Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf re-drying technology, and in particular to a device for rapid re-softening of selected tobacco leaves. Background Technology

[0002] Tobacco leaf sorting is divided into loose leaf sorting and fine leaf sorting. Loose leaf sorting involves opening the tobacco pack (bundle), loosening the tobacco leaves, and selecting each leaf individually according to the standard sample or customer classification requirements, removing any unsightly, moldy, or impurities, and then categorizing the leaves into different types. Fine leaf sorting involves opening the tobacco pack (bundle), loosening the tobacco leaves, and then selecting each leaf individually according to the standard sample or customer classification requirements, removing any unsightly, moldy, or impurities, and then categorizing the leaves into different types. Both loose and fine leaf sorting require loosening the tobacco leaves. During this loosening process, if the tobacco leaves have low toughness, they will break apart. The lower the toughness, the greater the breakage, and the higher the loss of tobacco leaves during sorting. Existing technologies, in order to reduce leaf breakage during leaf selection and improve tobacco leaf toughness, have proposed a patent entitled "A Tobacco Leaf Re-softening and Humidification Room" (publication number CN217986652U). This patent uses a water vapor rapid dispersion unit to quickly distribute external steam from outside the storage room into the storage room, maintaining a certain humidity level inside the storage room and allowing the tobacco leaves to maintain a certain softness and moisture. However, the re-softening efficiency is low. Existing technologies have also proposed adding heating and humidification devices to the tobacco leaf warehouse, combined with an intelligent temperature and humidity control system, to achieve re-humidification of original tobacco bales and whole frames of tobacco leaves in a sealed space. The re-humidification time is 8 hours per cycle, and only the surface tobacco leaves can be re-softened. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a rapid re-softening device for sorted tobacco leaves, so as to solve the technical problems of low re-softening efficiency, long time and only partial re-softening of existing tobacco leaves.

[0004] The objective of this utility model is achieved through the following technical solution: A rapid softening device for sorting tobacco leaves includes a sorting workbench, the workbench having a table surface with a plurality of air holes distributed thereon, a steam pipe under the table surface, an atomizing nozzle on the steam pipe, and the steam pipe being connected to a steam supply system.

[0005] Furthermore, a debris collection trough is provided under the platform, and the steam pipe is located in the upper middle part of the debris collection trough.

[0006] Furthermore, the steam supply system is a steam generator.

[0007] Furthermore, the steam evaporator includes a heating tank, a heating tube inside the heating tank, a safety valve and a pressure controller on the heating tank, the heating tank being connected to a water source via a pipe and a booster pump, a temperature sensor being installed under the platform, and the pressure controller, temperature sensor, heating tube and booster pump being connected to a controller.

[0008] Furthermore, the diameter of the pores is 6.35 mm.

[0009] Furthermore, the steam pipes are multiple, spaced apart along the width of the platform, and connected to the steam supply system via a main pipe. Each steam pipe has multiple atomizing nozzles evenly spaced along its length.

[0010] The beneficial effects of this utility model are: The proposed rapid softening device for tobacco leaves involves removing a portion of the tobacco leaves from the tobacco bale and placing them on a work surface. The steam supply system sprays steam onto the work surface through steam pipes and atomizing nozzles. The steam passes through several air holes, heating and humidifying the tobacco leaves on the work surface for 10-30 seconds, increasing the toughness of the tobacco leaves and loosening and sorting them. This significantly reduces breakage. Compared to existing technologies, this device achieves close-range, small-volume softening of tobacco leaves with high softening efficiency, speed, and more comprehensive softening. It also reduces the waiting time for loosening and sorting and minimizes heat loss.

[0011] The debris collection trough can collect debris that falls from several pores.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0018] Example 1 like Figure 1-3 The shown rapid softening device for sorting tobacco leaves includes a sorting worktable. The worktable comprises four support legs 1 and a rectangular platform 2 supported by the four support legs 1. Three of the four support legs 1 are connected sequentially by connecting rods 3 to increase the strength of the support. The side without connecting rods 3 is located on the longitudinal side of the rectangular platform 2. This sorting worktable can be used with a stool, allowing the sorting personnel to sit on the stool with their legs extended under the platform 2. The platform 2 has several evenly spaced air holes 4 with a diameter of 6.35 mm to prevent debris from clogging the air holes. Multiple steam pipes 5 are evenly spaced along the width of the platform 2. Each steam pipe 5 has multiple atomizing nozzles 6 evenly spaced along its length. The diameter of the steam pipes 5 is DN15, and the atomizing nozzles 6 are LNN spray heads. The multiple steam pipes 5 are connected to a main pipe 7, which is equipped with a valve. The main pipe 7 is connected to a steam supply system. The steam supply system can be the factory's own steam supply equipment or a self-made steam generator 8. The self-made steam generator 8 includes a heating tank, which is located on the side of the platform 2 away from the stool. The heating tank is a 20L stainless steel tank with a heating tube inside. The heating tube is a 220V, 2KW electric heating tube. The heating tank is equipped with a safety valve and a pressure controller. The safety valve is a spring-loaded safety valve, and the pressure controller is an electronic pressure controller. The heating tank is connected to a water source through pipes and a booster pump. A temperature sensor is located under the platform. The pressure controller, temperature sensor, heating tube, and booster pump are connected to the controller. This steam generator 8 produces 5kg / h of steam. The tabletop 2 is provided with a debris collection trough 9. The steam pipe 5 is located above the debris collection trough 9. The debris collection trough 9 is provided with a debris discharge outlet, which is equipped with an openable and closable door.

[0019] The proposed rapid softening device for tobacco leaves involves removing a portion of the tobacco leaves from the tobacco bale and placing them on a table 2. A steam supply system sprays steam onto the table 2 through steam pipes 5 and atomizing nozzles 6. The steam passes through several air holes 4, heating and humidifying the tobacco leaves on the table 2 for 10-30 seconds, increasing their resilience and facilitating loosening and sorting. This significantly reduces breakage. Compared to existing technologies, this device achieves close-range, small-volume softening of tobacco leaves with high efficiency, speed, and more comprehensive softening. It also minimizes the waiting time for loosening and sorting and reduces heat loss. A debris collection trough 9 collects debris that falls through the air holes.
