The effect of humidity on food refrigeration.

Number: 244

Author(s) : CLELAND D. J.

Summary

After temperature, air relative humidity (RH) has important secondary impacts on food refrigeration. RH significantly affects both the storage life of many food products and the performance of the refrigeration system. Air RH is determined by the balance of moisture entry and removal. Quantitative methods to predict the main moisture transport processes due to door air infiltration, sorption by packaging, defrost, product weight loss, people and equipment, and dehumidification by the air-cooling coils are presented and solved iteratively to predict RH. A process freezer and coldstore are used to illustrate humidity management including how to increase or decrease RH; avoid particularly unfavourable frosting that causes very rapid deterioration in cooling coil performance, avoid condensation or icing on surfaces other than the coil, and to optimise defrost frequency.
