Sunflower oil equipment manufacturers

Let's have a look at the oil extraction process of sunflower seeds:

Step 1 heat treatment:

Heat treatment is one of the most important procedures in the process of oil extraction. Materials pressed after heat treatment are called hot pressing, while those not pressed are called cold pressing. Sunflower seeds are mainly hot-pressed, and the effect of heat treatment has a direct impact on the smooth process of oil production, oil yield and the quality of oil products and cake. It is better to select oil sunflower seeds one month after harvest. The hot pressed oil sunflower seeds can be pressed when they are evenly stir-fried until they are 70% ripe. Without stir-frying, the oil yield will be affected. Cold pressing refers to the direct physical pressing of raw oil sunflower, so that the resulting oil has little flavor and high moisture content, which is difficult to preserve. "Three squeezed, seven Fried (steamed)" according to the characteristics of sunflower seeds developed by our company special steamed frying pan, sunflower seeds to achieve good separation of oil molecules.

Step 2: Press:

Oil press circle pressing bar is saw-toothed curve and cone, rapeseed, when being squeezed by squeezer push and squeeze squeezer and squeeze the wall space in the cage size changing, at the very back of the press cage because of the article have arranged round the press cage of the lining is zigzag and billet material alternately by squeezing and relax here, is expected to continually adjust the structure of the billet, with even turn, make not be squeezed out of the oil or extract oil less material billets have more opportunities to fully by squeezing. The small and medium-sized sunflower seed oil press developed by our company serves all kinds of sunflower seed production customers.

Step 3: Filtering:

The edible oil extracted and processed by a full-automatic sunflower seed oil press contains certain oil residues. In order to improve its purity, we use an oil filter to filter the oil residues so as to obtain pure edible oil that can be used directly. We generally recommend open oil mill friends, choose air pressure filter, this equipment with heating function, after treatment, the oil becomes "cooked oil", less oil foam after filtering, and can filter out most of the oil residue, so that the oil is clear and bright, oil fragrance overflowing.
