[0002] Smoke is usually regarded as waste that needs to be treated, but after proper treatment and transformation, it can also be used in many fields such as agriculture, materials and food. In agricultural production, moderate wood burning smoke can help prevent and control pests and diseases to a certain extent. In the traditional leather tanning process, wood burning smoke is sometimes used to assist the tanning process. Some components in the smoke can react with the protein in the leather to help the leather better shape and increase softness, and may also give the leather a special color and texture. When smoking food, using wood burning smoke to smoke meat, fish, soy products and other foods is a traditional and widely used processing method. Phenols, alcohols, carbonyl compounds and other components in the smoke will adhere to the surface of the food, not only adding a unique smoky flavor to the food, but also having a certain antiseptic effect, which can extend the shelf life of the food.

[0003] The smoke from burning wood usually contains sparks and some incompletely burned wood chips, or the smoke produced at different stages of combustion is different, which makes the smoke concentration uneven. In this way, whether it is used for tanning leather or smoking food, the effect of the obtained product is not ideal. Summary of the invention

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] refer to Figure 1 to Figure 11 The first aspect of the present invention protects a smoke dispersion device, which includes a smoke storage component 1 and a dispersion component 3 connected in a vertical direction, and a power component 2 is provided in the smoke storage component 1.

[0020] The product to be processed is placed in the smoke storage component 1. The product to be processed can be any item that needs smoke treatment, such as leather products, sausages, fish, and bean products.

[0021] A filter and a disperser are provided in the dispersion component 3 for filtering and dispersing the smoke. A stirring member is also provided in the dispersion component 3 for stirring the smoke. Among them, the filter is arranged at the bottom of the dispersion component 3, so that large impurities can be intercepted as early as possible. The positions of the disperser and the stirring member can be set at will. Preferably, the disperser is arranged between the filter and the stirring member. After the smoke is dispersed by the disperser, the temperature can be significantly reduced, many sparks will naturally go out, and large pieces of wood will find it difficult to pass through the disperser. The disperser also plays a role of secondary filtration to a certain extent. A stirring member is arranged above the disperser to provide a bottom cover to crush and intercept individual large impurities.

[0022] The power component 2 can pump the smoke in the dispersion component 3 into the smoke storage component 1; or the power component 2 can circulate the smoke in the smoke storage component 1. The power component 2 works in two stages. The first stage is to first pump the smoke from the outside into the dispersion component 3, and then pump the smoke into the smoke storage component 1. The second stage is to circulate the smoke in the smoke storage component 1 so that the concentration of the smoke can act on the product to be processed as evenly as possible.

[0023] The present invention sets the smoke storage component 1 and the dispersion component 3 separately, so that the smoke passes through the dispersion component 3 before entering the smoke storage component 1, so that the large impurities such as sparks and incompletely burned wood chips in the smoke can be trapped in the dispersion component 3 as much as possible, preventing the products to be processed from being damaged. By setting the filter, large impurities can be directly intercepted to prevent large impurities from entering the smoke storage component 1. By setting the dispersion component, the smoke can be preliminarily dispersed to make the concentration of the smoke uniform. By setting the stirring component, the smoke can be further dispersed. At the same time, the stirring component can also crush the large impurities that may remain to a certain extent, further preventing the large impurities from affecting the products to be processed. By setting the power component 2, power can be provided to enable the smoke below to enter the smoke storage component 1. In addition, the power component 2 circulates the smoke in the smoke storage component 1, and the circulation process can also evenly treat the smoke, so that the smoke concentration in the smoke storage component 1 is as consistent as possible.

[0024] refer to Figure 2 , Fig. 9 In a specific embodiment, the dispersion component 3 includes a second shell 31, a bottom hole 311 is provided on the bottom plate of the second shell 31, and the filter element is the bottom plate. The shape of the second shell 31 can be any shape such as cylindrical, cubic or conical. The second shell 31 in this embodiment is formed by a combination of cylindrical and conical shells. The conical shell is arranged above the cylindrical shell. The number of the bottom holes 311 is multiple. According to actual needs, a commercially available check valve can be provided at the top air outlet position of the second shell 31 to allow smoke to flow into the smoke storage component 1 in a unidirectional manner. A solenoid valve can also be provided at the top air outlet position of the second shell 31. Preferably, it is a solenoid valve that can be controlled to open or close.

[0025] An orifice plate group is disposed in the second shell 31 , and the orifice plate group is composed of a plurality of orifice plates 33 stacked in a vertical direction; the dispersion member is the orifice plate group.

[0026] In this embodiment, by setting the bottom hole 311, the external smoke needs to be filtered through the bottom hole 311 first, and large impurities are removed as much as possible before entering the second shell 31. The filtering through the bottom hole 311 can make the smoke entering the second shell 31 basically free of large impurities. By setting the orifice plate group. The smoke will be dispersed and mixed after passing through the orifice plate 33, so that the concentration of the smoke can be as uniform as possible. The smoke passes through the multi-layer orifice plate 33, which can make the smoke dispersed and mixed multiple times, and the concentration of the smoke is as consistent as possible. At the same time, some large impurities can also be intercepted by the multi-layer orifice plate 33, further preventing large impurities from entering the smoke storage component 1.

[0027] refer to Figure 2 or Fig.11 In a specific embodiment, the orifice plate 33 is formed by arranging a plurality of cone members 331 in a horizontal direction. The cone members 331 are cones. The top ends of the cone members 331 face the bottom plate, and plate holes 332 are formed between the plurality of adjacent cone members 331. The shape of the orifice plate 33 is set according to the shape of the second shell 31. The orifice plate 33 in this embodiment is circular, and a plurality of cone members 331 are arranged to form a flat plate, and then the flat plate is cut into a circle as the orifice plate 33. There will be a gap at the edge of the orifice plate 33. The orifice plate 33 has a complete plate hole 332 at a position away from the edge. Adjacent orifice plates 33 are staggered, and the cone members 331 on one orifice plate 33 correspond to the plate holes 332 on another adjacent orifice plate 33.

[0028] In this embodiment, a cone 331 is provided, and the top of the cone 331 faces the bottom plate. When the flue gas contacts the top of the cone 331, a high pressure point will be formed at the top, and then the flue gas will flow along the surface of the cone 331 to the bottom of the cone 331. Since the surface of the cone 331 is a curved surface, the gas will constantly change direction during the flow, and the flow velocity is relatively slow near the surface, and the farther away from the surface, the faster the flow velocity, forming a boundary layer. In the boundary layer, the flue gas is greatly affected by the viscosity force, and there will be a certain velocity gradient. After the flue gas bypasses the cone 331, a low pressure area will be formed behind the cone 331, and the flue gas will converge to this low pressure area from both sides of the cone 331 to form a wake. The flue gas flow in the wake is relatively turbulent, and vortices and other phenomena may occur. In this way, the flue gas can be fully mixed. Through the staggered orifice plates 33, the mixing effect of the cone 331 can be further exerted multiple times to improve the mixing effect.

[0029] refer to Fig. 9 In a specific embodiment, a bracket 32 ​​is provided in the second housing 31, and the center of the bracket 32 ​​is sleeved on the outside of the stirring paddle 34, and the stirring paddle 34 can rotate; the stirring member is the stirring paddle 34. The bracket 32 ​​is formed by the cross bars, and the cross position is sleeved on the outside of the stirring paddle 34. The friction between the stirring paddle 34 and the cross position is small, which is conducive to the rotation of the stirring paddle 34.

[0030] In this embodiment, the stirring paddle 34 has three functions. The first function is to mix the smoke passing through the orifice plate group to make the concentration and temperature of the smoke consistent, which is conducive to the processing of the product to be processed. The second function is to improve the fluid distribution, avoid problems such as dead corners or excessive local vortex in the second shell 31, and make the flow of smoke smoother. The third function is to break up the large impurities that may remain in the smoke, so that the smoke can smoothly enter the smoke storage component 1.

[0031] refer to Fig.10 In a specific embodiment, the stirring paddle 34 includes a paddle rod 341, and a spiral blade 342 is provided on the side of the paddle rod 341; the airflow passing through the spiral blade 342 can cause the spiral blade 342 to drive the paddle rod 341 to rotate.

[0032] The spiral blade 342 of this embodiment has two functions. The first function is that the smoke moves upward from the bottom and can drive the spiral blade 342 to rotate, so that the stirring paddle 34 can stir without an additional power source. The second function is that the rotation of the spiral blade 342 will generate local shear force and turbulence, which can disperse the smoke and enhance the stirring effect.

[0033] refer to Figure 2 and Figure 5 In a specific embodiment, the cigarette storage assembly 1 includes a first shell 11 having an interlayer, and a wall hole 111 is provided on the inner wall of the first shell 11. The first shell 11 can be a shell of any shape. In this embodiment, a hollow cylindrical shell is selected. The side and bottom surfaces of the first shell 11 are provided with an interlayer, and the interlayer on the side surface is connected to the interlayer on the bottom surface.

[0034] A central tube 13 is disposed in the first shell 11, and a plurality of tube holes 131 are disposed on the side wall of the central tube 13. The axis of the central tube 13 coincides with the axis of the first shell 11. The top end of the central tube 13 is closed and the bottom end is open.

[0035] A power assembly 2 is provided in the interlayer, and the power assembly 2 is connected to the central tube 13. When the smoke circulates, the power assembly 2 can pump the smoke in the central tube 13 into the interlayer.

[0036] In this embodiment, when the power assembly 2 is working, the smoke in the interlayer can enter the inner layer of the first shell 11 through the wall hole 111, and then enter the central tube 13 through the tube hole 131. The smoke in the central tube 13 then returns to the interlayer through the power assembly 2, thus realizing the circulation of the smoke. By providing the interlayer, the wall hole 111 and the tube hole 131, the smoke is continuously dispersed and mixed, the concentration and temperature of the smoke can be kept consistent, and the flowing smoke can also effectively process the product to be processed.

[0037] refer to Figure 2 , Figure 5 and Figure 7 In a specific embodiment, a protruding rod 15 is provided on the side wall of the central tube 13, the bottom of the protruding rod 15 is rotatably connected to the blade wheel 14, and a hook 16 is provided at the bottom of the blade wheel 14. The blade wheel 14 and the protruding rod 15 can be connected through a bearing. The blade wheel 14 includes a cylinder, and a plurality of plates are connected to the side wall of the cylinder.

[0038] In this embodiment, by providing the blade wheel 14 and the hook 16, the product to be processed can be hung on the hook 16. The smoke circulates in the first housing 11, which can drive the blade wheel 14 to rotate to a certain extent, and then the blade wheel 14 drives the product to be processed to rotate. The product to be processed can be evenly contacted with the smoke and evenly processed. Taking smoked sausages as an example, the blade wheel 14 drives the sausages to rotate, which can make the sausages fully contact with the smoke and improve the smoking effect. At the same time, the color of the sausages can be uniform.

[0039] refer to Figure 5~Figure 7 In a specific embodiment, a plurality of tube holes 131 are spirally distributed on the central tube 13. The extension rod 15 is correspondingly arranged above the tube hole 131. The wall hole 111 is arranged obliquely, and the angle between the axis of the wall hole 111 and the inner side wall of the first shell 11 is an acute angle. An ultraviolet lamp 12 is arranged on the inner side of the inner side wall of the first shell 11.

[0040] In this embodiment, the tube holes 131 and the extension rod 15 are arranged in a spiral ascending manner, so that the extension rod 15 is also distributed in a spiral ascending manner. This distribution has two functions. The first function is to enable the products to be processed to be staggered in both the vertical and horizontal directions so that each product to be processed can be fully exposed to the smoke. The second function is to prevent the products to be processed from affecting each other. Taking sausages as an example, during the smoking process of the sausages, oil will seep out of the surface, and under the action of gravity and the rotation of the blade wheel 14, the oil will drip below. The arrangement method of this embodiment can prevent oil from dripping on the sausages below, thereby avoiding affecting the smoking effect.

[0041] refer to Figure 5 By setting the wall hole 111 at an angle, the axis of the wall hole 111 is tangent to the outer periphery of the impeller 14. In this way, the smoke in the interlayer passes through the inclined wall hole 111, which is conducive to pushing the impeller 14, so that the impeller 14 can drive the product to be processed to rotate. In addition, the wall hole 111 is set at an angle, and the path of the smoke from the wall hole 111 to the tube hole 131 is a spiral path, which increases the residence time of the smoke inside the inner layer of the first shell 11.

[0042] refer to Figure 6 , multiple ultraviolet lamps 12 are arranged at intervals, and each ultraviolet lamp 12 is arranged in a vertical direction. By arranging the ultraviolet lamp 12, the treatment effect on the product is improved.

[0043] In the leather tanning process, ultraviolet rays can provide energy to stimulate the tanning agent molecules to react with the active groups in the leather collagen fiber molecules, promoting the formation of more cross-linked bonds between them. For example, when using aldehyde tanning agents, ultraviolet rays can cause the aldehyde groups to react with the amino groups and other groups in the collagen fibers more quickly to form a stable cross-linked structure, thereby accelerating the tanning process and shortening the tanning time. In addition, ultraviolet rays can act as a catalyst to reduce the activation energy of the tanning reaction. Reactions that originally required higher temperatures or longer times can now proceed quickly under relatively mild conditions. For example, in the vegetable tanning process, ultraviolet rays can promote better bonding between the tannin molecules in the vegetable tanning agent and the collagen fibers, improving tanning efficiency.

[0044] In the food smoking process, take sausage as an example. Ultraviolet irradiation can provide energy to promote the Maillard reaction between proteins, amino acids and sugars in sausages. The Maillard reaction is an important way to produce the unique flavor and aroma of smoked sausages. It can generate a variety of compounds with special aromas, such as pyrazines, furans, pyridines, etc., which make the sausages have a strong meaty aroma, roasted aroma and smoky aroma, enriching the flavor level of the sausages. Ultraviolet rays can also remove some polycyclic aromatic hydrocarbons. During the smoking process, due to incomplete combustion of wood and other reasons, some harmful polycyclic aromatic hydrocarbons, such as benzopyrene, may be adsorbed on the surface of sausages. Ultraviolet rays can trigger photochemical reactions of polycyclic aromatic hydrocarbons, change their structures, partially decompose or convert them into other relatively harmless substances, reduce the content of polycyclic aromatic hydrocarbons in sausages, and improve the safety of sausages.

[0045] refer to Figure 2~Figure 4 In a specific embodiment, the power assembly 2 includes a vacuum pump 21, which is arranged in the interlayer and communicated with the bottom end of the central tube 13. A one-way valve 23 is provided at the bottom end of the vacuum pump 21. The side wall of the vacuum pump 21 is connected to one end of an exhaust pipe 22, and the other end of the exhaust pipe 22 is an exhaust end, which is arranged in the air outside the first housing 11. A ball valve switch 24 is provided at the exhaust end.

[0046] In the first stage, the ball valve switch 24 is opened, the vacuum pump 21 is working, and the opening pressure of the one-way valve 23 is slightly higher than the normal pressure, so that the gas in the central tube 13 is discharged through the exhaust pipe 22. After a period of time, the external smoke passes through the dispersion component 3 and enters the smoke storage component 1. When the smoke concentration in the smoke storage component 1 is high, the ball valve switch 24 is closed. The smoke circulates inside the smoke storage component 1.

[0047] The second aspect of the present invention protects the use of any of the above-mentioned smoke dispersion devices in smoked products. The smoke dispersion device in the present invention has the functions of filtering and dispersing smoke and promoting food smoking, thereby ensuring the smoking effect of food.

[0048] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
