Vacuum Solutions for Food Processing: Enhancing Quality and Extending Shelf Life

The modern food industry faces two key challenges: maintaining product quality and reducing microbiological contamination risks. Leybold’s vacuum technologies offer innovative solutions for food processing, packaging, and storage, ensuring maximum freshness, safety, and cost efficiency.

In this article, we explore how vacuum systems are applied across food processing—from vacuum cooling and drying to filling and product conveying.

Key Applications of Vacuum Technology in Food Processing
1. Vacuum Cooling
Principle: Rapid temperature reduction through moisture evaporation under vacuum.
Benefits:
✔ 5–10 times faster than traditional cooling methods
✔ Minimizes product weight loss
✔ Extends shelf life (especially for leafy greens, baked goods, rice)

Recommended Solutions:

SOGEVAC (small-scale lines)

DRYVAC and NOVADRY (industrial-scale operations)

2. Drying & Freeze Drying (Lyophilization)
Principle: Removing moisture at low temperatures to preserve nutrients.
Applications:

Instant coffee, dried fruits, spices

Lyophilized meat, berries, ready-to-eat meals

Leybold Advantages:
✔ SCREWLINE – The only system with on-site cleanability
✔ NOVADRY – 100% oil-free for maximum safety
✔ RUVAC + SOGEVAC – High-performance combo for industrial lines

3. Waste & Raw Material Conveying
Challenge: In meat processing, vacuum transports waste, deboning, and poultry evisceration. Conventional pumps fail due to fat, water, and meat particles.

Solution:

CLAWVAC CPi – Dry claw pumps with corrosion-resistant rotors

Hygienic washdown-ready designs

Result:
✔ 30–50% less downtime
✔ Lower maintenance costs

4. Meat Tumbling & Marination
Technology: Vacuum enhances marinade penetration, speeds up processing, and improves product quality.

Pump Selection:

SOGEVAC – Standard processes

NOVADRY – Harsh environments (high salt/acid content)

Effect:
✔ Even spice distribution
✔ Higher product yield

5. Vacuum Filling & Forming
Examples:

Sausages, alternative protein products

Vacuum-formed semi-finished goods

Optimal Systems:

SOGEVAC SV B – Small filling machines

NOVADRY – Large-scale production (up to 20% energy savings)
