APPARATUS FOR PROCESSING GRAIN MATERIAL BY FLUID Russian patent published in 2016 - IPC B01J8/00 B01J3/04 

FIELD: technological processes.

SUBSTANCE: invention relates to apparatus for processing grain material by fluid under pressure and can be used for desorption of various components of adsorbents, for example from activated carbon in technological processes of extraction of precious metals. Apparatus comprises working chamber with loading and unloading holes, fluid feed and discharge branch pipes arranged in opposite ends of working chamber, and loading and unloading mechanisms in upper and lower parts of working chamber, in form of interconnected cylindrical dosing units, separated by longitudinal plates with possibility of axial synchronous movement, dispensers are arranged in deformed elastic tori filled with fluid or gas under pressure, one of tori is stepped and larger diameter towards working chamber, wherein each torus is equipped with feeder for supply of liquid or gas.

EFFECT: simplified design and higher reliability, as well as a continuous process of treatment.
