The drum is driven to rotate by the rotating motor. The central shaft is arranged in the drum, and its driving end extends to the outer side of the drum. The central shaft is driven to rotate by the speed regulating motor. The central shaft has a channel. By inputting water vapor into the internal channel of the central shaft and sending it into the drum, the material is heated evenly. It should be noted that after the medicinal material is heated to a predetermined temperature, since the temperature sensor is mostly arranged in the central area of the drum, and since the peripheral material is in direct contact with the metal wall of the drum, the heat is quickly transferred to the external environment through heat conduction; and the heat in the central area needs to be conducted step by step through the peripheral material layer, so that the heat dissipation speed of the material located on the inside is slower than the heat dissipation speed of the material located on the outside, and then the value displayed by the temperature sensor is difficult to accurately reflect the temperature of the peripheral material, which is not conducive to the temperature control of the material.

[0023] A medicinal herb stir-frying machine with schematic material dynamic constant temperature Reference Figures 1 to 4 , a medicinal herb stir-frying machine with material dynamic constant temperature according to a preferred embodiment of the present invention, includes a base body 10, a rotary drum 20, a heating device 30, a central shaft 201, and two temperature sensors (not shown in the figure).

[0024] Specifically, the base body 10 has a heating cavity 101, and both the bottom and the top of the heating cavity 101 have flow holes, so that external air can flow into the heating cavity 101 from the flow holes at the bottom of the heating cavity 101 and discharge from the flow holes at the top of the heating cavity 101.

[0025] In addition, the rotary drum 20 is rotatably installed in the heating cavity 101. Specifically, the medicinal herb stir-frying machine with material dynamic constant temperature further includes a first rotary motor and two supporting rollers rotatably installed on the base body 10. The rotating shaft of the first rotary motor is power-connected to the central shaft 201 in a gear transmission manner, that is, the rotating shaft of the first rotary motor has a first gear, the outer wall of the central shaft 201 has a second gear, the first gear meshes with the second gear, the central shaft 201 is rotatably installed on the base body 10, the central shaft 201 is fixedly connected to the rotary drum 20, and the two supporting rollers are located at the other end of the rotary drum 20 and support the rotary drum 20.

[0026] It should be noted that, in the process of heating the medicinal materials, since the heating device 30 is fixed to the bottom of the rotating drum 20, the medicinal materials placed in the rotating drum 20 can be evenly heated by rotating the rotating drum 20.

[0027] In addition, the rotating drum 20 has a medicine frying chamber 202, and the end of the rotating drum 20 away from the first rotating motor has an opening and closing door. Before frying the medicine, the operator opens the opening and closing door and puts the medicinal materials into the rotating drum 20 and closes the opening and closing door.

[0028] In addition, the heating device 30 is located at the bottom of the drum 20. It should be noted that the heating device 30 is heated by open flame to ensure that the medicinal materials can be heated to a predetermined temperature.

[0029] In addition, the two temperature sensors are both arranged in the central area of the medicine frying chamber 202 .

[0030] It should be noted that the temperature of the material in the stir-frying chamber 202 is monitored by two temperature sensors, wherein the temperature warning value of one temperature sensor is set to the temperature at which the material is desired to be heated, and the temperature warning value of the other temperature sensor is set to the temperature at which the material is desired to be heated plus 5°C. Under normal circumstances, when the temperature of the material in the stir-frying chamber 202 reaches the specified temperature, one temperature sensor gives an alarm and turns off the fire of the heating device 30, and after the temperature of the medicinal material in the stir-frying chamber 202 drops to the predetermined temperature, the heating device 30 is turned on and the medicinal material is heated to the specified temperature again, thereby achieving dynamic constant temperature of the material; if the previous temperature sensor fails or the heating device 30 fails, such as the flame of the open flame is too large, resulting in overheating during the heating of the medicinal material, at this time, the other temperature sensor set to add an additional 5°C gives an alarm and cools the overheated medicinal material in time.

[0031] It should be noted that since the temperature sensor is arranged in the central area of the medicine frying chamber 202, and since the cooling efficiency of the medicinal materials located inside is lower than that of the medicinal materials located outside, the temperature of the medicinal materials located inside cannot accurately reflect the temperature of the materials on the outside, that is, the temperature of the medicinal materials located outside is usually lower than that of the medicinal materials located inside due to faster cooling, which is not conducive to constant temperature control of all medicinal materials.

[0032] In view of this, in the present application, the central axis 201 has a circulation channel 2011, one end of the circulation channel 2011 extends into the medicine frying chamber 202 and is connected to or closed with the medicine frying chamber 202 through an electric control valve, and the other end of the circulation channel 2011 is connected to or closed with the outside through a normally open electric control valve, and the circulation channel 2011 is a through hole with both ends passing through.

[0033] It should be noted that by providing the central shaft 201 extending into the medicine frying cavity 202 and providing the circulation passage 2011, when it is necessary to cool the medicinal materials, the circulation passage 2011 is made to communicate with the medicine frying cavity 202 and the outside respectively, so that the central area of the medicine frying cavity 202 exchanges heat with the outside, and thus the temperature of the material in the central area tends to be the same as that of the material on the outside, facilitating the temperature sensor to accurately reflect the temperature of the material in the medicine frying cavity and perform dynamic constant temperature control of the material.

[0034] Furthermore, when the material is in an overheated state, to facilitate the cooling of the material, as Figure 2 and Figure 3 shown, the medicine frying machine for dynamically controlling the constant temperature of the material further includes a rotating member 40 and an overheat cooling device 50.

[0035] Specifically, the rotating member 40 is rotatably mounted on the base body 10. The rotating member 40 has a cooling area 401 and a transfer area 402. A cylinder 403 is fixedly mounted on both the cooling area 401 and the transfer area 402. A first feed pipe 404 is provided between the cylinder 403 on the cooling area 401 and the rotary drum 20, and a second feed pipe 405 is provided between the cylinder 403 on the transfer area 402 and the rotary drum 20. A socket 4031 is provided at the center of one end of each cylinder 403. In addition, the overheat cooling device 50 is disposed opposite to the cylinder 403 on the cooling area 401 and is used to cool the cylinder 403 on the cooling area 401.

[0036] It should be emphasized that the overheat cooling device 50, the first feed pipe 404, and the second feed pipe 405 do not rotate with the rotating member 40. The position of the overheat cooling device 50 opposite to the rotating member 40 is the cooling area 401, and the area located above the cooling area 401 and higher than the rotary drum 20 and symmetrically arranged with the cooling area 401 in the height direction is the transfer area 402.

[0037] It should be noted that when another sensor triggered at the specified temperature plus 5°C, that is, when the medicinal materials in the frying chamber 202 are heated to a slightly overheated state exceeding the specified temperature, the medicinal materials in the frying chamber 202 can pass through the first feed pipe 404 and be placed in the cylinder 403 on the cooling zone 401; in addition, it should be pointed out that another batch of medicinal materials that need to be heated in the same batch pass through the second feed pipe 405 from the transfer zone 402 and enter the frying chamber 202 of the rotary drum 20 at this time; it should be emphasized that since the frying chamber 202 is still in a high temperature state after heating at this time, the heat energy that has not dissipated can be used more quickly to heat the newly entered medicinal materials, and the medicinal materials that enter the cooling zone 401 are cooled at the same time through the overheating and cooling device 50. When the temperature of the medicinal materials in the cooling zone 401 drops to the specified temperature and the newly entered medicinal materials in the frying chamber 202 are heated to the specified temperature, the rotating member 40 is rotated 180°. At this time, the cylinder 403 originally located on the cooling zone 401 is located on the transfer zone 402 after the rotation of the rotating member 40. Subsequently, the medicinal materials placed in the frying chamber 202 can enter the cylinder 403 originally located on the transfer zone 402 through the first feed pipe 404; subsequently, since the space in the frying chamber 202 is vacated again, the medicinal materials in the cylinder 403 that have been rotated 180° and were originally located on the cooling zone 401 and are now located on the transfer zone 402 can enter the frying chamber 202 through the second feed pipe 405 for further heating. It is easy to see that in the above process, the waste heat in the frying chamber 202 is fully utilized, and a separate cooling zone 401 for cooling the medicinal materials is provided. Compared with the prior art, it has the advantages of multi-chamber, with an overheating and cooling device, and higher utilization rate.

[0038] Further, referring to Figure 1 and Figure 2The material dynamic constant temperature medicine frying machine also includes an air pumping device 60 and an outer cylinder 102. Each end of the cylinder 403 away from the plug hole 4031 has a first drop opening 4032, and each side wall of the cylinder 403 has a second drop opening 4033. The outer cylinder 102 is sleeved on the outside of the rotating cylinder 20 and fixedly installed on the base 10. The outer cylinder 102 has a first discharge opening 1021. The end of the rotating cylinder 20 close to the central axis 201 has a plurality of second discharge openings 203. One end of the first feed pipe 404 passes through the heating chamber 101 and is opposite to the first discharge opening 1021. The other end of the first feed pipe 404 is opposite to the first drop opening 4032 on the cylinder 403 located in the cooling zone 401. One end of the second feed pipe 405 passes through the heating chamber 101 and is connected with the end of the circulation channel 2011 away from the medicine frying chamber 202. Specifically, the circulation channel 2011 has a normally closed hole with an electric control valve. When one end of the second feed pipe 405 is facing the hole on the circulation channel 2011, one end of the second feed pipe 405 is connected with the circulation channel 2011, and the other end of the second feed pipe 405 is facing the second material drop port 4033. The first material drop port 4032, the second material drop port 4033 and the end of the first feed pipe 404 close to the first discharge port 1021 are all provided with electric control valves. The air pumping device 60 extends into the end of the circulation channel 2011 away from the medicine frying chamber 202 and is connected with the circulation channel 2011.

[0039] It should be noted that when the medicinal materials in the frying chamber 202 need to be transferred to the cylinder 403 located on the cooling area 401, by opening the electric control valve on the first blanking port 4032 of the cylinder 403 located in the cooling area 401 and the electric control valve on the end of the first feed pipe 404 close to the first discharge port 1021, then as the rotary drum 20 rotates, the medicinal materials in the frying chamber 202 fall into the second discharge port 203 during the rotation of the rotary drum 20. After the second discharge port 203 is aligned with the first discharge port 1021, the medicinal materials in the frying chamber 202 successively pass through the first discharge port 1021 and the second discharge port 203, and fall into the cylinder 403 located on the cooling area 401 through the first feed pipe 404 via the first discharge port 1021. Additionally, by closing the electric control valves at both ends of the circulation channel 2011, opening the electric control valve on the second blanking port 4033 of the cylinder 403 located in the transfer area 402, rotating the central shaft 201 to a predetermined angular position so that the second feed pipe 405 is aligned with the hole on the central shaft 201, and the normally closed electric control valve on the hole is opened, and then turning on the air pumping device 60, at this time, the air pumping device 60 pumps air into the cylinder 403 located in the transfer area 402 along the circulation channel 2011 and the second feed pipe 405, sucks the medicinal materials therein into the circulation channel 2011, then by opening the electric control valve on the end of the circulation channel 2011 communicating with the frying chamber 202, closing the normally closed electric control valve on the hole of the central shaft 201, and making the air pumping device 60 supply air into the circulation channel 2011, and blowing the medicinal materials in the circulation channel 2011 into the frying chamber 202.

[0040] Furthermore, to prevent the medicinal materials from being drawn out when pumping air into the circulation channel 2011, a filter screen for blocking the medicinal materials is provided in the circulation channel 2011.

[0041] Furthermore, to cool the cylinder 403 on the cooling area 401, as Figure 3 and Figure 4As shown, the overheating cooling device 50 includes a second rotary motor 501, a first rotating shaft 502, a clutch 503, a lead screw 504, a slider 505, a second rotating shaft 506, a blower 507, a sleeve 508, a third rotating shaft 509, a distance sensor 5010 and a controller. The blower 507 and the sleeve 508 are both installed on the slider 505. The sleeve 508 has a receiving cavity 5081. The side wall of the receiving cavity 5081 has an air inlet and an air outlet. The air outlet direction of the blower 507 faces the air inlet. The lead screw 504 and the slider 505 are connected by a lead screw 504-slider 505 connection. The rotating shaft of the second rotary motor 501 is fixedly connected to the first rotating shaft 502. The first rotating shaft 502 is connected to the lead screw 504 through the clutch 503. The slider 505 is slidably arranged on the seat body 10, and a guide rod connected to the seat body 10 is passed through the slider 505. The second rotating shaft 506 is rotatably installed on the slider 505. The third rotating shaft 509 is rotatably installed on the seat body 10. Gears are provided on the first rotating shaft 502, the second rotating shaft 506 and the third rotating shaft 509. The other end of the third rotating shaft 509 is connected to the rotating member 40 through belt drive. The distance sensor 5010 and the clutch 503 are both electrically connected to the controller. In addition, a plug rod 5082 is further provided at the center of the sleeve 508. The plug rod 5082 is directly opposite to the jack 4031 on the cylinder body 403 located in the cooling area 401. The plug rod 5082 has a refrigerant channel. The refrigerant channel is communicated with an external refrigerant device through an FEP spring tube. Both temperature sensors are connected to the controller.

[0042] It should be noted that under normal conditions, when the coil of the clutch 503 is energized and the first rotating shaft 502 rotates, the lead screw 504 rotates accordingly. When the rotating shaft of the second rotating motor 501 rotates, the lead screw 504 rotates accordingly, drives the slider 505 to move along the axial direction of the lead screw 504, and makes the sleeve 508 mounted on the slider 505 sleeved on the cylinder body 403 located in the cooling area 401 or makes the sleeve 508 disengaged from the cylinder body 403. It should be noted that when cooling the cylinder body 403 in the cooling area 401, the sleeve 508 is sleeved on the cylinder body 403 located in the cooling area 401, and the fan 507 operates, then the gas flows from the air inlet to the air outlet direction, flows through the outer wall of the cylinder body 403, and takes away heat; meanwhile, the insertion rod 5082 is inserted into the jack 4031, and the external refrigerant flows into the refrigerant channel of the insertion rod 5082, and further exchanges heat with the medicinal materials in the cylinder body 403 through the insertion rod 5082; before the rotating member 40 rotates 180°, by reversing the rotating shaft of the second rotating motor 501 and driving the sleeve 508 to disengage from the cylinder body 403, the movement interference between the sleeve 508 and the cylinder body 403 on the rotating member 40 is avoided.

[0043] It should also be emphasized that when the slider 505 moves towards the second rotating motor 501 and makes the sleeve 508 disengage from the cylinder body 403, the gear on the second rotating shaft 506 meshes with the gear on the first rotating shaft 502 first. It should be pointed out that although the gear on the second rotating shaft 506 does not rotate when the slider 505 moves, since the gear on the first rotating shaft 502 is always in a rotating state, and the gear on the second rotating shaft 506 moves towards the first rotating shaft 502 at this time, then at a certain moment, the tooth groove of the gear on the rotating first rotating shaft 502 is aligned with the meshing tooth part of the gear on the second rotating shaft 506, and the gears on the first rotating shaft 502 and the second rotating shaft 506 mesh.

[0044] In addition, as Figure 4 shown, the gear on the third rotating shaft 509 is located on the side of the gear on the first rotating shaft 502 away from the slider 505. The thickness of the gear on the second rotating shaft 506 is the sum of the thicknesses of the gears on the first rotating shaft 502 and the third rotating shaft 509.

[0045] It should be noted that after the gears on the first rotating shaft 502 and the second rotating shaft 506 are engaged, the rotation of the first rotating shaft 502 will drive the rotation of the second rotating shaft 506. At this time, the gear on the second rotating shaft 506 is also in a state of circumferential rotation. Since the slider 505 still moves towards the second rotating motor 501 at this time, the gear on the second rotating shaft 506 will contact the gear on the third rotating shaft 509 at a certain moment. And at a certain moment, the tooth groove of the gear on the second rotating shaft 506 is aligned with the meshing tooth part of the gear on the third rotating shaft 509, and the gear on the second rotating shaft 506 is engaged with the gear on the third rotating shaft 509. At this time, the third rotating shaft 509 makes a circumferential rotation and drives the rotating member 40 to make a circumferential rotation through belt transmission, so that the rotating member 40 rotates 180°. It should also be emphasized that when the gear on the second rotating shaft 506 is engaged with the gear on the third rotating shaft 509 to a predetermined degree, the distance between the end face of the second rotating shaft 506 and the distance sensor 5010 is less than the set value. At this time, the controller receives the signal from the distance sensor 5010 and makes the coil of the clutch 503 de-energized. Then, the circumferential rotation of the first rotating shaft 502 no longer drives the screw rod 504 to make a circumferential rotation, avoiding the axial movement of the slider 505 during the 180° rotation of the rotating member 40.

[0046] In addition, there are two light holes 406 arranged centrally symmetrically on the rotating member 40, and several light sensors are provided on the seat body 10. When the rotating member 40 rotates a predetermined angle and is arranged obliquely, the light sensors are aligned with the light holes 406, and the light sensors are electrically connected to the controller.

[0047] It should be noted that when the rotating member 40 rotates, the light is blocked by the light sensors. When the rotating member 40 rotates to nearly 180°, the light sensors are aligned with the light holes 406 and send an electrical signal to the controller once. After receiving the signal, the controller makes the coil in the clutch 503 energized, and makes the rotating shaft of the second rotating motor 501 rotate circumferentially along the original direction. Then, the rotation of the first rotating shaft 502 will drive the screw rod 504 to rotate, and make the sleeve 508 move towards the rotating member 40 again. It should also be pointed out that when the gear on the second rotating shaft 506 is separated from the gear on the third rotating shaft 509, the rotating member 40 just rotates to 180° and is arranged vertically. At this time, the rotation of the first rotating shaft 502 will only drive the screw rod 504 to rotate and make the sleeve 508 move towards the cylinder body 403.

[0048] In addition, a limit switch is provided at one end of the slider 505 facing away from the second rotating motor 501. When the sleeve 508 is sleeved on the cylinder body 403 located in the cooling area 401, the limit switch is triggered and the second rotating motor 501 is powered off.
