Tray transport cart having electromagnetic induction heaters for heating meals to be placed on the trays |
摘要 |
A tray transport cart which accommodates trays for holding dishes for containing meals has a movable cart body with a plurality of tray carriers installed therein. Induction coils are inserted into the tray carriers for generating a local electromagnetic field. The trays hold the dishes which are provided with a current-conducting layer. An HF generator positioned on the cart body cooperates with the induction coils to produce the total inductance of the coils to generate a desired induction current in the current-conducting layer of the dishes, in the range between 32 mu H and 76 mu H, to maintain the meals contained in the dishes at warm temperatures.
