Blend neutral-base alcohol, deaerated water (DAW), flavour, and sweetener with accuracy and control; powered by 4B Automation & 4B Systems.
- Batch make-up for hard seltzer often results in ABV drift, °Brix variability, pH swings, and oxygen pickup, causing inconsistent taste and label compliance risks.
- Frequent flavour changes and manual checks lead to longer changeovers, higher waste, and reduced line efficiency.
- Producers need a continuous, automated blending solution that maintains consistent product quality, flavour balance, and shelf stability; while minimising downtime and ingredient loss.
Our Solution:
- The 4B Automation & 4B Systems Inline Blender for Hard Seltzer provides continuous, recipe-driven blending of neutral-base alcohol and deaerated water (DAW) with inline measurement and control of ABV, °Brix, and pH.
- Using dual Coriolis mass-flow meters, an inline alcohol meter (density/ultrasonic with temperature compensation), and a refractometer for °Brix, the system automatically maintains key product parameters through closed-loop control.
- Optional DO and COâ‚‚ analyzers protect shelf life and sensory attributes, while a hygienic skid design allows for rapid flavour changeovers and easy maintenance.
- Fully automated and locally supported, it ensures dependable, repeatable blending for every batch of hard seltzer.
