Beer Keg Filling Machine Selection Guide
Choosing a beer keg filling machine is a capacity and quality decision: manual filling limits throughput and invites oxygen ingress, while the right semi-auto or rotary unit protects flavor and cuts labor. This guide compares the practical options.
Manual vs Semi-Automatic vs Rotary
Manual fillers suit under 10 kegs per day; semi-auto single-head units with purge control cover 20–40 kegs per shift; rotary multi-head lines serve regional distribution.
Purge and Counter-Pressure Control
Quality starts with CO2 pre-purge and counter-pressure fill. Verify the machine holds purge time and bowl pressure within spec batch to batch, not just at demo conditions.
Keg Washer Integration
Pair the filler with a keg washer sharing the same CIP supply. Turnaround time between fills depends on wash cycle length and automation level.
Change Parts and Keg Types
Quick-change spears adapt Euro, DIN and Cornelius kegs. Confirm change part availability and documented changeover time before ordering.
Frequently Asked Questions
What capacity needs a rotary keg filler?
Beyond roughly 60 kegs per shift, multi-head rotary units pay back through labor savings.
Can one machine fill different keg sizes?
Yes, with size-specific spears and change parts for 20L, 30L and 50L kegs.
Does the keg filler need CIP?
It ties into the shared brewery CIP loop for internal cleaning between product runs.
