Description

Technical Field

[0001] The present invention relates to the technical field of Gongcai processing, and particularly relates to a Gongcai drying production line. Background Art

[0002] Gongcai is an annual herbaceous plant. It has bright green color, refreshing texture, and taste similar to jellyfish. It has extremely high edible value and a long cultivation history. It is a pure natural high-grade dehydrated vegetable. Because it was once presented to the court annually in ancient times, it was named "Gongcai"; and because it makes a crisp sound when eaten, it is vividly called "Xiangcai" or "Mountain Jellyfish".

[0003] During the processing, the fresh Gongcai after peeling and cutting needs to be dried to remove moisture, which is convenient for long-term storage and subsequent packaging and sales. The traditional operation method of the Gongcai drying production line is: evenly spread Gongcai on a breathable tray with holes at the bottom, and then transport the tray full of materials to the conveyor belt of a continuous drying device and send it into the device for drying.

[0004] However, there are significant differences in the requirements for drying conditions at different stages of the Gongcai drying process. In the initial stage of drying, the moisture content of Gongcai is relatively high. To improve the drying efficiency and maximize the single production capacity as much as possible, usually multiple trays need to be laid flat on the conveyor belt in the form of a rectangular array to increase the contact area between the materials and the hot air. In the later stage of drying, the moisture content of Gongcai decreases. To further improve the drying efficiency and single production capacity, multiple trays need to be stacked in the form of a rectangular array on the conveyor belt to make full use of the space volume of the drying chamber.

[0005] The existing drying production line has a fixed structure and cannot adjust the arrangement of trays according to different drying stages, resulting in the equipment being difficult to meet the best process requirements of both stages at the same time. This problem directly causes low drying efficiency and uneven heating of materials. Often, it needs to be dried repeatedly many times to meet the finished product requirements, increasing energy consumption and labor cost. In addition, the existing drying line cannot achieve self-loading of trays. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above technical deficiencies and propose a Gongcai drying production line to solve the technical problems in the prior art that the drying production line has a fixed structure and cannot adjust the arrangement of trays according to different drying stages, resulting in low drying efficiency, uneven heating of materials, and the need to be dried repeatedly many times to meet the finished product requirements. In addition, it cannot achieve self-loading of trays.

[0007] To achieve the above technical purpose, the technical solution of the present invention provides a Gongcai drying production line, including: Two drying units, each including a housing, a first conveying mechanism and an air supply mechanism, the housing having a drying chamber with openings at both ends along its length, the first conveying mechanism being disposed inside the drying chamber for conveying a tray along the length of the drying chamber, and the outlet end of the air supply mechanism being connected to the drying chamber for blowing hot air into the drying chamber. The first feeding unit, located at the inlet end of the first conveying mechanism, is used to arrange multiple pallets in a row along the width direction of the first conveying mechanism on the first conveying mechanism; and The second feeding unit is located between the two first conveying mechanisms and is used to stack multiple rows of pallets arriving at the outlet end of the first conveying mechanism at the first position onto the first conveying mechanism at the rear position.

[0008] Furthermore, the box is provided with multiple partitions, each of which is spaced apart along the length of the drying chamber to divide the drying chamber into multiple drying zones. The partitions are provided with slots for the first conveying mechanism and the tray to pass through.

[0009] Furthermore, the air supply mechanism includes multiple units, and the outlet end of each air supply mechanism is connected to each of the drying zones in a one-to-one correspondence, so as to blow air into the drying zone from top to bottom or from bottom to top.

[0010] Furthermore, the air supply mechanism includes an air supply component and a heat exchange component. The outlet end of the air supply component is connected to the top or bottom of the drying chamber to blow air into the drying chamber. The heat exchange component is disposed inside the chamber, and the steam inside it can exchange heat with the air flow inside the chamber to increase the air temperature.

[0011] Furthermore, the air supply assembly is disposed inside the drying chamber and located to the side of the first conveying mechanism. It includes an air inlet pipe and an exhaust fan. One end of the air inlet pipe extends out of the housing. The inlet end of the exhaust fan is connected to the other end of the air inlet pipe. The outlet end of the exhaust fan is connected to the space above or below the first conveying mechanism to blow air into the space above or below the first conveying mechanism.

[0012] Furthermore, the drying unit also includes a dehumidification mechanism, the inlet of which is connected to the drying chamber to extract the air with high humidity from the drying chamber.

[0013] Furthermore, the dehumidification mechanism includes an exhaust fan and a dehumidification pipe. The inlet end of the exhaust fan is connected to the drying chamber, and the outlet end of the exhaust fan is connected to one end of the dehumidification pipe, so as to draw the air with higher humidity in the drying chamber into the dehumidification pipe.

[0014] Furthermore, the first feeding unit includes a second conveying mechanism, a first suction mechanism, a first lifting mechanism, a first X-axis moving mechanism, and a first Y-axis moving mechanism. The second conveying mechanism is used to convey each pallet so that each pallet arrives at its end feeding station in sequence. The first suction mechanism is used to suction or release a single pallet at the feeding station. The first lifting mechanism is connected to the first suction mechanism and is used to drive the first suction mechanism to move up and down. The first X-axis moving mechanism is connected to the first lifting mechanism and is used to drive the first lifting mechanism to move horizontally back and forth along the width direction of the first conveying mechanism. The first Y-axis moving mechanism is connected to the first X-axis moving mechanism and is used to drive the first X-axis moving mechanism to move horizontally back and forth along the length direction of the first conveying mechanism.

[0015] Furthermore, the second feeding unit includes a second suction mechanism, a second lifting mechanism, and a second Y-axis moving mechanism.

[0016] Furthermore, the dried gongcai production line also includes multiple air blowing units, each of which is linearly distributed above the second conveying mechanism along the length of the second conveying mechanism, and is used to blow air onto the trays on the second conveying mechanism to perform preliminary air drying on the gongcai on the trays.

[0017] Compared with the prior art, the beneficial effects of the present invention include: In use, multiple trays are arranged in a row along the width direction of the first conveying mechanism by the first feeding unit and placed on the first conveying mechanism at the first position. The first conveying mechanism at the first position transports the trays to the corresponding drying chambers for drying. The arrangement of multiple trays along the width direction of the first conveying mechanism increases the contact area between the dried vegetables and the hot air, improves drying efficiency, and maximizes the single-batch capacity. The multiple rows of trays arriving at the outlet of the first conveying mechanism at the first position are stacked and placed on the first conveying mechanism at the rear position by the second feeding unit. The first conveying mechanism at the rear position transports the trays to the corresponding drying chambers for drying. The stacking of multiple rows of trays can make full use of the space volume of the drying chamber, further improving drying efficiency and single-batch capacity. This dried vegetable drying production line can adjust the arrangement of the trays according to different drying stages, which can simultaneously meet the optimal process requirements before and after the dried vegetables are dried, ensuring uniform heating of the material while improving drying efficiency, reducing energy consumption and labor costs, and realizing automatic, precise, and efficient tray arrangement and feeding.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0020] This invention provides a drying production line for dried gongcai (a type of dried vegetable), the structure of which is as follows: Figure 1 - Figure 6 As shown, the device includes two drying units 100, a first feeding unit 200, and a second feeding unit 300. Each drying unit 100 includes a housing 110, a first conveying mechanism 120, and an air supply mechanism 130. The housing 110 has a drying chamber 111 with openings at both ends along its length. The first conveying mechanism 120 is located within the drying chamber 111 and is used to convey trays 1 along the length of the drying chamber 111. The outlet end of the air supply mechanism 130 is connected to the drying chamber 111 and is used to blow hot air into the drying chamber 111. The first feeding unit 200 is located at the inlet end of the first conveying mechanism 120 and is used to arrange multiple trays 1 in a row along the width of the first conveying mechanism 120 on the first conveying mechanism 120. The second feeding unit 300 is located between the two first conveying mechanisms 120 and is used to stack multiple rows of trays 1 arriving at the outlet end of the first conveying mechanism 120 onto the second first conveying mechanism 120.

[0021] In use, the first feeding unit 200 arranges multiple trays 1 in a row along the width of the first conveying mechanism 120 and places them on the first conveying mechanism 120. The first conveying mechanism 120 then transports the trays 1 to the corresponding drying chambers 111 for drying. Arranging multiple trays 1 in a row along the width of the first conveying mechanism 120 increases the contact area between the dried vegetables and the hot air, improves drying efficiency, and maximizes the single-batch capacity. The second feeding unit 300 then stacks the multiple rows of trays 1 that have arrived at the outlet of the first conveying mechanism 120 and places them on the rear shelf. On the first conveyor mechanism 120 of the first position, the first conveyor mechanism 120 of the second position conveys the tray 1 to the corresponding drying chamber 111 for drying. Multiple rows of trays 1 are stacked and placed, which can make full use of the space volume of the drying chamber 111, further improving drying efficiency and single-batch capacity. This dried vegetable drying production line can adjust the arrangement of trays 1 according to different drying stages, which can simultaneously meet the optimal process requirements before and after the dried vegetable drying stages, ensure that the material is heated evenly, improve drying efficiency, reduce energy consumption and labor costs, and realize automatic, precise and efficient arrangement and feeding of trays 1.

[0022] In a preferred embodiment, the first conveying mechanism 120 is a mesh belt conveyor or a mesh chain conveyor, which is ventilated to ensure that air can pass through the first conveying mechanism 120 from top to bottom.

[0023] In a preferred embodiment, the housing 110 is provided with multiple partitions, which are spaced apart along the length of the drying chamber 111 to divide the drying chamber 111 into multiple drying zones. The partitions are provided with slots for the first conveying mechanism 120 and the tray 1 to pass through, thereby enabling segmented drying.

[0024] As a preferred embodiment, please refer to Figure 2 and Figure 3 The air supply mechanism 130 includes multiple units, and the outlet end of each air supply mechanism 130 is connected to each drying zone in a corresponding manner to blow air into the drying zone from top to bottom or from bottom to top, so as to dry the dried vegetables in each drying zone in a segmented manner.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 3 The outlet ends of adjacent air supply mechanisms 130 are respectively connected to the top and bottom of the drying chamber 111, so that air flows from top to bottom or from bottom to top in the drying chamber 111, and the flow directions of adjacent air flows are opposite. The first conveying mechanism 120 conveys the tray 1 to the corresponding drying chamber 111 for drying, so that the preserved vegetables on the tray 1 pass through each drying zone in sequence, that is, the preserved vegetables on the tray 1 pass through each air supply mechanism 130 in sequence. Since the outlet ends of adjacent air supply mechanisms 130 are respectively connected to the top and bottom of the drying chamber 111, they are used to supply air into the drying chamber 111. Hot air is blown in so that the air flows from top to bottom or from bottom to top in the drying chamber 111, and the flow direction of adjacent air flows is opposite. Therefore, the flow direction of hot air in adjacent drying zones is from top to bottom and from bottom to top, respectively, which can alternately dry both sides of the dried vegetables. In the drying unit 100 of this dried vegetable drying production line, the hot air flow direction is alternately bidirectional during the drying process of dried vegetables, which can efficiently dry both sides of the dried vegetables. The drying method of heating both sides can ensure that the dried vegetables are dried in a consistent manner, ensuring the uniformity of drying and improving the final quality of the product.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3 The adjacent air supply mechanisms 130 are staggered vertically, so that the outlet ends of the adjacent air supply mechanisms 130 are connected to the top and bottom of the drying chamber 111 respectively, ensuring that the hot air flows from top to bottom and from bottom to top in the adjacent drying zones respectively.

[0027] As a preferred embodiment, please refer to Figure 3 and Figure 4The air supply mechanism 130 includes an air supply component 131 and a heat exchange component 132. The outlet end of the air supply component 131 is connected to the top or bottom of the drying chamber 111 to blow air into the drying chamber 111. The heat exchange component 132 is disposed inside the housing 110, and the steam inside it can exchange heat with the air flow inside the housing 110 to increase the air temperature. Air can be blown into the drying chamber 111 through the air supply component 131, and the air can flow from top to bottom or from bottom to top in the drying chamber 111. The steam in the heat exchange component 132 can exchange heat with the circulating air in the drying chamber 111 to increase the air temperature. During the process of the higher temperature air flowing from top to bottom or from bottom to top in the drying chamber 111, the dried vegetables on the first conveying mechanism 120 can be dried. The steam heat exchange method can improve the uniformity of air heating and ensure the stability of temperature rise.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 An air supply assembly 131 is disposed inside the drying chamber 111 and located to the side of the first conveying mechanism 120. It includes an air inlet pipe 1311 and an exhaust fan 1312. One end of the air inlet pipe 1311 extends outside the housing 110. The inlet end of the exhaust fan 1312 is connected to the other end of the air inlet pipe 1311. The outlet end of the exhaust fan 1312 is connected to the space above or below the first conveying mechanism 120 to blow air into the space above or below the first conveying mechanism 120. When the exhaust fan 1312 is started, it can draw outside air into the drying chamber 111 through the air inlet pipe 1311 and make the air flow from top to bottom or from bottom to top in the drying chamber 111.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4 The heat exchange assembly 132 includes a heat exchange box 1321, an air inlet pipe 1322, a water outlet pipe 1323, a regulating valve 1324, a drain valve 1325, and an air source. The outlet end of the heat exchange box 1321 corresponds to the outlet end of the exhaust fan 1312. The outlet end of the air inlet pipe 1322 is connected to the inlet end of the heat exchange box 1321, and the inlet end of the water outlet pipe 1323 is connected to the outlet end of the heat exchange box 1321. The regulating valve 1324 is located at the inlet end of the heat exchange box 1321 to control the opening degree of the inlet end of the heat exchange box 1321, thereby regulating the air supply. The air intake and drain valve 1325 are located at the outlet end of the heat exchange box 1321 to control the opening and closing of the outlet end of the heat exchange box 1321. The outlet end of the air source is connected to the inlet end of the air intake pipe 1322 to introduce steam into the air intake pipe 1322. By controlling the regulating valve 1324, the opening degree of the inlet end of the heat exchange box 1321 can be controlled, thereby adjusting the air intake and controlling the heat exchange temperature. This ensures that the temperature of the air flow in the corresponding drying zone reaches the preset value, achieving precise and controllable air temperature. The air source is not shown in the figure.

[0030] As a preferred embodiment, the steam provided by the gas source can be steam generated by heating water in a boiler, or steam obtained by other means, which will not be elaborated on in this solution.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 3 The drying unit 100 also includes a dehumidification mechanism 140. The inlet end of the dehumidification mechanism 140 is connected to the drying chamber 111 to extract the air with high humidity in the drying chamber 111, so as to ensure that the air humidity in the drying chamber 111 is always within a suitable range and to ensure the drying effect.

[0032] As a preferred embodiment, please refer to Figure 2 and Figure 3 The dehumidification mechanism 140 includes multiple dehumidification mechanisms 140, which are spaced apart along the length of the drying chamber 111 to improve the dehumidification effect.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 3 The dehumidification mechanism 140 includes an exhaust fan 141 and a dehumidification pipe 142. The inlet end of the exhaust fan 141 is connected to the drying chamber 111, and the outlet end of the exhaust fan 141 is connected to one end of the dehumidification pipe 142. The exhaust fan 141 is used to draw the humid air in the drying chamber 111 into the dehumidification pipe 142. When the exhaust fan 141 is started, the exhaust fan 141 can draw out the humid air in the drying chamber 111 through the dehumidification pipe 142.

[0034] As a preferred embodiment, please refer to Figure 2 and Figure 3 The other end of the exhaust pipe 142 is connected to the workshop, so that the air with high humidity in the drying chamber 111 can be drawn into the workshop for use, which can humidify the air in the workshop and prevent the air in the workshop from drying out.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 5The first feeding unit 200 includes a second conveying mechanism 210, a first suction mechanism 220, a first lifting mechanism 230, a first X-axis moving mechanism 240, and a first Y-axis moving mechanism 250. The second conveying mechanism 210 is used to convey each pallet 1 so that each pallet 1 arrives at its end feeding station in sequence. The first suction mechanism 220 is used to suction or release a single pallet 1 at the feeding station. The first lifting mechanism 230 is connected to the first suction mechanism 220 and is used to drive the first suction mechanism 220 to move up and down. The first X-axis moving mechanism 240 is connected to the first lifting mechanism 230 and is used to drive the first lifting mechanism 230 to move horizontally back and forth along the width direction of the first conveying mechanism 120. The first Y-axis moving mechanism 250 is connected to the first X-axis moving mechanism 240 and is used to drive the first X-axis moving mechanism 240 to move horizontally back and forth along the length direction of the first conveying mechanism 120. In use, the second conveying mechanism 210 linearly conveys each pallet 1, allowing each pallet 1 to move sequentially... The first lifting mechanism 230 drives the first suction mechanism 220 to move downwards until the first suction mechanism 220 approaches the pallet 1 at the loading station. Then, the first suction mechanism 220 picks up the pallet 1. The first lifting mechanism 230 drives the first suction mechanism 220 to move upwards. The first X-axis moving mechanism 240 drives the first lifting mechanism 230 to move horizontally back and forth along the width direction of the first conveying mechanism 120. The first Y-axis moving mechanism 250 drives the first X-axis moving mechanism 240 to move horizontally back and forth along the length direction of the first conveying mechanism 120. This allows the pallet 1 picked up by the first suction mechanism 220 to reach the preset position of the first conveying mechanism 120. Then, the first lifting mechanism 230 drives the first suction mechanism 220 to move downwards, so that the pallet 1 contacts the first conveying mechanism 120. The first suction mechanism 220 releases the pallet 1, completing the loading process. The first loading unit 200 can replace manual labor and realize the automatic, accurate, and efficient loading of the pallet 1.

[0036] In a preferred embodiment, the second conveying mechanism 210 is a belt conveyor or a roller conveyor.

[0037] As a preferred embodiment, please refer to Figure 5 and Figure 6 The tray 1 is made of iron. The first suction mechanism 220 includes a first mounting frame 221 and a plurality of first electromagnets 222. Each first electromagnet 222 is detachably and fixedly connected to the first mounting frame 221. Each first electromagnet 222 is magnetic when de-energized, so as to attract each edge or corner of the tray 1. Each first electromagnet 222 loses its magnetism when energized, so as to release each edge or corner of the tray 1. The first lifting mechanism 230 is fixedly connected to the first mounting frame 221. This suction method can effectively attract the tray 1 and ensure the attraction strength.

[0038] As a preferred embodiment, please refer to Figure 6 and Figure 7 The first suction mechanism 220 also includes multiple first connectors 223. The top of each first connector 223 is detachably and fixedly connected to the first mounting bracket 221. Each first electromagnet 222 is detachably and fixedly connected to the bottom of each first connector 223. The first connector 223 has an elastic structure so that the first electromagnet 222 can swing when it hits the tray 1. Since the bottom surfaces of each first electromagnet 222 cannot be completely in the same horizontal plane, and the bottom surfaces of each first electromagnet 222 may also have a certain tilt angle, by setting the first connector 223 with an elastic structure, each first electromagnet 222 can swing to a certain extent when it hits the tray 1, ensuring that the bottom surfaces of each first electromagnet 222 can effectively abut against the tray 1, thereby ensuring the adsorption effect and strength.

[0039] In a preferred embodiment, the first suction mechanism 220 further includes a first power supply component, which is electrically connected to each of the first electromagnets 222 so that each of the first electromagnets 222 is simultaneously energized or de-energized. The first power supply component can supply power to each of the first electromagnets 222 at the same time, or de-energize each of the first electromagnets 222 at the same time, to ensure the normal operation of the attraction or release action of the first electromagnets 222.

[0040] In a preferred embodiment, the first power supply component includes a power supply, wires, and a circuit breaker. One end of each first electromagnet 222 is electrically connected to the positive terminal of the power supply via a wire, and the other end of each first electromagnet 222 is electrically connected to the negative terminal of the power supply via a wire. The circuit breaker is installed on the main incoming or outgoing line of each first electromagnet 222 to simultaneously control the conduction or interruption of each line. By operating the circuit breaker, the conduction or interruption of each line can be controlled simultaneously, so that each first electromagnet 222 is simultaneously energized or de-energized.

[0041] As a preferred embodiment, the first suction mechanism 220 can also use a vacuum suction cup to perform the action of suctioning or releasing the tray 1.

[0042] As a preferred embodiment, please refer to Figure 7 and Figure 8The first lifting mechanism 230 includes a mounting base 231, a first vertical beam 232, a first vertical rack 233, a first gear, and a first rotation drive component 234.

The first vertical rack 233 is vertically arranged and fixedly connected to the first vertical beam 232. The first gear meshes with the first vertical rack 233. The fixed end of the first rotation drive component 234 is fixedly connected to the mounting base 231. The output end of the drive member 234 is coaxially and fixedly connected to the first gear, which is used to drive the first gear to rotate so that the first vertical beam 232 moves up and down. When the first drive member 234 is activated, the output end of the first drive member 234 rotates in the forward or reverse direction, driving the first gear to rotate in the forward or reverse direction. According to the gear and rack meshing transmission principle, when the first gear rotates in the forward or reverse direction, the first vertical rack 233 will move up or down, that is, the first vertical beam 232 can move up or down, realizing the upward or downward movement of the first suction mechanism 220.

[0043] In another embodiment, the first lifting mechanism 230 may also be selected from a suitable type of first cylinder and directly connected to the first mounting bracket 221.

[0044] As a preferred embodiment, please refer to Figure 7 and Figure 8 The first X-axis moving mechanism 240 includes a first X-axis horizontal beam 241, a first moving seat 242, a first X-axis horizontal rack 243, a second gear, and a second rotational drive 244. The first X-axis horizontal beam 241 is horizontally arranged along the width direction of the first conveying mechanism 120. The first moving seat 242 is slidably connected to the first X-axis horizontal beam 241 and is also connected to the first lifting mechanism 230. The first X-axis horizontal rack 243 is horizontally arranged along the width direction of the first conveying mechanism 120 and is fixedly connected to the first X-axis horizontal beam 241. The second gear meshes with the first X-axis horizontal rack 243. The second rotational drive 244 is fixedly connected to the first X-axis horizontal beam 241. The first moving seat 242 is fixedly connected to the first moving seat 242. The output end of the second rotating drive 244 is fixedly connected to the second gear on the same axis. It is used to drive the second gear to rotate so that the first moving seat 242 moves horizontally back and forth along the width direction of the first conveying mechanism 120. When the second rotating drive 244 is started, the output end of the second rotating drive 244 rotates in the forward or reverse direction, driving the second gear to rotate in the forward or reverse direction. According to the gear and rack meshing transmission principle, when the second gear rotates in the forward or reverse direction, the first moving seat 242 will move horizontally back and forth along the width direction of the first conveying mechanism 120, so as to realize the first lifting mechanism 230 moving horizontally back and forth along the width direction of the first conveying mechanism 120.

[0045] In another embodiment, the first X-axis moving mechanism 240 may also adopt a lead screw and nut structure.

The second moving seat 252 is slidably connected to the first Y-axis horizontal beam 251 and is also connected to the first X-axis moving mechanism 240. The first Y-axis horizontal rack 253 is horizontally arranged along the length direction of the first conveying mechanism 120 and is fixedly connected to the first Y-axis horizontal beam 251.

[0051] As a preferred embodiment, please refer to Figure 9The second feeding unit 300 includes a second suction mechanism 310, a second lifting mechanism 320, and a second Y-axis moving mechanism 330. The second suction mechanism 310 is used to pick up or release a row of trays 1 at the outlet end of the first conveying mechanism 120. The second lifting mechanism 320 is connected to the second suction mechanism 310 and is used to drive the second suction mechanism 310 to move up and down. The second Y-axis moving mechanism 330 is connected to the second lifting mechanism 320 and is used to drive the second lifting mechanism 320 to move horizontally reciprocally along the length direction of the first conveying mechanism 120. The second lifting mechanism 320 drives the second suction mechanism 310 to move downward until the second suction mechanism 310 approaches the outlet end of the first conveying mechanism 120. At the inlet end, the second suction mechanism 310 then picks up a row of pallets 1. The second lifting mechanism 320 drives the second suction mechanism 310 to move upward, and the second Y-axis moving mechanism 330 drives the second lifting mechanism 320 to move horizontally back and forth along the length direction of the first conveying mechanism 120, so that the pallets 1 picked up by the second suction mechanism 310 reach the preset position of the first conveying mechanism 120 behind. Then, the second lifting mechanism 320 drives the second suction mechanism 310 to move downward, so that the pallets 1 contact the first conveying mechanism 120 behind. The second suction mechanism 310 releases the pallets 1, completing the feeding process. The second feeding unit 300 can replace manual labor and realize the automatic, accurate and efficient arrangement and feeding of pallets 1.

[0054] In a preferred embodiment, the second Y-axis moving mechanism 330 has the same structure as the first Y-axis moving mechanism 250, and will not be described in detail in this solution.

[0055] As a preferred embodiment, please refer to Figure 5 The dried vegetable drying production line also includes multiple air blowing units 400. Each air blowing unit 400 is linearly distributed above the second conveying mechanism 210 along the length direction of the second conveying mechanism 210. It is used to blow air onto the tray 1 on the second conveying mechanism 210 to pre-dry the dried vegetables on the tray 1, which can improve the drying effect and efficiency of the dried vegetables on the tray 1.

[0056] As a preferred embodiment, please refer to Figure 5The blower unit 400 includes a bracket 410 and a blower 420. The blower 420 is fixedly connected to the bracket 410, and the air outlet of the blower 420 faces the conveying surface of the second conveying mechanism 210. Since the blower 420 can blow air onto the tray 1 on the second conveying mechanism 210, the dried vegetables on the tray 1 can be preliminarily dried.

[0057] To better understand this invention, the following is combined with... Figure 1 - Figure 9 The working principle of the technical solution of the present invention will be described in detail below: In use, the second conveying mechanism 210 linearly conveys each pallet 1, allowing each pallet 1 to sequentially reach its end loading station. Then, the first lifting mechanism 230 drives the first suction mechanism 220 to move downwards until the first suction mechanism 220 approaches the pallet 1 at the loading station. Next, the first suction mechanism 220 picks up the pallet 1. The first lifting mechanism 230 drives the first suction mechanism 220 to move upwards, and the first X-axis moving mechanism 240 drives the first lifting mechanism 230 to move horizontally back and forth along the width direction of the first conveying mechanism 120. The first Y-axis moving mechanism 250 drives the first X-axis moving mechanism 240 to move horizontally back and forth along the length direction of the first conveying mechanism 120, allowing the pallet 1 picked up by the first suction mechanism 220 to reach... At the preset position of the first conveying mechanism 120, the first lifting mechanism 230 drives the first suction mechanism 220 to move downward, so that the tray 1 contacts the first conveying mechanism 120. The first suction mechanism 220 releases the tray 1, completing the feeding process. The first feeding unit 200 can replace manual labor, realizing automatic, precise, and efficient feeding of the tray 1. The first feeding unit 200 forms a row of multiple trays 1 along the width direction of the first conveying mechanism 120 and lays them on the first conveying mechanism 120. The first conveying mechanism 120 transports the trays 1 to the corresponding drying chamber 111 for drying. The multiple trays 1 forming a row along the width direction of the first conveying mechanism 120 can increase the contact area between the dried vegetables and the hot air, improving the drying efficiency. To maximize single-batch capacity, the first conveying mechanism 120 transports the tray 1 to the corresponding drying chamber 111 for drying. This allows the preserved vegetables on the tray 1 to pass through each drying zone sequentially, i.e., through each air supply mechanism 130 sequentially. Since the outlets of adjacent air supply mechanisms 130 are connected to the top and bottom of the drying chamber 111 respectively, hot air is blown into the drying chamber 111, causing the air to flow from top to bottom or from bottom to top within the drying chamber 111, and making the flow directions of adjacent airflows opposite. Therefore, the hot air flow directions in adjacent drying zones are respectively from top to bottom and from bottom to top, allowing for alternating drying of both sides of the preserved vegetables. In this preserved vegetable drying production line, the drying unit 100, during the drying process, directs the hot air flow in the direction of... The alternating bidirectional cycle allows for efficient drying of both sides of the dried vegetables. This double-sided heating method ensures consistent drying throughout, guaranteeing uniform drying and improving the final product quality. The second lifting mechanism 320 drives the second suction mechanism 310 downwards until it approaches the outlet of the first conveying mechanism 120. Then, the second suction mechanism 310 picks up a row of trays 1. The second lifting mechanism 320 then drives the second suction mechanism 310 upwards. The second Y-axis moving mechanism 330 drives the second lifting mechanism 320 to move horizontally back and forth along the length of the first conveying mechanism 120, allowing the trays 1 picked up by the second suction mechanism 310 to reach a preset position on the rear first conveying mechanism 120.Next, the second lifting mechanism 320 drives the second suction mechanism 310 to move downwards, causing the tray 1 to contact the rear first conveying mechanism 120. The second suction mechanism 310 releases the tray 1, completing the feeding process. The second feeding unit 300 can replace manual labor, realizing automatic, precise, and efficient tray 1 arrangement and feeding. Through the second feeding unit 300, multiple rows of trays 1 arriving at the outlet of the first conveying mechanism 120 are stacked and placed on the rear first conveying mechanism 120. The rear first conveying mechanism 120 transports the trays 1 to the corresponding drying chamber 111 for drying. The stacking of multiple rows of trays 1 can fully utilize the space volume of the drying chamber 111, further improving drying efficiency and single-batch capacity. This dried vegetable drying production line can adjust the arrangement of the trays 1 according to different drying stages, simultaneously meeting the optimal process requirements before and after the dried vegetable drying stages, ensuring uniform heating of the material while improving drying efficiency, reducing energy consumption and labor costs, and realizing automatic, precise, and efficient tray 1 arrangement and feeding.

[0058] The dried vegetable drying production line provided by this invention has the following beneficial effects: (1) By controlling the regulating valve 1324, the opening degree of the inlet end of the heat exchange box 1321 can be controlled, thereby adjusting the air intake and controlling the heat exchange temperature, ensuring that the temperature of the air flow in the corresponding drying zone reaches the preset value, and achieving precise control of the air temperature. (2) In the drying unit 100 of this dried vegetable production line, the hot air flow direction is alternating bidirectional circulation during the drying process of dried vegetables, which can efficiently dry both sides of the dried vegetables. The drying method of heating both sides can ensure that the dried vegetables are dried in a consistent manner, ensuring the uniformity of drying and improving the final quality of the product. (3) This dried vegetable drying production line can adjust the arrangement of tray 1 according to different drying stages, which can simultaneously meet the optimal process requirements before and after the dried vegetable drying stages, ensure uniform heating of materials, improve drying efficiency, reduce energy consumption and labor costs, and realize automatic, precise and efficient arrangement of tray 1 for feeding.

Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
