extruder dog food-manufacture,factory,supplier from China

The processing of dog food is mainly through a variety of different means and methods, and various raw materials are added to it to make shaped food. This food can meet the nutritional content of pet dogs.

Bulking process is also a process of shaping dog food raw materials. The forming process in the form of steam will add water, so that the dog food raw starch gelatinization, temperature to 100 degrees Celsius -180 degrees Celsius, because the extrusion pressure is very big, extrusion instant pressure release, water out of the particle moment, so that the dog food rapid expansion foaming, water evaporation, so that after the puffed manufacturing process of dog food generally has a good absorption of high nutritional value.1. Puffing equipment to improve the palatability of dog food.

The pet chew production line is specially used for the production of dog chew products. It uses a unique extrusion method and mold to produce strip, rod, twist, two-color or multi-color chews with various shapes and sandwiches.1. Process flow of dog chewsRaw material preparation → mixing → extrusion molding → cooling and conveying → cutting machine → conveying → drying → packaging.2.

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.

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.

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.

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

The difference between single screw extruder and twin screw extruder1. Differences in useThe food generally produced by the twin-screw extruder does not require a large extrusion force. The extrusion force of twin-screw extruder is not as good as that of single-screw extruder, so it is generally used for products such as snacks and dog food that do not require high extrusion.The single-screw extruder generally needs a large extrusion force to make some food.

Explain the daily operation and precautions of the extruder.(1) Precautions before starting:1. Check all parts, especially the connecting screws and anchor bolts of each section of the puffing chamber, the connecting bolts between the motor base and the frame, and the bolts between the puffing chamber and the frame, and there must be no looseness.2. Rotate the main shaft by hand, and there should be no rubbing sound in the puffing cavity at this time.3. Start the feeding auger, check its stepless speed regulation performance, and require normal operation.4.
