IMPROVEMENT OF THE EXISTING INTERNAL HEAT EXCHANGE PROCESS IN MODERN BELT DRYERS

Abstract

Different designs of dryers have been created on the basis of the general rules of providing external energy during heat treatment of dispersed materials, which have their own advantages and disadvantages. One of the promising methods of accelerating the drying process of dispersed materials is the use of belt dryers. One of the main advantages of devices that work in this way, called belt dryers, is the simplicity of the mechanical devices that move inside them, which increases the accuracy of the dryer. The small dimensions allow us to save a lot of rare stainless steel used for their production. Due to the heat applied to the belt dryers, the dispersed material undergoes intensive thermal processing, and its processing is fast. In this way, the contact time of the dispersed material and the heating surface is formed, and the efficiency of the contact drying process increases many times.
