High temperature roller oven-manufacture,factory,supplier from China

What is a roller assembly line? As the name implies, it is to use roller conveyors as the transmission machinery of the whole assembly line, which can transport some flat-bottomed items along a horizontal angle or a smaller inclination angle. For parts such as boards, non-flat-bottomed items or flexible items can be transported by pallets or other flat-bottomed containers.Why use a roller conveyor as the transmission machinery of the assembly line? The reasons are as follows:1.

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.

The fiber-drawing protein of twin-screw extruder takes low-temperature soybean meal, soybean protein isolate and wheat gluten as main raw materials. In the twin-screw extruder, the processes of extrusion, forced transportation, crushing and kneading, mixing and homogenizing, shearing and extrusion are completed. At the same time, the processing process of high temperature and high pressure and sterilization is continued to modify protein molecules and form a new layered fiber structure. Produce high-strength, high-toughness, texture and taste similar to meat.

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.

1. Product formationHigh-density drawing protein adopts a variety of all-natural vegetable proteins at home and abroad through high pressure and high temperature and special processing of soybean drawing protein, so that the vegetable protein undergoes physical reaction in an instant, so that the protein is highly agglomerated and organized, and it is automatically sorted according to the characteristics of each protein. Form a high-density filamentous structure, and finally make vegetarian meat products of various flavors.2.

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.

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.

The pet chew production line is specially used for the production of dog chew products. It uses a unique extrusion method and mold to produce strip, rod, twist, two-color or multi-color chews with various shapes and sandwiches.1.

The twin-screw extruder has the advantages of strong adaptability, sliding conveying and self-cleaning, but its structure is complex, the cost is high, and the corresponding maintenance and operation costs are also high. Therefore, twin-screw extruders are generally used in the production of high value-added aquatic and pet feeds, such as the production of eel, soft-shelled turtle and juvenile fish feed, because the prices of these products in the market are sufficient to return the manufactured products of twin-screw technology.

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
