Abstract

Device for mixing solid particles of dry ice and the flow of gaseous medium including a feeding element (2) rotatively placed within the fixed housing (1) having openings (12, 13) for the flow of gaseous medium and/or the flow of gaseous medium with solid particles. Between the fixed housing (1) and rotatively placed feeding element (2) the immovable elastic membrane (3) is placed. The fixed housing (1) is at the side of the elastic membrane (3) provided by at least one sealed pressure chamber (14) connected with the opening (13) for the flow of gaseous medium and/or the opening (12) for the flow of gaseous medium with solid particles.

Claims
