Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical manufacturing, and in particular to a temperature-controlled stirring and frying machine for medicinal herbs. Background Technology

[0002] The temperature-controlled stirring and frying machine is a special equipment for processing traditional Chinese medicine. Its core functions are precise temperature control and uniform stirring to ensure the quality of the processed medicinal materials. During operation, after the medicinal materials are placed in the container, the heating system heats the materials, the stirring system stirs them, and the temperature control system maintains the set temperature until the frying is completed. Compared with traditional manual frying, it can reduce labor intensity, solve the problems of uneven heating and difficulty in temperature control, and improve efficiency and efficacy. It is widely used in Chinese medicine and health product factories, hospitals, and the food industry.

[0003] Existing patent number CN216318887U discloses a drum-type herb-frying machine with uniform heating and adjustable temperature. Addressing the problem that existing herb-frying machines cannot perform a secondary turning of the herbs during frying, resulting in uneven heating and causing the herbs to become either too dry or too wet, thus reducing the quality and value of the herbs, the following solution is proposed: A PLC controller can be used to control the sequential operation of a first motor and a second motor. When the PLC controller controls the first motor, its output shaft drives a fixed third rotating rod to rotate and stir the herbs inside the frying drum. When the PLC controller controls the second motor, its output shaft drives the components in the frying assembly, where a turning plate in the frying assembly allows for a secondary turning of the herbs.

[0004] Problems identified in existing technologies: Most existing stir-frying drums and stirring components have fixed connections or complex disassembly structures. After stir-frying, herbal residues easily adhere to the gaps in the stirring components and the inner wall of the stir-frying drum. Cleaning requires a lot of time, and long-term residues may breed bacteria, affecting the hygiene and safety of subsequent herbal materials. Utility Model Content

[0005] To address the above technical problems, this utility model provides a temperature-controlled stirring and frying herb machine, characterized by comprising a frame support structure, a temperature-controlled heating structure, and a frying drum structure. The temperature-controlled heating structure is disposed above the frame support structure, and the frame support structure and the temperature-controlled heating structure are connected by bolts and nuts. The temperature-controlled heating structure and the frying drum structure are connected by bolts and nuts.

[0006] The frame support structure consists of a main frame, shock-absorbing pads, and a control panel. The main frame is a cuboid frame structure. Shock-absorbing pads are provided at the four bottom corners of the main frame. The shock-absorbing pads are fixedly connected to the main frame by bolts and nuts. The control panel is located on one side of the main frame and is connected to the main frame by bolts and nuts.

[0007] The temperature-controlled heating structure consists of a heating cover, segmented heating tubes, a temperature sensor, and a temperature control module. The heating cover is a semi-cylindrical hollow structure that wraps around the outside of the inner cylinder of the stir-frying herb. The segmented heating tubes are evenly distributed on the inner wall of the heating cover. The temperature sensor is located at the feed inlet end of the inner cylinder of the stir-frying herb and is connected to the inner cylinder of the stir-frying herb by bolts and nuts. The temperature control module is located inside the control panel of the frame support structure and is electrically connected to the segmented heating tubes and the temperature sensor by wires.

[0008] The herbal frying cylinder structure consists of an inner frying cylinder, a motor, a stirring shaft, spiral stirring blades, an elastic scraper, a heat-insulating cover, and a discharge hopper. The inner frying cylinder is located inside the heating cover of the temperature-controlled heating structure and is connected to the heating cover via a detachable flange. The motor is located outside the inner frying cylinder, and its output end is connected to the stirring shaft. Spiral stirring blades and an elastic scraper are located on the outside of the stirring shaft, and are connected to the stirring shaft, spiral stirring blades, and elastic scraper via bolts and nuts. A heat-insulating cover and a discharge hopper are located on one side of the inner frying cylinder, and are connected to the heat-insulating cover via hinges. The inner frying cylinder and the discharge hopper are connected via bolts and nuts. The elastic scraper is an arc-shaped sheet structure made of food-grade silicone rubber, which is characterized by high temperature resistance, good elasticity, and resistance to deformation. The arc of the elastic scraper is consistent with the arc of the inner wall of the stir-frying cylinder. After installation, the edge of the scraper fits tightly against the inner wall of the stir-frying cylinder, which can scrape off the medicinal residues attached to the cylinder wall in real time during the stirring process and avoid the generation of dead corners in the stirring. The heat preservation cover is equipped with sealing rings around its perimeter to ensure the airtightness of the stir-frying cylinder after the heat preservation cover is closed.

[0009] The beneficial effects of this utility model are as follows: This invention improves the frame support structure, which consists of a main frame, shock-absorbing feet, and a control panel. During the frying process, the motor operation and the turning of the herbs inside the frying cylinder generate vibrations. The shock-absorbing feet absorb this vibration energy through their elasticity, preventing direct transmission of vibration to the ground and significantly reducing noise during operation. Simultaneously, the vibration buffering reduces rigid collisions between the frame and components, lowering the probability of loose bolts and component wear, extending equipment lifespan, and reducing maintenance frequency. The control panel is integrated into one side of the main frame and houses a temperature control module, offering advantages in both operational efficiency and temperature control accuracy. In two aspects: Workers no longer need to operate individual components separately, such as adjusting heating elements or checking temperatures. They can directly set the temperature, start stirring, and monitor the operating status through the control panel, reducing operational steps and improving the efficiency of frying herbs. This is especially suitable for batch processing of medicinal materials. The temperature data of the inner frying cylinder collected by the temperature sensor is transmitted to the temperature control module on the control panel. Workers can read the temperature value intuitively through the panel. If the temperature deviates from the set range, the temperature control module can quickly provide feedback and adjust the power of the segmented heating elements to prevent the herbs from being carbonized due to local overheating or insufficient heating, thus ensuring the stability of the frying quality.

[0010] This invention improves the temperature control heating structure, which consists of a heating cover, segmented heating tubes, a temperature sensor, and a temperature control module. The semi-cylindrical structure of the heating cover can concentrate and confine the heat generated by the heating tubes within the closed space between the inner cylinder of the medicine-frying plant and the heating cover, preventing the heat from spreading to the surrounding environment and ensuring that the heat is preferentially applied to the inner cylinder of the medicine-frying plant, thereby improving heating efficiency.

[0011] This invention improves the structure of the stir-frying cylinder, which consists of an inner cylinder, a motor, a stirring shaft, spiral stirring blades, an elastic scraper, a heat-insulating cover, and a discharge hopper. The inner cylinder works in conjunction with the heating cover of the temperature-controlled heating structure to fully receive the heat from the heating tube. The motor drives the spiral stirring blades to rotate through the stirring shaft, causing the herbs to tumble continuously inside the inner cylinder, thus achieving uniform heating and ensuring the quality of the stir-frying process. This prevents some herbs from being undercooked or overcooked. The arc of the elastic scraper matches the arc of the inner wall of the inner cylinder. After installation, the edge of the scraper fits tightly against the inner wall of the inner cylinder, allowing it to scrape off herb residues adhering to the cylinder wall in real time during stirring, avoiding dead corners and ensuring the cleanliness of the inner cylinder. It also helps to stir-fry the herbs evenly. The discharge hopper makes discharging more convenient. Attached Figure Description

[0015] This utility model provides a temperature-controlled stirring and frying herb machine, characterized in that the frame support structure consists of a main frame 1, shock-absorbing feet 2, and a control panel 3; the temperature-controlled heating structure consists of a heating cover 4, segmented heating tubes, a temperature sensor 6, and a temperature control module; and the frying cylinder structure consists of an inner frying cylinder 8, a motor 9, a stirring shaft 10, spiral stirring blades 11, an elastic scraper 12, a heat-insulating cover 13, and a discharge hopper 15. The main frame 1 is a cuboid frame structure. Shock-absorbing pads 2 are installed at the four corners of the bottom of the main frame 1. The shock-absorbing pads 2 are fixedly connected to the main frame 1 by bolts and nuts. The control panel 3 is located on one side of the main frame 1 and is connected to the main frame 1 by bolts and nuts. The heating cover 4 is a semi-cylindrical hollow structure that wraps around the outside of the inner cylinder 8 for frying herbs. The segmented heating tubes are evenly distributed on the inner wall of the heating cover 4. The temperature sensor 6 is located at the feed inlet end of the inner cylinder 8 and is connected to the inner cylinder 8 by bolts and nuts. The temperature control module is located inside the control panel 3 of the frame support structure and is electrically connected to the segmented heating tubes and the temperature sensor 6 via wires. The inner cylinder 8 for frying herbs is located inside the heating cover 4 of the temperature-controlled heating structure. The inner cylinder 8 and the heating cover 4 are connected by a detachable flange. The motor is located outside the inner cylinder 8. The output end of the motor is connected to the stirring shaft 10. The outer side of the stirring shaft 10 is provided with a spiral stirring blade 11 and an elastic scraper 12. The stirring shaft 10 is connected to the spiral stirring blade 11 and the elastic scraper 12 by bolts and nuts. One side of the inner cylinder 8 is provided with a heat preservation cover 13 and a discharge hopper 15. The inner cylinder 8 and the heat preservation cover 13 are connected by a hinge. The inner cylinder 8 and the discharge hopper 15 are connected by bolts and nuts.

[0016] Example 2

[0017] When using this utility model, the preliminary preparation work of the equipment must be completed first. First, check the stability of the frame support structure and confirm that the shock-absorbing pads 2 at the four corners of the bottom of the main frame 1 are not offset and the bolts are not loose, so as to ensure that the equipment can effectively buffer vibration during operation. Then, start the equipment self-test program through the control panel 3 on one side of the main frame 1 to check whether the circuit connection between the temperature control module and the segmented heating tube and temperature sensor 6 is normal. If the panel displays no fault code, the frying operation process can be entered.

[0018] Open the heat-insulating cover 13 on one side of the inner cylinder 8, which is connected by a hinge. Pour the herbs to be fried into the inner cylinder 8 through the feed inlet. According to the type of herbs and processing requirements, set the target temperature and stirring speed on the control panel 3. For example, when frying Atractylodes macrocephala, the temperature can be set to 120-140℃ and the stirring speed can be adjusted to medium speed. After setting, close the heat-insulating cover 13. The sealing ring around it will tightly fit the port of the inner cylinder 8 to prevent heat loss and herb dust from overflowing. Then start the heating and stirring functions. In the temperature-controlled heating structure, the semi-cylindrical heating cover 4 will concentrate the heat generated by the segmented heating tubes and wrap it around the outside of the inner cylinder 8. The temperature sensor 6 collects the temperature data at the feed inlet of the inner cylinder 8 in real time and transmits the signal to the temperature control module in the control panel 3. If the temperature is lower than the set value, the temperature control module will automatically increase the power of the heating tubes. If the temperature is too high, the power will be reduced to always maintain a stable temperature inside the cylinder.

[0019] When the motor 9 is running, it will drive the stirring shaft 10 and the outer spiral stirring blades 11 and elastic scraper 12 to rotate synchronously. The spiral stirring blades 11 can push the medicinal materials to roll axially in the inner drum 8, ensuring that the medicinal materials are in full contact with heat. The arc-shaped elastic scraper 12 will fit tightly against the inner wall of the inner drum 8, and scrape off the medicinal material residues attached to the drum wall in real time during the rotation. This not only avoids the carbonization of the residues from affecting the quality of the subsequent medicinal materials, but also eliminates the dead corners of stirring, ensuring that all medicinal materials are heated evenly. After the frying is completed, the heating function is turned off first. After the temperature drops to a safe range, the heat preservation cover 13 is opened, and the staff uses tools to smoothly discharge the medicinal materials through the discharge hopper 15.

[0020] During the equipment cleaning phase, since the inner cylinder 8 for frying herbs is connected to the heating cover 4 via a detachable flange, the bolts at the flange can be unscrewed to remove the inner cylinder 8 from the heating cover 4. Then, the fixing bolts of the spiral stirring blade 11 and the elastic scraper 12 on the stirring shaft 10 can be removed to thoroughly rinse all components. The cleaning is convenient and leaves no dead corners, effectively avoiding the problem of bacteria growing from long-term residues and ensuring the hygiene and safety of subsequent medicinal materials. Throughout the entire use process, the shock-absorbing foot pads 2 continuously absorb equipment vibration, significantly reducing operating noise. The integrated operation of the control panel 3 also simplifies the process, taking into account both the quality of frying herbs and the efficiency of operation.

The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
