Dohmeyer developed a range of large capacity freezers, known as the OptifreezeTM freezers. Optifreeze is the registered trade mark of Dohmeyer, representing a unique Spiral Freezer concept.
OptiFreezeTM has a unique horizontal airflow design that maintains the same air temperature and air speed throughout all levels, minimizing residence time for the food products and reducing weight loss to obtain a higher yield.
The horizontal airflow design generates flows up to 6m/s. The result is that every product, no matter of its location, is subject to the exact same airflow and therefore exits the freezer with a uniform temperature.
