extrusion frying machine-manufacture,factory,supplier from China

Working principle: The raw materials are cooked in the extruder and pushed through the template when the temperature is lower than 100°C, and the raw material dough is formed at a low temperature, which can prevent the moisture in the material from instantly turning into steam and causing puffing. The puffing process of the product is mainly completed by baking or frying after extrusion. In this process, after the raw materials pass through the extruder, the raw materials are only matured and semi-cured, and the product is given a certain shape.

At present, European and American countries have become leaders in the research on cereal breakfast food. Countries have carried out research based on local eating habits and tastes of groups to form a system of cereal breakfast food products tailored to local conditions. The extrusion technology in my country is mainly concentrated in the field of puffed food and tissue protein, and the research on the production of cereal breakfast food by extrusion technology is relatively weak, and it can be said that it is still in its infancy.

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.

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.

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.

Materials with a certain moisture content and starch content are pushed by the screw in the sleeve of the extruder and reversely blocked by the discharge die (or throttling device in the sleeve), as well as by external pressure. Heating, or the heating effect of the frictional heat between the material and the screw, the material and the material, and the material and the inside of the sleeve, makes the material in a state of high pressure as high as 3-8MPa and a high temperature of about 200°C.

Puffed food refers to the food in which the volume of raw materials such as grain or protein is expanded many times after being processed by puffing extrusion machinery, and the internal organization becomes a porous and loose sponge-like structure.In a broad sense, puffed food refers to any food that uses technologies such as frying, extrusion, sand frying, roasting, and microwave as the curing process, and the volume increases significantly before and after the curing process.There are two methods for food puffing: one is to use rapid heat to rapidly vaporize the water; the other is to sudde

After pre -processing the materials are crushed, wet, mixed, and preheated, the driving force of the squeezing screw is used to form a specially designed mold hole to form a certain shape and organizational state, which is called extrusion processing.The basic principle of squeezing and puffed is: grain raw materials containing a certain amount of water, sealed in the patch machine, for heating, pressurizing or mechanical effects, so that the material is in a high temperature and high pressure state.

At the end of the extrusion cavity, the molten material is extruded through the die hole of the template under the action of high pressure. Due to the sudden drop in pressure, the water vapor expands and dissipates rapidly, making the product form a porous structure, and then the expanded material is extruded The rotary knife cuts the product to a certain size.

In the past, our country has been mainly in the low-end, however, with the constant innovation of technology, the extrusion machine in our country has formed the advantage of high cost performance ratio, not only preempted the market opportunity, but also had a certain position in the international market.After the long-term development, the international influence of Chinese plastic machine industry is constantly increasing, coping with the ability of trade protectionism, the level of manufacturing technology and the overall strength further improve, therefore, our extrusion industry in forei
