Description

[0002] Burley tobacco leaves require a relatively stable drying temperature during the drying process. However, in reality, when tobacco leaves with a certain amount of moisture enter an oven with extremely low humidity and constant temperature, the oven temperature fluctuates drastically as the moisture in the tobacco leaves evaporates rapidly and absorbs heat. This temperature fluctuation exceeds the set threshold for the tobacco leaf drying temperature, thus affecting the drying effect. In addition, tobacco leaves need to be dried gradually. Rapid evaporation of moisture in the early stages can lead to excessively fast drying, thereby affecting the drying quality.

[0027] The following is combined with Figures 1-3 This invention describes the atomizing device for a laboratory burley tobacco roaster and the laboratory burley tobacco roaster.

[0028] The atomizing device for a laboratory burley tobacco roaster according to an embodiment of this application is installed on oven 01 of the laboratory burley tobacco roaster. The atomizing device includes:

[0029] Mounting rack, which can slide relative to laboratory burley smoke roaster oven 01;

[0030] The atomizing assembly includes multiple dual-fluid nozzles 08 mounted on a mounting bracket. The atomizing assembly is configured to achieve lateral atomization coverage within the oven 01 through horizontal spraying of the dual-fluid nozzles 08, and longitudinal atomization coverage through linear movement of the mounting bracket.

[0031] According to the embodiment of this application, the atomizing device of the laboratory burley tobacco roaster achieves lateral atomization coverage inside the oven 01 through horizontal spraying of the dual-fluid nozzle 08; and achieves longitudinal atomization coverage through linear movement of the mounting frame, thus solving the defect of poor drying effect caused by large temperature fluctuations in existing burley tobacco leaves inside the oven 01.

[0032] According to one embodiment of this application, the atomizing device of the laboratory burley tobacco roaster includes a frame 02, which is mounted on the oven 01 of the laboratory burley tobacco roaster. A mounting bracket is slidably connected to the frame 02, and the sliding direction of the mounting bracket is parallel to the moving direction on the conveyor belt 13 of the laboratory burley tobacco roaster.

[0033] According to one embodiment of this application, the atomizing component includes a water pump 09 and an air pump. One end of the water pump 09 is connected to an external water source, and the other end of the water pump 09 is connected to the liquid inlet of a plurality of dual-fluid nozzles 08. One end of the air pump is connected to external gas, and the other end of the air pump is connected to the air inlet of a plurality of dual-fluid nozzles 08.

[0034] According to one embodiment of this application, the atomizing assembly includes a plurality of regulating valves 10, and each dual-fluid nozzle 08 has an independent regulating valve 10 at its inlet end.

[0035] According to one embodiment of this application, the atomizing assembly includes a gas flow meter 11, and each dual-fluid nozzle 08 has an independent gas flow meter 11 at its air inlet end.

[0036] According to one embodiment of this application, the mounting bracket includes an adjusting tube 03, a slider 05, and a connecting rod 06. The adjusting tube 03 is arranged horizontally, and a slidable slider 05 is provided inside the adjusting tube 03. The slider 05 is fixed to the dual-fluid nozzle 08 by the connecting rod 06.

[0037] According to one embodiment of this application, a universal joint (not shown in the figure) is provided between the connecting rod 06 and the dual-fluid nozzle 08. The universal joint is fixed by a locking nut to realize the fine adjustment of the angle of the dual-fluid nozzle 08 in three-dimensional space.

[0038] According to the embodiment of this application, the atomizing device for a laboratory burley tobacco roaster is installed on the oven 01 of the laboratory burley tobacco roaster. The atomizing device includes a frame 02, a mounting bracket, and an atomizing assembly. The frame 02 is fixed on the laboratory burley tobacco roaster. The mounting bracket is slidably installed on the frame 02. The atomizing assembly includes several dual-fluid nozzles 08 and a water pump 09. The dual-fluid nozzles 08 are installed on the mounting bracket. The spray direction of the dual-fluid nozzles 08 is parallel to the sliding direction of the mounting bracket relative to the frame 02. The spray end of the dual-fluid nozzles 08 passes through the inside of the oven 01. One end of the water pump 09 is connected to an external water source, and the other end of the water pump 09 is connected to the liquid inlet end of the multiple dual-fluid nozzles 08.

[0039] According to the atomizing device of the laboratory burley tobacco roaster according to the embodiments of this application, by designing the atomizing component, the dual-fluid nozzle 08 in the atomizing component can spray water mist into the oven 01 of the laboratory burley tobacco roaster, thereby increasing the humidity inside the oven 01. Before the burley tobacco leaves enter the oven 01, the humidity inside the oven 01 can be pre-adjusted by the dual-fluid nozzle 08 to maintain a certain humidity inside the oven 01. The above design can avoid large temperature fluctuations inside the oven 01 due to the heat absorption effect of water evaporation in the tobacco leaves during the initial heating stage inside the oven 01, thus ensuring the drying effect of the tobacco leaves. At the same time, because the dual-fluid nozzle 08 sprays into the oven 01, the oven 01 has a certain humidity, and the tobacco leaves will not dry too quickly. By designing the mounting bracket, the mounting bracket is slidably mounted on the frame 02, and the mounting bracket can extend and retract relative to the frame 02, thereby realizing the position adjustment of the dual-fluid nozzle 08 inside the oven 01 to ensure the spraying effect. In addition, the above design also facilitates the disassembly and assembly of the dual-fluid nozzle 08.

[0040] Understandably, the frame 02 can be securely fixed to the oven 01 of the laboratory burley tobacco roaster by bolts or other fastening methods to ensure the stability and reliability of the device.

[0041] The mounting bracket adopts a sliding installation method, forming a sliding engagement with the frame 02. This allows the mounting bracket to extend and retract along the frame 02, thereby adjusting the position of the dual-fluid nozzle 08 within the oven 01 to ensure optimal spraying effect.

[0042] The atomizing assembly consists of several dual-fluid nozzles 08 and a water pump 09. The dual-fluid nozzles 08 are responsible for spraying water mist into the oven 01, while the water pump 09 is responsible for delivering water from an external water source to the dual-fluid nozzles 08. The dual-fluid nozzles 08 are highly efficient spraying devices that utilize the mixing of high-pressure gas (such as compressed air) and low-pressure liquid (such as water) to produce fine water mist particles.

[0043] In this invention, the spray direction of the dual-fluid nozzle 08 is parallel to the sliding direction of the mounting bracket relative to the frame 02, and the spray end is inserted inside the oven 01. This design allows water mist to evenly cover the burley tobacco leaves inside the oven 01, increasing the humidity inside the oven 01.

[0044] According to one embodiment of this application, the jetting direction of the dual-fluid nozzle 08 is arranged horizontally.

[0045] Understandably, a horizontally arranged spray direction ensures that water mist particles are evenly distributed horizontally within the oven 01. Compared to vertical or inclined spray directions, horizontal spraying reduces the accumulation of water mist particles at the top or bottom of the oven 01, thereby improving the humidity uniformity throughout the oven 01. Furthermore, since tobacco leaves are typically arranged horizontally, a horizontally arranged spray direction helps burley tobacco leaves to be heated evenly during the drying process, improving the drying effect.

[0046] According to one embodiment of this application, the atomizing assembly includes a plurality of regulating valves 10, and each dual-fluid nozzle 08 is provided with at least one regulating valve 10, the regulating valve 10 being located between the water pump 09 and the liquid inlet end of the dual-fluid nozzle 08.

[0047] Understandably, the regulating valve 10 precisely controls the spray volume of each dual-fluid nozzle 08. Based on the drying requirements of the burley tobacco leaves and the actual conditions within the oven 01, the operator can flexibly adjust the spray volume using the regulating valve 10. This helps optimize the spraying effect, ensuring the tobacco leaves are heated evenly during the drying process, thus improving drying efficiency and quality.

[0048] In one embodiment, the liquid inlet of the dual-fluid nozzle is connected to a water pump, and the air inlet of the dual-fluid nozzle is connected to an air pump.

[0049] According to one embodiment of this application, the atomizing assembly includes a plurality of gas flow meters 11, and each dual-fluid nozzle 08 is provided with at least one gas flow meter 11, the gas flow meter 11 being located at the air inlet end of the dual-fluid nozzle 08.

[0050] Understandably, the gas flow meter 11 is able to accurately measure the gas flow rate of each dual-fluid nozzle 08, ensuring that the mixing ratio of gas and liquid is optimal.

[0051] According to one embodiment of this application, in the case where the atomizing assembly includes a plurality of regulating valves 10 and a plurality of gas flow meters 11: both the regulating valves 10 and the gas flow meters 11 are fixed on the frame 02.

[0052] Understandably, fixing the regulating valve 10 and the gas flow meter 11 to the frame 02 prevents them from moving or vibrating during operation, thereby improving the stability of the entire atomizing assembly. This helps ensure the uniformity and stability of the spray effect and improves the operating efficiency of the equipment.

[0053] According to one embodiment of this application, the gas flow meter 11 is a float-type flow meter. Float-type flow meters are reliable in operation and have high adjustment accuracy.

[0054] According to one embodiment of this application, pump 09 is a peristaltic pump. Peristaltic pumps offer high precision and stable operation.

[0055] According to one embodiment of this application, the mounting frame includes an adjusting tube 03, a plug rod 04, a plurality of sliders 05, and a plurality of connecting rods 06. The adjusting tube 03 is horizontally arranged and the plug rod 04 is vertically fixed to its outer side wall. The plug rod 04 is horizontally arranged, and the frame 02 is provided with a plug hole 020. The plug rod 04 is slidably inserted into the plug hole 020. The upper and lower side walls of the adjusting tube 03 are provided with elongated holes 030. The length direction of the elongated holes 030 is the same as the length direction of the adjusting tube 03. The number of sliders 05 corresponds to the number of dual-fluid nozzles 08. The sliders 05 are all slidably embedded in the adjusting tube 03. The number of connecting rods 06 corresponds to the number of sliders 05. The connecting rods 06 are all vertically arranged. The upper end of each connecting rod 06 passes through an elongated hole 030 and is fixed to the corresponding slider 05. The lower end of each connecting rod 06 is fixed with a dual-fluid nozzle 08. The spray direction of the dual-fluid nozzle 08 is perpendicular to the length direction of the connecting rod 06.

[0056] The adjusting tube 03 is horizontally arranged and serves as the main structure of the mounting frame. A horizontally arranged insert rod 04 is vertically fixed to its outer wall, used to mate with the insertion hole 020 on the frame 02 to achieve sliding installation of the mounting frame. The insert rod 04 is fixed to the outer wall of the adjusting tube 03, forming a single unit with it. The number and position of the insert rods 04 can be adjusted according to actual needs to ensure the stability and flexibility of the mounting frame. The frame 02 is provided with insertion holes 020 that match the insert rods 04. The insert rods 04 can be slidably inserted into the insertion holes 020, thereby achieving horizontal sliding adjustment of the mounting frame on the frame 02.

[0057] The upper and lower sidewalls of the regulating tube 03 are provided with elongated holes 030. The length direction of the elongated holes 030 is the same as that of the regulating tube 03, and they are used to accommodate and guide the sliding of the sliders 05 and the connecting rods 06. The number of sliders 05 corresponds to the number of dual-fluid nozzles 08, and they are all slidably embedded in the regulating tube 03. The sliders 05 can slide freely within the elongated holes 030, thereby driving the connecting rods 06 and the dual-fluid nozzles 08 to adjust up and down. The number of connecting rods 06 corresponds to the number of sliders 05, and they are all arranged vertically. The upper end of each connecting rod 06 passes through an elongated hole 030 and is fixed to the corresponding slider 05, while the lower end is fixed to a dual-fluid nozzle 08. The connecting rods 06 act as a bridge, connecting the sliders 05 and the dual-fluid nozzles 08 together to form an integral structure.

[0058] Understandably, the mounting bracket can slide horizontally on the frame 02 through the cooperation of the insertion rod 04 and the insertion hole 020. This helps to flexibly adjust the position of the dual-fluid nozzle 08 according to the arrangement and quantity of burley tobacco leaves in the oven 01, ensuring optimal spraying effect. The sliding adjustment of the slider 05 within the elongated hole 030 can drive the connecting rod 06 and the dual-fluid nozzle 08 to adjust horizontally left and right. This helps to precisely control the spray density of the dual-fluid nozzle 08 according to the humidity requirements of different areas within the oven 01, improving the spraying effect.

[0059] According to one embodiment of this application, the mounting bracket includes a plurality of clamping bolts 07, and each slider 05 is provided with at least one clamping bolt 07. One end of each clamping bolt 07 is threadedly connected to the corresponding slider 05 after passing through another elongated hole 030. The bolt head of the clamping bolt 07 can abut against the upper side wall of the adjusting tube 03.

[0060] One end of the clamping bolt 07 passes through the elongated hole 030 on the adjusting tube 03 and is threaded onto the corresponding slider 05. By rotating the clamping bolt 07, it can be pressed against the upper side wall of the adjusting tube 03, thereby firmly fixing the slider 05 inside the adjusting tube 03.

[0061] The clamping bolt 07 helps improve the stability of the entire mounting bracket. When the dual-fluid nozzle 08 sprays, it generates a certain reaction force. The presence of the clamping bolt 07 ensures that the slider 05 and connecting rod 06 will not move or vibrate due to these reaction forces, thus guaranteeing the stability and accuracy of the spray effect.

[0062] The threaded connection of the clamping bolt 07 allows for easy adjustment of its tightness. When the position of the slider 05 needs adjustment, simply loosen the clamping bolt 07, slide the slider 05 to the desired position, and then tighten the clamping bolt 07. This adjustment method is simple and quick, greatly improving work efficiency.

[0063] According to one embodiment of this application, the frame 02 is provided with a threaded hole through the insertion hole 020, and a tightening bolt 12 is screwed into the threaded hole. The tightening bolt 12 is used to press against the outer wall of the insertion rod 04 to fix the insertion rod 04.

[0064] Understandably, the tightening bolt 12 is screwed into the threaded hole on the frame 02 and abuts against the outer wall of the insert rod 04, thereby firmly fixing the insert rod 04 to the frame 02. This fixing method is simple and effective, ensuring that the mounting bracket will not move or vibrate during spraying.

[0065] The threaded connection of the tightening bolt 12 allows for easy adjustment of its tightness. When the position of the mounting bracket needs to be adjusted, simply loosen the tightening bolt 12, slide the mounting bracket to the desired position, and then tighten the tightening bolt 12. This adjustment method is simple and quick, greatly improving work efficiency.

[0066] In one embodiment, the oven 01 is equipped with a temperature and humidity monitoring module and a temperature sensor. The operator can adjust the regulating valve 10 and the gas flow meter 11 according to the humidity inside the oven 01, and at the same time control the spraying time of the dual-fluid nozzle 08, thereby improving the drying effect of the oven 01 on the tobacco leaves.

[0067] A laboratory burley tobacco roaster according to a second aspect embodiment of this application includes:

[0068] Oven 01, equipped with entrance 010;

[0069] Conveyor belt 13 is located below oven 01, and hot air outlet is provided below conveyor belt 13;

[0070] The aforementioned laboratory burley tobacco roaster atomizing device is mounted on the oven 01. The dual-fluid nozzle 08 of the atomizing device is connected to the inlet 010. The sliding direction of the mounting bracket is the same as the moving direction of the tobacco leaves on the conveyor belt 13.

[0071] The oven 01 has one or more baking zones inside for heating and baking burley tobacco. The oven 01 is equipped with a dual-fluid nozzle 08 of an inlet 010 atomizing device connected to the inlet 010 of the oven 01, so as to evenly spray atomized water or solution onto the burley tobacco entering the oven 01.

[0072] Conveyor belt 13 is located below oven 01 and is used to carry and transport burley smoke. The material of conveyor belt 13 should have good heat resistance and wear resistance to ensure stable operation under long-term high-temperature environment. A hot air outlet is provided below conveyor belt 13, and hot air is blown evenly onto the burley smoke on conveyor belt 13 through the hot air outlet to achieve hot air circulation and heating effect.

[0073] The spray direction of the dual-fluid nozzle 08 of the atomizing device is consistent with the moving direction of the conveyor belt 13 to achieve uniform distribution and effective utilization of atomized droplets. The sliding direction of the mounting bracket is the same as the moving direction of the tobacco leaves on the conveyor belt 13, which allows the atomizing device to precisely adjust the position of the dual-fluid nozzle 08, helping to improve the roasting effect of Burley tobacco.

[0074] According to one embodiment of this application, the burley tobacco roasting machine includes a temperature and humidity monitoring module located inside the oven. The temperature and humidity monitoring module is used to detect the temperature and humidity of the tobacco leaf samples on the conveyor belt.

[0075] Understandably, the temperature and humidity monitoring module can detect the temperature of tobacco leaves or shredded tobacco during roasting. This module records temperature data from tobacco leaf samples at regular time intervals and transmits the data to the controller. The controller has a preset temperature fluctuation curve. By comparing the fluctuation range of the temperature data with the preset curve, the controller adjusts the position of the dual-fluid nozzle 08 or the power of the hot air blower in real time based on the comparison results. This promptly adjusts the humidity inside the oven, preventing significant temperature fluctuations in the tobacco leaves or shredded tobacco during the initial heating phase and improving the quality of the roasted tobacco.

[0076] It should be noted that the oven 01 in this application uses a hot air blower as its heat source.

[0077] Specifically, if the temperature fluctuation is less than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco leaves is too high. This can be addressed by increasing the power of the hot air blower to raise the temperature inside the oven 01, changing the position of the slider 06 on the regulating pipe 03 to change the position of the dual-fluid nozzle 08, thereby changing the humidity in a localized area, changing the extension position of the mounting bracket on the frame 02 to change the position of the dual-fluid nozzle 08, or reducing the water output of the dual-fluid nozzle 08.

[0078] If the temperature fluctuation is greater than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco leaves is too low. This can be addressed by reducing the power of the hot air blower to lower the temperature inside the oven 01, changing the position of the slider 06 on the regulating pipe 03 to change the position of the dual-fluid nozzle 08, thereby changing the humidity in a localized area, changing the extension position of the mounting bracket on the frame 02 to change the position of the dual-fluid nozzle 08, or increasing the water output of the dual-fluid nozzle 08 to increase humidity.

[0079] Of course, the temperature and humidity monitoring module can also detect the humidity of tobacco leaves or shredded tobacco during roasting. The temperature and humidity monitoring module can record the humidity data of tobacco leaf samples at certain time intervals and transmit the humidity data to the controller. The controller has a preset humidity fluctuation curve. By comparing the fluctuation amplitude of the humidity data with the preset humidity fluctuation curve, the position of the dual-fluid nozzle 08 or the power of the hot air blower is adjusted in real time based on the comparison result, thereby adjusting the humidity inside the oven in a timely manner, avoiding large humidity fluctuations in tobacco leaves or shredded tobacco during the initial heating stage, and improving the quality of tobacco production.

[0080] Similarly, if the fluctuation range 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 humidity can be changed by increasing the power of the hot air blower to increase the temperature inside the oven 01, or by changing the position of the slider 06 on the regulating pipe 03 to change the position of the dual-fluid nozzle 08, thereby changing the humidity of the local area. Alternatively, the humidity can be changed by changing the extension position of the mounting bracket on the frame 02 to change the position of the dual-fluid nozzle 08, or by reducing the water output of the dual-fluid nozzle 08.

[0081] If the temperature fluctuation is greater than the preset temperature fluctuation curve, it indicates that the humidity of the tobacco leaves is too low. This can be addressed by reducing the power of the hot air blower to lower the temperature inside the oven 01, changing the position of the slider 06 on the regulating pipe 03 to change the position of the dual-fluid nozzle 08, thereby changing the humidity in a localized area, changing the extension position of the mounting bracket on the frame 02 to change the position of the dual-fluid nozzle 08, or increasing the water output of the dual-fluid nozzle 08 to increase humidity.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
