Description

FIELD OF THE INVENTION

The invention relates to the preparation of products: meat, poultry, fish when frying on charcoal or other sources of thermal radiation.

State of the art

In ordinary kitchen conditions, in the process of preparing foods, it is often necessary to change the temperature of heating the dishes and / or the product. This is dictated by the need to comply with the technological process of preparing certain dishes. And since in nature (whether it was a picnic, fishing or hunting) there was no such possibility yet, the dishes remained habitually simple: skewers on skewers, meat or fish cooked on a grill, well, and fish soup in a pot. Dishes are known to all of us, familiar and, of course, very tasty.

However, in order to cook in nature not only barbecue on skewers, but, say, pilaf in a cauldron or fry freshly caught fish in a pan right on the beach, or quickly and efficiently prepare your favorite sauce, etc. etc., for this is not enough habitual brazier, you need something else, and even with a smooth adjustment of temperature.

A known method of heat treatment of food by generating a radiation stream in the infrared spectrum and directing this stream to the processed product. This method is carried out in a furnace containing a housing, radiation sources in the IR spectral region, placed above and below the processed product, a stand for placing the product made of a material transparent to radiant energy [1].

The disadvantage of this method is that the irradiation of food occurs in the range from 1 to 1.4 microns, which contributes only to the heating of food, that is, food can only be heated, not cooked.

Closest to the proposed method is a method of frying kebab, including placing pieces of pre-prepared meat over burning and smoldering coals. Pieces of meat are placed and held between two rod frames evenly spaced from each other, which, in turn, are set at the same distance above the surface of the coal [2].

The disadvantage of the prototype method is the inability to adjust the temperature and control the process of cooking products.

Closest to the proposed device for the preparation of products is a collapsible barbecue, including side walls with internal flanges, end walls, bottom and legs, made from a corner, as well as clamps. The legs of the proposed device are rigidly, for example, by spot welding, connected to the end walls and detachably by means of clamps to the side walls, while the side walls are made with internal flanging of the upper and lower edges, the end walls are equipped with a similar flanging, but the flanging of the upper edge is made outward, the bottom made of at least two flat strips with internal flanges along the length that are installed on the flanges of the end walls with the possibility of entering under the lower flanges of the side s walls, wherein the total width of the bottom of the elements smaller than the width of the end walls.

The disadvantage of the prototype device is the complexity of the design and small functionality.

The objective of the invention is the expansion of functionality, increase reliability.

In FIG. 1 shows the design of the proposed device for the preparation of products, consisting of side walls 7, which form the frame of the device and on which, to provide additional rigidity, the metal is bent - 1 and cut 2 to accommodate skewers or knitting needles. The side walls 7 of the device are interconnected by a hinge 3. A part of the hinges is made detachable 4. The legs 5 of the device are made in the form of a corner. Under the device, a container of water 19 is installed, having dimensions larger than the dimensions of the device. In two opposite walls of the device, openings - 20 are made, closed with doors - 21.

In FIG. 2 shows the construction of fixing the legs to the side walls 7. The legs 5, made in the form of a corner, are fixed with a L-shaped gripper, which with its vertical shelf - 6 captures the frame of the device 7 from the bottom in the hinge region, by means of a nut - 8 presses it to the leg and securely fixes. Between the leg and the nut there is a forming gasket - 9.

Figure 3 presents the design of the lever lift - 10, consisting of one movable and one fixed rods and two upper rods and a movable lattice 11. The fixed lower rod is mounted in the holes 12, and the second movable rod is fixed in the grooves 13. On the two lower rods closer thrust washers - 14 are rigidly fixed to the ends. After assembly, they abut against the inner surface of the barbecue wall.

In FIG. Figure 4 shows the mechanism for moving the lever lift, carried out using a screw - 15, which, when assembling the device, is inserted into the groove - 16 and fixed with a clamp - 17. To protect the screw pair from temperature and from pollution from above, screw on the screw with a latch-clamp (not shown shown) a removable visor plate is installed - 18.

The implementation of the invention

The proposed method is carried out using a device for the preparation of products performed detachable-folding, consisting of side walls 7, forming a frame, and legs. The frame and legs are made of thin metal. In the upper and lower parts of the side walls 7 of the device, to ensure additional rigidity, edges 1 are bent 180 °. This design of the device allows to reduce the total weight while maintaining all consumer properties, and also prevents critical warping of the side walls after the completion of the heating / cooling cycle. The side walls of the device are interconnected pivotally - 3, thereby forming a strong frame. To ensure the “collapsible” function, one or several hinges are made detachable - 4, the central axis of the hinge for disassembling the connection is removed, and after assembly is inserted back. The legs 5 of the device are made in the form of a corner, on each shelf of which along the entire length there are edges 1, bent 180 ° to provide additional rigidity. The upper end of each leg 5 is wound behind the upper limb of the side wall, which provides not only a clear and reliable fixation of the upper part of the frame to the leg, but also a reliable perception of the entire weight load of the device along with dishes and products (the weight load is distributed vertically downward on the upper ends of the legs) . The lower part of the frame is fixed to the leg 5 (Fig. 2, section A-A), provides a L-shaped grip, which captures the frame of the device 7 from below in the hinge region with its vertical shelf 6, presses it against the leg 5 by means of a nut 8 and fixes it securely. Between the leg 5 and the nut 8, a forming gasket 9 is made of thicker metal (1.5 mm or more). The gasket 9 is molded, like the leg, in the form of a corner with an internal angle of 90 ° and aims to form right angles at the frame of the device, because the leg itself is made of thin (0.3-1.0 mm) metal and does not have its own sufficient rigidity to perform this task. To smoothly change the cooking temperature of the products, the device has a lever elevator 10. On the upper ends of the elevator levers, fastened together by two upper rods, or on these rods themselves, a movable grill 11. The two lower rods connecting the lower ends of the levers are made longer than top because they must “penetrate” the side walls of the device, thereby providing support to the lift. The fixed lower rod with its ends passes through the holes 12 in the opposite walls of the device, forming a hinge. The movable lower rod with its ends passes through the grooves 13 in the opposite side walls and has the ability to move within the groove, approaching or moving away from the stationary lower rod.

On both lower rods, closer to the ends, thrust washers 14 are rigidly fixed. After assembly, they abut against the inner surface of the device wall. Thanks to this, the device retains a rectangular shape in plan. This further enhances the rigidity and reliability of the structure.

The temperature adjustment process is as follows. When moving the movable lower rod to the side of the fixed lower rod, both upper rods will rise upwards with the movable grill installed on them 11. The movable grill, together with burning coals or other fuel, rises upward and approaches the heating object - the heating increases. The decrease in heating is achieved by the reverse sequence of actions: the distance between the lower rods increases, the movable lattice goes down, the heating decreases. Moving the movable rod of the lever hoist is carried out using a screw 15, which when assembling the device is inserted into the groove 16 and secured with a latch 17. To protect the screw from temperature and pollution from above, a removable latch is installed on the screw using a latch-clamp (not shown) visor 18.

To ensure the fire safety of the device, a container of water 19 is installed under it (for example, a rectangular tray, larger in plan than the dimensions of the device). As a result, the combustion products (hot ash, burning small coals, etc.) falling down go out in the water. Thus, the areas of use of the device are expanded, i.e. not only in specially prepared areas ensuring the safe use of open fire, but also in places where the use of open fire was prohibited or not considered in principle, for example, on a lawn, on a wooden sidewalk, on a table, etc. Additional device stability is also provided:

installed by the legs inside the tray, it is no longer supported by four points, but by a plane equal to or larger than the dimensions of the device.

In two opposite side walls of the device, openings 20 are made, which are closed by doors 21. Thanks to this design, the length limit of the used firewood disappears. Those. there is no need to cut or chop long firewood into small sizes. It is enough, having opened the doors in the opposite walls of the device, to place long firewood in the firebox so that they gradually burn out in half. In the future, shortened firewood should also be used for its intended purpose. Or, having opened only one door, place long firewood at one end in the furnace and move them inward as they burn.
