FEEDER-GRANULATOR FOR VACUUM-SUBLIMATION DRYER Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: conveyer 1 is made up as plate baffles defining rectangular cells. Longitudinal and lateral baffles are pivotally interconnected to permit rotation of the baffles. The bottoms of the cells are mounted for permitting reciprocation over guides of longitudinal baffles and is provided with expansion springs. Driving drum 2 of conveyor 1 is constructed as a gear wheel. The top edges of teeth of the gear wheel are in contact with movable bottoms of cells of conveyor 1 when it runs over driving drum 2. Device 4 for supplying a product to the conveyer is additionally provided with sealing rollers 10 which are mounted from the side of the inlet and outlet of conveyer 1 and are in contact with the other rollers 9. The diameter of the sealing rollers is no less than the twice distance between the adjacent lateral baffles of conveyer 1. Conveyer 1 is provided with roller 18 in the direction of moving frozen product. The roller underlies the top branch of conveyer 1 and can be set in rotation by way of guide 19 fixed above the top branch of the conveyer. EFFECT: improved design. 3 cl, 4 dwg
