Loop type extractor in soybean oil extraction

Loop type extractor

Loop type extractor has better extraction effect. There is a bending section in this extractor, where the materials could be flipped and drained. So its extraction time is the shortest of the three.

Its bed of materials is thin and adapts to different materials. This extractor occupies little space but has lots of wearing parts, demands high precision manufacturing and also requires high strength chain, which cause a higher cost.

It is easy to transport and install. Feeding and discharging equably and there is no bridging happens.

SOLVENT EXTRACTION SECTION The seed after relevant preparation in the pre-treatment plant (cleaning, de-hulling, cracking, cooking, flaking and pressing) feeds the extractor where it is laid on a filtering belt with automatic level control devices. The filtering belt moving from one to the other side of the extractor charges the oil cake coming from the feeding hopper, submits the seed cake to solvent shower and discharges the de-oiled cake into the extractor discharging hopper from which the same by screw conveyor and chain elevator goes to the next step. 

The solvent (Hexane) enters the extractor in the opposite side of the oilseed, it is sprayed on the seed belt, flows through the same and is recovered in the underneath hopper from where it is pumped into the next sprayer step; the number of sprayer steps changes depending on the capacity of the plant. The solvent with extracted oil is pumped to the next step. Solvent is enriched with oil, as it goes through the different steps. 

Huatai can propose different types of Extractor Equipment : Rotocel extractor, Loop type extractor and Drag chain extractor. the choice of which depends on specific applications beside the targeted plant capacity.
