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

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.
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).
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.
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.
