Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a stir-frying machine for processing Chinese medicinal herbs. Background Technology

[0002] Prepared Chinese medicinal herbs refer to prescription drugs that have been processed from Chinese medicinal materials and can be directly used in clinical practice or pharmaceutical production in traditional Chinese medicine. They are a core component of clinical medication in traditional Chinese medicine. They are processed products made from Chinese medicinal materials under the guidance of traditional Chinese medicine theory, through cleaning, cutting, and roasting, and meet the requirements for clinical medication.

[0003] Traditional Chinese medicine (TCM) decoction pieces are processed TCM herbs that can be directly used in TCM clinical practice. They include some processed TCM slices, raw medicinal herbs, and processed decoction pieces. TCM stir-frying, also known as stir-frying, is a method of stir-frying raw herbs without adding excipients after cleaning or cutting. TCM stir-frying can improve the medicinal properties and efficacy, reduce toxicity, and prolong storage time.

[0004] An existing application with application number 202321391732.9 discloses a stir-frying machine for processing Chinese medicinal herbs, which includes an induction cooker and a wok. The wok is mounted on top of the induction cooker, and a base is provided on one side of the induction cooker. A hydraulic rod is fixedly connected to the top of the base. A crossbeam is fixedly connected to the top of the output end of the hydraulic rod. The crossbeam is arranged horizontally, and a motor is fixedly connected to the top of the crossbeam.

[0005] The aforementioned stir-frying machine uses a combination of a rotating rod and a stirring blade to stir-fry Chinese medicinal herbs. However, the stirring blade directly contacts the herbs during the turning process, and the stirring action can easily cause mechanical damage to brittle or uniquely shaped herbs, resulting in compromised integrity. This damage not only affects the appearance of the herbs but may also disrupt their internal structure, reducing their efficacy. Furthermore, due to the turning action of the stirring blades, a certain amount of herb debris is inevitably generated during the stir-frying process. This debris remains in the wok after stir-frying and requires manual cleaning and separation. This cleaning process not only increases labor intensity and time costs but may also lead to waste and cross-contamination of herbs, affecting product quality and production efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a stir-frying machine for processing Chinese herbal medicine slices, so as to solve the problems mentioned in the background art, which are that the stir-frying slices push the Chinese herbal medicine to move and turn, which can easily cause mechanical damage to the Chinese herbal medicine, resulting in damage to the integrity of the medicine, destroying its structure and efficacy, and producing debris that needs to be cleaned manually, increasing labor intensity and cost.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stir-frying machine for processing Chinese herbal medicine slices includes an electric heating plate, a stir-frying vibration support device, a spiral conveying device, and a spiral protective shell. The spiral conveying device includes conveying spiral blades and a conveying shaft. The conveying spiral blades are installed on the outer circumferential wall of the conveying shaft. The conveying spiral blades include a first spiral blade and a second spiral blade. The electric heating plate is spirally embedded inside the first spiral blade and the second spiral blade. The electric heating plate is connected to an external power supply and temperature control device through wires.

[0009] Preferably, the stir-frying vibration support device includes a vibration motor, a support base, vibration springs, and a support top plate. The support base is rectangular in shape, the vibration springs are distributed around the top of the support base, the bottom of the support top plate is connected to the top of the vibration springs, the vibration motor is fixed on one side of the outer wall of the support base, and the vibration motor is connected to an external power supply device through a wire.

[0010] Preferably, the spiral protective shell is distributed in a spiral structure outside the conveying spiral blade, the outer circumferential wall of the conveying spiral blade abuts against the inner circumferential wall of the spiral protective shell, and a feed hopper is integrally connected to the bottom of the spiral protective shell.

[0011] Preferably, a drive motor is connected to the bottom of the conveyor shaft, passing through the feed hopper and the support top plate in sequence. The outer wall of the drive motor is connected to the support base, and the drive motor is electrically connected to an external power supply device through a wire.

[0012] Preferably, a feeding plate is connected to the top end of the spiral protective shell, and a dust removal fan is provided on the outer wall of the spiral protective shell located on one side of the feeding plate.

[0013] Preferably, a stir-frying channel is formed between the conveyor shaft and the spiral protective shell, and the stir-frying channel is 1.2-1.5 times longer than the maximum length of the medicinal material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The non-contact stir-frying design of this application differs from the traditional stir-frying machine where the stir-frying blades directly push the medicinal materials. The movement of the medicinal materials is achieved through the spiral stir-frying channel formed by the conveying spiral blades and the spiral protective shell of the spiral conveyor device. The medicinal materials move forward along the spiral channel under the drive of the conveying spiral blades, rather than being directly "stirred and pushed" by the blades. This avoids the breakage and fracture of fragile or specially shaped medicinal materials due to hard contact. The channel width is 1.2-1.5 times the maximum length of the medicinal materials, ensuring that the medicinal materials have enough space to turn over autonomously during movement, further reducing the risk of compression damage.

[0016] 2. Vibration-assisted uniform heating: The vibration motor and vibration spring in the stir-frying vibration support device cause micro-vibration in the entire stir-frying mechanism. Vibration can promote the loose distribution and turning of the medicinal materials in the spiral channel, avoid local accumulation, ensure that the heat of the electric heating plate is evenly transferred to each piece of medicinal material, reduce the loss of medicinal components caused by uneven heating, and the vibration can also make the medicinal materials turn naturally without external force to turn them, further reducing mechanical damage.

[0017] 3. The impurity removal fan on the top of the spiral protective shell can be started after roasting. It uses wind power to separate small debris from whole medicinal materials. The debris is blown away from the discharge path by the fan, while the whole medicinal materials fall and are collected due to their greater weight, realizing "discharge and impurity removal at the same time" without the need for manual screening.

[0018] 4. The conveying spiral blades are in close contact with the inner wall of the spiral protective shell, which can reduce the residue of medicinal materials and avoid the problem of debris sticking to the bottom of the pot in traditional woks and needing to be manually scraped.

[0019] 5. The electric heating plate is embedded inside the spiral blades and is distributed in a spiral shape, which increases the contact area with the medicinal materials. The heating path is consistent with the movement trajectory of the medicinal materials, realizing continuous stir-frying by "heating while conveying". The temperature control equipment is connected to the electric heating plate through wires, which can accurately control the temperature of the spiral channel to meet the stir-frying process requirements of different medicinal materials.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0028] Please see the appendix Figure 1-5As shown, a stir-frying machine for processing Chinese herbal medicine slices includes an electric heating plate 1, a stir-frying vibration support device 2, a spiral conveying device 3, and a spiral protective shell 4. The spiral conveying device 3 includes a conveying spiral blade 31 and a conveying shaft 32. The conveying spiral blade 31 is installed on the outer circumferential wall of the conveying shaft 32 and includes a first spiral blade 311 and a second spiral blade 312. The electric heating plate 1 is spirally embedded inside the first spiral blade 311 and the second spiral blade 312. The electric heating plate 1 is connected to an external power supply and temperature control device through wires, thus embedding the electric heating plate 1 and the spiral conveying blade 31 into a single unit. The spiral blade 312 adopts a hollow sandwich structure. The electric heating plate 1 is embedded between the two layers of blades in a spiral trajectory to form a "heating blade". The contact distance between the electric heating plate 1 and the medicinal material is shortened to 3-5mm, and the heat conduction efficiency is improved by more than 40%, avoiding the heat loss of traditional external heating (such as induction cookers). The conveying spiral blade 31 is both a conveying component and a heating source, reducing the space occupied by independent heating elements, reducing the size of the equipment, and facilitating transportation. The spiral protective shell 4 is distributed in a spiral structure outside the conveying spiral blade 31. The outer circumferential wall of the conveying spiral blade 31 abuts against the inner circumferential wall of the spiral protective shell 4. The bottom of the spiral protective shell 4 is integrally connected to the feed hopper 41. A feeding plate is connected to the top end of the spiral protective shell 4. A cleaning fan is installed on the outer wall of the spiral protective shell 4 on one side of the feeding plate. A stirring channel is formed between the conveyor shaft 32 and the spiral protective shell 4. The stirring channel is 1.2-1.5 times longer than the maximum length of the medicinal material. The medicinal material is moved through the spiral stirring channel formed by the conveyor spiral blades 31 and the spiral protective shell 4. The medicinal material moves along the spiral channel under the drive of the conveyor spiral blades 31, rather than being directly "stirred and pushed" by the blades. This avoids the breakage and fracture of fragile or specially shaped medicinal materials due to hard contact. The channel width is 1.2-1.5 times the maximum length of the medicinal material, ensuring that the medicinal material has enough space to turn over on its own during movement. To further reduce the risk of crushing damage, the bottom of the conveyor shaft 32 is connected to the feed hopper 41 and the support top plate 24, and a drive motor is connected to it. The outer wall of the drive motor is connected to the support base 22. The drive motor is electrically connected to the external power supply equipment through the wire. When the drive motor starts, it drives the conveyor shaft 32 and the conveying spiral blades 31 on its outer circumferential wall to rotate. The conveying spiral blades 31 are in close contact with the inner wall of the spiral protective shell 4, which can reduce the residue of medicinal materials. The Chinese medicine slices enter the bottom of the conveying spiral blades 31 through the feed hopper 41. Under the rotation of the conveying spiral blades 31, the Chinese medicine slices are lifted and conveyed. At the same time as lifting and conveying, the Chinese medicine slices are stir-fried by the heating plate 1.

[0029] The Chinese herbal medicine slices fall into the bottom of the spiral protective shell 4 through the feed hopper 41, and enter the spiral-shaped stir-frying channel formed by the conveying spiral blades 31 and the spiral protective shell 4. The drive motor starts, causing the conveying shaft 32 and the spiral blades 31 to rotate at a low speed (initial speed 10-20 r / min). Under the push of the first spiral blades 311, the herbs climb axially along the spiral channel, and at the same time come into contact with the preheating section (temperature 40-60℃) of the electric heating plate 1 embedded in the blade layer, removing the surface moisture of the herbs and softening some hard herbs (such as roots), preparing them for subsequent stir-frying. The herbs then enter the stir-frying section (middle section of the spiral) with the spiral blades. At this time, the speed of the conveying shaft increases to 20-50 r / min. At a speed of 80-200℃, the temperature of the electric heating plate frying section rises to 80-200℃ (adjustable according to process requirements). Since the contact distance between the heating plate and the medicinal material is only 3-5mm, the heat is directly conducted to the surface of the medicinal material through the blades, achieving rapid and uniform heating. As the rotation progresses, the medicinal material enters the curing section (the area near the feeding plate at the top of the spiral). The electric heating plate maintains a low temperature of 50-70℃, allowing the medicinal properties to slowly penetrate and solidify. The impurity removal fan starts, and the wind blows to the feeding plate along the tangential direction of the spiral channel, forming a 30° angle with the direction of the medicinal material discharge. The whole medicinal material is discharged due to its large weight, while small debris is blown by the wind to the impurity collection trough on the side wall of the protective shell, achieving simultaneous discharge and impurity removal.

[0030] The medicinal materials in this application achieve autonomous tumbling through the thrust of the spiral blades and the constraint of the channel, avoiding the hard squeezing of traditional stirring blades, and increasing the integrity rate of the medicinal materials to over 95%, which is especially suitable for fragile medicinal materials.

[0031] Furthermore, the integrated design of the electric heating plate 1 and the spiral blades improves heat transfer efficiency by 40% and reduces energy consumption by 20% for the same frying time; the segmented temperature control technology (preheating-frying-simmering) precisely matches the thermodynamic requirements of different medicinal materials.

[0032] Furthermore, the material discharge process simultaneously separates debris, achieving a 98% impurity removal efficiency, eliminating the need for manual sieving.

[0033] Please see the appendix Figure 1 and 5As shown, the stir-frying vibration support device 2 includes a vibration motor 21, a support base 22, vibration springs 23, and a support top plate 24. The support base 22 has a rectangular structure and serves as the base of the spiral conveying device 3. It is fixed to the bottom of the spiral protective shell 4 with bolts, allowing the vibration generated by the vibration motor 21 to be directly transmitted to the medicinal materials in the spiral channel, avoiding vibration attenuation in the traditional "independent support" structure. The vibration springs 23 are distributed around the top of the support base 22, and the bottom of the support top plate 24 is connected to the top of the vibration springs 23. The vibration springs 23 are variable diameter spiral springs (bottom). With a large diameter and a small top diameter, the spring stiffness automatically adapts to the vibration intensity within the vibration frequency range of 5-20Hz. During low-frequency vibration (≤10Hz), the flexible deformation of the spring absorbs the impact and protects the fragile medicinal materials. During high-frequency vibration (>10Hz), the spring stiffness is enhanced to ensure that the vibration energy is effectively transmitted to the spiral blades. The vibration motor 21 is fixed on the outer wall of one side of the support base 22. The vibration motor 21 is connected to the external power supply equipment through the wire. The vibration causes the medicinal materials to roll autonomously in the spiral channel without the need for the blades to be forcibly moved. The mechanical damage rate is reduced from 18% of traditional equipment to less than 5%.

[0034] The support base 22 is fixedly connected to the bottom of the spiral protective shell 4 by bolts to form a rigid whole. The vibration spring 23 is installed at the four corners of the top of the support base 22. The support top plate 24 is elastically connected to the support base 22 by springs. The bottom of the conveying shaft 32 of the spiral conveying device 3 passes through the support top plate and is connected to the drive motor. The vibration motor 21 starts to run and generates a composite vibration in the horizontal and vertical directions. The vibration energy is directly transmitted to the medicinal materials in the spiral channel through the support base → vibration spring → support top plate → spiral conveying device. The medicinal materials are automatically turned over by vibration without the need for the spiral blades to forcibly turn them.

[0035] This application's stir-frying vibration support device, through the integration of structural rigidity, spring nonlinearity, and intelligent control, breaks through the bottlenecks of traditional vibration systems in terms of energy transmission, damage control, and process adaptability. It provides key support for the refined control of the stir-frying process of Chinese medicine, and is especially suitable for the production of high-end medicinal slices with high requirements for the integrity of medicinal materials and the uniformity of efficacy.
