This continuous peanut oil refining line is designed for continuous operation. Continuous peanut oil refining process always including the following sections: degumming, deacidification, bleaching, deodorizing. In the entire peanut oil refining process, a lot of refining equipments will be used, such as crude peanut oil storage tank, Phosphoric acid tank, centrifugal equipment, bleaching tower, vacuum filter, deodorization tower, FFA catcher, steam boiler, heat contductive oil system, etc. The whole continuous peanut oil refining line adopts the full automatic control system, ensuring the whole peanut oil refining process precision, as well as energy saving, low consumption etc.

Henan Doing Company is a leading designer, manufacturer and exporter of edible oil refinery plant in both continuous type vegetable oil refinery plant and batch type vegetable oil refinery plant. Next you will see the continuous peanut oil refining process.

It is very essential that the crude oil obtained from oil press workshop and solvent extraction workshop get refined in the vegetable oil refinery plants before it is utilized directly. Our continuous peanut oil refining machine line gives color uniformity and appealing quality to the oil by removing unpleasant smell and undesirable factors from the oil.

Functions of continuous peanut oil refining process:

Peanut oil refining process can remove the different kinds of impurity in the Crude Edible Oil.

Peanut oil refining process can improve the oil quality. Such as the taste, the smell, the colour, the acid value, etc. which affects human consumption.

After peanut oil refining process, the cooking oil is not easy to Oxidize and quality can be promised to store for longer time.

Mian equipment of continuous peanut oil refining machine

Mian process of continuous peanut oil refining machine line:

1. Crude peanut oil degumming process

2. Crude peanut oil deacidification/neutralization process

3. Crude peanut oil decolorizing process

4. Crude peanut oil deodorization/distillation(deodorizing unit) process

1>Degumming：Degumming removes gums as preparation for subsequent refining processes.

2>Deacidification：Deacidification removes FFA (free fatty acid) in crude oil.

3>Decolorization: Decolorization removes pigments in crude oil by adding white clay, which can improve the oil quality.

4>Deodorization : Deodorization removes odor in crude oil, which can improve the flavor, stability, color and quality of the oil.

Working principle of continuous penaut oil refining line:

Calibrated crude oil is pumped to pipe filters; then filtered oil is sent to heat exchanger. Heated oil is mixed with acid in the mixer before going to the reaction tank. After reaction and cooling, the oil enters another mixer to mix with caustic alkali liquid to neutralize. The neutralized oil enters the centrifugal to separate soap from peanut oil. Separated oil still contents some quantity of soap that should be removed. By mixing with hot water, the oil is washed. Then a centrifugal is used to separate the water with residual soap from oil.

De-gummed and neutralized peanut oil is pumped into vacuum drier, and then dried oil is cooled by a heat exchanger and sent into a storage tank. De-gummed and neutralized oil is sent to bleaching section to bleach. Oil to be bleached is pumped to mixed tank and heating tank separately. A proportion of oil to be bleached is pumped into a mixing tank to mix with dosed bentonite, and another part of oil to be bleached is pumped to the heater. The mixture and the heated oil go into the bleaching tank to de-colourize. Consequently, the mixture of oil and bentonite is pumped into leaf filter to remove deposable bentonite.

Parallel leaf filters make it possible to perform continuous operation of bleaching. Filtered oil is pumped into the storage tank after being cooled in a heat exchanger and filtered safely.

Deodorization section is to remove the unpleasant odor from bleached peanut oil. Certain amount of citric acid liquid is added to the oil to be deodorized to chelate the metal ion in oil. The oil then enters a deaeration tank to remove air in the oil by high vacuum. Then oil is pumped into a heat exchanger to raise temperature with hot deodorized oil; peanut oil is heated further by mineral oil to raise the temperature to 240℃～265℃. The heated oil goes into the deodorizer tower from the top of flash sector; mixes with the rising steam to strip low molecular organic compound. Oil flows down to the bottom of tower to perform pigment decomposition. The flavor of oil is improved. Oil is pumped into the main sector of deodorizer tower to further remove free fatty acid (FFA). The vapor goes into FFA stripping sector to exchange heat; the condensed low molecular compound goes into the recycling FFA stripping system. The deodorized oil from the bottom of deodorizer tower is pumped out to exchange heat with oil that comes out from the deaeration tank, and then goes to a cooler. Finally, oil is filtered by polished filter. Final product is sent to final oil tank, which can be sold as first class product oil.
