Why are meat grinders an essential part of commercial food processing equipment?

One of the most essential pieces of commercial food processing equipment is the meat grinder, used for chopping, mincing and mixing meat and fish. At home, mincing is most often done with a mincing knife, but in a butchers' shop or a food factory, using a mincing knife would be both inefficient and slow. Meat grinders are able to make short work for a high volume of meat, allowing butchers to concentrate on other tasks.

Meat grinders were invented in the nineteenth century in Germany, with a hand crank grinder. However, as time went on, grinders came to be powered by electricity. Though hand cranked grinders still exist today, they are generally used for domestic kitchens, with more powerful electric grinders being a staple of food processing equipment for commercial kitchens.

Modern electric grinders are not only used for high volume work, but can be repurposed for versatility that would otherwise require other pieces of food processing equipment. For example, with the use of attachments, grinders can be used for sausage-making and juicing, making them invaluable to the modern butcher or commercial kitchen.

Another popular additional feature for industrial meat grinders is the mixer unit. This unit can mix various types of meat (such as pork or beef) together homogeneously or with additives (such as salt or spices) prior to grinding. Without this unit, these additives have to be mixed into the meat after grinding it, which can produce a different taste or affect the appearance of the meat. For this reason, the mixer unit is a common addition to commercial food equipment and processing operations.

Meat grinders, like many other commercial processing machines for the food industry, are usually constructed from stainless steel. One reason for this is steel's sturdiness - essential in a busy kitchen, factory or meat room. However, the biggest reasons for stainless steel's popularity in this industry is how easy it is to clean and maintain, with a non-porous surface that can easily be wiped clean of any juice or residue from the meat or fish placed in the grinder.

Grinders are typically disassembled for a complete clean, with hot soapy water to remove any oil or remnants of meat. Spare parts are stored with a thin layer of oil (typically food-grade mineral oil) coated over them - this prevents rust and corrosion while they are not in use. As with any piece of food equipment, regular cleaning is essential to maintain the high standards of hygiene necessary for any commercial workplace in which food is prepared. Regular cleaning and maintenance also ensures that the machines live longer - with regular maintenance, some machines can go for decades without needing to be replaced, though some meat rooms may opt for a newer model with more functionality anyway.

Meat grinders are an essential part of commercial food processing equipment, making it possible to run a high-volume operation with higher profit margins and more versatile stock options. Having come a long way from their origins as hand-cranked machines in the nineteenth century, meat grinders are now found in every meat room and food factory there is.
