A super-quick freezing method and apparatus for preserving the freshness of food ingredients and food products while enabling long-term storage is provided. Provided is a freezing store 11 capable of lowering the inner-temperature to -30°C to -100°C; and a fluctuating magnetic field generator 21 for applying a unidirectional magnetic field, which fluctuates within a predetermined range about a fixed reference value with an arbitrary intensity in the positive and negative directions, to the central portion of the store. Also provided are ventilators 31 for circulating cold air within the store at a wind velocity of 1 to 5 m/sec; and a sound wave generator 41 for superimposing sound waves in the audio-frequency range [with a sound pressure level of 2 to 10 dB] onto the cold wind circulated by the ventilators 31. Also provided is an electric field generator 51 for applying an electric field [with an intensity of 100 to 1000 kV/m] to the central portion of the store. The fluctuating magnetic field generator 21 comprises permanent magnets 21a for applying a static magnetic field with the intensity of said reference value to the central portion of the store, and electromagnetic coils 21b for applying a fluctuating magnetic field, which fluctuated within predetermined range about the static magnetic field, to the central portion of the store.
L'invention concerne un procédé et appareil de congélation rapide pour conserver les aliments frais pendant longtemps. Un congélateur (11) maintient la température dans une plage allant de 30 à 100 DEG C. Un dispositif magnétique (21), doté d'un aimant permanent (21a) servant à produire un champ magnétique statique d'une intensité de référence dans le centre du congélateur et doté d'une bobine électromagnétique (21b) permettant de faire varier le champ magnétique au centre du congélateur, produit un champ magnétique, appliqué sur le centre du congélateur, dont l'intensité varie selon la valeur de référence. Une soufflerie (31) fait circuler de l'air froid à une vitesse de 1 à 5 m/sec dans le congélateur et un générateur de son (41) produit des ondes sonores audibles qui viennent s'ajouter à l'air froid qui est soufflé. Un dispositif (51) produit un champ électrique agissant sur le centre du congélateur.
