Storage 

Oil materials’ storage process includes acceptance, metering, drying and storage. The impurities of materials contain the plant stem , mud block, loading and unloading of metal . To make the storage more safe, the initial clearing operations before the storage is necessary .The initial clearing operations usually include screening, magnetic selection, wind, etc., to remove he large miscellaneous, small miscellaneous, iron miscellaneous, light miscellaneous and dust. New oil materials usually are of high moisture content, generally it is necessary to reduce moisture to 13% before  warehousing, and the materials' drying is finished  in the drying tower .

Storage Bunker Type: House type warehouse and Vertical type silo.

Pre-treatment

Main equipment

Cleaning equipment,stone removal equipment,shelling equipment, crushing equipment, rolling equipment,expansion equipment,etc

Advantages

• Using thermal technology,low energy consumption；
• Double crushing peeling and the peeling rate is above 85%, the peel residual oil is below 1.5%；
• Large capacity of the soybean hull and flexible production；
• Be able to produce different levels of soybean meal，including the crushing section；
• It can choose the puffing process；
• The entire production line can be used to fully automatic control.

Press Technology 

Pressing process refers to press oil from oil plants with the help of the external mechanical forces,the main sections include:steaming and roasting,pressing as well as crude oil residue removal.

Advantages

• Using simple technologies and supporting facility
• Be well-adapted to oil plants and flexible production
• Be superior to quality, and with shallow color , lustre, as well as pure taste.

Refining Technology 

Degumming is to remove the peptizing impurities in crude oil,mainly to remove phospholipids, in addition to the phospholipid binding protein, saccharide, mucus, trace metals, etc.. the peptizing impurities not only affects the stability of oil, but also affects the process effect of oil refining and deep processing.Such as in  the course of alkali refining,it is easy to form emulsification, increase the difficulty of operation, increase the consumption of grease refining and auxiliary materials , and to reduce the quality of soap feet ;In the course of Decolorization,it increases the consumption of adsorbent,reduces the decolorization effect;In the course of deodorization, the color of the oil is deepened by the carbonizing colloid.

Deacidification removes the free fatty acids from the crude oil to lower the acidity of the oil. Free fatty acids is easy to oxidation, and make the oil to produce irritating odor and then affect the flavor and the use value of oil.Unsaturated acid can accelerate the oxidation of oils, prevent oil hydrogenation smoothly and corrosion equipment. As free fatty acids are the root cause of deterioration of oils, So the less free fatty acids in oils, the better.
