The extrusion technology in puffs in food the application to be also more widespread.In extruder pasta class food moisture content because is in under the pressure to become the liquid state,Then when squeezes out from the template hole, the superheat moisture content suddenly is in under the atmospheric pressure, the pressure reduces suddenly,The pressure reduces suddenly, the moisture evaporation steam, produces promotes and the inflation, like this causes this product to have one kind of low density light quality condition. The extrusion technology took in the food industry an extremely important technology obtains a bigger development,Modern food industrial used screw rod extruder have the mix, the fusion, the steam boiling, the modification reflected, the quenching and tempering, the organization, the formation, puff and so on many kinds of functions,manifests is advantageous to the automatic control, is advantageous for produces a different product nimbly as well as the energy conservation, the festival labor force, saves produces merits and so on location. The single screw extruder structure simple, easy to process the manufacture, the cost is inexpensive, widely uses in processing each kind to puff snack food,In the design designs a single screw rod extru
