Driers should be familiar to everyone, as they are an important equipment with a wide range of applications. There are many types of dryers, and the dryers used in different industries also vary. Today, I will talk to you about the relevant topics of refrigerated compressed air dryers. There are many specific usage methods for refrigerated compressed air dryers. Below, we will provide a detailed operation guide and operating mechanism introduction for the frozen compressed air dryer.

[Specific usage method of frozen compressed air dryer]

Many people are not very clear about the use of refrigerated compressed air dryers. Below are a few precautions I have compiled for everyone:

1. When removing the processed item, if it is a flammable item, it must be cooled to below the combustion point before air can be placed to avoid oxidation reaction and combustion.

2. When the vacuum box of the vacuum dryer does not require continuous pumping, the vacuum valve should be closed first, and then the power supply of the vacuum pump motor should be turned off, otherwise the vacuum pump oil will be poured back into the box.

3. If the drying time is long and the vacuum degree decreases, it is necessary to extract air again to restore the vacuum degree. The vacuum pump motor switch should be turned on first, and then the vacuum valve should be opened.

4. Do not dry explosive materials.

5. After releasing the vacuum, it is difficult to immediately open the box door due to the deformation of the sealing ring and glass door suction. It takes about 30 minutes to easily open the box door.

These are the key points to pay attention to before and after using a vacuum dryer! As long as everyone masters the above methods during use, there will be no malfunctions caused by improper use.

[Working principle of evaporator in frozen compressed air dryer]

The refrigeration dryer can achieve freeze-type operation, which cannot be separated from its four major components: refrigeration compressor, condenser, evaporator, and expansion valve. The most important component among them is the evaporator, and many people are not familiar with the working principle of the evaporator. Today, I will briefly introduce the working principle of the evaporator for everyone.

The content is as follows: Through the operation of the evaporator, compressed air is forced to cool, causing most of the compressed air to cool and form liquid water that is discharged from the refrigerated dryer, thereby achieving a dry compressed air. The working principle of an evaporator is to allow convective heat and mass exchange between air and low-pressure refrigerant vapor. When the low-pressure refrigerant liquid passes through the throttling device, it will form low-pressure refrigerant vapor in a disguised form in the evaporator, thereby absorbing surrounding heat and achieving the purpose of compressing air for cooling.

The above is a brief introduction to the evaporator, hoping to strengthen your understanding of the refrigerated dryer through the above content.

The above introduction about the specific usage methods of the frozen compressed air dryer and the working principle of the evaporator in the frozen compressed air dryer is hoped to help you understand the detailed operation guide and operating mechanism of the frozen compressed air dryer.
