Comparison of vacuum drying oven, blast drying oven and dry heat sterilization box
The box with high temperature effect has a sterilization box and an oven. Many people think that the two are the same products, so the three boxes are mixed and used, but these kinds of boxes are different. Ovens are sometimes referred to as drying ovens. They are generally divided into vacuum drying ovens and blast drying ovens. The oven we often refer to is a blast drying oven, which has a high temperature because it is only a tool for drying products at high temperatures. Therefore, the temperature is very high, but the high temperature is easy to damage the asbestos net in the box, and it is easy to dye the bacteria. Although the high temperature can kill the bacteria, the safety is still insufficient, so the user who wants to use the oven sterilization is still careful. In order to avoid the asbestos net dyeing bacteria with temperature controller, the sterilization box strictly controls the temperature to avoid repeated bacterial growth in the box and achieve the effect of high temperature sterilization. The specific differences are as follows:
Â
Vacuum drying oven
Blast drying oven
Dry heat sterilization box
Principle of sterilization
Designed for drying heat-sensitive, easily decomposable and easily oxidizable materials, it can be filled with inert gas inside, and it can be quickly dried for some complex materials.
Through the resistance heating, the temperature inside the box is increased and the air is blown, so that the water is quickly evaporated, thereby achieving the purpose of drying.
High-temperature dry heat oxidizes microorganisms, denatures proteins, and causes concentration of dielectrics to cause poisoning. Among them, the destruction of the cell protoplasm is mainly caused by oxidation, and the microorganism is killed, so that all microorganisms can be killed within a certain heating time.

Application field
Biochemistry, chemical pharmacy, medical and health, agricultural research, environmental protection and other research applications, for powder drying, baking and disinfection and sterilization of various glass containers
Widely used in welding rod industry, dip coating industry, printing industry, optical industry, motor industry, pharmaceutical industry
Dry heat sterilization is mainly used in various fields such as laboratory, medical, pharmaceutical, food processing and so on.

Temperature setting reason
With vacuum function, it can achieve the purpose of drying at relatively low temperature
High temperature drying
There is a temperature control system, the high temperature asbestos net is easy to be dyed, so the temperature of the dry heat sterilization box should not be too high.
