Freezing
Ultra fast freezing with liquefied gases.
Producers of high quality food are deeply concerned with the flavour, moisture content and texture of the finished product. The speed of formation of ice crystals in the foodstuff is the key factor affecting these qualities.
Rapid freezing using cryogenic gases (liquid nitrogen, liquid carbon dioxide or synthetic liquid air) gives you a frozen product that is more highly appreciated by the market.
Making use of the most innovative air flow control, results in a tunnel freezer with doubled heat exhange.
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.
Cryogenic tunnels using liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) with top lifting cover.
Cryogenic tunnels use liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) for continuous cooling and freezing.
Linear freezing tunnel with multiple superposed conveyor belts move the product backwards and forwards through the freezer.
Drum freezer for continuous freezing of free rolling products.
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.
Cryogenic batch freezers use liquefied carbon dioxide (LCO2) or liquefied nitrogen (LIN) for discontinuous cooling and freezing made with rotating trolley for superb homogeneous cooling and freezing.
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.
