puff extruder machine-manufacture,factory,supplier from China

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 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.

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.

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.

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.

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.

Extrusion technology, as an economical and efficient processing method, has been widely used in food and feed industry in recent years. The twin screw extruder has incomparable advantages over the single screw extruder. Its advantages such as wide processing range, high curing, strong self-cleaning ability and stable operation control are gradually recognized by everyone. For the food industry with high requirements, these advantages of twin screw extruder can be better played.

　　Before you get a food extruder, make sure you do your homework on the machine you’re buying so you can get the most out of it. Consider these things before you buy an extrusion machine.Type Of Extruder:　　Piston extruders, roller-type extruders, and screw extruders are the 3 kinds of extruders commonly used to make packed food products, with the latter being the most common.　　For food processing, you should determine if you require a single-screw extruder or a double-screw extruder.

As a food processing equipment, the food extruder has many precautions in use. For example, we need to remove the machine head, movement and lead screw before starting the operation, and we must carefully clean the rice on the machine. dirt and oil, and then re-installed. Only in this way can the material reach the required state and quality. So in the process of Jinan puffing extrusion equipment operation, what should we pay attention to?Matters needing attention during the operation of the extruder are:1. Mainly use corn and potatoes as raw materials to produce small food.2.

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.
