Description

Title of the invention: Low-power induction warming system and adaptation kit for dishes

[0001] 1. Technical field

[0002] The present invention relates to a device for keeping food warm in dishes, more specifically a low-power induction heating system designed to prevent thermal alterations of food while minimizing the risk of burns.

[0003] 2. Prior art

[0004] Existing food warming systems in catering or institutional settings generally rely on the use of infrared lamps or microwave ovens. These methods have several drawbacks:

[0005] - The lamps heat up in a localized way, leading to drying or a overheating of the food surface.

[0006] - Microwaves can alter the texture of food (rubbery effect).

[0007] - These devices present an increased risk of burns for users (servers notably).

[0008] - The dishes cool down rapidly once removed from the device.

[0009] 3. Summary of the invention

[0010] The present invention proposes an innovative food warming system based on the use of a low-power induction cookware set, powered by a direct current source. The system also includes a conversion kit allowing any type of non-magnetic cookware to be adapted to the properties necessary for induction compatibility.

[0011] The device allows for the delivery of an adjustable final power output between 200W and 600W, sufficient to keep food at temperature without cooking it or altering its texture.

[0012] 4. Detailed description

[0013] 4.1 System Composition

[0014] - Low power induction set: Flat induction heating surface, powered by a direct current source.

[0015] - Dish transformation kit: Removable or adhesive element (e.g., disc) (metallic) to be fixed under the dishes.

[0016] - Integrated thermal regulation: Allows precise temperature control.

[0017] 4.2 Technical characteristics

[0018] - Power range: 200 to 600 Watts

[0019] - Power supply: direct current (DC)

[0020] - Compatibility: All tableware thanks to the conversion kit

[0021] - Safety: Cold surface outside the dishwashing contact area

[0022] 5. Advantages of the invention

[0023] - Maintaining a homogeneous and constant temperature without altering the consistency of food

[0024] - Reduction of burn risks for personnel

[0025] - Easy to adapt to all types of tableware

[0026] - Silent and energy-efficient

[0027] - Compatible with mobile or network-isolated environments

[0028] 6. Claims

[0029] 1. A system for keeping a food container warm, comprising:

[0030] - a low-power induction heating device powered by current continuous,

[0031] - and an adapter kit to make any non-inductive container compatible with said induction.

[0032] 2. The system according to claim 1, characterized in that the power delivered is between 200W and 1000W.

[0033] 3. The system according to any one of the preceding claims, in which the kit The adapter includes a metal disc to be fixed under the dishes.

[0034] 4. The system according to any one of the preceding claims, in which the temperature is controlled to ensure that it does not exceed a threshold of 70°C to 80°C.
