Liquid nitrogen freezer for sensitive food and fermentation ingredients
Achieve rapid, uniform freezing of sensitive food and fermentation-derived products, maintaining their quality and bioactivity, while reducing process time and ensuring ease of handling and storage.
Freezes and Pelletizes Sensitive Liquid Products
The Liquid Nitrogen Freezer range from GEA, including models LNF-6, LNF-100, LNF-220, and LNF-500, is designed to efficiently freeze and pelletize sensitive liquid products across various industries. Utilizing liquid nitrogen at -196 °C, it rapidly freezes products into uniformly sized pellets, crucial for the preservation of sensitive products like microbial cells and enzymes.
Commonly integrated into food, beverage, and pharmaceutical production lines, the freezer supports applications ranging from instant coffee granules to active bacterial starters. Its compact design features a motorized agitator to prevent agglomeration and a CIP-compatible system to ensure hygienic operation.
With throughput capacities ranging from 100 to 500 kg/h, the GEA Liquid Nitrogen Freezer is available in several industrial sizes and a pilot unit for batch trials, making it suitable for both small-scale testing and large-scale production. The system effectively reduces processing time and enhances product quality, while its modular design allows for easy installation and maintenance.
Additionally, the system offers substantial operational savings through minimal product loss and simple maintenance, supporting sustainable production practices.
