french fry extruder-manufacture,factory,supplier from China

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.

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.

When operating a twin-screw extruder, it should be maintained on time. The maintenance process is carried out after the twin-screw extruder runs continuously for 2500-5000h and shuts down. The screw is extracted to inspect, measure and identify the wear condition of the most critical components, replace the components that have reached the specified wear limit as soon as possible, and repair the damaged components . The maintenance standard of the reducer of the twin-screw extruder is the same as that of the ordinary standard reducer.

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 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.

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 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.

The control of the operating parameters of the extruder includes: control of the temperature and humidity of the raw material entering the extruder; control of the temperature and pressure of each section of the extruder; control of the maximum point of dough viscosity in the extruder; extrusion speed control of extrudate temperature and time in each section; time control when the product temperature rises to the maximum extrusion temperature and temperature control at the final outlet.In principle, the longer the dough stays in the extruder, the more energy it can absorb and the temperature w

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.
