Automatic 500ML 1L 2L 3L PET Bottle Craft Beer Washing Filling Capping Bottling Machine Line

Q1  Is your beer filling machine designed for filtered beer, unfiltered craft beer, or both?

Our beer filling machine is compatible with both filtered standard beer and unfiltered craft beer

Q2  What is the maximum dissolved oxygen (DO) pickup per fill cycle on your beer filling machine?

Based on industry standards for modern counter-pressure filling machines, the maximum dissolved oxygen (DO) pickup is typically < 50ppb (parts per billion) , with high-performance systems achieving as low as 20–40ppb

Q3  What closures does the machine support — crown cap, screw cap, or swing-top?

Our glass bottle beer filling capping machine support crown cap,swing-top cap. And PET bottle filling capping machine support screw cap.

Q4  Can the machine handle both glass bottles and PET bottles for beer?

Glass bottle and PET bottle beer normally use separate filling machine due to different bottle feeding method, different cap types etc.

Q5  What is the smallest capacity beer filling machine you offer — is there a model suitable for a 500 BPH craft brewery?

The smallest capacity models we make is 300-500BPH for craft brewery. That is 6-6-1 washing filling capping 3 in 1 machine. With 6 washing heads, 6 filling heads and 1 capping head.

Q6  How does the machine handle pre-evacuation (CO2 purging) before filling to minimize oxygen contact?

Beer filling machine uses CO₂ purging to displace oxygen before filling: it first evacuates the chamber to reduce residual air, then injects CO₂ to flush out remaining oxygen, ensuring low O₂ levels prior to filling.

Q7  Does the machine include a built-in bottle rinser before filling?

Yes, beer filling capping machine can includes a built-in bottle rinser prior to filling. Also it can connect with a bottle rinser before it.

Q8  What is the level fill accuracy for beer — how do you measure and control the fill height?

The level fill accuracy for beer is typically ±1–2 mm (or ±2–4mL per 330–500mL bottle/can), ensuring consistent volume and legal compliance.

How to measure fill height:

- Inline check weighers** (most common) – weigh each container to calculate liquid volume.

- Gamma or X-ray fill level sensors – non-contact, measure through metal or opaque packaging.

-Vision systems / cameras – check meniscus position against a reference.

-Manual dipstick or glass scale– used for lab sampling or line setup.

How to control fill height:

- Electronic volumetric fillers – preset volume via flow meters or piston meters.

- Level control probes – mechanical or capacitive sensors inside the fill tube.

- Pressure or time-based filling valves – adjusted via PLC feedback from checkweighers or sensors.

Key control goal: maintain constant temperature, back pressure, and foam level** (fob) to avoid under/overfill.

Q9  Is the machine compatible with German-standard DIN 6650 filling valves or similar international standards?

Our beer filling valve use similar international standards which can meet with beer filling requirements.

Q10  What training and technical support do you provide after installation of the beer filling machine?

After installation, we provide:

1. Operator training(machine startup, filling adjustment, cleaning procedures).

2. Maintenance guidance (lubrication, wearing parts replacement, troubleshooting).

3. 24/7 technical support(online video call, remote diagnosis, or on-site service if needed).

4. Manuals & spare parts lists(PDF and hard copy).

This ensures minimal downtime and smooth beer filling production.
