Bottle Filing and Capping Machine

Beer Bottling Machine

4 to 10-Head Configuration PLC Automatic Control Isobaric CO₂ Filling

Product Description:

The beer bottling machine from ZR BREW is a fully automatic bottle filling and capping system engineered for craft breweries, microbreweries, and commercial beer production facilities requiring consistent, high-throughput bottling performance with minimal beer loss. Using an isobaric filling method with CO₂ pressurisation and vacuumisation, the machine completes bottle filling and crown capping in a single continuous pass — delivering stable, precise fills with a built-in pressure compensator that maintains process integrity across each bottling run. Available in 4-head, 6-head, 8-head, and 10-head configurations to match your current production volume and allow for future capacity expansion.

Advantage of Configuration

Isobaric Filling Minimises Beer Loss and CO₂ Escape
The machine uses an equal-pressure (isobaric) filling method in which bottles are pre-pressurised with CO₂ to match the tank pressure before liquid enters. This dramatically reduces foaming, dissolved gas loss, and beer wastage during filling — maintaining carbonation levels and product quality batch after batch in high-throughput commercial bottling environments.

Integrated CO₂ Pressurisation, Vacuumisation, Filling, and Capping
All four stages of the bottling process — CO₂ flushing, vacuum creation, liquid filling, and crown cap sealing — are completed within a single machine pass. This integrated design reduces the number of handling steps, minimises oxygen exposure during filling, and simplifies the bottling line footprint compared to multi-machine sequential setups.

PLC Automatic Control with Fully Adjustable Parameters
Every key process parameter — filling speed, pressure setpoint, head sequence, and capping force — is managed by a programmable PLC controller with operator-adjustable settings. This allows breweries to fine-tune the filling process for different beer styles, carbonation levels, and bottle sizes without mechanical changes to the machine configuration.

Pressure Compensator Ensures Fill Consistency Across All Heads
A dedicated pressure compensator maintains equalised pressure across all filling heads throughout each production run, preventing variation in fill volume between individual bottles — critical for compliance with net content regulations in export markets and consumer quality expectations in commercial beer distribution.

Scalable Head Configuration for Current and Future Output
Available in 4, 6, 8, and 10-head configurations, the machine can be specified to match current production requirements while providing a clear upgrade path as bottling volume grows. Upgrading head count supports higher throughput without replacing the entire filling and capping system.

Factory-Direct Manufacturing with Global Export Support
Manufactured at ZR BREW’s 10,000㎡ production facility with full pre-delivery commissioning and inspection, the machine ships with English installation and operation documentation. Remote technical support and optional on-site commissioning assistance are available for international brewery installations.

Frequently Asked Questions

What types of brewery is this beer bottling machine suitable for?

The beer bottling machine is designed for craft breweries, microbreweries, commercial beer producers, and brewpubs that bottle their finished beer for retail sale, on-site distribution, or export. The 4-head configuration suits lower-volume craft operations, while the 10-head configuration is appropriate for higher-throughput commercial bottling runs. The machine handles both 330ml and 650ml standard beer bottle formats, with capacity for bottles up to 2L on compatible configurations.
Can the bottle filling and capping machine handle different bottle sizes?

Yes. The machine is designed to handle 330ml and 650ml standard beer bottle formats as standard configurations, and can accommodate bottles up to 2L. For non-standard bottle shapes or sizes, buyers should confirm compatibility with ZR BREW’s technical team at the quotation stage. All filling parameters and head settings are adjustable via the PLC controller to accommodate different bottle volumes and carbonation requirements.
How does the isobaric filling method protect beer quality during bottling?

Isobaric (equal-pressure) filling works by pre-pressurising each bottle with CO₂ to match the pressure of the beer in the supply tank before the liquid valve opens. This prevents a sudden pressure drop as beer enters the bottle, which is the primary cause of foaming and dissolved CO₂ loss during conventional gravity filling. The result is a calmer, more controlled fill that preserves carbonation levels, reduces oxidation exposure, and minimises product loss at the filling head.
Can the filling and capping process run automatically without constant operator supervision?

Yes. The machine operates under full PLC automatic control. Once filling parameters — including target fill volume, head pressure, filling speed, and capping sequence — have been set and confirmed by the operator, the machine manages each cycle automatically. The PLC interface allows operators to monitor the process in real time and adjust parameters as needed without stopping production. This level of automation is suited to commercial bottling environments where consistent unattended operation is required between operator checks.
What should buyers confirm before ordering the beer bottling machine?

Before placing an order, buyers should confirm the following: required production output in bottles per hour, primary bottle sizes and formats to be filled, local electrical supply specification, available floor space for machine installation, whether the machine will be integrated into an existing bottling line or installed as a standalone unit, and whether capping is required for crown caps only or also for other closure types. ZR BREW’s technical team will confirm machine configuration, head count recommendation, and any adaptation requirements based on the buyer’s specific bottling line layout and production targets.
