Vacuum drying ovenIt is a device used to dry items and can be dried in a low-pressure environment. It can dry out items by reducing the pressure of gases in the environment and allowing moisture to evaporate quickly from the item.
When drying powders, the vacuum drying oven can maintain the uniformity and efficiency of drying. Since powders are usually hygroscopic, they are more difficult to dry at room temperature. However, in a vacuum drying oven, humidity and temperature can be controlled in a low-pressure environment, allowing drying.
The operation method of drying powder in vacuum drying oven.
1.Adjust the temperature.
For different kinds of powder, its drying temperature is different. In general, it is recommended to set the temperature between 60°C and 120°C in a vacuum drying oven. If the temperature is too high, it may cause powder agglomeration or pyrolysis, affecting the quality of drying.
2.Adjust the drying time.
The drying time of the powder is also affected by the temperature. In general, the drying time should be determined according to the type and moisture content of the powder. Generally speaking, the longer the drying time, the better the drying effect. When dealing with particularly wet powders, it is necessary to increase the drying time to ensure that they are thoroughly dry.
3.Control stress.
In vacuum drying ovens, pressure control is very important. The low-pressure environment can be adjusted using the valve. By reducing the pressure, the evaporation of the water can be accelerated, so that the powder dries more evenly.
Drying powder is a very important process that plays a vital role in the manufacture of the product. By using a vacuum drying oven, an equally efficient and homogeneous option can be provided for more efficient powder drying. This article details the correct way to dry the powder in a vacuum drying oven to achieve a good drying effect.
