Freezing is one of the oldest and most widely used methods of food preservation, which allows preservation of taste, texture, and nutritional value in foods better than any other method. The freezing process is a combination of the beneficial effects of low temperatures at which microorganisms cannot grow, chemical reactions are reduced, and cellular metabolic reactions are delayed (Delgado and Sun, 2000).
Bottom Drop Tunnel
Cryogenic tunnels are used for many applications. You can process any flow of product that must be continuously cooled, frozen, or crust frosen. The main applications are in the food industry.
Cryo Coating Tumbler
Manufacturing of convenience food and ready meal components. The substrate can be seafood, vegetables, meat, potatoes, pasta or other free rolling products.
Snow Horn - Snow Station
The food and pharmaceutical industries are our main customers for this unusual, vacuum-insulated system. Dohmeyer’s snow horn is used to create fine snowflakes that are used for chilling of minced meat, standardizing of meat paste, marzipan cooling, chocolate and chocolate paste production, crust freezing of surfaces, removal of process-generated heat in cutters, mixers and bowl choppers, dough mixers, etc
Top Lifting Tunnel
Cryogenic tunnels are used for many applications. You can process any flow of product that must be continuously cooled, frozen, or crust frozen. The main applications are in the food industry.
Crust freezing is an important use for cryogenic batch freezers in the food industry, for example in preparation for subsequent slicing. However, many producers also use them for normal freezing and/or cooling of meat, fish, prepared meals, bakery products, etc., because the total process cycle can be shorter than in a fixed trolley freezer, allowing higher productivity and production capacity
Cryo Roll drum freezers are best used for rubber chips of tyres, cables and other products.
Even very sticky products can to frozen, in that case we can cover the inner wall of the drum with a non-adhesive coating such as PTFE.
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.
