Abstract

Dispositif de chauffage à haute fréquence pouvant détecter les variations d'humidité et de température dans la vapeur produite par le chauffage d'aliments (14) dans une chambre de chauffage (13) en utilisant un détecteur de température et d'humidité relative (17), et qui les convertit en des valeurs d'humidité relative et absolues pour déterminer si la variation de l'humidité absolue a atteint un niveau prédéterminé, ce qui lui permet de chauffer ou de refroidir automatiquement l'aliment. Etant donné que ce dispositif possède un seul détecteur, les erreurs dues à la détection et aux variations dans le temps sont réduites, et l'on obtient une détection précise.
