Description

Technical Field

[0001] This utility model relates to the field of honeysuckle processing technology, and specifically discloses an integrated device for rapid blanching and low-temperature drying of fresh honeysuckle. Background Technology

[0002] Honeysuckle, as an important traditional Chinese medicine and health food ingredient, owes its quality largely to its post-harvest processing. Fresh honeysuckle has high enzyme activity after harvesting; if not processed promptly, it will undergo enzymatic browning, resulting in a yellowish color and a decline in appearance. Simultaneously, its core medicinal components (such as chlorogenic acid) and volatile aromatic substances will decompose and be lost in large quantities. Therefore, it is essential to rapidly deactivate enzymes through a blanching process and remove excess moisture through low-temperature drying to facilitate storage and transportation, and to lock in its color and active ingredients to the greatest extent possible.

[0003] Currently, existing technologies commonly employ a combination of steam blanching and conveyor belts for continuous blanching operations, followed by separate drying equipment. This approach presents two problems: First, the steam blanching process generates a large amount of high-temperature waste steam, which carries away most of the heat energy input from the blanching step. However, existing equipment typically vents this waste steam directly, failing to effectively recover and utilize this heat in the subsequent drying process, resulting in energy waste. Second, blanching and drying are generally completed in two separate sets of equipment. This not only increases the equipment footprint but also requires manual transfer of the blanched material, disrupting production continuity and increasing operational steps, thus impacting overall efficiency.

[0004] Therefore, an integrated device for rapid blanching and low-temperature drying of fresh honeysuckle is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes an integrated device for rapid blanching and low-temperature drying of fresh honeysuckle, which can recover the heat energy carried by the high-temperature waste gas generated during the steam blanching process and use it as a supplementary heat source for the hot air drying process, effectively reducing the overall energy consumption; at the same time, by integrating blanching and drying functions into a set of continuously operating equipment, the equipment footprint and operation procedures are reduced.

[0006] This utility model is implemented as follows: an integrated device for rapid blanching and low-temperature drying of fresh honeysuckle, including a conveying mechanism, a blanching and drying mechanism, and a heat conduction mechanism.

[0007] The conveying mechanism includes a base frame, with two drive rollers rotatably connected inside the base frame, and a conveyor belt drivingly connecting the two drive rollers. A drive motor with its output end fixedly connected to one of the drive rollers is installed on the outer wall of the base frame.

[0008] The blanching and drying mechanism includes a steam box fixedly connected inside the base frame. The upper end of the steam box is connected to multiple steam nozzles. A hot air box is fixedly connected inside the base frame. The lower end of the hot air box is connected to multiple hot air nozzles. A heat insulation cylinder is installed above the hot air box. The lower end of the heat insulation cylinder and the upper end of the hot air box are both connected to a fixed pipe. A honeycomb electric heater is installed between two of the fixed pipes. A blower is installed at the upper end of the heat insulation cylinder. A temperature sensor extending into the interior of the hot air box is installed on the outer wall of the hot air box.

[0009] The heat conduction mechanism includes a steam suction hood fixedly connected to the inside of the base frame, a heat conduction pipe fixedly connected to the top of the inner wall of the insulation cylinder, the air outlet of the blower extending into the interior of the heat conduction pipe, a spiral tube wound around the outer wall of the heat conduction pipe inside the insulation cylinder, a bend connecting one end of the spiral tube to the interior of the steam suction hood, a high-temperature resistant centrifugal fan located on the left side of the insulation cylinder, and a connecting pipe connecting the air inlet of the high-temperature resistant centrifugal fan to the other end of the spiral tube.

[0010] As a preferred embodiment of the integrated device for rapid blanching and low-temperature drying of fresh honeysuckle according to this utility model, the base frame is rotatably connected to two first guide rollers that abut against the outer wall of the conveyor belt, and the base frame is rotatably connected to two second guide rollers that abut against the inner wall of the conveyor belt, and the steam box is located inside the conveyor belt.

[0011] As a preferred embodiment of the integrated device for rapid blanching and low-temperature drying of fresh honeysuckle according to this utility model, the conveyor belt is a stainless steel mesh belt.

[0012] As a preferred embodiment of the integrated device for rapid blanching and low-temperature drying of fresh honeysuckle according to this utility model, a vertical plate is installed on the upper end of the base frame, and an operation panel and a PLC controller are installed on the outer wall of the vertical plate.

[0013] As a preferred embodiment of the integrated device for rapid blanching and low-temperature drying of fresh honeysuckle according to this utility model, a stabilizing plate is fixedly connected to the outer wall of the heat preservation cylinder, and the high-temperature resistant centrifugal fan is installed on the outer wall of the stabilizing plate.

[0014] As a preferred embodiment of the integrated device for rapid blanching and low-temperature drying of fresh honeysuckle according to this utility model, the outer wall of the base frame is fixedly connected with a steam connector extending into the steam box.

[0015] As a preferred embodiment of the integrated device for rapid blanching and low-temperature drying of fresh honeysuckle according to this utility model, mounting frames are fixedly connected to both the left and right sides of the lower end face of the base frame.

[0016] The beneficial effects of this utility model are:

[0017] 1. A high-temperature resistant centrifugal fan draws the high-temperature exhaust gas generated during steam blanching into a spiral tube, while a blower simultaneously introduces ambient air into the heat-conducting pipe. Because the spiral tube is wound around the outer wall of the heat-conducting pipe, the high-temperature exhaust gas flowing through the spiral tube efficiently transfers heat energy to the air flowing inside the heat-conducting pipe, thus achieving heat recovery from the exhaust gas. This preheated air then enters a honeycomb electric heater for secondary heating, ultimately serving as the heat source for the hot air drying process, effectively reducing the overall energy consumption of the system.

[0018] 2. The material is carried by a conveyor belt, passing sequentially through the steam blanching zone and the hot air drying zone, eliminating the need for intermediate transfers. The entire processing from blanching to drying can be completed on a single machine. This integrated design significantly reduces the equipment's footprint and operating procedures, thereby ensuring the integrity of the material's form and improving overall production efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-4 A device for rapid blanching and low-temperature drying of fresh honeysuckle includes a conveying mechanism, a blanching and drying mechanism, and a heat conduction mechanism.

[0027] The conveying mechanism includes a base frame 1, with two drive rollers 2 rotatably connected inside the base frame 1, and a conveyor belt 3 drivingly connected between the two drive rollers 2. A drive motor 4 with its output end fixedly connected to one of the drive rollers 2 is installed on the outer wall of the base frame 1.

[0028] The blanching and drying mechanism includes a steam box 7 fixedly connected inside the base frame 1. Multiple steam nozzles 8 are connected to the upper end of the steam box 7. A hot air box 10 is fixedly connected inside the base frame 1. Multiple hot air nozzles 11 are connected to the lower end of the hot air box 10. A heat preservation cylinder 18 is installed above the hot air box 10. Fixed pipes 17 are connected to the lower end of the heat preservation cylinder 18 and the upper end of the hot air box 10. A honeycomb electric heater 16 is installed between the two fixed pipes 17. A blower 21 is installed at the upper end of the heat preservation cylinder 18. A temperature sensor 12 extending into the outer wall of the hot air box 10 is installed.

[0029] The heat conduction mechanism includes a steam suction hood 14 fixedly connected to the inside of the base frame 1, a heat conduction pipe 19 fixedly connected to the top of the inner wall of the insulation cylinder 18, the air outlet of the blower 21 extending into the inside of the heat conduction pipe 19, a spiral tube 20 wound around the outer wall of the heat conduction pipe 19 inside the insulation cylinder 18, a bend 15 connecting one end of the spiral tube 20 to the inside of the steam suction hood 14, a high-temperature resistant centrifugal fan 13 on the left side of the insulation cylinder 18, and a connecting pipe 22 connecting the air inlet of the high-temperature resistant centrifugal fan 13 to the other end of the spiral tube 20.

[0030] In this embodiment: During operation, the drive motor 4 starts and drives the corresponding transmission roller 2 to rotate counterclockwise. Through the cooperation of the two transmission rollers 2, the conveyor belt 3 is driven to run continuously. The fresh honeysuckle to be processed is evenly spread on the conveyor belt 3 and passes through the blanching and drying work areas in sequence with the conveyor belt 3.

[0031] First, the material enters the steam blanching stage. An external steam source injects high-temperature steam into the steam box 7 through the steam connector 9. The steam is then evenly sprayed upwards onto the material on the conveyor belt 3 through the steam nozzle 8, achieving rapid blanching.

[0032] During the blanching process, the high-temperature exhaust gas is drawn into the suction hood 14 by the high-temperature resistant centrifugal fan 13. It then passes sequentially through the bend 15, spiral tube 20, and connecting pipe 22 before being discharged from the outlet of the high-temperature resistant centrifugal fan 13. Simultaneously, the blower 21 continuously blows ambient air into the heat-conducting pipe 19. Since the spiral tube 20 is wrapped around the outer wall of the heat-conducting pipe 19, when the high-temperature exhaust gas flows through the spiral tube 20, the heat it carries is transferred through the pipe wall to the air flowing inside the heat-conducting pipe 19. This recovers the heat energy carried by the high-temperature exhaust gas generated during the steam blanching process and uses it as a supplementary heat source for the hot air drying process, effectively reducing overall energy consumption.

[0033] The preheated air continues to flow to the honeycomb electric heater 16. Temperature sensor 12 monitors the temperature inside the hot air box 10 in real time and feeds it back to the PLC controller. The PLC controller adjusts the power of the honeycomb electric heater 16 in real time to reheat the preheated air, bringing it to the optimal low-temperature drying temperature. Finally, the hot air enters the hot air box 10 through the fixed pipe 17 and is blown onto the blanched material by the hot air nozzles 11 for drying. In summary, this device integrates blanching and drying functions into a single continuously operating unit, significantly reducing the equipment footprint and operating procedures, and improving production efficiency.

[0034] As a technical optimization of this utility model, the base frame 1 is internally rotatably connected to two first guide rollers 5 that abut against the outer wall of the conveyor belt 3, and the base frame 1 is internally rotatably connected to two second guide rollers 6 that abut against the inner wall of the conveyor belt 3. The steam box 7 is located inside the conveyor belt 3.

[0035] In this embodiment: two first guide rollers 5 abut against the outer wall of the conveyor belt 3, and two second guide rollers 6 abut against the inner wall of the conveyor belt 3, which together guide the running trajectory of the conveyor belt 3 and provide a space for the steam box 7.

[0036] As a technical optimization of this utility model, the conveyor belt 3 is a stainless steel mesh belt.

[0037] In this embodiment, a stainless steel mesh belt is used as the conveyor belt 3, which allows steam and hot air to penetrate the material layer, thereby improving the blanching and drying effects.

[0038] As a technical optimization of this utility model, a vertical plate is installed on the upper end of the base frame 1, and an operation panel and a PLC controller are installed on the outer wall of the vertical plate.

[0039] In this embodiment: the operation panel is used to set and display process parameters and send instructions. The PLC controller receives the instructions and controls the operation of the drive motor 4, the honeycomb electric heater 16, the high-temperature centrifugal fan 13 and the blower 21. The PLC controller is also responsible for receiving the feedback signal from the temperature sensor 12 and controlling the operating power of the honeycomb electric heater 16 according to the feedback signal.

[0040] As a technical optimization of this utility model, a stabilizing plate is fixedly connected to the outer wall of the heat preservation cylinder 18, and a high-temperature resistant centrifugal fan 13 is installed on the outer wall of the stabilizing plate.

[0041] In this embodiment, a stabilizing plate is provided to facilitate the installation and fixation of the high-temperature resistant centrifugal fan 13.

[0042] As a technical optimization of this utility model, a steam connector 9 extending into the steam box 7 is fixedly connected through the outer wall of the base frame 1.

[0043] In this embodiment: the steam connector 9, which is fixed to the outer wall of the base frame 1, serves as the interface for the external steam source, stably delivering high-temperature steam into the steam box 7, providing a continuous steam supply to the steam nozzle 8.

[0044] As a technical optimization of this utility model, mounting brackets are fixedly connected to both the left and right sides of the lower end face of the base frame 1.

[0045] In this embodiment, two mounting brackets are provided to facilitate the overall installation and fixation of the device.

[0046] The working principle and usage process of this utility model are as follows: During operation, the drive motor 4 starts and drives the corresponding transmission roller 2 to rotate counterclockwise. Through the cooperation of the two transmission rollers 2, the conveyor belt 3 is driven to run continuously. The fresh honeysuckle to be processed is evenly spread on the conveyor belt 3 and passes through the blanching and drying work areas in sequence with the conveyor belt 3.

[0047] First, the material enters the steam blanching stage. An external steam source injects high-temperature steam into the steam box 7 through the steam connector 9. The steam is then evenly sprayed upwards onto the material on the conveyor belt 3 through the steam nozzle 8, achieving rapid blanching.

[0048] During the blanching process, the high-temperature exhaust gas is drawn into the suction hood 14 by the high-temperature resistant centrifugal fan 13. It then passes sequentially through the bend 15, spiral tube 20, and connecting pipe 22 before being discharged from the outlet of the high-temperature resistant centrifugal fan 13. Simultaneously, the blower 21 continuously blows ambient air into the heat-conducting pipe 19. Since the spiral tube 20 is wrapped around the outer wall of the heat-conducting pipe 19, when the high-temperature exhaust gas flows through the spiral tube 20, the heat it carries is transferred through the pipe wall to the air flowing inside the heat-conducting pipe 19. This recovers the heat energy carried by the high-temperature exhaust gas generated during the steam blanching process and uses it as a supplementary heat source for the hot air drying process, effectively reducing overall energy consumption.

[0049] The preheated air continues to flow to the honeycomb electric heater 16. Temperature sensor 12 monitors the temperature inside the hot air box 10 in real time and feeds it back to the PLC controller. The PLC controller adjusts the power of the honeycomb electric heater 16 in real time to reheat the preheated air, bringing it to the optimal low-temperature drying temperature. Finally, the hot air enters the hot air box 10 through the fixed pipe 17 and is blown onto the blanched material by the hot air nozzles 11 for drying. In summary, this device integrates blanching and drying functions into a single continuously operating unit, significantly reducing the equipment footprint and operating procedures, and improving production efficiency.
