Summary

IN ORDER TO MAINTAIN THE QUALITY OF PRODUCTS DURING AND AFTER FREEZING, SOME RULES SHOULD BE FOLLOWED. FIRSTLY, THOSE CONCERNING FOOD QUALITY, INITIAL QUALITY AND FREEZING SUITABILITY. SECONDLY, THE OPERATING CONDITIONS OF TUNNELS: REFRIGERATING CAPACITY, AMBIENT TEMPERATURE TO OBTAIN AND HOMOGENEOUS VENTILATION WHICH SHOULD BE MONITORED BY RECORDING THE CORE TEMPERATURE OF PRODUCTS. FINALLY, THE FREEZING TIME SHOULD BE DETERMINED NOT ONLY IN FUNCTION OF EQUIPMENT CHARACTERISTICS, BUT ALSO THOSE OF THE PRODUCT ITSELF, MAINLY ITS PACKAGING.
