Oil Mill Fully Continuous Edible Oil Refinery

Sunflower oil refining machine

Description of sunflower oil refining machine:

Quantitive crude sunflower oil is pumped to pipe filters; then filtered oil is sent to heat exchanger. Heated oil is mixed with phodphoric 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 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 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.
