What Tests Can Be Conducted in a Vacuum Dryer?

The vacuum drying oven is specifically designed for drying heat-sensitive, easily decomposable, and oxidizable substances. It maintains a certain vacuum level within the working chamber during operation and can fill the interior with inert gases, allowing for rapid drying even of complex compositions. It utilizes an intelligent digital temperature controller for setting, displaying, and controlling the temperature. The vacuum drying oven is widely applicable across various fields such as biochemical, chemical pharmaceutical, and food technology. So, what tests can the vacuum drying oven perform?

Here are several items listed by the editor:

1. Food Industry

During food drying tests, high-sugar food ingredients react with air during the drying process, becoming sticky or even charred, which is a burning phenomenon. Under the conditions of vacuum drying technology, these issues are easily controlled.

2. Recyclable Resources Industry

The recycling industry for materials containing alcohol, ethanol, and the like poses a significant risk when using conventional dryers, as these substances are flammable gases. Contact with dry air can easily lead to explosions or fires, which is also detrimental to recycling efforts. However, in a vacuum state, ethanol and alcohol are less likely to come into contact with air, thereby reducing the risk of explosions. Additionally, vacuum equipment is highly sealed, which can be utilized to facilitate recycling.

3. Metal Products Industry

The general test required in the metal products industry is high-temperature drying. While a standard drying oven may dry the test samples, it cannot prevent oxidation caused by high temperatures and air oxidation. However, a vacuum drying oven, with its vacuum pump removing air, will not be oxidized at any temperature.
