Description

Technical Field

[0001] The present application relates to the technical field of cigar drying, and in particular to a three-dimensional flat-layer convection drying system for cigar tobacco leaves. Background Art

[0002] During the drying process of cigar tobacco leaves, there are withering period, yellowing period, browning period, color fixing period, dry tendon period and other periods. Temperature and humidity control is very important for the changes of tobacco leaves. Traditional cigar drying rooms usually mount cigar tobacco leaves in a room 5-6 meters high, and then control the temperature, humidity, ventilation and other conditions of the cigar tobacco leaves in the entire drying room to allow the cigar tobacco leaves to be dried within the complete drying cycle. However, in traditional drying rooms, the temperature and humidity control is relatively simple, and the mounting and disassembly are relatively troublesome. With the advancement of technology, drying rooms with intelligent backgrounds have gradually emerged. Cameras and sensors can be set in the drying rooms to detect the changing status of tobacco leaves in the drying rooms in real time, and make real-time adjustments for abnormal situations. However, since the cigar tobacco leaves are kept at a uniform temperature and humidity throughout the drying room, the temperature changes too directly during the drying process of the cigar tobacco leaves, resulting in a compromised taste. At the same time, the height of the drying room is relatively high, and the cigar tobacco leaves located on the upper floors are difficult to mount, and manual mounting may face dangers. In addition, the planting area of ​​cigar tobacco leaves is generally not too large, and the volume of traditional drying rooms is usually relatively large. Small batches of cigar tobacco leaves are usually unable to fill the entire drying room when dried in traditional drying rooms, and energy waste is inevitable during the drying process. Therefore, it is urgent to provide a new cigar tobacco leaf drying system to solve the current problems. Summary of the invention

[0030] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiment is only one embodiment of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] "Embodiment" referred to herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present application. In the description of the embodiment of the present application, it should be understood that the terms "first", "second" and "third" etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" etc. may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second" and "third" etc. are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiment of the present application described here can be implemented in an order other than illustrated or described here. In addition, the terms "including" and "for" and any of their variations are intended to cover non-exclusive inclusions.

[0032] like Figure 1-2 As shown, the present embodiment provides a three-dimensional flat-layer convection drying system for cigar tobacco leaves, comprising a drying room 1, a heating and humidifying device 2 and a lifting device 3. A drying space for accommodating cigar tobacco leaves is arranged in the drying room 1. In the present embodiment, there are five drying stages of cigar tobacco leaves, namely, wilting stage, yellowing stage, browning stage, color fixing stage and dry tendon stage. In order to match the five drying stages of cigar tobacco leaves, the space in the drying room 1 is divided into five drying chambers, namely, the first drying chamber, the second drying chamber, the third drying chamber, the fourth drying chamber and the fifth drying chamber from bottom to top. The five drying chambers are connected from top to bottom, and cigar tobacco leaves can be hung in the five drying chambers respectively.

[0033] In order to ensure that the temperature of cigar tobacco leaves can be precisely controlled in each drying chamber, in this embodiment, each drying chamber is configured with five temperature zones according to the five stages of cigar tobacco leaf drying, namely, a first temperature zone corresponding to the temperature and humidity of the wilting period, a second temperature zone corresponding to the temperature and humidity of the yellowing period, a third temperature zone corresponding to the temperature and humidity of the browning period, a fourth temperature zone corresponding to the temperature and humidity of the color fixing period, and a fifth temperature zone corresponding to the temperature and humidity of the drying period. Cigar tobacco leaves can be dried in any of the five temperature zones in any drying chamber.

[0034] Compared with the traditional drying method in which the temperature of the drying room is always uniform, the drying system provided by the present application only needs to use a lifting device to move the cigar leaves from one drying chamber to the next when a small batch of cigar leaves need to be dried, and then new cigar leaves can be mounted in the empty drying chamber, thereby ensuring the continuity of the drying and at the same time ensuring that the cigar leaves can have precise temperature control at each stage.

[0035] In order to be able to gradually move the cigar tobacco leaves from the first drying chamber to the fifth drying chamber from bottom to top, a lifting device 3 is arranged in the drying room 1 in this embodiment. The cigar tobacco leaves carried by the lifting device 3 can be moved from the first drying chamber to the fifth drying chamber. When the lifting device 3 carries the cigar tobacco leaves and moves them to each drying chamber, the cigar tobacco leaves can be dried using the temperature and humidity from the first temperature zone to the fifth temperature zone.

[0036] like Figure 3-4 As shown, the lifting device 3 includes a chain transmission mechanism 31 arranged in the air-drying cavity, the chain transmission mechanism 31 is arranged close to the side of the air-drying room 1, and passes through the first air-drying cavity, the second air-drying cavity, the third air-drying cavity, the fourth air-drying cavity and the fifth air-drying cavity from bottom to top, and a mounting portion 32 is arranged on the chain transmission mechanism 31, and a mounting block 33 is mounted on the mounting portion 32. In this embodiment, the mounting portion 32 is a fixed block fixed to the chain transmission mechanism 31, and an axial hole is arranged on the fixing block, and a pin is arranged on the mounting block 33, and the pin is installed in the axial hole to realize the mounting block 33 and the mounting portion The rotation connection of 32 ensures that the mounting block 33 is always vertically downward; a mounting hole is opened in the vertical direction on the mounting block 33, and a guide rod 34 is installed in the mounting hole. The guide rod 34 passes through the mounting block in the vertical direction, and a hanging rod mounting hole is provided at the upper end of the guide rod 34. A counterweight block 36 is provided at the other end of the guide rod 34. In this embodiment, a pair of guide rods 34 are arranged opposite to each other in the transverse direction, and a pair of guide rods 34 are respectively provided with hanging rod mounting holes 35. A hanging rod is provided between the pair of hanging rod mounting holes 35. Cigar leaves are hung on the hanging rod, and the counterweight block 36 drives the cigar leaves to always be vertically downward.

[0037] A set of flat air convection system 4 is provided in each of the air-drying chambers. The flat air convection system 4 includes ventilation holes 41 and ventilation equipment provided on opposite sides of the air-drying chamber. The ventilation equipment can conduct the airflow in a pair of ventilation holes 41. The heating and humidifying device 2 is connected to an atomizing device, which provides moisture and humidity to the air-drying chamber. The ventilation equipment heats the moisture atomized by the atomizing device and applies it to the cigar leaves. At the same time, the airflow in the air-drying chamber where the cigar leaves are located is conducted. In order to further improve the balance of temperature and humidity, the distance between two adjacent air-drying chambers is set to 0.5m-1.5m in this application, which basically matches the length of the cigar leaves, that is, a layer of cigar leaves is dried in the vertical direction in each air-drying chamber.

[0038] A cigar drying process provided in this embodiment includes the following steps:

[0039] S1: a lifting device is arranged in the air-drying chamber, and the first batch of cigar tobacco leaves are hung in the lifting device. The lifting device carries the first batch of cigar tobacco leaves and places them in the first air-drying chamber, and air-drying the first batch of cigar tobacco leaves in the first temperature zone for the first time T1;

[0040] Specifically, the first batch of cigar tobacco leaves are hung on the hanging rod 36, and the cigar tobacco leaves are moved to the first airing chamber by the lifting device 3. The temperature of the first temperature zone in the first airing chamber is controlled at 28°C-30°C, and the humidity is controlled at 85%-90%. The airing time is 4 days. In the first temperature zone, the cigar tobacco leaves gradually change from green leaves to wilted and collapsed. The cigar airing system provided in this embodiment can accurately control the temperature and humidity of the cigar tobacco leaves in the first airing chamber through the heating and humidification device 2, and then ventilate the cigar tobacco leaves in the first airing chamber through the flat air convection system, and set the airing temperature, humidity and airing time of the first airing chamber according to the airing stage of the cigar through the cigar airing system.

[0041] S2: The lifting device carries the first batch of cigar tobacco leaves in the first airing chamber and lifts them to the second airing chamber, and airs them in the second temperature zone in the second airing chamber until the second time T2;

[0042] Specifically, the lifting device 3 can smoothly lift the cigar tobacco leaves in the first air-drying chamber upward to the second air-drying chamber after completing the air-drying requirements of the withering period. The second air-drying chamber is located above the first air-drying chamber in the vertical direction. The temperature of the second temperature zone in the second air-drying chamber is controlled to 29°C-33°C by the heating and humidification equipment 2, and the humidity is controlled to 85%-90%. The cigar tobacco leaves are dried in the second temperature zone in the second air-drying chamber for 6 days. In the second air-drying chamber, the cigar tobacco leaves gradually enter the yellowing period from the wilting period, during which the green color of the tobacco leaves fades, and the tobacco leaves turn yellow and soften. Although the second temperature zone is connected to the first temperature zone in space, the temperature and humidity can be precisely controlled separately.

[0043] In another embodiment of the application, when the cigar tobacco leaves carried by the lifting device 3 in the first drying chamber are about to complete the drying requirements of the withering period, the temperature of the first drying temperature zone is adjusted by the thermal humidification device 2 to be further close to but not reaching the second drying temperature zone. Specifically, if the temperature and humidity can be gradually adjusted and smoothly transitioned during the drying process of the cigar tobacco leaves, the taste of the drying will be better. In this embodiment, a transition temperature zone scheme is proposed, that is, after the cigar tobacco leaves in the designated drying chamber are dried in the current drying temperature zone for a preset time, the current drying temperature zone is adjusted to a transition temperature zone, and after the drying time of the cigar tobacco leaves in the current stage is met, the transition temperature zone is adjusted to the drying temperature zone of the next drying stage.

[0044] Taking the cigar tobacco leaves that are air-dried in the withering period as an example, the cigar tobacco leaves are air-dried in the first temperature zone for 4 days in the withering period. When the cigar air-drying system detects that the cigar tobacco leaves in the first temperature zone have been aired for 3 days and are close to completing the air-drying requirements of the withering period, the first temperature zone is adjusted to a transition temperature zone. The temperature and humidity of the transition temperature zone are between the first temperature zone and the second temperature zone, that is, the temperature of the transition temperature zone is higher than the temperature of the first temperature zone and lower than the temperature of the second temperature zone. Providing a transition temperature zone during the transition of the cigar tobacco leaves from the first temperature zone to the second temperature zone can make the air-drying process of the cigar tobacco leaves more in line with the law of natural temperature changes and have a better taste. After the transition temperature zone reaches the specified time, the lifting device 3 carries the cigar tobacco leaves to move to the next air-drying chamber.

[0045] S3: The second batch of cigar tobacco leaves is added to the lifting device in the first airing chamber. After the second batch of cigar tobacco leaves are aired in the first airing chamber for T2 time, the first airing chamber is adjusted to the second temperature zone. After the second batch of cigar tobacco leaves are aired in the first airing chamber for T2-T1 time, they are carried by the lifting device into the second airing chamber;

[0046] In this embodiment, the cigar tobacco leaves are aired in the first temperature zone in the first airing chamber for 4 days, and in the second temperature zone in the second airing chamber for 6 days. After the first batch of cigar tobacco leaves have been aired in the second airing chamber for 4 days, the airing temperature zone of the second batch of cigar tobacco leaves in the first airing chamber needs to be consistent with the airing temperature zone of the cigar tobacco leaves in the second airing chamber. The cigar airing system provided in this embodiment detects that the second batch of cigar tobacco leaves in the first airing chamber have been aired for 4 days, and adjusts the first temperature zone in the first airing chamber to the second temperature zone.

[0047] S4: the lifting device carries the first batch of cigar tobacco leaves in the second airing chamber to the third airing chamber, and airs the first batch of cigar tobacco leaves in the third airing chamber in the third temperature zone for a third time T3;

[0048] At this time, the first batch of cigar tobacco leaves are aired in the third temperature zone in the third airing chamber and gradually enter the browning stage. The surface of the tobacco leaves is yellowish brown to dark brown. The temperature of the third temperature zone is 34°C-36°C, and the humidity is 60%-85%. The first batch of cigar tobacco leaves are aired in the third temperature zone in the third airing chamber for 10 days. In this embodiment, in order to further improve the airing effect of cigar tobacco leaves, the third airing chamber is divided into two temperature zones for airing, which are respectively aired at a temperature of 34°C-36°C and a humidity of 80%-85% in the early stage of browning for 4 days, and then the humidity can be reduced to 60%-70% for airing for 6 days when entering the color fixing stage. The cigar tobacco leaves thus aired have a better taste.

[0049] S5: The lifting device carries the second batch of cigar tobacco leaves in the first air-drying chamber and lifts them to the second air-drying chamber, and air-dries them in the second temperature zone in the second air-drying chamber for a time period of T2-(T2-T1);

[0050] Since the second batch of cigar tobacco leaves currently in the second airing chamber have been aired in the first airing chamber at the second temperature zone for a period of (T2-T1), the time for which the second batch of cigar tobacco leaves currently entering the second airing chamber have been aired in the second temperature zone is T2-(T2-T1), and since the third airing chamber needs to be aired in the third temperature zone for 10 days, while the second batch of cigar tobacco leaves in the second airing chamber only needs to be aired in the second temperature zone for 4 days, after the cigar airing system of this embodiment detects that the second batch of cigar tobacco leaves in the second airing chamber have been aired in the second temperature zone for 4 days, the temperature zone in the second airing chamber is adjusted to the third temperature zone; the airing time for the second batch of cigar tobacco leaves in the second airing chamber at the third temperature zone is T3-(T2-(T2-T1)).

[0051] S6: The lifting device carries the first batch of cigar tobacco leaves from the third air-drying chamber to the fourth air-drying chamber, and air-drys them in the fourth temperature zone for a fourth time T4 in the fourth air-drying chamber;

[0052] Specifically, the first batch of cigar tobacco leaves gradually enter the color fixing period in the fourth temperature zone of the fourth air-drying chamber: the temperature of the fourth temperature zone is controlled at 38°C-40°C, the humidity is controlled at 30%-40%, and the air-drying time is 9 days. In the fourth temperature zone, the color of the first batch of cigar tobacco leaves gradually turns dark brown, the side veins are completely dry, and the main veins are dry to 70%;

[0053] S7: the lifting device carries the second batch of cigar tobacco leaves in the second air-drying chamber and lifts them to the third air-drying chamber. After air-drying them in the third temperature zone for a time period of T3-(T3-(T2-(T2-T1))) in the third air-drying chamber, the third temperature zone in the third air-drying chamber is adjusted to the fourth temperature zone;

[0054] At this time, after the second batch of cigar tobacco leaves in the second drying chamber are dried in the third temperature zone for T3-(T2-(T2-T1)) time, they enter the third drying chamber through the movement of the lifting device 3, and continue to be dried in the third temperature zone in the third drying chamber. After detecting that the cigar tobacco leaves have been dried in the third temperature zone in the third drying chamber for T3-(T3-(T2-(T2-T1))) time, the cigar drying system adjusts the third temperature zone in the third drying chamber to the fourth temperature zone, and dries the cigar tobacco leaves in the third drying chamber for T4-(T3-(T3-(T2-(T2-T1)))) time.

[0055] S8: The lifting device carries the first batch of cigar tobacco leaves from the fourth air-drying chamber to the fifth air-drying chamber, and air-dries the cigar tobacco leaves in the fifth temperature zone for the fifth time T5, thereby completing the air-drying of the cigar tobacco leaves;

[0056] Specifically, the first batch of cigar tobacco leaves are aired in the fifth temperature zone in the fifth air-drying chamber and gradually enter the dry-tough stage. During the dry-tough stage, the main veins of the first batch of cigar tobacco leaves gradually dry out, the depressions turn black, and they are easy to break, meeting the requirements for shipment. The temperature in the fifth temperature zone is controlled at 42°C-45°C, the humidity is maintained at 15%-20%, and the air-drying time is 20 days.

[0057] S9: the lifting device carries the second batch of cigar tobacco leaves in the third air-drying chamber and lifts them to the fourth air-drying chamber. After air-drying them in the fourth air-drying chamber at the fourth temperature zone for T4-(T4-(T3-(T3-(T2-(T2-T1)))))), the fourth temperature zone in the fourth air-drying chamber is adjusted to the fifth temperature zone;

[0058] Specifically, the second batch of cigar tobacco leaves in the third drying chamber have been dried in the fourth temperature zone for T4-(T3-(T3-(T2-(T2-T1)))) time. Therefore, when entering the fourth drying chamber, the cigar drying system detects that the second batch of cigar tobacco leaves have been dried in the fourth temperature zone in the fourth drying chamber for T4-(T4-(T3-(T3-(T2-(T2-T1))))) time, and then adjusts the temperature zone in the fourth drying chamber to the fifth temperature zone, and after drying in the fourth drying chamber for T5-(T4-(T4-(T3-(T3-(T2-(T2-T1)))))) time, the cigar drying system is promoted to the fifth drying chamber, and completes drying in the fifth drying chamber. After the first batch of cigar tobacco leaves and the second batch of cigar tobacco leaves are dried in the fifth drying chamber, they are carried out of the cigar drying chamber by the lifting device 3. In this embodiment, after moving from one drying chamber to the next drying chamber, the first drying chamber will be supplemented with cigar tobacco leaves to be dried. The above method is used for cyclic drying, which greatly improves the drying efficiency.

[0059] By adopting the scheme provided in this embodiment, the cigar airing chamber is divided into multiple airing stages according to the airing stages of the cigar tobacco leaves. The cigar tobacco leaves are carried into each airing chamber by the lifting device 3. At the same time, five airing temperature zones are respectively arranged in each airing chamber. The cigar tobacco leaves are aired in sequence in each airing chamber according to the temperature zones required for the airing stages of the cigar tobacco leaves, which well matches the airing conditions required for each stage of the cigar tobacco leaves. The airing temperature zones that were originally constant in the airing chamber are changed into airing temperature zones that can be adjusted separately in each airing chamber, and space is exchanged for time. The traditional temperature time is converted into the length of the temperature zone. At the same time, the airing process of the cigar tobacco leaves is changed from node adjustment to gradual adjustment. The adjustment method is more moderate and more suitable for the changes in tobacco leaf substances. The lifting device carries the cigar tobacco leaves from bottom to top for airing one by one, which conforms to the natural temperature and humidity changes of the cigar tobacco leaves.
