How to link the refrigerant tube and vacuum box of the 'solved' vegetable vacuum pre cooler

　　Vegetable vacuum pre cooler is a device that reduces material temperature by extracting air from a vacuum environment. It mainly consists of vacuum system, refrigeration system, control system, etc. Among them, the refrigerant pipe is an important component of the vacuum precooler, which transfers the refrigerant from the refrigeration system to the vacuum box to achieve the purpose of cooling. So, how do refrigerant pipes and vacuum boxes connect? Below, we will explain in detail.

　　Install refrigerant pipe

　　Firstly, it is necessary to install the refrigerant pipe into the refrigeration system. Refrigerant pipes are usually made of copper pipes, with refrigerant circulating inside. When installing refrigerant pipes, the following points should be noted:

　　(1) The length of the refrigerant pipe should be moderate, not too long or too short. Excessive length can cause slow refrigerant circulation, affecting the cooling effect; If it is too short, it will cause the refrigerant to not circulate fully, which will also affect the cooling effect.

　　(2) The bending radius of refrigerant pipes should be as large as possible to reduce the flow resistance of refrigerant inside the pipes.

　　(3) The connection of refrigerant pipes should be made using copper pipe joints and sealed with airtight sealing materials to prevent refrigerant leakage.

　　Install vacuum box

　　Next, it is necessary to install the vacuum box onto the refrigerant pipe. Vacuum boxes are usually made of stainless steel and can hold materials that need to be cooled inside. When installing a vacuum box, the following points should be noted:

　　(1) The size of the vacuum box should match the size of the refrigerant pipe to ensure that the refrigerant pipe can pass through the vacuum box smoothly.

　　(2) The bottom of the vacuum box should be sealed at the connection with the refrigerant pipe to prevent air from entering the vacuum box.

　　(3) The door of the vacuum box should be equipped with sealing strips to ensure the sealing inside the vacuum box.

　　Connect the refrigerant pipe to the vacuum box

　　Finally, it is necessary to connect the refrigerant pipe to the vacuum box. When connecting, it is necessary to pass the refrigerant pipe through the bottom of the vacuum box and connect the other end of the refrigerant pipe to the refrigeration system. After the connection is completed, it is necessary to seal the connection between the refrigerant pipe and the vacuum box to prevent refrigerant leakage.

　　We have briefly introduced how to connect the refrigerant tube and vacuum box of the vegetable vacuum pre cooler, and it is important to note the method of connecting the refrigerant tube and vacuum box. During the installation process, attention should be paid to the length, bending radius, and sealing of the refrigerant pipe at the connection to ensure the quality of the connection between the refrigerant pipe and the vacuum box.
