Nitrogen
The LND Liquid Nitrogen Tunnel Quick-freezing Equipment is an advanced industrial cryogenic freezing solution specifically engineered for high-value fruit processing, particularly durian. Manufactured by IQFJ Machinery, this liquid nitrogen IQF freezer utilizes ultra-low temperature nitrogen (boiling point: -196°C) as the refrigerant to achieve rapid, uniform freezing through a continuous belt-driven tunnel system, making it the ideal solution for durian processors aiming to expand export capabilities while preserving premium product quality
When liquid nitrogen comes into contact with the food surface, it instantly vaporizes and creates a powerful heat exchange that rapidly reduces the temperature of the food at a rate 5 to 10 times faster than conventional mechanical freezing. This ultra-fast freezing allows the product to pass quickly through the critical ice crystal formation zone (0°C to -5°C), resulting in the formation of fine, uniform intracellular ice crystals. Since small ice crystals do not rupture cell walls, the original texture, structure, and moisture content of the fruit are preserved. During thawing, juice and nutrient loss are minimized, ensuring that the durian retains its natural flavor, aroma, and mouthfeel
