Continuous groundnut oil refining plant

Continuous groundnut oil refining plant utilizes physical oil refining method to make extracted crude groundnut oil into first grade groundnut oil. The advanced equipped continuous groundnut oil refining plant is low refining loss rate, and high oil yield rate.

Groundnut oil refining process is to remove some substances that do harm to humanbeings or effect the soybean oil quality. Continuous groundnut oil refining plant can reduce refining losses and increase refined groundnut oil production quantity.

Degumming:

Intermittent process preheats groundnut 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 groundnut oil can remove grease in oil pigment to improve oil color, adsorption of aflatoxin and trace metals, phospholipids, other gum and other impurities. It ensures high quality of groundnut 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.
