Application:
Mayonnaise producer wanted a complete system to inject nitrogen into product, resulting in smoother product texture, increased product volume and extended shelf-life. The package was to include not only the nitrogen injection body, but also the pressure regulator, metering system and valves mounted at a control box. The flow meter, mounted inside the box was to receive a 4-20mA control signal from the customer PLC.
Process Conditions:
Product Flow Rate: 35 GPM
Nitrogen Supply Pressure: 1500 PSIG regulated to 150 PSIG
Product Pressure: 40-60 PSIG
Nitrogen Flow Capacity: 33 SLPM
Solution:
Pick Model SC25 Nitrogen Injection System with 3” sanitary mixing chamber, isolated from N2 supply by sanitary check valve. System includes mass flow controller and 2-way solenoid valve wired to customer 4-20 mA control signal from PLC, installed in stainless steel NEMA 4 enclosure. Customer N2 supply is installed prior to high-pressure regulating valve. Compression fittings for customer piping between control panel and mixing chamber were included.
Features and Benefits:
• Complete Packaged System
• Low Maintenance
• Thorough Mixing
• Quick, Simple to Clean

Why Choose Direct Steam Injection for Food Processing?
Pick Heaters' direct steam injection technology provides rapid, precise heating for a wide range of food products, including sauces, dairy products, starches, slurries, and prepared foods. By delivering steam energy directly into the product stream, processors can achieve consistent temperatures, improve production efficiency, and maintain product quality. The gentle heating action helps preserve product characteristics while supporting sanitary processing requirements and continuous operation.
