Cryogenic immersion bath for rapid freezing
Achieve rapid and intense cooling by immersing products in liquid nitrogen, ideal for processes requiring quick freezing or pre-cooling to maintain quality and integrity.
Rapidly Freezes and Prepares Industrial Products
Dohmeyer’s Cryogenic Immersion Bath Freezer is designed for rapid, efficient cooling across various industrial sectors, from food processing to metal and plastic recycling. This equipment stands out with its direct immersion process, utilizing liquid nitrogen at atmospheric pressure to rapidly bring products to extremely low temperatures, down to -195.8°C. Ideal for applications like freezing, crustfreezing, deburring, and cryofracturing, it accommodates both batch and continuous operations.
Optimized for integration in complex production lines, it serves as an effective pre-cooling unit before mechanical processes like shaping or coating. With customization capabilities, choose from conveyor belts, loading robots, lifting systems, and more to fit specific application requirements. Featuring thick polyurethane insulation or optional vacuum-insulated panels, this unit ensures safety and energy efficiency, minimizing the risk of ambient oxygen liquefaction.
Specifically engineered for high throughput, it handles a diverse range of solid and liquid products, such as frozen peas and recycled plastic flakes, contributing to efficient production workflows in industries including food, demilitarization, and waste management.
