Abstract
Description
Technical Field
[0001] The invention belongs to the field of tobacco processing, and in particular relates to an intensive cigar drying room. Background Art
[0002] High-quality cigar tobacco leaves are the basis for making high-quality cigars. The aroma quality of cigar tobacco leaves is crucial to the quality of cigar products. After being picked, fresh cigar tobacco leaves enter the process of braiding and airing, also known as the drying process. This process is a key process that affects the aroma quality of cigar tobacco leaves. The quality of drying will directly affect the aroma of cigar tobacco leaves.
[0003] At present, cigar tobacco leaf drying generally relies on relatively simple facilities, such as building drying racks in ordinary warehouses for drying. This type of drying facility has poor thermal insulation and moisture retention performance, and requires multiple manual interventions on temperature and humidity. However, manual intervention is unable to accurately control the adjustment accuracy. During the humidification or ventilation and dehumidification process, the temperature and humidity fluctuate greatly, which has a great impact on the quality of cigar tobacco leaf drying and cannot achieve a good drying effect. To address this problem, we propose an intensive cigar tobacco drying room to improve the quality of cigar tobacco drying. Summary of the Invention
[0004] To solve the above problems, the present invention proposes an intensive cigar drying room. The drying room automatically controls humidity and temperature under the control of the control component, and accurately controls the humidity and temperature in the drying room, so that the conditions in the drying room can better meet the requirements of the cigar tobacco leaf drying process.
[0005] The specific plan is: an intensive cigar drying room, including multiple rooms, each room is equipped with a dehumidification component, a heat exchange component and a light adjustment component, a drying rack is provided in the room, and the room is also equipped with a control component, and the dehumidification component, heat exchange component and light adjustment component are all connected to the control component.
[0006] Furthermore, the dehumidification component includes a fan and a dehumidification curtain. The fan is arranged on one side of the room body, and the dehumidification curtain is arranged on the side opposite to the fan.
[0007] The dehumidification component also includes a humidity sensor. The control component is connected to the humidity sensor. The control component adjusts the operation of the fan and the switch of the dehumidification curtain according to the induction of the humidity sensor to adjust the humidity in the drying room.
[0008] Furthermore, the light adjustment component includes a sunshade curtain and an adjustment part. The sunshade curtain is laid on the top of the room and is connected to the adjustment part. The sunshade curtain is a venetian blind composed of several blades. The adjustment part can rotate to rotate the blades to adjust the transmittance of the sunshade curtain.
[0009] The cigar tobacco leaf drying process needs to be carried out in a cool environment, so the required light intensity is very low. Sunshades are set up to block the sunlight and avoid excessive light.
[0010] Furthermore, the heat exchange assembly includes a heat exchanger installed on the side of the room body, which is used to heat the drying room and for temperature control and compensation to avoid excessive temperature changes during ventilation that may affect the quality of the cigar tobacco leaves;
[0011] Furthermore, a moisture-recovery component is provided in the room, and the moisture-recovery component is connected to the control component. The tobacco leaves will be moistened after drying, and the moisture-recovery process also requires precise control of the humidity. Therefore, the various components and structures of the drying room are extremely compatible with the moisture-recovery process. The moisture-recovery component is combined with other structures of the drying room to achieve multiple uses of one room, expand the functionality of the drying room, increase the practicality of the drying room, and achieve unexpected results.
[0012] Furthermore, the moisture recovery component includes a water supply pipe evenly distributed in the room, the water supply pipe is set close to the ground, and a plurality of evenly distributed nozzles are provided on the water supply pipe, and the nozzles are preferably atomizing nozzles.
[0013] When rehumidification is required, the control unit first detects the humidity in the drying room and controls the water supply pipe to supply water. The water supply pipe sprays water onto the ground and then uses evaporation to increase the humidity in the drying room. The increased humidity allows the cigar tobacco leaves to absorb water independently to achieve rehumidification.
[0014] Furthermore, a conveying mechanism is provided in the room, which includes a loading part and a transport part. The transport part is arranged in accordance with the distribution direction of the drying rack. The conveying mechanism is provided and the electric conveying is used to save manpower and improve the transportation efficiency of loading and unloading.
[0015] At the same time, compared with manual transportation, electric transportation is highly planned and orderly, and it is not easy to affect the facilities in the drying room during transportation.
[0016] Furthermore, the rooms are arranged in parallel, operation rooms are interspersed between the rooms, and the loading part is arranged in the operation room.
[0017] The loading department is located in the operation room outside the air-drying room. A conveying window for tobacco leaves to enter and exit is provided between the operation room and the air-drying room. Preferably, the conveying window is provided with a hanging curtain. The loading is done in the operation room, and the transportation department of the air-drying room has staff who hang the transported tobacco leaves into the air-drying racks. During the air-drying process, the air-drying room has weak communication with the outside world, which reduces the impact of the outside world on the air-drying room environment.
[0018] Furthermore, the floor inside the room includes a soil layer, a sand layer is laid on the soil layer, and a non-woven fabric layer is covered on the sand layer; the bottom surface of the operation room includes a hardened layer;
[0019] The drying rack and transportation mechanism are both set up along the direction from the operation room to the drying room. The transportation part is set higher than the drying rack. A smoke hanging duct made of a hardened layer is provided next to the drying rack. This layout is conducive to convenient smoke hanging.
[0020] Furthermore, a drainage channel and a dehumidification window are provided in the room. The drainage channel is provided on the floor of the room and is on the same plane as the sand layer. The dehumidification window is provided on the top of the room and is provided with an insect-proof net.
[0021] During airing, the non-woven fabric and the sand layer have high permeability, and the sand layer is not easy to retain water, which further increases the air permeability in the airing room and is conducive to rapid drying in the room. On the other hand, it is used to absorb moisture in the air and condense moisture. Compared with the sand layer, the soil layer has a smaller temperature change, and it also has a certain thermal insulation effect when combined with the non-woven fabric, which is used to reduce the temperature difference in the airing room.
[0022] During moisture regain, the non-woven fabric can absorb water quickly and retain only a small amount of water. The excess water is drained away by the sand layer, avoiding excessive humidity caused by adding too much water at one time and then causing excessive moisture regain, which is conducive to fine adjustment of humidity.
[0023] Furthermore, the room body includes a frame and an insulation film wall. The frames between adjacent rooms are detachably connected, and an insulation film wall is provided outside the frame. The drying room with this structure can be modularly assembled and disassembled, is simple to construct, and has high installation efficiency.
[0024] Furthermore, the frame comprises an aluminum alloy body and an anti-corrosion polyester coating sprayed on the surface, and the insulation mold comprises a plastic film layer and a felt layer;
[0025] The control component is provided with a storage module, which pre-stores a control program that conforms to the drying and rehumidification of cigar tobacco leaves. The program is set according to the optimal temperature and humidity in the corresponding time period in the cigar tobacco leaf drying process. This can be achieved using existing technology.
[0026] The beneficial effects of the present invention are:
[0027] (1) The air-drying room of the present invention can adaptively and precisely control the temperature and humidity during the air-drying and rehumidification processes of cigar tobacco leaves, so that the tobacco leaves can be at the optimal temperature and humidity in each stage of air-drying and rehumidification, so that the air-drying and rehumidification quality of the cigar tobacco leaves can reach the best.
[0028] (2) The floor of the drying room of the present invention is made of a combination of sand layer and non-woven fabric. On the one hand, the air permeability in the drying room can be further increased during drying, which is conducive to rapid drying in the room. On the other hand, when moisture is regained, water can be quickly absorbed and discharged, so that only a small amount of water is retained in the room, avoiding the accumulation of a large amount of water, which leads to excessive humidity after evaporation, thereby affecting the moisture regain effect.
[0029] (3) The modular and detachable room of the present invention is easy to install and has high assembly flexibility. An operation room is set between the air-drying rooms to separate transportation and air-drying, thereby reducing the impact of the outside world on the environment in the air-drying room and uncontrollable factors, which is more conducive to the stability of the environment during the air-drying process.
