Snack Food Extruder-manufacture,factory,supplier from China

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.

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.

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.

Puffed snack food is a kind of brittle food with delicate taste and rich taste. With the improvement of Chinese living standard and the change of consumption concept, all kinds of grain puffed food as a convenient, quick, nutritious leisure small snack, quickly enter many households. Leisure food production line has many optional models, flexible equipment configuration, a wide range of raw materials, a wide range of product types, simple operation and so on.

Indirect puffed snack foods are also known as "third generation snack foods". The production of these foods has a common characteristic: they are not puffed directly after coming out of the extruder template. Additional processing steps are required to give it the appearance or texture, which generally includes frying or hot air puffing processes to remove moisture to obtain the final texture.

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.

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.

　　The puff snack extruder has two pairs of screws that mesh with each other and rotate in the same direction. They jointly play the roles of conveying, friction extrusion and heating. The materials are input by the principle of positive displacement for forced conveying, and pressure backflow is rarely formed.　　Thus, the problem in this respect on the single screw extrusion extruder is better solved, and strong conveying. puff snake extruder integrates compression, mixing, mixing, shearing, melting, sterilization, expansion, molding and other functions, and is completed in a very short time.

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.
