DEVICE PARTICULARLY FOR PROCESSING FOODSTUFFS AS WELL AS WORKING METHOD FOR OPERATING ROLLING-DRUM PROCESSING APPARATUSES

摘要

A drum for the kneading of food pieces or the blending of food constituents is mounted on an inclined axis and there are spiral flights 24 along the side wall of the drum. Charging and discharging the drum is effected through an open end and the drum includes a door 23 for airtight sealing of the drum. A vacuum can be drawn via a pipe 46 to the drum for different types of processing or there can be pressure applied. A kneading action can be applied to massaging or tumbling meat chunks, and treatment liquids can be added to the drum and/or the food pieces for processing. Steam heating can be supplied. A door-operating mechanism for a door for the mouth of the rotatable drum includes a moveable arm 47 hingedly mounted with anchoring means 48 on the side of the frame of the drum. The arm may be coupled by clamps for connection with a stub shaft extending from the door. When the door is closed on the mouth of the drum, the clamps are disengaged from the stub shaft so that the door is secured, under vacuum pressure within the drum, as an integral part of the rotating drum. Force is thus avoided on the hinged, moveable arm, and stub shaft of the door and door-operating mechanism.
