Cooling

Rapid cooling using cryogenic gases

Dohmeyer offers solutions both for batch and continuous processes. We can advise you on the right equipment for different phases of production (liquid, solid, paste) of finished or semi finished prepared foodstuffs.  

Linear Tunnel - Top lifting

Cryogenic tunnels using liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) with top lifting cover

Linear Tunnel - Bottom drop

Cryogenic tunnels use liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) for continuous cooling and freezing

Multibelt freezer

Linear freezing tunnel with multiple superposed conveyor belts move the product backwards and forwards through the freezer.

CryoRoll for IQF foodstuffs

Drum freezer for continuous freezing of free rolling products

Batch freezer

Cryogenic batch freezers use liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) for discontinuous cooling and freezing. 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.

Rotating Cabinet

Cryogenic batch freezers use liquefied carbon dioxide (CO2) or liquefied nitrogen (LIN) for discontinuous cooling and freezing made with rotating trolley for superb homogeneous cooling and freezing

Screw Conveyor

Cryogenic screw conveyors can be used in conjunction with both continuous and batch production systems

Immersion bath

Immersion bath freezers consist of a liquid nitrogen (LIN) bath, in which you can rapidly freeze products to very low temperatures by direct immersion in the cryogenic liquid at atmospheric pressure.
