Groundnut oil refinery plant is the main equipment of peanut/groundnut oil mill plant. Groundnut oil refinery plant can refine crude groundnut oil and get standard groundnut oil. We are able to supply professional groundnut oil refinery plant to meet different customer's requirements.

The oil obtained from pressing or solvent extraction process always contains impurities such as phospholipids, FFA, pigment, off-flavor and other impurities. In order to make the oil edible, the impurities must be taken out. So the groundnut oil refinery plant is necessary.

Groundnut oil refining process always including the following sections: degumming, neutralizing, bleaching, and deodorizing section. In the entire groundnut oil refining process, a lot of refining equipments can also be used, such as refining pot, bleaching pot, deodorization pot, vacuum filter, heat conduction oil furnace system, etc.

Working priciple of groundnut oil refinery plant:

Impurity removal.

Impurity of extracted peanut oil must be removed in order to reduce losses and increase yield of groundnut oil in peanut oil refinery process. Crude oil filter can remove impurities, control impurity of extracted peanut oil under 0.2%, thus improve degumming efficiency.

Degumming:

Intermittent groundnut oil refinery process preheats peanut crude oil to 80 ~ 85 ℃. The amount of water in crude oil bases on colloid content, and generally 3-5 times of the gum content, water temperature at 85 ~ 90 ℃ (5 ℃ higher than oil temperature). Finish water adding in 40-60min, along with 60-70r/min stirring, continue stirring 3-5min after adding water, and stand for precipitation 2-4h.

Vacuum drying:

Heat degummed vegetable peanut oil to 25 ~ 135 ℃, dehydrated into a vacuum dryer 20 ~ 30 min. Moisture of dehydrated oil is less than 0.1% (after degumming of crude oil via the oil contained in the 0.3% to 0.5 % of the water will affect the adsorption capacity of bleaching clay section).

Decolorization:

Degumming of peanut oil can remove grease in oil pigment to improve oil color, adsorption of aflatoxin and trace metals, phospholipids, other gum and other impurities. Decolorization of groundnut oil refinery plant ensures high quality of peanut oil and improves oil stability.

Deodorization:

Control oil temperature to 250 ~ 270 ℃ when decolorized peanut oil enters into deodorizer, in direct steam injection, the free fatty acids, ketones, aldehydes and other impurities are removed from the oil, the thermal decolorized action also occurs, and the pigment composition is cleaved distilled from the oil. Deodorized vacuum (absolute pressure) controlled at 266 Pa, the deodorization time is about 2h.
