INDUSTRIAL FREEZERS FOR FOOD UTILIZING CO2 PART 2: DEVELOPMENT AND TESTING OF A CO2 CASCADE SYSTEM, SPIRAL FREEZER AND ICE-CREAM FREEZER
In the past years, the use of CO2 has gained widespread acceptance as a natural refrigerant used in industrial freezing systems.Optimization of industrial freezing equipment using CO2 has been performed and tested. The higher capacity indicated by the developed simulation programmes was confirmed. The ice-cream freezer shows even higher capacity than predicted due to the better pool boiling of CO2. The air flow pattern in the spiral freezer was optimized using measurements and simulation (CFD).The tests were performed on full-sized equipment using a purpose built 100 kW CO2 cascade system including hot gas defrost by using only one compressor. The control strategy for both freezing and defrosting mode will be presented.
