Industrial refrigeration are pioneers in promoting slurry ice systems to process industries.Slurry ice flowable is the mixture of ice crystal and water solution (usually sea water, brine, sweet water or glycol). It is also known as fluid ice, liquid ice, and so on. There are, usually, two ways to make slurry ice. Each way has its own features and advantages slurry ice can be made from broken solid ice and mixing with brine or sea water. However, the mixture still contains large and sharp ice crystals with thickness 0.6-10mm. Making this kind of slurry ice requires a large amount of energy, including energy consumption for ice breaking and grinding. Slurry ice can be made in pipe type evaporator. Brine or sweet water is pumped to internal pipe by water pump and the refrigerant circulates between inner and outer pipes. Ice crystal would be formed on the evaporator inner surface, at -8 -12 , and scraped down by the rotary ice scraper. The mixture of water and ice collected is slurry ice. Resulting from the heat exchange of ice phase and high heat transmission coefficient, evaporator size may be reduced eventually.
