Description

Technical Field

[0001] The invention relates to a serial two-stage tobacco shred mixing and flavoring device and method, belonging to the technical field of tobacco processing. Background Art

[0002] In the tobacco production process, tobacco flavoring and mixing is a crucial step. By controlling the blending ratio of shredded tobacco and the type of sprayed flavors, tobacco products of different flavors and qualities can be obtained, thereby improving the overall quality of the finished tobacco.

[0003] Traditional flavoring devices are usually drum-type tobacco flavoring machines, which work by feeding the material into the drum and then rotating the drum to achieve flavoring and mixing of the tobacco. In order to improve the uniformity of mixed flavoring, rake nails or copying plates are often installed in the drum to increase the accumulation angle of the tobacco during the rotation of the drum. However, this method has the problem of high tobacco crushing rate. Since the tobacco is not fully broken up, "caking" is likely to occur during the rolling mixing process, resulting in uneven tobacco flavoring and affecting quality. In addition, the drum-type flavoring mechanism is heavy, complex in structure, difficult to maintain, and easily affects the production progress.

[0004] In recent years, the invention of flavoring machines based on cyclone separators has solved the problems of complex structure and difficult maintenance of traditional equipment, and improved the flavoring efficiency through tobacco fluidization. However, the residence time of tobacco in the cyclone separator is short, resulting in the inability of tobacco to be fully mixed with surrounding tobacco, so that the product cannot reach the ideal mixing state. Moreover, the common circulating air duct design will also cause the generation of flavors in the air duct to adsorb the wall surface during the tobacco flavoring process, which is not conducive to product quality control and subsequent equipment maintenance.

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example 1

[0024] See also Figure 1The present embodiment introduces a serial two-stage tobacco mixing and flavoring device, including a transport device, a serial two-stage device and a flavoring device, wherein the transport device includes a material transport conveyor belt (a feed conveyor belt 12, a discharge conveyor belt 16), a gas transport pipeline 10, a feed funnel 13, a feed funnel valve 14 and a blower 15, wherein the feed funnel 13 is located below the feed conveyor belt 12 so that the tobacco can slide directly from the conveyor belt into the feed funnel 13, the feed funnel 13 is equipped with a feed funnel valve 14 for adjusting the flow rate or flow of the tobacco from the feed funnel 13 into the gas transport pipeline 10, and the blower 15 is used to drive the airflow in the gas transport pipeline 10 to feed the tobacco through the feed funnel 13 and the gas transport pipeline 10 into the feed port 8 of the serial two-stage device.

[0025] The serial two-stage device comprises a first shell 2 and a second shell 3 connected in series, wherein the first shell 2 is a conical shell and has a lateral opening on the top, which serves as a feed port 8 for tobacco shreds. The second shell 3 is a hemispherical and conical combination connected to the first shell 2. A third shell 5 is also embedded in the second shell 3, and a gas distribution plate 11 is installed at the air inlet of the third shell 5. The gas distribution plate 11 is detachably connected to the gas transport pipeline 10 for easy cleaning and maintenance.

[0026] The flavoring device includes an atomizing nozzle 9, which is built into the first shell 2. A discharge port 6 is provided at the bottom of the second shell 3. The discharge port 6 is located above the discharge conveyor belt 16, and a discharge valve 7 is installed correspondingly to control the outflow of the mixed and flavored tobacco to ensure that the tobacco enters the discharge conveyor belt 16 smoothly. The discharge conveyor belt 16 is built into a dust cover 17. The dust cover 17 includes a dust collection system and a filtering system, which are used to collect and filter the dust generated during the discharge process to reduce environmental pollution and improve the cleanliness of the working environment.

[0027] Furthermore, the feed conveyor belt 12 is equipped with a plurality of weighing conveyor belts, which are arranged in parallel, and each feed conveyor belt 12 is equipped with a weighing sensor to weigh the tobacco shreds, and the feeding speed of the feed conveyor belt 12 is controlled according to the different weights of the tobacco shreds to blend tobacco shreds in different proportions. For example, if different types of tobacco shreds need to be mixed in a ratio of 3:2, by adjusting the speed of the feed conveyor belt 12, the faster conveyor belt conveys 3 portions of tobacco shreds, while the slower feed conveyor belt 12 conveys 2 portions of tobacco shreds, thereby producing tobacco products with specific taste and quality, and improving the consistency and quality of tobacco products.

[0028] Furthermore, the blower 15 can provide a temperature-controllable constant temperature airflow to meet the specific temperature requirements during the tobacco mixing and flavoring process. Good temperature control helps to optimize the absorption of flavors by tobacco while ensuring the stability of product quality. The blower 15 can also provide different gas pressures in different pipes. Different gas pressures can affect the flow characteristics of tobacco, thereby affecting the efficiency of mixing and flavoring.

[0029] It should be noted that in order to ensure that the tobacco flows more smoothly during the mixing and flavoring process, and at the same time reduce the tobacco breakage rate caused by friction and collision, the first shell 2 adopts a smooth inner wall design, and does not install partitions and nails and other internal structures that may increase friction, thereby simplifying the flow path of the tobacco, ensuring the integrity of the tobacco, and improving the mixing efficiency of the tobacco in the first shell 2.

[0030] Furthermore, the third shell 5 is provided with a conical shell gas outlet 4 with an opening facing upward, and a cylindrical extended baffle is extended from the end of the conical shell gas outlet 4, and the outlet diameter of the cylindrical extended baffle is smaller than the diameter of the second shell 3, but larger than the diameter of the bottom of the first shell 2. By appropriately reducing the diameter of the conical shell gas outlet 4, the flow path and residence time of the tobacco in the serial two-stage device are extended, which helps the tobacco to mix and absorb the flavor more fully, thereby improving the mixing and flavoring effects.

[0031] Furthermore, the gas pressure at the outlet of the cylindrical extension baffle is lower than the gas pressure at the feed port 8, thereby ensuring that the tobacco in the first shell 2 can smoothly enter the second shell 3 after being flavored, so as to achieve the second step of uniform mixing. In order to prevent the tobacco from entering the gas transport pipeline 10 and improve the uniformity of the fluidized bed airflow, a gas distribution plate 11 is installed at the air inlet of the second shell 3. The gas distribution plate 11 is detachably connected to the gas transport pipeline 10. When the flavor in the first shell 2 enters the second shell 3, it is convenient to clean and maintain the part of the air inlet to prevent the flavor in the first shell 2 from forming a small amount of droplets during the atomization process and entering the air inlet of the second shell 3, thereby causing the attachment of the flavor.

[0032] Furthermore, the flavoring device also includes a flavor storage and pressurizing mechanism 1, which is connected to the atomizing nozzle 9, and the atomizing nozzle 9 is placed in the first shell 2. The flavor storage and pressurizing mechanism 1 is responsible for storing flavors and providing a stable nozzle pressure for the atomizing nozzle 9. By adjusting the nozzle pressure, the atomization degree and spraying range of the flavor can be accurately controlled, thereby ensuring that the tobacco shreds evenly absorb the flavor in the first shell 2, thereby improving the flavoring uniformity and quality of the final tobacco product. Example 2

[0033] See also Figure 2, a serial two-stage tobacco mixing and flavoring method, comprising: Step S1, different types of tobacco are fed into the feed hopper 13 in proportion through the feed conveyor belt 12, and the airflow driven by the blower 15 is used to feed the tobacco into the first housing 2 of the serial two-stage device through the gas transport pipeline 10; Step S2, using the atomizing nozzle 9 built into the first shell 2 to spray the essence on the tobacco to perform a preliminary flavoring process; Specifically, due to the centrifugal force, the tobacco shreds are distributed near the wall of the first shell 2, and the atomizing nozzle 9 located in the first shell 2 evenly adds fragrance to the tobacco shreds in the first shell 2. At the same time, the tobacco shreds are mixed for the first time due to mutual collision and airflow.

[0034] Step S3, sending the flavored tobacco into the third housing 5 in the second housing 3, so that the tobacco is further mixed and fluidized under the action of the airflow conveyed by the gas conveying pipeline 10; Specifically, the tobacco entering the second shell 3 is further mixed under the combined effect of gravity and the airflow in the third shell 5, and due to the presence of the cylindrical extension version of the conical shell air outlet 4, the mixing time is further extended, and the tobacco that is not fully flavored in the first shell 3 can also be flavored during the mixing process.

[0035] Step S4, the mixed and flavored tobacco shreds pass through the discharge port 6 and fall onto the discharge conveyor belt 16, and finally the flavoring and mixing process of the tobacco shreds is completed.

[0036] Furthermore, the change of gas pressure at the air inlet at the bottom of the third housing 5 is adjusted according to different mixing requirements to achieve two operation modes: uniform fluidization and pulse jet fluidization. In the uniform fluidization mode, the gas pressure remains constant to maintain the stable fluidization state of the tobacco, which is suitable for tobacco that requires long-term mixing. In the pulse jet fluidization mode, the gas pressure changes in a pulse form to promote rapid mixing of the tobacco, which is suitable for tobacco that requires rapid mixing or special mixing effects.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
