Mincing machine for grinding up food

摘要

A cutter set for use in a mincing machine for grinding up of food, particularly meat, cheese and fat. The food is supplied to the cutter set by a conveyor screw. The cutter set consists of at least one rotating knife and at least one perforated disk. The rotating knife has an annular channel around the periphery thereof for facilitating a discharge of hard particles contained in the food. At least a pair of cutting blades is provided on the rotating knife and is connected by a ring having the annular channel therein. At least one of the cutting blades has a radial channel communicating with the annular channel. The channel in the cutting blade is fed from an inlet adjacent the hub thereof. An outlet opening is provided in the housing in which the cutter set is mounted and has a discharge opening communicating with the annular channel for effecting a discharge of the hard particles contained in the food and collected in the annular channel. The ground-up food products, on the other hand, are discharged in a direction parallel to the axis of rotation of the rotating knife.
