Corn Extruder Machine-manufacture,factory,supplier from China

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.

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.

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.

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 is developed on the basis of single screw extruder. Two screws are placed side by side in the barrel of the twin screw extruder. According to the meshing degree of the two screws can be divided into mutual meshing type and non-meshing type. According to the rotation direction of the two screw shafts, it can be divided into reverse rotation type and co-rotation type.(1) meshing twin screw: Because the meshing gap of the meshing screw is very small, the material has the ability of forced conveying, not easy to produce backflow, leakage phenomenon.

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.

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.

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

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.
