[0038] A Schisandra chinensis drying device, for example Figures 1 to 5 As shown:

[0039] It includes a drying barrel 1, a discharge pipe 6 fixedly installed on the right side of the drying barrel 1, and a bearing structure installed in the drying barrel 1.

[0040] A feed inlet is coaxially formed at the top of the drying barrel 1. A discharge port is formed on the right side of the drying barrel 1 and communicates with a discharge pipe 6. The end of the discharge pipe 6 is tilted downward, and an air inlet pipe 7 is fixedly mounted above the discharge pipe 6. The discharge pipe 6 has an air inlet opening that communicates with the air inlet pipe 7. Furthermore, a blocking block can be inserted into the end of the discharge pipe 6.

[0041] The supporting structure includes a bottom tray 2 mounted within the drying drum 1 and a slag tray 13 mounted within the drying drum 1. The slag tray 13 is mounted below the bottom tray 2 and tilted toward the discharge port. In this embodiment, the tilt of the slag tray 13 is aligned with the tilt of the discharge pipe 6. The bottom tray 2 is coaxial with the drying drum 1 and has several drainage holes smaller than the size of the Schisandra chinensis.

[0042] like Figure 1 As shown, a top baffle 4 is mounted above the drying barrel 1, along with a lifting assembly to control the raising and lowering of the top baffle 4. A soft pad is also fixed to the inside of the top baffle 4. Furthermore, the pad mounted at the bottom of the top baffle 4 has several leakage holes smaller than the size of the Schisandra chinensis.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the bottom tray 2 can rotate in the drying barrel 1. A driving structure for driving the bottom tray 2 to rotate is installed in the drying barrel 1. Specifically, an active sleeve 12 is coaxially fixedly installed on the bottom of the bottom tray 2, and the driving structure includes a sleeve shaft 11 coaxially installed and rotatable at the bottom of the drying barrel 1, a driving motor installed at the bottom of the drying barrel 1, and a gear transmission mechanism installed between the output shaft of the driving motor and the bottom end of the sleeve shaft 11. A through hole is provided on the slag discharge plate 13 for the sleeve shaft 11 to pass through. After passing through the through hole, the sleeve shaft 11 extends into the active sleeve ring 12. Several vertical slide grooves are circumferentially provided in the active sleeve ring 12. The sleeve shaft 11 extends into the active sleeve ring 12 and is circumferentially fixed with several vertical sliders that respectively engage with the vertical slide grooves. The vertical sliders can slide vertically in the vertical slide grooves.

[0044] In this embodiment, the bottom tray 2 and the slag tray 13 can also slide vertically synchronously in the drying barrel 1. Specifically, a driven collar coaxial with the active collar 12 is fixed to the slag tray 13. The active collar 12 has a closed T-shaped ring groove formed inward at the bottom end, and a closed T-shaped ring platform is formed on the top end of the driven collar. The T-shaped ring platform engages into the T-shaped ring groove and can rotate around the axis inside. Two vertical sliders are formed on both sides of the slag tray 13, and two vertical slide grooves are formed on the inner wall of the drying barrel 1 for the two vertical sliders to slide inside. A spring is also installed between the bottom of the slag tray 13 and the inner bottom surface of the drying barrel 1, and the bottom tray 2 and the slag trough are lifted upward by the spring.

[0045] An inner extension platform is formed inwardly on the top of the drying barrel 1, and a wave-shaped meshing ring platform 14 is formed on the inner side of the inner extension platform. Two protrusions 10 that can fit the meshing ring platform 14 are fixedly installed at equal distances on the top of the annular baffle 9.

[0046] like Figure 1 and Figure 2As shown, in this embodiment, the bottom tray 2 also has a driven ring plate extending outward, and an active ring plate is installed in the drying barrel 1. The active ring plate can slide vertically in the drying barrel 1, and the bottom surface of the active ring plate can fit with the top surface of the driven ring table. A control structure 1 for controlling the height of the active ring plate is also installed in the drying barrel 1. Specifically, limiting grooves are provided on both sides of the drying barrel 1, and a connecting ring plate extends downward from the outer wall of the active ring plate. The outer wall of the connecting ring plate is formed with two limiting plates 8 that extend out of the limiting grooves and can move vertically. The control structure 1 includes support plates respectively fixed to the two sides of the outside of the drying barrel 1 and cylinders 1 respectively fixed to the support plates. The output ends of the cylinders 1 are respectively fixedly connected to the limiting plates 8 on the same side.

[0047] like Figure 3 、 Figure 4 and Figure 5 As shown, the lifting assembly includes a receiving plate, a secondary transmission shaft 3, and a second control structure. Connecting rods are mounted on the sidewalls of the drying drum 1 to support the receiving plate, positioning it above the drying drum 1. The receiving plate has a shaft hole for mounting the secondary transmission shaft 3. The second control structure is mounted above the receiving plate to control the height of the secondary transmission shaft 3. A top baffle 4 is connected to the secondary transmission shaft 3.

[0048] Specifically, the control structure 2 includes a cylinder 2 fixed on a receiving plate and a connecting plate fixed on the end of the output shaft of the cylinder 2. The connecting plate is provided with a hole for the auxiliary transmission shaft 3 to pass through, and an annular groove is provided on the inside of the hole. The outer wall of the auxiliary transmission shaft 3 located in the hole is formed with a circle of closed annular platforms, which engage in the annular groove and can rotate around the axis.

[0049] In this embodiment, the sleeve 11 is coaxially connected to a core shaft 15. A positioning plate is fixedly mounted at the bottom end of the drying barrel 1 to fix the angle of the core shaft 15. A vertical slot 3 is defined at the bottom end of the core shaft 15. The positioning plate has an axial hole for the core shaft 15 to pass through. A vertical slider 3 is formed within the axial hole and slides within the vertical slot 3. The top end of the core shaft 15 passes through the top tray and is rotatable relative to the bottom tray 2. A gear transmission box 5 is also fixedly mounted on the top surface of the bottom tray 2. Within this gear transmission box 5 is a gear transmission mechanism 2 for reverse transmission.

[0050] like Figure 4 As shown, the top end of the mandrel 15 extends into the gear transmission case 5 and serves as the input of the second gear transmission mechanism. The gear transmission case 5 also houses a main transmission shaft 16, which serves as the output of the second gear transmission mechanism. The second gear transmission mechanism comprises a rotating shaft 1, which is rotatably mounted within the gear transmission case 5, a driving gear fixedly mounted at the end of the mandrel 15, transmission gears 1 and 2 mounted on the rotating shaft 1, and a driven gear mounted on the main transmission shaft 16. Transmission gear 1 meshes with the driving gear, and transmission gear 2 meshes with the driven gear, driving the main transmission shaft 16 to rotate in the opposite direction via the mandrel 15.

[0051] The auxiliary transmission shaft 3 can extend into the gear transmission box 5 and be coaxially connected to the main transmission shaft 16. Specifically, a synchronous connection member is installed between the auxiliary transmission shaft 3 and the main transmission shaft 16. Figure 5 As shown, the synchronous connecting member includes a plurality of reverse triangular protrusions 10 fixed on the top surface of the main transmission shaft 16 and connected end to end in sequence to form a ring, and a plurality of forward triangular protrusions 10 fixed on the bottom surface of the auxiliary transmission shaft 3 and connected end to end in sequence to form a ring. The reverse triangular protrusions 10 can be respectively engaged with the forward triangular protrusions 10, and in this embodiment, the reverse triangular protrusions 10 and the forward triangular protrusions 10 are both right-angled triangular protrusions 10.

[0052] Furthermore, a hole is formed at the axis of the top baffle 4, and a sleeve is fixed to the top surface of the top baffle 4. The sleeve covers the size, and a connecting sleeve is installed on the top of the sleeve. The secondary transmission shaft 3 passes through the connecting sleeve and the sleeve coaxially. Bolts are screwed into the connecting sleeve to tighten against the outer wall of the secondary transmission shaft 3, thereby fixing the relative position of the connecting sleeve, the sleeve, the top baffle 4 and the secondary transmission shaft 3.

[0053] In this embodiment, in order to ensure that the Schisandra chinensis is evenly spread on the bottom tray 2 and fully covered by the top baffle 4, a cylindrical barrel is provided outside the gear transmission box 5, and the size of the cylindrical barrel is equal to that of the inner cavity of the sleeve.

[0054] The present invention further provides a Schisandra chinensis drying method based on the above-mentioned Schisandra chinensis drying device, comprising the following steps:

[0055] Step A1: Lower the height of the output end of cylinder 1, and drive the active ring plate downward through the limit plate 8, thereby driving the bottom tray 2 and the slag tray 13 to move downward synchronously until the slag tray 13 is lower than the discharge port. At this time, the protrusion 10 installed on the annular baffle 9 of the bottom tray 2 can still fit with a part of the meshing ring platform 14;

[0056] Step A2: Figure 6 As shown, the washed Schisandra chinensis raw material with stems is placed into the bottom tray 2, the height of the output end of the cylinder 2 is lowered, and the auxiliary transmission shaft 3 and the top baffle 4 are controlled to descend until the bottom baffle enters the inner side of the annular baffle 9, but the auxiliary transmission shaft 3 does not stop when it is connected to the main transmission shaft 16;

[0057] Step A3: insert a block into the end of the discharge pipe 6 and start the drive motor until the water on the Schisandra chinensis raw material is dried;

[0058] The output shaft of the driving motor rotates through the gear transmission mechanism to drive the sleeve shaft 11 to rotate, and the sleeve shaft 11 drives the active sleeve ring 12 and the bottom tray 2 to rotate synchronously, driving the Schisandra chinensis raw material on the bottom tray 2 to rotate to shake off the moisture, and the moisture falls from the leakage hole on the bottom tray 2 to the slag discharge tray 13 below;

[0059] Step A4: reducing the rotation speed of the output shaft of the driving motor and introducing high-temperature airflow from the air inlet pipe 7;

[0060] The high-temperature airflow is used to dry the Schisandra chinensis raw material on the bottom tray 2, and the separated water is retained on the slag tray 13. After the high-temperature airflow is introduced, the water will be evaporated to form high-temperature steam that passes through the Schisandra chinensis raw material, which can better facilitate the subsequent processing of Schisandra chinensis and achieve the desired medicinal effect and quality of Schisandra chinensis.

[0061] Step A5: After the water on the slag tray 13 has evaporated, the height of the output end of cylinder 1 and the height of the output end of cylinder 2 are raised to connect the slag tray 13 to the discharge port, and the protrusion 10 is brought close to the engagement ring 14. The top baffle 4 is lifted to ensure that the auxiliary transmission shaft 3 is not connected to the main transmission shaft 16.

[0062] During the drying process, the protrusions 10 are attached to the meshing ring 14 and move forward, causing the bottom tray 2 to shake periodically, which can disperse and shake the Schisandra chinensis raw materials and shorten the drying time.

[0063] Step A6: Figure 7 As shown, after drying is completed, remove the block, lower the height of the output end of cylinder two, lower the top baffle 4 and the auxiliary transmission shaft 3, make the cushion fit the Schisandra chinensis, connect the auxiliary transmission shaft 3 with the main transmission shaft 16, until the stem removal operation is completed, raise the output end of cylinder two, stop the output shaft of the drive motor, and take out the Schisandra chinensis on the bottom tray 2.

[0064] After the soft cushion is fitted with the Schisandra chinensis, the secondary transmission shaft 3 is connected to the main transmission shaft 16, and synchronous transmission is performed through the synchronous connecting piece. At this time, when the bottom tray 2 is driven clockwise by the sleeve shaft 11, the core shaft 15 drives the main transmission shaft 16 counterclockwise through the second gear transmission mechanism, driving the top baffle 4 to rotate counterclockwise, so that the rotation directions of the bottom tray 2 and the top baffle 4 are opposite. In this way, during the rotation process, the soft cushion presses down on the Schisandra chinensis, causing it to roll on the bottom tray 2, and the dried stems are removed during the rolling process. The stems fall through the leakage hole into the slag tray 13 below.

[0065] In this process, the bottom tray 2 and the slag tray 13 can also be shaken slowly. Because the main transmission shaft 16 and the auxiliary transmission shaft 3 are driven by the engagement of the reverse triangular protrusion 10 and the forward triangular protrusion 10, the forward triangular protrusion 10 of the auxiliary transmission shaft 3 will automatically correct the connection position due to the fit of the inclined surface of the triangular protrusion 10. Therefore, when shaking and separating to the next connection, they can still engage, thereby increasing the completeness of stem removal.

[0066] The present invention can not only directly dehydrate and then dry the Schisandra chinensis raw material with water droplets just after cleaning, but also form high-temperature water vapor through the desorbed water during the drying process. The water will be evaporated to form high-temperature steam that passes through the Schisandra chinensis raw material, which can better facilitate the subsequent processing of Schisandra chinensis and make Schisandra chinensis achieve the required medicinal effect and quality. Moreover, during the dehydration and drying process, the bottom tray 2 can also drive the Schisandra chinensis raw material to shake, realize the "turning over" of the Schisandra chinensis raw material, and can disperse and shake the Schisandra chinensis raw material, shortening the time required for drying. At the same time, the present invention can also achieve the destemming of the dried Schisandra chinensis. When the secondary transmission shaft 3 is engaged with the main transmission shaft 16, the soft pad rotates in the opposite direction to the bottom tray 2, and the Schisandra chinensis is pressed down by the soft pad to roll on the bottom tray 2, and the dried stems are removed during the rolling process, and the stems can fall into the slag tray 13 below through the leakage hole.

[0067] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
