Reasons and solutions for non cooling of fruit and vegetable freeze-drying machine

　　I believe everyone may encounter the reason why the fruit and vegetable freeze dryer does not cool. Based on the knowledge base of engineers from Dachang, Ganzhou, we will also explain some specific reasons that may cause the fruit and vegetable freeze dryer to not cool and corresponding solutions:

　　Refrigerant leakage

　　If the refrigerant leaks, it will cause the machine to be unable to effectively cool. At this point, it is necessary to first identify the location of the leak and repair it before adding an appropriate amount of refrigerant.

　　Condenser overheating

　　If the condenser overheats, it may also cause the machine to be unable to effectively cool. At this point, the condenser should be checked for dust or other debris blockage and cleaned to ensure smooth air circulation.

　　Compressor failure

　　If the compressor malfunctions, it may also affect the cooling capacity of the machine. At this point, it is necessary to have professional personnel inspect and repair the compressor, and if necessary, a new compressor may need to be replaced.

　　There is a problem with the expansion valve

　　If the expansion valve cannot work properly, it may also lead to poor cooling effect. At this time, the working status of the expansion valve should be checked and appropriate adjustments or replacements should be made.

　　We have briefly introduced the reasons and treatment methods for the non cooling of fruit and vegetable freeze-drying machines here. It should be noted that the above treatment methods are only for general reference and suggestions. In the actual operation process, it is best to seek the help of professionals when encountering problems to avoid unnecessary safety accidents.
