Extruder Fish Food Machine-manufacture,factory,supplier from China

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.

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.

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.

THE MAIN ASPECTS OF HARM CAUSED BY FOOD CONTAMINATION1. Biological pollutionIt is mainly caused by harmful microorganisms and their toxins, parasites and their eggs and insects. Animal foods such as meat, fish, eggs and milk are easily contaminated by pathogenic bacteria and their toxins, leading to bacterial food poisoning and zoonotic infectious diseases. Pathogenic bacteria mainly come from patients, carriers and sick animals, sick birds and so on.2. Radioactive contaminationThe harm to human health has many manifestations.

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.

In the past, "I know the taste of the sea" once made bagged instant seaweed snacks deeply rooted in the hearts of the people, basically opening a new era of cross-generational development of seafood snacks. With the accelerated development of my country's "deep blue economy" in recent years, the use of new food processing technologies and new processes to vigorously develop marine leisure food in the true sense has become an important direction for the development of the marine product industry. Grilled fish fillets, cod sausages, etc.

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

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.

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.
