Supercooled ice slurry production: first results from a test plant.

Auteurs : BEDECARRATS J. P., STRUB F., DUMAS J. P., et al.


Ice slurry can be generated in different ways. One of them consists in producing ice from supercooled water. A stream of water, when cooled slowly, can be supercooled by several degrees below the normal freezing point without forming ice on the wall of the exchanger. After leaving the exchanger, the supercooled water flow is physically disturbed in order to generate ice crystals. The ice fraction depends on the level of supercooling of the liquid leaving the exchanger and increases by approximately 1.26%/°C supercooling. The first difficulty is to make the supercooled water flow. A test plant which has been devised will be presented. The supercooled water is a fluid which needs special care in handling. The influence of different parameters on the metastability breakdown have been studied: level of supercooling, flowrate, refrigerant fluid temperature. Ice crystal generation must be controlled. Different processes will be shown.
