A tomato machine can turn tomatoes into juice, paste or pulp. They come in various designs for home or commercial use, with features to remove skin and seeds. They can be electric or manual and have modular accessories. Components include a hopper, paddles, a chute, and a clamp or suction cup. Processing is done by an auger, screen or cylindrical grater. Materials used include plastic, stainless steel, and cast iron.
A tomato machine is a device used to process tomatoes, turning them into juice, paste or pulp. There are a variety of designs, some made for use on a countertop in the home and others specifically designed for use in a commercial or industrial setting. Features may vary from one tomato machine to the next, but generally include the ability to remove the skin and seeds from tomatoes as they are mashed or pressed. There are both electric and manual models, with electric versions capable of processing several bushels of tomatoes in an hour. The concept of a tomato machine is quite simple, so some devices actually have a collection of modular accessories that can allow the machine to be quickly converted into anything from a meat grinder to a juicer.
The basic components of a tomato machine include a large hopper on top that tapers into a thinner channel that leads to the area where the tomatoes are pressed. This area usually contains a set of paddles that might be spring loaded, as well as some type of sharp metal device that does the actual processing of the tomatoes. A chute leads from this area under the hopper, allowing the juice from the tomatoes to be directed into a specific container or area, although some models have more than one exit chute to allow for the different parts of the separate tomato to be divided. The machine may also have a clamp or suction cup that can stabilize it on a countertop, though large commercial machines and some electric models rely more on their weight for stability.
Inside a tomato machine, processing can be done by an auger, screen or cylindrical grater. An auger looks like an exaggerated screw with deep grooves. The tomatoes are pushed into the auger and the skin, which is thick and waxy, is separated from the flesh and juice through the pressure. A metal screen separates skins and seeds from the juice acting like a sieve while the tomatoes are pressed against the screen by strong scoops. A cylindrical grater often has small sharp holes around the outside that destroy the tomatoes when pressed into it, allowing the juice and pulp to exit the machine in the center of the cylinder.
Plastic, stainless steel, and cast iron can all be used to make the various parts of a tomato machine. Stainless steel is most often seen due to its resistance to stains, which can be caused by tomatoes. Cast iron can be used to make the base for the machine, the handle or other elements that must be heavy and resistant.
