What Problems Does Ultrasonic Defoaming System Solve?
Date:Sep 05, 2019
The operating principle of the foam control system is that it breaks foam that is in the head space, or above the neck of the can and bottle. It uses state of the art technology in high powered ultrasonics to resonate the air between the sonotrode and the foaming product. This resonance collapses the foam, allowing it to be returned into the can or bottle.
With the application of the Cavitus system, product losses due to over foaming are reduced, sometimes eliminated. These savings can make a significant impact on the plant revenue. With product losses reduced, filler volume set points (electronic for volumetric, longer vent tubes for mechanical fillers) can be reduced. Reducing setpoints further reduces product losses due to the increase in head space volume.
Bottling and canning lines are often run at slow speeds to reduce the degree of foam creation during filling, and across the transition area before capping and seaming. A key indicator of this problem is if a production line is running at less than its original design capacity (OEM rating). By eliminating the excess foam created in the filling process using ultrasound, Cavitus can deliver an increased line speed/production of 10% or more.
Foam generation increases with product temperature due to the shift in carbonation saturation levels. Many plants reduce filling temperatures close to zero Celsius in order to minimise foaming. With the application of the Foam Control system significant savings in chilling and rewarming utilities can be made which further reduce the plants carbon footprint.
