In industrial practice, vacuum usually describes an enclosed space in which the pressure is below atmospheric pressure. There are numerous vacuum applications, including:
- Packaging processes
- Pneumatic conveying
- Drying
- Pressing and laminating
- Workpiece handling
What these vacuum applications have in common is that a vacuum is generated inside a technical system. However, the exact purpose of the pressure ratios differs. For example, the vacuum is used to suck in objects during workpiece handling.
When packaging under vacuum, the focus is on protecting the goods from oxygen, moisture and dust.
