How to do the process steps of hydration and degumming of soybean oil refining equipment. Henan Zhongxing Grain and Oil Machinery provides you with soybean oil refining equipment hydration and degumming operation steps, and soybean oil refining equipment manufacturers. When many customers and friends buy soybean oil refining equipment, they are worried that the operation is too difficult, and they will not operate after buying it. Henan Zhongxing grain and oil equipment manufacturer will introduce the operation steps of soybean oil refining equipment hydration and degumming. Friends who are worried about not operating can take a look.

The first step of degumming operation of soybean oil refining equipment is preheating: use a heater to preheat the deacidified oil to a hydration temperature of about 60°C.

The second step of soybean oil refining equipment degumming operation, add water: When adding water, note that the temperature of the hot water added should be 3~5°C higher than the oil temperature. The method of adding water can be spraying. The added water is thin and the water quality should be soft water. Adding water is the most important stage of hydration and degumming, and you need to pay attention to the amount of water, the temperature of the water and the temperature of the oil. The phospholipid content in the oil needs to be calculated before adding water. Generally, the amount of water added is 3.5 times the phospholipid content. Depending on the quality of the oil, the amount of water added can be increased accordingly.

Observe at any time during the process of adding water, so as to adjust the speed of adding water and the amount of water added in time. In the process of adding water, it is necessary to stir the fat and oil, and continue to stir after the addition of water, and the stirring time needs to last for more than half an hour. Once you find that the phospholipids begin to accumulate into colloidal particles, the stirring can be gradually slowed down. When there is an obvious oil path on the liquid level, the stirring should be stopped immediately.

The third step of soybean oil refining equipment degumming operation is to stand for precipitation: After the stirring is stopped, the hydration and degumming of the basic oil is more than half completed, and the rest is to stand and wait for the hydration and separation of the phospholipids. Generally, it takes 3 to 8 hours to stand still, but it needs to be determined in actual production. Generally speaking, a longer standing time is better. When the temperature is relatively low, indirect steam can be used to keep the oil temperature at about 70°C during the standing period to reduce the oil content in the phospholipid oil feet. The holding time should be more than four hours. After the oil has settled and settled, the yellow water is discharged from the bottom of the pot, and then the phospholipid oil feet are discharged, and the hydration and degumming is completed.

The main purpose of oil hydration degumming is to remove the phospholipids in the oil, and the oil refining equipment hydration degumming is to use the hydrophilicity of the phospholipids to achieve the purpose of separating the phospholipids from the oil. These are the operation steps of oil hydration and degumming introduced by Henan Zhongxing Grain and Oil Machinery. After reading it, you will find that the operation is actually very simple!

The soybean oil refining equipment produced by Henan Zhongxing Grain and Oil Machinery has advanced technology, simple operation, high quality and low price. It is your best choice for buying oil refining equipment!
