In the stage of fatty acid distillation, vacuum unit must be evacuated by vacuum unit to reduce the boiling point of the material and then heat and evaporate and then cool back to achieve the ideal effect. How to select the correct vacuum unit in the process of fatty acid distillation recovery is a great concern.
With the improvement of the people’s living standard, the consumption of edible oil has been increased year by year, resulting in a large amount of waste oil and fats and fats. Many new technologies and methods have been developed for the treatment and application of these waste oils and waste materials. In China, a whole industrial chain of collection, production and application has been formed.
The source of waste oil:
1. Discarded oils and fats from restaurants and canteens.
2. slaughtering enterprises’ leftovers.
3. leather processing industry. Sources of oily leftovers: mainly from the leftovers produced by edible oil processing enterprises, such as cottonseed oil, soybean oil, rapeseed oil, peanut oil and other sludge and soap horn.
Processing methods and development prospects:
No matter what kind of industry these waste oils and fats are applied to, they must first be purified and made into crude fatty acids. Then different processing methods are used for different oils to obtain different quality fatty acids, which are used in soap making, paint, fatty acid deep processing and so on. Crude fatty acids, which are widely used in soap making industry, are widely used. Fatty acids used in the production of soap can be further fractionated into other acids through acidification, hydrolysis and distillation.
The production of fatty acids at the same time produces plant bitumen, which can be applied to casting adhesives instead of heavy oil as fuel oil. In the course of the whole process, distillation is also good for the selection of vacuum pump, only to achieve a certain vacuum required heating material to make the best effect of the vacuum pump, the most energy-saving, the vacuum unit can help you solve these problems, vacuum units in vacuum process can reach a certain degree of vacuum after reducing oil. The boiling point of the fat can be distilled or fractionated at low temperature.
