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.

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.

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.

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.

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.

Directly puffed food is generally required to be dried after extrusion processing. The moisture content of the dough in the extruder is 15%~20%. The product is then dried to reduce the moisture content to 2% to 3% to create the environment needed for a crunchy texture and stable shelf life. Due to the low density of the product, the drying time is usually very short, so it should be carried out in a warm warehouse.Coatings to produce direct-expanded products Extruded and dried products are finally sprayed with oils and seasonings.

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 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
