Cottonseed oil refining production line
1. Overview of Cottonseed Oil
Cottonseed oil is the oil extracted from cottonseeds. It is divided into pressed cottonseed oil, extracted cottonseed oil, genetically modified cottonseed oil, cottonseed crude oil, and finished cottonseed oil. The color is darker than other oils, and it can be eaten after refining. It contains a lot of essential fatty acids and should be mixed with animal fat. The content of linoleic acid in refined cottonseed oil is particularly high, which can effectively inhibit the rise of cholesterol in the blood and protect the human body. health. Especially suitable for fried food.
2. Cottonseed Oil Benefits
Refined cottonseed oil is generally orange-yellow or brown. The fatty acid contains palmitic acid 21.6-24.8%, stearic acid 1.9-2.4%, arachidic acid 0-0.1%, oleic acid 18.0-30.7%, linoleic acid 44.9-55.0%, The refined cottonseed oil has removed toxic substances such as gossypol and can be eaten by humans. Cotton clear oil contains a large amount of essential fatty acids, because the content of linoleic acid in cotton clear oil is particularly high, which can effectively inhibit the rise of cholesterol in the blood and maintain the health of the human body. The absorption rate of cotton clear oil by the human body is 98%.
3. Necessity of cottonseed oil refining.
Because the content of linoleic acid in cotton clear oil is particularly high, it can effectively inhibit the rise of cholesterol in the blood and maintain the health of the human body. However, eating crude cottonseed oil (crude oil) can cause damage to spermatogenic cells, resulting in infertility. The national health standard requires that the content of gossypol in oil is less than 0.02%. When gossypol in cotton oil is not higher than 0.02%, it has no effect on the human body. Therefore, cottonseed oil must be refined before it can be eaten. Since May 1, 2004, the national health and epidemic prevention and quality inspection departments have clearly stipulated that various unrefined edible oils are prohibited from being sold on the market.
4. Process flow of cottonseed oil refining production line
Cottonseed oil crude oil→degumming→deacidification→washing→decolorization→deodorization→winterization→finished first-grade cottonseed oil
5. Main equipment in the cottonseed oil refining production line
Neutralization pot: used for acid refining, alkali refining and water washing;
Decolorization pot: use bleaching oil and depigmentation;
Deodorizing pot: used to remove the smell of grease; (made of stainless steel)
Heat-conducting oil furnace: provide the heat energy required for production, and the temperature reaches 280°C;
Vacuum pump: provide the vacuum required for decolorization and deodorization, which can reach more than 755mmHg;
Air compressor: dry bleaching clay;
Filter press: filter clay;
Steam generator: to generate steam required for deodorization distillation.
6. Precautions for operation of refining equipment
(1) After each replacement of the heat transfer oil, the heat transfer oil furnace must be kept at 90°C for more than 5 hours.
(2) For neutralization pots and decolorization and deodorization equipment, the use of heat energy must be reasonably distributed and adjusted. When deodorizing, it is necessary to ensure that the deodorizing temperature is 240-260 ℃, and other equipment mainly depends on the valve to adjust the balance.
(3) After overhaul, graphite gaskets must be used for heat conduction pipeline gaskets, and high-temperature valves must be used for replacement valves.
(4) Before the heat transfer oil furnace is ignited, the heat transfer oil pump must be started first. After the heat transfer oil furnace ceases fire, the heat transfer oil pump must continue to run, and the heat transfer oil pump can only be turned off when the temperature of the heat transfer oil drops below 100°C.
(5) It is forbidden to ignite the furnace without heat transfer oil; it is forbidden to ignite the furnace when the heat transfer oil pump is not running.
