Working principle
From liquid stream to controlled gas release
The useful mechanism is a sequence, not a single vacuum reading.
- 01
Present more liquid surface
A distributor creates a film, spray, swirl or other controlled flow pattern. The right method depends on product behaviour.
- 02
Lower gas partial pressure
The vacuum system reduces pressure above the liquid, encouraging free and dissolved gases to leave the product.
- 03
Separate gas and vapour
Released gas leaves through the vacuum path. Condensation may be evaluated when water or aroma vapours matter.
- 04
Control liquid level and discharge
The product pump removes liquid while the vessel remains under vacuum and the downstream process stays stable.
- 05
Protect the downstream path
Closed transfer, sound pump suction and suitable buffers help avoid reintroducing air before the critical step.
Performance variables
Why one vacuum number cannot define the result
Gas release changes with the liquid and the process condition. The specification must connect these variables to an agreed measurement.
Limits & trade-offs
What a responsible specification says out loud
Deaeration does not replace a validated microbial-control step.
Foam, evaporation, aroma loss and pump stability may define the operating window.
Re-aeration can occur before heating, storage or filling.
Unknown, viscous or aroma-sensitive products may require testing.
