METHOD FOR PROCESSING HEAT-SENSITIVE MATERIALS IN A VORTEX CHAMBER Russian patent published in 2021 - IPC F26B3/10 F26B17/10 

FIELD: materials processing.

SUBSTANCE: invention relates to the field of materials processing, in particular to a method for processing heat-sensitive materials in a vortex chamber, and can be used for drying, grinding, heat treatment and simultaneous fractionation of such heat-sensitive materials as grass, straw, medicinal plant raw materials, vegetables and other materials or a mixture of various plant materials. The invention can also be used for processing agricultural waste, in particular poultry manure, horse or cow manure, into safe organic materials, such as fertilizers. A method for processing heat-sensitive materials in a vortex chamber includes vertical feeding of wet material into a vortex chamber, the walls of which are made in the form of a body of revolution and which contains a rotor for mechanical grinding of the incoming material and its involvement in the vortex flow of drying gas entering the chamber through the inlet tangential channel, at which time this vortex flow first dries the material, and then removes it from the chamber in the form of a gas suspension through the gas removal system. The vortex chamber is made with the ability to change its volume, wherein the upper end and lower end walls of the chamber are made in the form of bodies of revolution, and the side wall connecting them is in the form of a lateral surface of a straight circular cylinder, while additional holes can be made on the outer surface of the side wall and/or on the lower end wall of the chamber for extraction recycled material.

EFFECT: materials processing improvement.
