Disassembled hand-powered grinder
A meat grinder or meat mincer is a kitchen appliance for grinding, fine mincing or mixing raw or cooked meat, fish, vegetables or similar food. It replaces tools like the mincing knife for example which has been used to produce minced meat, filling etc. The producer puts the warse minced food into a funnel, which is placed on the top of the grinder. From there the material goes on a horizontal screw conveyor. This screw conveyor, that can be powered by a hand wheel or an electric engine, squashes and mixes the food partially. At the end of the screw conveyor there is a knife installed directly in front of the fixed hole plate. At this opening the minced meat comes out of the machine. The fineness of the meat depends on the size of the holes of the plate.
By changing the hole plate it is also possible to produce breadcrumbs or fill sausages. After the drop from the retainer, it is possible to change the hole plate. When removing the fixing screw the grinder can be disassemble completely for cleaning. Beside the manaually operated or engine powered grinders, there do also exist some tools for the butchery (table- or shop-grinders for example) and for the food industry. This large machines are able to produce several tons per hour. For these machines the Typ-C-norm DIN EN 12331 "machines for the food industrie - butchery grinders - safety- and hygienerequiements" from 2004-5 with the change from 2007-A2, is apllied.
Mixer unit
A basic optional feature for larger grinders is the mixer unit. With this unit can be mixed different kinds of meat(for example beef or pork) with each other homogeneously and/or can be mixed the meat with additives, like salt or spices, before grinding it. Without such a mixer unit have to be mixed the additives into the meat after grinding it. This affects adversely the sensory and visual quality of most products.
Frozen meat grinder
Frozen meat grinders can process frozen blocks of meat, bacon and MDM up to –25 °C. The frozen blocks can amount from 900x500x150 mm to 900x500x200 mm, the power can applies from 8.000 kg to 12.000 kg. By the regular cutting the chopped meat can be processed through mixers and grinders, which reach an optimal addition in the cutter as well as a protection of the cutter and knifes.
There are 2 different drive forms, a single rev-drive, which is ideal to grind frozen meat blocks, and a two rev-drive, which promises higher power by the application of a special meat worm.
The first cut takes place in the worm, who peels with his long pulled, sharpen meander/bend approximately 8 cm from the frozen meat and then to pass on for the next cut in the cutting set . The lock protection prevents possible mechanical damages in too high burden/load, for example by a foreign body.
