A fine filter screen 31 and an activated carbon layer 32 are fixedly connected inside the decolorization tank 3, and the palm oil is filtered and deodorized by the fine filter screen 31 and the activated carbon layer 32. A heat transfer oil pipe 21 is fixedly connected inside the deacidification tank 2 and the decolorization tank 3, and heat transfer oil is injected into the heat transfer oil pipe 21 to filter and deodorize the palm oil. The palm oil inside the acid tank 2 and the decolorizing tank 3 is heated to evaporate the water in the oil.

The circulation mechanism includes a circulation pipe 61 fixed on the degumming tank 1 and the deacidification tank 2. A third three-way valve 62 is fixedly connected to the circulation pipe 61. One end of the third three-way valve 62 is fixedly connected to a connecting pipe 63.

The degumming tank 1 or the deacidification tank 2 is extracted by starting the feed pump 6. The palm oil inside is circulated under the action of the circulation pipe 61 and flows back into the degumming tank 1 or the deacidification tank 2. The flow direction of the palm oil is changed by starting the third three-way valve 62 to make it flow into the connecting pipe 63, so that the palm oil is injected into the lower tank body.

[0027] Working principle: palm oil is injected into the degumming tank 1 through the injection pipe on the degumming tank 1, and the palm oil is preliminarily filtered through the primary filter 11 to filter out suspended impurities in the oil. The oil in the degumming tank 1 is extracted by starting the feed pump 6, and the oil is circulated under the action of the circulation pipe 61. During the circulation process, the phospholipase in the medicine box 4 is extracted by starting the dosing pump 5 under the action of the medicine delivery pipe 41, and the medicine is injected into the oil circulating in the circulation pipe 61 to mix with the oil. The phospholipase converts the non-hydratable phospholipids in the oil into hydrated phospholipids for degumming. After a period of rest, the feed pump 6 and the third three-way valve 62 are started to make the oil in the degumming tank 1 flow into the deacidification tank 2 through the connecting pipe 63, and the deacidification tank 2 is hydrated by injecting heat transfer oil into the heat transfer oil pipe 21. The oil inside is heated, and the above-mentioned cycle process is repeated. The trisodium phosphate inside the other reagent box 4 is mixed with the oil inside the deacidification tank 2 by controlling the first three-way valve 42 and the second three-way valve 51 to neutralize the acid of the palm oil inside the deacidification tank 2 for deacidification. After a period of rest, the feed pump 6 is started and the third three-way valve 62 is controlled. The oil is injected into the decolorization tank 3 under the action of the connecting pipe 63, and the rotating rod 8 is driven to rotate by impacting the impeller 81. During the rotation of the rotating rod 8, the discharge port of the injection barrel 7 is indirectly opened through the baffle plate 83 to allow the white clay inside the injection barrel 7 to be indirectly poured into the decolorization tank 3 to decolorize the oil. The palm oil is filtered and deodorized by the fine filter mesh 31 and the activated carbon layer 32.
