Sunflower oil is a kind of common edible vegetable oil in our daily life. Sunflower oil is extracted from sunflower seed.The sunflower oil pretreatment & pre-pressing machine we designed is fully adopted mechanical driven to make sunflower oil. What's more, sunflower oil pretreatment & pre-pressing machine belongs a production line which connects each single sunflower oil pretreatment machine together and realize the continuous work.

Different kinds of oilseeds have different oil content and physical properties. So the pre-treatment process varies slightly from one kind of seed to another. Today we mainly introduce the sunflower oil pretreatment process.
Sunflower Oil Pretreatment & Pre-pressing process flow chart:
Sunflower seeds---Cleaning machine---Husking Machine---Crushing Machine---Cooking Machine---Pressing Machine---Filtering Machine
Sunflower oil pretreatment process flow chart
First, using magnetic selector, stoner destoner and cleaning machine to remove metals, small stones , impurities from sunflower raw seeds.
Second, using husking machine to remove husks, separating screen to separate husk and sunflower kernel , here separating screen must not separate completel, if not it will be too slippery for sunflower oil pre- press.
Third, For big-size oil seeds, crushing reduces its size to benefit flaking, while for prepressed cake, crushing turns cake to proper size and creats better oil yeild for second press or solvent extraction. (Friendly reminder: Crushing is always necessary for soybean, peanut, palm kernel, coconut copra, tung oil seed, etc.)
Fourth, cooking sunflower seeds ready for oil pre-press
Fifth, pre-pressing sunflower seeds. Here only extract part of sunflower oil , most of oil residue still inside cake (about 12-16%), this part of oil residue will be extracted in sunflower oil solvent extraction process.
After sunflower oil pre-press process, we will get crude sunflower oil and pressed sunflower cake, the crude sunflower oil will be delivered directly to sunflower oil refinery plant for further processing, but the pressed cake will be delivered to sunflower oil solvent extraction plant for extracting more sunflower oil.

Features of the Sunflower Oil Pretreatment and Pre-press Machine designed by Henan Doing Machinery:
★ Easier to operate, easier to install and commissioning.
★ Need small investment, fewer land space, but with the complete function of the production.
★ Wide application that can process many other kinds of vegetable seeds and nuts, such as rapeseeds, cotton seeds, sunflower seeds, corn germ, palm kernel, sesame seeds and so on.
★ Need fewer labor than the single machines, only 2~3 persons can run the whole line
★ The semi-continuous can avoid the unstable material feeding caused by manual and can make the worker safety more under the higher temperature working situation.
