Buying guide ~ help you buy the suitable product

1. Process flow of soy protein extruder:

1) Powder mixing machine (powder mixing) → 2) Screw conveyor → 3) Twin screw extruder (extrusion, cutting and forming) → 4) Air conveyor (conveying) → 5) Oven (baking) → 6 ) Cooling conveyor

The defatted soy flour that meets the specifications is mixed with 25%-30% water into the twin-screw extruder. In this machine, moisture is compressed in a spiral shape under high temperature and high pressure, and the atmospheric pressure is rapidly compressed to produce dry soybean products. Soybean tissue is completely destroyed in the process of pressure reduction, and the digestibility is improved. Harmful physiological substances such as trypsin in soybeans are inactivated by heat, and the inherent beany smell and odor of soybeans are removed, and the product can be made into fiber. Specially structured products such as crystalline, porous structure, sponge, etc., are packaged after cooling and drying.


Decomposition and detailed explanation:

1) Mixing powder machine:

Add different raw materials and auxiliary materials to the powder mixer in proportion to mix various materials. After turning on the machine to mix all the materials, add water and mix evenly.

2) Host:

a) Automatic feeder: After the main machine is warmed up to the temperature, the barrel temperature is stable, and the oil is circulating, the main motor is adjusted to about 700 rpm, and the feeder is started to feed. The feed speed is observed by the DC meter of the control cabinet. At the same time as the initial feeding, evenly add 500ml of water from the feeding port to facilitate the discharging. The feeding speed is from slow to fast. The feeding amount should be in line with the main body's feeding amount. There is no accumulation or empty material. After feeding, pay attention to the instructions of the main motor ammeter at any time, generally 30-40A.

b) Extrusion extruder: In the process of extruding and extruding, the material is placed in a sealed barrel equipped with a screw (spindle). When the screw makes a compound movement with the rotation of the screw, it is affected by mechanical friction and the material inside. The material temperature gradually rises and reaches a high temperature due to the shearing force and the heat energy from the outside of the barrel; because the material is in a sealed state, high pressure is generated as the sealing volume changes and the temperature rises. Therefore, the material is Under the dual action of high temperature and high pressure. It gradually becomes the gel state of superheated rheology and obtains a large amount of energy, which changes the original physical and chemical properties. The larger the screw diameter ratio, the better the maturation effect relative to the soybean protein. The soybean protein processing equipment of Shandong Loyal Industrial Co., Ltd. can generally reach a screw diameter ratio of 36D. The particular screw meshing result is greatly improved. The effect of soy protein extrusion. When the material is extruded into the average temperature and pressure state through the die, a large amount of energy is released instantly, and the volume expands rapidly. The end of the extruder is equipped with a mold, which can be replaced to make the product into different shapes.

c) Rotary cutting device: After the material is extruded, open the rotary cutting device and adjust the rotary cutting speed to cut the product into the required shape and length.

3) Wind conveyor

The formed products are cooled by the conveyor belt and sent to the oven by the wind.

4) Oven

Drying time and temperature can be adjusted. Shandong Loyal Industrial Co., Ltd. oven adopts a hot air circulation system to effectively utilize thermal efficiency and avoid excessive temperature, which may cause gelatinization of materials.

5. Production technology principle:

The technical key and critical point of this production line is the use of extrusion technology. After the material is expanded, the volume becomes more extensive, the taste is crispy, the starch is gelatinized, and the water-soluble components are increased. It is easy to be absorbed by the human body.


The main component of cereals is starch. Since raw starch is insoluble in water and not easily decomposed under the action of enzymes, it is difficult to be digested and absorbed by the human body. Only by swelling it with hot water to make the starch gelatinize can it be digested and absorbed by the human body. However, commonly cooked foods will gradually harden at room temperature or low temperature, and their taste will deteriorate. This is commonly referred to as starch "regeneration", and the starch in this state is called beta starch. The extrusion technology is to make the raw starch of the material gelatinize and become an alpha starch structure that is easily absorbed by the human body. It can maintain a stable alpha structure for a certain time to prevent "regeneration" and maintain a good taste.


The structure of starch is alphabetized, which facilitates the decomposition of various enzymes and degrades nutrients such as starch and protein to varying degrees, increasing water-soluble components. And improve the taste of the product. Due to the high temperature and high pressure, cereal starch is matured very thoroughly, and the starch chain is significantly damaged, so the starch can maintain a stable α structure, which can prevent "regeneration", which is conducive to the long-term storage of the product. During the puffing process, part of the protein is also degraded and decomposed into amino acids that are easily absorbed by the human body. The amino acid content has increased by 70%. In addition, the irreversible thermal denaturation of the protein during the puffing process improves its digestion and absorption rate. Since the expansion of the material is completed in a very short time, the loss of nutrients in the material is much smaller than that of ordinary cooking methods, and the nutrients in the material are retained to a great extent.


In summary, using a twin-screw extruder production line to produce soybean tissue protein has the advantage of providing a variety of nutrients to the human body, solving the problem of single nutrition in the original technology, reasonable design, advanced technology, and high degree of automation. , Soy protein products have good functionality and a wide range of applications.

It can be provided to local supermarkets and school canteens, which is a good project for making profits and getting rich.


7. The nutritional value of soy protein:

The food that the modern population needs should not only cause appetite but also have any adverse side effects and be rich in nutrients. Among the existing food groups, no other crop meets the conditions as mentioned above and has abundant sources of raw materials than soybeans. Foods made with soy protein are hailed as "green foods" by nutritionists. Soy protein has a significant lowering effect on people with high cholesterol. The arginine content in soy protein foods is higher than that of ordinary amino acid-containing foods, such as milk. The arginine ratio to lysine is also reasonable; the lipid and linoleic acid are extremely rich and contain no cholesterol, preventing cardiovascular disease in adulthood. Rich in lecithin, it can remove excess sterols from the blood and is known as the "vascular scavenger." Soy protein foods are easier to digest and absorb. This soy protein is an essential nutrient for everyone. Still, the daily dietary intake is insufficient mainly, and it must be supplemented by eating soy protein products, especially for certain special groups such as children, pregnant women, lactating mothers, and the elderly.


Moreover, the food is rich in seasoning and can have the shape and taste of meat. Compared with meat products, the nutrient content of soy protein is similar, but the calories are meager. It can satisfy the taste needs while taking into account the taste. It is indeed the gospel for most people who lose weight and the "three highs" patients.


8. Maintenance instructions:

1). Check the parts regularly, once a month, check whether the worm gear, worm, bolts on the lubricating block, bearings, and other movable parts are flexible and worn. If any defects are found, they should be repaired in time and should not be used reluctantly.

2). The machine should be used in a dry and clean room and should not be used in places where the atmosphere contains acids and other gases that are corrosive to the body.

3). After the machine is used or stopped, the rotating drum should be taken out to clean and brush the remaining powder in the bucket, and then install it, ready for the subsequent use.
