the product is dried work according to the following principle: dry warm air goes from the bottom under the pressure, and rarefied air is accumulated in the upper part of the furnace. Thus cysts are permanently stirred up with the help of ascending air flows.
