Description

Technical Field

[0001] This utility model relates to the field of ginkgo processing equipment technology, and in particular to a ginkgo leaf drying and shaping device. Background Technology

[0002] In the processing of ginkgo leaves, drying and shaping are necessary to remove moisture and extend their shelf life while preserving their active ingredients and form, facilitating further processing such as making ginkgo leaf tea or extracting medicinal components.

[0003] Traditional methods of drying ginkgo leaves primarily involve natural air drying or simple hot air drying. While natural air drying is less expensive, it is highly susceptible to weather conditions. In rainy weather, ginkgo leaves cannot dry quickly enough, making them prone to mold and spoilage, resulting in significant losses. Furthermore, natural air drying is time-consuming and inefficient, failing to meet the demands of large-scale production.

[0004] A simple hot air drying method typically involves setting up a heating device in a relatively enclosed space to generate hot air, and then placing the ginkgo leaves inside for drying. However, this method has several drawbacks. Firstly, the hot air distribution is uneven; ginkgo leaves near the heating device are prone to over-drying or even scorching, while those further away are under-dried, resulting in inconsistent drying quality and damage to the effective components due to localized overheating. Secondly, traditional drying equipment lacks effective airflow circulation and dehumidification systems, preventing timely removal of moisture and creating a high-humidity drying environment. This further prolongs the drying time, reduces drying efficiency, and increases energy consumption. Utility Model Content

[0005] The purpose of this invention is to provide a ginkgo leaf drying and shaping device that solves the problems of traditional ginkgo leaf drying being affected by weather, uneven drying quality, and inefficient dehumidification.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A ginkgo leaf drying and shaping device includes a cabinet, an upper air chamber and a lower air chamber inside the cabinet, an air inlet at the top of the cabinet that communicates with the upper air chamber, symmetrical exhaust vents at the bottom of the cabinet that communicate with the lower air chamber, guide cavities on both sides and in the middle of the cabinet interior, several guide cavities dividing the interior of the cabinet into two drying zones, the bottom of each guide cavity communicating with the lower air chamber, support rails fixedly connected at equal intervals on both sides of the drying zone, trays equidistantly placed inside the drying zone, the bottom sides of each tray slidingly connected to the corresponding support rails, and exhaust vents at corresponding locations on the top of the guide cavities and trays.

[0007] Preferably, an air intake fan is fixedly installed inside the upper air chamber directly below the air inlet, and heating lamps are fixedly installed on both sides of the air intake fan inside the upper air chamber. Symmetrical connecting ports are provided at the bottom of the upper air chamber, and the upper air chamber is connected to the drying zone through the connecting ports. The air intake fan introduces outside air into the upper air chamber, the heating lamps heat the incoming air, and the connecting ports allow the heated air to enter the drying zone, providing a stable heat source for drying ginkgo leaves.

[0008] Preferably, the lower air chamber is equipped with a partition, and exhaust fans are fixedly installed at equal intervals at the bottom of the partition. Two guide plates are fixedly connected between the top of the partition and the inner wall of the top of the upper air chamber. The two guide plates separate the area above the exhaust fans, and each exhaust fan is connected to a guide cavity. The partition, exhaust fans and guide plates work together to quickly draw out the moisture in the drying area through the guide cavity and discharge it from the exhaust port, forming an efficient airflow circulation and accelerating drying.

[0009] Preferably, cabinet doors are symmetrically connected to both sides of the cabinet body, and a sealing strip is provided on one edge of the cabinet door. The cabinet door is easy to open and close for operations such as loading and unloading ginkgo leaves. The sealing strip prevents hot air leakage and external impurities from entering, ensuring a stable drying environment.

[0010] Preferably, the bottom of the tray has symmetrical hand pull grooves, which provide a leverage point for the operator to easily move the tray, making it convenient to load and unload ginkgo leaves and adjust the position of the tray.

[0011] Preferably, a pressure net is placed inside the tray to fix the position of the ginkgo leaves inside the tray, preventing them from moving under the blowing of hot air and ensuring that the ginkgo leaves are heated and dried evenly.

[0012] Preferably, casters are installed at all four corners of the bottom of the cabinet. The casters allow the device to be moved flexibly to different locations, and the self-locking structure can fix the device after it is moved into place, enhancing the device's mobility and stability.

[0013] Compared with the prior art, the advantages of this utility model are as follows: 1. This utility model utilizes an upper and lower air chamber inside the cabinet. An air intake fan draws external air into the upper air chamber, and after the heating lamp heats the air, the hot air enters the drying area evenly through the connecting port. At the same time, the exhaust fan in the lower air chamber works in conjunction with the guide plate, with each exhaust fan precisely connected to a guide cavity. This allows for the rapid extraction of moisture generated in the drying area and its discharge to the outside of the device through the exhaust port, forming a highly efficient airflow circulation system. This ensures that the hot air flows continuously within the device, accelerating the evaporation rate of moisture on the surface of the ginkgo leaves, improving drying efficiency, and shortening drying time.

[0014] 2. This utility model uses a pressure net placed inside the tray to fix the position of ginkgo leaves during the drying process, preventing them from piling up, rolling, or floating under the blowing of hot air. This not only ensures that each ginkgo leaf is heated evenly and dried evenly, but also avoids the ginkgo leaves from sticking together or being damaged due to movement, further improving the drying quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 This embodiment provides a ginkgo leaf drying and shaping device, including a cabinet 1. The cabinet 1 has an upper air chamber 2 and a lower air chamber 3 inside. The top of the cabinet 1 has an air inlet 4, which is connected to the upper air chamber 2. The bottom of the cabinet 1 has symmetrically arranged exhaust vents 5, which are connected to the lower air chamber 3. The cabinet 1 has guide chambers 6 on both sides and in the middle. Several guide chambers 6 divide the interior of the cabinet 1 into two drying zones 7. The bottom of each guide chamber 6 is connected to the lower air chamber 3. The two sides of each drying zone 7 are fixedly connected to support rails 8 at equal intervals. The drying zone 7 has trays 9 at equal intervals. The bottom sides of each tray 9 are slidably connected to the corresponding support rails 8. The guide chambers 6 and the top of each tray 9 have exhaust vents 10 at corresponding positions.

[0023] When the ginkgo leaf drying and shaping device is working, firstly, external air enters the upper air chamber 2 from the air inlet 4 at the top of the cabinet 1. Inside the upper air chamber 2, the air can be heated by the heating lamp 12 to become hot air with a certain temperature and drying capacity. Due to the air pressure, the heated hot air will enter the drying zone 7 from the top of the upper air chamber 2 through the connecting port 13. The hot air flows in the drying zone 7 and enters the guide cavity from the exhaust port 10 opened at the corresponding position on the top of the tray 9.

[0024] Hot air passes over the top of tray 9, causing the moisture on the surface of the ginkgo leaves on tray 9 to evaporate. Since there are guide chambers 6 on both sides and in the middle of the cabinet 1, and hot air circulates in both drying zones 7, the temperature and airflow distribution in the entire drying zone 7 can be relatively uniform, thus achieving uniform drying of the ginkgo leaves. As the drying process proceeds, the moisture evaporated from the ginkgo leaves will flow downward with the airflow and enter the lower air chamber 3 through the guide chambers 6. The lower air chamber 3 plays the role of collecting moisture. Finally, the moisture is discharged from the outside of the device through the exhaust vents 5 symmetrically arranged at the bottom of the cabinet 1, keeping the air inside the device relatively dry, which is conducive to the continuous drying process.

[0025] Meanwhile, the sliding connection of tray 9 allows operators to flexibly adjust the position and quantity of tray 9 on support rail 8 according to the degree of dryness, quantity, and characteristics of different batches of ginkgo leaves, in order to meet diverse drying needs. Secondly, the sliding method also facilitates the picking up and putting down of tray 9.

[0026] An air intake fan 11 is fixedly installed inside the upper air chamber 2 directly below the air inlet 4. Heating lamps 12 are fixedly installed on both sides of the air intake fan 11 inside the upper air chamber 2. A connecting port 13 is symmetrically provided at the bottom of the upper air chamber 2. The upper air chamber 2 is connected to the drying zone 7 through the connecting port 13.

[0027] When the ginkgo leaf drying and shaping device is working, the air intake fan 11 is activated. Under the suction of the air intake fan 11, external air quickly enters the upper air chamber 2 from the air intake 4 at the top of the cabinet 1. Compared with relying solely on natural air intake, the air intake fan 11 improves air intake efficiency and can provide sufficient air for the drying process more quickly. As the air enters the upper air chamber 2, it passes through the heating lamps 12 installed on both sides of the air intake fan 11. The heating lamps 12 emit heat to heat the air, raising the air temperature to a range suitable for drying ginkgo leaves. By adjusting the power of the heating lamps 12, the heating temperature of the air can be controlled to meet the needs of different batches of ginkgo leaves or different drying stages.

[0028] The heated air accumulates in the upper air chamber 2. Since the bottom of the upper air chamber 2 is symmetrically provided with connecting ports 13, the hot air enters the drying zone 7 through the connecting ports 13 under the action of air pressure, passes through each tray 6, and the moisture on the surface of the ginkgo leaves on the tray 9 is evaporated by the heat. Then the airflow of moisture enters the guide cavity 6 from the exhaust port 10, enters the lower air chamber 3, and is discharged from the outside of the device from the exhaust port 5.

[0029] The lower air chamber 3 is equipped with a partition 14. Exhaust fans 15 are fixedly installed at equal intervals at the bottom of the partition 14. Two guide plates 16 are fixedly connected between the top of the partition 14 and the top inner wall of the upper air chamber 2. The two guide plates 16 separate the area above the exhaust fans 15, and each exhaust fan 15 is connected to a guide cavity 6.

[0030] The exhaust fan 15 in the lower air chamber 3 starts to operate. Since each exhaust fan 15 is connected to a guide cavity 6 and the two guide plates 16 separate the area above the exhaust fan 15, the exhaust fan 15 can more effectively and quickly extract the moisture from the drying zone 7 in the corresponding guide cavity 6. Under the action of the exhaust fan 15, the moisture is accelerated to be discharged from the exhaust port 5 at the bottom of the lower air chamber 3 to the outside of the device, effectively preventing the accumulation of moisture in the lower air chamber 3 and ensuring the relative dryness of the air inside the device. At the same time, the operation of the exhaust fan 15 also helps to form the airflow circulation inside the device. It creates a certain air pressure difference between the upper air chamber 2 and the lower air chamber 3, which promotes the smoother circulation of hot air between the upper air chamber 2, the drying zone 7 and the lower air chamber 3, further improving the drying efficiency and drying uniformity of the ginkgo leaves.

[0031] Cabinet 1 is symmetrically connected to cabinet doors 17 on both sides. A sealing strip 18 is provided on one edge of the cabinet door 17. When the cabinet door 17 is rotated around the rotating connection with the cabinet 1, the cabinet door 17 is closed. When the cabinet door 17 is closed, the sealing strip 18 will fit tightly against the corresponding position of the cabinet 1, forming a good sealing effect.

[0032] The bottom of the tray 9 is symmetrically provided with hand pull grooves 19. By using the force points provided by the hand pull grooves 19, the tray 9 can be held conveniently and effortlessly. Then, by applying appropriate pulling or pushing force, the tray 9 can be easily slid along the support rail 8 to adjust the position of the tray 9, or the tray 9 can be completely pulled out from the cabinet 1 for loading and unloading of ginkgo leaves.

[0033] A pressure mesh 20 is placed inside the tray 9. First, the ginkgo leaves to be dried are evenly spread inside the tray 9. Then, the pressure mesh 20, whose size is adapted to the internal size of the tray 9, is placed on top of the ginkgo leaves. Due to the mesh structure of the pressure mesh 20 and its adaptation design with the tray 9, the pressure mesh 20 can stably cover the ginkgo leaves, apply a certain pressure to the ginkgo leaves, and fix them inside the tray 9. The presence of the pressure mesh 20 can effectively prevent the ginkgo leaves from piling up, rolling, or floating under the blowing of hot air. On the one hand, it avoids the problem of uneven heating caused by the piling up of ginkgo leaves, resulting in some ginkgo leaves being over-dried while others are not fully dried. It ensures that each ginkgo leaf can be evenly blown by hot air, improving the drying quality. On the other hand, it prevents the ginkgo leaves from floating to other areas, ensuring that the drying process is carried out in an orderly manner, and also reduces the interference that the floating of ginkgo leaves may cause to the internal structure of the device.

[0034] All four corners of the bottom of the cabinet 1 are equipped with casters 21. When the device needs to be moved, the operator does not need to exert much effort to move it. He only needs to push or pull the cabinet 1 gently. The casters 21 can flexibly change the direction of rotation, so that the device can be moved easily in all directions.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
