②Inflating snacks with colorful and special taste, such as shrimp chips, shrimp ball, and so on.

③Match the additional equipments, the line can produce various kinds of the core filling food and the inflated biscuits. Adopting the twice-extruding crafts put the materials like yolk powder, milk powder, sesame, chocolate and others into the materials to make the core food, owning the special taste.

④ By the riding of simple crafts, low cost, and efficient use of the materials, our equipments are widely used in the field of the food, chemical industry, forage, brew, and pharmacy, etc.

3. The Meaning of the type:

SLG  means type of  Double  Screws ;85 means the diameter of  screws; Ⅲ means the generation.

4. Technological Principle:

  The key and character of TSE is to adopt the extruding and inflating technology, which is the most popular abroad and domestic market, and the latest high-tech. The grain will inflate, the starch increase the water-solubility, so as to be digested.

As well as everyone knows, the main component of the grains is starch, which is not adept to dissolve into the water, or be effected by the enzyme. Only when the raw rice and flour are dissolved & inflated in the hot water, and make the starch “α”,can be digested. But after cooking, they will become solid and tasteless in the normal or low temperature, which is always called “life-back of the starch”. In this condition, this is “βStarch”. Extruding & inflating technology can make the raw starch mushy, turn into the “αstarch”, enable keepαstructure stable, avoid the life-back of the starch and keep perfect taste.

  During the process of inflation, together with being pulled toward by two screws, material in the sealed metal canister, will stay at high temperature(150~200℃)because of the machine’s oppression, interior cutting force, and heat outside. The high pressure(above10kg/cm²),produced by the volume and the high temperature, makes the materials in the sealed condition gelatinous, then get a lot of the heat energy and change original the physical and chemical attribute, thus make the starchα. When the materials extruded from the die-head, increase their disorder degree in the normal condition and the pressure, which can not only make the materials inflated to promote the enzyme, buy also decompounds the starch and protein to increase solubility, e.g. after     

inflating, part of the corn starch are decompounded into dextrin and sugar, furthermore, more than 80% starch become ‘α’starch, thus be tasteful.

   In the high temperature and pressure, the starch chain suffers damage and keeps quality duration. During inflating, protein is decompounded into amino acid reaching 70%, while digest rate upraises.
