Why does the vacuum oven not set the temperature uniformity parameter?

The application of vacuum oven is used in the fields of biochemistry, chemical pharmacy, medical and health, agricultural research, environmental protection and so on, for powder drying, baking and cleaning and cleaning of all kinds of glass containers. It is especially suitable for rapid drying of heat sensitive, easily decomposed, easily oxidized and complex components.

Climatest Symor is specialized in heat treatment equipment, baking process equipment, environmental and reliability test equipment and storage equipment, By a group of years engaged in thermal, vacuum, Structure, semiconductor and other industries as the core of professional engineers and technicians, Climatest Symor  is an comprehensive enterprise that integrates design, manufacturing, sales with after-sales service capabilities.

The following is a solution to why the vacuum oven does not set temperature uniformity.
Electric heating (blast) ovens are equipped with temperature uniformity parameters: natural convection oven for the upper limit of the working temperature multiplied by 3%, The forced convection oven multiplies 2.5% for the upper limit of the working temperature. But the electrothermal vacuum oven has no temperature uniformity, This is because the vacuum oven depends on the movement of gas molecules inside to make the studio temperature uniform almost impossible. Therefore, Conceptually, we can no longer use the definition of temperature uniformity specified in the electric heating oven to the vacuum oven.

It is also meaningless to set this indicator under the vacuum state. The amount of thermal radiation is inversely proportional to the square of the distance. Same object, The radiation heat received 20 cm from the heating wall is only 1/4 of the 10 cm from the heating wall. Very different. This phenomenon with the winter sun, The sun‘s warm, The cold side of the sun is one reason. Because the vacuum oven is difficult to make the radiation heat of each point in the three-dimensional space of the studio uniform, And the lack of authoritative assessment methods, This becomes the vacuum oven standard without temperature uniformity parameters.
