Soya Food Extruder-manufacture,factory,supplier from China

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.

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.

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.

When using a twin-screw extruder, the twin-screw extruder needs to install the device correctly, so that it can save energy and time during production.The twin-screw extruder is fully automated from batching, extrusion, puffing, molding, core sandwiching, cutting, spraying to finished products at one time. The production line has the characteristics of many optional models, flexible equipment configuration, wide range of raw materials, many types of products, and simple operation.

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.

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 textured soya protein production line takes low-temperature soybean meal, peanut meal, etc. as the main raw materials, and can produce Histone, artificial meat and other foods with certain strength and toughness. The product shapes include columns, squares, thin slices, thin strips, granules, etc., and can be widely used in canned goods, seasoning, ham, and meat products.　　Technological process of textured soya protein production line:　　1. Mixer: Mix the raw materials required for production with a certain amount of water thoroughly and evenly.　　2.

When operating a twin-screw extruder, it should be maintained on time. The maintenance process is carried out after the twin-screw extruder runs continuously for 2500-5000h and shuts down. The screw is extracted to inspect, measure and identify the wear condition of the most critical components, replace the components that have reached the specified wear limit as soon as possible, and repair the damaged components . The maintenance standard of the reducer of the twin-screw extruder is the same as that of the ordinary standard reducer.
