Description

State of the art

[0001] Disposable barbecues are well known in the art and are often used on trips, festivals, in the park, or while camping. Common disposable barbecues typically consist of an aluminum tray filled with charcoal or charcoal briquettes. After use, these disposable barbecues are often disposed of, and the aluminum materials represent a significant environmental burden.

[0002] More environmentally friendly versions of disposable barbecues are also available, made from biodegradable materials such as plant fibers with mineral fillers. However, these typically require additional fuel such as coal or briquettes, which must be carried separately.

[0003] A major disadvantage of conventional disposable barbecues is that they remain hot for long periods after use and pose a significant fire hazard, especially when left in parks or at festivals. Fires caused by improperly disposed of disposable barbecues cause significant damage every year. Structure and advantages of the invention

[0004] The disposable barbecue device according to the invention consists of at least 60 percent by weight of compressed volcanic rock powder as the main component. It also contains natural binders, in particular clay and / or water glass, which typically make up 15 to 25 percent by weight of the total mixture, as well as vegetable charcoal in a proportion of 5 to 20 percent by weight, which is homogeneously distributed throughout the material matrix.

[0005] The disposable grill has a bowl-shaped design with a reinforced rim and features several air channels arranged at regular intervals. These air channels have a diameter of approximately 3 to 10 mm and penetrate the grill completely or partially to ensure optimal oxygen supply.

[0006] The bottom of the grill features thermal insulation in the form of a layer of increased porosity to prevent overheating of the surface. The top is designed to serve directly as a grilling surface, without the need for a separate grate.

[0007] In a preferred embodiment, the disposable grill device additionally contains integrated, heat-activated flavor capsules. These flavor capsules are embedded in the material matrix and contain natural oils or spices that are released upon heating, imparting a special flavor to the grilled food.

[0008] The disposable grill is manufactured in different sizes: - A small version (S) with dimensions of approx. 20 cm × 15 cm and a weight of approx. 400 g, which is designed for 1-2 people and has a burning time of 45-60 minutes. - A medium version (M) with dimensions of approx. 30 cm x 20 cm and a weight of approx. 700 g, which is designed for 3-5 people and has a burning time of 60-90 minutes. - A large version (L) with dimensions of approx. 40 cm × 30 cm and a weight of approx. 1200 g, which is designed for 6-10 people and has a burning time of 90-120 minutes.

[0009] The disposable grill is manufactured by mixing the components, pressing the mixture into a grill tray mold at a pressure of 8 to 20 bar, and then drying it at a temperature between 60°C and 120°C for a period of 2 to 8 hours.

[0010] The disposable grill device according to the invention offers the following significant advantages over the prior art: 1. Functionality without external fuels: The addition of vegetable charcoal makes the grill functional without the need for external fuels. This simplifies handling and reduces the weight required. 2. Self-extinguishing properties: After the grilling process is complete, the grill extinguishes itself due to the specific composition and structure of the material. This significantly reduces the risk of fire, especially in public areas such as parks or festivals. 3. Environmentally friendly: The disposable grill is fully compostable after use. The mineral components of the volcanic rock even contribute to soil improvement. 4. Improved heat resistance: Due to the high proportion of volcanic rock powder as the main ingredient, significantly higher heat resistance and structural stability during the grilling process is achieved than with other biodegradable grills. 5. Flavor enhancement: The optional integrated flavor capsules offer the possibility of giving the grilled food a special flavor without the need for additional spices or marinades.

[0011] The disposable grill is activated by brushing it with a standard grill lighter and then igniting it. After about 15 minutes, it reaches the optimal grilling temperature. The maximum temperature in the center of the grill surface is approximately 350°C, which ensures optimal grilling results.

[0012] After the grilling process, the grill automatically extinguishes and cools down to ambient temperature after about 30 minutes. Once cooled, the grill can be crumbled and composted. After about three months, the material will be fully integrated into the compost, with the mineral components of the volcanic rock contributing to improving soil quality. SummaryVolcanic rock-based self-extinguishing disposable barbecue device

[0013] The invention relates to a disposable grilling device made of at least 60 percent by weight of pressed volcanic rock powder as its main component. The grilling device functions without the addition of external fuels because it contains vegetable charcoal in a proportion of 5 to 20 percent by weight, which is homogeneously distributed throughout the material matrix. A particularly advantageous property is the self-extinguishing property after the grilling process, which is achieved through the specific composition and structure of the material. The grilling device can have integrated, heat-activated aroma capsules as well as air channels to improve the oxygen supply. After use, the grilling device is fully compostable, and the mineral components of the volcanic rock can contribute to soil improvement.
