[0002] Smoking is a method of processing food using smoke from incomplete combustion of fuel, with the aim of changing the taste of the product, improving its quality and extending its shelf life. This cooking technique has a long history and is often used in combination with pickling, especially in the processing of fish and meat products. Smoking ovens use this method to smoke the desired meat products.

[0003] A smoking oven for producing and processing tea smoked hams disclosed in the publication number CN215836867U is retrieved, comprising a smoking oven body, a base, a bracket, a universal wheel, a smoke generating furnace, a combustion chamber door, a boiling chamber door, a steam pipe, a smoke pipe and a suction fan, wherein: the smoking oven body is arranged on one side of the upper surface of the base through the bracket; the universal wheel is arranged on the bottom surface of the base; the smoke generating furnace is arranged on the other side of the upper surface of the base; the combustion chamber door is arranged below the surface of the smoke generating furnace; the boiling chamber door is arranged above the surface of the smoke generating furnace. The setting of the smoke generating furnace of the utility model can maximize the tea flavor into the interior of the smoked hams when in use, and can make the tea evenly and thoroughly burn, effectively preventing the trouble of easy waste of heat during combustion, and facilitating market promotion and application.

[0004] The smoke generated during the smoking process still contains a large amount of heat after the meat food is smoked, and the smoke will be mixed with harmful substances such as carbon monoxide, carbon dioxide and particulate matter that pollute the air. The above technical solution directly discharges the smoke generated after combustion into the air, which will cause air pollution and waste the heat in the smoke. Moreover, if the heat is not reduced when it is directly discharged into the air, it will also cause damage to the environment. Utility Model Content

[0005] The utility model aims to provide a circulating flow energy-saving smokeless smoking oven to solve the problems that the smoke generated after combustion is discharged into the air, which will cause air pollution and waste the heat in the smoke, and directly discharge it into the air without reducing the heat, which will also cause damage to the environment.

[0006] The utility model provides the following technical solutions: a circulating flow energy-saving smokeless fumigation oven, comprising a fumigation oven main body, an outer side wall of the fumigation oven main body is hingedly connected with a sealing door, a lower bottom end of the fumigation oven main body is slidably connected with a combustion box for placing fuel, a plurality of placement racks for placing smoked objects are arranged inside the fumigation oven main body, a plurality of smoke holes for the passage of smoke are opened at the inner bottom end of the fumigation oven main body, and a circulation component for recycling smoke is arranged on the outer side wall of the fumigation oven main body.

[0008] As a preferred embodiment of the above technical solution, the circulation component includes a smoking device fixedly connected to the outer side wall of the smoke-roasting furnace body, the inlet and outlet ends of the smoking device are fixedly connected to a smoking pipe that communicates with the interior of the smoke-roasting furnace body, the output end of the smoking pipe is fixedly connected to a smoke guide pipe, the lower bottom end of the smoke guide pipe is fixedly connected to a smoke exhaust pipe, and a heat exchange box is fixedly connected to the outer side wall of the smoke-roasting furnace body at a position corresponding to the smoke guide pipe, and a filtering structure for treating smoke is provided on the outer side wall of the smoke-roasting furnace body below the heat exchange box.

[0009] By adopting the above scheme, when the smoke is located at the inner top of the smoke-roasting oven body due to the influence of air pressure, the smoker can be started so that the smoker can draw out the smoke and send it into the smoke guide pipe through the smoking pipe. Since the heat in the smoke is relatively high, the heat can be exchanged through the smoke guide pipe, thereby increasing the temperature of the liquid inside the heat exchange box to reduce the heat in the smoke. At this time, the smoke continues to move and will enter the filtering structure.

[0010] As a preferred embodiment of the above technical solution, the outer side walls of the heat exchange box are respectively fixedly connected with a water inlet pipe and a first drain pipe.

[0011] By adopting the above solution, when the liquid inside the heat exchange box reaches a certain temperature, it can be discharged through the first drain pipe, and new liquid can be discharged back into the heat exchange box through the water inlet pipe.

[0013] By adopting the above scheme, after the liquid inside the heat exchange box reaches a certain temperature, it will enter the water storage area through the first drain pipe for storage, while the flue gas enters the filtration area and is absorbed by the activated carbon plate to cause harmful gases. As the filtration proceeds layer by layer, the flue gas can be discharged through the smoke exhaust holes, and as the heated liquid enters the water storage area, the heat can be conducted. At this time, the temperature of the activated carbon plate increases, and the pore structure of the activated carbon plate increases, thereby being able to better absorb harmful substances in the flue gas.

[0014] As a preferred embodiment of the above technical solution, the outer wall of the processing box is hingedly connected with a sealed material replacement door, and the end of the smoke exhaust pipe is connected to the interior of the filter area.

[0015] By adopting the above scheme, the sealed material changing door can replace the activated carbon plate and prevent smoke from leaking from the gap of the material changing door.

[0016] As a preferred embodiment of the above technical solution, one end of the first drain pipe is communicated with the interior of the water storage area, and a second drain pipe is fixedly connected to the outer wall of the treatment box at a position corresponding to the water storage area.

[0017] By adopting the above scheme, when the liquid inside the water storage area needs to be used, it can be discharged through the second drain pipe, and the heated liquid can clean the inside of the smoke-roasting furnace body, and heat exchange through flue gas can achieve the purpose of energy saving and avoid waste.

[0018] As a preferred embodiment of the above technical solution, the outer walls of the water inlet pipe, the first drain pipe and the second drain pipe are all provided with control valves.

[0019] By adopting the above solution, the setting of the control valve can control the discharged medium to control its discharge amount.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In the utility model, a circulation component is provided. When in use, the smoke is sucked into the smoking pipe through the smoking device, and enters the filtering area through the smoke guide pipe and the smoke exhaust pipe to be filtered. In this process, since there is a large amount of heat energy in the smoke, in order to reduce the heat energy, after the smoke enters the smoke guide pipe and the heat exchange box, its temperature will be reduced by the water in the heat exchange box. When the temperature of the water reaches a certain level, it will enter the water storage area through the first drain pipe. At this time, the temperature of the water storage area rises and is transferred to the filtering area. After the activated carbon plate is heated, its pore structure will be more open, which can better absorb harmful substances in the smoke, and the heated water can be used to clean the inside of the smoker oven body after the smoking is completed.
