snack extruder-manufacture,factory,supplier from China

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.

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.

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.

　　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.

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.

With the needs of daily life, extruders are widely used, and can be divided into four areas: drainage area, feeding area, screw conveying area and discharging area.1. The equipment adopts a shaftless screw, and the contact area with the material is small, that is, the friction force is small, which can effectively improve the extrusion efficiency of the extruder, and can avoid problems such as clogging and winding.2. The equipment is made of stainless steel, which has high strength and strong corrosion resistance, so it has a long service life.3.

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.

　　The product produced by the puff snack production line is a kind of extruded snack. It uses advanced co extrusion technology to extrude two kinds of products with different texture and taste on a twin-screw host at the same time to produce popular McChicken pieces, sandwiched rice crisps, rice nuts and other puffed sandwich foods in the market. It can also change molds and auxiliary equipment to produce Breakfast cereal Congee, nutritional powder and puffed snack food of various shapes.
