1. Craft flow for groundnut  oil pressers

Main Equipments: 

1. groundnut: It’s one of main oil seeds from human. It’s used to make groundnut oil around the world.

  The oil content in groundnut is about 35%.

2. Magnetic box: Clearing the iron impurity which might be in the groundnut. The iron impurity will be harmful to the following machines, so we need take the iron impurities out. 

3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going through this part, most of the impurities are moved from groundnut.

4. husking:this can help improve the oil yield from groundnut,and reduce wear to the machine.

5. flaking:  It is the process of making use of the mechanical action to flake the groundnut into flakiness. After flaking, the materials is becoming thiner thank before, it is good for absorb moisture and heat in cooking process , and it is much easier for getting groundnut oil in the oil press process.

6. Cooker: This machine can adjust the water content of the groundnut. It’s also good for the press and oil extraction section.

2.Craft flow for pressing of groundnut oil pressers

Press: The press machine is used to take oil out of the groundnut . 

After pressing,we can get crude groundnut oil,and the oil residual in the cake is about 5-7%.

3. Craft flow for refinery of groundnut oil pressers

Crude groundnut oil → degumming and deacidification→ decolorization →deodorization → refined  groundnut oil.

Main Process: 1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the groundnut oil. 

One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for capacity from 30-2000T per day.

2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the groundnut oil according to the requirement of your market.

3. Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined groundnut oil.
