Groundnut oil is one kind of very common vegetable oil in many countries, and the method of making groundnut oil is easy, too. Generally, groundnut need husking, because the groundnut shell has no oil content at all. You can remove the groundnut shell by hand if you have small amount of groundnut, and then using the home-used groundnut oil extraction machine to extract groundnut oil. Like this machine are not expensive. And you can buy it in your local area or on the internet.
However, if you don't want to make groundnut oil at home and eat by yourself, but to start the groundnut oil production business, you need consider more, like budget, land, where to buy groundnut oil production equipment, leaning more about the technology and process of groundnut oil production, etc.
The groundnut oil making process flow chart
As a professional manufacturer, Henan Doing Company can provide you high quality groundnut oil production equipment used in small scale, medium scale or large scale groundnut oil mill plant. And design the technology and process of groundnut oil production according to your needs. If you don't know the technology and process of groundnut oil production at all, our sales and engineers can explain for you. Next, I will introduce Doing Company's the technology and process of groundnut oil production briefly.
Step 1-- Groundnut seeds cleaning and preparation process
In this part, a series of equipment will be used, including cleaning machines(cleaning sieve, magnetic drum and destoner machine), husking machine, crushing machine, flaking machine, cooking machine. These machines can make the groundnut seeds for best condition and improve the oil yield.
Groundnut oil pretreatment and pressing machine
Step 2-- Groundnut oil pressing or pre-pressing process
Here, I need explain that in groundnut oil production industry, there are two methods to make groundnut oil. One is pressing method, the other is solvent extraction method. So groundnut oil expeller machine is used in groundnut oil pressing plant, and the residual oil rate in the cake is about 6-7%. The crude groundnut oil can be ate directly after filtration or sent to crude groundnut oil refinery plant to make refined groundnut oil.
The other is groundnut oil pre-press machine, which is used before solvent extraction plant, and the residual oil rate in the cake is about 15-20%. They have different inner structure, so have different functions.
Step 3-- Groundnut oil solvent extraction process
Four main system in groundnut oil solvent extraction plant
Solvent extraction method is suitable for large scale groundnut oil mill plant, more than 30 tons per day. The groundnut oil solvent extraction plant has four main systems: Solvent extracting system, D.T.D.C system, Miscella oil evaporation system, Cooling and recycling system. The best advantage of the solvent extraction is that its residual oil rate in the meal can be less than 1%.
Step 4-- Crude groundnut oil refining process
Through degumming, deacidification, decolorization and deodorization four process, the crude groundnut oil can be refined into final product oil, which can be sold to the supermarket. Doing Company can provie three kinds of groundnut oil refinery plants. As the following picture shows.
Three types of groundnut oil refinery plant we can provide
Step 5-- Groundnut oil filling process
Generally, large scale groundnut oil mill plant has the model blowing machine and a complete groundnut oil filling line. You can make your own bottle type and your own label. This is the final step in large scale groundnut oil mill plant.
Now, you must understand how groundnut oil is made in factory. If you really want to start groundnut oil production business, come to contact us. Henan Doing Company will provide you the best service.
