Palm oil refining machine

Process flow of palm oil refining machine:
Extracted palm oil, filtration, degumming, vacuuming drying, decolorization, deodorization, palm first grade oil
Introduction of palm oil refining process line:
Impurity removal. Impurity of extracted palm oil must be removed in order to reduce losses and increase yield of palm oil in palm oil refining process. Crude oil filter can remove impurities, control impurity of extracted palm oil under 0.2%, thus improve degumming efficiency.

Degumming process of palm oil refining machine.
Intermittent process preheats palm 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 process of palm oil refining machine.
Heat degummed vegetable palm 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 process of palm oil refining machine
Degumming of palm 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 palm oil and improves oil stability.

Deodorization process of palm oil refining machine
Control oil temperature to 250 ~ 270 ℃ when decolorized palm 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.
