COLD CARRIER FOR COOLING AND FREEZING OF FOODS Russian patent published in 2005 - IPC

FIELD: food industry and refrigeration engineering.

SUBSTANCE: invention relates to cold carriers used in closed various-destination heat-exchange equipment and proposes cold carrier containing 15.0-96.7% ethyl alcohol, 0.01-0.10% turpentine, 0.038-0.390% corrosion inhibitor, and balance amount of water. Corrosion inhibitor is constituted by triethanolamine and phosphoric acid at ratio 5:1. Cold carrier is efficient within temperature range from 0 to 100°C, has low viscosity and thermophysical characteristics close to those of water. It is environmentally safe and not inflammable at temperatures below 10°C.

EFFECT: improved working characteristics.
