[0026] The following will be described in conjunction with Figures 1-3 The atomizing device of the laboratory burley tobacco roaster and the laboratory burley tobacco roaster are described.

[0027] According to the atomizing device of the laboratory burley tobacco roaster provided in the embodiments of the present application, the atomizing device is installed on the oven 01 of the laboratory burley tobacco roaster, and the atomizing device comprises a rack 02, a mounting frame and an atomizing assembly. The rack 02 is fixed on the laboratory burley tobacco roaster; the mounting frame is slidingly installed on the rack 02; the atomizing assembly comprises a plurality of double-fluid nozzles 08 and a water pump 09. The double-fluid nozzles 08 are installed on the mounting frame, the spraying direction of the double-fluid nozzles 08 is parallel to the sliding direction of the mounting frame relative to the rack 02, the spraying end of the double-fluid nozzles 08 penetrates the inside of the oven 01, one end of the water pump 09 is connected with an external water source, and the other end of the water pump 09 is connected with the liquid inlet end of the plurality of double-fluid nozzles 08.

[0028] The atomization device of the laboratory burley tobacco roasting machine according to the embodiment of the present application can spray water mist into the oven 01 of the laboratory burley tobacco roasting machine through the design of the atomization assembly, so as to increase the humidity in the oven 01. Before the burley tobacco leaves enter the oven 01, the humidity in the oven 01 can be adjusted in advance by using the double-fluid nozzle 08, so that a certain humidity is maintained in the oven 01. The above design can avoid the temperature in the oven 01 from fluctuating greatly due to the heat absorption caused by the evaporation of water in the tobacco leaves during the initial heating stage of the burley tobacco leaves in the oven 01, and ensure the drying effect of the tobacco leaves. At the same time, since the double-fluid nozzle 08 sprays mist into the oven 01, the oven 01 has a certain humidity, and the tobacco leaves will not be dried too quickly. Through the design of the mounting bracket, the mounting bracket is slidingly installed on the rack 02, and the mounting bracket can be telescopically moved relative to the rack 02, so as to realize the position adjustment of the double-fluid nozzle 08 in the oven 01 and ensure the spraying effect. In addition, the above design also facilitates the disassembly and assembly of the double-fluid nozzle 08.

[0029] It can be understood that the rack 02 can be fixed on the oven 01 of the laboratory burley tobacco roasting machine by bolts or other fastening methods, so as to ensure the stability and reliability of the device.

[0030] The mounting bracket is slidingly installed on the rack 02, so that the mounting bracket can be telescopically moved along the rack 02, thereby adjusting the position of the double-fluid nozzle 08 in the oven 01 and ensuring that the spraying effect reaches the best.

[0031] The atomization assembly is composed of a plurality of double-fluid nozzles 08 and a water pump 09. The double-fluid nozzles 08 are responsible for spraying water mist into the oven 01, and the water pump 09 is responsible for conveying water from an external water source to the double-fluid nozzles 08. The double-fluid nozzle 08 is a high-efficiency spraying device that uses the mixture of high-pressure gas (such as compressed air) and low-pressure liquid (such as water) to generate fine water mist particles.

[0032] In the present application, the spraying direction of the double-fluid nozzle 08 is parallel to the sliding direction of the mounting bracket relative to the rack 02, and the spraying end penetrates the inside of the oven 01. This design enables the water mist to uniformly cover the burley tobacco leaves in the oven 01, thereby increasing the humidity in the oven 01.

[0033] According to one embodiment of the present application, the spraying direction of the double-fluid nozzle 08 is horizontally arranged.

[0034] It can be understood that the horizontal arrangement of the spraying direction can ensure the uniform distribution of water mist particles in the horizontal direction within the oven 01. Compared with the vertical or inclined spraying direction, the horizontal spraying can reduce the accumulation of water mist particles at the top or bottom of the oven 01, thereby improving the humidity uniformity within the entire oven 01. In addition, the tobacco leaves are usually placed horizontally, and the horizontal arrangement of the spraying direction helps to uniformly heat the burley tobacco leaves during the drying process, thereby improving the drying effect.

[0035] According to an embodiment of the present application, the atomization assembly comprises a plurality of adjusting valves 10, at least one adjusting valve 10 is arranged corresponding to each double-fluid nozzle 08, and the adjusting valve 10 is arranged between the water pump 09 and the liquid inlet end of the double-fluid nozzle 08.

[0036] It can be understood that the adjusting valve 10 can accurately control the spraying amount of each double-fluid nozzle 08. According to the drying needs of the burley tobacco leaves and the actual situation within the oven 01, the operator can flexibly adjust the spraying amount through the adjusting valve 10. This helps to optimize the spraying effect, ensures that the tobacco leaves can be uniformly heated during the drying process, and improves the drying efficiency and quality.

[0037] In one embodiment, the liquid inlet end of the double-fluid nozzle is connected to a water pump, and the gas inlet end of the double-fluid nozzle is connected to a gas pump.

[0038] According to an embodiment of the present application, the atomization assembly comprises a plurality of gas flow meters 11, at least one gas flow meter 11 is arranged corresponding to each double-fluid nozzle 08, and the gas flow meter 11 is arranged at the gas inlet end of the double-fluid nozzle 08.

[0039] It can be understood that the gas flow meter 11 can accurately measure the gas flow of each double-fluid nozzle 08, and ensure that the mixing ratio of gas and liquid reaches the best.

[0040] According to an embodiment of the present application, in the case where the atomization assembly comprises a plurality of adjusting valves 10 and a plurality of gas flow meters 11: the adjusting valves 10 and the gas flow meters 11 are both fixed on the rack 02.

[0041] It can be understood that fixing the adjusting valves 10 and the gas flow meters 11 on the rack 02 can avoid their movement or vibration during operation, thereby improving the stability of the entire atomization assembly. This helps to ensure the uniformity and stability of the spraying effect, and improves the operation efficiency of the equipment.

[0042] According to an embodiment of the present application, the gas flow meter 11 is a float type flow meter. The float type flow meter is reliable in operation and high in adjusting precision.

[0043] According to an embodiment of the present application, the water pump 09 is a peristaltic pump. The peristaltic pump is high in precision and stable in operation.

[0044] According to one embodiment of the present application, the mounting frame comprises an adjusting pipe 03, a plug rod 04, a plurality of sliding blocks 05, and a plurality of connecting rods 06. The adjusting pipe 03 is horizontally arranged, and the outer side wall thereof is vertically fixed with the plug rod 04. The plug rod 04 is horizontally arranged, and the rack 02 is provided with a plug hole 020. The plug rod 04 is slidingly inserted into the plug hole 020. Long strip holes 030 are formed in the upper and lower side walls of the adjusting pipe 03. The length direction of the long strip holes 030 is the same as the length direction of the adjusting pipe 03. The sliding blocks 05 are arranged in correspondence with the number of the double-fluid nozzles 08. The sliding blocks 05 are slidingly embedded in the adjusting pipe 03. The connecting rods 06 are arranged in correspondence with the number of the sliding blocks 05. The connecting rods 06 are vertically arranged. The upper end of each connecting rod 06 is fixed with the corresponding sliding block 05 after passing through a long strip hole 030. The lower end of each connecting rod 06 is fixed with a double-fluid nozzle 08. The spraying direction of the double-fluid nozzle 08 is perpendicular to the length direction of the connecting rod 06.

[0045] The adjusting pipe 03 is horizontally arranged as the main structure of the mounting frame. The outer side wall thereof is vertically fixed with the plug rod 04, which is horizontally arranged to cooperate with the plug hole 020 on the rack 02, thereby realizing the sliding installation of the mounting frame. The plug rod 04 is fixed on the outer side wall of the adjusting pipe 03 and forms an integral body with the adjusting pipe 03. The number and position of the plug rod 04 can be adjusted according to actual needs to ensure the stability and flexibility of the mounting frame. The rack 02 is provided with the plug hole 020 matched with the plug rod 04. The plug rod 04 can be slidingly inserted into the plug hole 020, thereby realizing the horizontal sliding adjustment of the mounting frame on the rack 02.

[0046] Long strip holes 030 are formed in the upper and lower side walls of the adjusting pipe 03. The length direction of the long strip holes 030 is the same as the length direction of the adjusting pipe 03, which is used to accommodate and guide the sliding of the sliding blocks 05 and the connecting rods 06. The sliding blocks 05 are arranged in correspondence with the number of the double-fluid nozzles 08 and are slidingly embedded in the adjusting pipe 03. The sliding blocks 05 can freely slide in the long strip holes 030, thereby driving the connecting rods 06 and the double-fluid nozzles 08 to adjust up and down. The connecting rods 06 are arranged in correspondence with the number of the sliding blocks 05 and are vertically arranged. The upper end of each connecting rod 06 is fixed with the corresponding sliding block 05 after passing through a long strip hole 030, and the lower end is fixed with a double-fluid nozzle 08. The connecting rods 06 serve as a bridge to connect the sliding blocks 05 and the double-fluid nozzles 08 together to form an integral structure.

[0047] It can be understood that the mounting frame can be horizontally slidably adjusted on the rack 02 through the cooperation of the insertion rod 04 and the insertion hole 020. This helps to flexibly adjust the position of the double-fluid nozzle 08 according to the arrangement and quantity of the burley tobacco leaves in the oven 01, so as to ensure that the spraying effect is optimal. The sliding adjustment of the sliding block 05 in the long slot hole 030 can drive the connecting rod 06 and the double-fluid nozzle 08 to be horizontally adjusted left and right. This helps to accurately control the spraying density of the double-fluid nozzle 08 according to the humidity requirements of different areas in the oven 01, thereby improving the spraying effect.

[0048] According to one embodiment of the present application, the mounting frame comprises a plurality of compression bolts 07, at least one compression bolt 07 is arranged corresponding to each sliding block 05, one end of each compression bolt 07 is threadedly screwed with the corresponding sliding block 05 after penetrating through another long slot hole 030, and the compression bolt cap of the compression bolt 07 can be tightly abutted against the upper side wall of the adjusting pipe 03.

[0049] One end of the compression bolt 07 is threadedly screwed with the corresponding sliding block 05 after penetrating through the long slot hole 030 on the adjusting pipe 03. By rotating the compression bolt 07, it can be tightly abutted against the upper side wall of the adjusting pipe 03, thereby firmly fixing the sliding block 05 in the adjusting pipe 03.

[0050] The fixing effect of the compression bolt 07 helps to improve the stability of the entire mounting frame. When the double-fluid nozzle 08 is spraying, a certain reaction force will be generated. The presence of the compression bolt 07 can ensure that the sliding block 05 and the connecting rod 06 will not move or vibrate due to these reaction forces, thereby ensuring the stability and accuracy of the spraying effect.

[0051] The threadedly screwed manner of the compression bolt 07 makes it convenient to adjust the tightness. When it is necessary to adjust the position of the sliding block 05, the compression bolt 07 is only loosened, then the sliding block 05 is slid to the desired position, and the compression bolt 07 is tightened. This adjustment method is simple and fast, which greatly improves the work efficiency.

[0052] According to one embodiment of the present application, the rack 02 is provided with a threaded hole penetrating the insertion hole 020, and a jacking bolt 12 is threadedly screwed in the threaded hole, and the jacking bolt 12 is used to tightly abut against the outer side wall of the insertion rod 04 to fix the insertion rod 04.

[0053] It can be understood that the jacking bolt 12 is threadedly screwed into the threaded hole on the rack 02 and tightly abuts against the outer side wall of the insertion rod 04, thereby firmly fixing the insertion rod 04 on the rack 02. This fixing method is simple and effective, which can ensure that the mounting frame will not move or vibrate during the spraying process.

[0054] The screwing mode of the top bolt 12 is convenient for adjusting the tightness. When the position of the mounting frame needs to be adjusted, the top bolt 12 is loosened, the mounting frame is slid to the desired position, and then the top bolt 12 is screwed. The adjustment is simple and fast, and the work efficiency is greatly improved.

[0055] In one embodiment, a temperature and humidity monitoring module and a temperature sensor are installed in the oven 01. The worker can adjust the regulating valve 10 and the gas flow meter 11 according to the humidity in the oven 01, and control the spraying time of the double-fluid nozzle 08, thereby improving the drying effect of the oven 01 on the tobacco leaves.

[0056] According to the second aspect of the present application, the laboratory white burley tobacco roasting machine comprises: The oven 01 is provided with an inlet 010. The conveying belt 13 is arranged on the lower side of the oven 01, and a hot air outlet is arranged below the conveying belt 13. The above-mentioned laboratory white burley tobacco roasting machine atomizing device is installed on the oven 01, and the double-fluid nozzle 08 of the atomizing device is connected to the inlet 010 of the oven 01. The sliding direction of the mounting frame is the same as the moving direction of the tobacco leaves on the conveying belt 13.

[0057] The oven 01 is provided with one or more roasting areas for heating and roasting the white burley tobacco. The oven 01 is provided with an inlet 010, and the double-fluid nozzle 08 of the atomizing device is connected to the inlet 010 of the oven 01, so as to uniformly spray the atomized water or solution onto the white burley tobacco entering the oven 01.

[0058] The conveying belt 13 is arranged on the lower side of the oven 01 and used for carrying and conveying the white burley tobacco. The material of the conveying belt 13 should have good heat resistance and wear resistance to ensure stable operation in a long-time high-temperature environment. A hot air outlet is arranged below the conveying belt 13, and hot air is uniformly blown to the white burley tobacco on the conveying belt 13 through the hot air outlet, realizing hot air circulation and heating effect.

[0059] The spraying direction of the double-fluid nozzle 08 of the atomizing device is consistent with the moving direction of the conveying belt 13, so as to realize uniform distribution and effective utilization of the atomized droplets. The sliding direction of the mounting frame is the same as the moving direction of the tobacco leaves on the conveying belt 13, so that the atomizing device can accurately adjust the position of the double-fluid nozzle 08, which helps to improve the roasting effect of the white burley tobacco.

[0060] According to one embodiment of the present application, the white burley tobacco roasting machine comprises a temperature and humidity monitoring module, which is arranged in the oven. The temperature and humidity monitoring module is used for detecting the temperature and humidity of the tobacco leaf sample on the conveying belt.

[0061] It can be understood that the temperature and humidity monitoring module can detect the temperature of the tobacco or tobacco shred in the baking process. The temperature and humidity monitoring module can record the temperature data of the tobacco sample at certain time intervals and transmit the temperature data to the controller. The controller is provided with a preset temperature fluctuation curve. By comparing the fluctuation amplitude of the temperature data with the preset temperature fluctuation curve, the position of the double-fluid nozzle 08 or the power of the hot air fan is adjusted in real time based on the comparison result, so as to timely adjust the humidity inside the oven, avoid large temperature fluctuations of the tobacco or tobacco shred in the initial heating stage, and improve the production quality of the tobacco.

[0062] It should be noted that the oven 01 of the present application takes the hot air fan as the heat source.

[0063] Specifically, if the fluctuation amplitude of the temperature data is less than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco is too high. The power of the hot air fan can be controlled to increase the temperature inside the oven 01. The position of the double-fluid nozzle 08 can be changed by changing the position of the sliding block 06 on the adjusting pipe 03, so as to change the humidity of the local position. The position of the double-fluid nozzle 08 can be changed by changing the telescopic position of the mounting bracket on the rack 02, so as to change the humidity of the local position. The humidity can also be reduced by reducing the water output of the double-fluid nozzle 08.

[0064] If the fluctuation amplitude of the temperature data is greater than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco is too low. The power of the hot air fan can be controlled to reduce the temperature inside the oven 01. The position of the double-fluid nozzle 08 can be changed by changing the position of the sliding block 06 on the adjusting pipe 03, so as to change the humidity of the local position. The position of the double-fluid nozzle 08 can be changed by changing the telescopic position of the mounting bracket on the rack 02, so as to change the humidity of the local position. The humidity can also be increased by increasing the water output of the double-fluid nozzle 08.

[0065] Of course, the temperature and humidity monitoring module can also detect the humidity of the tobacco or tobacco shred in the baking process. The temperature and humidity monitoring module can record the humidity data of the tobacco sample at certain time intervals and transmit the humidity data to the controller. The controller is provided with a preset humidity fluctuation curve. By comparing the fluctuation amplitude of the humidity data with the preset humidity fluctuation curve, the position of the double-fluid nozzle 08 or the power of the hot air fan is adjusted in real time based on the comparison result, so as to timely adjust the humidity inside the oven, avoid large humidity fluctuations of the tobacco or tobacco shred in the initial heating stage, and improve the production quality of the tobacco.

[0066] Similarly, if the fluctuation amplitude of the temperature data is less than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco leaves is too high. The power of the hot air fan can be controlled to increase the temperature inside the oven 01. The position of the sliding block 06 on the adjusting pipe 03 can be changed to change the position of the double-fluid nozzle 08 to change the humidity of the local position. The telescopic position of the mounting frame on the rack 02 can be changed to change the position of the double-fluid nozzle 08 to change the humidity of the local position. The water output of the double-fluid nozzle 08 can be reduced to reduce the humidity.

[0067] If the fluctuation amplitude of the temperature data is greater than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco leaves is too low. The power of the hot air fan can be controlled to reduce the temperature inside the oven 01. The position of the sliding block 06 on the adjusting pipe 03 can be changed to change the position of the double-fluid nozzle 08 to change the humidity of the local position. The telescopic position of the mounting frame on the rack 02 can be changed to change the position of the double-fluid nozzle 08 to change the humidity of the local position. The water output of the double-fluid nozzle 08 can be increased to increase the humidity.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones.
