snack extruder machine-manufacture,factory,supplier from China

For extruder equipment, the model specifications of extruder equipment are classified according to the diameter of the screw. For the sake of explanation, plastic is used as an example below, but the same is true for food extruders.That is to say, the screw diameter of the extruder equipment is the model specification of the extruder equipment. For example, the screw diameter of the 90-type extruder equipment is 90mm.

There is only one screw in the barrel of the single screw extruder, it is by the friction of the screw and the barrel of the material to transport materials and form a certain pressure. In general, the friction coefficient between the material and the barrel is greater than that between the material and the screw. Otherwise, the material will be wrapped in the screw together to rotate and not play the role of forward propulsion.Screw is divided into three sections: feeding (feeding) conveying section, compression melting section, metering homogenization section.

The advantages of our twin screw extruder:1. Double screw snack extruder adopts side forced feeding technology, which increases the integrity of the material and greatly increases the output. The position and shape of the feed port also have a great influence on the feed efficiency. Under the same parameters, the feed area increases and the output increases. For the same inlet area, rectangular section has greater feed efficiency than circular section. The use of side twin screw feed is also based on such a consideration.2. Twin screw extruder has strong self-cleaning ability.

The screw extruder was first used in the plastics industry, and its theoretical research started earlier, forming a variety of mathematical models used to describe the basic principles of flow and heat transfer in the extrusion process, using these models to achieve accurate extrusion machine simulation Design. The application of extrusion technology in the food industry is slightly later than that in the plastics industry, which is mainly due to the complexity of food raw materials.

Twin screw extruder is developed on the basis of single screw extruder. Two screws are placed side by side in the barrel of the twin screw extruder. According to the meshing degree of the two screws can be divided into mutual meshing type and non-meshing type. According to the rotation direction of the two screw shafts, it can be divided into reverse rotation type and co-rotation type.(1) meshing twin screw: Because the meshing gap of the meshing screw is very small, the material has the ability of forced conveying, not easy to produce backflow, leakage phenomenon.

Feed extruder is a single screw extruder. Mainly used for food puffing, livestock feed or used for puffing single raw materials, but also as a plant oil and drinking wine production of raw materials in the pre-place. Twin-screw extruding extruder, mainly used for the production and processing of high-grade aquatic products, pet materials, especially the processing of viscous materials.What are its characteristics?1.

The extruder has the functions of compression, mixing, kneading, melting, puffing and molding. The cavity of the extruder can be divided into 3-5 zones. Each zone can be heated by steam or electricity, or by extrusion friction, so as to achieve the purpose of cooking the material. Under the action of high temperature and high pressure in the cavity, the starch Gelatinization, protein denaturation. When the material passes through each zone of the extruder cavity, soluble flavor substances and pigments can be injected into the material through the cavity under high pressure.

DRIED FOOD IN SNACK FOODNowadays, when we walk into shopping malls and supermarkets, we will find potato chips, shrimp sticks, snow cakes, preserved fruits, dried fruits, fish fillets, dried meat and other kinds of snack foods with exquisite packaging, fashion and unique taste. With the improvement of people's living standards, snack food has quietly become the new favorite of consumption, and various dried snack foods are becoming more and more common in the market.

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.

　　The puff snack extruder has two pairs of screws that mesh with each other and rotate in the same direction. They jointly play the roles of conveying, friction extrusion and heating. The materials are input by the principle of positive displacement for forced conveying, and pressure backflow is rarely formed.　　Thus, the problem in this respect on the single screw extrusion extruder is better solved, and strong conveying. puff snake extruder integrates compression, mixing, mixing, shearing, melting, sterilization, expansion, molding and other functions, and is completed in a very short time.
