How to choose soybean oil production process?

Generally, Henan Doing Company will recommend suitable soybean oil production process depend on the requirement of customer, mainly depending on the requirement of final products.

1. In order to extract soybean oil, and get soybean meal which can be used as fodder

The soybean oil production process is as following:
soybean --cleaning --crushing --softening --flaking --puffing/drying --solvent extraction --crude soybean oil/wet soybean meal

Crude soybean oil is sent to oil refinery plant, through a series of processing, to get refined soybean oil.

Wet meal is sent into DTDC system in solvent extraction plant, and finally get dry soybean meal which can be as fodder.

2. In order to get low denatured soybean meal at the same time extracting soybean oil

There is difference from the above soybean oil production process to adopt low temperature desolventizing method in solvent extraction process.

In addition, after flaking, flaky soybean is sent to solvent extrator directly, without puffing or drying, in ordor to reduce the heat treatment.

3. Produce active defatted soybean powder and soybean oil using cold pressing process

Because the oil residual rate of cold pressing process should be control at less than 7%, it is necessary to cold press twice.

The cold pressing process is as following:
soybean --cleaning --crushing --softening --flaking --cold pressing --crude soybean oil/cold pressing soybean meal

Crude soybean oil need filtering by filter machine, and then sent to soybean oil refinery plant.

Cold pressing soybean meal will be superfinely comminuted to get active defatted soybean powder.

How do you manufacture soybean oil?

The methods to manufacture soybean oil are pressing and solvent extraction. Different production volumes and customer needs require different production lines and manufacturing machines. If you want to start a soybean oil production business, how to choose soybean oil manufacturing machines? Next, Henan Glory will give you a detailed introduction to the method to manufacture soybean oil by pressing and solvent extraction method.

For the method to manufacture soybean oil, whether it is the pressing method or solvent extraction method, the oil must be pretreated. The machines used to clean impurities mainly includes vibrating screen, destoner and magnetic separator. The raw materials that have not been cleaned contain impurities such as silt, metal, and pebbles, which will affect the subsequent processes. On the one hand, hard metals and stones will affect the normal operation of the machine, and even cause machine failure in serious cases; on the other hand, silt impurities will absorb part of the oil and reduce the oil yield. And because the particle size of soybeans is large, a crusher is needed to reduce the particle size of soybeans. The purpose of this is to increase the surface area, making it easier to extract the soybean oil. Because the oil content of soybeans is low, a softening pot is needed to soften them and increase the moisture content. After that, an flaking roll is used to press the embryos, turning the oil into thin flakes and shortening the oil path.

The price of soybean pressing production line is relatively low, the oil yield is low, and the residual oil rate is 6%-7%. In addition to vibrating screen, destoner, magnetic separator, crusher, softening pot, and flaking roll, a cooker is also needed to manufacture soybean oil. The function of the cooker is to adjust the temperature and moisture of soybeans. After that, it enters the oil press for direct pressing. After pressing, soybean crude oil and cake are obtained. The crude oil will contain fine impurities, so a filter will be used to remove impurities in the crude oil. Finally, we will get a relatively clean soybean crude oil.

The price of soybean extraction production line is relatively high, the oil yield is high, and the residual oil rate is less than 1%. After pretreatment, The method refers to the use of the miscibility of organic solvents (n-hexane) and oils to extract soybean oil based on the different boiling points of organic solvents and soybean oil. Before extraction, the structure of the oil can be changed with puffing machine, the structural gap can be increased, and the yield can be increased, and then soybean extraction can be carried out. The main machines used in this part include extractor, stripping tower, evaporator, oil-water separator, condenser, stripping tower, etc. Soybean extraction oil contains impurities and substances harmful to the human body. It needs to be refined to remove impurities and harmful substances. Henan Glory Company can provide intermittent, semi-continuous and fully continuous soybean oil refining machine. Besides, we can also match the appropriate soybean oil refining machine for the customer according to the processing capacity of the soybean oil manufacture plant. Moreover, only refined soybean oils can meet the national stability standards and can be sold on the market.

Henan Glory is engaged in the design and manufacturing of soybean oil machines, selling directly at factory prices. It can provide soybean oil manufacturing machines with different processing capacities and can customize machines of different models and processing capacities for customers. If you want to learn more about our machines or the method to manufacture soybean oil, please feel free to contact us, and we will be happy to serve you!

How to make soybean oil from soybean seeds? How many types of extraction method can be used in soybean oil processing process?

In general, there are two methods for extracting soybean oil: one is mechanical extraction method, also called traditional soybean oil extraction method; the other is solvent extraction method, also known as chemical extraction method. Both mechanical extraction method and solvent extraction method all can achieve the goal of effective extraction of soybean oil.

The difference between mechanical way of soybean oil extraction and chemical way of soybean oil extraction is that: the mechanical extraction method is simple in operation, small in area, but the residual oil rate is high, and the residual oil rate is about 7% to 8%. Soybean oil solvent extraction methods are relatively complex, but the residual oil rate is low , the residual oil rate is less than 1%. You can choose one depending on your capacity and your fuel needs, or you can use two together.

Mechanical extraction method:
The mechanical extraction method refers to a machine that extrudes soybean oil from soybean by increasing the temperature and activating the oil molecules by means of the action of mechanical external force. The mechanical extraction method is suitable for family workshop or small soybean oil mill (1-30 tons). The most commonly used soybean oil press machine are: single screw soybean oil press machine, intergrated soybean oil press machine with filter.

Solvent extraction method:
Soybean oil solvent extraction, also known as "extraction", is a process in which oil is extracted from an oil with an organic solvent. Soybean oil solvent extraction method is suitable for large edible oil processing plants (over 30 tons). Soybean oil solvent extraction plant is as follows:
