exhaust edible vegetable oil extraction system

Exhaust edible vegetable oil extraction system

Soybean oil is one of the most popular in the world. We provide all machines necessary for a complete soybean oil plant, including pre-treatment machines, solvent extractors, refinery machines, etc.

Solvent extraction

Oils and fats in soybean flakes can dissolve in certain solvent. Therefore, we can immerse pressed fakes in solvent to extract oils and fats. Then remove solvent from wet meal, strip solvent from miscella, and recycle solvent.

Extraction

We’ve percolation extractor, immersion extractor and rotocel extractor, etc., as shown below. The solvent pumps in extractor will continuously spray solvent and soak the soybean flakes in it, so that oils and fats can be dissolved. After that, you get wet meal and miscella (mixed oil and solvent).

Wet meal treatment

Desolventizer toaster with integrated dryer-cooler(DTDC) is a system for separating solvent from the wet meal. We've vertical desolventizer toaster, horizontal desolventizer, flash desolventizing system and low temperature desolventizer, etc., as shown below.

Miscella treatment

After extraction, filter the miscella, send it to two evaporators successively, and then to the stripping tower. We’ve raising film evaporator, vapor separator, negative evaporator, normal evaporator, etc. For stripping, we’ve tubular stripping column, disk stripping column, plate stripping tower, filling steam stripping tower, etc. After evaporation and stripping, you get crude rice bran oil and desolventized meal. This meal can be used to produce feeds. The crude oil needs to be refined.

Solvent recovery

The solvent vapour from wet meal and miscella will be collected by condensers to be reused. We’ve pipe bundle condenser, spraying condenser, contact condenser, etc., as shown below.

Extraction parameters

Capacity:300T/D

Residual percent in the cake: less than 1%

Solvent consumption: less than 2kg per ton needed for each raw material

Moisture and volatile in the crude oil: less than 0.3%

Electricity consumption: less than 15 kw.h consumed for each ton raw material.

Steam consumption: less than 280kg steam consumed for each ton raw material, if the pressure is 0.8Mpa.

The moisture of finished cake: less than 13%, it can be adjusted according to your needs.

The residual solvent in the finished cake: less than 300PPM, which is qualified by the experiment.

Features of our desolventizer

1)It can raise the using value of the cake by passivating and destroying the anti-nutrition elements such as urease and trypsin in the cake.

2)It can well control the degeneration degree of the protein in the cake, and can effectively raise the NSI index.

3)It can well adjust the color, the smell and the granule size of the cake.

4)It can better reduce the reside solvent in the cake, and can adjust the moisture in the cake, which can ensure the safe use of the cake and the least consumption of the solvent during the producing.

The features of our negative evaporation

1)High efficiency, thorough desolventizing, low consumption of solvent in the crude oil.

2)The reside steam in the steam jet pump and the used steam of the desolventizer can be use as the heat source of the first steam, which can save energy,at the same time,it can reduce the land square needed for the condenser, then save money.

3)Because of the lower temperature needed for stripping, the crude oil is clearer, better quality, less reside solvent.

Solvent Extractor Advantages

1) The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither and thither on the material layer and ensure the concentration gradient between several sprays.

2) Immersion area appears in each lattice, which can help achieve better immersion effect.

3) The chain box is supported by track and can prolong the service life of screen deck by not touching it.

4) The towline extractor is driven by world exhaust edible vegetable oil extraction system double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.
