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.

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.

At the end of the extrusion cavity, the molten material is extruded through the die hole of the template under the action of high pressure. Due to the sudden drop in pressure, the water vapor expands and dissipates rapidly, making the product form a porous structure, and then the expanded material is extruded The rotary knife cuts the product to a certain size.

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.

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 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.

Protein meat, also known as protein meat or artificial meat, is actually a protein product that mimics the color and taste of meat. It is made of high quality peanut protein powder or soybean and wheat protein by heating, extrusion, puffing and other processes. According to the determination of its protein content for eggs, fish, pig, cattle lean protein 2-3 times, by the health department identification, non-toxic and harmless, is a kind of green, safe, health food.PRODUCT CHARACTERISTICS1. White color, fragrance and low fat.

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.
