In a world where food safety and quality are undisputed priorities, innovation in preservation techniques is essential to ensure that products reach the end consumer in the best possible condition.
Advanced ultra-freezing techniques play a crucial role in this goal, enabling food preservation at extremely low temperatures, significantly reducing degradation and extending product shelf life.
At GasN2, we have developed a line of refrigeration products designed for various sectors, including food and chemical-pharmaceutical industries. This line combines the best aspects of mechanical and cryogenic refrigeration for refrigeration and freezing applications. Based on refrigerant compression and expansion systems, our products require no consumables and use environmentally friendly natural refrigerant gases with a Global Warming Potential (GWP) close to 0.
Importance of Ultra-Freezing in the Food Industry
Ultra-freezing is a food preservation method that has revolutionized the food industry thanks to its ability to preserve the quality, safety, and nutritional value of products. This process involves reducing the temperature of food much more quickly and powerfully than traditional freezing, achieving extremely low evaporation temperatures.
N2 Gas Ultra-Freezing Plants
All our equipment is designed to operate outdoors. The operating power ranges from 15 kW to 150 kW of cooling with a very low evaporation temperature.
There are different types of freezing tunnels, depending on whether the product remains static or in motion:
- Static freezing tunnels: The product remains static inside a blast chiller chamber during the freezing process.
- Dynamic freezing tunnels: The product moves along a conveyor belt where it enters the freezing tunnel.
Advantages of the technology
- Lower environmental impact: The carbon footprint of gas manufacturing is reduced.
- Cost control: Continuous cost control without unexpected price increases.
- The organoleptic properties (structure, color, aroma, etc.) of the product are maintained after freezing.
- Improved process efficiency: Shorter freezing time and higher production capacity.
- Elimination of tanker truck traffic: Reduction in associated CO2 emissions.
- Generation self-sufficiency: Eliminates dependence on an external supplier.
Solution Advantages
- High energy efficiency: High productivity with controlled and efficient consumption.
- More environmentally friendly natural refrigerants with a GWP close to 0.
- Reduced refrigerant charge: Minimum charge required in the cooling plant.
- Comprehensive alarm management: 4.0 technology for alarm management and control.
- Modular equipment: Modular configurations based on customer needs.
- Leak detectors and safety systems: Leak detection systems.
- Comprehensive system operation control platform: 4.0 technology for operational management and control.
- Remote control: Remote control and manipulation of the equipment.
- Data traceability: All information regarding equipment performance is tracked and documented.
Ultra-freezing represents a significant innovation in food preservation, offering multiple benefits in terms of quality, safety, and sustainability. Its implementation in the food industry not only improves product preservation but also contributes to reducing food waste and environmental impact. The adoption of advanced ultra-freezing technologies is therefore a key strategy for the sustainable development of the global food industry.
