Revolutionizing Food Packaging: Leybold’s Vacuum Solutions for Freshness and Efficiency

In the fast-paced world of food production, maintaining freshness, aroma, and texture is paramount. Vacuum packaging plays a critical role in extending shelf life, preventing contamination, and enhancing food safety. Leybold’s advanced vacuum solutions for food packaging combine cutting-edge technology with reliability, ensuring optimal performance for various packaging methods. From Modified Atmosphere Packaging (MAP) to skin packaging and rotary chamber machines, Leybold’s pumps deliver unmatched efficiency, sustainability, and cost-effectiveness.

Key Vacuum Packaging Methods
1. Modified Atmosphere Packaging (MAP)
MAP replaces the air inside packaging with a protective gas mixture (e.g., nitrogen, carbon dioxide) to slow oxidation and microbial growth. Leybold’s solutions include:

SOGEVAC Oil-Sealed Pumps: High pumping speeds and low ultimate pressure (down to 0.08 mbar) ensure rapid evacuation, reducing cycle times.

NOVADRY Dry Screw Pumps: Ideal for red meat MAP with oxygen compatibility—no oil contamination risk and NSF H1-certified options available.

Benefits:

Longer shelf life for products like fresh meat, seafood, and dairy.

Energy-efficient operation with reduced maintenance.

2. Skin Packaging
Skin packaging minimizes plastic use while enhancing product presentation and shelf life. Leybold’s NOVADRY and DRYVAC pumps excel here due to:

Compact Design: Can be installed directly near packaging machines, eliminating long pipelines that slow evacuation.

Low Noise & Heat: Operate at just 50–73 dB(A), suitable for production floors.

Application Example:

Heating and sealing films at low pressures (e.g., 1–10 mbar) to tightly wrap products like cheeses or cured meats.

3. Chamber Packaging Machines
Used for vacuum-sealed bags (e.g., for meats, nuts), these machines rely on:

SOGEVAC Rotary Vane Pumps: Proven technology for high-throughput single/double-chamber machines.

DRYVAC with RUVAC Roots Blowers: Combines dry screw pumps with boosters for large systems, cutting cycle times by 20%.

Innovation Spotlight:

NOVADRY NDi Systems: Centralized, oil-free vacuum systems with smart controls for multi-chamber setups.

4. Rotary (Carousel) Packaging
High-speed rotary machines for primal meat cuts benefit from:

DRYVAC + RUVAC Systems: Compact, low-energy setups installed adjacent to machines, avoiding energy losses from long pipes.

Energy Savings: Variable speed drives (VSD) adjust pumping speed to demand, reducing power use by up to 50%.

Leybold’s Standout Technologies
Dry Pumps for Hygiene & Efficiency
NOVADRY: 100% oil-free, air-cooled, and washdown-ready (with stainless enclosures). Perfect for MAP with O₂.

CLAWVAC CPi: Dry claw systems with corrosion-resistant rotors for harsh environments (e.g., slaughterhouses).

Oil-Sealed Pumps for Cost-Effective Performance
SOGEVAC SV B Series: NSF H1-certified oils ensure food safety; models like SV 750 B handle 755 m³/h for large thermoformers.

VACUBE: Intelligent screw pumps with VSD technology for central vacuum systems, optimizing energy use.

Accessories for Enhanced Performance
LF Filters: Triple-protection liquid/dust separators for pump longevity.

PIEZOVAC Gauges: Monitor vacuum levels in real-time to ensure seal quality.

Sustainability & Total Cost of Ownership
Leybold’s solutions prioritize sustainability:

Water Savings: e.g., Beer Bottling Vacuum Systems replace water-intensive liquid ring pumps, cutting usage by 100%.

Energy Efficiency: DRYVAC and VACUBE reduce power consumption by 20–50% versus traditional pumps.

Low Maintenance: Dry technologies (NOVADRY, CLAWVAC) slash servicing costs and downtime.


Leybold’s vacuum solutions redefine food packaging by merging innovation with practicality. Whether it’s extending shelf life via MAP, reducing plastic in skin packaging, or accelerating rotary machine throughput, Leybold’s pumps deliver precision, reliability, and sustainability. By minimizing energy use, maintenance, and contamination risks, these technologies help producers meet both economic and environmental goals.
