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

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.

Extruder belongs to a kind of equipment for processing puffed food. It is a kind of equipment for processing puffed food, such as processing rice, corn, soybean, wheat, etc., in daily life.

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.

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.

Working Principle of Twin Screw ExtrusionAfter a certain amount of pulverization, the material with a certain water content is fed into the extruder cavity, so that the material will undergo mixing, shearing, A series of complex continuous processes such as melting, curing and sterilization. Because there is a certain air pressure difference inside and outside the barrel, the moment the material is extruded, the external pressure it is subjected to is reduced to normal pressure, so that the material is instantly puffed.

Corn chip is a kind of brittle food, with good rehydration, external flushing not rotten, smooth taste, grain flavor rich.

When the puffed and extruded food machine is operating, we must first think about a problem, that is, how to use the food extruder correctly in the process of using the machine, so I will explain the suitable processing method for novices.1. When it is found that the spiral groove is blocked, do not stop the machine immediately, it should run for a while after stopping the feeding, and then stop the machine when there is a burning smell. In this way, the nozzle and the screw sleeve can be prevented from being seized.

Extruder is the key of extruding technology. Extrusion processing technology as an economical and practical new processing method is widely used in food production, and has been rapidly developed. Extrusion processing mainly by an extruder step to complete the raw material mixing, curing, crushing, sterilization, pre-drying, molding and other processes, to make puffed, organized products or not puffed products.

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.
