易い欠点があつた。3 Problems with the conventional technology However, with the conventional technology, the heat capacity of the entire heat transfer case increases due to the molding material, which has the disadvantage of poor followability to the temperature of the pan, resulting in large temperature ripples inside the pan. Sometimes, it takes time to dry the molding material, and the heat-sensitive element moves during drying, causing variations in the degree of contact with the heat transfer case, which has the disadvantage that the set temperature tends to vary.
