We supply small scale sunflower oil press machines for home or village use, large scale production oil sunflower seeds screw oil pressing line and sunflower oil refinery lines for commercial production factory use.
Sunflower oil production line includes:
sunflower seeds→cleaning→shelling→Kernel shell separation→crushing→flaking→cooking→prepressing→crude sunflower oil →cake
1.Cleaning process : Use vibration cleaning sieve and magnetic selector to get better cleaning effect.And This step is mainly to clean the big impurities ,like the stone, big dust , iron etc.
2.Crushing Process: This Process is mainly to crush the peanut , as the peanut is big ,it is not easy to press .We must crush the peanut to 6-8 pieces,then we need to peel .The rate of peel is about 90%.
3.Flaking Process : After crush and peel ,we need to flake the crushed sunflower , which make the cell wall of sunflower broken . And we flake the sunflower to 0.55 mm thickness .Then it is useful for the oil extracting..
4.Cooking Process: After the flaker,we need to cook the flaked sunflower , control the moisture at 5-7% ,the temperature is 110-115degree.
5.Oil-pressing : After all the pretreatment , pre- press the sunflower , the oil can be extracted about 76% .
6.Primary Oil Filtering Process: after the oil pressing, the crude oil will be primary filtered and for store to tank or for next process of oil refinery.
Generally, large scale sunflower seeds oil pressing line has two parts–sunflower seeds preparation and sunflower seeds oil pressing. Specifically speaking，the whole sunflower seeds preparation and oil pressing line include sunflower seeds cleaning, dehulling, nut&shell separating, flaking, cooking, pressing seven steps. Our Company can manufacture 30-2000tpd sunflower oil pressing line and provide turn-key project service for customers.
The crude edible oil obtained from oil expellers or solvent extraction contains impurities such as phosphatides, free fatty acids (FFA), pigments, off-flavor, etc. Oil Refining is a series of process to remove these impurities. After refining, the flavor, color and smell of edible oil is improved, the stability is improved which is good for long time storage, the smoke point of oil is increased. We provide 1-20tpd batch type edible oil refinery plant ,20-50tpd semi-automatic edibel oil refinery plant and 50-500tpd fully edible oil refinery plant for you. Besides, 1-5T/D edible oil refining line and 20T/D edible oil refining line are also available.
The feature of sunflower oil pre-press machine:
1. High capacity, less installation space, little power consumption and simple control & maintenance.
2. Pre-pressed cake, being loose but not crushed, is helpful to solvent penetration.
3. The percentage of oil and water content in cake are suitable for solvent extraction.
4. The sunflower oil got from the sunflower oil pre-press machine is of higher quality than that obtained by single pressing or single solvent extraction.
