Description

technical field [0001] The invention relates to the technical field of vacuum freezing, in particular to a high-efficiency freezing vacuum system for fatty acid processing. Background technique [0002] Vacuum cooling is based on the fact that vapor water molecules have higher energy than liquid water molecules, so water must absorb the latent heat of vaporization when vaporizing, and its latent heat of vaporization increases with the decrease of the boiling point. The material is placed in a closed vacuum box that can withstand a certain negative pressure and is evacuated by a suitable vacuum system. Only by absorbing heat from the object to be treated, the object to be treated can be rapidly cooled. [0003] In traditional fatty acid processing and production, steam jet refrigeration is mostly used, and the gas in the reaction kettle is evacuated by the high-speed flow of steam, so that a vacuum state is formed in the reaction kettle, and then the boiling point in the rea...

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-efficiency freezing vacuum system for fatty acid processing, to solve the problem in the above-mentioned background technology that most of the traditional fatty acid processing and production adopt steam injection refrigeration, and the gas in the reactor is pumped by the high-speed flow of steam. separation, so that a vacuum state is formed in the reactor, and then the boiling point in the reactor is lowered, and the water in the reactor is boiled and evaporated, so as to absorb a large amount of heat, and then achieve the effect of rapid cooling, but in the process of use, due to A large amount of steam is continuously generated in the reactor, so that the power steam needs to carry a large amount of steam generated by the reactor to move at a high speed, and then the power steam will distribute a large amount of kinetic energy to the steam generated by the reactor during the cooling movement, so that the equipment can meet the requirements of the power steam. The flow rate can reach the level of vacuum, and the average flow rate of the entire steam power system can only be maintained by increasing the output of power steam. This makes the traditional fatty acid processing process consume a lot of steam and consume energy. high volume problem
