METHOD AND DEVICE FOR BLENDING FOOD-STUFF Russian patent published in 1995 - IPC

FIELD: food industry. SUBSTANCE: food-stuff is fed into the drum, which is mounted for rotation and has spiral blades onto its internal surface. Foods are blended continuously inside the drum during rotation to improve better contact of different food products. The drum is provided with means for feeding and removing heat-transfer agent. Drum also has hollow spiral-shaped blades for heat-transfer agent circulation. Moreover, specific temperature is sustained during process of mixing due to close contact of the blades with food products. The drum is mounted onto the frame for rotation and has a drive. Device for mixing is provided with temperature control unit, which is necessary for keeping specific temperature. Spiral-shaped blades are connected with temperature control unit. The blades are hollow and are made of two communicating sections at least for heat-transfer agent circulation. One section is used for monotonous feeding of the heat-transfer agent, and the other one for getting agent back. EFFECT: improved efficiency of operation. 2 cl, 3 cl, 6 dwg
