  • Product Details

In this topic, we can discuss the vacuum drying ovens used in the Industry. A vacuum drying oven is most commonly used for delicate drying processes, such as drying tiny parts or removing flammable solvents. The low-pressure environment also minimizes oxidation during drying. Vacuum drying oven can operate at temperatures as high as 200C to 250C.

How can use Vacuum Drying Ovens?

Vacuum drying oven commonly used to process cannabis extracts like BHO Residual solvents like Butane are evaporated in the vacuum chamber and are then pulled out of the chamber by the vacuum. This leaves behind a purified oil extract and greatly reduces the risk of fire when using solvents like Butane. This allows for extracts to be processed faster, and more importantly, safer. It is producing cannabis oil extracts the old-fashioned way with the massive fire hazard is hard to sustain and even harder to scale. Although vacuum ovens allow for BHO to faster and safer, they do have some nuances and take some require some precision to be set up optimally. Some common pitfalls when choosing and setting up vacuum drying ovens are choosing the wrong model for the desired application, setting up the product inside the oven for optimal heat exposure, and adjusting the settings too high to the point where a large amount of power and time are wasted. The cost of the vacuum oven itself and the high amounts of power consumption can make the startup cost high, so it’s very important to get your setup right the first time around.


As we know the standard atmospheric pressure is 101kpa, vacuum drying oven is a oven that will dry the material by pressure from -90kpa to -101kpa, normally in this vacuum condition the water will evaporate by lower temperature from 20 to 40 degree centigrade. Because of the lower temperature treated and no oxygen for chemical change, the material will be original color and no content lost after dried. So vacuum dryer is very good for some specific material or high request material.

But traditional vacuum drying oven have a common problem, the total drying time is too long and waste a lot of energy. Now a new technology was developed to reduce much drying time, it is vacuum microwave drying oven. Our vacuum drying oven use this technology, it is a good alternative vacuum drying oven now.
