What are the current industrial vacuum drying equipment, advantages and disadvantages

Currently, the vacuum drying equipment commonly used in industry mainly includes the following:

Vacuum drying box: vacuum drying box is a common drying equipment, suitable for drying a variety of materials. It uses vacuum technology to create a low-pressure environment in a closed container, so that the moisture in the material is rapidly evaporated and taken away, so as to achieve the purpose of drying. The advantages of vacuum drying oven are fast drying speed, high efficiency, controllable temperature and humidity, suitable for drying a variety of materials. The disadvantage is that it needs manual operation, and is not suitable for large materials or materials that need to be dried in large quantities.

Vacuum dryer: vacuum dryer is a kind of equipment suitable for drying liquid materials. It uses vacuum technology to liquid materials in the water quickly evaporate and be taken away, so as to achieve the purpose of drying. The advantages of vacuum dryer are high drying efficiency, fast speed, continuous production, suitable for large-scale production. The disadvantage is that it needs professional operation and maintenance, and the price is higher.

Vacuum Freeze Dryer: Vacuum Freeze Dryer is a kind of drying equipment using the principle of ice crystal sublimation. It first freezes the material into a solid state, and then sublimates the moisture in the material directly into gas under the low temperature and low pressure environment, so as to achieve the purpose of drying. The advantages of vacuum freeze dryer are fast drying speed, high efficiency, can retain the nutrients and original form of the material, applicable to a variety of materials drying. The disadvantage is the need for low-temperature operation, equipment costs and maintenance costs are high.

Overall, all kinds of vacuum drying equipment have their unique advantages and disadvantages, suitable for different application scenarios. Choosing the right equipment is based on the characteristics of the material, production scale and requirements.
