Peanut oil refined production equipment

Cooking oil pretreatment machine

Groundnut/Peanut oil pre-pressing production equipment introduction:　　We supply different pretreatment methods for oil plants with different oil content. Generally,for high oil plants.such as groundnut/peanut, rapeseed, cottonseed, first pre-press to the reasonable level and then extract.　　

1. Cleaning process in peanut oil refined production equipment: 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 in peanut oil refined production equipment: This crushing 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 in peanut oil refined production equipment: After crush and peel ,we need to flake the crushed peanut , which make the cell wall of peanut broken . And we flake the peanut to 0.55 mm thickness . Then it is useful for the oil extracting .　　

4. Cooking process in peanut oil refined production equipment: After the flaker,we need to cook the flaked peanut , control the moisture at 5-7% ,the temperature is 110-115degree .
5. Pre-pressing in peanut oil refined production equipment : After all the peanut oil pretreatment , pre- press the peanut , the oil can be extracted about 76% .

Peanut oil solvert extraction equipment

Groundnut/Peanut oil solvent extraction machine.

After pre-pressing process , the requirement of peanut cake : moisture is about 8%, the residual oil :18-22% .Use solvent organic solvent through soaking or spraying contact methods to extract oil from the cake. There is only less 1% oil content in meal after oil extraction machine .

Remark: The extraction workshop must be in a separate yard . This yard should be have at least 1.5 m high brick wall all around ,the walls is 12 meters far from extraction workshop. Fire district : at least 30 meters far from residential area, keep from fire .

Peanut oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.　The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction,will be pumped into oil refinery units to produce cooking oil at various grades.

These processes include neutralization (removing free fatty acid), degumming, decolorization (bleaching),deodorization.Then you can get first grade groundnut/peanut oil .
