Nitrogen Generation for Food Processing & Packaging
Preserve freshness, extend shelf life, and cut costs with right-sized nitrogen systems
Why Sacramento Food Processors Choose On-Site Nitrogen
Sacramento and the Central Valley form one of the largest food processing hubs in North America. With 67 food manufacturing companies in the region - from Blue Diamond Growers (829 employees, world’s largest almond processor) to Nugget Markets and dozens of specialty processors - the demand for nitrogen is massive and growing.
Food processing nitrogen applications:
- Modified Atmosphere Packaging (MAP)
- Product preservation and oxidation prevention
- Inerting storage tanks and silos
- Freezing and cryogenic applications (high-purity needs)
- Cleaning and purging production lines
- Pneumatic conveying systems
- Pressurizing packaging equipment
The cost of delivered nitrogen for these applications can exceed $50,000-250,000 annually for medium to large processors. On-site generation typically saves 50-80% while improving reliability and quality control.
Food Processing Nitrogen Requirements
Purity Specifications by Application
Modified Atmosphere Packaging (99.5-99.9% purity):
- Extending shelf life for fresh produce, nuts, baked goods
- Displacing oxygen to prevent oxidation
- Maintaining product quality during distribution
- FDA compliance for food-contact gas
Product Preservation (99.0-99.5% purity):
- Tank blanketing for oils, fats, wine, juice
- Preventing oxidation during storage
- Maintaining flavor and nutritional value
- Reducing waste from spoilage
Freezing Applications (99.99%+ purity):
- Cryogenic freezing for premium products
- Flash freezing to lock in quality
- Controlled atmosphere storage
- Temperature-critical applications
General Processing (95-99% purity):
- Pneumatic conveying
- Equipment pressurization
- Cleaning and purging
- Inerting production areas
Demand Pattern Challenges
Food processing has unique consumption patterns that standard sizing calculations miss:
Seasonal Variations:
- Harvest season (Sept-Nov): Up to 3x normal demand for nut processors
- Holiday peaks: Baking, confection, specialty foods surge
- Summer production: Fresh produce and beverage processing peaks
- Off-season: Reduced demand, system efficiency critical
Production Schedule Variations:
- Shift differentials (1st shift vs 2nd/3rd)
- Weekend vs weekday production
- Campaign production (batch vs continuous)
- Contract packing seasonal surges
Why measurement matters:
- A system sized for peak harvest may be 70% idle 8 months/year (energy waste)
- A system sized for average demand won’t handle peak season (production delays)
- Our approach: Right-size for actual peak demands with efficient turn-down capability

Common Food Processing Sizing Mistakes
The “Safety Margin” Problem
Scenario: A nut processor packages 50,000 lbs/day during harvest season (Sept-Nov) and 15,000 lbs/day the rest of the year.
Traditional vendor approach:
- Calculate peak harvest nitrogen consumption: ~180 SCFM
- Add 30-40% “safety margin”: Recommend 250-300 SCFM system
- Quote $180,000-220,000 installed
What actually happens:
- System runs at 60-70% capacity during peak (inefficient)
- System runs at 20-30% capacity off-season (very inefficient)
- Energy waste: ~$15,000/year
- Maintenance costs higher (poor cycling)
- Capital waste: $60,000-80,000 oversizing
Our measurement-based approach:
- Log actual consumption for 30-45 days (including peak season if possible)
- Measure true peak demand: Often 120-150 SCFM (not the estimated 180)
- Right-size: 160-180 SCFM system with turn-down capability
- Quote: $95,000-115,000 installed
Results:
- Perfect capacity for actual needs
- Efficient operation at all production levels
- Capital savings: $65,000-105,000
- Energy savings: $12,000-15,000/year
- Faster payback, higher ROI
Food Safety & Compliance Considerations
FDA Requirements for Food-Contact Nitrogen
On-site nitrogen generation must meet strict food safety standards:
Purity Standards:
- Food-grade nitrogen (21 CFR 184.1540)
- No oil contamination (oil-free compression or filtration)
- Regular purity testing and documentation
- Certificates of compliance
System Design Requirements:
- Stainless steel or food-grade piping where necessary
- Filtration to remove particles and potential contaminants
- Dew point control (moisture removal)
- Monitoring and alarm systems
Our systems include:
- ✅ Oil-free compressor or multi-stage filtration
- ✅ Activated carbon filtration for oil vapor removal
- ✅ Particulate filtration (0.01 micron)
- ✅ Dew point monitoring
- ✅ Continuous purity verification
- ✅ Compliance documentation and certificates
HACCP Integration
Modern nitrogen systems integrate with Hazard Analysis Critical Control Points:
- Real-time purity monitoring (Critical Control Point)
- Automated alerts for out-of-spec conditions
- Data logging for compliance audits
- Preventive maintenance schedules
- Backup systems and redundancy planning
Case Study: Sacramento Nut Processor
See full case study: Food Processing Company Cuts Nitrogen Costs by 62%
Challenge: 800+ employee nut processor was quoted $215,000-285,000 for nitrogen systems based on estimated usage.
Our Approach: 30-day data logging during harvest season revealed actual peak demand of 182 SCFM vs. estimated 450-550 SCFM.
Results:
- System cost: $68,000 (68% capital savings)
- Annual savings: $43,100/year vs. delivered nitrogen
- Payback: 18 months
- 10-year NPV: $387,000
Key insight: The national vendors recommended systems 2.5-3x larger than needed, wasting $147,000 in capital and $18,000/year in energy.
