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

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.

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.

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.

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 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 twin-screw extruder has the advantages of strong adaptability, sliding conveying and self-cleaning, but its structure is complex, the cost is high, and the corresponding maintenance and operation costs are also high. Therefore, twin-screw extruders are generally used in the production of high value-added aquatic and pet feeds, such as the production of eel, soft-shelled turtle and juvenile fish feed, because the prices of these products in the market are sufficient to return the manufactured products of twin-screw technology.

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

Food freeze-drying machine is short for food vacuum freeze-drying machine. Food freeze-drying technology originated in the 1930s. At present, food freeze-drying machine has become an important drying equipment for food deep processing.Freeze-dried food is fast frozen, vacuum ice dehydration, preserving the original color, aroma, taste, nutrition and appearance of the original material, and has good rehydration, and does not contain any additives, can be stored at room temperature for a long time, is an ideal natural health food.

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.
