What food equipment should be used to make leisure food that can be directly puffed

Direct puffed snack food is a very widely consumed food, they are used by the type of extruder characteristics known as corn fruit. In recent years, this type of food is called direct puffed food. Typically, direct puffing foods are produced on high shear cooking extruders. This type of product is named for the direct puffing that occurs when the product comes out of the extruder template and requires no further processing other than drying. Some examples of puffed snack foods are taco (baked or fried), onion rings, potato chips, and more recently, three-dimensional snack foods.

Direct puffing leisure snacks food puffing process is produced by heating materials to make the temperature more than 100℃, in the extruder dough water is liquid because the dough is under pressure, and then the dough from the template extrusion extrusion machine, superheated water suddenly under atmospheric pressure, pressure rapidly reduced, water evaporation into water vapor, The resulting stretched and expanded starch matrix gives the product a low density and light texture, with the overall density falling within the range of 50 to 160g/L. The shape and size of such products are determined by the formwork design, the viscoelastic properties of the extrusions, and the cutting method. The refrigeration equipment used to produce such products may be simple jacketed extruders or twin-screw extruders. Jacketed extruders are used to produce products such as corn rolls and corn extruders. More complex single screw extruders and twin screw extruders should be used if the ingredients are more demanding. Productivity is generally: jacket-type extruder 50 ~ 200kg/h, single screw extruder with longer sleeve 100 ~ 600kg/h, twin screw extruder 150 ~ 1000kg/h.
