Description

Technical Field

[0001] This utility model relates to the field of tobacco curing barn technology, specifically to a cold storage and curing barn combination system. Background Technology

[0002] Tobacco curing is a method of processing tobacco leaves in a specialized curing barn by using heating and ventilation to regulate the temperature and humidity. After curing, the tobacco leaves need to be stored in a constant-temperature and humidity refrigerated environment to improve their quality.

[0003] CN220607314U discloses a multi-functional machine integrating roasting and refrigeration. It is equipped with a rotating drum for roasting tobacco leaves and a refrigeration box for refrigerating tobacco leaves in the roasting room. After the rotating drum finishes roasting the tobacco leaves, the tobacco leaves are discharged from its discharge port and pushed into the refrigeration box by the pusher plate. This method allows the tobacco leaves to be stored in the refrigeration box at a constant temperature and humidity, ensuring that the tobacco leaves will not be dried out while waiting for other tobacco leaves to be processed, thus preventing them from becoming of poor quality.

[0004] However, the rotating drum for roasting tobacco leaves in this patent requires heat, and the refrigeration chamber also requires electricity for cooling, resulting in relatively high energy consumption. Utility Model Content

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a combined system of cold storage and drying room, including:

[0008] The main components include a drying oven and a cold storage room. The drying oven is equipped with a heating chamber and a drying chamber. The heating chamber has an air inlet and an air outlet, and the air outlet is connected to the drying chamber.

[0009] A refrigeration assembly for refrigeration, having an evaporator and a condenser connected together, the evaporator being located inside the cold storage, and the condenser being located at the air inlet and capable of exchanging heat with air entering the heating chamber from the air inlet.

[0010] In some embodiments, the drying chamber further includes a dehumidification channel and an air inlet channel, wherein the dehumidification channel connects the drying chamber to the outside, and the air inlet channel connects the air inlet to the outside;

[0011] The main component also includes a heat-conducting structure, which is disposed between the dehumidification channel and the air inlet channel, so that the air in the dehumidification channel can exchange heat with the air in the air inlet channel.

[0012] In some embodiments, the dehumidification channel has a dehumidification section and a connecting section. The dehumidification section, the air inlet channel, the heating chamber, and the drying chamber are arranged in sequence. One end of the dehumidification section is connected to the outside, and the other end is connected to the drying chamber via the connecting section.

[0013] In some embodiments, the dehumidification section extends in the same direction as the air inlet channel;

[0014] The heat-conducting structure is located between the dehumidification section and the air inlet channel.

[0015] In some embodiments, one end of the dehumidification section that connects to the outside and one end of the air inlet channel that connects to the outside are located on the same side of the drying oven, the connecting section and the air inlet are located on the same side of the drying oven, and the end of the dehumidification section that connects to the outside is located on opposite sides of the drying oven.

[0016] In some embodiments, the heat-conducting structure includes a plurality of heat-conducting fins, which are disposed between the dehumidification section and the air inlet channel and are arranged sequentially along the extension direction of the dehumidification section.

[0022] In some embodiments, the cold storage facility includes a refrigeration room and a freezer room, with the freezer room located inside the refrigeration room.

[0023] Compared with the prior art, the cold storage and drying room combination system provided by this utility model places the evaporator of the refrigeration component in the cold storage. The liquid refrigerant in the evaporator absorbs heat during the process of converting into a gaseous state to achieve refrigeration of the cold storage.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] To address the issue that existing technologies require heat for the tobacco curing drum and also consume electricity for cooling, resulting in relatively high energy consumption, this invention provides a combined cold storage and curing barn system. This system enables the refrigeration components to preheat the air intake of the curing barn while simultaneously cooling the cold storage, thereby reducing the overall energy consumption of both the cold storage and the curing barn.

[0033] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the combined system of cold storage 2 and drying room 1 in one embodiment of the present invention. The combined system of cold storage 2 and drying room 1 includes a main component and a refrigeration component. The main component includes a drying room 1 and a cold storage 2. The drying room 1 is provided with a heating chamber 11 and a drying chamber 12. The heating chamber 11 has an air inlet 11a and an air outlet 11b, and the air outlet 11b is connected to the drying chamber 12. The refrigeration component is used for refrigeration and has an evaporator 3 and a condenser 4 connected to each other. The evaporator 3 is located in the cold storage 2, and the condenser 4 is located at the air inlet 11a and can exchange heat with the air entering the heating chamber 11 from the air inlet 11a.

[0034] In the combined system of cold storage 2 and drying room 1 provided by this utility model, the evaporator 3 of the refrigeration component is placed in the cold storage 2. The liquid refrigerant in the evaporator 3 absorbs heat during the process of converting into a gaseous state, so as to achieve the cooling of the cold storage 2. When the gaseous refrigerant is delivered to the condenser 4, it is liquefied again and dissipates heat in the condenser 4. Since the condenser 4 is located at the air inlet 11a of the heating chamber 11, it can exchange heat with the air entering the heating chamber 11 from the air inlet 11a, so as to achieve the preheating of the air entering the heating chamber 11. The air entering the heating chamber 11 also dissipates heat to the evaporator 3, ensuring the normal operation of the refrigeration component. Thus, the refrigeration component can preheat the air entering the drying room 1 while cooling the cold storage 2, thereby reducing the overall energy consumption of the cold storage 2 and the drying room 1.

[0035] It should be noted that the evaporator 3 of the refrigeration assembly achieves a cooling effect by absorbing heat from the surrounding medium as the refrigerant changes from a liquid to a gaseous state; while the condenser 4 condenses high-temperature, high-pressure gas or vapor into a liquid, releasing heat in the process; and the condenser 4 is typically composed of condenser coils, with gaps between adjacent coil sections for ventilation. The evaporator 3 and condenser 4 are important components of the refrigeration assembly, connected by refrigerant pipes. Their specific structure and operating principles are existing technology and will not be elaborated upon here.

[0036] In one embodiment, please refer to Figures 2 to 4 The drying chamber 1 also has a dehumidification channel 1a and an air inlet channel 1b. The dehumidification channel 1a connects the drying chamber 12 to the outside, and the air inlet channel 1b connects the air inlet 11a to the outside. The main component also includes a heat-conducting structure 5, which is located between the dehumidification channel 1a and the air inlet channel 1b, so that the air in the dehumidification channel 1a can exchange heat with the air in the air inlet channel 1b.

[0037] In this embodiment, the dehumidification channel 1a of the drying chamber 12 and the air inlet channel 1b of the heating chamber 11 are connected by a heat-conducting structure 5, so that the hot and humid air in the dehumidification channel 1a can exchange heat with the dry and cold air in the air inlet channel 1b, thereby increasing the air inlet temperature of the heating chamber 11 and further reducing the overall energy consumption.

[0038] In one embodiment, the dehumidification channel 1a has a dehumidification section 1a1 and a connecting section 1a2. The dehumidification section 1a1, the air inlet channel 1b, the heating chamber 11 and the drying chamber 12 are arranged in sequence. One end of the dehumidification section 1a1 is connected to the outside, and the other end is connected to the drying chamber 12 via the connecting section 1a2.

[0039] In this embodiment, the dehumidification section 1a1 and the air inlet channel 1b are arranged adjacent to each other to shorten the distance between them, accelerate the heat transfer between them, and improve the heat transfer efficiency. At the same time, the heat in the heating chamber 11 can also be transferred to the air inlet channel 1b to further preheat the air in the air inlet channel 1b. Furthermore, the sequential arrangement of the above-mentioned air channels also improves the compactness of the drying chamber 1.

[0040] In one embodiment, the dehumidification section 1a1 extends in the same direction as the air inlet channel 1b; the heat-conducting structure 5 is disposed between the dehumidification section 1a1 and the air inlet channel 1b.

[0041] In this embodiment, the extension directions of the dehumidification section 1a1 and the air inlet channel 1b are set to be the same to increase the thermal contact area between them, and the heat-conducting structure 5 is arranged along the arrangement direction of both to further improve the heat transfer efficiency between them. Specifically, in this scheme, both the dehumidification section 1a1 and the air inlet channel 1b are arranged in a horizontal direction.

[0042] In addition, the heating chamber 11 is also arranged to extend horizontally, so that the airflow can circulate horizontally. In one embodiment, a long strip heating chamber 11 with a width of 50 cm and a length of 3.6 m can be arranged on one side of the baking chamber 1. The huge heating chamber 11 can be filled with a large amount of fuel at one time, maintaining several times the unattended time of the transmission baking chamber 1.

[0043] In one embodiment, the end of the dehumidification section 1a1 that connects to the outside and the end of the air inlet duct 1b that connects to the outside are located on the same side of the drying chamber 1, and the connecting section 1a2 and the air inlet 11a are located on the same side of the drying chamber 1, and the end of the dehumidification section 1a1 that connects to the outside is located on opposite sides of the drying chamber 1.

[0044] In this embodiment, the outer end of the dehumidification section 1a1 that is connected to the air inlet channel 1b is located on the same side of the drying chamber 1, and the air inlet 11a and the connecting section 1a2 are located on the other side of the drying chamber 1, thereby extending the travel of the incoming air in the air inlet channel 1b, so that the air between the air inlet channel 1b and the dehumidification section 1a1 can be fully heated.

[0045] It should be noted that the heat-conducting structure 5 can be in the form of a heat-conducting copper pipe, a heat-conducting plate, or other forms.

[0046] In one embodiment, the heat-conducting structure 5 includes a plurality of heat-conducting fins, which are disposed between the dehumidification section 1a1 and the air inlet channel 1b, and are arranged sequentially along the extension direction of the dehumidification section 1a1.

[0047] In this embodiment, multiple heat-conducting fins of the heat-conducting structure 5 are arranged sequentially along the extension direction of the dehumidification section 1a1, so that the dehumidification section 1a1 and various parts in the extension direction of the air inlet channel 1b can exchange heat evenly, thereby improving the heat exchange efficiency.

[0048] In one embodiment, the dehumidification channel 1a has a return port 1a3 that connects to the heating chamber 11, and the return port 1a3 and the air inlet 11a are located on the same side of the heating chamber 11; the main component also includes a one-way valve 6, which is located at the return port 1a3 and can restrict the flow of air from the heating chamber 11 to the dehumidification channel 1a.

[0049] In this embodiment, the dehumidification channel 1a is also connected to the heating chamber 11 via a one-way valve 6. When the humidity of the air discharged from the dehumidification channel 1a is low, the air in the dehumidification channel 1a can be transported to the heating chamber 11 via the one-way valve 6. Since the temperature of the air discharged from the dehumidification channel 1a is relatively high, energy consumption can be further reduced. It should be noted that the one-way valve 6 can transport air from the dehumidification channel 1a to the heating chamber 11 and restrict the air in the heating chamber 11 from entering the dehumidification channel 1a.

[0050] In one embodiment, the combined system of cold storage 2 and drying room 1 also includes a preheating structure located on the top of drying room 1, which can absorb the heat of sunlight and has a preheating channel that connects the air inlet 11a to the outside.

[0051] In this embodiment, a preheating structure is also provided on the top of the cold storage 2 and the drying room 1. This preheating structure absorbs solar heat, and when dry, cold air enters the preheating channel of the preheating structure, it can exchange heat with the preheating structure. Specifically, in the embodiment based on the aforementioned air inlet channel 1b and dehumidification channel 1a, the preheating channel connects to the end of the air inlet channel 1b furthest from the air inlet 11a, and is connected to the air inlet 11a via the air inlet channel 1b. Furthermore, the preheating structure is only located on the top of the drying room 1.

[0052] It should be noted that the preheating structure can be a pipe made of a material with strong solar heat absorption capacity, or it can be a part of the top of the baking room 1 made of a material with strong solar heat absorption capacity to form a preheating channel, or it can be other forms.

[0053] Specifically, in one embodiment, the preheating structure is formed of organic or tempered glass, with a preheating channel enclosed by the glass, and black corundum coated on the glass surface. Furthermore, a dehumidification structure can be provided at the front end of the preheating structure to remove moisture from the dry, cold air before it is conveyed to the preheating channel for heat exchange. It should be understood that the dehumidification structure can be a desiccant, a dehumidification plate with weak heat absorption capacity and a smooth surface, a dehumidification film, or other structures.

[0054] In one embodiment, the heating chamber 11 has a blower chamber 11c and a furnace chamber 11d, and the air inlet 11a, the blower chamber 11c, the furnace chamber 11d and the drying chamber 12 are connected in sequence; the main components also include a photovoltaic panel and a blower 7, the photovoltaic panel is located on the top of the cold storage 2 and / or the drying room 1, and the blower 7 is located in the blower chamber 11c and is electrically connected to the photovoltaic panel.

[0055] In this embodiment, solar energy can be converted into electrical energy through photovoltaic panels and used by the blower 7, further reducing energy consumption and increasing the air intake of the drying chamber 1. It should be noted that the connection and cooperation between the photovoltaic panels and the blower 7 is existing technology and will not be described in detail here.

[0056] In one embodiment, please refer to Figure 5 The cold storage 2 is equipped with a refrigeration room 21 and a freezer room 22, with the freezer room 22 located inside the refrigeration room 21.

[0057] In this embodiment, the cold storage 2 is configured as a refrigerator compartment 21 and a freezer compartment 22, and the freezer compartment 22 is placed inside the refrigerator compartment 21, which allows the freezer compartment 22 to save more energy when maintaining a very low temperature. Specifically, in this solution, the freezer compartment 22 is located inside the refrigerator compartment 21 and shares a side wall with the refrigerator compartment 21, and an openable and closable door 23 is installed on the shared side wall.

[0058] It should be noted that, in one embodiment, the refrigeration assembly has two evaporators 3, each connected to a condenser 4, and located in the refrigerator compartment 21 and the freezer compartment 22 respectively. In another embodiment, two refrigeration assemblies are provided, one of which has a condenser 4 located at the air inlet 11a and an evaporator 3 located in the refrigerator compartment 21; and the other has a condenser 4 located outdoors and an evaporator 3 located in the freezer compartment 22.

[0059] In addition, in this embodiment, an control room 8 is provided between the cold storage 2 and the drying room 1.

[0060] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0061] In this design, the tobacco leaves are dried in the drying chamber 12, and the condenser 4 is placed at the air inlet 11a of the curing barn 1. This allows the refrigeration unit to simultaneously cool the cold storage 2 and heat the curing barn 1, reducing the overall energy consumption of both the cold storage 2 and the curing barn 1 to nearly 50%. Furthermore, the intermittent operation of the cold storage 2 unit successfully simulates the intermittent nature of natural sunlight, enabling the curing barn 1 to have a special function of "naturally conditioning and drying tobacco" when fuel heating is not used.

[0062] In addition, an L-shaped "photovoltaic panel" roof can be designed above the cold storage 2 and the drying room 1. When there is sufficient sunlight, the current from the photovoltaic panels drives the blower 7 to directly blow hot air from the top of the building into the drying room 1, enabling the drying room 1 to achieve a natural drying function with zero energy consumption.

[0063] Furthermore, the freezer compartment 22 is designed within the refrigerator compartment 21, which allows the freezer compartment 22 to save energy when maintaining a very low temperature. During the design process, placing the cold storage 2 in the north and the drying room 1 in the south maximizes airflow and solar energy absorption efficiency, representing the optimal orientation.

[0064] Furthermore, the airflow is set to horizontal circulation. Compared to traditional vertical circulation drying chambers, this design allows for the installation of a long, rectangular furnace, 50 cm wide and 3.6 m long, on one side of drying chamber 1. This large furnace can be filled with a large amount of fuel at once, maintaining several times the unattended time of a traditional drying chamber 1. Simultaneously, a heat exchange chamber is designed on one side of the furnace-type heating chamber 11 to facilitate sufficient heat exchange between the intake and exhaust air of drying chamber 1. This heat exchange chamber consists of an air intake channel 1b and a dehumidification section 1a1, and is 50 cm wide and 3.6 m long.

[0065] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
