Snack Extrusion Machine

With the continuous enhancement of people’s awareness of health and health care, the demand for nutrition is also constantly emerging. The snack extrusion machine produced by Leader microwave equipment company can deeply process grain, beans, potatoes and other agricultural products, and add plant composite powder needed by human beings to ordinary starch raw materials. On the one hand, it can greatly increase the content of nutrients in food, at the same time, it can also improve the physical and chemical properties and physiological functions of the products. Storage performance and food flavor.

The characteristics of the snack extruder:

1.The extrusion and expansion belongs to the food texture adjustment technology, and the snack extrusion machine can change the nutrient content of the carbohydrate, the protein and the amino acid, the fat and the vitamin in the food raw material so as to meet the different needs of people for nutrition.

2.China is rich in land and grain resources, and there are many kinds of grain resources. The composite powder prepared by different plant raw materials will make people have more selectivity to puffed food.

3.The natural protein, fat, carbohydrate, vitamin, mineral and dietary fiber contained in the plant composite powder processed by snack expansion machine are in accordance with the reasonable proportion of human intake and have high utilization value.

4.The snack extrusion device has a wide variety of products, the process is simple, the production efficiency is high, the product quality is good, and the puffed food with various flavors can be produced by using the low-price crude raw materials, so that the process has the advantages of low cost, high yield and no “three wastes”-free whole process automation and continuous production effect.

Characteristics of single-screw snack extrusion machine:

The structure of single screw extrusion machine is relatively simple and the price is low. its disadvantage is that the scope of application is limited, which is mainly used for materials with high starch content, and there are still some difficulties in the production of materials with high moisture and high oil content.

The twin-screw extrusion bulking machine has many advantages. Even if the material with high water content and high oil content is not easy to generate a reverse flow, a higher pressure and a higher temperature extrusion process can be performed. Therefore, the double-screw extrusion bulking machine has the advantages of good performance, wide application range, high efficiency and good product quality, and is widely applied to the fields of food, feed, grease industry, fermentation industry and grain processing and the like.

Operating principle of snack extrusion machine:

The snack extruder comminuted, mixed and humidified the food raw materials containing a certain proportion of starch and grease, and then entered the extrusion sleeve through the feeding device. The thrust effect produced by the relative rotation of the screw and the cylinder wall in the extruder sleeve was pushed forward. Through the material calender effect and the high temperature and high pressure produced by heating, the material was mixed, cut, mixed, melted, sterilized and ripened in the extrusion sleeve. The temperature and the pressure are rapidly increased, then suddenly released to normal pressure, the shape, the internal structure and the property of the material are changed and rapidly expanded, and finally, the expanded food is made through the end-formed spray head.

The die holes of different shapes of snack extrusion machine can produce products of different shapes. Among them, a series of physical and chemical changes take place under the action of high temperature and high pressure, such as gelatinization of starch and denaturation of protein, which destroy harmful factors in some raw materials, kill a large number of bacteria and microorganisms, and even those enzymes that may cause deterioration of materials during storage are treated by this high temperature and high pressure action and expansion process. It will also lose activity, making processed food easier to store and maintain quality.

With the development of society, fast food has occupied a large market, expanded products are suitable for both old and young, some plant composite powder expanded food also has health care function, so snack extrusion machine, leisure food making machine has a broad development prospect.
