There are two ways to extract oil from oilseeds. One is to use an oil press for physical pressing, which retains the natural fragrance of the oil. The second is to use cooking oil solvent extraction machine for chemical extraction. The solvent extraction method is a production method that uses the principle of solvent and oil dissolution to extract oil from oilseed cakes. After extraction by solvent extraction, the residual oil rate of the oil cake is less than 1%, which improves the oil yield. Let's take a look at the equipment used in these two methods.
1. Press to make cooking oil
If your processing capacity is small, we have three types of oil presses, there are cold presses, automatic temperature control oil presses, air pressure filter combination oil presses.

The cold press machine only has the function of extracting oil, and is often used for cold pressing to retain the nutrients in the oil. The automatic temperature control oil press comes with a roaster, which can automatically adjust the oil output temperature and improve the oil output rate. Air pressure filter combination oil press comes with a roaster and two vacuum filter barrels, which can realize the integration of cooking and filtering, which is more convenient.
If your processing capacity is large, we also have the whole production line for you to choose, which includes machines such as cleaning machine, kernel shell separator, flaking machine, roaster, oil press and filter, etc. The specific production process is as follows:
(1) Use cleaning machine to remove impurities in oilseeds. Common cleaning machine includes magnetic separators, cleaning screens, destoner, etc.
(2) Separate the oilseed kernel and shell with a kernel shell separator.
(3) Using flaking machine and roaster to adjust the temperature, humidity and internal structure of oilseed is more conducive to oil production.
(4) Squeeze the oilseeds with an oil press to get oil, and if you want to get more oil, you can perform secondary pressing.
(5) Use a filter to remove impurities and part of the water in the crude cooking oil.

2. Solvent extraction to cooking oil
The production of cooking oil by solvent extraction also requires cleaning machine, shelling machines, flaking machines, roaster, etc. to process oilseeds, adjust the internal structure of oilseeds, and improve the production efficiency of oilseeds. Then, a prepress is used to obtain the oil and filter cake. The filter cake needs to be transported to the solvent extraction plant for further cooking oil production. Solvent extraction includes extraction section, miscella evaporation and stripping section, dissolving baking powder section, and solvent recovery section.

If you want higher quality cooking oil, you can use cooking oil refining machine to refine crude cooking oil. Henan Glory Company specializes in the development of cooking oil extraction machine. Our company was established in 2011. It is an enterprise integrating engineering research and development, equipment manufacturing and installation, engineering contracting, technical services, and international trade. We are mainly engaged in cooking oil pretreatment, pressing, refining, solvent extraction, fractionation, winterization, dewaxing, etc. If you want to engage in cooking production business, please feel free to contact us.
