Applications in the General Beverage Industry (e.g., Mineral Water, Carbonated Drinks, Juices, Tea Drinks)

Although these beverages typically contain no alcohol, gas detection is still vital due to the use of CO₂ (carbonation), nitrogen (N₂, for inerting/packaging), refrigerants, and cleaning agents.

1. Carbonated Beverage Production

● Main Gas: Carbon Dioxide (CO₂)

● Risks:

1) CO₂used for carbonation is stored under pressure and can leak, leading to asphyxiation hazards.

● Gas Detection Applications:

1) Install high-precision CO₂detectors in CO₂ storage areas, carbonators, and pipelines.

2) Set up audible/visual alarms and automatic shutoff valvesfor rapid response.

2. Nitrogen (N₂) Use

● Purpose: Used for inert gas flushingin packaging (e.g., beer, juices, bottled water) to extend shelf life and prevent oxidation.

● Risks: Nitrogen is odorless and colorless; leaks can reduce oxygen levels, leading to asphyxiation.

● Gas Detection Applications:

1) Use oxygen monitorsto ensure ambient O₂ levels stay above 5% (safe threshold).

2) Install nitrogen leak detectorsin filling and modified atmosphere packaging (MAP) zones.

3. Cleaning & Disinfection Gases

● Common Gases: Ozone (O₃), hydrogen peroxide vapor, chlorine (in some cases)

● Risks: These gases are toxic or corrosiveat high concentrations.

● Gas Detection Applications:

1) Use ozone detectors, VOC detectors, or toxic gas sensorsto confirm safe residual levels post-disinfection.

2) Ensure proper ventilationand gas testing before re-entry.

4. Refrigeration Systems

● Risks: Refrigerants such as ammonia (NH₃)or fluorocarbons used in coolers or cold storage.

● Risks: These gases may be toxic, flammable, or environmentally hazardousif leaked.

● Gas Detection Applications:

1) Install ammonia detectors, fluorocarbon sensorsin refrigeration rooms and cold storage.

2) Systems should trigger alarms and automated ventilationupon detection.
