High oil yield sunflower oil extraction machinery

These machines are used for pretreat the sunflower oil before pressing or solvent extraction. They are very important for the sunflower oil processing plant.

First, use magnetic separator, de-stonner and vibrate cleaning sieve to remove metals, small stones, impurities from sunflower raw seeds.

Second, use husking machine to remove husks, separating screen to separate husk and sunflower kernel, here separating screen must not separate completely, or it will be too slippery for oil pre- press.

Third, cooking sunflower seeds are ready for oil pre-press.

Fourth, pre-presse sunflower seeds. Here only pre-press part of sunflower oil, oil residue inside cake (about 12-16%) will be extracted in oil extraction process. After pre-pressed, the crude sunflower oil will be delivered directly to sunflower oil refining, and pressed cake to oil extraction.

Main Technical Data of our Sunflower Oil Making Machine:

First, hydrated degumming, mainly is to remove phosphatide inside crude sunflower oil in order to reduce oil loss and improve quality of oil .

Second, alkali refining, using alkali to neutralize free fatty acid with by-product of soapstock, which is used for making soap.

Third, decoloration using bleaching clay to absorb darker colorant inside crude oil.

Fourth, deodorization is using high temperature to remove the impurities with bad smell .

Fifth, dewaxing is using low temperature to freeze wax inside refined oil and then separate wax with vibrating screen.

Sunflower oil refining machine can convert the crude sunflower oil into refined sunflower oil, and it is necessary for a large scale sunflower oil processing factory.
