Technical Field
[0001] This utility model relates to the field of drying technology in tobacco-rice rotation areas, and specifically to a device for drying rice in tobacco-rice rotation areas. Background Technology
[0002] A tobacco-rice rotation area refers to a specific region that adopts a tobacco-rice rotation planting pattern. Tobacco-rice rotation is a planting pattern in which tobacco is first planted in the same paddy field, and rice is planted after the tobacco harvest. After the rice harvest, the land is left to rest or green manure is planted. This pattern is mainly distributed in some water and heat resource-rich areas in southern my country, such as Sichuan, Fujian, Guangxi, Yunnan, and Guizhou.
[0003] In tobacco-rice rotation areas, a large number of dedicated tobacco curing barns are built for curing (processing) tobacco leaves. However, because tobacco production is seasonal, with only one season per year, the curing barns are left idle after the tobacco leaves are dried (processed) and will be used again the following year.
[0004] The region has a large amount of soil used for crop rotation to grow rice. The rice needs to be dried in a field or facility. Especially during rainy weather, the field and facility are even more scarce, which leads to the rice not being dried in time and thus rotting and being lost.
[0005] Therefore, there is an urgent need for a device that can utilize tobacco curing barns in idle tobacco-rice rotation areas and achieve timely drying of rice, in order to solve the problems existing in the current technology. Utility Model Content
[0006] The purpose of this invention is to provide a device for drying rice in a tobacco-rice rotation area in order to solve the problems existing in the prior art.
[0007] In order to solve the problems existing in the prior art, the present invention adopts the following technical solution:
[0008] An apparatus for drying rice in a tobacco-rice rotation area is provided. The area is equipped with a tobacco curing barn, which contains a burner and a blower. At least one breathable pad is detachably installed in the tobacco curing barn, and rice is laid on the breathable pad.
[0009] As an improvement to the technical solution of the device for drying rice in the tobacco-rice rotation area of this utility model, the breathable pad layer is a bamboo pad layer.
[0010] As an improvement to the technical solution of the device for drying rice in the tobacco-rice rotation area of this utility model, the bamboo pad layer includes at least one bamboo pad, each bamboo pad includes a bamboo pad body and a rotating part, and the rotating part is arranged on opposite sides of the bamboo pad body.
[0011] The bamboo mat body comprises multiple bamboo strips, which are arranged in a crisscross pattern.
[0012] As an improvement to the technical solution of the device for drying rice in the tobacco-rice rotation area of this utility model, each bamboo strip is 1.0-1.5cm wide and 1.0-1.5mm thick.
[0013] As an improvement to the technical solution of the device for drying rice in the tobacco-rice rotation area of this utility model, the feature is that each of the bamboo mats is a bamboo mat with a length of 5-10 meters and a width of 1.0-2.0 meters.
[0014] As an improvement to the technical solution of the device for drying rice in the tobacco-rice rotation area of this utility model, at least one layer of the aforementioned breathable pad is provided on the support.

[0027] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0028] like Figures 1 to 7 As shown, an apparatus for drying rice in a tobacco-rice rotation area is disclosed, which is used in such an area. The area includes a tobacco curing barn 1, which contains a burner 2 and a blower 3.
[0029] In this invention, by using at least one breathable padding layer 4 for laying rice in the tobacco curing barn 1, and by utilizing the burner 2 in the tobacco curing barn 1 to increase the air temperature in the tobacco curing barn 1, the hot air in the tobacco curing barn 1 is used to dry the rice. This simultaneously solves the problems of the existing technology regarding the idleness of the tobacco curing barn 1 in tobacco-rice rotation areas, and the problem of the rice not being dried in a timely manner in tobacco-rice rotation areas.
[0030] In detail, the tobacco-rice rotation area refers to a specific region that adopts the tobacco-rice rotation planting pattern. Tobacco-rice rotation is a planting pattern in which tobacco is first planted in the same paddy field, and after the tobacco is harvested, rice is planted. After the rice is harvested, the land is left to rest or green manure is planted.
[0031] In tobacco-rice rotation areas, a tobacco curing barn (1) is typically set up. During the tobacco production season, the tobacco leaves can be dried using the barn. However, during the non-tobacco production season, the tobacco curing barn (1) remains idle. Additionally, rice is also grown in these areas. After harvesting, the rice grains require space and / or facilities for drying. During rainy or humid weather, the lack of such space and facilities leads to the rice grains not drying in time and rotting, resulting in losses.
[0032] Based on this, the present invention provides a device for drying rice in a tobacco-rice rotation area, which is used in a tobacco-rice rotation area. The tobacco curing barn 1 set in the tobacco-rice rotation area is equipped with a burner 2 and a blower 3. At the same time, at least one layer of breathable padding 4 for laying rice is detachably set in the tobacco curing barn 1.
[0033] During the tobacco production season, the tobacco curing barn 1 is used to dry the tobacco leaves. At this time, the breathable padding layer 4 for laying rice is not installed in the tobacco curing barn 1.
[0034] In non-tobacco production, the blower 3 in the tobacco curing barn 1 is first used to remove the tobacco odor, making the environment inside the barn relatively clean. Then, at least one layer of breathable mat is set up inside the tobacco curing barn 1, and rice is laid on the mat. The rice is then placed on the mat, and the burner 2 and blower 3 are used to raise the temperature inside the barn and circulate the hot air, creating an environment for drying the rice. This process dries the rice placed on the breathable mat, solving the problems of the tobacco curing barn 1 being idle in tobacco-rice rotation areas and the inability to dry the rice in a timely manner in tobacco-rice rotation areas.
[0035] The burner 2 provides a stable heat source for the tobacco curing barn 1, ensuring the efficient operation of the drying process. Meanwhile, under the action of the blower 3, the heat energy is evenly transferred to the rice paddies laid on the breathable mat. With the combined action of the burner 2 and the blower 3, the tobacco curing barn 1 can produce high-quality, uniformly dried rice.
[0036] In some embodiments of this utility model, the breathable pad layer 4 is a bamboo pad layer.
[0037] First, the bamboo mat layer effectively absorbs some of the moisture in the rice. Second, using a bamboo mat layer in the curing barn reduces the risk of bacterial contamination of the rice during drying, thus improving the drying quality and safety. Bamboo is a rapidly growing and highly renewable plant resource. Using a bamboo mat layer not only reduces reliance on traditional wood but also lowers environmental pressure. Furthermore, bamboo processing generates relatively little pollution, aligning with environmental protection and sustainable development principles. The bamboo mat layer also improves the environment within the curing barn, offering good air permeability and insulation, helping to maintain temperature uniformity and stability, thereby improving curing efficiency and quality. Moreover, its low cost, ease of acquisition and processing, and durability reduce material costs. The bamboo mat layer's longevity also reduces replacement frequency, further lowering maintenance costs. Additionally, the bamboo mat layer's high hardness allows for multi-layer stacking on supports, maximizing the use of limited curing barn space for drying rice.
[0038] The tobacco curing barn 1 also includes a viewing window 8 and a doorway 9 to facilitate ventilation and personnel access when the tobacco curing barn 1 is not in operation.
[0039] As a specific embodiment of this method, the bamboo mat layer includes at least one bamboo mat 5. Each bamboo mat 5 includes a main body and a rotating part 7, with the rotating part 7 disposed on opposite sides of the main body. The main body of the bamboo mat 5 includes multiple bamboo strips 6 arranged in a crisscross pattern. Based on the characteristics of the bamboo mat 5, the main body of the mat is composed of multiple bamboo strips 6 arranged in a crisscross pattern, which ensures its air permeability and better guarantees the drying effect of rice under drying conditions.
[0040] In addition, in this embodiment, since the rotating part 7 is provided on both sides opposite to the main body of the bamboo mat 5, the bamboo mat 5 can be rotated and folded up by the rotating part 7. During the tobacco production season, the bamboo mat layer can be folded up so that the tobacco leaves can be dried.
[0041] The rotating part 7 can be a strip-shaped object made of wood, bamboo, or materials such as PVC or wood. The bamboo mat 5 is rolled up and retracted using the rotating part 7 as an axis.
[0042] As the first specific embodiment of this implementation, each bamboo strip 6 is 1.0-1.5cm wide and 1.0-1.5mm thick. Since the main body of the bamboo mat 5 includes multiple bamboo strips 6, the bamboo strips 6 of this size can be easily rolled up for easy storage.
[0043] As a second specific embodiment of this method, each bamboo mat 5 is 5-10 meters long and 1.0-2.0 meters wide. This size of bamboo mat 5 makes it easy to store. During the tobacco production season, the bamboo mat 5 can be easily stored away to dry the tobacco leaves. During the non-tobacco production season, the bamboo mat 5 can be laid in the tobacco curing barn 1 to form at least one layer of bamboo mats, and then rice can be laid on the bamboo mat layer to dry the rice.
[0044] In some embodiments of this invention, at least one breathable pad layer 4 is disposed on the support. Preferably, the support can be a tobacco rack or a foldable support.
[0045] In detail, in this utility model, the breathable pad layer 4 can be set on the support, and the multiple breathable pad layers 4 can be set in layers to increase the storage space for rice in the same tobacco curing barn 1.
[0046] When the support frame is foldable, it can be easily folded up during the non-tobacco production season, providing enough space for the tobacco leaves to dry.
[0047] More specifically, as the first specific embodiment of this invention, the present invention includes a breathable pad layer 4, which is laid on the floor of the tobacco curing barn.
[0048] As a second specific embodiment of this invention, the present invention includes at least two layers of breathable pads 4. The at least two layers of breathable pads 4 are arranged in a layered manner with a support structure, which can increase the amount of rice stored in the tobacco curing room and ensure the distance between the layered breathable pads 4, thereby ensuring the drying effect of the rice.
[0049] The support includes a first support 10 installed on the inner wall of the tobacco curing barn and a second support 11 installed in the middle of the tobacco curing barn; at least one breathable pad layer 4 is installed on the first support 10 and the second support 11, so that the structure in the tobacco curing barn can be better utilized.
[0050] Alternatively, the support frame can be foldable or detachable, allowing for increased drying capacity by adding multiple layers of breathable padding when rice needs to be dried.
[0051] Furthermore, at least one support rod 12 is connected between the first support 10 and the second support 11, which can support the breathable padding layer 4.
[0052] In some embodiments of this utility model, the burner 2 is located at the lower part of the side wall of the tobacco curing barn 1 and / or at the bottom of the tobacco curing barn 1, and the blower 3 is located at the lower part of the tobacco curing barn 1. The burner 2 and the blower 3 work together to ensure the uniform distribution of heat in the tobacco curing barn 1. In conjunction with the exhaust system, the full contact between the rice and the hot air and the air circulation effect of the tobacco curing barn 1 can be ensured at the same time.
[0053] As the first specific embodiment of this utility model, on a sunny day in a tobacco-rice rotation area, after the tobacco curing barn 1 has finished curing, it is cleaned and tidied, and the blower 3 is turned on to blow away any remaining tobacco smell. Bamboo is split into bamboo strips 6 that are 1.0-1.5 cm wide and 1.0-1.5 mm thick. Then, the bamboo strips 6 are woven together in a crisscross pattern to form a bamboo mat 5 that is 8.0 meters long and 1.3 meters wide. The two ends are connected to round wood or bamboo, making it easy to rotate and unfold along the round wood or bamboo. When needed, the bamboo mat 5 is unfolded and laid on the ground of the tobacco curing barn 1. Rice is placed on the bamboo mat 5 and spread to a thickness of 0.5-1.0 cm. Then, the burner 2 and blower 3 of the tobacco curing barn 1 are turned on to raise the temperature to about 45-50℃ until the rice is completely dried. Then, the rice is stored and the bamboo mat 5 is stored by rotating along the round wood or bamboo. Using this utility model to dry rice saves 30 hours compared to drying rice in the sun on a sunny day.
[0054] As a second specific embodiment of this utility model, on a cloudy day in a tobacco-rice rotation area, after the tobacco curing barn 1 has finished curing, it is cleaned and tidied, and the blower 3 is turned on to blow away any remaining tobacco smell. Bamboo is split into bamboo strips 6 that are 1.0-1.5 cm wide and 1.0-1.5 mm thick. Then, the bamboo strips 6 are woven together in a crisscross pattern to form a bamboo mat 5 that is 8.0 meters long and 1.3 meters wide. The two ends are connected to round wood or round bamboo, making it easy to rotate and unfold along the round wood or round bamboo. When needed, the bamboo mat 5 is unfolded and laid on the ground of the tobacco curing barn 1. Rice is placed on the bamboo mat 5 and spread to a thickness of 0.5-1.0 cm. Then, the burner 2 and blower 3 of the tobacco curing barn 1 are turned on to raise the temperature to about 45-50 degrees Celsius until the rice is completely dried. Then, the rice is stored and the bamboo mat 5 is stored by rotating along the round wood or round bamboo. Using this utility model to dry rice saves 70 hours compared to drying rice on a cloudy day.
[0055] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
