We undertake turnkey project solutions for the complete Groundnut Oil Mill Plant. We provides small to large peanut oil extraction plant ranges starts from 5 TPD to 140 TPD. If you are thinking to start a groundnut oil manufacturing plant, or have any questions about peanut oil extraction and refining process, welcome to contact us.
The groundnuts also known as peanut or earthnut. The oil content in the peanuts is between 20% and 30% depending on the variety. The major groundnut producing countries in the world are China, India, Nigeria, Senegal, Sudan, Burma and the United States of America etc.
The requirement of machines and equipments for peanuts oil mill usually depends on the various aspects such as processing raw materials, required pressing capacity, production cost budget and other detailed information. So don’t hesitate to get in touch with us to get a customized business plan and project cost list. Here we have listed some of the common machines required to start a groundnut oil mill plant including Boiler, Bucket Elevator, Screw Conveyor, Decorticator, Seed Cleaner, Cooker / Kettle, Oil Expeller, Crude peanut oil storage tanks, Filter press machine with Pump, Filtered oil storage tanks and Volumetric filling machine.
Cleaning: This process adopts cleaning sieve or other cleaning machine to remove the stones, metals, and other impurities from the groundnuts. The less of the impurities in the groundnuts after screening, the better of the groundnut oil extraction process. The impurity rate is less than 0.1%.
Peanut Shelling: This process adopts peanut sheller to remove the hard shell of peanuts and get the peanut kernels with red skin automatically. The kernel content of shell was less than 0.5%.
Decorticating: This process adopts decorticator to remove the red skin of the groundnut kernels automatically. The peeling rate is up to 90%.
Crushing and Flaking: The groundnut kernel can be crushing into 4~6 pieces by crushing machine. Then, using the flaking machine to ground the groundnut kernels. It is better to grind out the green kernels 0.3 ~ 0.5 mm thick.
Cooking: Adjusting the condition of the groundnut flake pieces with cooker. The moisture is about 5~7% and the temperature is about 110˚C to 115 ˚C.
Pressing: Using screw oil press machine to press the oil out. The oil yield is about 76~78% for the first time. And the oil yield is about 12~14% for the second time. (Read more about Peanut Oil Press Machine >>)
Filtering: The obtained crude groundnut oil then is going through the filter press machine to remove large organic imporutities and get the pure crude groundnut oil.
Refining: For better quality of final groundnut oil, it is better to equip the groundnut oil mill plant with edible oil refining machine to remove all the useless and harmful impurities, color and odors. (Latest Post: Edible Oil Refinery Plant Cost >>)
