Resum

The present work presents experimental results of the production of ice slurry in aninnovative scraped-surface plate heat exchanger (SSPHE). It consists of a 28 liters capacity tank with a total heat transfer area of 10m2m-3 crystallizer volume. The scraper consists of four rotating PEEK blades that are driven by a vertical shaft connected to an electrical motor.The heat transfer surface is cooled underneath by a foow of calcium chloride solution in water.The coolant solution is subsequently cooled by the expansion of a flow of R507 refrigerant in a compact evaporator. Sodium chloride brine with a concentration of 5% is the base solution for the generation of ice slurries of about 20% of ice content in a batch process.
