The Demaco extruder is a pasta extruder built by Demaco in West Melbourne, Florida, United States. It is the first pasta extruder ever built for USDA sanitary food plants. [1] Its design allowed food producers to use an extruder directly in fresh, frozen and canning factories.
The extruder evolved from a mechanical pasta press first built in 1914. The mechanical version was replaced by a hydraulic version shortly thereafter.
Containing an auger screw and mixer, the extruder combined the functions of mixing, kneading and extruding in one machine, operations that formerly required three machines.
In the 1960s, the extruder underwent a series of changes that made it easy to sanitize and suitable for USDA food plants. These included a streamlined design with quick disassembly, and stainless steel construction with completely sealed welds. [2] Demaco engineers also designed a premixer for the extruder, which received a U.S. patent in 1975. [3] In the 1980s, the Demaco extruder became automated with PLC controls.
The DEMACO extruder is used to make a wide range of products, including pasta and cereal. [4]
An innovative use of the extruder was feeding a can-filling machine for canned products. [2] [4] Demaco extruders also feed ravioli machines to make canned ravioli products. The U.S. Chinese-food company Chun King used one for the production of egg rolls.
Pasta is a type of food typically made from an unleavened dough of wheat flour mixed with water or eggs, and formed into sheets or other shapes, then cooked by boiling or baking. Rice flour, or legumes such as beans or lentils, are sometimes used in place of wheat flour to yield a different taste and texture, or as a gluten-free alternative. Pasta is a staple food of Italian cuisine.
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible.
A can opener or tin opener is a mechanical device used to open metal tin cans. Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States. These early openers were basically variations of a knife, though the 1855 design continues to be produced.
Ravioli are a type of pasta comprising a filling enveloped in thin pasta dough. Usually served in broth or with a sauce, they originated as a traditional food in Italian cuisine. Ravioli are commonly square, though other forms are also used, including circular and semi-circular (mezzelune).
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process.
Chef Boyardee is an American brand of canned pasta products sold internationally by Conagra Brands. The company was founded by Italian immigrant Ettore Boiardi in Milton, Pennsylvania, U.S., in 1928.
Franco-American is a brand name of the Campbell Soup Company. Founded by Alphonse Biardot as Franco-American Food Company, it sells gravy and condensed soups.
SpaghettiOs is an American brand of canned ring-shaped pasta in tomato sauce. It is marketed to parents as "less messy" than regular spaghetti. More than 150 million cans of SpaghettiOs are sold each year. They are sold in tomato sauce and with additions including meatballs, pieces of processed meat resembling hot dog slices, beef-filled ravioli, and calcium-fortified spaghetti.
Clarence Birdseye was an American inventor, entrepreneur, and naturalist, considered the founder of the modern frozen food industry. He founded the frozen food company Birds Eye. Among his inventions during his career was the double belt freezer.
Continuous production is a flow production method used to manufacture, produce, or process materials without interruption. Continuous production is called a continuous process or a continuous flow process because the materials, either dry bulk or fluids that are being processed are continuously in motion, undergoing chemical reactions or subject to mechanical or heat treatment. Continuous processing is contrasted with batch production.
KitchenAid is an American home appliance brand owned by Whirlpool Corporation. The company was started in 1919 by The Hobart Manufacturing Company to produce stand mixers; the "H-5" was the first model introduced. The company faced competition as rivals moved into this emerging market, and introduced its trademarked silhouette in the 1930s with the model "K", the work of designer Egmont Arens. The brand's stand mixers have changed little in design since, and attachments from the model "K" onwards are compatible with the modern machines.
Israeli couscous – sometimes called pearl couscous – is toasted pasta in tiny balls, developed in Israel in the 1950s when rice was scarce due to austerity in Israel. Despite its name in English, it is not a type of couscous.
The United States is the largest grower of commercial crops that have been genetically engineered in the world, but not without domestic and international opposition.
Campbell Soup Company, doing business as Campbell's, is an American company, most closely associated with its flagship canned soup products; however through mergers and acquisitions, it has grown to become one of the largest processed food companies in the United States. with a wide variety of products under its flagship Campbell's brand as well as other brands including Pepperidge Farm, Snyder's of Hanover, V8, and Swanson. With its namesake brand Campbell's produces soups and other canned foods, baked goods, beverages, and snacks. It is headquartered in Camden, New Jersey.
Manufactured feeds are an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish. The feeds, in the form of granules or pellets, provide the nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential.
The history of USDA nutrition guidelines includes over 100 years of nutrition advice promulgated by the USDA. The guidelines have been updated over time, to adopt new scientific findings and new public health marketing techniques. The current guidelines are the Dietary Guidelines for Americans 2015–2020. been criticized as not accurately representing scientific information about optimal nutrition, and as being overly influenced by the agricultural industries the USDA promotes.
Demaco was founded in 1914 making it the oldest pasta equipment manufacturer in the United States and the only one that makes industrial capacity machines in America. In the 1960s, Demaco pioneered the sanitary extruder for washdown food plants.

The core technologies of the Group are in the field of mechanical and thermal process engineering.
Extrusion in food processing consists of forcing soft mixed ingredients through an opening in a perforated plate or die designed to produce the required shape. The extruded food is then cut to a specific size by blades. The machine which forces the mix through the die is an extruder, and the mix is known as the extrudate. The extruder is typically a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die.
Pasta processing is the process in which wheat semolina or flour is mixed with water and the dough is extruded to a specific shape, dried and packaged.
