Description

Technical Field

[0001] The present invention relates to an industrial oven for cooking food, and in particular to a novel industrial microwave gas oven with double cooking chambers for fast cooking of food. Background Art

[0002] Various techniques for cooking food are well known.

[0003] Especially in some Middle Eastern and North African countries, it is common to cook meat, especially lamb, but also chicken and beef, which is then eaten with cereals such as rice.

[0004] Most common cooking methods (processes) involving cooking large cuts of meat require long cooking times, even hours, before the meat is cooked and ready for consumption.

[0005] Therefore, in addition to the fact that this type of food is consumed in large quantities, it is often difficult to meet demand in terms of quantity and preparation time.

[0006] Furthermore, because it takes much longer to cook meat than it does to cook grains such as rice, it is often difficult to coordinate the preparation of these different types of food. Summary of the invention

[0007] The subject of the invention is a novel industrial microwave gas cooker with double cooking chambers.

[0008] The main purpose of the present invention is to reduce the cooking time of meat compared to the time required for cooking large pieces of meat, especially lamb, chicken or beef, as used to date.

[0009] Another object of the invention is to achieve a cooking method by which meat is cooked in a manner similar to traditional cooking methods in order to obtain a cooked product comparable in consistency and taste to those traditionally obtained with longer cooking times.

[0010] Another object of the present invention is to allow meat and cereals to be cooked simultaneously.

[0011] Another object of the present invention is to allow other foods (such as rice) to be cooked together with meat, using the juices produced by the meat during the cooking process to flavor the other foods.

[0012] These and other direct and supplementary objects are achieved by the novel industrial microwave gas cooker with double cooking chambers, the main components of which include:

[0013] - a box-type (box-shaped) structure, defining inside it a first cooking chamber or an upper cooking chamber and a second cooking chamber or a lower cooking chamber positioned below the upper cooking chamber, wherein the upper cooking chamber and the lower cooking chamber are connected to each other, and wherein the cooking chamber is provided with a wall consisting of double-layer plates with an air gap (air cavity) between the double-layer plates;

[0014] - at least one support (support) mounted in said upper cooking chamber, rotatable about a substantially vertical axis, said support being provided with at least one hook for suspending the product to be cooked in said upper cooking chamber;

[0015] - at least one gas burner located below said lower cooking chamber;

[0016] - at least one device suitable for emitting microwaves and located in said upper cooking chamber,

[0017] The food cooking method is carried out in the upper cooking chamber in a combined manner by the microwave device and by the gas burner.

[0018] In practice, the novel industrial oven advantageously comprises one or more fans installed in said lower cooking chamber and / or in said upper cooking chamber, so as to ensure the circulation of the hot air and to guarantee an even distribution of heat in both cooking chambers.

[0019] As mentioned above, the two cooking chambers are stacked and interconnected so that the heat generated by the gas burner can also reach the upper cooking chamber, and the juice and smell (aroma) generated by the food placed in the upper cooking chamber during cooking can fall into the lower cooking chamber.

[0020] The lower cooking chamber preferably accommodates at least one tray or container suitable for holding other food to be cooked, such as cereals, conveniently rice, and for collecting the juices falling from the upper cooking chamber.

[0021] The combustion process takes place in a compartment located below the lower cooking chamber and communicating with an air gap in the wall of the cooking chamber.

[0022] According to the invention, in order to extract the combustion fumes, the novel oven is provided with at least one smoke extraction duct which communicates with an air gap in the wall of the cooking chamber.

[0023] The upper cooking chamber and the lower cooking chamber are separated from each other by a partition (partition member) which allows air circulation between the two cooking chambers and also allows the penetration of juice and odor from the upper cooking chamber. For example, the partition member is a tray with holes or a mesh (mesh member).

[0024] The use of the novel industrial oven thus makes it possible to use the upper cooking chamber to cook pieces of meat suspended on the hooks of said at least one support. According to the invention, each of said hooks can advantageously further be rotated about its vertical axis.

[0025] Therefore, the meat placed in the upper cooking chamber is cooked by the dual effects of the gas burner (meaning as if it were placed in a common oven) and microwaves, thereby shortening the cooking time.

[0026] In addition, the novel stove can be used to cook other food placed in the lower cooking chamber, wherein the other food is cooked simultaneously with the meat placed in the upper cooking chamber.

[0027] For example, the other food placed in a container or tray located in the lower cooking chamber is cooked mainly by the heat generated by the gas burner, and the container or tray collects the juices produced by the cooked meat, which fall into it and are thereby mixed with the other food.

[0028] There are several advantages to using this new stove.

[0029] Cooking times are significantly reduced, especially when cooking meat, especially when cooking medium to large cuts of meat.

[0030] The new oven allows a combined cooking method to be performed, which gives meat a consistency and a taste similar to that obtainable by traditional cooking methods in a gas oven or electric grill.

[0031] The novel oven also enables other foods to be cooked simultaneously, for example and in particular foods used as a side dish to meat, such as rice, which is seasoned and cooked during the cooking process together with the juices produced by the meat itself.

[0032] The characteristics of the novel oven are highlighted in more detail in the following description, with reference to the accompanying drawings which are attached by way of non-limiting example. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The novel industrial furnace (1) comprises a box-type structure (10), wherein at least two cooking chambers (20, 30) are defined inside the box-type structure (10).

[0037] The box-type structure (10) comprises an outer frame (11) and a lower support element adapted to rest on the ground, the lower support element may be a rotating wheel (12) and / or a fixed wheel or fixed foot.

[0038] The frame (11) is provided with a front opening (13) and a front door (14) for closing the opening (13).

[0039] The box-type structure (10) has two cooking chambers (20, 30) inside, in particular a first upper cooking chamber (20) and a second lower cooking chamber (30) located below the upper cooking chamber (20).

[0040] The upper cooking chamber (20) and the lower cooking chamber (30) are connected to each other, and in particular they are separated by a partition (40), and the partition (40) allows at least gas and liquid to pass between the upper cooking chamber (20) and the lower cooking chamber (30) in any way.

[0041] For example, the partition (40) may be a perforated plate or a grid, the mesh of which is large enough to allow gas and liquid, and possibly even solid fragments of a certain size, to pass through it.

[0042] The cooking chamber (20, 30) is defined by a wall (60), and the wall (60) is formed by double-layer plates (61, 62), with an air gap (not shown) between the double-layer plates (61, 62).

[0043] At least one support (22) is provided in the upper cooking chamber (20), and the product to be cooked can be hung on the at least one support (22).

[0044] The support (22) is preferably mounted at the center of the top plate (23) of the upper cooking chamber (20) and rotates around a substantially vertical rotation axis (Z).

[0045] The support (22) preferably comprises a horizontally positioned planar disc or ring (221) and is provided with one or more hooks (222) on which the food to be cooked can be hung so that the food is suspended substantially in the center of the upper cooking chamber (20) and arranged vertically.

[0046] For example, the hooks (222) are evenly distributed on the support (22), for example distributed on a circumference whose center is located on the rotation axis (Z).

[0047] The hook (222) preferably rotates in turn around its own vertical axis (Z1), which in turn rotates relative to the planar disk or ring (221) of the support (22).

[0048] In this way, the outer surface of the suspended food is fully and evenly exposed to the heat source during the cooking process.

[0049] The support (22) is set in rotation by means of an electric motor (223), for example by a chain drive preferably mounted outside the box-type structure (10).

[0050] The lower cooking chamber (30) is adapted to receive at least one tray or container (not shown) for holding food to be cooked, such as cereals, conveniently rice.

[0051] The novel stove (1) comprises at least one gas burner (50), which is located below the lower cooking chamber (30), in particular in a compartment (51) below the lower cooking chamber (30) and is connected to an air gap in a wall (60) of the cooking chamber (20, 30).

[0052] In order to extract combustion smoke, the novel stove (1) is provided with at least one smoke extraction flue (52), which is connected to an air gap in the wall (60) of the cooking chamber (20, 30).

[0053] As mentioned above, the two cooking chambers (20, 30) are stacked together and communicated with each other so that the heat generated by the gas burner (50) can also reach the upper cooking chamber (20), and furthermore, the juice and odor generated by the food cooked in the upper cooking chamber can fall into the lower cooking chamber (30) through the partition (40) and be collected by the tray or container, in which the food contained therein is mixed with the above substances.

[0054] However, according to the present invention, the spacer (40) can be removed and replaced by a different type of spacer.

[0055] In order to ensure uniform distribution of heat in the cooking chambers (20, 30), the novel industrial oven (1) conveniently comprises one or more fans (70), which are installed, for example, in the lower cooking chamber (30) and are suitable for ensuring the circulation of hot air.

[0056] The fan (70) is operated by a corresponding electric motor (71), which is installed, for example, outside the box-type structure (10).

[0057] The novel oven (1) also comprises at least one device (80) suitable for emitting microwaves and located in the upper cooking chamber (20), which is mounted, for example, on the vertical wall (21), conveniently on the rear wall opposite to the front door (14).

[0058] A unit (81) comprising one or more microwave generators and respective cooling fans is for example mounted outside and behind the box-type structure (10).

[0059] Therefore, the food suspended in the upper cooking chamber (20) is cooked in a combined manner due to the action of the microwave device (80) and the heat generated by the gas burner (50).

[0060] On the contrary, the food contained in the lower cooking chamber (30) is cooked mainly due to the effect of the heat generated by the gas burner (50), and the tray or container collects the juice falling from the meat cooked in the upper cooking chamber.

[0061] Preferably, there is also a distribution board (90) for operating the new stove outside the box-type structure (10), which includes a gas burner ignition device (91), a switch (92), a control device, such as a touch screen (94), a possible and convenient warning light (93) and / or a display suitable for providing information related to the operation of the stove, including operating parameters and fault information, if any.

[0062] The above is an illustrative overview sufficient to enable those skilled in the art to implement the invention; therefore, in the practical application of the present invention, any variation that does not affect the essence of the innovative concept introduced herein is permitted.

[0063] Therefore, with reference to the above description and accompanying drawings, the following claims are made.
