Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a double-sided drying device for Chinese herbal medicine slices and a drying method thereof. Background Art

[0002] Traditional Chinese medicine refers to substances used to prevent, treat, diagnose diseases and have rehabilitation and health-care effects under the guidance of traditional Chinese medicine theory. Traditional Chinese medicine mainly comes from natural medicines and their processed products, including botanical medicines, animal medicines, mineral medicines and some chemical and biological products. Botanical medicines naturally contain moisture. In order to increase the storage time of medicinal materials and maintain the efficacy, the medicinal materials generally need to be dried before storage to remove excess moisture.

[0003] For drying thin slices of Chinese medicinal materials, the slices are placed on a drying tray. In the process, in order to ensure that the Chinese medicinal materials can be fully dried, they need to be turned over. Existing drying equipment usually uses manual turning or uses equipment vibration to assist in turning. The above turning operation is relatively cumbersome. Generally, only one turning is performed in a single drying process. Since some medicinal materials naturally contain sugars, resins or sticky substances, these ingredients will become more viscous when heated, making them easy to adhere to the tray. Therefore, after completing single-sided drying, the medicinal material slices are often difficult to turn over easily due to adhesion. Forced turning will also cause damage to the medicinal materials and affect the processing quality. Summary of the invention

[0004] The purpose of the present invention is to solve the problem of sticking of Chinese medicinal materials during drying in the prior art, making it difficult to turn the medicinal materials over, resulting in uneven drying, and to propose a double-sided drying Chinese medicinal material slice efficient drying equipment and a drying method.

[0009] Preferably, the height interval between the tray and the mounting plate is 5-10 mm, which is used for drying thin slices of Chinese medicinal materials with a thickness of 1-3 mm.

[0010] Preferably, a plurality of partition plates are equidistantly installed on the upper surface of the tray, and the partition plates are installed along the depth direction of the box body so that the partition plates are perpendicular to the flow direction of the airflow.

[0011] Preferably, a plurality of guide plates are arranged above the mounting plate, the guide plates are rotatably connected to the inner box body via a limiting structure, and the guide plates are parallel to the partition plates.

[0012] Preferably, the limiting structure comprises a mounting ring fixedly mounted on the side wall of the inner box body, a rotating shaft rotatably connected to the mounting ring is mounted at the bottom end of the guide plate, a fan-shaped notch is provided on the rotating shaft, and a limiting block located in the fan-shaped notch is fixedly mounted on the inner wall of the mounting ring.

[0013] Preferably, the rotation angle range of the guide plate is 45°-135°.

[0014] A drying method of a double-sided drying Chinese herbal medicine slice high-efficiency drying device comprises the following steps: Place the slices of Chinese medicinal materials. Cut the washed Chinese medicinal materials into thin slices of 1-3mm thickness. After pulling out the tray, lay the cut surface of the Chinese medicinal materials on the tray in a single layer. After the tray is fully laid, push the tray back into the inner box, and complete the placement of the medicinal materials of all supporting components in sequence. Start the two-way fans, start one of the two-way fans for blowing, start the other two-way fan for exhausting, the blowing two-way fan blows air into the air chambers at odd-numbered positions through the air flow duct, and the exhausting two-way fan exhausts air into the air chambers at even-numbered positions through the air flow duct, the air chambers at odd-numbered positions blow air into the trays at adjacent positions, and the air chambers at even-numbered positions exhaust air into the trays at adjacent positions, the Chinese medicinal material slices on the tray between the exhaust air chamber at the top and the blowing air chamber at the bottom are subjected to suction force at the top and blowing force at the bottom, the Chinese medicinal material slices float up and fit on the lower surface of the mounting plate, the lower surface of the Chinese medicinal material slices is exposed, and drying is completed, the Chinese medicinal material slices on the tray between the blowing air chamber at the top and the exhaust air chamber at the bottom are subjected to blowing force at the top and suction force at the bottom, the Chinese medicinal material slices fit on the upper surface of the tray, the upper surface of the Chinese medicinal material slices is exposed, and drying is completed; Alternate double-sided drying, after drying for 5-10 minutes, control the two bidirectional fans to switch states, the bidirectional fan for initial exhaust starts blowing, and the bidirectional fan for initial blowing starts exhausting, the air pressure state of all air chambers changes, the position of Chinese medicinal material slices also changes, the medicinal materials on the upper surface initially dried are dried on the lower surface, and the medicinal materials on the lower surface initially dried are dried on the upper surface.

[0015] Compared with the prior art, the present invention has the following advantages: 1. By setting up two bidirectional fans and alternately controlling their blowing and exhausting states, a pressure difference is formed between the two adjacent air chambers, thereby realizing double-sided alternating drying of Chinese medicinal material slices. Compared with the single-sided drying of traditional drying equipment, it not only improves the drying efficiency, but also ensures that both sides of the Chinese medicinal material slices can be dried evenly and fully.

[0016] 2. During the drying process, the slices of Chinese medicinal materials will be affected by the suction force of the upper air chamber and the blowing force of the lower air chamber, and will automatically float up and fit the bottom surface of the installation plate, so that the lower surface of the medicinal materials is completely exposed, or the slices of Chinese medicinal materials will be affected by the blowing force of the upper air chamber and the suction force of the lower air chamber and fit on the tray, so that the upper surface of the medicinal materials is completely exposed, thereby realizing double-sided drying. There is no need to turn the medicinal materials over to achieve the drying operation of the medicinal materials. Through the alternating blowing and exhausting of the two-way fan, the single-sided drying time of the cut surface of the Chinese medicinal materials will not be too long, which effectively avoids the bonding problem of the Chinese medicinal materials slices caused by long-term drying. Since there is no need for manual turning, the tedious steps of manual turning are reduced, thereby reducing labor costs.

[0017] 3. In the existing drying technology, in order to achieve double-sided drying of medicinal materials, it is usually necessary to manually or mechanically turn or vibrate the medicinal materials to a large extent. This operation method can easily cause damage, deformation or surface scratches of the medicinal materials, thereby affecting the quality and market value of the medicinal materials. The present invention achieves double-sided drying by slightly floating the Chinese medicinal materials during the drying process. There is no need for large-scale turning or vibration, which effectively reduces the risk of damage to the medicinal materials. It not only avoids the destruction of the medicinal material structure, but also protects the integrity and stability of the medicinal ingredients, thereby improving the medicinal value of the medicinal materials.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-6A high-efficiency drying device for Chinese medicinal material slices with double-sided drying includes a box body 1, which includes a drying area 11 located at the top and a control area 12 located below the drying area 11, wherein the drying area 11 has a box door 13, and the box door 13 is connected to the box body 1 through a hinge, the box door 13 can be opened, and a lock is provided between the box door 13 and the box body 1. When the drying equipment is working, the box door 13 is closed and locked by the lock.

[0022] An inner box 14 is provided in the drying area 11, and the inner box 14 is fixed in the box 1. A partial gap can be reserved between the inner box 14 and the box 1 for filling with insulation materials. A plurality of groups of supporting components 2 for holding slices of Chinese medicinal materials are provided in the inner box 14. The plurality of groups of supporting components 2 are arranged horizontally and equidistantly distributed in the vertical direction. An air chamber 3 for hot air flow to pass through is formed between two adjacent supporting components 2. The longitudinal projection range of the air chamber 3 covers the supporting components 2. The air flow can flow from one of the air chambers 3 to the adjacent air chamber 3 through the supporting components 2. During the flow of the air flow, moisture on the slices of Chinese medicinal materials in the supporting components 2 is taken away, thereby realizing medicinal material drying.

[0023] Reference Figure 1-6 The supporting assembly 2 includes a mounting plate 21 and a tray 22. A plurality of air holes 23 are provided on the mounting plate 21 and the tray 22. The diameter of the air holes 23 is smaller than the diameter of the sliced ​​Chinese medicinal materials, so as to ensure that the mounting plate 21 and the tray 22 can support the sliced ​​Chinese medicinal materials. The mounting plate 21 is fixedly installed in the inner box 14. The tray 22 and the inner box 14 are sealed and slidably matched through a sliding structure. When placing the medicinal materials, the tray 22 can be pulled outward with the door 13 opened. The medicinal materials are placed in a single layer on the tray 22 to ensure that the outer surface of the medicinal materials is fully exposed, which is conducive to uniform drying. After the placement is completed, the tray 22 is pushed inward. Under the action of the sliding structure, the tray 22 can slide stably and horizontally, and after the tray 22 completely enters the inner box 14, the sliding connection between the tray 22 and the inner box 14 is kept sealed.

[0024] Reference Figure 1-6 The sliding structure includes a slide rail 211 fixedly arranged on the inner wall of the inner box 14 and the bottom surface of the mounting plate 21. Card strips 221 adapted to the slide rail 211 are installed on both sides of the tray 22. The card strip 221 has a card slot close to the side of the slide rail 211. The slide rail 211 is clamped in the card slot and can slide relative to the card strip 221 in the length direction. The cooperation between the slide rail 211 and the card strip 221 ensures the stability of the tray 22 during the sliding process, ensures the accuracy of the tray 22 pulling process, and avoids shaking or tilting.

[0025] A limiting slot is provided on the slide rail 211 along the length direction, and a limiting column penetrating the limiting slot is fixedly installed at one end of the slot close to the interior of the box body 1. The limiting column cooperates with the limiting slot to limit the pulling position of the tray 22 to prevent the tray 22 from being directly pulled out due to misoperation and causing the medicinal materials to scatter. When the tray 22 is completely located in the box body 1, the limiting column is located at the innermost end of the limiting slot, and when the tray 22 is pulled out to the limit position, the limiting column is located at the outermost end of the limiting slot.

[0026] Two two-way fans 4 are arranged in the control area 12. The two-way fans 4 can specifically adopt axial flow fans, which output airflow axially through the rotation of blades. They can be driven by a servo motor. When the servo motor is controlled to rotate in the opposite direction, the airflow direction is changed. One end of the two-way fan 4 is connected to an airflow duct 5 extending to the drying area 11. The two-way fan 4 transports airflow to the drying area 11 through the airflow duct 5. A heater can be added at the connection between the airflow duct 5 and the two-way fan 4 to increase the airflow temperature and realize hot air drying. The heater is a prior art and its installation position is not unique, which is not shown in the figure. The two airflow ducts 5 are respectively located on both sides of the drying area 11, one of which is connected to the air chamber 3 at the odd position, and the other is connected to the air chamber 3 at the even position.

[0027] When one of the two-way fans 4 blows air, the other two-way fan 4 draws air, so that a pressure difference is formed between the two adjacent air chambers 3, thereby realizing alternating double-sided drying of the Chinese medicinal material slices. Compared with the single-sided drying of traditional drying equipment, it not only improves the drying efficiency, but also ensures that both sides of the Chinese medicinal material slices can be dried evenly and fully.

[0028] Specifically, refer to Figure 2 and 7In order to better understand the working state of the present invention, take the air chamber 3a, the air chamber 3b, the air chamber 3c supporting assembly 2a and the supporting assembly 2b as an example, wherein the air chamber 3a and the air chamber 3c are located on odd-numbered floors, the two-way fan 4a is connected to the air chamber 3a and the air chamber 3c through the air flow duct 5a, the air chamber 3b is located on the even-numbered floors, the two-way fan 4b is connected to the air chamber 3b through the air flow duct 5b, and the supporting assembly 2a is located between the air chamber 3a and the air chamber 3b, and the supporting assembly 2b is located between the air chamber 3a and the air chamber 3b. Between the air chamber 3b and the air chamber 3c, the sliced ​​surface of the Chinese medicinal materials is laid flat on the tray 22a and the tray 22b in a single layer. The two-way fan 4a is started to blow air, and the two-way fan 4b is started to exhaust air. The two-way fan 4a blows air into the air chamber 3a and the air chamber 3c through the air flow duct 5a, and the two-way fan 4b exhausts air into the air chamber 3b through the air flow duct 5b. The sliced ​​Chinese medicinal materials on the tray 22a are subjected to the blowing force of the upper air chamber 3a and the suction force of the air chamber 3b, and the sliced ​​Chinese medicinal materials will be attached to the tray 22a. The upper surface of the Chinese medicinal material slices is exposed on the upper surface of the tray 22a, and the drying is completed under the action of the airflow. The Chinese medicinal material slices on the tray 22b are subjected to the suction force of the upper air chamber 3b and the blowing force of the air chamber 3c, and will float up and fit on the lower surface of the mounting plate 21b, and the lower surface of the Chinese medicinal material slices is exposed, and the drying is completed under the action of the airflow. By switching the output directions of the two-way fan 4a and the two-way fan 4b, the two-way fan 4a exhausts air, and the two-way fan 4b is started to blow air. The Chinese medicinal material slices on the tray 22a are subjected to the suction force of the upper air chamber 3a and the blowing force of the air chamber 3b, and the Chinese medicinal material slices will fit on the lower surface of the mounting plate 21a, and the lower surface of the Chinese medicinal material slices is exposed, and the drying is completed under the action of the airflow. The Chinese medicinal material slices on the tray 22b are subjected to the blowing force of the upper air chamber 3b and the suction force of the air chamber 3c, and will fit on the upper surface of the tray 22b, and the upper surface of the Chinese medicinal material slices is exposed, and the drying is completed under the action of the airflow.

[0029] During the drying process, the sliced ​​Chinese medicinal materials will be affected by the suction force of the upper air chamber 3 and the blowing force of the lower air chamber 3, and will automatically float up and fit the bottom surface of the mounting plate 21, so that the lower surface of the medicinal materials is completely exposed; or the sliced ​​Chinese medicinal materials will be affected by the blowing force of the upper air chamber 3 and the suction force of the lower air chamber 3 and fit on the tray 22, so that the upper surface of the medicinal materials is completely exposed, thereby realizing double-sided drying, and the medicinal materials do not need to be turned over to achieve the drying operation.

[0030] The two bidirectional fans 4 switch their working states intermittently, so that the air pressure in the air chamber 3 changes alternately. Through the alternating blowing and exhausting of the bidirectional fans 4, the single-sided drying time of the cut surface of the Chinese medicinal materials will not be too long, effectively avoiding the problem of sticking of the Chinese medicinal materials slices caused by long-term drying.

[0031] The height interval between the tray 22 and the mounting plate 21 is 5-10mm, preferably 5mm, which is used to dry thin slices of Chinese medicinal materials with a thickness of 1-3mm, preferably 3mm. The 3mm Chinese medicinal material slices have a floating range of 2mm in the height interval of 5mm, which is sufficient for air flow, and the position of the Chinese medicinal material slices is close to the mounting plate 21, which is conducive to generating sufficient suction to float the Chinese medicinal material slices when exhausting air.

[0032] A plurality of partition plates 222 are equidistantly installed on the upper surface of the tray 22. The partition plates 222 are installed along the depth direction of the box body 1 so that the partition plates 222 are perpendicular to the flow direction of the airflow, ensuring that under the action of the airflow, the slices of Chinese medicinal materials will not be stacked in a horizontal position under the action of the airflow, thereby avoiding affecting the drying of the medicinal materials.

[0033] Reference Figure 1-7 , a plurality of guide plates 212 are arranged above the mounting plate 21, and the guide plates 212 are rotatably connected to the inner box body 14 through a limiting structure, and the guide plates 212 are parallel to the partition plates 222, and the airflow in the air chamber 3 can be guided by the guide plates 212 to avoid local concentration of the airflow in the air chamber 3. The airflow duct 5 is located on both sides of the drying area 11, and the airflow will flow from the high-pressure air chamber 3 of blowing to the adjacent low-pressure air chamber 3 of exhausting through the supporting assembly 2, and the guide plates 212 are pushed to rotate in the forward direction of the airflow during the flow process. In the exhausting air chamber 3, the guide plates 212 are deflected to the side close to the airflow duct 5, and the angle less than 90° formed by the guide plates 212 is conducive to the passage of air. In the blowing air chamber 3, the guide plates 212 are deflected to the side away from the airflow duct 5, and the airflow is blown obliquely upward to the upper tray 22 through the guide plates 212, providing an upward thrust to the slices of Chinese medicinal materials in the tray 22, so as to facilitate the floating of the slices of Chinese medicinal materials.

[0034] Reference Figure 8-9 The limiting structure includes a mounting ring 141 fixedly mounted on the side wall of the inner box body 14, a rotating shaft 213 rotatably connected to the mounting ring 141 is mounted at the bottom end of the guide plate 212, a fan-shaped notch 214 is opened on the rotating shaft 213, and a limiting block 142 located in the fan-shaped notch 214 is fixedly mounted on the inner wall of the mounting ring 141. The rotation angle range of the guide plate 212 is 45°-135°. When the guide plate 212 rotates, the rotating shaft 213 rotates synchronously, and when it rotates to the extreme positions on both sides, the limiting block 142 abuts against the side walls of the fan-shaped notch 214 to achieve limiting.

[0035] A drying method of a double-sided drying Chinese herbal medicine slice high-efficiency drying device comprises the following steps: Place the slices of Chinese medicinal materials. Cut the washed Chinese medicinal materials into thin slices of 1-3 mm thickness. After the tray 22 is pulled out, lay the cut surface of the Chinese medicinal materials on the tray 22 in a single layer. After the tray 22 is fully laid, push the tray 22 back into the inner box 14, and complete the placement of the medicinal materials of all the supporting components 2 in sequence. Start the two-way fan 4, start one of the two-way fans 4 to blow air, start the other two-way fan 4 to exhaust air, the blowing two-way fan 4 blows air into the air chamber 3 at the odd-numbered position through the air flow duct 5, and the exhaust two-way fan 4 exhausts air to the air chamber 3 at the even-numbered position through the air flow duct 5, the air chamber 3 at the odd-numbered position blows air to the tray 22 at the adjacent position, and the air chamber 3 at the even-numbered position exhausts air to the tray 22 at the adjacent position, and the Chinese medicinal material slices on the tray 22 between the exhaust air chamber 3 at the top and the blowing air chamber 3 at the bottom are subjected to suction force at the top and blowing force at the bottom, and the Chinese medicinal material slices will float up and fit on the lower surface of the mounting plate 21, and the lower surface of the Chinese medicinal material slices is exposed, and the drying is completed, and the Chinese medicinal material slices on the tray 22 between the blowing air chamber 3 at the top and the exhaust air chamber 3 at the bottom are subjected to blowing force at the top and suction force at the bottom, and the Chinese medicinal material slices will fit on the upper surface of the tray 22, and the upper surface of the Chinese medicinal material slices is exposed, and the drying is completed; Alternate double-sided drying, after drying for 5-10 minutes, control the two bidirectional fans 4 to switch states, the bidirectional fan 4 for initial exhaustion blows air, and the bidirectional fan 4 for initial blowing exhausts air, the air pressure state of some air chambers 3 changes, and the position of the Chinese medicinal material slices also changes, the medicinal materials on the upper surface initially dried are dried on the lower surface, and the medicinal materials on the lower surface initially dried are dried on the upper surface.

The Chinese medicinal material slices on the tray (22) between the air chamber (3) and the blowing chamber (3) below receive suction force at the top and blowing force at the bottom, so that the Chinese medicinal material slices float up and fit on the lower surface of the mounting plate 21, and the lower surface of the Chinese medicinal material slices is exposed, and the drying is completed. The Chinese medicinal material slices on the tray (22) between the blowing chamber (3) at the top and the exhaust chamber (3) at the bottom receive blowing force at the top and suction force at the bottom, so that the Chinese medicinal material slices fit on the upper surface of the tray 22, and the upper surface of the Chinese medicinal material slices is exposed, and the drying is completed. Alternate double-sided drying. After drying for 5-10 minutes, the two bidirectional fans (4) are controlled to switch states. The bidirectional fans (4) for initial exhaustion are used to blow air, and the bidirectional fans (4) for initial blowing are used to exhaust air. The air pressure states of all air chambers (3) are changed, and the positions of the sliced ​​Chinese medicinal materials are also changed. The medicinal materials on the upper surface that were initially dried are dried on the lower surface, and the medicinal materials on the lower surface that were initially dried are dried on the upper surface.
