Soybean Oil press Flow Chart:
Soybean pretreatment->Pressing->Filtering->Crude soybean oil
Soybean Cleaning
The soybean cleaning process is the screening and stone removal process. Cleaning is very important for the oil pre-treatment process. It is necessary to use a cleaning screen to remove large impurities, a magnetic separator to remove metal impurities, and a destoner to remove hard impurities such as mud in the material. Equipped with a suction air net system, it can effectively control the dust of raw materials and ensure the cleanliness of soybean raw materials
Soybean Crushing
After the crusher crushes the soya raw materials, the surface area increases, which facilitates the transfer of temperature and moisture during steaming and frying, and improves the steaming and frying effect.
Soybean Softening & Rolling
The function of conditioning is to adjust the moisture and temperature of the soybeans so that they have a certain degree of plasticity, making it easier to separate the oil from the embryos during pressing. Soybean rolling is the process of using the mechanical function to roll the soybean from the granular to the flake.
Soybean oil pressing
Oil pressing process is a mechanical extraction method by using a screw press to squeeze oil out of pre-treated and clean soybeans under pressure. The daily capacity of the screw press varies from 1 ton to 50 tons, and it is the most commonly used method for continuous mechanical extraction of oil and grease. Usually, the oil yield of the physical press method is 65%-70%, which is suitable for small commercial processing plants and medium-sized screw press oil plants.
Soybean Oil Refining Process
Soybean oil refining equipment is used to process the extracted soybean crude oil. Through the degumming. deacidification, decolorization, and deodorization sections, harmful and useless substances in the crude soybean oil are removed, thereby improving the storage stability of soybean oil and making the color and smell of the oil meet the standards of edible oil.Refining is to remove impurities, odors and pigments from peanut oil and improve the quality and taste of the oil. The refining process mainly includes steps such as degumming, deacidification, decolorization and deodorization.
Degumming mainly removes phospholipids and other colloidal substances from peanut oil. By heating and adding chemical reagents, colloidal substances such as phospholipids are aggregated into larger particles, which are then removed by centrifugation or filtration.
Deacidification is to reduce the free fatty acid content in peanut oil. Alkaline refining or distillation is usually used for deacidification. The alkali refining method is to add an appropriate amount of alkali solution to neutralize the free fatty acids to generate soap stock and glycerol, and then remove the soap stock through centrifugation or filtration.
Decolorization mainly removes pigments from peanut oil to make the color of the oil clearer. Adsorption decolorization method is usually used, that is, adsorbents such as activated carbon are used to absorb pigments and other impurities in oil.
Deodorization to remove odors and volatile substances from peanut oil and improve the taste and stability of the oil. Deodorization usually uses high-temperature vacuum distillation, under high temperature and vacuum conditions, the odor components in peanut oil are volatilized and removed through condensation collection.
During the deacidification and deodorization process, free fatty acids and low molecular weight substances are distilled out under high temperature vacuum and direct steam conditions. The physical refining deodorization temperature is higher than the conventional temperature. Generally around 260 degrees. During the operation, attention should be paid to rapid temperature rise, balancing the flow of the inlet to be deodorized and the finished oil, and strictly controlling the deodorization time, etc. This is directly related to the technological level of oil refining equipment.
The refined oil is cooled, filled and sealed through automated packaging equipment for storage and sale.
