Consistent, energy-efficient carbonation for hard seltzers; maintain flavour, clarity, and fizz with hygienic Alfa Laval technology.
In hard seltzer production, carbonation defines both mouthfeel and consumer satisfaction.
- Under-carbonation leaves the drink flat or dull.
- Over-carbonation risks foaming, off-flavours, and packaging stress.
Manual gas injection or basic dosing setups often lead to:
- Variable COâ‚‚ levels across batches.
- Gas waste and uneven dissolution.
- Bubble instability and haze formation.
- Oxygen pickup that impacts shelf life and taste.
Producers need a hygienic, automated COâ‚‚ dosing solution that ensures full gas dissolution, repeatability, and low operating cost; without compromising clarity, flavour, or carbonation retention.
Our Solution:
- 4B Automation & 4B Systems provides Hard Seltzer Carbonation / COâ‚‚ Dosing Units designed for high performance, reliability, and process consistency.
- Using Alfa Laval’s Carboset™ and Carboblend™ platforms, these systems inject CO₂ directly into the liquid stream using hygienic static mixers or controlled acceleration zones. The result is full gas absorption without diffusers, porous stones, or excessive turbulence; preserving flavour, clarity, and stability.
- Each system is skid-built, fully automated, and CIP-compatible, featuring inline COâ‚‚ analysers, back-pressure regulation, and real-time feedback control. With integrated PLC automation, recipe management, and remote diagnostics, these modules provide dependable carbonation performance for all hard seltzer lines.
