extrusion frying 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.

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.

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.

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.

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.

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.

Food freeze-drying machine is short for food vacuum freeze-drying machine. Food freeze-drying technology originated in the 1930s. At present, food freeze-drying machine has become an important drying equipment for food deep processing.Freeze-dried food is fast frozen, vacuum ice dehydration, preserving the original color, aroma, taste, nutrition and appearance of the original material, and has good rehydration, and does not contain any additives, can be stored at room temperature for a long time, is an ideal natural health food.

Achieving Extrusion Press Automation LevelActively explore the application of computers in the design, simulation, and automatic control of extrusion extruders and their production lines, so as to improve the automation level, stability and reliability of the whole machine. Realize automatic start-up, study automatic start-up valves, and simplify the process of opening, The operation steps when shutting down save time, reduce material loss and energy loss.

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

1. The food extruder improves the material processing characteristics.Extrusion has a great influence on the physical and chemical properties of materials. After the material is extruded and expanded, its expansion force increases, its water holding capacity is improved, its solubility is greatly improved, and its specific surface area is increased. The change of physical and chemical properties also greatly improves the processing characteristics of materials.2.
