Gas Flushing Unit / Vacuum Pump for Beverage Deoxygenation

Product Specifications

Technical details and manufacturing context for Gas Flushing Unit / Vacuum Pump

Definition

The Gas Flushing Unit / Vacuum Pump is a critical component within the Automated Beverage Container Deoxygenation System. It performs a two-stage process: first, the vacuum pump evacuates atmospheric air (including oxygen) from sealed beverage containers; second, the gas flushing unit introduces an inert gas (typically nitrogen or carbon dioxide) to fill the void, creating a modified atmosphere that inhibits microbial growth and oxidative degradation, thereby preserving beverage quality and freshness. This unit is designed for integration into beverage manufacturing lines, where it operates in conjunction with container sealing and filling equipment. The unit is constructed from materials such as 316L stainless steel, food-grade elastomers, and aluminum alloy, ensuring compatibility with food contact and corrosive environments. Key parameters include an ultimate vacuum of 0.5–1.0 mbar, gas flow rate of 10–50 L/min, power consumption of 1.5–5.5 kW, cycle time of 2–8 seconds, operating pressure of 1.0–1.6 MPa, gas purity of 99.5–99.999%, residual oxygen level of 0.5–2.0%, operating temperature of 5–40°C, relative humidity ≤85%, ingress protection IP54–IP65 (per IEC 60529), material grade 304/316L (per ASTM A240), and weight of 150–350 kg. These values are reference ranges and must be confirmed for the specific model and application. The unit is not a standalone product but a component that requires proper integration and validation. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The unit operates through sequential vacuum creation and gas injection. A rotary vane or diaphragm vacuum pump reduces internal pressure to remove oxygen-laden air, achieving an ultimate vacuum of 0.5–1.0 mbar. Following evacuation, precise metering of inert gas is performed through solenoid valves and distribution manifolds to achieve the target gas composition and pressure within the container. The process is controlled to meet specified residual oxygen levels (0.5–2.0%) and cycle times (2–8 seconds). The system operates within defined temperature (5–40°C) and humidity (≤85% non-condensing) ranges to ensure pump performance and sealing integrity. The unit's operating pressure range is 1.0–1.6 MPa, and it is designed for integration with control systems that monitor and adjust gas flow and vacuum levels.
