extruder equipment-manufacture,factory,supplier from China

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.

Twin screw extruder to keep clean can produce better products, keep clean can also reduce the occurrence of failure rate, ensure the continuous production, twin screw extrusion equipment maintenance basic elements - inspection, cleaning.The inner wall of cooling water pipe attached to twin screw extrusion equipment is easy to scale, and the outside is easy to rust and corrosion. The maintenance should be carefully checked.

With the needs of daily life, extruders are widely used, and can be divided into four areas: drainage area, feeding area, screw conveying area and discharging area.1. The equipment adopts a shaftless screw, and the contact area with the material is small, that is, the friction force is small, which can effectively improve the extrusion efficiency of the extruder, and can avoid problems such as clogging and winding.2. The equipment is made of stainless steel, which has high strength and strong corrosion resistance, so it has a long service life.3.

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 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 dryer adopts the principle of multi-layer utilization of hot air, which is suitable for dehydration and drying of various herbs, dried fruits, vegetables and other flake, block, strip and granular items. It can also be used for drying and dehydration of dried tofu, marinated eggs and poultry products on the surface of cooking and marinating. The pure hot air generated by the hot air furnace is used, and the hot air temperature is controllable from 50°C to 160°C. Two drying and dehydration methods, heating drying and ventilation drying are used at the same time.

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.

There is only one screw in the barrel of the single screw extruder, it is by the friction of the screw and the barrel of the material to transport materials and form a certain pressure. In general, the friction coefficient between the material and the barrel is greater than that between the material and the screw. Otherwise, the material will be wrapped in the screw together to rotate and not play the role of forward propulsion.Screw is divided into three sections: feeding (feeding) conveying section, compression melting section, metering homogenization section.

The twin-screw extruder uses twin-screws to extrude and expand materials. Combining our rich experience in the research and development of puffed food machinery for many years, we can produce puffed food equipment suitable for my country's national conditions.

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.
