Corn Puffed Extruder Machine-manufacture,factory,supplier from China

Now puffed food has always been very popular, and many companies and businessmen have seen the profits. In fact, puffed food machinery is the same as food machinery, not only to meet the production conditions that the machinery and equipment should have, but also to meet the various conditions required for food processing. Judging from the current development phenomenon, the procurement of extrusion and puffing machinery should be considered from four aspects.1. Scale applicability.

1. Before operating the corn equipment bulking machine, remove the head, movement, lead screw and other parts, clean them up, dry them and then install them.2. Idling for 1 to 2 minutes first when operating, put the raw materials into the feed mouth, not too fast, when the ring groove of the spiral shaft head is filled, stop feeding, friction preheating. Wait until the nose temperature rises and the pressure inside the cabin builds up before feeding.3. Feed should be continuous and uniform, material must be dry, must pay attention to.4.

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.

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.

The puffed foods such as potato chips, french fries, etc. that we usually see are produced by the puffed food extruder. After a series of operation procedures, the delicious food is presented in front of us.

Puffed food appeared in the market in the 1960s. Later, it quickly became popular in various countries because of its unique taste, simple eating and various patterns. It has long occupied the most frequently purchased snack types with chocolate, wafers and other foods.However, the long-term sales advertisements and puffed food have left us with a stereotyped image. Recently, many consumers said that when they saw the product category as "oil-containing puffed food", they were very worried about whether it was an unhealthy snack.

Screw extruder is mainly used in the production of starch extruded food, protein extruded food and extruded feed in the food industry, and can also be used as a special chemical or biochemical reactor.Starch puffed foodThe starch in the grain will gelatinize (αize) under the high temperature and pressure of the extruder. The results showed that the degree of starch αization was more than 98% and the crude fat decreased by 60% or even disappeared after the puffed corn flour. Water solubility increased by more than 40%. Therefore, extruder can replace roller dryer to produce gelatinized starch.

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.

Food puffing machinery production line mainly uses potato starch, corn starch, flour as raw materials, using a unique extrusion molding process, the production of the popular market of various shapes of the secondary puffed food. Mechanical production line design is reasonable, high degree of automation, accurate extrusion parameter control. The main machine is equipped with high and low pressure screw, which increases the scope of use of raw materials, reduces cost and improves product quality.

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.
