Physical pressing is a common method of extracting edible oil, so how to improve the oil yield of oilseeds in the physical pressing process?
The first thing we need to do is to choose better quality oilseeds, do a good job of pre-treatment of oilseeds before pressing, and choose a suitable edible oil press.
1、Choose high quality oilseeds
Good raw materials is the first step to quality oil, we should avoid choosing contaminated, moldy, or not mature oil seeds, otherwise it will not only affect the oil, but also affect the quality of the final cooking oil.
2、Pre-processing of oilseeds
In the oilseeds for pressing oil before we should be corresponding pre-treatment of oilseeds, so that it reaches the best oil state, such as:
1> Cleaning, to remove the adulteration of stones, debris and dust and other impurities
2>Crushing, to achieve the right volume
3>flaking, the oilseeds are pressed into flakes by the flake roller, which has a larger contact area with the solvent and a higher oil yield.
4>Expanding, the oilseeds are inactivated by various enzymes inside the oilseeds after expanding, so as to increase the oil yield.
5>cooking, the internal structure of oilseed flakes will be changed after steaming and frying, so that more oil can be produced faster and more in the subsequent process.
Oilseed pretreatment equipment includes oilseed cleaning machine (vibrating screen, magnetic separator, stone remover), crusher, embryo rolling machine, expanding machine, cooker, etc. These equipments can ensure the pretreatment of oilseed, so that the oilseed is in the best condition, suitable for pressing and ensure the maximum oil yield of the oilseed.
3、Choose the right oil press machine solution
All the previous work is for the service of pressing, a suitable oil press can improve the oil yield and oil quality significantly. The edible oil press machine of Henan Siwei Company adopts high quality materials, good quality, low price, high oil yield, which is the most widely used machine in the market at present, and we have a lot of equipments to meet the different production needs of customers and free design the edible oil production solution for you.
