Problems solved by technology

[0004] In view of the unbalanced distribution of solid phase and liquid phase in the centrifuge of the prior art, which easily causes the phenomenon of oil leakage, the present invention provides a method for optimizing soybean oil refining production, which breaks the traditional thinking and changes the single washing method. Two times of washing to remove soap can effectively reduce the soap content of neutral oil, solve the phenomenon of oil run-off caused by the instability of neutral oil soap content, stabilize the quality of finished oil products, ensure the continuity and stability of production, and The washing water is completely recycled and reused, the residual oil in the washing water is recovered, and the refining rate is effectively improved and the production cost is reduced, so as to solve the above technical problems

Embodiment 1

[0044] (1) Heat the crude oil in the crude oil storage tank, heat the crude oil to 70-75°C, add phosphoric acid with a concentration of 75%, and the addition amount is 0.1‰, mix it, and then enter the acid delay tank, Carry out 40-60min delayed stirring.

[0045] (2) The acid-treated crude oil is mixed with alkali, and a liquid alkali with a concentration of 15% is added. After mixing, it then enters an alkali delay tank for 30-40 minutes of delayed stirring.

[0046] (3) Alkali neutralizes the processed crude oil, and then heats the neutralized crude oil to 80-85° C. through heat exchange, and then separates in a soap-removing centrifuge.

[0047] (4) The separated saponin enters the saponin tank, and the saponin tank enters the storage tank for storage in the tank area.

[0048] (5) The neutral oil obtained by desoaping and centrifugation in step (3) enters the neutral oil mixer, mixes with the washing water in the oil separation tank, and the reuse washing water addition i...

Embodiment 2

[0055] combine figure 1 , it can be seen that a device for optimizing soybean oil refining production includes a crude oil storage tank 1, a first hydration delay tank 7, and a second hydration delay tank 8, and the crude oil storage tank 1 is connected to a heat exchanger 2. The heat exchanger described above is a plate heat exchanger with good heat exchange effect, simple structure and easy to use.

[0056] Heat exchanger 2 connects acid mixer 3, and acid mixer 3 connects acid delay tank 31, and acid delay tank 31 connects alkali mixer 4, and the material outlet 45 of this alkali mixer connects alkali delay tank 41, and the alkali mixing The soda water inlet 43 of device connects alkali reaction tank 42, and alkali reaction tank water inlet 44 connects the water outlet 51 of sub-oil tank 5; Angle tank 62, the saponin tank 62 is connected to the storage tank 63, the oil outlet 64 of the desoaping centrifuge is connected to the neutral oil mixer 65, and the material outlet 66...

Embodiment 3

[0060] In conjunction with the device of Example 2, a method for optimizing soybean oil refining production of the present invention can be specifically as follows, and the detailed steps are as follows:

[0061] (1) Pass the crude oil in the crude oil storage tank into the heat exchanger, heat the crude oil to 70-75°C, add phosphoric acid with a concentration of 80%, and the addition amount is 0.09‰, enter the acid mixer for mixing, and then Enter the acid delay tank for 40-60min delayed stirring.

[0062] (2) The crude oil after the acid treatment comes out from the acid delay tank and enters the alkali mixer, while adding a concentration of 15% liquid caustic soda in the alkali mixer, after the alkali mixer mixes, then enters the alkali delay tank, Enter 30-40min delayed stirring.

[0063] (3) Alkali neutralizes the processed crude oil, then heats the neutralized crude oil to 80-85°C through a heat exchanger, and enters the soap-removing centrifuge for separation.

Abstract

The invention relates to the technical field of refining process optimization in grain and oil industry, in particular to a method for optimizing soybean oil refining production. The method has obvious effects on reducing soap content of neutral oil and increasing refining rate. The method comprises the steps: crude oil in a crude oil storage tank is subjected to heat exchange, the crude oil is heated to 70-75 DEG C, phosphoric acid with the concentration of 75-85% is added at an adding amount of 0.008-0.015%; then the crude oil is conveyed into an acid delay tank, and delayed stirring is conducted for 40-60 min. Traditional thinking is broken through, a single washing mode is changed, two times of water washing soap removing are adopted, the soap content of neutral oil is effectively reduced; the method can solve the problem of oil leakage caused by instability of soap contained in the neutralized oil, stabilize the quality of finished oil products, ensure the continuity and stabilityof production, completely recycle the washing water, recover the residual oil in washing water, and practically enhance the refining rate and lower the production cost, so that the above technical problems are solved.

Description

technical field [0001] The invention relates to the technical field of refining process optimization in the grain and oil industry, especially in reducing the soap content in neutral oil and improving the refining rate. Specifically, it is a method for optimizing the refining production of soybean oil. Background technique [0002] With the improvement of the domestic economic level, people's demand for edible oil is increasing day by day. As one of the main edible oils, soybean oil has always had a large market in China, and the refined soybean oil has a wide range of applications. At present, the refining processes of major domestic grain and oil companies are mainly divided into physical refining, chemical refining and mixed refining. No matter what kind of process, centrifuges are needed for solid-liquid separation, and centrifuges are also one of the important factors affecting the refining production line. . The principle of the centrifuge is to separate the impuritie...
