Cryogenic tunnel freezer for continuous cooling
Achieve precise and efficient cryogenic freezing for continuous production lines with this advanced tunnel freezer, designed to maintain optimal product quality while minimizing energy consumption.
Continuously Freezes and Cools Solid Foods
The Linear Tunnel Freezer – Top Lifting by Dohmeyer is engineered for efficient cryogenic processing, specifically for the fast-paced food industry. This top-lifting tunnel uses a conveyor system to facilitate continuous freezing and cooling of products such as frozen pizzas, seafood, and desserts. Utilizing liquefied carbon dioxide or nitrogen, it achieves rapid temperature reduction through the latent heat of evaporation. To ensure uniform cooling, turbulence fans disseminate cryogenic gases effectively across product surfaces, while exhaust fans safely remove residual gases.
With robust 140 mm thermal insulation, Dohmeyer’s tunnel freezers are highly effective in reducing energy consumption and ensuring process consistency. The equipment can be tailored to fit specific requirements, making it versatile for various applications from freezing to crust freezing. Automated PLC controls and remote monitoring support seamless integration into existing production lines, enhancing operational efficiency. Available with options for stainless steel construction, it meets industry standards for hygiene and durability, ensuring long-lasting performance.
