puffing food machine-manufacture,factory,supplier from China

What are the characteristics of single-screw extruder, twin-screw extruder and different extruders?There are more and more puffed foods on the market, and various puffed feeds are introduced. The characteristics of several puffing machines are introduced.

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

Explain the daily operation and precautions of the extruder.(1) Precautions before starting:1. Check all parts, especially the connecting screws and anchor bolts of each section of the puffing chamber, the connecting bolts between the motor base and the frame, and the bolts between the puffing chamber and the frame, and there must be no looseness.2. Rotate the main shaft by hand, and there should be no rubbing sound in the puffing cavity at this time.3. Start the feeding auger, check its stepless speed regulation performance, and require normal operation.4.

When purchasing a large airflow puffing machine, the following points are what companies need to pay attention to:1. It is necessary to check whether the manufacturer has production conditions, production equipment, design and manufacturing capabilities, test reports from the relevant departments of the country that can provide equipment, and producer's qualification documents.2.

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.

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.

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.

The puffed food machine is composed of three screws in the puffing chamber. The three screws shear each other, which is equivalent to three sets of twin screws running simultaneously in one puffing chamber. There are three nip points, so the shearing efficiency is high and the material is easy to plasticize. The resulting pressure is greater, the degree of maturation is better, and the amount of nutrients such as protein and fresh meat is added.

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.

Food puffing machinery production line mainly uses potato starch, corn starch, flour as raw materials, using a unique extrusion molding process, the production of the popular market of various shapes of the secondary puffed food. Mechanical production line design is reasonable, high degree of automation, accurate extrusion parameter control. The main machine is equipped with high and low pressure screw, which increases the scope of use of raw materials, reduces cost and improves product quality.
