Peony seed oil physical refining complete equipment

Physical oil refining is our company’s specialty. We have developed many proprietary and patented technologies. We have very rich practical experience in oil refining equipment. We also apply the technology of processing rice bran oil, cottonseed oil, animal oil and other difficult-to-process special oils. On oil, good results have been achieved.

The peony seed oil refining of QIE Grain and Oil Machinery Company adopts physical refining technology. According to the output size, it can choose semi-continuous and full-continuous forms. The whole set of equipment including pipeline valves are made of stainless steel.

Deacidification and deodorization is a distillation physical process, equipped with a patented product combination deacidification and deodorization tower developed by our company. This tower has the functions of physical deacidification and benzoic removal, which can reduce the consumption of refined caustic soda and activated carbon. It effectively guarantees the peroxide value and avoids the color and acid reversion of oil under high temperature. After the development of the tower by QIE Grain and Oil Machinery Co., Ltd., it has set off a trend of upgrading and upgrading of deacidification and deodorization equipment in the industry.

The refined oil produced by our company’s peony oil refining equipment can meet the national first-class oil standard. Key indicators such as color, acid value, benzo ratio, peroxide value, trans fatty acid, etc. can meet national standards, with low loss and low production cost. Good economic benefits!


Peony seed oil degumming: The colloidal impurities in crude oil are mainly phosphorus. The presence of gelatinous substances such as phospholipids not only reduces the quality of oil, but also promotes transitional emulsification between oil and lye during the alkali refining and deacidification process, which increases the difficulty of separation of saponins and aggravates the loss of neutral oil. Therefore, it should be removed first. For hydration and degumming, the temperature is raised to 60°C under stirring, and boiling water of 4 to 5 times the phosphorus content in the oil is added. The water temperature is slightly higher than the oil temperature. When necessary, 0.2%—0.3% of the oil weight in the water can improve the hydration effect. Adding water is an important stage of hydration. The amount of water added, the temperature of water and oil, the speed of stirring and adding water, etc. should be carefully controlled. During hydration, you should always use a spoon to sample and observe in the pot, and flexibly control the amount of water and the speed of water addition according to the situation. After the water is added, when the rubber particles begin to gather, start slow stirring and heat up to 75°C. When the liquid level shows obvious oil path, stop stirring and let it stand for 3-4 hours, and 4-5 hours in winter. Until the hydration oil feet are separated from the grease qualified, the oil feet are released, and the degumming oil enters the next process. The peony seed oil contains low phospholipids, so there is no need to separate degumming in the production, and it can be carried out together with the deacidification process.

Deacidification of peony seed oil: Deacidification of oil is mainly to remove free fatty acids in crude oil, as well as a small amount of colloids, pigments and trace metals in the oil. Deacidification operation is one of the important factors that directly affect the yield and quality of oil refining. Alkali refining and deacidification is widely used in industrial production. Pump the cleaning oil into the pot and stir evenly to raise the oil temperature to 60°C. At the same time, perform rapid stirring at a speed of 60 rpm, spray the measured lye into the oil evenly, and continue to stir quickly to make it fully mixed with the oil. Then change to slow stirring at 30 rpm. At the same time, raise the temperature to 75°C until the oil and soap particles are clearly separated and easy to precipitate, stop the gas, let the soap particles settle, let it stand for 3 hours, and then wash with hot water slightly higher than the oil temperature to remove Eliminate impurities such as soap particles remaining in the oil. When the oil temperature drops to 60°C, start filtering and enter the next program.

Peony seed oil decolorization: The color and luster of the oil and some other impurities must be decolorized to reach the product quality standard. At the same time, it provides more favorable conditions for deodorization and refining. Decolorization must meet the final product color and luster index; remove relevant pigments and quantitative metals; further remove traces of saponins, phospholipids and other colloidal impurities and certain odor substances remaining in the oil; remove polycyclic aromatic hydrocarbons and residual pesticides; reduce oil quality Oxidation value. Activated clay is used as a decolorizing agent, and an appropriate amount of activated carbon can be added when necessary. The decolorized grease is sucked into the decolorizing pot from the oil storage tank by means of vacuum, and heated to 90°C under vacuum, and the air and moisture in the oil are then removed. Then suck in the liquid decolorizing adsorbent (the amount is based on the color standard achieved by the decolorization, generally between 1-5% of the oil weight), and under the condition of full vacuum stirring (the vacuum is an absolute pressure of 8 kPa), the contact between the oil and the agent is about After 30 minutes, it was cooled to 70°C and pumped into the filter to remove the decolorizing agent to obtain a decolorizing oil.

Peony seed oil deodorization: The purpose of oil deodorization is to remove odor-causing substances in the oil and other substances that are easy to volatilize, improve the smell and color of the oil, and increase the stability of the oil. The peculiar smell of oil, the peculiar smell produced during decolorization, the clam smell produced by the oxidation of oil, etc. In the deodorization stage, these unpleasant odors are required to be sprayed directly into the steam distillation at high vacuum and high temperature to remove them. First, open the steam valve and cooling water valve of the solar jet vacuum pump to vacuum the deodorization pot. When the vacuum reaches a certain level, open the oil inlet valve to suck the decolorized oil into the deodorization pot by vacuum, and then open the thermal oil valve to reduce the temperature in the pot. When the temperature rises to 190°C and the temperature reaches 100°C, the direct steam is turned on to fully turn the oil in the pot. Spray direct steam for about 3 hours. During the entire deodorization process, the vacuum must maintain a residual pressure of 0.13-0.8 kPa, and the direct injection volume is about 5%-15% of the processed oil weight. 30 minutes before the deodorization time arrives, turn off the heat transfer oil heating system. After the oil deodorization is completed, turn off the direct steam, open the cooling door, and cool the oil below 70°C, then turn off the vacuum pump, break the vacuum, and pump out the deodorized oil.
