meat grinder
A meat grinder (in Austria, meat machine or Faschiermaschine ), also briefly Wolf or rotary Wolf, serves the fine crushing or grinding and blending (fachsprachlich "Wolfen" and "mincing") of raw or cooked meat or fish , cooked vegetables and similar foods. He replaced chopping knife and other kitchen tools for the production of minced (ground meat, minced meat, Haschiertem, Mett), meat , fillings and others.
functionality
The coarsely chopped food is placed in a funnel and is placed on a horizontal screw conveyor driven by a hand crank or an electric motor , which also squeezes and partially blends it. In the simplest case, at the end of the screw there is a knife disk that is firmly connected to its axis and therefore also rotating, immediately in front of a stationary perforated disk , from which the more or less finely ground mass emerges, depending on the size of the holes.
After removing the fastening ring, the perforated disc can be replaced; If the fastening screw on the crank is also removed, the device can be completely dismantled for cleaning.
By exchanging the attachment, breadcrumbs can also be produced or sausages filled ( sausage filling attachment ). It is also possible to make cookies ( shortbread cookies ) with suitable attachments . The cookie dough has an elongated flat or star-shaped shape.
Higher-quality devices have a three-part cutting set with a fixed pre-cutter in front of the knife and perforated disc. This means that even sinewy meat can be processed reliably without the risk of unshredded tendons wrapping around the snail. Machines with a five-part cutting set have an additional perforated disk after the first knife and a second knife.
Meat grinder (butcher machine)
In addition to hand or motorized meat grinders for the household, there are also devices for the butcher's shop (table grinder, shop grinder) and for the food industry . These large meat processing machines can process up to several tons per hour. For these machines, the Machinery Directive with the Type-C standard DIN EN 12331 Food Machines - Grinders - Safety and Hygiene Requirements from 2004-5, with changes from 2007-A2, applies.
In professional grinders there is a fixed disc called a pre-cutter in front of the knife, so that the knife has two cutting surfaces in front of and behind the knife. For particularly fine grains, a second knife is inserted after the first perforated disk and then a perforated disk with a smaller opening. Spacer rings of different widths press the cutting tools with the fastening nut into the worm gear. The openings in the disc determine the grain size of the material to be cut. Specially shaped sleeves also enable the partial separation of solid components (pieces of bone, cartilage and tendons), so that the mincing process also improves the quality of the cut material.
cooling
Due to the high hygiene requirements, meat grinders with cooling are now also on the market; in addition to the motor, the devices also have a compressor for cooling.
Mixing device
An optional additional device for larger meat grinders is the mixing device. This means that different types of meat (e.g. beef and pork) are mixed homogeneously with one another before grinding and additives such as salt and spices are mixed into the raw meat. The shredding process is then started.
Without a mixing device, the additives have to be mixed into the minced meat after grinding, which has a negative effect on the sensory and visual quality of most products.
