The history of the food extruder

Extruder is the key of extruding technology. Extrusion processing technology as an economical and practical new processing method is widely used in food production, and has been rapidly developed. Extrusion processing mainly by an extruder step to complete the raw material mixing, curing, crushing, sterilization, pre-drying, molding and other processes, to make puffed, organized products or not puffed products. By simply changing the extrusion die, you can easily change the shape of the product.

The patent for the first screw extruder in the world was obtained by Gray of England in 1879, mainly for the rubber and plastic industry. In the 2030s, the first single screw extruder for grain processing appeared, and it began to be used to produce puffed corn. During World War II, the Japanese used the twin-screw extruder to produce compressed military rations. In the 1960s, twin-screw extruders began to appear and were used in food processing. In March 1980, Beijing Institute of Food Research imitatedthe first self-heating PJ-1 grain extruder. In 1982, Wuxi University of Light Industry introduced a BC-45 twin-screw extruder from Clextral Company in France, and began to study the extruder processing technology. At the same time, many domestic manufacturers have also introduced advanced extrusion equipment from major companies in the world. International representative extruder production enterprises in addition to France Clextral Company, the United States Wenger Company, Germany WP Company, Italy MAP company, Japan's Enubi Food Co., LTD., Switzerland's Buchcler company and so on. In the introduction of foreign equipment at the same time, many domestic manufacturers have produced different types of extrusion equipment, in which the single screw equipment is the majority.

Screw extruder used in food production has the characteristics of simple process, one machine multi-energy, continuous production, high efficiency, low energy consumption, less investment, fast results. The food produced is delicate in taste, easy to digest and absorb, less loss of nutrients, long storage time, not easy to produce "regenerative" phenomenon, easy to eat. At present, extrusion technology has become one of the most commonly used extruded food production technology. Research and development of extruder is also imperative.
