Main steps of pretreatment in corn oil making machine.
1. Magnetic box and cleaning screen
To move the impurities in the raw materials. This can help to protect the following machines.
2. Flaking roller
To make the corn germ into pieces with the thickness from 0.25-0.3 mm. This can help the corn germ heating well-proportioned and soaking well in the extraction section.
3. Dryer and cooker
Before the raw materials entering the extraction section, we need to adjust the water
rate by dryer. In this process, the water and temperature help to get crude oil easily
and improve the quality of cake and oil. After the dryer and cooker under 105-110
°C, the water content is 5-8%.
4. Pressing or pre-pressing
If the capacity under 30T and without extraction section, usually we will use pressing to get
crude oil. If the capacity is above 30T and the line with extraction section, we will use
pre-pressing to get parts of crude oil in the cake.
Main steps of extraction section in corn oil making machine.
1. Rotary extractor: this is the very important machine in extraction section. The function of this machine is to extract corn oil from the corn germ.
2. Toaster: This is the equipment to separate corn oil from the corn germ cake.
3. 1st, 2nd evaporator and stripping tower: The function of these machines is to separate oil and solvent.
4. Cooling system: Cooling system is important in solvent recycling. It helps to recycle the solvent, so the consume of solvent is little.
Through pretreatment and extraction, crude corn oil is got.
Then we will change the crude corn oil to refined corn oil.
Main steps of refinery section in corn oil making machine.
1. Neutralizing: This pot is used to degum and deacidify.
2. Decolorizing (bleaching) : The function of this part is to move the color of the oil. The color
of the oil can be controlled by yourself.
3. Deodorizing: This is the part to move the odor of oil.
