METHOD FOR CLEANING SOLID CRYOGENIC MATTER PARTICLES AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC B24C3/06 B24C1/00 B02C18/08 

FIELD: surface cleaning.

SUBSTANCE: invention relates to the cleaning of surfaces from contamination by particles of solid cryogenic substance. The device contains a housing, a rotating knife matrix, a stationary knife matrix fixed on the housing, and a flat flow matrix fixed in the housing. The rotating knife matrix is located between the installation plane of the upper stationary knife matrix and the installation plane of the flat flow matrix. The rotating knife matrix is made with the possibility of cutting granules of the solid cryogenic substance in the plane of contact of the stationary knife matrix and the rotating knife matrix and/or in the plane of contact of the flat flow matrix and the rotating knife matrix. The flat flow matrix is located at a distance from the rotating matrix that determines the maximum size of the cutting fraction and is made with many through holes.

EFFECT: as a result, the reliability of the device increases, as well as the performance of the cleaning process.
