Dohmeyer Cyrogenic Batch Freezer

Dohmeyer Cyrogenic Batch Freezer

Cryogenic Food Freezing Cabinets Dohmeyer cryogenic batch freezers are used for discontinuous cooling, freezing or crust-freezing for a wide range of food products including meat, fish, vegetables and poultry in food factories. Controlled injection of the cryogenic gas lowers the temperature in the cabinet as the gas immediately evaporates. The latent heat of evaporation is the main source of cooling energy. Fans spread the gas in the cabinet in a controlled way and efficiently transfer the cold to the product’s surface. Applications Cryogenic batch freezers are used for discontinuous cooling, freezing or crust-freezing for a wide range of food products.  Normally the operator loads the product onto trolleys equipped with wheels, before pushing them into the freezer. Features and Benefits Although Dohmeyer’s batch freezers exist in standard dimensions, we can design tailor made cabinets that suit the specific needs of any individual application. Dohmeyer’s batch freezers have walls with 140 mm of high performance thermal insulation. Thanks to vacuum insulation the floor is very low (26mm), with the entrance ramp integrated into the floor.

Dohmeyer CryoRoll for IQF Food Freezing

Dohmeyer CryoRoll for IQF Food Freezing

IQF Freezing of Food The Dohmeyer CyroRoll is ideal for industrial IQF freezing of food products including meat, fish, shellfish, poultry, pasta and vegetables in food factories.  These rotary drum freezers consist of a sloping cylindrical drum, which rotates around its axis. Product and cooling medium are loaded continuously at the highest entrance point of the drum. By the rotating movement, both are intensively mixed while, at the same time, sliding to the lower exit of the drum. The stirring movement and the mixing prevent products from clumping together. Special paddles can be built in to ensure this happens. Both liquid nitrogen (LIN) and liquid carbon dioxide (LCO2) can be used as cooling liquid. Exhaust fans at inlet and outlet extract the residual gases. Product infeed Rotary drum freezers require continuous input of product. Dohmeyer can supply buffer hoppers and supply conveyors to convert discontinuous product flows into continuous input. Applications Rotary drum freezers are best used for IQF freezing of free rolling, mostly small products. They are perfect for products consisting of separate pieces.  Applications in the food industry are abundant: rotary drums freeze individual pieces (granules, crumps, cubes.. ) of fish and meat, pasta, vegetables and precooked dishes to IQF quality. When wet or sticky products need to be frozen, we can cover the inner wall of the drum with a non-adhesive coating such as PTFE. Unique double drum design For certain products it is best to use a double drum:  the first, short and fast turning drum serves to freeze the surface of the product, the second, long and slow turning drum freezes the product in depth. Features and Benefits Dohmeyer’s cryogenic rotary drum freezers can be tailor made. Inclination, rotating speed, baffles,… can all be adapted to the specific needs of the customer. Rotary drum freezers are compact and often take up less space than other types of IQF freezing...
