Description

The utility model relates to devices for the thermal processing of food products, mainly meat products: pork, beef, sausages, sausages, poultry, fish, lard, etc. outdoors.

The well-known standard design of the barbecue for classic cooking (smoldering charcoal from below, skewers with cooking products from above).

The disadvantage of such designs is the difficulty in maintaining the roasting mode, that is, you have to periodically extinguish the flame on the coals due to the ingress of fat from the product on hot coals. There is no way to evenly fry the product, it burns, carcinogens appear in the product, which contribute to the formation of cancer cells in the human body.

A device for heat treatment of products is known, containing a base, a perforated hopper with holes for loading fuel, lower and upper disks with openings and grooves arranged along the diameter for installing and rotating skewers around its axis. The perforated heating hopper has a vertical design of the heating part of the installation, a vertical installation of skewers and an electric reducer (RU 108938, IPC A47J 37/04, published on 10/10/2011).

The disadvantage of this device is 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. The layout of this device eliminates the possibility of manual rotation of the skewers in the absence of an electric gearbox, so the possibility of burns from the rising heat of hot coals is not ruled out.

Known brazier of the closed type, consisting of a housing, a lid having a central hole, a furnace with a grill, bottoms with a welded collector glass, an exhaust pipe, skewers, two handles. The brazier has a housing for heat treatment of the product, a furnace with a grill for loading and burning fuel, separated from each other, and a bottom with a collection glass (patent RU 121715, IPC A47J 37/04, published on November 10, 2012).

A disadvantage of the known device is 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. There is also no visual control of product preparation (since this device has a closed design) and, as a result, there is no possibility of creative participation in the process.

Known travel device for heat treatment of food products, including a folding barbecue with the possibility of its placement in a flat shipping container, made in the form of a rectangular housing for fuel, equipped with pivotally supported supporting elements. The fuel casing is installed vertically, equipped with a lid and made mesh, on the opposite side walls of the casing are mounted holder screens for fixing products on the side of the heat source, having grooves on both sides, a tray and a waste tray are placed under the casing (patent RU 59384, IPC A47J 37/06, published on December 27, 2006). The device is taken as a prototype.

The disadvantage of the analogue is that the housing for fuel is made in the form of a grid, and with repeated use, deformation of the housing reduces reliability and limits the service life of the barbecue. Also, the support elements on the hinges do not provide reliable stability during repeated use. In addition, the shape of the grooves on the screens of the holders complicates the rotation of the skewers during cooking, which leads to uneven thermal effects on the product.

The objective of the utility model is to create a collapsible barbecue, providing high quality cooking, mainly kebab.

EFFECT: increased rigidity of a folding brazier design.

The problem is solved, and the technical result is achieved by a device for heat treatment of food products made in the form of a folding barbecue with the possibility of its placement in a flat shipping container having a vertically oriented rectangular housing for fuel, front, rear and side walls, supporting elements, holders for fixing food products to the side of the heat source. Unlike the prototype, the casing is made of prefabricated flat parts made of sheet steel with hooks at the ends of the parts and mating mounting holes, with the supporting elements being the side walls made in the form of brackets with holders, the device having a bottom, and in the upper part of the casing between the front and a spacer in the form of a plate is mounted on the rear wall.

According to the utility model:

- at least, the front wall, side walls and the bottom have ventilation holes, each side wall having at least 3 ventilation holes, which are rectangular on one side wall and round on the other, and the front wall and bottom are made in the form of a grill;

- the holders have grooves for installing skewers or grills in them, which are semicircular on one of the side brackets and rectangular on the other;

- the rear wall is solid;

- The back wall has ventilation holes.

EFFECT: increased rigidity of a folding brazier design, is achieved as follows.

Rigidity is the ability of structural elements to resist deformation when exposed to external factors.

All body parts are made of sheet steel, which increases the rigidity of the entire collapsible structure (i.e., resistance to deformation). The side walls, made in the form of brackets with holders, are supporting elements, which increases the reliability of the structure also by increasing rigidity (stability of the barbecue). A spacer installed between the front and rear walls also increases the rigidity of the entire assembly brazier design.

The essence is illustrated in the figure, which shows the inventive device.

The device includes:

1 - back wall

2 - front wall

3 and 4 - side brackets,

5 - bottom

6 - spacer

7 - ventilation holes,

8 - holders of side brackets with grooves.

The device operates as follows.

Assembly: the bottom 5 with hooks (not shown) is inserted into the rear and front walls 1 and 2, from above the elements 1 and 2 are fastened with a spacer 6, then the assembled structure is installed in the bracket 3 on one side and 4 on the other side.

Biofuel (charcoal, firewood, fuel pellets, briquettes) is loaded into a rectangular case, doused with a special fluid for ignition and ignited. The location of the ventilation holes 7 on the elements 1, 2, 3, 4, 5 provides an air flow for quick kindling, the upper part of the product works like a pipe to provide air traction. This design solution ensures optimal use of fuel, the process of frying products can be continuous, since fuel can be added from above. Products in the rack or on skewers must be placed on the bracket holders 3 and 4 on the side of the heat source. To regulate the degree of frying of products, several grooves are provided at different distances from the front wall. The spacer 6 is installed on top, provides structural rigidity, and also allows you to install a container of water on top for heating or boiling.

Ventilation openings located in the side brackets, bottom, front and rear walls are selected experimentally to minimize the effects of thermal deformation on the device, which also increases the reliability and service life of the device. In addition, the location and shape of the holders of the side brackets and grooves on the holders ensure the rotation of the skewers and the uniformity of processing, which improves the quality of the product.

The location of the skewers or lattice with products on the side of the heat source ensures that the released fat flows down, without getting on fire and, accordingly, without burning oil. The distance to the heat source is adjusted by moving the skewers to different grooves in the side brackets. High quality cooking is achieved through uniform heat treatment, which ensures the absence of polyaromatic hydrocarbons, carcinogens, causing the formation of cancer cells in the human body. The design is collapsible, made of sheet material, for transportation it is packaged in a flat container, which makes it possible to use the product for hiking and outdoor recreation.

The design of the fuel box provides an optimal combustion process, allows you to report fuel from above, the cooking process is continuous.

The simplicity of the design allows you to assemble the barbecue in the field and cook kebabs even for a person without experience, since the process is fully controlled by selecting the distance to the heat source. EFFECT: increased reliability of a folding brazier during repeated use with ensuring high quality of product preparation.
