Soybean Microwave Degreasing Equipment

Defatted soybeans contain a variety of essential nutrients and have extremely high nutritional value.The calcium content of defatted soy protein is 40 times higher than that of the same amount of beef. The phosphorus content is 3-4 times higher than that of beef and lean pork, and the iron content is 10 times higher than that of milk and beef.

Defatted soy can prevent rickets, tooth dysplasia and anemia, can lower the body’s serum cholesterol, prevent arteriosclerosis, cerebral hemorrhage, heart disease and other diseases.

Soybean microwave degreasing equipment is a new helper for the soybean degreasing process.Compared with traditional degreasing, soybean microwave degreasing technology has significant advantages such as low energy consumption, high automation and low production cost.

Soybean Microwave Degreasing Equipment

Advantages of Soybean Microwave Degreasing Equipment:

1.Soybean microwave degreasing machine has high working efficiency. It takes dozens of hours for traditional technology to degrease soybean, and the whole process of microwave heating degreasing is only about 20 minutes.

2.Soybean microwave degreasing machine has high utilization rate of soybean. The traditional process can only use 40%-60% of soybean, while the utilization rate of microwave dry decarburization is almost 100%.

3.Microwave soy degreasing equipmentconsumes little energy.The traditional process consumes a lot of coal, water, soybean microwave degreasing equipment only uses electricity, which greatly saves energy.

4.Microwave soybean degreasing machineis dual-purpose and cost-saving.Microwave heating has thermal and biological effects, can kill bacteria at lower temperatures, improving product quality and extending product shelf life.

5.Microwave soybean degreasing machineis advanced in technology and easy to control.The equipment does not need to be preheated, there is no thermal inertia, as long as the microwave power is controlled, it can be immediately heated and terminated.

6.Soybean microwave degreasing equipment adopts automatic control.The PLC system supports one-button setting, the system is fully automatic, and the operation is flexible and convenient.Soybean Microwave Degreasing Equipment

Traditional Soybean Degreasing Process:

1.Press method

The pressing method is divided into cold pressing method and hot pressing method.

The cold pressing is a method that directly press the softened soybean to extract the oil and obtain the defatted soybean without heating. Because the protein was not heated before pressing, the protein denaturation was small, and the soluble protein retention rate of defatted soybean could reach 80% ~ 90%.However, the defatted soybean obtained by the cold pressing method has a high fat content (5% to 10%), so it is easy to cause oxidative rancidity of the oil during storage.

The soybean is preheated and flattened, and heated by steam during the pressing process to reduce the viscosity of the oil and make it easy to flow out. For example, soybeans are heated at a temperature of about 125 °C before oil extraction. When oil is pressed, it is kept at a pressure of 137.2 to 166.6 MPa for 1 to 3 minutes, and the heat is above 130 °C, so it is called hot pressing. The defatted soybean obtained by the hot pressing method has low fat content, less water and easy to be pulverized, but the soy protein has a considerable heat denaturation, and the ratio of water-soluble protein (to the whole protein) is below 30%.

Solvent extraction

The solvent leaching method can be divided into two types, batch type and continuous type.Batch solvent leaching, because defatted soybeans and solvent separation are in direct contact with steam, so the degree of protein denaturation is high. The continuous type is to remove the solvent by decompression or indirect heating of the solvent and the like, so that low-denatured nonfat soybeans can be produced.

The solvent leaching method is a method in which soybeans are subjected to appropriate heat treatment (temperature below 100 ° C), crushed, and then extracted with an organic solvent to obtain nonfat soybeans.

In general, the solvent used to make nonfat soybeans is hexane which has a strong hydrophobicity.The method for separating nonfat soybeans from the solvent mainly depends on the nature of the solvent, that is, the degree of hydrophilicity and the boiling point, and the method of solvent leaching. As described above, when the hydrophilicity is small and the low-boiling organic solvent is used, the nonfat soybean can be made at a low temperature, so that the denaturation of the protein is small, and vice versa, the denaturation of the protein is strong.

The traditional soybean powder production process features:

Long production cycle, large equipment investment, low soybean utilization, high energy consumption,high labor intensity and high product cost.But cannot effectively remove the smell of beans.

Microwave technology has been widely used in various types of food industry such as drying (microwave drying equipment), sterilization (microwave sterilization equipment), baking (microwave baking equipment).

Microwave degreasing equipment makes full use of the advantages of microwave super penetration and rapid heating, and it is emerging in soybean degreasing.

In the future, with the continuous development of the food industry, people’s awareness of environmental protection will increase, microwave soybean degreasing equipment and microwave meat degreasing equipment will have more use.
