[0036] The loosening device is set up to replace manual loosening of tobacco leaves, thus improving efficiency.

[0037] Example 2

[0038] like Figure 1-6 As shown, this embodiment is a detailed introduction of the loose device:

[0039] A loosening device comprises a shell 1, a large rake nail roller 4 rotatably connected to the shell 1 and used for loosening tobacco blocks, a first driving device 5 for driving the large rake nail roller 4 to rotate, a small rake nail roller 2 rotatably connected to the shell 1 and used for loosening tobacco blocks, and a second driving device 3 for driving the small rake nail roller 2 to rotate; the large rake nail roller 4 rotates in opposite directions to the small rake nail roller 2.

[0040] The large rake nail roller 4 is provided with n large rake nail groups 41, and the n large rake nail groups 41 are arranged at equal intervals along the length direction of the large rake nail roller 4; the nails in each large rake nail group 41 are evenly distributed along the circumferential direction.

[0041] The small rake nail roller 2 is provided with n-1 small rake nail groups 21, which are arranged axially along the small rake nail roller 2, with the spacing between adjacent small rake nail groups 21 being equal, and the nails in each small rake nail group 21 are evenly distributed along the circumferential direction.

[0042] Looking vertically downward, the small rake nail group 21 is arranged in the middle of the adjacent large rake nail group 41.

[0043] The first driving device 5 has the same structure as the second driving device 3 . The first driving device 5 includes a reducer and a motor. The reducer is drivingly connected to the large rake roller 4 .

[0044] The shell 1 is provided with a funnel 12, and the funnel 12 is used to receive tobacco leaf blocks.

[0045] A dust removal device is provided on the side wall of the shell 1 near the bottom, and the dust removal device includes a dust hood 6 installed in the shell 1, a dust removal pipe 62 fixedly connected to the dust hood 6, and a dust dispersion pipe 61 fixedly connected to the dust hood 6; the dust hood 6 is similar in shape to the range hood of a range hood, with one end open, and the top surface of the dust hood 6 is tilted downward to prevent tobacco leaf blocks from remaining on the top surface of the dust hood 6.

[0046] like Figure 6 The dust removal pipe 62 is provided with a long strip of dust removal holes, and the dust removal holes are facing the open end of the dust removal cover 6; the dust removal pipe 62 is connected to the dust removal fan, and the dust dispersion pipe 61 is provided with an air outlet slot, and the dust dispersion pipe 61 is connected to the blower; the air outlet direction of the air outlet slot is perpendicular to the air inlet direction of the dust removal hole, so as to break up the dust and avoid clogging of the dust removal pipe 62.

It is found during use that when the rotation speed of the large rake nail group 41 is 20% greater than that of the small rake nail group 21, the crushing efficiency is highest.

[0049] Example 3

[0050] This example is a detailed explanation of the gravity impurity removal device.

[0051] like Figure 7 , 8As shown, the arrows in the figure indicate the direction of wind flow when the tobacco leaves are selected by air. The gravity impurity removal device includes a fan 7. The fan 7 introduces wind into the tobacco leaf inlet through a pipeline, and the wind blows the light tobacco leaves upward. During the floating process of the light tobacco leaves, a camera is provided to take pictures of the tobacco leaves passing through and transmit them to the controller, which is compared with the standard tobacco leaves in the controller. Qualified tobacco leaves continue to float under the action of wind, and unqualified tobacco leaves are blown to the debris outlet through a high-pressure compressed air nozzle. A spectrum detection process is added behind the camera to perform spectrum detection on the tobacco leaves passing through. A standard tobacco leaf spectrum is provided in the controller, and the collected tobacco leaf spectrum is compared with the standard. Unqualified tobacco leaves are blown away by the high-pressure air and fall at the debris outlet. The tobacco leaves that have been detected twice are judged to be qualified and enter the finished tobacco leaf outlet. The wind inlet of the fan is connected to the tobacco leaf outlet, and a part of the pressurized air is introduced into the fan 7, so that the air can be reused to form a closed loop of wind power, which effectively reduces the power of the fan.

[0052] The heavier, unloose tobacco blocks move downward under the action of gravity, are discharged through the tobacco block outlet 8, and are finally sent to the loosening device for further loosening. A wind force regulating device 9 is provided before the fan 7 enters the tobacco inlet to adjust the wind force according to the type and weight of the tobacco leaves.

[0053] Example 4

[0054] The method of loosening the agglomerated smoke in this embodiment is to first heat the agglomerated smoke with microwaves and then loosen the agglomerated smoke through the loosening device of Example 2. That is, in the method, a microwave heating device is installed above the loosening device to rapidly increase the temperature of the smoke blocks through microwave heating, thereby facilitating sufficient mechanical loosening.

[0055] After the agglomerated smoke is collected by the gravity impurity removal device, it is transported to the microwave heating process by a conveyor belt, heated, and then loosened;

[0056] Since microwaves are a type of very high-frequency electromagnetic wave, they can form a high-frequency alternating magnetic field that causes polar molecules to absorb energy and heat up. They have the characteristics of strong penetration, small thermal inertia, strong selectivity, fast speed, and good effect. Accompanied by the non-thermal mechanical force, they can inactivate organisms, disrupt cell membrane function, dehydrate cells, and coagulate proteins, thereby fundamentally achieving the purpose of killing insects.

[0057] The agglomerated tobacco is sent into the microwave heating loosening machine through a belt. When the tobacco block enters the cavity, the anti-flow door is closed, and then the microwave generator emits microwaves to heat it. The microwave transmission belt moves slowly. When the tobacco block approaches the cavity outlet, the microwave emission stops. Then the transmission belt runs quickly to bring the microwave-heated tobacco block out of the cavity, and the discharge transmission belt sends the tobacco block to the loosening bag feeding and rehumidification process.

[0058] (1) The loosening effect of microwave heating is better than that of slicing. Microwaves can heat the inside and outside of the material at the same time. When the tobacco slice is irradiated by microwaves, the temperature gradient and moisture pressure inside the tobacco slice diffuse from the center to the outside, causing the moisture in the tobacco slice to quickly migrate to the surface or evaporate. On the one hand, this effect causes irregular changes on the surface of the tobacco slice; on the other hand, the increase in temperature helps to reduce the viscosity of the liquid on the surface of the tobacco slice, weakening the adhesion between the slices, and the tobacco slice expands due to heat, so the loosening rate is high and the loosening effect is good.

[0059] (2) Microwave heating loosening can improve the structure of tobacco slices, increase the rate of large and medium slices, and reduce the rate of fragments, which is beneficial to reducing consumption and improving the quality of cigarettes.

[0060] (3) Microwave heating loosening can better ensure that the material is uniform and stable before entering the moisture conditioning cylinder, which is conducive to fine processing.

[0061] (4) Microwave heating is safe and harmless, does not produce "three wastes", does not pollute tobacco leaves, and has an insecticidal and sterilization effect of 100%.

[0063] (5) After the tobacco leaves are loosened by microwave heating, there are obvious improvements in smoke concentration, impurities, and oral comfort, which also improves the sensory quality of lower-grade tobacco leaves.

[0064] (6) The application of microwave heating loosening technology to the tobacco strip making process is an innovation that can improve the quality of tobacco strip processing, simplify the processing equipment and shorten the process flow. However, the system is not yet perfect. There are still problems such as high local temperature of the tobacco package after processing and poor purity of the incoming materials. It needs to be further improved and perfected in future production practice, such as optimizing equipment parameters and adding metal detectors and smoke alarms before the tobacco strips enter the equipment.
