The vacuum oven of industrial oven is a kind of oven which changes the boiling point of water and accelerates drying in vacuum state. It is different from the traditional oven.
The main difference lies in the word vacuum. In vacuum environment, there are many functions that the general environment can not reach, which is the real reason for many vacuum ovens.
Metal powder or metal products require high temperature drying. Although they can be dried by general drying skills, they can not hinder the oxidation reaction with oxygen attack in the air due to high temperature. The vacuum oven is pumped by the vacuum pump. No matter how high the temperature will not be oxidized.
When the food is dried, the food material rich in sugar is affected by the touch with the air in the drying process, which becomes sticky, and can be controlled well under the skill condition of vacuum drying.
Vacuum oven is suitable for baking articles, substrate stress removal, ink curing, film drying and so on.
Advantages of vacuum oven:
1. Heat circulation in the vacuum oven.
Vacuum oven electrical control is safe, accurate and reliable, complete function, simple operation, convenient repair and adjustment, low noise, high reliability, low cost, low energy consumption and high production efficiency.
The vacuum oven has strong durability, because the electric heater is sealed in the box, and the contact surface with the outside air is small, so it is not easy to be oxidized and corroded.
Since both are thermostatic devices, why not be universal. First of all, their temperature control range is different, blast dryer temperature is relatively high, the highest temperature can reach 400 degrees, or even 500 degrees, electrothermal incubator is normally below 80 degrees. But in this way, the blast dryer can replace the constant temperature incubator ah, because the temperature range of the incubator is in the blast dryer, why not use it? Because the temperature of blast dryer is relatively high, so his power is relatively large, low temperature is very controlled, and the use of electrothermal incubator is generally about 36 degrees, so it can not be replaced.
