Description

Technical Field

[0001] This utility model relates to the field of preservation technology, and in particular to a beet ventilation preservation device. Background Technology

[0002] The purpose of beet preservation is to maintain the freshness and excellent quality of beet tubers for a longer period of time, minimize sugar loss before processing, and create conditions for the workshop to process high-quality beets and produce more sugar.

[0003] The sugar production cycle in Xinjiang is generally 90-120 days. However, the sugar beet harvest is concentrated in a short period, requiring the majority of the beets to be stored for daily processing in the factories. The quality of sugar beet preservation directly affects the processing time and sugar yield in sugar mills. Therefore, improving sugar beet preservation technology is of great significance to the sugar industry.

[0004] Due to the biological characteristics of sugar beets, they remain alive and continue to develop during storage, which consumes most of their sugar content. Weather changes and temperature fluctuations within the beet pile significantly impact the quality of stored sugar beets. Furthermore, with the increasing mechanization of sugar beet production, the area under machine harvesting is expanding, and the amount of machine-harvested sugar beets is rapidly increasing. Because machine-harvested sugar beets have a higher breakage rate, they are prone to mold growth during storage, which not only increases sugar loss but also causes the organic acids produced by mold to affect subsequent processing. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a beet ventilation and preservation device that can reduce the temperature inside the beet pile, thereby reducing beet respiration and controlling the reproduction of related microorganisms, thus minimizing sugar loss during storage.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A beet ventilation and preservation device includes a main air duct, branch air ducts and a blower. The main air duct includes a plurality of first splicing pipes, and adjacent first splicing pipes are connected through a first splicing member. The first splicing pipe at one end of the main air duct is connected to the air outlet of the blower.

[0008] The branch duct includes multiple second splicing pipes, each of which has multiple air guide holes evenly spaced. Adjacent second splicing pipes are connected by a second splicing member. The second splicing member at one end of the branch duct is connected to the first splicing member. An electric damper is provided between the first splicing member and the second splicing member. The end of the second splicing member at the other end of the branch duct that is furthest from the corresponding second splicing pipe is a closed structure.

[0009] An installation frame is erected between two adjacent branch ducts. An installation pipe is vertically installed in the middle of the installation frame. A temperature sensor is installed inside the installation pipe, and the probe of the temperature sensor extends through the outside of the installation pipe. The temperature sensor is electrically connected to the blower and the electric damper through a controller.

[0010] Furthermore, the second splicing component has connecting parts at both ends, and each connecting part has a through mounting hole, which is provided with a connecting bolt.

[0011] The second splicing pipe has through threaded holes at both ends. The connecting part is sleeved on the outside of the second splicing pipe, and the connecting bolt slides through the connecting part and is threaded into the second splicing pipe through the threaded holes.

[0012] Furthermore, a limiting ring is provided at the end of the connecting part away from its opening, and when the second splicing pipe abuts against the limiting ring, the threaded hole is aligned with the mounting hole.

[0013] Furthermore, the first splicing component is a three-way structure, with its two opposite ends threaded onto the outside of the first splicing pipe, and the other end being a docking end. The docking end is embedded in one end corresponding to the second splicing component, and the corresponding connecting bolt can slide through the connecting part and then be threaded into the docking end; the electric damper is located at the docking end.

[0014] Furthermore, the mounting bracket is provided with fasteners at both ends. One end of the fastener is an open structure so that the fastener can be locked onto the outside of the second splicing pipe. The fastener is provided with a limiting screw, which is threaded through the fastener and abuts against the second splicing pipe.

[0015] Furthermore, the blower's air inlet is provided with a three-way pipe, the first end of the three-way pipe is connected to the air inlet of the blower, the second end of the three-way pipe is provided with a first switching valve, the third end of the three-way pipe is provided with a drying chamber, and the third end of the three-way pipe is connected to the drying chamber through a second switching valve.

[0016] A humidity sensor is installed inside the mounting tube, and the probe of the humidity sensor extends outside the mounting tube. The humidity sensor, the first switching valve, and the second switching valve are electrically connected to the controller.

[0017] Furthermore, the drying oven includes a box body and a moisture-absorbing box. The box body has through openings at both ends. One opening is connected to the third end of the three-way pipe, and the other opening is an air inlet. Sliding grooves are provided on opposite sides of the inner wall of the box body. The moisture-absorbing box is slidably embedded into the box body through the sliding grooves on both sides. The moisture-absorbing box contains a desiccant. A lid is provided on the top of the box body, and the lid is connected to the box body on both sides by fasteners.

[0018] Furthermore, it also includes a storage tank for storing disinfectant. The storage tank is equipped with a booster pump, and the pump has a drain pipe at its discharge end. One end of the drain pipe is connected to the booster pump, and the other end extends out of the storage tank and is equipped with an atomizing head. The atomizing head is embedded in the main air duct near the blower.

[0019] Furthermore, a support frame is provided at the bottom of the second splicing component.

[0020] The beneficial effects of this utility model are:

[0021] 1. Since adjacent first splicing pipes are connected by first splicing parts and adjacent second splicing pipes are connected by second splicing parts, the appropriate number of first and second splicing pipes can be selected according to the width and length of the beet pile. This utility model allows for the installation of main and branch air ducts through free combination, which facilitates on-site installation and splicing, and also facilitates material transportation. When the average temperature is ≤15℃, beet stacking for storage begins, and the height of the beet pile does not exceed 3.5 meters. Temperature data of the beet pile is obtained through temperature sensors. When the temperature of the beet pile obtained by the temperature sensor is ≥8℃, the controller controls the blower to open and the corresponding electric damper to open, allowing the cooler outside air to enter the beet pile. Through forced ventilation, the temperature inside the beet pile can be quickly reduced in a short time, keeping the temperature difference between the inside and outside of the beet pile at about 5℃, with an average reducing sugar content of ≤0.1%, which can effectively control the spoilage and rot of beets caused by temperature rise.

[0022] 2. The humidity inside the beet pile is measured by a humidity sensor. When the humidity exceeds the threshold, the controller controls the blower to turn on and the corresponding electric damper to open. At the same time, it controls the first switch valve to close and the second switch valve to open, so that the outside air passes through the desiccant in the desiccant box to dehumidify, thereby introducing dry air into the beet pile and reducing the humidity inside the beet pile. This prevents free water on the surface of the beet roots from causing parasitic bacteria to flow, invade healthy tissue, and cause rot. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please also see Figures 1 to 6 The beet ventilation and preservation device of the present invention, according to a preferred embodiment, includes a main air duct 1, a branch air duct 2 and a blower 3.

[0034] The main air duct 1 includes multiple first splicing pipes 11, and adjacent first splicing pipes 11 are connected by first splicing parts 4; the first splicing pipe 11 at one end of the main air duct 1 is connected to the air outlet of the blower 3.

[0035] The branch duct 2 includes multiple second splicing pipes 21. Multiple air guide holes 212 are evenly spaced on the second splicing pipes 21. Adjacent second splicing pipes 21 are connected by second splicing parts 5. The second splicing part 5 at one end of the branch duct 2 is connected to the first splicing part 4. An electric damper 31 is provided between the first splicing part 4 and the second splicing part 5. The end of the second splicing part 5 at the other end of the branch duct 2 away from the corresponding second splicing pipe 21 is a closed structure.

[0036] In this embodiment, air vents 212 are provided around the second splicing pipe 21, and a mesh is provided on the air vents 212 to prevent soil from the beets from falling into the second splicing pipe 21. Figure 3 As shown, a support frame 53 is provided at the bottom of the second splice 5, so that the branch pipe 2 can be supported on the ground, and the air guide hole 212 of the second splice pipe 21 facing the ground is blocked.

[0037] An installation frame 6 is installed between two adjacent branch ducts 2. An installation pipe 61 is vertically installed in the middle of the installation frame 6. A temperature sensor 62 is installed inside the installation pipe 61, and the probe of the temperature sensor 62 extends outside the installation pipe 61. The temperature sensor 62 is electrically connected to the blower 3 and the electric damper 31 through a controller. Both ends are sealed.

[0038] like Figure 4 As shown, the mounting bracket 6 has fasteners 601 at both ends. One end of the fastener 601 is open, allowing it to be secured to the outside of the second splicing pipe 21. The fastener 601 also has a limiting screw 602 threaded through it and abutting against the second splicing pipe 21. The fasteners 601 and limiting screws 602 secure the mounting bracket 6 between two adjacent branch pipes 2. In this embodiment, the mounting bracket 6 is installed as close as possible to the middle of the branch pipe 2, allowing the temperature sensor 62 to obtain temperature information from the middle of the beet pile.

[0039] In this embodiment, since adjacent first splicing pipes 11 are connected by first splicing member 4 and adjacent second splicing pipes 21 are connected by second splicing member 5, the appropriate number of first splicing pipes 11 and second splicing pipes 21 can be selected according to the width and length of the beet pile. This utility model can install the main air duct 1 and branch air duct 2 in a free combination manner, which can facilitate on-site installation and splicing, and also facilitate the transportation of materials.

[0040] When the average temperature is ≤15℃, beet stacking for preservation begins, and the height of the beet stack does not exceed 3.5 meters. Temperature data of the beet stack is obtained through temperature sensor 62. When the temperature of the beet stack obtained by temperature sensor 62 is ≥8℃, the controller controls the blower 3 to open and the corresponding electric damper 31 to open, allowing the cooler outside air to enter the beet stack. Through forced ventilation, the temperature inside the beet stack can be reduced quickly in a short time, so that the temperature difference between the inside and outside of the beet stack is maintained at about 5℃, and the average reducing sugar is ≤0.1%. This can effectively control the spoilage and rot of beets caused by temperature rise.

[0041] like Figure 1 and Figure 2 As shown, the second splicing component 5 has connecting parts 51 at both ends, and the connecting parts 51 have through mounting holes 511, with connecting bolts 52 installed in the mounting holes 511.

[0042] The second splicing pipe 21 has through threaded holes 211 at both ends. The connecting part 51 is sleeved on the second splicing pipe 21, and the connecting bolt 52 slides through the threaded holes 211 after passing through the connecting part 51 and is threaded into the second splicing pipe 21. In this embodiment, the opening of the second splice 5 at the end of the branch pipe 2 away from the main pipe 1 is covered with a sealing cap, and the end of the main pipe 1 away from the blower 3 is also covered with a sealing cap. The sealing cap can be made of rubber and is elastically sleeved on the corresponding second splice 5 or the first splicing pipe 11. The second splice 5 in this embodiment is also provided with air guide holes 212.

[0043] A limiting ring 512 is provided at the end of the connecting part 51 away from its opening. When the second splicing pipe 21 abuts against the limiting ring 512, the threaded hole 211 aligns with the mounting hole 511. Under the action of the limiting ring 512, it is easy to align the threaded hole 211 with the mounting hole 511, thereby improving the installation efficiency of the second splicing pipe 21 and the second splicing component 5.

[0044] like Figure 1 As shown, the first splicing part 4 is a three-way structure. The two opposite ends of the first splicing part 4 are respectively threaded on the outside of the first splicing pipe 11, and the other end is the docking end. The docking end is embedded in one end of the corresponding second splicing part 5, and the corresponding connecting bolt 52 can slide through the connecting part 51 and then be threaded into the docking end; the electric damper 31 is set at the docking end.

[0045] like Figure 1 As shown, the air inlet of the blower 3 is provided with a three-way pipe 7. The first end of the three-way pipe 7 is connected to the air inlet of the blower 3. The second end of the three-way pipe 7 is provided with a first switch valve 71. The third end of the three-way pipe 7 is provided with a drying box 8, and the third end of the three-way pipe 7 is connected to the drying box 8 through a second switch valve 72.

[0046] A humidity sensor 63 is installed inside the mounting tube 61, and the probe of the humidity sensor 63 extends outside the mounting tube 61. The humidity sensor 63, the first switching valve 71, and the second switching valve 72 are electrically connected to the controller.

[0047] The humidity sensor 63 detects the humidity inside the beet pile. When the humidity exceeds a threshold, the controller activates the blower 3 and the corresponding electric damper 31. Simultaneously, it closes the first valve 71 and opens the second valve 72, allowing outside air to pass through the desiccant in the desiccant box 82 for dehumidification. This introduces dry air into the beet pile, reducing humidity and preventing free water on the beet root surface from causing parasitic bacteria to flow and invade healthy tissue, leading to rot. When the humidity is below the threshold, the controller opens the first valve 71 and closes the second valve 72, allowing the blower 3 to quickly deliver a large amount of cool air.

[0048] In this embodiment, humidity control has a higher priority than temperature control. When the humidity signal obtained by the humidity sensor 63 is greater than the threshold, and the beet pile temperature obtained by the corresponding temperature sensor is less than 8°C, the controller controls the corresponding electric damper 31 to open, and at the same time controls the first switching valve 71 to close and the second switching valve 72 to open.

[0049] like Figure 5As shown, the drying oven 8 includes a box body 81 and a moisture-absorbing box 82. The box body 81 has through openings 811 at both ends. One opening 811 is connected to the third end of the three-way pipe 7, and the other opening 811 is an air inlet. The inner walls of the box body 81 have sliding grooves 812 on opposite sides. The moisture-absorbing box 82 is slidably embedded into the box body 81 through the sliding grooves 812. The moisture-absorbing box 82 contains a desiccant. The top of the box body 81 has a lid 83, and the lid 83 is connected to the box body 81 through buckles 831 on both sides.

[0050] In this embodiment, multiple chutes 812 and moisture-absorbing boxes 82 are provided. The moisture-absorbing box 82 has a mesh frame structure, and the desiccant is silica gel desiccant. When the first switch valve 71 is closed and the second switch valve 72 is opened, and the blower 3 is started, outside air can pass through multiple moisture-absorbing boxes 82 to absorb moisture, thereby providing dry air to the beet pile. After the moisture-absorbing effect of the moisture-absorbing box 82 is lost, the moisture-absorbing box 82 can be replaced by opening the box cover 83.

[0051] like Figure 1 and Figure 6 As shown, it also includes a storage tank 9, which is used to store disinfectant. A booster pump 91 is installed inside the storage tank 9. A drain pipe 92 is provided at the drain end of the booster pump 91. One end of the drain pipe 92 is connected to the booster pump 91, and the other end extends out of the storage tank 9 and is equipped with an atomizing head 93. The atomizing head 93 is embedded in the end of the main air duct 1 near the blower 3. In this embodiment, the storage tank 9 is provided with a cover, which is threadedly connected to the storage tank 9. The disinfectant is added by opening the cover.

[0052] In this embodiment, the storage tank 9 contains sodium metabisulfite solution. The disinfectant solution, atomized by the atomizing head 93, is fed into the branch pipe 2 by the blower 3 and discharged through the air guide hole to disinfect the beet pile.

[0053] The beet ventilation and preservation device in this embodiment is used as follows:

[0054] Depending on the required size of the beet pile, select an appropriate number of first connecting pipes 11 and second connecting pipes 21. Connect the first connecting pipes 11 to the main air duct 1 using the first connecting piece 4, with one end connected to the blower 3 and the other end covered with a sealing cap. Connect the second connecting pipes 21 to the branch air ducts 2 using the second connecting piece 5, with one end of the branch air duct 2 connected to the second connecting pipe 21 using the second connecting piece 5, and the other end of the branch air duct 2 covered with a sealing cap. Beet stacking for storage should begin when the average temperature is ≤15℃, and the height of the beet pile should not exceed 3.5 meters, so that the branch air ducts 2 are buried at the bottom of the beet pile.

[0055] When the temperature of the beet pile obtained by the temperature sensor 62 is ≥8℃, the controller controls the blower 3 to open and the corresponding electric damper 31 to open, so that the cooler outside air can enter the beet pile; when the humidity data obtained by the humidity sensor 63 is greater than the threshold, the controller controls the blower 3 to open and the corresponding electric damper 31 to open, and at the same time controls the first switch valve 71 to close and the second switch valve 72 to open, so that the outside air is dehumidified by the desiccant in the desiccant box 82, so as to input dry air into the beet pile.

[0056] The booster pump 91 and blower 3 are started at preset intervals, and all electric dampers 31 are opened to quantitatively input the atomized disinfectant into the branch pipe 2 and discharge it through the air duct to disinfect the beet pile.

[0057] In this embodiment, a covering can also be laid:

[0058] When the daytime temperature is above 5℃ and the nighttime temperature is above 0℃, cover the stack with the white side facing up and the black side facing down. During the day, cover the top of the stack and the ventilation openings to prevent the stack from drying out in the sun and hot air from entering the stack. At night, uncover the top of the stack and the ventilation openings around the stack to allow for ventilation and cooling.

[0059] If the daytime temperature is above 0℃ and below 5℃, and the nighttime temperature is below 0℃, in order to prevent the beets from freezing, cover them with the black side facing up and the white side facing down. Uncover them during the day to allow for ventilation and cooling, and cover them at night to prevent freezing.

[0060] If the temperature is below 0℃ during both day and night, the black side up and the white side down should be kept covered and stored day and night.

[0061] In case of rain or snow, the beet stacks should be completely covered in advance to prevent rain or snow from getting inside.

[0062] When encountering cold weather (or nighttime temperatures below 0°C), cover the beets while harvesting to prevent them from freezing.
