Fish feed making 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.

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.

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 new-style tea market, which is considered to be a high-quality track, seems to be a bit "glamorous in appearance, but full of challenges in reality". Recently, Nai Xue's tea released its first annual report after its listing. The adjusted net profit loss of 145 million yuan is somewhat surprising, but industry insiders also said that with the brand's pilot and a series of automated tea-making equipment this year, the store's operating results will be improved. Release it slowly.

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.

Main parts and componentsScrew: is the main component of the bulking machine, indicating the parameters of the screw structure are diameter, pitch, root diameter, spiral Angle and blade section structure. The length to diameter ratio of extruded parts and the gap between the screw and the inner wall of the expanding cavity also have great influence on the performance of the expanding machine.Discharge die: It is the last checkpoint of the product through the expanding machine.

The processing of pet feed mainly refers to the use of different means and methods to process and shape raw materials. Pet nutrition can be formed, palatability and digestion and absorption are greatly improved. Play nutritional value and use value.Puffing is a food processing method. Raw materials are added to the puffing cavity, and after heating and pressurizing, the pressure is suddenly reduced. The moisture in the food expands and vaporizes, and many pores appear, making it crispy and delicious.

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.

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.

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.
