The squeezing method is also called "physical squeezing method", which is to squeeze out the oil in the oil by external force, and other chemical solvents are not applicable, so as to avoid the residue of organic solvents in the oil.
The pressing production process retains the reasonable ingredients in sunflower seeds to a large extent - polyunsaturated fatty acids, protein, dietary fiber, vitamins, trace elements and other nutrients that are beneficial to the human body, and are more suitable for special supplements for the human body health care.
Production process of sunflower oil pressing method:
Screening → cleaning impurities → shelling → crushing → steaming and frying → pressing → pressing crude oil→ coarse filtration → fine filtration → low temperature crystallization and growth→ low temperature filtration → sunflower oil
(1) Material selection: screen sunflower seeds, the oil content of which is 30% to 50%;
(2) Impurity removal: Use cleaning sieve and demagnetizer to remove iron, stone, grass, soil and other impurities in sunflower seeds;
(3) Stir-frying: Add sunflower seeds into the drum frying pan to heat them evenly, and then roast them. The roasting conditions are as follows: temperature 160°C, time 50 minutes, rotating drum frying pan 20-25 rpm/ point;
(4) Cooling: Use a fan to cool the roasted sunflower seeds, and reduce the temperature of the sunflower seeds to 45°C within 15 to 20 minutes, then place them in a cool place and spread them into a layer of sunflower seeds with a thickness of no more than 5cm. At the same time, prevent the pollution of dust and sundries, etc., and obtain raw materials after natural cooling to room temperature;
(5) Crushing: Weigh the raw materials and crush them with a steel mill, then put them in a clean container to obtain a paste-like sludge;
(6) Mixing: Add the paste sludge into the mixer, and add water to stir evenly, wherein the amount of water is 8% to 10% of the mass of the raw materials in step (5);
(7) Pressing: Wrap the mixed material with a clean filter cloth according to the mold. The diameter of the mold is 60cm and the thickness is 10cm. Then press it in a hydraulic oil press. The pressing condition is that the pressure is ≤ 80MPa, the pressure rise rate is 20MPa/hour, so as to obtain crude oil;
(8) Filtration: Filter the crude oil through a centrifugal filter to remove impurities in the crude oil.
