Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf cold storage technology, specifically to a cold storage for preserving cigar tobacco leaves. Background Technology

[0002] The preservation of cigar tobacco leaves involves placing them in a constant temperature, humidity, and dark environment to prevent mold, pests, and off-odors. Regular ventilation and inspection are also necessary to maintain their flexibility, flavor, and promote the natural aging process, ensuring that the quality of the tobacco leaves improves rather than deteriorates over time.

[0003] During the storage of cigar tobacco leaves, the quality stability of the tobacco leaves is highly dependent on the precise control of environmental parameters. Traditional tobacco storage often uses natural ventilation or constant temperature and humidity warehouses, which have problems such as large fluctuations in temperature and humidity and uneven air circulation in local environments. This can easily lead to mold, oil oxidation, or cracking of the tobacco leaves. In addition, the contact between the tobacco leaves and the airflow in the warehouse is passive, and the bottom of the cigar tobacco leaves does not easily come into contact with the airflow. This can easily cause the ammonia and aldehyde gases released during the aging process of the tobacco leaves to not dissipate completely, affecting the later aging flavor of the tobacco leaves and reducing the quality of the tobacco leaves. It is necessary to manually turn the tobacco leaves regularly to avoid the temperature of the bottom of the tobacco leaves being too high, which increases the labor intensity and is less economical.

[0004] Therefore, in order to address the above problems, a cold storage for preserving cigar tobacco leaves is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a cold storage for preserving cigar tobacco leaves. This invention allows for full contact between air and tobacco leaves, preventing mold growth at the bottom of the leaves due to poor air circulation, and thus extending the preservation time of the tobacco leaves.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A cold storage for preserving cigar tobacco leaves includes a storage body comprising a metal frame and multi-layered walls mounted on the metal frame. A moisture-proof layer is installed at the bottom of the storage body, and a circular slide rail is installed on the moisture-proof layer. Multiple shelves slide along the slide rail, and each shelf has multiple shelves with adjustable spacing via a lifting mechanism. The shelves are used to hold cigar tobacco leaves and are equipped with anti-mold and antibacterial components. The system also includes a ventilation system with an air inlet and an exhaust system, respectively located on both sides of the storage body to create a unidirectional gas flow. A temperature and humidity control system includes a refrigeration system and a humidification system. The refrigeration system is located on the side of the storage body closest to the air inlet system, and the humidification system is evenly distributed throughout the storage body. Finally, a safety system includes an alarm system and a fire prevention system, both located within the storage body.

[0008] As a preferred embodiment, the warehouse wall includes a support layer, a heat insulation layer and an inner liner layer. A support layer is provided on both the inner and outer sides of the heat insulation layer, and an inner liner layer is provided on the side of the inner support layer away from the heat insulation layer.

[0009] The moisture-proof layer includes an epoxy resin coating, which is applied to the inner liner at the bottom of the tank. The floor is laid on the epoxy resin coating, and the floor is made of cedar wood.

[0010] Preferably, the slide rail has two rings with the same distance between them, forming a U-shape. The bottom sides of the shelf are connected to different slide rails by pulleys. The shelf slides along the slide rails so that different sides of the shelf can meet the airflow direction.

[0011] Preferably, the lifting assembly includes a threaded rod and a threaded sleeve. The main body of the shelf includes interconnected stainless steel square tubes. Both sides of the shelf are vertically arranged with parallel threaded rods. The threaded rods are threadedly connected to the threaded sleeves. The threaded sleeves are rotatably mounted on the shelf plate. An external gear is coaxially mounted on the threaded sleeve. The external gear meshes with the main gear. The main gear is coaxially mounted at the output end of the lifting power component. The lifting power component is mounted on the shelf plate.

[0012] Preferably, the cargo shelf is made of cedar wood, and side baffles are provided on the sides of the cargo shelf. Several ventilation holes are opened through the cargo shelf and the side baffles. The side cross-section of the cargo shelf is set in a V shape.

[0013] As a preferred option, the anti-mold and antibacterial components include ultraviolet sterilization lamps and antibacterial plates. Multiple ultraviolet sterilization lamps are evenly distributed on the bottom side of the shelf, and the antibacterial plates are detachably mounted on the shelf.

[0014] Preferably, the air intake assembly includes a brushless fan, which is installed on one side of the wall inside the air conditioning unit. The brushless fan is connected to the filter through the air intake pipe and then passes through the wall to communicate with the outside air.

[0015] The ventilation system includes an exhaust fan, which is mounted on the wall opposite the air intake system. The exhaust fan passes through the wall and is connected to the outside air via an exhaust duct.

[0016] Preferably, the humidification component includes several ultrasonic atomizers, which are evenly distributed on the bottom plate inside the warehouse without affecting the movement of the shelves. The ultrasonic atomizers are connected to the pure water supply end through pipes.

[0017] Preferably, the alarm components include an audible and visual alarm and several smoke detectors, and the fire protection components include several sprinkler heads. The smoke detectors and sprinkler heads are evenly distributed on the top of the warehouse, and all sprinkler heads are connected to water pipes.

[0018] Preferably, it also includes control components, including temperature and humidity sensors, which are mounted on the shelf.

[0019] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0020] This invention utilizes a circular slide rail with movable shelves to allow the tobacco leaves on the shelves to change their orientation relative to the airflow within the storage area. This ensures the tobacco leaves are fully exposed to the airflow, preventing excessive temperature differences between different sections caused by prolonged contact with cold air on a single side, which could negatively impact preservation quality. Multiple lifting shelves are installed, and their height on the shelves is adjustable, facilitating the placement and retrieval of tobacco leaves without compromising space utilization and improving efficiency. Furthermore, the V-shaped cross-section of the shelves, along with numerous ventilation holes on the shelves and side panels, allows air flowing within the storage area to enter the bottom of the stacked tobacco leaves through ventilation holes on one side of the V-shaped shelf and exit through ventilation holes on the other side. This effectively removes heat, ammonia, aldehydes, and other gases generated at the bottom of the tobacco leaves due to prolonged storage, preventing them from affecting quality and reducing the need for frequent turning by staff, thus lessening labor intensity.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-6 As shown, this utility model provides a technical solution:

[0031] A cold storage for preserving cigar tobacco leaves includes a storage body 1. The storage body 1 includes a metal frame forming a cubic space and multi-layered storage walls 102 set on the metal frame. The metal frame provides support and is made of aluminum alloy profiles bolted or welded together, making it lightweight, high-strength, and corrosion-resistant. A moisture-proof layer 103 is provided at the bottom of the storage body 1. A circular slide rail 2 is provided on the moisture-proof layer 103, and multiple shelves 3 are slidably mounted on the slide rail 2. Each shelf 3 has multiple layers of display panels 5 slidably mounted on it via a lifting component 4. The distance between adjacent display panels 5 is adjustable. The display panels 5 are used to place cigar tobacco leaves, and the display panels 5 are also equipped with anti-mold and antibacterial components 6 for disinfection. The system includes anti-mold and antibacterial measures for cigar tobacco leaves; a ventilation system comprising an air inlet assembly 7 and an exhaust assembly 8, respectively located on both sides of the storage unit 1, to create a unidirectional gas passage within the storage unit 1, with the direction of the gas passage parallel to the overall length of the slide rail 2; a temperature and humidity control system comprising a cooling assembly 9 and a humidifying assembly 10, with the cooling assembly 9 located on the side of the storage unit 1 closest to the air inlet assembly 7, facilitating the rapid distribution of cold air throughout the storage unit 1 during air intake; and a humidifying assembly 10 evenly distributed throughout the storage unit 1, facilitating simultaneous humidification of different locations within the storage unit 1; and a safety system comprising an alarm assembly 11 and a fireproof assembly 12, located within the storage unit 1 to prevent significant losses in the event of a safety accident.

[0032] In an optional embodiment, the storage wall 102 includes a support layer 1021, a heat insulation layer 1022, and an inner liner layer 1023. A support layer 1021 is disposed on both the inner and outer surfaces of the heat insulation layer 1022. An inner liner layer 1023 is disposed on the side of the support layer 1021 located inside the storage body 1 away from the heat insulation layer 1022. Preferably, the support layer 1021 is made of polyurethane composite board, and the heat insulation layer 1022 is made of vacuum insulation board, which enhances the support and heat insulation properties of the storage wall 102. The inner liner layer 1023 is made of food-grade stainless steel plate with a smooth surface and is mold-proof. The moisture-proof layer 103 includes an epoxy resin coating. 1031, an epoxy resin coating is applied to the inner liner layer 1023 at the bottom of the storage body 1. A floor 1032 is laid on the upper side of the epoxy resin coating 1031. The floor 1032 is made of cedar wood. A storage door 101 is opened on the storage wall 102 on the side of the storage body 1 near the exhaust component 8. The storage door 101 is equipped with a horizontally sliding door. Preferably, the door and the storage wall 102 have the same heat insulation effect. A magnetic sealing strip is set on the edge of the door to enhance the sealing effect. The storage door 101 is located on the storage wall 102 on the side near the exhaust component 8, which is the downwind vent. This can minimize the possibility of impurities brought into the storage body 1 by personnel coming into contact with the tobacco leaves, thus improving practicality.

[0033] In an optional embodiment, the slide rail 2 has two annular sections, with the two slide rails 2 being equidistant from each other, forming a U-shape. Specifically, the U-shape is a straight section in the middle and a semi-circular arc shape at both ends, facilitating turning when the shelf 3 moves. The bottom sides of the shelf 3 are connected to different slide rails 2 by pulleys that slide or roll. The pulleys are connected to a power motor, enabling the shelf 3 to move automatically. When turning, the pulleys on the inner and outer slide rails 2 have different speeds, with the inner speed decreasing and the outer speed increasing, to achieve stable turning of the shelf 3 and prevent derailment. The sliding of the shelf 3 along the slide rail 2 allows different sides of the shelf 3 to meet the airflow direction. At the same time, the movement of the shelf 3 can also agitate the air inside the storage body 1, accelerating the rapid distribution of cold and humid air into the space inside the storage body 1, preventing the storage body 1 from being too humid or too cold, while saving costs and improving economic efficiency.

[0034] In an optional embodiment, the lifting assembly 4 includes a threaded rod 401 and a threaded sleeve 402. The main body of the shelf 3 includes interconnected stainless steel square tubes. Threaded rods 401 are vertically arranged on both sides of the shelf 3, and threaded sleeves 402 are threadedly connected to the threaded rods 401. The threaded sleeves 402 are rotatably mounted at both ends of the shelf 5. An external gear 403 is coaxially mounted on the threaded sleeve 402, and the external gear 403 meshes with a main gear 404. The main gear 404 is coaxially mounted at the output end of the lifting power component 405. The lifting power component 405 is mounted on the shelf 5 and can be a small motor. Each small motor on the shelf 5 is connected to the same switch, which controls the forward and reverse rotation of the small motor. The other end of the switch is connected to a battery to control the lifting of the shelf 5.

[0035] In an optional embodiment, the shelf 5 is made of cedar wood, and a side baffle 406 is provided on the side of the shelf 5 to prevent tobacco leaves from falling during the movement of the shelf 3. Several ventilation holes 407 are opened through the shelf 5 and the side baffle 406 to facilitate air circulation. The side cross section of the shelf 5 is set in a V shape to reserve ventilation space at the bottom of the tobacco leaves, which facilitates air circulation at the bottom of the tobacco leaves and improves the quality of tobacco leaf preservation.

[0036] In an optional embodiment, the anti-mold and antibacterial component 6 includes an ultraviolet sterilization lamp 601 and an antibacterial plate 602. Multiple ultraviolet sterilization lamps 601 are evenly distributed on the bottom side of the shelf 5 for timed sterilization. For the top layer of tobacco leaves, an ultraviolet sterilization lamp 601 is also installed below the top plate of the shelf 3 to avoid omissions. Since tobacco leaves cannot be exposed to ultraviolet light for a long time, the ultraviolet sterilization lamp 601 is turned on only twice a day, each time for no more than ten minutes. The antibacterial plate 602 is detachably installed on the shelf 3. The antibacterial plate 602 is a metal plate coated with a nano-silver antibacterial coating and is installed on the bottom plate of the shelf 3.

[0037] In an optional embodiment, the air intake assembly 7 includes a brushless fan, which is mounted on the wall 102 on one side of the storage chamber 1. The brushless fan is connected to the outside air through the air intake pipe and then through the wall 102. The filter is a HEPA filter. Preferably, an activated carbon filter is also installed in the air intake pipe to remove any odors that may be present in the outside air and to prevent a decrease in the quality of the tobacco leaves. The exhaust assembly 8 includes an exhaust fan, which is mounted on the wall 102 opposite to the air intake assembly 7. The exhaust fan is connected to the outside air through the exhaust pipe and then through the wall 102 to exhaust the gas inside the storage chamber 1. Preferably, the outlet of the exhaust pipe at the outer end of the storage chamber 1 faces the ground to prevent backdraft and rainwater backflow, thus improving practicality.

[0038] In an optional embodiment, the humidification assembly 10 includes a plurality of ultrasonic atomizers 1001. The ultrasonic atomizers 1001 are evenly distributed on the bottom plate inside the warehouse 1 without affecting the movement of the shelf 3. The ultrasonic atomizers 1001 are connected to the pure water supply end through pipes to humidify the space in different locations inside the warehouse 1 at the same time, thereby improving efficiency.

[0039] The refrigeration component 9 can adopt a conventional refrigeration scheme or air conditioning refrigeration. Its specific structure and connection relationship are not the subject matter to be protected by this utility model, so they will not be described in detail. It is only necessary to set the refrigeration component 9 on the wall 102 of the storage room near the air inlet component 7 and above the air inlet component 7. By the sinking of cold air and the cooperation of the air inlet component 7, the cold air fills the storage room 1, which improves the economy.

[0040] In an optional embodiment, the alarm component 11 includes an audible and visual alarm 1101 and several smoke detectors 1102, and the fire prevention component 12 includes several sprinkler heads. The smoke detectors 1102 and sprinkler heads are evenly distributed on the top of the storage body 1, and the sprinkler heads are all connected to water pipes. Since there are flammable materials such as wooden boards in the storage body 1, a safety system is set up to take into account the possibility of fire. The audible and visual alarm 1101, smoke detectors 1102 and sprinkler heads are all selected from commonly available models on the market, which is more economical.

[0041] In an optional embodiment, a control component is also included, comprising multiple temperature and humidity sensors evenly distributed at different positions and heights on the shelf 3. By detecting the temperature and humidity in the air near the tobacco leaves, it is determined whether the tobacco leaves need to be cooled or humidified. The temperature is controlled between 18°C ​​and 22°C, and the relative humidity is controlled between 65% and 70%, which improves the accuracy of detection.

[0042] Working principle: First, tobacco leaves are placed on the storage plates 5, with the thickness of the tobacco leaves stacked on each storage plate 5 not exceeding 15 cm to avoid excessive internal temperature and reduced quality due to overly thick stacking. While placing the tobacco leaves, the height of the storage plates 5 is adjusted so that the distance between adjacent storage plates 5 is not less than 20 cm to facilitate air circulation. Then, based on the measurement data from temperature and humidity sensors, it is determined whether cooling or humidification is needed. If cooling or humidification is required, the cooling component 9, air intake component 7, humidification component 10, and exhaust component 8 are activated. Simultaneously, the shelf 3 is moved so that different sides of the shelf 3 are aligned with the direction of airflow, improving efficiency. The cooling and humidification speed of tobacco leaves on different shelves 3 is preferably such that when the shelf 3 moves, it moves 180° clockwise around the slide rail 2 to achieve left-right repositioning. When it moves again, the shelf 3 moves 180° counterclockwise around the slide rail 2 to return to its original position. When there are wires connected to the shelf 3, it can avoid the wires from getting tangled. At the same time, the shelf 3 itself can stir the air in the storage room 1, accelerate the mixing of new air and old air, improve efficiency, and reduce economic costs. When cooling and humidification are not required, but timed ventilation is still needed, only the air intake component 7 and the exhaust component 8 are turned on, and then the shelf 3 is moved to accelerate the exchange of air in the storage room 1, which ensures the quality of tobacco leaves and extends the storage time, making it more practical.
