Cryogenic tunnel freezer for continuous cooling
In the food industry, maintaining product integrity during cooling and freezing is critical. Conventional methods often result in uneven temperatures and product degradation, presenting significant challenges, especially in mass production environments.
Continuous cooling and freezing with cryogenic technology
The Linear Tunnel – Top Lifting by Dohmeyer is a cryogenic tunnel that provides continuous cooling or freezing for various industrial applications. It uses liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) to achieve rapid temperature reduction. As products move along the conveyor belt, controlled cryogenic gas injection and efficient gas dispersion via turbulence fans ensure uniform cooling. This method leverages the latent heat of evaporation for optimal energy efficiency. Designed for adaptability, the Linear Tunnel – Top Lifting can be customized to meet specific requirements with high-performance thermal insulation of 140 mm thick. Primary applications include freezing, crust freezing, and cooling of food products, with the ability to process continuous product flow.
