METHOD FOR CONVECTIVE DRYING OF PASTE-LIKE MATERIALS AND INSTALLATION FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC F26B3/92 F26B17/10 

FIELD: various technological processes.

SUBSTANCE: group of inventions relates to drying and can be used for convective drying of highly moistened paste-like materials, for example sapropel, cake, sewage sludge, etc. Method for convective drying of paste-like materials consists in grinding and drying of paste-like material in a vibrating fluid bed created by blowing wet material with a drying gas, on which wet paste-like material is deposited under the action of gravity, and removal of dry material from drying zone, wherein the vibrating fluid bed is created by blowing the crushed paste-like material with a pulsating flow of drying gas at an angle to the centre of the paste-like material drying zone, which is obtained by mixing the gas heat carrier supplied under pressure and pulsating gas from combustion of combustible gas, and by means of heat exchange in vibrating fluid bed performing convective drying of crushed paste-like material wet fractions by pulsating flow of drying gas, at which wet fractions are continuously displaced by oscillating movements to the centre of the drying zone with removal of the formed moisture-containing gas under the influence of the pulsating flow of the drying gas, and the fractions as they dry under the action of gravity are deposited for unloading with a controlled capacity. Also disclosed is an apparatus for implementing the method.

EFFECT: higher efficiency of drying paste-like materials.
