Summary

IN RECENT YEARS THE AUTHORS HAVE CONDUCTED RESEARCH ON THE FEASIBILITY OF USING LIQUID CO2 IN CHINA FOR THE CHILLING, FREEZING AND TRANSPORT OF AQUATIC PRODUCTS. 4 KINDS OF CHILLING AND FREEZING TECHNOLOGIES WERE DEVISED AND A SPRAY APPARATUS WAS CONSTRUCTED. EXPERIMENTS HAVE PROVED THAT THIS TECHNOLOGY IS QUITE SATISFACTORY. THE FREEZING TIME OF ORDINARY FISH BLOCKS IS ONLY 25-30 MIN, WITH A FREEZING VELOCITY OF 1.7 MM/MIN WHICH IS ONLY 1/20-1/30 OF THE FREEZING TIME OF A CONVENTIONAL BLAST FREEZER. AT THE SAME TIME, DESICCATION LOSS IS MUCH REDUCED, BEING ONLY ONE THIRD OF THE CONVENTIONAL METHOD. FREEZING COSTS ARE SOMEWHAT HIGHER.
