[0002] The baking of tobacco leaves is an important process in the cigarette production process, which determines the overall quality of tobacco leaves. At present, traditional tobacco leaf baking is carried out in a dedicated baking house through heating and ventilation measures, and the baking of tobacco leaves is achieved by adjusting the temperature and humidity of the baking house. The early baking process of tobacco has a great influence on the later preparation of tobacco. Only through effective baking can the appearance quality, chemical quality, physical quality and smoking quality of tobacco leaves be guaranteed.

[0029] The features and performance of the present utility model will be further described in detail below in conjunction with the embodiments.

[0030] Please refer to Figures 1-4 , a graphene intelligent baking test chamber, as Figure 1 and Figure 2 shown, includes a main box body 1, a heating chamber and a loading chamber are arranged in the main box body 1, an upper ventilation duct and a lower ventilation duct for ventilation are arranged between the heating chamber and the loading chamber; an air inlet facility and an air outlet facility are arranged above the heating chamber and the loading chamber; as Figure 4As shown, a graphene heating plate 16 for heating the cold air during its sinking process is provided inside the heating chamber compartment; as Figure 3 As shown, a visual camera 10 for observing the state of tobacco leaves is provided inside the tobacco loading chamber compartment, and a front observation window 3 and a side observation window 9 for observing the tobacco leaf baking process are provided on both sides of the tobacco loading chamber compartment.

The addition of the visual camera 10 enables better observation and control of the tobacco leaf baking process, facilitating the control of baking quality and the collection of baking data, and opening a new "green intelligent" baking mode.

[0031] Using the new material graphene heating plate 16 as the heating material, compared with the traditional heating tube, it has stable performance, simple construction, energy conservation and environmental protection, good heating uniformity, flexible heating temperature control, fast heating response speed, and high energy conversion rate. It can achieve safer, more environmentally friendly, and more economical green baking, and produce "low-carbon" tobacco leaves.

[0032] A negative pressure pump 12 and an air inlet pipe 11 are provided above the heating chamber compartment. A switch valve 12 is provided on the air inlet pipe 11, and the air inlet pipe 11 communicates with the inside of the heating chamber compartment and the outside of the main box body 1; under the action of the switch valve 12, the cold air enters the heating chamber compartment through the air inlet pipe 11 for heating.

[0033] An air outlet pipe 15 is provided above the tobacco loading chamber compartment. A check valve 14 and an exhaust and moisture removal fan 13 are provided on the air outlet pipe 15, and the air outlet pipe 15 communicates with the inside of the tobacco loading chamber compartment and the outside of the main box body 1; under the action of the exhaust and moisture removal fan 13, the excess hot and humid air during the tobacco leaf baking is discharged through the air outlet pipe 15.

[0034] The air inlet facility and the air outlet facility are arranged inside the top cover 4 on the main box body 1. A mesh air inlet 8 is provided on the side of the top cover 4. Under the action of the switch valve 12, the cold air evenly enters the inside of the top cover 4 through the air inlet 8 and enters the heating chamber compartment through the air inlet pipe 11 for heating. The design of the mesh air inlet 8 makes the entering cold air uniform and reduces the influence of impurities in the air on the baking process and the machine itself.

[0035] A moisture exhaust port 7 is also provided on the top cover 4, and the moisture exhaust port 7 communicates with the air outlet pipe 15 to discharge the air in the air outlet pipe 15.

[0036] The air flow direction of this graphene intelligent tobacco leaf baking test chamber: When the switch valve 12 is opened, cold air evenly enters the interior of the machine top cover from the air inlet 8, and enters the heating chamber through the air inlet pipe 11. The cold air is heated to a certain temperature by the graphene heating plate 16 during the sinking process. The heated hot air enters the tobacco loading chamber with tobacco leaves hanging from the lower part under the action of the circulation fan. The hot air bakes the tobacco leaves during the process of rising from the bottom to the top. The hot air then returns to the heating chamber from the upper part, forming an internal air circulation to bake the tobacco leaves. During the baking process, when the temperature of the humid hot air is higher than the set value, under the action of the moisture exhaust fan 13, the air is discharged from the moisture exhaust port 7 through the air outlet pipe 15 to keep the temperature and humidity in the tobacco loading chamber constant.

[0037] The upward air flow direction of the hot air from bottom to top is more in line with the physical laws and improves the thermal energy utilization rate. The cold air enters the heating chamber and sinks under the action of gravity. During this process, it is heated by the graphene heating plate 16. The heated air enters the heating chamber. Since the hot air expands in volume and has a smaller density, it moves upward from bottom to top in the heating chamber. During this process, the tobacco leaves are baked. This improves the thermal energy utilization rate and reduces energy loss compared with the downward method.

[0038] A heating chamber door 6 for easy maintenance is provided on one side of the heating chamber. The heating chamber door 6 provides convenience for maintenance and repair.

[0039] A tobacco loading chamber door 2 is provided on one side of the tobacco loading chamber.

[0040] The heating chamber door 6 and the tobacco loading chamber door 2 are arranged on opposite sides of the main box body 1.

[0041] A display screen 5 is also provided on the main box body 1. The display screen 5 is electrically connected to the vision camera to display the parameters of the test chamber.

[0042] Universal wheels for movement are provided at the bottom of the main box body 1.

[0043] Working principle

[0044] The switching valve 12 is opened, and cold air enters the inside of the top cover 4 of the test chamber from the air inlet 8. The design of the air inlet 8 enables the air to enter evenly and has a certain self-cleaning function, reducing the influence of impurities on the baking process. The cold air is sucked into the heating chamber by the switching valve 12 of the air inlet pipe 11. A graphene heating plate 16 is fixed in the heating chamber. Since the density of the cold air is relatively large, the cold air moves from top to bottom in the heating chamber and is heated by the graphene heating plate 16 during the sinking process. The hot air heated to a certain temperature enters the tobacco loading chamber containing tobacco leaves under the action of the bottom circulation fan. The density of the hot air is small, and the hot air moves from bottom to top in the baking chamber. During this process, the tobacco leaves are baked, and the moisture of the tobacco leaves is removed. Finally, the wet and cold air is discharged from the moisture exhaust port 7 through the air outlet pipe 15. The entire process can be observed and data collected through a visual camera, which plays an important role in the research of the baking process, the quality control of the baking process, and remote supervision, gradually realizing the "green and intelligent" baking of tobacco leaves.

However, it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
