Vacuum precooling machine for water spinach is a machine equipment used for precooling treatment of water spinach. Its working principle is to place the water spinach into a vacuum chamber, reduce the air pressure inside the vacuum chamber, so that the heat in the water spinach can be quickly dissipated, thereby achieving the purpose of pre cooling. The main components of the precooler include vacuum pump, cooling water system, control system, etc. Among them, the vacuum pump is used to reduce the air pressure inside the vacuum chamber, the cooling water system is used to provide cooling water, and the control system is used to control the operation of the machine and monitor parameters. The use of vacuum pre cooling machine for water spinach can effectively improve the pre cooling efficiency and quality, extend the shelf life of water spinach, reduce losses, and improve economic benefits. Meanwhile, the pre cooling machine is easy to operate and maintain, with high reliability and safety. The vacuum precooling machine for water spinach is an efficient and reliable precooling device that can be widely used for precooling treatment of vegetables such as water spinach, improving the quality and shelf life of vegetables.
Working Principle
The principle of the vacuum precooling machine for water spinach is to use the heat transfer effect of gas in a vacuum state to rapidly cool the vegetables and achieve the purpose of precooling. The specific principle is as follows:
1. After the vegetables are placed in the vacuum pre cooler, the machine starts the vacuum pump to reduce the air pressure inside the machine, so that the air around the vegetables is expelled.
2. In a low-pressure environment, the water in vegetables evaporates rapidly, absorbing the surrounding heat and causing the temperature of the vegetables to drop.
3. At the same time, the cooling water inside the pre cooling machine will flow through the cooling water circuit, taking away heat and maintaining a stable temperature inside the machine.
4. After a period of pre cooling treatment, the temperature of vegetables will drop to the appropriate refrigeration temperature, and the next step of refrigeration or freezing treatment can be carried out.
In short, the vacuum pre cooling machine for water spinach utilizes the gas heat transfer effect under vacuum to rapidly cool the vegetables, achieving the purpose of pre cooling and effectively extending the shelf life of vegetables.
