We all know that we can extract edible oil by solvent extraction method, so what are the characteristics of solvent extraction method? Under what circumstances is it suitable to choose the solvent extraction method? Then we will introduce you in detail.
Solvent extraction plant
Features of solvent extraction workshop:
1. Lower residual oil rate
Generally speaking, the use of Henan Doing's cooking oil pressing machine can ensure that the residual oil rate is less than 8%. But if you choose to extract edible oil by solvent extraction, you can make the residual oil rate less than 1%. This way, you can get more edible oil. After leaching, we can get the meal and edible oil, and the edible oil is subjected to subsequent processing. Meals can be sold as animal feed.
2. Greater demand for capacity
In consideration of economic efficiency and cost, if your processing capacity is greater than 20tpd, we recommend you to use the solvent extraction method. Because the solvent extraction process requires many machines including extractor, DTDC system, mixed oil evaporation and stripping system, and solvent cooling system. The whole system is more complicated and requires higher craftsmanship, so the cost is higher.

3. It needs to be refined before eating
The edible oil obtained by solvent extraction must be refined before it can be eaten, and the crude edible oil obtained by pressing can be eaten directly. Therefore, the solvent extraction is suitable for large capacity edible oil production lines. And the edible oil obtained after refining is of higher quality and can meet national food safety standards.
In general, more edible oil can be obtained by solvent extraction. However, it has requirements for process capacity and refining, and is more suitable for edible oil extraction plants with a processing capacity greater than 20tpd. If you want to build an edible oil extraction plant, you can contact Henan Doing. We will provide you with a high quality edible oil extraction machine.
