snack extruder-manufacture,factory,supplier from China

When using a twin-screw extruder, the twin-screw extruder needs to install the device correctly, so that it can save energy and time during production.The twin-screw extruder is fully automated from batching, extrusion, puffing, molding, core sandwiching, cutting, spraying to finished products at one time. The production line has the characteristics of many optional models, flexible equipment configuration, wide range of raw materials, many types of products, and simple operation.

Puffed snack food is a kind of brittle food with delicate taste and rich taste. With the improvement of Chinese living standard and the change of consumption concept, all kinds of grain puffed food as a convenient, quick, nutritious leisure small snack, quickly enter many households. Leisure food production line has many optional models, flexible equipment configuration, a wide range of raw materials, a wide range of product types, simple operation and so on.

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.

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.

Series double screw extruder introduction:1, mainly by the feeding system, extrusion system, rotary cutting system, heating system, lubrication system, control system.2, extruder feeding system, main drive system, rotary cutting system all adopt frequency control, strong power, smooth operation, power saving.3, automatic lubrication, forced cooling, to ensure the safe operation of the extruder and prolong the life.4, screw alloy material, through special processing, high strength, wear resistance, increase the service life.5, according to different products, with different structure and length

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.

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 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.

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.

Working Principle of Twin Screw ExtrusionAfter a certain amount of pulverization, the material with a certain water content is fed into the extruder cavity, so that the material will undergo mixing, shearing, A series of complex continuous processes such as melting, curing and sterilization. Because there is a certain air pressure difference inside and outside the barrel, the moment the material is extruded, the external pressure it is subjected to is reduced to normal pressure, so that the material is instantly puffed.
