The development of puffing snack machinery.
When the American, Ward, applied for the first patent about puffing in 1856, he must never thought the puffing technology could be used in so many fields after a century like plastic, feed, food, chemical, pharmaceutical, oil processing and so on. He would never thought the extruding machine be developed twin-screw from single-screw. What’s more, the twin-screw extruder also includes the non intermeshing co rating screw, the relative rotation of non engagement scew , the intermeshing co rating screw, the relative rotation of engagement. More and more people learned the magical of extruding machine. The price of more and more food materials rise after extruding.
Although our puffing food has a long time, but the development of extrusion machinery is relative lag. We began the research of puffing technology and puffing food until the end of 1970s.
At the begin of 1980s, puffed leisure food began to appear and enriched Chinese traditional leisure food, which mainly includes peanut, biscuit, candy and sunflower seeds. At the meantime, it led a number of emerging enterprises’ establishing and growing. In 1990s, with the development of market, the maturity of domestic puffing technology as well as the coming of international puffing enterprise, the domestic puffing food enterprises began the industrialization road of development. Entering 21st century, more puffing food ,made by many kinds of raw materials appear and enrich the food market and the life of people.
