How vacuum drying ovens work?
A vacuum drying oven is most often used for delicate drying processes, such as drying tiny parts or removing flammable solvents. The low pressure environment also minimizes oxidation during drying. A standard vacuum oven can operate at temperatures as high as 200C to 250C.
How a Vacuum Belt Dryer Works?
A VBD is a continuous and automated in-feed (liquid & paste) and discharge drying equipment that uses a vacuum to control the drying process. Using a high vacuum, the raw materials’ boiling point (temperatures) reduces, and the moisture sublimes to gas directly.
How to choose ？
Vacuum low temperature continuous dryer is a new type of drying equipment, and vacuum drying oven is a traditional drying device. What they have in common is that they can both handle heat sensitive materials. The difference is that the vacuum drying oven is designed for drying special materials, while the vacuum low-temperature continuous dryer can adjust drying temperature, so it is more widely used.
Output and energy consumption comparison.
Comparison between 1 sets of vacuum belt dryer and 6 sets of square vacuum drying ovens.
Conclusion:
The output capacity of vacuum belt dryer(1 sets) is twice that of vacuum drying oven (six sets) in the same working time.
The consumption of steam and electricity is lower than that of vacuum drying oven.
Therefore, when purchasing vacuum drying equipment, users can choose vacuum low-temperature continuous dryer if they want high output and low energy consumption and to ensure that the nutrients of materials are not damaged.
