Description

 Vertical barbecue for cooking on biofuels.

The claimed invention relates to household devices for fast, high-quality and safe for health food preparation in various conditions: outdoors, in a cafe, in a restaurant, a mobile food point.

Braziers are known in the prior art in which firewood or coals having a horizontal structure are used for heat treatment of products. The product is cooked according to the classical scheme: smoldering charcoal from below, skewers with cooked products from above.

 The disadvantages of these barbecue designs are the difficulties in maintaining the roasting regime, it is necessary to extinguish the flame on coals periodically, due to the ingestion of fat from the product, carcinogens appear that cause the formation of cancer cells in the human body, and the cooked product burns, which in turn makes it impossible to evenly fry cooked product.

 Braziers with a vertical structure are known.

From the utility model patent of the Russian Federation N ° 75922 dated January 21, 2008, an electric barbecue is known in which skewers with cooking products are arranged vertically.

 The disadvantage of this device is the absence in the cooking products (in barbecue) of generally accepted taste, for example, the smell of smoke. It is not possible to use this device in the field.

 From the patent for a utility model of the Russian Federation N ° 108938 dated 10.10.201 1, a device for heat treatment of products is known, comprising a base, a perforated hopper with holes for loading fuel, lower and upper disks with openings and grooves arranged in diameter for installing and rotating skewers around its axis. Moreover, the perforated heating hopper has a vertical cylindrical structure, a vertical installation of skewers and an electric gearbox.

 The disadvantages of this device are the low utilization of the heat of combustion of the fuel due to the release of most of it into the atmosphere, which in turn leads to a significant increase in the time of heat treatment of the product, uneven heating, insufficient fire safety. The layout of this device eliminates the possibility of manual rotation of the skewers in the absence of an electric gearbox, because the possibility of a burn from the rising heat of hot coals is not excluded.

From the utility model patent of the Russian Federation 3 2121715 dated 11/10/2012, a closed type barbecue is known, comprising a housing in which the product is heat treated, a furnace for loading and burning fuel, a lid having a central hole into which an exhaust pipe and openings for skewers are inserted. The disadvantages of this device are the lack of a generally accepted smell of smoke in the barbecue, due to the lack of direct exposure to the cooked product of hot coals. The fuel is set on fire, after its ignition, the walls of the furnace are heated, which (the wall) in turn transfers heat to the product. The lack of visual control of the preparation of the product, since this device has a closed design, and as a result, the lack of creative participation.

 The technical result of the claimed invention is the creation of simple designs and easy-to-operate vertical barbecues, providing high quality cooking of food products, mainly kebabs, kebabs on biofuels (mainly charcoal). These quality indicators are achieved due to uniform heat treatment and the absence of the appearance of polyaromatic hydrocarbons, carcinogens, which cause the formation of cancer cells in the human body. The inventive design of the vertical barbecue is half-open, which allows you to visually monitor the process of cooking the product and take part in this process directly, as traditionally cooking kebab is a creative process.

The main purpose of the barbecue is the preparation of barbecue. The presented design of the barbecue involves the manual rotation of each skewer, which introduces an element of creativity in the cooking process, takes attention throughout the entire preparation of the kebab, which eliminates the marriage and thereby achieves high taste qualities of the kebab and uniform roasting.

The technical result is achieved due to the fact that the vertical brazier consists of a metal cone-shaped body mounted on a flat platform that is the bottom, the bottom has a hole in the center into which the heating unit is installed, which has a mesh metal cone-shaped box for loading fuel into it, has an air duct separated from the cone-shaped the box with a mesh element to prevent fuel from falling out of the cone-shaped box, in addition, the box has the shape of a cone, expanding from its base upwards , along the bottom perimeter, between the cone-shaped box and the beginning of the cone-shaped body there are openings for installing skewer sting in them, and there are also large-diameter conical openings for the drain of fat and juice secreted by the cooking products during heating, there are cut-off bumpers in the upper part of the conical body rising hot air, there are grooves in the sides for fixing skewers in them, in addition, holes for skewers stings in the bottom and grooves for fixing skewers in the sides are made in such a way that when fixed in them, skewers with cooked products are located in the space between the mesh box with combustion products and the cone-shaped body, and are located parallel to the line of the side surface of the box, or at a slight inclination to it, the design of the vertical barbecue has supports.

The metal conical body can be made all-metal and mounted on a flat platform that is the bottom. The metal cone-shaped body can be made collapsible and installed on a flat platform that is the bottom.

 Mesh metal cone-shaped box for loading fuel into it contains at least one active side, which can be made of expanded metal sheet

The mesh metal cone-shaped box for loading fuel into it contains at least one active side, which can be made of mesh or perforated metal sheet.

 The inclination of the jumpers of the cut-out cells of the walls of the mesh metal cone-shaped duct for loading fuel made of expanded metal sheets into it is oriented in such a way that the end of the bulkhead is lower in the inner part of the duct than on the outer part of the duct.

 The air duct has openings for air supply and fuel combustion in a cone-shaped duct with the shutter closed.

The duct has a damper.

 The heating unit comprises at least one fixing flange. The heating unit may be removable.

 The heating unit can be manufactured by casting methods.

 The vertical barbecue can contain a pan for collecting fat and juice secreted by the cooking products during heating.

The vertical barbecue can be placed on supports of open or closed type, and can be made of stone or brick.

 The process of cooking barbecue is close to traditional, with a smoke. The products are prepared on charcoal, but the juice and fat from the product do not get on the coals and elements heated by its heat, there are no carcinogens.

The vertical brazier consists of a metal cone-shaped case (1) mounted on a flat platform that is the bottom (3), the bottom has a hole in the center into which a heating unit is installed, having a mesh (perforated) metal cone-shaped box (2) for loading fuel (wood coal, wood blocks, etc.). The box (2) has the shape of a cone expanding from its base upward, this form simplifies the laying of charcoal and its addition during the preparation of the product. The box (2) is rigidly connected to the duct (4), separated from the cone-shaped box (2) by a mesh element to prevent fuel from falling out of the cone-shaped box. The air duct has openings to maintain traction and a damper holding the ash from burned coal. An isothermal zone is formed between the duct (2) and the walls of the housing (1). Along the perimeter of the bottom (3), between the box (2) and the beginning of the body cone (1) there are holes (5) for installing skewers in them, and there are also large diameter conical holes (not shown in Fig. 1) for the drain of fat and juice secreted by the cooking products during heating. In the upper part of the conical body (1) there are bumpers (6) that cut off the flow of ascending hot air, in the bumpers there are grooves (7) for fixing the skewers body in them. Skewers (8) with the prepared product are located in the space between the cone-shaped duct (2) with the combustion products and the body (1) and are located parallel to the line of the side surface of the conical duct (2) or at a slight inclination to it. In this case, the heat from the fuel embedded in the box (2) directly affects the cooked product. In addition, the inclination of the skewers removes their upper part from the heat-affected zone, which even the rising heat is not dangerous when the skewers are rotated manually. The vertical barbecue is mounted on supports (9). With small dimensions of the vertical barbecue, 24 skewers can simultaneously be in it. The heating unit of this barbecue is removable. Brazier can be made rectangular, multifaceted, round configurations (forms), may have a tray for collecting fat and juice.

In the claimed brazier, the heating unit is removable, and has a vertically located metal box for loading fuel into it. The box has active sides and a cone shape expanding from its base upwards, also has an air duct with holes, which allows to achieve uniformity of temperature in the cooking zone of the product. The active sides of the box are made of expanded metal (mesh or perforated) sheet and are installed at an angle from the vertical axis. This slope allows you to increase the area of direct exposure to heat from the coals on the cooked product, the coals do not fall out of the box, and during the burnout process move inside the box, occupying a lower level of location. The box from the duct is separated by a mesh element holding the coals, and the damper keeps the ash from burnt coal. The built-in heating unit can be galvanized or made of stainless steel, as well as by casting, in the form of a rectangle, polygon, circle.
