Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine processing equipment, in particular to a uniformly heated processing equipment for Chinese medicine pieces. Background Art

[0002] The processing technology of Chinese herbal medicine slices is a core pharmaceutical technology based on the theory of traditional Chinese medicine. It optimizes the pharmacological activity (enhancing efficacy and reducing toxicity) and clinical effects of Chinese herbal medicines by performing specific processing on Chinese herbal medicines in accordance with the characteristics of the medicines, clinical needs, and special requirements of blending and preparation. The processing methods include roasting, frying, boiling, stewing, baking, and simmering. In the existing technology, Chinese herbal medicines are often sliced ​​before frying. Since the coarseness of Chinese herbal medicines varies, the size of the slices produced also varies. The existing frying machines are not very effective in frying Chinese herbal medicine slices. During the production process, all slices of different sizes are heated and fried uniformly. The moisture in small slices is easy to evaporate during frying, while large slices need longer time to fry. Such frying will cause smaller slices (small Chinese herbal slices) to be over-fried. Over-frying of Chinese herbal slices will lead to excessive carbonization of Chinese medicine, thus affecting the efficacy. Large slices (large Chinese herbal slices) are not fried enough, and even the toxicity of Chinese herbal slices has not been removed if they are not fried well, which will cause harm to the patient's body after drinking. Both situations will affect the quality and efficacy of the Chinese herbal slices after production. Summary of the invention

[0034] After research, it was found that in the existing technology, when frying Chinese medicine, the Chinese medicine is often sliced ​​and then fried. Since the thickness of Chinese medicine itself varies, the size of the slices made is also different. When Chinese medicine pieces of different sizes are fried uniformly, small Chinese medicine pieces are easy to fry (short frying time), while large Chinese medicine pieces are difficult to fry (long frying time). If they are mixed and fried in this way, small Chinese medicine pieces may be over-fried (over-carbonized), affecting the quality of the Chinese medicine pieces, while large Chinese medicine pieces may be under-fried, resulting in incomplete removal of their toxicity, which will cause harm to the patient's body after drinking.

[0036] like Figure 2-Figure 4As shown, the switching mechanism 11 includes a first fixed frame 1101, which is fixedly connected to the front side of the heating shell 2. A first electric rotating shaft 1102 is arranged on the first fixed frame 1101. The two second material blocking plates 7 are commonly spline-connected with a spline shell 1103.

[0037] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the material distribution mechanism 12 includes a fixed shell 1201 for connecting Chinese herbal medicine slices, an equidistantly distributed pipeline is arranged on the upper side of the heating shell 2, the fixed shell 1201 is fixedly connected to the equidistantly distributed pipeline on the upper side of the heating shell 2, and the lower side of the fixed shell 1201 is connected to the stir-frying shell 3 through the equidistantly distributed pipeline on the upper side of the heating shell 2. The inner side of the fixed shell 1201 is rotatably connected to the first rotating shell 1202, and the lower side of the first rotating shell 1202 is provided with equidistantly distributed through holes. The inner side of the first rotating shell 1202 is rotatably connected to the second rotating shell 1203, and the left sides of the first rotating shell 1202 and the second rotating shell 1203 are both provided with through holes, and the front side of the second rotating shell 1203 is also provided with equidistantly distributed through holes, and the through holes on the first rotating shell 1202 are staggered with the through holes on the second rotating shell 1203, and the first rotating shell 1202 is connected to the stir-frying shell 3 through the equidistantly distributed pipeline. The through hole on 202 and the through hole on the second rotating shell 1203 are deflected at an angle of 90° in the circumferential direction. Both the first rotating shell 1202 and the second rotating shell 1203 are truncated cone-shaped shells, and the diameter gradually increases from left to right. The first screening plate 1204 and the second screening plate 1205 are fixedly connected to the inner side of the second rotating shell 1203. The first screening plate 1204 is used to isolate large-sized Chinese herbal medicines, and the second screening plate 1205 is used to isolate medium-sized Chinese herbal medicines. The first screening plate 1204 and the second screening plate 1205 are both provided with evenly distributed through holes, and the aperture of the through holes on the first screening plate 1204 is larger than the aperture of the through holes on the second screening plate 1205. A second electric shaft 1206 is provided on the right side of the pipeline on the right side of the heating shell 2, and the second electric shaft 1206 is transmitted to the first rotating shell 1202 through a spur gear set.

[0038] like Figure 5 and Figure 6As shown, a second fixing frame 1207 is fixedly connected to the right side of the first rotating shell 1202, and the second fixing frame 1207 is composed of a circular ring and a straight plate. A fixing plate 1208 is fixedly connected to the right side of the second rotating shell 1203, and the fixing plate 1208 is slidably connected to the circular ring part of the second fixing frame 1207. A tension spring is arranged between the lower side of the fixing plate 1208 and the straight plate part of the second fixing frame 1207, and the initial state of the tension spring between the lower side of the fixing plate 1208 and the straight plate part of the second fixing frame 1207 is a stretched state. A third fixing frame 1209 is fixedly connected to the right side of the first rotating shell 1202, and the third fixing frame 1209 is rotatably connected to a threaded rod 1210, and the threaded rod 1210 is threadedly connected to a limit block 1211 slidably connected to the third fixing frame 1209, and the limit block 12 11 is limited in cooperation with the fixed plate 1208, and a blocking block 1212 is fixedly connected to the inside of the right side of the first rotating shell 1202, and the blocking block 1212 is limited in cooperation with the fixed plate 1208. When the limiting block 1211 loses the limiting position on the fixed plate 1208, the tension spring between the fixed plate 1208 and the straight plate part of the second fixed frame 1207 drives the fixed plate 1208 to slide on the circular ring part of the second fixed frame 1207 until the fixed plate 1208 contacts the blocking block 1212 for limiting again. When the tension spring between the fixed plate 1208 and the second fixed frame 1207 is of the original length, the angle between the two ends in the circumferential direction is smaller than the angle between the blocking block 1212 and the straight plate part of the second fixed frame 1207 in the circumferential direction, which is used to ensure that the relative position of the first rotating shell 1202 and the second rotating shell 1203 remains unchanged.

[0039] like Figure 4 , Figure 7 and Figure 8 As shown, the flipping mechanism 13 includes evenly distributed blocking plates 1301, the cross section of the blocking plates 1301 is L-shaped, and is used to strengthen the fixation of the Chinese herbal medicine slices. The evenly distributed blocking plates 1301 are all fixed to the inner side of the stir-fry shell 3, and the inner side of the stir-fry shell 3 is rotatably connected with evenly distributed flip plates 1302, and the flip plates 1302 are embedded in the inner side of the stir-fry shell 3. In a normal state, the flip plates 1302 are flush with the inner side of the stir-fry shell 3, and there is a gap between the flip plates 1302 and the stir-fry shell 3. A torsion spring is provided, and a first magnet 1303 is fixedly connected to one side of the flap 1302 close to the heating shell 2. The blocking plate 1301, the adjacent flap 1302 and the adjacent first magnet 1303 together form a single module, and the module is evenly distributed in the stir-fry shell 3. A second magnet 1304 is fixedly connected to the heating shell 2, the first magnet 1303 and the second magnet 1304 are magnetically matched, and the outer side surface of the first magnet 1303 and the inner side surface of the second magnet 1304 have the same magnetic pole.

[0040] When the device is needed to stir-fry Chinese herbal medicines, the user first injects sufficient water into the chamber of the heating shell 2 through the lower pipe of the heating shell 2, and then starts the electric heating plate in the chamber of the heating shell 2 to heat the water therein, and the preparation work is completed at this time.

[0041] When frying Chinese herbal medicine slices, if different sizes of Chinese herbal medicine slices are fried at the same time, the heating degree they receive at the same time is also different, which will lead to the quality of the finished product (Chinese herbal medicine slices) being reduced. In order to ensure that the different sizes of Chinese herbal medicine slices are heated to the same degree, the following operations need to be performed:

[0042] In order to speed up the screening efficiency of Chinese herbal medicines of different sizes, the user first puts the Chinese herbal medicines into the second rotating shell 1203 through the through hole on the left side of the first rotating shell 1202, and then the user starts the second electric shaft 1206, and the second electric shaft 1206 drives the first rotating shell 1202 to rotate through the gear set, and the first rotating shell 1202 drives the fixed plate 1208 to rotate through the third fixed frame 1209 and the limit block 1211, and the fixed plate 1208 drives the second rotating shell 1203 to rotate. Because the second rotating shell 1203 is a conical shell, and its cross-sectional area gradually increases from left to right, as the second rotating shell 1203 continues to rotate, the Chinese herbal medicines entering the second rotating shell 1203 move downward with gravity, and the area of ​​the Chinese herbal medicines is smaller than The Chinese herbal medicines with a single through-hole area among the evenly distributed through-holes on the first screening plate 1204 continue to move to the lower right side through the evenly distributed through-holes on the first screening plate 1204, and the Chinese herbal medicines with an area larger than the single through-hole area among the evenly distributed through-holes on the first screening plate 1204 are intercepted to the left side of the first screening plate 1204. The second screening plate 1205 further subdivides the Chinese herbal medicines in the same way, and in this process, the second rotating shell 1203 synchronously drives the first screening plate 1204 and the second screening plate 1205 to rotate synchronously, preventing the first screening plate 1204 and the second screening plate 1205 from being blocked, while speeding up the screening efficiency of the two for the Chinese herbal medicines. The user repeats the above steps until this batch of Chinese herbal medicines have been screened, and the screening step is ended at this time.

[0043] After the screening step is completed, the user closes the second electric rotating shaft 1206, and the user rotates the threaded rod 1210 at the same time. The threaded rod 1210 drives the limit block 1211 to move away from the second fixed frame 1207 through the thread until the limit block 1211 loses the limit on the fixed plate 1208. The tension spring between the fixed plate 1208 and the second fixed frame 1207 drives the fixed plate 1208 to slide along the circular ring part of the second fixed frame 1207 until the fixed plate 1208 contacts and is squeezed to the blocking block 1212. At this time, the switching is completed. During the sliding process of the above-mentioned fixed plate 1208, the fixed plate 1208 drives the second rotating shell 1203 to rotate until the fixed plate 1208 contacts and is squeezed to the blocking block 1212. The second rotating shell 1203 rotates 90°. At this time, the evenly spaced through holes on the second rotating shell 1203 are aligned with the evenly spaced through holes on the first rotating shell 1202.

[0044] When the equidistant through holes on the second rotating shell 1203 overlap with the equidistant through holes on the first rotating shell 1202, the Chinese herbal medicines divided into three different sizes move downward through the adjacent through holes respectively. At the same time, the user controls the second electric shaft 1206 to continuously rotate forward and reverse. The second electric shaft 1206 drives the first rotating shell 1202 and the second rotating shell 1203 to swing back and forth continuously through the gear set, thereby accelerating the unloading speed of the Chinese herbal medicines. The Chinese herbal medicines are guided downward to the inside of the stir-fry shell 3 by the adjacent pipes on the heating shell 2 until all the Chinese herbal medicines fall into the inside of the stir-fry shell 3, and the unloading step is completed at this time.

[0045] After the feeding step is completed, the user starts the motor 8, and the output shaft of the motor 8 drives the stir-fry shell 3 to rotate through the gear set, and the water in the heating shell 2 provides a stable temperature for the stir-fry shell 3. Because the stir-fry shell 3 is a truncated cone-shaped shell, and the volume of the large-sized Chinese herbal medicine chamber is larger than that of the medium-sized Chinese herbal medicine chamber, which is larger than that of the small-sized Chinese herbal medicine chamber. Therefore, in the process of the stir-fry shell 3 constantly rotating and stir-frying the Chinese herbal medicine slices, the overall heated area of ​​the small-sized Chinese herbal medicine slices is smaller than that of the medium-sized Chinese herbal medicine slices, which is smaller than the overall heated area of ​​the large-sized Chinese herbal medicine slices. Therefore, under the same heating time, the total area of ​​the stir-fry shell 3 contacted by the small-sized Chinese herbal medicine slices is smaller than that of the medium-sized Chinese herbal medicine slices, which is smaller than the total area of ​​the stir-fry shell 3 contacted by the large-sized Chinese herbal medicine slices, so as to ensure that the Chinese herbal medicine slices will not be over-stir-fried or under-stir-fried, thereby affecting the quality and efficacy of the Chinese herbal medicine slices.

[0046] In the above-mentioned stir-frying process, since the specific heat capacity of water in the heating shell 2 is large, the heating shell 2 heats the stir-frying shell 3 more evenly through water, thereby ensuring that the stir-frying shell 3 heats the Chinese herbal medicines at different positions therein evenly. When the stir-frying shell 3 rotates and heats and stir-fries the Chinese herbal medicines, taking large Chinese herbal medicines as an example, the stir-frying shell 3 drives the evenly distributed blocking plates 1301 therein to rotate, and the blocking plates 1301 drive the large Chinese herbal medicines to rotate when rotating. As the blocking plates 1301 gradually rotate, the blocking plates 1301 drive the large Chinese herbal medicines to gradually move upward. At this time, the large Chinese herbal medicines are located on the upper side of the adjacent flap 1302. When the flap 1302 adjacent to the blocking plate 1301 rotates to be at the same horizontal plane as the second magnet 1304, the flap 1302 is squeezed and pushed by the repulsive force between the second magnet 1304 and the adjacent first magnet 1303. 2 swings, and twists the torsion spring between the flap 1302 and the stir-fry shell 3, the flap 1302 drives the large-sized Chinese herbal medicine slices to swing together, and the upper side of the large-sized Chinese herbal medicine slices is first flipped downward, so that the large-sized Chinese herbal medicine slices are turned over, to prevent the large-sized Chinese herbal medicine slices from being heated on one side for a long time, resulting in the quality of the finished products (and Chinese herbal medicine slices) being reduced, and the rotation direction of the stir-fry shell 3 is counterclockwise as the main direction when viewed from the left, and at the same time, the user controls the first electric rotating shaft 1102 to rotate, the first electric rotating shaft 1102 drives the spline shell 1103 to rotate through the pulley and the belt, and the spline shell 1103 and the stir-fry shell 3 have the same rotation speed and direction, the spline shell 1103 drives the two second material blocking plates 7 to rotate, and the stir-fry shell 3 drives the two first material blocking plates 6 to rotate, so as to continuously divide the stir-fry shell 3 into three chambers of large-sized Chinese herbal medicine slices, medium-sized Chinese herbal medicine slices and small-sized Chinese herbal medicine slices, to ensure the quality of the Chinese herbal medicine slices when stir-frying.

[0047] As the Chinese medicinal pieces of different sizes in the stir-fry shell 3 are continuously heated and fried, the water in the Chinese medicinal pieces is continuously lost, and the Chinese medicinal pieces gradually become wrinkled, which makes it difficult for the inward concave part of the Chinese medicinal pieces to contact the surface of the stir-fry shell 3 and be heated, resulting in uneven heating of the Chinese medicinal pieces, affecting the quality of the finished product. To solve the above problem, the following operations need to be performed:

[0048] When the Chinese herbal medicine slices continue to be fried, the stir-fry shell 3 continuously drives the inner protrusion 10 to rotate. If wrinkles appear on the Chinese herbal medicine slices, the protrusion 10 can still contact the inner concave part of the Chinese herbal medicine slices and heat them, thereby ensuring that the inner concave part of the Chinese herbal medicine slices is also heated, thereby ensuring that the Chinese herbal medicine slices are heated evenly during heating, thereby improving the quality of the finished product.

[0049] During the frying process of the Chinese herbal medicine slices, the hot steam generated in the frying shell 3 floats upward and dissipates to the outside through the upper through hole of the first rotating shell 1202 and the left through hole of the second rotating shell 1203 on the heating shell 2.

[0050] In order to evenly distribute the Chinese herbal medicines in each chamber of the stir-fry shell 3, when the stir-fry shell 3 rotates and stir-fries the Chinese herbal medicines, the Chinese herbal medicines move to the lower left due to their own gravity, and as the stir-fry shell 3 drives the evenly distributed inclined plates 9 therein to rotate continuously, the evenly distributed inclined plates 9 continuously squeeze and drive the Chinese herbal medicines on the lower left side to move to the upper right side, so the Chinese herbal medicines also form a cycle of upper left side-lower right side-upper left side in the chamber of the stir-fry shell 3, further increasing the uniformity of heating of the Chinese herbal medicines when stir-frying in the stir-fry shell 3.

[0051] When frying is finished, the user stops heating the heating plate in the heating shell 2, and at the same time, the user controls the motor 8 to drive the stir-fry shell 3 and the first material blocking plate 6 therein to reset and stop rotating, the user controls the first electric shaft 1102 to drive the second material blocking plate 7 to reset, and then the user stops the motor 8 and the first electric shaft 1102, and the user controls the first electric shaft 1102 to drive the spline shell 1103 to rotate 90°. At this time, the first material blocking plate 6 and the adjacent second material blocking plate 7 lose the blockage of the inner chamber of the stir-fry shell 3, the user controls the telescopic end of the electric push rod 4 to extend, and the telescopic end of the electric push rod 4 drives the cover plate 5 to move to the left until the cover plate 5 loses the blockage of the stir-fry shell 3, and then use The user simultaneously controls the motor 8 and the first electric shaft 1102 to reverse, the motor 8 drives the stir-fry shell 3 to reverse, the stir-fry shell 3 drives the evenly distributed inclined plates 9 therein to rotate, and with the rotation of the stir-fry shell 3, the medium-sized Chinese herbal medicines and the small-sized Chinese herbal medicines move to the left through the gap between the adjacent first material blocking plate 6 and the adjacent second material blocking plate 7, the Chinese herbal medicines in the stir-fry shell 3 move to the left under their own gravity and the driving of the inclined plate 9 and gradually move to the left out of the stir-fry shell 3 until all the Chinese herbal medicines are discharged, at which time the unilateral preparation of the Chinese herbal medicines is completed, and then the user continues to repeat the above steps to stir-fry the remaining unprocessed Chinese herbal medicines until all the Chinese herbal medicines are fried and the use of the device is completed.

[0052] Embodiment 2: Based on embodiment 1, Figure 2 , Fig. 9 and Fig.10As shown, a heat exchange mechanism 14 for utilizing the waste heat of steam is also included. The heat exchange mechanism 14 is arranged on the frame 1. The heat exchange mechanism 14 includes a heat exchange shell 1401. The cross section of the heat exchange shell 1401 is composed of a rectangle and an isosceles trapezoid. The isosceles trapezoid part is used to collect condensed water generated by steam heat exchange. The heat exchange shell 1401 is fixed to the upper side of the frame 1. The left side of the heat exchange shell 1401 is connected with two air outlet pipes 1402 distributed in front and back mirror images. The air outlet pipe 1402 is used to transfer steam into the heat exchange shell 1401. The air outlet pipe 1402 is connected to the stir-fry shell 3 through three pipes equidistantly distributed on the upper side of the heating shell 2. The heat exchange The shell 1401 is fixedly connected with an air inlet pipe 1403, which is connected to an external air supply system. The part of the air inlet pipe 1403 located inside the heat exchange shell 1401 is a serpentine pipe, which is used to increase the heat exchange efficiency between the dry gas and the hot steam therein. The lower side of the air inlet pipe 1403 is rotatably connected to the stir-fry shell 3, and the air inlet pipe 1403 is rotatably connected and connected to the spline shell 1103. An insulation layer is provided on the outer side of the part of the air inlet pipe 1403 located between the heat exchange shell 1401 and the spline shell 1103, which is used to keep the dry gas after heat exchange warm. The spline shell 1103 is provided with through holes that are equidistant and distributed in a circumferential array.

[0053] like Figure 9-13 As shown, the inner side of the spline shell 1103 is fixedly connected with a fourth fixing frame 1404 which is evenly distributed on the left and right sides. The evenly distributed fourth fixing frames 1404 are slidably connected together with three evenly distributed air blocking plates 1405. The air blocking plates 1405 have an arc-shaped cross section and fit with the inner side of the spline shell 1103 to ensure sealing. The inner side of the spline shell 1103 is fixedly connected with a fixing plate 1406, and the fixing plate 1406 is provided with three evenly distributed arc-shaped sliding grooves. The air blocking plates 1405 and the adjacent arc-shaped sliding grooves on the fixing plate 1406 are limited. The deflection angles of the two ends of the arc-shaped groove on the fixed disk 1406 in the circumferential direction differ by 90°, which is used to ensure the matching state of the air blocking plate 1405 and the adjacent and equidistantly distributed through holes on the spline shell 1103. A fixing rod 1407 is fixedly connected to the left side of the fixed disk 1406, and the spline shell 1103 and the first fixing frame 1101 are both rotatably connected to the fixing rod 1407. A conversion sleeve 1408 is spline-connected to the left side of the fixing rod 1407, and the spline shell 1103 and the first fixing frame 1101 are both spline-matched with the conversion sleeve 1408.

[0054] When the existing medicine frying machine is frying the Chinese medicine pieces, the moisture in the Chinese medicine pieces turns into water vapor and drifts away, but the residual heat contained in the water vapor is not recovered. In order to make full use of the residual heat in the water vapor, the following operations need to be performed:

[0055] After the unloading step is completed, the user controls the fixing plate 1208 to drive the second rotating shell 1203 to reset, and at the same time stretches the tension spring between the fixing plate 1208 and the second fixing frame 1207, and then the user reverses the threaded rod 1210, and the threaded rod 1210 drives the limit block 1211 to reset and limit the fixing plate 1208. When frying, every time the stir-fry shell 3 rotates a circle, the through hole on the stir-fry shell 3 is connected with the two air outlet pipes 1402 through the heating shell 2, and the steam in the stir-fry shell 3 flows into the heat exchange shell 1401 through the heating shell 2 and the two air outlet pipes 1402. At the same time, the user supplies the heat through the outside The air system injects dry air into the air inlet pipe 1403. After the steam enters the heat exchange shell 1401, it moves upward and exchanges heat with the dry air in the air inlet pipe 1403. The heated dry air flows downward to the spline shell 1103, and flows into the stir-fry shell 3 along the evenly distributed through holes on the spline shell 1103, thereby reducing the air humidity in the stir-fry shell 3 and accelerating the efficiency of water analysis in the Chinese herbal medicine slices. After the heat exchange is completed, the water vapor condenses into water droplets, which continuously drip in the heat exchange shell 1401 and flow to the collection system through the pipe on the lower side thereof, while the remaining gas flows to the outside through the pipe above it.

[0056] When discharging after frying, the following operations are required to ensure that the discharged Chinese herbal medicine pieces are in a dry state and to reduce the subsequent drying time:

[0057] After the frying of the Chinese herbal medicine slices is completed and the cover plate 5 loses the limit on the stir-fry shell 3, the user controls the conversion sleeve 1408 to move left, until the conversion sleeve 1408 loses the coordination with the fixing rod 1407 and is spline-connected with the first fixing frame 1101 and the fixing rod 1407 at the same time, the user controls the first electric rotating shaft 1102 to drive the spline shell 1103 to rotate 90° counterclockwise (with the left as the main direction), and the spline shell 1103 drives the three air blocking plates 1405 to rotate 90° counterclockwise synchronously through the fourth fixing frame 1404 evenly distributed therein. When the three air blocking plates 1405 rotate 90° counterclockwise, the blocking plates 1405 are limited by the adjacent arc-shaped grooves on the fixing plate 1406 and move outward until the rotation is completed. The three air blocking plates 1405 block all the through holes evenly distributed in three directions on the spline shell 1103. At this time, the spline shell 1103 Only the through holes evenly distributed in one direction can flow dry hot air to the outside of the stir-fry shell 3, and then the user controls the conversion sleeve 1408 to move to the right and reset, and the user repeats the above steps to perform the discharge operation. When discharging, since the flow area from the spline shell 1103 to the stir-fry shell 3 is reduced, the gas flow rate blown out from the only side of the spline shell 1103 increases, thereby increasing the blowing force on the Chinese herbal medicines, and the spline shell 1103 continuously rotates to evenly blow the Chinese herbal medicines in the stir-fry shell 3, thereby blowing out the hot and humid gas between the Chinese herbal medicines and cooling and drying them, reducing the subsequent cooling and drying steps of the Chinese herbal medicines. When the discharge is completed, the user controls the three air blocking plates 1405, the two first material blocking plates 6 and the two second material blocking plates 7 to reset through the conversion sleeve 1408 and the first electric shaft 1102, and continues to repeat the above preparation steps to prepare the Chinese herbal medicines.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope.
