french fry extruder-manufacture,factory,supplier from China

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.

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.

Since the beginning of this year, affected by the supply chain, many foreign fast food chains have fallen into a shortage of fried chicken and french fries. On the other hand, the lack of market supply reflects the large demand for frozen fries and other ingredients in the market. As a major producer of potatoes, in the process of developing the potato industry, we should promote the transformation of potato processing products from single to diversified according to market demand and local conditions.

The puffed foods such as potato chips, french fries, etc. that we usually see are produced by the puffed food extruder. After a series of operation procedures, the delicious food is presented in front of us.

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.

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.

Extrusion technology, as an economical and efficient processing method, has been widely used in food and feed industry in recent years. The twin screw extruder has incomparable advantages over the single screw extruder. Its advantages such as wide processing range, high curing, strong self-cleaning ability and stable operation control are gradually recognized by everyone. For the food industry with high requirements, these advantages of twin screw extruder can be better played.

The fiber-drawing protein of twin-screw extruder takes low-temperature soybean meal, soybean protein isolate and wheat gluten as main raw materials. In the twin-screw extruder, the processes of extrusion, forced transportation, crushing and kneading, mixing and homogenizing, shearing and extrusion are completed. At the same time, the processing process of high temperature and high pressure and sterilization is continued to modify protein molecules and form a new layered fiber structure. Produce high-strength, high-toughness, texture and taste similar to meat.
