How Is Extruded Food Made
The extrusion and puffing food production equipment is a very mature product of our company, with years of research and development experience and technology, and continuous technological innovation. We can customize different design solutions according to the needs of different customers, achieving high standards of precision. Extrusion machinery can mainly produce various types of extruded food, such as sandwich rice fruit, wheat cake, doughnut, cocoa dessert, Snow pea, McChicken pieces, etc.
The main working principle of extrusion and extrusion machinery is to feed the mixed raw materials into the screw extrusion chamber of the extrusion and extrusion equipment. The space volume of the extrusion chamber gradually decreases along the direction of material advancement, and the expansion pressure on the material gradually increases. At the same time, the movement of the material in the extrusion chamber is accompanied by strong shear, kneading, and friction, causing the internal pressure and temperature to continuously increase. The organizational structure of the material changes, causing further gelatinization of starch, protein denaturation, and damage to crude fibers. High temperature and high pressure cause the material to come out of the discharge port, and its pressure is suddenly released in an instant, causing partial flashing of water. After cooling, the material presents a loose and porous structure, and the expanded material appears in the form of clumps, flocs, or coarse chips. The extruded product is then shaped into a specified size or shape through a shaping mechanism.
Our company has developed various models of extrusion and expansion machinery, mainly divided into two categories: single screw hosts and double screw hosts. The single screw extruder mainly produces billets and List of fried dough foods, and the products produced need to be fried and expanded twice. The twin screw host is a direct expansion type host, without the need for secondary expansion. Each type of extrusion expansion host has different production and size models.
