Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicinal material processing, in particular to low-temperature baking furnace equipment and a process for Chinese medicinal materials with high efficiency and component retention. Background Art

[0002] In the field of Chinese herbal medicine processing, baking is a critical step, and its effect is directly related to the quality and medicinal value of Chinese herbal medicines. Currently, conventional baking ovens have many problems that cannot be ignored when baking Chinese herbal medicines.

[0003] On the one hand, some conventional ovens use a hot air baking method. In this mode, because the oven environment is not completely clean, the hot air inevitably carries various air impurities. These impurities adhere to the surface of the Chinese medicinal materials during the baking process, not only contaminating the materials but also triggering chemical reactions, resulting in the destruction of the active ingredients in the materials and reducing their medicinal effects. Moreover, the intensity and temperature of the hot air are difficult to distribute evenly within the oven. In areas with strong hot air, the Chinese medicinal materials may be overheated, causing some heat-sensitive components such as volatile oils to evaporate in large quantities and destroying the structure of components such as alkaloids. In areas with weak hot air, the Chinese medicinal materials are not heated enough, and drying is inadequate, resulting in uneven overall baking results.

[0004] On the other hand, baking Chinese medicinal materials in an oven while they are still there also has drawbacks. When Chinese medicinal materials are still in the oven, their contact with heat mainly relies on thermal radiation and natural convection. However, the temperature at different locations inside the oven varies, and the distances between different parts of the Chinese medicinal materials and the heat source are different, resulting in uneven heat transfer. The parts close to the heat source may be over-dried, while the parts far from the heat source remain moist, resulting in inconsistent drying of the Chinese medicinal materials, which seriously affects their quality and subsequent storage and use. Therefore, a low-temperature baking furnace equipment and process for Chinese medicinal materials that can efficiently retain ingredients is proposed to solve the above-mentioned problems.

[0014] Preferably, there are two cleaning parts, and the other cleaning part is symmetrically installed on the other side of the top of the furnace body.

[0017] A process for low-temperature baking of traditional Chinese medicine with high efficiency and component retention, comprising the following steps:

[0018] Step 1: Preparation: Select various types of Chinese medicinal materials and classify them according to their characteristics. Load each type of Chinese medicinal material into four barrels respectively. Thread the barrel cap onto the barrel mouth to ensure a good seal. Then align the spoon-shaped insert sleeve of the barrel with the spoon-shaped insert rod and insert it. Use the opposite poles between the magnet and the suction block to fix it so that the four barrels are respectively against the inner walls of the four baking slots;

[0019] Step 2: During the baking phase, the heating plate is turned on. The heating plate heats up the metal box, and then the Chinese medicinal materials in the barrel are baked at low temperature through heat transfer. During this process, the heat dissipation holes on both sides of the furnace body wall ensure natural ventilation and heat dissipation, ensuring stable temperature inside the furnace.

[0020] Step 3: Stir-frying and cleaning are carried out simultaneously. The motor works intermittently in forward and reverse directions, driving the screw to rotate, causing the L-shaped grille to move horizontally, and then driving the metal box to move along one side of the guide rod. When the metal box moves to the left, the baking tank uses friction to cause the barrel to rotate. The barrel is squeezed into the baking tank and the position of the tank edge rises. The slider is driven up through the gasket, and the slider drives the distance sensor to rise. When the distance between the distance sensor and the detection plate changes and generates an electrical signal, the air pump is started. The air pump sucks clean air filtered by the air filter and blows it to the baking tank through the air jet pipe, cleaning the inner wall of the baking tank that moves to the left. Air jet cleaning avoids contamination of Chinese medicinal materials. When the four baking slots move to the left and are completely separated from the four barrels, the four sliders reset downward under the tension of the tension springs, driving the four barrels to abut against the eight convex strips on the same side. The convex strips move to the left with the metal box, causing the barrels to shake rapidly through the elasticity of the tension springs, shaking off the broken impurities of the outer wall of the barrel and the internal Chinese medicinal materials onto the receiving plate. When the motor drives the metal box to move to the right, the guide slope guides the adjacent barrels to roll back into the baking slot by friction. At the same time, the air pump cooperates with the cleaning work. Every time the barrel enters and leaves the corresponding baking slot, the inner wall of the baking slot will be cleaned once;

[0021] Step 4: Complete baking and discharging, continue the above baking, stir-frying and cleaning process until the Chinese medicinal materials reach the ideal degree of dryness, open the transparent door on the front of the furnace body, unscrew the barrel cover by the handle, take the baked Chinese medicinal materials out of the barrel, clean the debris and impurities on the receiving plate, and prepare for the next baking work.

The L-shaped grille 75 facilitates the impurity fragments after jet cleaning to penetrate and fall onto the receiving plate 10.

[0044] A process for low-temperature baking of traditional Chinese medicine with high efficiency and component retention, comprising the following steps:

[0045] Step 1: Preparation: Select various types of Chinese medicinal materials and classify them according to their characteristics. Load each type of Chinese medicinal material into four barrels 54 respectively. Thread the barrel cover 56 onto the barrel opening of the barrel 54 to ensure a good seal. Then, align the spoon-shaped insert sleeve 55 of the barrel 54 with the spoon-shaped insert rod 52 and insert it. Use the opposite polarity attraction between the magnet 53 and the suction block to fix it, so that the four barrels 54 respectively abut against the inner walls of the four baking slots 33;

[0046] Step 2: During the baking phase, the heating plate is activated, and the heating plate heats up the metal box 31, thereby baking the Chinese medicinal materials in the barrel 54 at a low temperature through heat transfer. During this process, the heat dissipation holes 8 on both sides of the outer wall of the furnace body 1 ensure natural ventilation and heat dissipation, ensuring a stable temperature inside the furnace;

[0047] Step 3: Stir-frying and cleaning are carried out simultaneously, and the motor 73 works intermittently in forward and reverse directions, driving the screw 74 to rotate, causing the L-shaped grille 75 to move horizontally, and then driving the metal box 31 to move along one side of the guide rod 2. When the metal box 31 moves to the left, the baking groove 33 uses friction to cause the barrel 54 to rotate, and the barrel 54 is squeezed into the baking groove 33. The groove edge position rises, and the slider 44 is driven to rise through the gasket 51, and the slider 46 drives the distance sensor 47 to rise. When the distance between the distance sensor 47 and the detection plate 48 changes and generates an electrical signal, the air pump 61 is started, and the air pump 61 sucks clean air filtered by the air filter 64 and blows it to the baking groove 33 through the air jet pipe 62, and the inner wall surface of the baking groove 33 that moves to the left is cleaned. Jet cleaning is performed to avoid contamination of the Chinese medicinal materials. When the four baking grooves 33 move to the left and are completely separated from the four barrels 54, the four sliders 44 are reset downward under the tension of the tension springs 45, driving the four barrels 54 to abut against the eight ridges 35 on the same side. The ridges 35 follow the metal box 31 to move to the left, causing the barrels 54 to shake quickly and elastically through the tension springs 45, shaking off the broken impurities of the outer wall of the barrel 54 and the internal Chinese medicinal materials onto the receiving plate 10. When the motor 73 drives the metal box 31 to move to the right, the guide slope 34 guides the adjacent barrels 54 to roll back into the baking groove 33 by friction. At the same time, the air pump 61 cooperates with the cleaning work. Every time the barrel 54 enters and leaves the corresponding baking groove 33, the inner wall of the baking groove 33 is cleaned once.

[0048] Step 4: Complete baking and discharging. Continue the above baking, stir-frying, and cleaning processes until the Chinese medicinal materials reach the ideal degree of dryness. Open the transparent furnace door on the front of the furnace body 1, unscrew the cylinder cover 56 by the handle, take the baked Chinese medicinal materials out of the barrel 54, clean the debris and impurities on the receiving plate 10, and prepare for the next baking work.

[0049] Working principle: Chinese medicinal materials can be added to four barrels 54 in multiple groups to achieve batch baking processing. The spoon-shaped socket 55 of the barrel 54 can be aligned with the spoon-shaped rod 52 to limit the insertion, and fixed by adsorption between the magnet 53 and the suction block. The heating plate causes the metal box 31 to heat up by generating heat, so that the inner wall of each baking groove 33 heats each barrel 54 by heat transfer, achieving the effect of low-temperature baking of Chinese medicinal materials. Different from the traditional technical center hot air baking technology, the heat transfer between metals will not produce air impurities to contaminate the Chinese medicinal materials, thereby improving the cleanliness of the furnace environment, and avoiding the chemical reaction caused by the heating of impurities and Chinese medicinal materials, thereby reducing the problem of medicinal effect, and efficiently retaining the Chinese medicinal ingredients.

[0050] The motor 73 works intermittently in forward and reverse rotation, driving the L-shaped grille 75 to move horizontally through the screw 74. For example, when it moves to the left, the mounting plate 76 drives the metal box 31 to limit along the guide rod 2 and move to the left. The baking groove 33 uses friction to cause the barrel 54 to rotate. When the barrel 54 is squeezed into the groove edge of the baking groove 33, the position of the barrel 54 is raised, and the slider 44 is driven to rise through the gasket 51, thereby causing the slider 46 to drive the distance sensor 47 to rise, so that the distance sensor 47 generates an electrical signal through the change in the distance between it and the detection plate 48 to start the air pump 61. The air pump 61 continues to suck air and further improves the cleanliness of the inhaled air through the air filter 64, and then blows the air along the air jet pipe 62 to the baking groove 33. Since the air jet pipe 62 is not aligned with the barrel 54, it will only spray and clean the inner wall surface of the baking groove 33 that moves to the left, avoiding further contamination of the Chinese medicinal materials.

[0051] When the four baking grooves 33 move to the left and are completely separated from the four material barrels 54, the four sliders 44 are reset downward in turn by the tension of the tension springs 45, and drive the four material barrels 54 to abut against the eight ridges 35 on the same side in turn. The ridges 35 follow the metal box 31 to move to the left, and then drive the four material barrels 54 to shake rapidly through the elasticity of the tension springs 45, further vibrating and shaking off the broken impurities of the outer wall and the internal Chinese medicinal materials of the material barrel 54 onto the receiving plate 10, thereby improving the cleaning efficiency and cleaning quality. Conversely, when the motor 73 drives the metal box 31 to move to the right, the guide slope 34 will first guide the adjacent material barrels 54 to frictionally roll and return to the baking groove 33. At the same time, the air pump 61 continues to cooperate with the cleaning work to ensure that each time the material barrel 54 enters or leaves the corresponding baking groove 33, the inner wall of the baking groove 33 will be cleaned first, thereby improving the cleanliness of the working environment, facilitating the improvement of continuous processing quality and efficiency, and reducing the pressure of manual cleaning.

10. A process for low-temperature baking of Chinese medicinal materials with high efficiency and retention of components, according to the low-temperature baking furnace equipment of Chinese medicinal materials with high efficiency and retention of components according to claims 1-9, characterized in that: The following steps are involved: Step 1: Preparation work, select a variety of different types of Chinese medicinal materials, classify them according to their characteristics, and respectively put each type of Chinese medicinal materials into four barrels (54), screw the barrel cover (56) to the barrel mouth of the barrel (54) to ensure good sealing, then align the spoon-shaped insert sleeve (55) of the barrel (54) with the spoon-shaped insert rod (52) and insert it, and use the opposite polarity attraction between the magnet (53) and the suction block to fix it, so that the four barrels (54) are respectively against the inner walls of the four baking grooves (33); Step 2: During the baking phase, the heating plate is started, and the heating plate generates heat to cause the metal box (31) to heat up, thereby baking the Chinese medicinal materials in the barrel (54) at a low temperature through heat transfer. During this process, the heat dissipation holes (8) on both sides of the outer wall of the furnace body (1) ensure natural ventilation and heat dissipation, thereby ensuring a stable temperature in the furnace. Step 3: Stir-frying and cleaning are carried out simultaneously, and the motor (73) rotates intermittently in forward and reverse directions, driving the screw (74) to rotate, causing the L-shaped grille (75) to move horizontally, and then driving the metal box (31) to move along one side of the guide rod (2). When the metal box (31) moves to the left, the baking groove (33) uses friction to cause the barrel (54) to rotate, and the barrel (54) is squeezed into the baking groove (33). The groove edge position rises, and the slider (44) is driven to rise through the gasket (51). The slider (46) drives the distance sensor (47) to rise. When the distance between the distance sensor (47) and the detection plate (48) changes and generates an electrical signal, the air pump (61) is started. The air pump (61) sucks clean air filtered by the air filter (64) and blows it to the baking groove (33) through the air jet pipe (62), and the inner wall surface of the baking groove (33) that moves to the left is cleaned. The four baking grooves (33) are moved to the left and completely separated from the four barrels (54), and the four sliders (44) are reset downwards under the tension of the tension springs (45), driving the four barrels (54) to abut against the eight ridges (35) on the same side. The ridges (35) follow the metal box (31) to move to the left, so that the barrels (54) are elastically shaken quickly by the tension springs (45), and the broken impurities of the outer wall of the barrel (54) and the internal Chinese medicinal materials are shaken off to the receiving plate (10). When the motor (73) drives the metal box (31) to move to the right, the guide slope (34) guides the adjacent barrels (54) to roll back into the baking groove (33) by friction. At the same time, the air pump (61) cooperates with the cleaning work. Each time the barrel (54) enters and leaves the corresponding baking groove (33), the inner wall of the baking groove (33) is cleaned once. Step 4: Complete baking and discharging. Continue the above baking, stir-frying and cleaning process until the Chinese medicinal materials reach the desired degree of dryness. Open the transparent door on the front of the furnace body (1), unscrew the cylinder cover (56) by the handle, take the baked Chinese medicinal materials out of the barrel (54), clean the broken materials and impurities on the receiving plate (10), and prepare for the next baking work.
