Drying Process

Worldwide, the drying units consume between 13-15 % of the total quantity of energy produced. That is why, the correct choice of the type of equipment and the optimum counted drying process can considerably decrease the product cost price. Because of the grate variety of materials subjected to drying, the drying equipment is projected for every given product. The type of drying equipment depends on the physical condition of the material processed, on the thermal, structural-mechanical and capillary characteristics of the drying objects, and on some other factors. The construction of drying equipment has a grate influence upon process energy consumption, and there from upon processed product cost price. In world practice, a dozen of main types of drying equipment are used, the sub-types being tens and hundreds. When selecting the concrete structure of drying equipment, we are lead by a number of criteria, the main being three: Detailed study of the processed material as a drying object in order to minimize the amount of energy consumed per unit of processed product and maximum good quality of the final product

Detailed study of the processed material as a drying object

A minimum quantity of energy consumed per unit of product processed;

End product with a maximum high quality;
