Humidifier setting method, air-conditioned storage method and storage stack

Abstract

The application relates to the field of tobacco storage and alcoholization, in particular to a humidifier setting method, an air-conditioning storage method and a storage stack. The humidifier setting method comprises the following steps: S1, placing overhead boxes in a spaced manner on the top of a tobacco stack; and S2, placing humidifiers in the space between the overhead boxes. Since the relative molecular mass of water vapor is smaller than that of air, the water vapor evaporated from tobacco can be enriched at the top of the tobacco stack. Overhead boxes are additionally arranged on the top of the tobacco stack to form an overhead layer. Since the overhead boxes are arranged and the top layer of tobacco boxes is isolated by an isolation cover, the surface layer of tobacco in the top layer of tobacco boxes can further avoid competitively absorbing water vapor during the period when the humidifiers absorb the water vapor in the overhead layer, so that most of the water vapor can be absorbed by the humidifiers instead of being absorbed by the surface layer of tobacco in the top layer of tobacco boxes.

Description

Technical Field

[0001] This application relates to the field of tobacco storage and aging, and in particular to a method for setting a humidifier, a controlled atmosphere storage method, and a storage stack. Background Technology

[0002] Currently, in the process of storing and aging tobacco leaves in warehouses, the tobacco leaves are first wrapped in bags with a certain degree of breathability and then stored in tobacco boxes. The tobacco boxes are then stacked to form tobacco stacks. The tobacco stacks are then wrapped in membrane covers, and the oxygen concentration and humidity inside the tobacco stacks are controlled by means of nitrogen replacement and humidifier regulation.

[0003] However, the above solution has the following problems: First, the cost of the bags for loading tobacco leaves is high, and the tobacco leaves must be bagged first and then unpacked before entering the next process, which increases the process cost; Second, the bags can effectively prevent the tobacco leaves from getting damp, but they also affect the efficiency of oxygen exchange between the inside and outside, thus prolonging the time required for the aging of tobacco leaves.

[0004] For the reasons mentioned above, some customers are considering eliminating the bagging of tobacco leaves during the aging process and instead preventing them from getting damp by strengthening humidity control. In response to these customer needs, the applicant developed this technical solution. Summary of the Invention

[0005] To protect the uncovered smoke box from moisture during the aging process, this application provides a method for setting a humidifier, a controlled atmosphere storage method, and a storage stack.

[0006] In a first aspect, this application provides a method for setting a humidifier, employing the following technical solution: A method for setting a humidifier, comprising: S1. Place the overhead boxes on top of the tobacco stack at intervals; S2. Place a humidity regulator in the space between the overhead boxes.

[0007] By adopting the above technical solution, since the relative molecular mass of water vapor is smaller than that of air, the water vapor evaporating from the tobacco leaves will accumulate at the top of the tobacco stack. Previously, when the tobacco stack was sealed, the top surface of the membrane cover was pressed tightly against the surface of the top tobacco box due to gravity. This caused water vapor from the bottom to rise and remain firmly on the surface of the tobacco box. Furthermore, because most of the top surface of the membrane cover was in close contact with the surface of the top tobacco box, it created isolated water vapor islands, resulting in a low rate of water vapor exchange between different locations, preventing the added humectant from quickly absorbing the water vapor. By adding an additional elevated box at the top of the tobacco stack to form an elevated layer, the elevated box and the isolation cover of the top tobacco box create a unified water vapor accumulation area, allowing the humectant to quickly absorb the water vapor from the entire area. Furthermore, it separates the top water vapor accumulation area from the tobacco box, ensuring that most of the water vapor is absorbed by the humectant and not by the surface tobacco leaves of the top tobacco box.

[0008] Preferably, before step S1, an isolation cover is installed on the smoke box at the top of the smoke stack.

[0009] By adopting the above technical solution, an isolation cover is installed on the top-level tobacco box to prevent it from directly contacting and absorbing moisture from the high concentration of water vapor. This further avoids the surface tobacco leaves of the top-level tobacco box competitively absorbing moisture while the humidifier is absorbing moisture from the overhead layer; therefore, the vast majority of the moisture will still be absorbed by the humidifier.

[0010] Secondly, this application provides a controlled atmosphere storage method, which adopts the following technical solution: A controlled atmosphere storage method includes: N1. Laying the base film; N2. Stack the cigarette boxes on the bottom membrane to form a cigarette stack; N3. Place the overhead boxes on top of the tobacco stack with spacing between them; N4. Place a humidity regulator in the space between the overhead boxes; N5. The smoke stack is covered by a top membrane, and the top and bottom membranes are heat-sealed to form an independent space isolated from the outside air.

[0011] By adopting the above technical solution, an independent space isolated from the outside air is formed by heat-sealing the bottom and top films. Moisture will accumulate at the top of the tobacco stack within this independent space. Therefore, an additional overhead box is installed at the top of the stack to form an overhead layer. Due to the overhead box and the isolation of the top tobacco box by the isolation cover, the non-top tobacco boxes and the area where moisture accumulates at the top of the stack are separated by a considerable spatial distance, allowing most of the moisture to be absorbed by the humectant rather than by the tobacco leaves.

[0012] Preferably, after step N2 and before step N3, an isolation cover is installed on the smoke box at the top of the smoke stack.

[0013] By adopting the above technical solution, an isolation cover is installed on the top layer of the smoke box to prevent it from directly contacting and absorbing moisture from the high concentration of water vapor. The second layer of smoke boxes, being relatively far from the moisture-rich area at the top of the smoke stack, will have most of its moisture absorbed by the humidifier.

[0014] Preferably, in step N1, a protective mat layer is first laid on the ground, and then a base film is laid on top of the protective mat layer.

[0015] By adopting the above technical solution, a bedding layer is laid on the ground to separate the bottom layer of tobacco stacks from the ground, thus preventing the rapid cooling of the ground during the transition between day and night from causing condensation and water accumulation at the bottom of the tobacco stacks, which would lead to dampness of the tobacco leaves.

[0016] Thirdly, this application provides a smokestack constructed using the above method, employing the following technical solution: A tobacco stack constructed using the above method includes a tobacco stack formed by stacking multiple tobacco boxes, with multiple overhead boxes on top of the tobacco stack and a humidifier placed between adjacent overhead boxes.

[0017] By adopting the above technical solution, an additional overhead box is set on top of the tobacco stack to form an overhead layer. Due to the setting of the overhead box and the isolation of the top tobacco box by the isolation cover, the non-top tobacco box and the area where water vapor accumulates at the top of the tobacco stack are separated by a large spatial distance, so that most of the water vapor can be absorbed by the humidifier and will not be absorbed by the tobacco leaves.

[0018] Preferably, each tobacco box on the top layer of the tobacco stack is fitted with an isolation cover.

[0019] By employing the above technical solution, the isolation cover prevents the top-level smoke box from directly contacting and absorbing moisture from the high concentration of water vapor. The second-level smoke box, being relatively far from the moisture-rich area at the top of the smoke stack, will have most of its moisture absorbed by the humidifier.

[0020] Preferably, the isolation cover includes a cover body that completely covers the top surface of the cigarette box and partially or completely covers the sides of the cigarette box, and an elastic band disposed on the opening side of the cover body.

[0021] By adopting the above technical solution, the isolation cover is fixed to the cigarette box by elastic band, so the isolation cover does not need to be damaged when unpacking, and it can be recycled to save costs.

[0022] Preferably, the isolation cover is a cover that encloses the entire smoke box.

[0023] By adopting the above technical solution, and instead of using an isolation cover with elastic bands, the entire tobacco box is directly wrapped inside the isolation cover, achieving a better moisture-proof effect.

[0024] Preferably, the overhead box is a cardboard box.

[0025] By adopting the above technical solution, cardboard boxes, used as tobacco storage boxes, can be readily available in warehouses and require no additional preparation. Furthermore, cardboard boxes also possess some water absorption capacity. In summary, this application includes at least one of the following beneficial technical effects: 1. Install an isolation cover on the top layer of the smoke box to prevent the top layer of the smoke box from directly contacting and absorbing water from the high concentration of water vapor.

[0026] 2. By setting up an additional overhead box on top of the tobacco stack to form an overhead layer, the overhead box and the isolation of the top tobacco box by the isolation cover can further prevent the surface tobacco leaves of the top tobacco box from competitively absorbing moisture while the humectant is absorbing moisture in the overhead layer. This allows most of the moisture to be absorbed by the humectant and not by the tobacco leaves. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a method for setting a humidifier, a controlled atmosphere storage method, and a storage stack.

[0031] Example 1: Methods for setting humidifiers include: S1. Install an isolation cover 6 on the top layer of the smoke box 1 of the smoke stack.

[0032] S2. Place the overhead boxes 9 on top of the tobacco stack, spaced apart from each other.

[0033] S3. Place a humidity regulator in the space between the overhead boxes 9.

[0034] Because the relative molecular mass of water vapor is smaller than that of air, the water vapor evaporating from the tobacco leaves tends to accumulate at the top of the tobacco stack. Previously, when the tobacco stack was sealed, the top surface of the membrane cover 3 was pressed tightly against the surface of the top tobacco box 1 under gravity. This caused water vapor from the bottom to rise and remain firmly on the surface of the tobacco box. Furthermore, because most of the top surface of the membrane cover 3 was in close contact with the surface of the top tobacco box, it created isolated water vapor islands. The rate of water vapor exchange between different locations was low, preventing the added humectant from quickly absorbing the water vapor. By installing an isolation cover 6 on the top tobacco box 1, the top tobacco box 1 is prevented from directly contacting and absorbing the high concentration of water vapor. Simultaneously, by adding an additional overhead box 9 at the top of the tobacco stack to form an elevated layer, the water vapor accumulation area becomes a complete region, allowing the humectant to quickly absorb the water vapor from the entire area. Meanwhile, due to the setup of the overhead box 9 and the isolation of the top tobacco box 1 by the isolation cover 6, it is possible to further prevent the surface tobacco leaves of the top tobacco box 1 from competitively absorbing moisture during the absorption of moisture in the overhead layer by the humidifier, so that most of the moisture can be absorbed by the humidifier and not by the tobacco leaves.

[0035] Example 2: Controlled atmosphere storage methods include: N1. Lay a protective mat layer on the ground.

[0036] N2. Lay the bottom film 5 on top of the protective pad.

[0037] N3. Stack the tobacco boxes 1 on the bottom membrane 5 to form a tobacco stack.

[0038] N4. Install an isolation cover 6 on the top layer of the smoke box 1 of the smoke stack.

[0039] N5. Place the overhead boxes 9 on top of the tobacco stack, spaced apart from each other.

[0040] N6. Place a humidity regulator in the space between the overhead boxes 9.

[0041] N7. The smoke stack is covered by the top membrane 4, and the top membrane 4 and the bottom membrane 5 are heat-sealed to form an independent space isolated from the outside air.

[0042] The bottom film 5 and the top film 4 work together to completely cover the tobacco stack, creating an independent space isolated from the outside air, providing the basic conditions for oxygen and humidity control within the stack. An isolation cover 6 is installed on the top tobacco box 1 to prevent it from directly contacting and absorbing moisture from the high concentration of water vapor. Simultaneously, an additional overhead box 9 is installed at the top of the stack to form an elevated layer, creating a complete area where the moisture-rich zone can be quickly absorbed by the humidifier. Furthermore, the overhead box 9 and the isolation cover 6 further prevent the surface tobacco leaves of the top tobacco box 1 from competitively absorbing moisture while the humidifier is absorbing moisture from the elevated layer, ensuring that most of the moisture is absorbed by the humidifier and not by the tobacco leaves, thus guaranteeing the storage quality of the tobacco leaves.

[0043] Example 3: like Figure 1 As shown, a smoke stack constructed using the aforementioned controlled atmosphere storage method includes a stack body 2 formed by stacking multiple smoke boxes 1 and a membrane cover 3 that isolates the entire stack body 2 to form a separate space. The membrane cover 3 includes a top membrane 4 and a bottom membrane 5, with a heat-sealed periphery around the top membrane 4 and the bottom membrane 5.

[0044] like Figure 1 and Figure 2 As shown, each smoke box 1 on the top layer is fitted with an isolation cover 6. The isolation cover 6 includes a cover body 7 with an opening on one side and an elastic band 8 provided on the opening side of the cover body 7. The elastic band 8 is used to tighten the cover on the side or top of the smoke box 1, so that the entire top surface of the smoke box 1 is covered, and the upper half or all sides of the side of the smoke box 1 are covered at the same time.

[0045] like Figure 1 As shown, multiple empty boxes 9 are installed inside the membrane cover 3, located between the top layer of the stack 2 and the top cover. In this application, the empty boxes 9 are preferably cardboard boxes. Adjacent empty boxes 9 are spaced apart from each other, and a desiccant is placed in the isolation space between adjacent empty boxes 9.

[0046] Moisture evaporated from the tobacco leaves accumulates in the space at the top of the tobacco stack. Because the design of the overhead box 9 separates the tobacco box 1 from the top of the stack, and the top tobacco box 1 is covered by the isolation cover 6, the top tobacco box 1 does not absorb moisture. Most of the moisture is absorbed by the humectant and the cardboard box located above the stack 2, effectively preventing the tobacco leaves from becoming damp. Furthermore, since the isolation cover 6 is fixed to the tobacco box 1 by elastic bands 8, it does not need to be damaged during unpacking, allowing for recycling and cost savings.

[0047] Example 4: like Figure 3As shown, a tobacco stack includes a stack body 2 formed by stacking multiple tobacco boxes 1 and a membrane cover 3 that isolates the entire stack body 2 to form a separate space. The membrane cover 3 includes a top membrane 4 and a bottom membrane 5, and the periphery of the top membrane 4 and the bottom membrane 5 is heat-sealed.

[0048] like Figure 3 and Figure 4 As shown, each smoke box 1 on the top layer is fitted with an isolation cover 6, which encloses and seals the entire smoke box 1. Inside the membrane cover 3, located between the top layer of the stack 2 and the top cover, there are multiple overhead boxes 9. Adjacent overhead boxes 9 are spaced apart from each other, and a dehumidifier is placed in the space between adjacent overhead boxes 9.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
