[0018] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0019] This utility model embodiment provides a tobacco leaf crushing device. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 It mainly includes a pre-cutting component 3, a crushing component 4, a homogenizing component 5, and an emulsifying component 6.

[0020] In this embodiment, the tobacco leaf crushing device includes a housing 2, inside which a tobacco leaf moving chamber 1 is provided. The housing 2 is provided with an inlet 21 and an outlet 22. Tobacco leaves can enter the tobacco leaf moving chamber 1 through the inlet 21 and then exit the tobacco leaf crushing device through the outlet 22. The tobacco leaf moving chamber 1 is arranged sequentially along the moving direction of the tobacco leaves, including a pre-cutting component 3, a crushing component 4, a homogenizing component 5, and an emulsifying component 6. After the tobacco leaves enter the tobacco leaf crushing device through the inlet 21, they will first be initially crushed on the pre-cutting component 3, then undergo fiber dissociation on the crushing component 4, then undergo cell wall crushing on the homogenizing component 5, then undergo subcellular structure release on the emulsifying component 6, and finally be discharged from the outlet 22. This application operates on tobacco leaves by sequentially arranging a pre-cutting component 3, a crushing component 4, a homogenizing component 5, and an emulsifying component 6 within the outer casing 2 along the direction of tobacco leaf movement. Specific components can be selected for operation based on the characteristics of the tobacco leaf raw materials. The pre-cutting component 3, the crushing component 4, and the homogenizing component 5 enhance the mechanical shearing strength of the tobacco leaf crushing device on the tobacco leaf cell walls, thereby increasing the cell breakage rate and the retention rate of cell active ingredients.

[0021] In one possible implementation, the pre-cutting assembly 3 includes a feeding bin 31 and rollers 32. The feeding bin 31 is inverted conical in shape, with its first end connected to the feed inlet 21. Two rollers 32 are arranged side-by-side, with the second end of the feeding bin 31 positioned between the two rollers 32. The surface of each roller 32 is decorated with staggered trapezoidal raised patterns and is covered with a removable tungsten carbide wear-resistant liner. When the tobacco leaves move from the feeding bin 31 to between the two rollers 32, the pre-cutting assembly... Figure 1 As shown in the left and right directions for reference, the left roller 32 rotates clockwise and the right roller 32 rotates counterclockwise. The two rollers 32 squeeze the tobacco leaves to perform preliminary crushing.

[0022] Furthermore, the pre-cutting assembly 3 also includes a set of scrapers 33, which comprises multiple scrapers 33 arranged side-by-side below the roller 32, with the vertical direction being... Figure 1 In the vertical direction, the gap between the blade of scraper 33 and the roller surface is less than or equal to 20mm. By setting scraper 33, tobacco leaf fragments are avoided from adhering to the roller 32, thereby ensuring the cutting effect of roller 32.

[0023] In one embodiment, the crushing assembly 4 includes multiple crushing units arranged side-by-side along the tobacco leaf movement direction. Each crushing unit includes a cutter head 41 and a screen 42 corresponding to the cutter head 41. The screen 42 is arranged downstream of the cutter along the tobacco leaf movement direction. For example, a serrated cutter head 41, a first screen 42, a sawtooth cutter head 41, and a second screen 42 are arranged sequentially along the tobacco leaf movement direction. The serrated cutter head 41 and the sawtooth cutter head 41 are coaxially arranged and driven by a motor to rotate synchronously. The first screen 42 has an aperture of 10 mm, and the second screen 42 has an aperture of 3 mm.

[0024] Furthermore, the crushing assembly 4 also includes an airflow nozzle 43, which is arranged downstream of the crushing unit along the direction of tobacco leaf movement. The airflow nozzle 43 sprays air towards the screen 42. By setting the airflow nozzle 43, the tobacco leaves on the screen 42 are blown towards the cutter, which avoids the screen 42 from being blocked due to the accumulation of tobacco leaves, and at the same time ensures that all tobacco leaves can pass through the screen 42 at the same time to enter the next process.

[0025] In one possible implementation, the homogenizing component 5 includes a homogenizing rotor 51 and a homogenizing stator 52, wherein a grinding space 53 is provided within the homogenizing stator 52 along the height direction (i.e., Figure 1 (As shown in the up-down direction) A material inlet is provided on one side of the homogeneous stator 52 and the screen 42. The homogeneous rotor 51 is arranged in the grinding space 53. The inner wall of the homogeneous stator 52 and the outer wall of the homogeneous rotor 51 form a grinding chamber 54. When the tobacco leaves fall from the screen 42 into the grinding chamber 54, the homogeneous rotor 51 rotates. Under the action of the homogeneous rotor 51, the tobacco leaves are subjected to the frictional force between the homogeneous rotor 51 and the homogeneous stator 52, thereby grinding the tobacco leaves into a slurry. Specifically, the homogeneous rotor 51 is composed of 6 titanium alloy blades. The edges of the blades are provided with serrated protrusions. The distance between the titanium alloy blades and the homogeneous stator 52 is greater than 0.5 mm.

[0026] Furthermore, both the homogeneous rotor 51 and the homogeneous stator 52 are conical, so that the ground tobacco leaves will move to the next process under the action of gravity, saving energy consumption of the tobacco leaf crushing device.

[0027] Furthermore, a cleaning screen is arranged inside the discharge port. The surface of the cleaning screen is coated with polytetrafluoroethylene. When the homogenizing rotor 51 rotates, the homogenizing rotor 51 generates airflow on the cleaning screen to remove the residue on the cleaning screen.

[0028] In one embodiment, the emulsification component 6 includes a jet plate 63, a pressure control rod 64, a pressure sensor, and a pressure motor. The jet plate 63 is provided with a cavitation feed hole 61, a cavitation reaction hole 62, and a Y-shaped flow channel. The pressure control rod 64 abuts against the cavitation feed hole 61 and is connected to the pressure motor. The pressure motor drives the pressure control rod 64 to move, thereby adjusting the opening degree of the cavitation feed hole 61. The slurry generated in the homogenization component 5 moves in the Y-shaped flow channel of the jet plate 63. When the slurry converges in the jet plate 63, the high-pressure slurry after convergence is forced to pass through the cavitation reaction holes 62 evenly distributed on the plate surface. According to Bernoulli's principle, when the slurry passes through the cavitation reaction holes 62 at high speed, the local pressure will drop sharply. When it is lower than the saturated vapor pressure of the slurry, cavitation will occur, generating a large number of microbubbles. The microbubbles collapse instantly (implode) in the high-pressure zone behind the jet plate 63, releasing huge energy, thereby extracting the active ingredients in the tobacco leaves.

[0029] Furthermore, the emulsification component 6 also includes a pressure relief valve, which is arranged along the height direction on the side of the jet plate 63 away from the pressure control rod 64. When the pressure behind the jet plate 63 is too high, the pressure relief valve releases pressure.

[0030] In one embodiment, the tobacco leaf crushing device includes a liquid cooling pipe 7 arranged in the tobacco leaf moving chamber 1. Cold water passes through the liquid cooling pipe 7 and exchanges heat with the tobacco leaf crushing device, thereby reducing the temperature in the tobacco leaf moving chamber 1 and thus preventing the protein substances generated during tobacco leaf crushing from being deactivated by heat.

[0031] The working principle of the tobacco leaf crushing device of this application is as follows: tobacco leaves are fed into the feeding bin 31, and then fall into the scraper 33 group under the squeezing and cutting action of two rollers 32. The tobacco leaves are then cut into strips. The strips of tobacco leaves pass through the wolf tooth-shaped cutter disc 41, the first screen 42, the saw tooth-shaped cutter disc 41 and the second screen 42 in sequence for secondary crushing. The tobacco leaves that have undergone secondary crushing form a slurry under the interaction of the homogeneous rotor 51 and the homogeneous stator 52. The slurry then undergoes the cavitation reaction of the baffle plate to extract the active ingredients of the tobacco leaves.
