IMPROVING THE DESIGN OF THE UNIT FOR DRYING POLYDISPERSE MATERIALS

Abstract

In the production of many food products, drying is usually a mandatory operation and it is a fairly energy-intensive technological stage of the process. The quality of the product depends on a large extent on the hardware and technological design and drying mode.

This article discusses a useful model for drying polydisperse materials, which can be used in food, chemical, pharmaceutical and other industries. The unit can be used, in particular, for drying thermolabile materials for which prolonged exposure to high temperatures is undesirable.

The article describes the design and operating principle of the unit for drying polydisperse materials. The proposed technical solution is considered, which provides a reduction in the resistance of the layer of the material to be dried, a reduction in the pressure loss of the drying agent, and the creation of a soft hydrodynamic regime.
