Choose food screw extruder according to your needs

Features of Single Twin Screw Snack Extruder:

The structure of the single-screw extruder is relatively simple and the price is low. Its disadvantage is that the scope of application is limited, and it is mainly used for materials with high starch content. There are still certain difficulties in the production of materials with high water content and high oil content. In addition, the process parameters are difficult to control, the machine is not easy to clean, the product form is poor and the output is small.

Twin-screw extrusion extruder has many advantages. Even materials with high water content and high oil content are not easy to produce reverse flow, and can be extruded at higher pressure and higher temperature. Therefore, the twin-screw extruder is widely used in the fields of food, feed, oil industry, fermentation industry and grain processing because of its good performance, wide application range, high efficiency and good product quality.

How the snack extruder works:

Snack extruder is to grind, mix and adjust the humidity of the food raw materials containing a certain proportion of starch and oil, and then enter the extrusion sleeve through the feeding device, and the thrust generated by the relative rotation of the screw and the cylinder wall in the extruder sleeve The effect is pushed forward, through the high temperature and high pressure generated by the calendering effect of the material and heating, the material is mixed, sheared, kneaded, melted, sterilized and matured in the extrusion sleeve, and the temperature and pressure rise sharply , and then suddenly released to normal pressure, the shape, internal structure and properties of the material change and expand rapidly, and finally it is made into puffed food through the end forming nozzle.

Die holes of different shapes in the snack extrusion machine can produce products of different shapes. The material undergoes a series of physical and chemical changes under the action of high temperature and high pressure, such as starch gelatinization and protein denaturation, which destroys harmful factors in some raw materials, kills a large number of bacteria and microorganisms, and even those that may Various enzymes that cause material deterioration will also lose their activity after being processed by this high temperature and high pressure and puffing process, making the processed food easier to store and maintain quality.

With the development of society, fast-moving food has occupied a large market. Puffed products are suitable for all ages. Some plant compound powder puffed foods also have health care functions. Therefore, snack extrusion machines and snack food production machines have broad development prospects. .
