cooking soybean oil refining machine

Basing on the traditional oil refining technoloLD, Shandong Leader'E Grain and Oil Machinery Co.,Ltd has developed the latest combined packing layer plate deodorization soft tower and the physical and chemical mixed refining technoloLD for crude oil of any quality. Moreover, a series of advanced technoloLD and equipment are used, such as super wet deguming, bleaching earth automatic metering, negative pressure decoloring, high vacuum steam jet deodorization, deacidification, winterization dewaxing etc..

Main Processes Introduction of cooking soybean oil refining machine

Hydration Deguming & Alkali Refining Deacidification Process of cooking soybean oil refining machine

Neutralization: the crude oil is output by the oil feed pump from the oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids.

Washing: there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. Vacuum drying stage: there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.

Continuous Refining Decoloring Process of cooking soybean oil refining machine

Continuous Decoloring Process Features:

1. The oil fully contacting with the decolorant can improve the decolorization efficiency and reduce the usage of decolorant;

2. The continuous and uniform material flows will balance the decoloring time and avoid the recovery of grease oxidation and acid value.

3. The special mixing structure of decoloring tower won't cause the material dead area, which can avoid the LDorbent sedimentation and pipe blockage.

4. The continuous airtigLD efficient filtration equipment has realized the automation of cake discharge and reduced the labor intensity.

5. The advanced drying technoloLD can reduce the oil content in filter cake.

Continuous Refining Deodorizing Process of cooking soybean oil refining machine

The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. The upper layer of combined deodorization tower is the packing structure which is mainly used to remove the odor producing components such as free fatty acid (FFA); the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler.
