4. The structure of the food extruder machine

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 of stress, the water vapor expands and dissipates rapidly, making the product form a porous structure, and the expanded material is The rotating knife cuts into a specific size product. In the production of breakfast cereals, single-screw extruders and twin-screw extruders are most commonly used, and twin-screw extruders are more advantageous than single-screw extruders because single-screw extruders are Material particle size, moisture requirements, and composition requirements are strict. It is easy to cause problems such as material backflow and effortless wear of the screw.

The puffing process of the product is mainly completed by baking or frying after extrusion. In this process, after the raw material is passed through the extruder, the raw material is only matured, and semi-cooked and the product are given a specific shape. At the same time, to improve the quality of the product, make the texture of the product more uniform, and the gelatinization more thorough, the extruded semi-finished product needs to go through a constant temperature and humidity process and then undergo post-baking or frying processes. The extruder adopts extrusion technology to process various puffed foods and fortified foods and is suitable for processing in many food production fields such as snack foods, instant grain foods, convenience foods, dairy products, etc., and the product can be changed by simply changing the mold Shape, produce products of different shapes and patterns, so the product range is wide, the variety, the color is uniform, and it can form a series of products, which is conducive to the flexibility of production and sales.


5. How does the twin-screw food extruder machine work?

Different extruders produce different products. Different combinations can produce other effects.

The twin-screw extruder is composed of two mutually meshing and co-rotating screws installed on the barrel's spline shaft. As there are various screw and barrel designs, various screw shapes and process functions can be set according to process requirements. Therefore, the twin-screw extruder technology can ensure a high degree of flexibility in transportation, compression, mixing, cooking, shearing, heating, cooling, pumping, and shaping. The main advantage of the intermeshing co-rotating twin-screw extruder is its remarkable mixing ability, which gives the extruded product unique characteristics.

It can also be used as a food binder, a tackifier, a binder for casting sand, a tackifier for the weaving and dyeing industry, and a raw material for floating bait.


8. The development history of food extruder machine

The extruder originated in the 18th century. The manual piston extruder used to manufacture seamless lead pipes manufactured by Joseph Bramah (England) in 1795 is considered the world's first extruder. Since then, during the first 50 years of the 19th century, the extruder was only suitable for producing lead pipes, the processing of macaroni and other foods, brick making, and ceramic industries. In the process of development as a manufacturing method, the first time it was documented was R. Brooman's patent application in 1845 to produce Goodbo glue wires with an extruder. H Bewlgy then improved the extruder and used it to coat the copper wire of the first submarine cable between Dover and Calais in 1851. In 1879, British M. Gray obtained the first patent for the use of Archimedes spiral screw extruder. In the following 25 years, the extrusion method became critical, and an electrically operated extruder quickly replaced the manual extruder. In 1935, the German machinery manufacturer Paul Troester produced an extruder for thermoplastics. In 1939, they developed the plastic extruder to a current stage-the modern single-screw extruder stage.


9. Cleaning method of food extruder machine

In food production, the same equipment needs to produce different foods, which leads to the mixing of flavors and raw materials between other foods, which seriously affects the taste of food. The food production machinery is thoroughly cleaned to ensure. The taste of food is pure.

The cleaning of food machinery is divided into routine cleaning and regular cleaning according to the cleaning frequency. Routine cleaning refers to cleaning after each mechanical use. Although this cleaning is timely but not thorough, it is easy to cause the deposition of contaminants. Regular cleaning is a thorough cleaning of the equipment at a designated period. By using various cleaning fluids for different purposes, increasing the concentration, temperature, and impact force of the cleaning liquid, the various residues and microorganisms generated in the equipment can be thoroughly removed. According to specific cleaning methods, it can be divided into the following cleaning methods: manual cleaning, foam cleaning, high-pressure cleaning, positioning outside cleaning, and positioning cleaning.


10. How to maintain the food extruder machine?

For frequent use, the reducer must be replaced with new oil every three months. When returning, the reducer should be cleaned and added with fresh oil. The machine parts are inspected regularly 1-2 times a month. The inspection parts are worm gears, worms, bearings, and oil seals. Whether the running parts are flexible and whether the fasteners are loose. Any abnormal situation should be dealt with in time. During use, if the machine is found to vibrate abnormally or make an abnormal sound, it should be shut down immediately for an inspection. Electrical control parts should be kept clean and sensitive, and faults should be repaired in time. When assembling and disassembling the stirring paddle, it should be dismantled gently, steadily installed, and placed with care to avoid deformation and damage. After use, the residual materials in each part of the machine should be brushed. The device should be used for a long time. The appliance must be wiped and cleaned. The surface of the machine parts should be coated with anti-rust oil and covered with tarpaulin.

2. Extrusion operation parameters: type of extruder, feeding speed, screw geometry, extruder length, screw speed, die characteristics, the temperature of the cavity.


14. The development status and development trend of food extrusion processing technology

Foreign :

In recent years, developed countries have been steamed and extruded food as a single large category of food, and penetrate many food processing, such as puffed rice can be further produced staple bread, cooked products, fried products, etc.; corn extrusion puffed and crushed, added to the bread, so that bread has a unique taste and flavor.

Food steaming extrusion processing technology has become the object of research and development of many researchers and production plants in developed countries. Japan has published many patents on extruded puffed products, such as extruded cheese products, extruded starch products, and the use of tofu residues to produce extruded food, and other patents. 1980, U.S. scholars have studied the flavor and color of extruded fast food. In the 80s, the United States, Japan, and other countries to extrusion of defatted soybean tissue, the production of a variety of bionic foods (such as meatloaf, salted beef, ham, etc.) and milk drinks In the 1980s, the United States, Japan, and other countries extruded and organized soybeans to produce a variety of bionic foods (such as meatloaf, salted beef, ham, etc.) and milk replacer drinks, instant drinks, etc. Sweden, the United States, and other countries use inexpensive bran as raw materials, after extrusion and puffing, the production of high-fiber health food.


China's research and understanding of extruded food began as early as the mid-1970s, but due to scientific research units invest in this force is not enough; the relevant departments do not pay enough attention; manufacturers to meet a half-understanding, so that our consumers on the extruded food awareness of a common misconception: extruded food and popcorn is a class of products, to coax children to play with a kind of children's food. Equipment manufacturers in the digestion and absorption of foreign equipment gaps exist so that the performance of equipment is far below the imported equipment, affecting the progress of product development. At present, the research on cooking extrusion processing technology in China is still relatively backward. Few researchers specialize in this technology research. Theoretical research lags and product development can not keep up. The performance of equipment is not perfect manufacturers vary in technology. But we never stop at the front. In the food, extrusion machine technology has made great efforts.
