Vacuum drying enables product-friendly and effective drying even at low temperatures.
The principle of Vacuum Drying
With vacuum drying, moisture is removed from a material by reducing the pressure in a vacuum chamber.
The drying process is based on the principle that volatile substances – such as water or organic compounds (solvents) – have a significantly lower boiling point under vacuum than at atmospheric pressure. This allows them to evaporate efficiently without putting any thermal impact on the material. Overheating is avoided because the material is dried evenly and gently.
During the process, all of the material is located in the vacuum chamber. The pressure is reduced until the vapour pressure of the water or volatile substances is reached. From this point onwards, the moisture begins to evaporate and is then removed via the vacuum pump with optional distillation or condensation.
Because the vacuum in the vacuum chamber reaches all areas of the material, drying is homogeneous and takes place in a short time. The heat energy required for this usually comes from the upstream process, if necessary, additional energy is supplied.
Meier Prozesstechnik offers everything from a standardized Meierdryer to specific vacuum dryers from a single source.
The Meierdryer is the basic model for challenging drying requirements in a wide range of applications and can be rented or tested in operation at any time.
Meier Vacuum Dryers
Vacuum Drying Systems
Due to the wide variety of drying requirements, our vacuum dryers are usually designed specifically to meet customer requirements. Thanks to the large number of vacuum dryers we have realized so far, we use standardized components and solutions. Recently, we also introduce our standardized Meierdryer.
Our vacuum dryers can also be easily integrated into existing production lines at a later date or operated as a stand-alone solution with their own PLC control system. Request information now!

Advantages of a Vacuum Dryer
Many materials are temperature-sensitive due to their special properties. Drying at high temperatures would impact the original properties of the material and is therefore unsuitable. Vacuum drying allows moisture and solvents to evaporate at low temperatures without damage the material. In addition, the evaporated substances can be recovered by means of distillation or condensation.
Vacuum drying offers some decisive advantages over other types of drying:
- Reduced energy/operating costs
- Short cycle/drying times
- Drying process that protects materials
- Drying independent of geometry
- Maximum level of drying and quality
- High purity
- Corrosion problems ruled out
- Low maintenance required
Application areas:
- Automotive and rail industry
- Electrical industry
- Research and development
- Glass and ceramics industry
- Aerospace
- Mechanical and systems engineering
- Medical technology
- Metal processing industry
- Surface industry
- Semiconductor industry
