Inflated food, also known as extruded food, spray burst food, lightweight food, etc., is a new type of food developed internationally in recent years. It is cereals, beans, potatoes, vegetables and other raw materials, by the puffing equipment processing, manufacturing a wide range of varieties, exquisite appearance, nutritious, crispy and fragrant food. Therefore, the unique formation of a large class of food. Due to the production of this puffed food equipment structure is simple, easy to operate, less investment in equipment, fast returns, so the development of a very rapid, and showed great vitality.

Because of the different uses and equipment, puffed food has the following three types: First, extruded puffer, corn and potatoes as raw materials for the production of small foods; second, extruded puffer, vegetable protein as raw materials for the production of tissue-like protein food (plant meat); third, grains, beans or potatoes as raw materials, after puffing to make the staple food. In addition to the pilot production of indirect heating puffed machine, but also with fine grains puffed powder trial made of a variety of puffed food.

The puffing technology belongs to the physical processing technology, but has its own characteristics. Expansion can not only change the shape of the raw materials, state, and change the molecular structure and nature of the raw materials, and the formation of some new substances.

Principle: when the grain is placed in the puffer, with the heating, pressurization, the water in the grain is superheated state, the grain itself becomes soft, when it reaches a certain high pressure and open the puffer cover, the high pressure quickly into atmospheric pressure, which is superheated state of the grain within the water will be vaporized at once in the instantaneous strong explosion, the water molecules can be expanded by about 2,000 times, the enormous expansion pressure! Not only destroyed the grain's external form, but also pulled the grain's inner molecular structure, the insoluble long-chain starch cut short into water-soluble short-chain starch, dextrin and sugar, so the insoluble material in the puffed food is reduced, water-soluble material increased.

The biggest danger of puffed food is that it contains lead poison, which accumulates in the body and is difficult to be discharged. When the lead content in the blood is high, it will affect the nervous system, cardiovascular system, digestive system and hematopoietic system, resulting in mental dullness, anorexia, anemia, vomiting and other symptoms. The first thing you need to do is to get your hands on some of the most popular food in the world, and then you can get your hands on some of the most popular food.
