Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of baking equipment, in particular to an airflow interactive intelligent baking room. Background Art
[0002] The airflow interactive drying room is an important equipment in the drying process. It improves the drying efficiency and uniformity of the material by controlling the flow of airflow. According to the direction of airflow, the common airflow interactive drying rooms are mainly divided into two types: airflow ascending type and airflow descending type.
[0003] Rising air drying room: This type of drying room is designed so that the hot air flows from bottom to top, transferring heat to the material when passing through the material layer, thereby achieving a drying effect. Since the density of hot air is less than that of cold air, it will naturally rise, so this design takes advantage of the natural flow characteristics of hot air. However, this also means that in the drying room, the air temperature will gradually decrease from the bottom to the top, resulting in an uneven temperature field for drying the material. The material at the bottom may be over-dried due to the high temperature, while the material at the top may be under-dried due to the low temperature.
[0004] Downward airflow drying room: In contrast to the upward airflow drying room, the downward airflow drying room is designed to allow hot air to flow from top to bottom. The advantage of this design is that it can use gravity to make the hot air cover the entire material layer more evenly, which theoretically helps to improve the uniformity of material drying. However, in actual operation, due to the natural upward trend of hot air, even in the downward airflow drying room, there will be a certain degree of temperature gradient, that is, the temperature gradually increases from top to bottom, which also affects the uniformity of material drying.
[0005] Whether it is an airflow-up or airflow-down drying room, since the airflow circulates in one direction, there is an obvious temperature gradient inside the drying room, which in turn affects the uniformity and efficiency of material drying. Utility Model Content

DETAILED DESCRIPTION
[0031] In order to more clearly explain the purpose, technical solution and advantages of the utility model, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model described below, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] As attached Figure 1-6As shown, an airflow interactive intelligent drying room includes a drying chamber 20, a heating chamber 30 located at one end of the drying chamber 20, a dehumidification window 10, a two-way fan 50, a heating device 60 (which is a prior art, such as a steam heat exchanger, which will not be described in detail), and an air inlet window 70 installed on the heating chamber 30; the upper and lower sides of the heating chamber 30 are connected to the drying chamber 20 through a guide housing 40 respectively; the guide housing 40 includes a bottom plate 41 in a right-angled triangle shape, and a bottom plate 41 is located above the bottom plate 41 and opposite to the bottom plate 41. The top plate 42 corresponds to the top plate 42, and the side plate 43 connecting the hypotenuse of the bottom plate 41 and the hypotenuse of the top plate 42; the dehumidification window 10 is installed on the side plate 43; the two right-angled sides of the bottom plate 41 and the top plate 42 are respectively connected to the drying chamber 20 and the heating chamber 30; the dehumidification window 10 is installed on the side plate 43 of the guide shell 40; a partition 80 is provided at the upper part of the heating chamber 30, and the two-way fan 50 is fixedly connected to the partition 80; the heating device 60 is fixedly connected in the heating chamber 30 and is located below the two-way fan 50.
[0033] The utility model guides the airflow in the drying room 20 through the guide shell 40, and the guide shell 40 is symmetrically arranged to form a trumpet shape, which can make the airflow circulation in the drying room more uniform. At the same time, the airflow in the drying room can be directly discharged toward the window hole of the dehumidification window 10 when returning, and the dehumidification efficiency is further enhanced.
[0034] As a technical solution for further improvement of the present embodiment, it also includes an intelligent controller 90, an upper temperature and humidity sensor 100 arranged at the upper part of the drying chamber 20, a lower temperature and humidity sensor 110 arranged at the lower part of the drying chamber 20, and a camera 120 arranged in the drying chamber 20; the camera 120, the upper temperature and humidity sensor 100, the lower temperature and humidity sensor 110, the driving element of the air inlet window 70 and the driving element of the dehumidification window 10 are all electrically connected to the intelligent controller 90.
[0035] Since the temperature field of the utility model is uniform, the tobacco leaves in various parts of the curing room change uniformly, the number of cameras 120 can be appropriately reduced, and only 1 to 4 cameras 120 are needed, and the intelligent curing effect is good. The intelligent controller 90 can control the air intake, dehumidification and the power of the two-way fan 50 according to the color of the tobacco leaves, and automatically adjust the temperature and humidity of the curing room. If the temperature in the drying room 20 is lower than the set target temperature, the intelligent controller 90 increases the power of the two-way fan 50 and increases the heat supply of the heating device 60. If the temperature in the drying room 20 is higher than the set target temperature, the intelligent controller 90 reduces the power of the two-way fan 50 and reduces the heat supply of the heating device 60 to keep the temperature stable.
[0036] As a further improved technical solution of this embodiment, Figure 7As shown, the dehumidification window 10 includes a window frame 1, a window door 2, and a driving mechanism 3 for driving the window door 2 to open and close; one side of the window door 2 is hinged to the window frame 1, and the window door 2 rotates in the air guide housing 40 when it is opened. One side of the window door 2 is connected to the window frame 1 through a rotating shaft 8; the window door 2 is fixedly connected to the rotating shaft 8, and the rotating shaft 8 is rotatably connected to the window frame 1; the driving mechanism 3 is a servo motor, which is fixedly connected to the window frame 1, and the output shaft of the servo motor is coaxially fixedly connected to the rotating shaft 8. The window frame 1 includes an outer frame body 4, a retaining edge 5 fixedly connected to the inner side of the outer frame and used to limit the window door 2, and a connecting plate 6 fixedly connected to the outer side of the outer frame body 4; the connecting plate 6 is provided with a mounting hole 7.
[0037] In the dehumidification window 10 of the utility model, the window door 2 can automatically rotate and open to the inside of the guide housing 40 during the dehumidification process. When the window door 2 is fully opened in the guide housing 40, the window door 2 plays a role in blocking and guiding the circulating airflow in the guide housing 40. The airflow in the guide housing 40 passes through the blocking and guiding effect of the window door 2, and more airflow is guided to the outside of the guide housing 40, so as to achieve the purpose of increasing dehumidification under the condition of the same window hole area.
[0038] In this embodiment, the window door 2 is opened with a rotation angle of 0-100°, and more preferably 0-60°.
[0039] As Figure 7 An alternative to the drive mechanism 3 shown is Figure 8 As shown, the driving mechanism 3 is a linear driving element; both ends of the linear driving element are hinged to the window frame 1 and the window door 2 respectively, and the linear driving element can be a cylinder, a hydraulic cylinder or an electric push rod.
[0040] Obviously, the moisture removal window 10 can also be used as follows Fig. 9 The driving mechanism shown, the driving mechanism 3 is a linear driving element fixedly connected to the window frame 1, the output end of the linear driving element is hinged to a connecting rod 9, the other end of the connecting rod 9 is hinged to the window door 2, and the linear driving element can be a cylinder, a hydraulic cylinder or an electric push rod.
[0041] In the dehumidification process of the utility model, the window door 2 can automatically rotate and open inside the air guide housing 40. When the window door 2 is fully opened inside the air guide housing 40, the window door 2 blocks the backflow of air, so that part of the high-humidity exhaust gas flows out from the window hole, the dehumidification effect is good, and the tobacco leaves are not easy to have dust, bubbles and other colors.
[0042] When the window 2 is closed, the airflow from the heating chamber 30 is better diverted by the trumpet-shaped cavity formed by the guide shell 40, and the airflow enters the drying chamber 20 more evenly. The temperature of each part in the drying chamber 20 is more uniform, and the tobacco baking effect is good.
[0043] As a preferred technical solution of this embodiment, the air inlet windows 70 are two sets, which are respectively installed at the upper and lower parts of the heating chamber 30, so that the two-way fan 50 can effectively replenish air when rotating forward and reversely.
[0044] When the utility model performs descending airflow circulation, Figure 4 As shown, if the humidity in the drying chamber 20 is greater than the set target humidity, the airflow is in a descending state, and the intelligent controller 90 closes the air inlet window 70 and the two dehumidification windows 10 at the upper part of the heating chamber 30 (not participating in the work), and opens the air inlet window 70 and the two dehumidification windows 10 at the lower part of the heating chamber 30 at a certain opening. Under the suction force of the two-way fan 50, fresh air outside the curing room is sucked into the curing room, and is heated to the set temperature by the heating device 60. The heated air enters the drying chamber 20, the moisture in the tobacco leaves is dried out, the air humidity increases, part of the high-humidity air returns to the heating chamber to continue circulating, and part of it is discharged from the curing room through the lower dehumidification window 10, and the humidity in the drying chamber 20 is controlled.
[0045] When the utility model performs ascending airflow circulation, Figure 4 As shown, if the humidity in the drying chamber 20 is greater than the set target humidity, the air flow is in an upward state, and the intelligent controller 90 closes the air inlet window 70 and the two dehumidification windows 10 at the bottom of the heating chamber 30 (not participating in the work), and opens the air inlet window 70 and the two dehumidification windows 10 at the top of the heating chamber 30 at a certain opening. Under the suction of the two-way fan 50, fresh air outside the curing room is sucked into the curing room, and is heated to the set temperature by the heating device 60. The heated air enters the drying chamber 20, the moisture in the tobacco leaves is dried out, the air humidity increases, part of the high-humidity air returns to the heating chamber to continue circulating, and part of it is discharged from the curing room through the upper dehumidification window 10, and the humidity in the drying chamber 20 is controlled.
[0046] The intelligent controller 90 of the utility model can adopt an IDC-300 temperature and humidity controller with networking and monitoring functions. The electronic components and controllers such as temperature and humidity sensors involved in the utility model are all existing technologies, which can be fully realized by those skilled in the art and need not be elaborated. At the same time, the content of the protection of the utility model does not involve the improvement of software and methods.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. For those skilled in the art, any modification, equivalent replacement and improvement of the technical solutions or partial technical features recorded in the above specific embodiments within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
