Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine fermentation, specifically a humidity control device for traditional Chinese medicine fermentation. Background Technology

[0002] Polygonum multiflorum, a traditional Chinese medicine with a long history and wide application value, undergoes fermentation. The fermentation process aims to increase the content of active ingredients in the herb through the action of microorganisms, while reducing or transforming certain components harmful to the human body, thereby enhancing efficacy and safety. During the fermentation of Polygonum multiflorum, humidity not only directly affects the activity, growth, and reproduction of microorganisms, but also indirectly affects the internal moisture balance and chemical reaction rate of the herb. Excessive humidity can lead to an overly moist surface, promoting the growth of harmful microorganisms and increasing the risk of spoilage. Furthermore, excessive humidity can affect the internal moisture distribution, resulting in uneven fermentation and hindering the extraction and transformation of medicinal properties. Conversely, if the humidity is too low, the herb may lose necessary moisture due to dryness, leading to reduced microbial activity and hindering the fermentation process, thus affecting the quality and efficacy of the herb.

[0003] According to published patent 202123225931.6, a fermentation chamber for precise humidity control, it includes a foaming chamber body and a door, which are connected to form a fermentation chamber. A circulating air duct is provided inside the fermentation chamber. The chamber is characterized by further including an electric heating element with an evaporation plate mounted on it. A nozzle is mounted on the evaporation plate to intermittently spray water onto the evaporation plate. This fermentation chamber for precise humidity control, by intermittently spraying water onto the evaporation plate with the nozzle, can precisely control the amount of water used for evaporation, thereby precisely controlling the humidity inside the fermentation chamber. Furthermore, the evaporation plate on the electric heating element can both heat and maintain the temperature inside the fermentation chamber, and also control the humidity inside the fermentation chamber after the water is sprayed, achieving precise control of both temperature and humidity inside the fermentation chamber.

[0004] However, in practice, traditional humidity control devices for Chinese herbal medicine fermentation humidify by spraying water directly onto the surface of an evaporation plate, relying on evaporation to increase humidity. In this process, the water doesn't evaporate instantly but undergoes a continuous, gradual evaporation. Even when the ambient humidity reaches the preset standard, the evaporation plate may still be generating steam. Even if the heating function is turned off at this point, the residual heat on the plate surface will continue to heat the remaining moisture for a short period, causing further evaporation and affecting the accuracy of humidity control. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a humidity control device for traditional Chinese medicine fermentation. This addresses the problem that current traditional humidity control devices for traditional Chinese medicine fermentation use water directly sprayed onto the surface of an evaporation plate to increase humidity through evaporation. However, in this humidification process, the water does not evaporate completely on the surface of the evaporation plate instantly, but rather undergoes a continuous and gradual evaporation process. When the ambient humidity reaches the preset standard, the evaporation plate may still be generating steam. Even if the heating function of the evaporation plate is turned off at this time, the residual heat on the surface of the evaporation plate will continue to heat the remaining water for a short period of time, causing the water to continue to evaporate. This leads to the technical problem of affecting the accuracy of humidity control.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a humidity control device for traditional Chinese medicine fermentation is designed, including a fermentation cylinder, a water tank is provided at the top of the fermentation cylinder, the water tank is connected to the fermentation cylinder by a support rod, a dual-shaft motor is installed at the top of the fermentation cylinder, and agitation components are provided at both the upper and lower ends of the dual-shaft motor, an air pump is connected to the bottom of the front end of the fermentation cylinder, one end of a flexible hose is connected to the front end of the air pump, the other end of the flexible hose is connected to the fermentation cylinder, and a feed pipe is connected to the top of the fermentation cylinder, and a first pipe cover is detachably connected to the top of the feed pipe.

[0007] Preferably, the agitation assembly includes a first rotating rod, a second rotating rod, agitating blades, and agitating rods.

[0008] Preferably, the first rotating rod is connected to the top of the dual-axis motor, the top of the first rotating rod extends into the water tank, and a plurality of stirring rods are installed at the end of the first rotating rod located in the water tank.

[0009] Preferably, the second rotating rod is connected to the bottom of the dual-shaft motor, the bottom of the second rotating rod extends into the fermentation cylinder, and multiple stirring blades are installed at one end of the second rotating rod located inside the fermentation cylinder.

[0010] Preferably, the top and side of the water tank are connected to one end of a water pipe, and the other end of the water pipe is detachably connected to a second pipe cover. An electric heating tube is installed at the bottom of the second pipe cover located at the top, and the bottom of the electric heating tube passes through the water pipe and extends into a circular groove opened at the top of the first rotating rod.

[0011] Preferably, the stirring rod has an installation groove at one end near the first rotating rod, and a metal heat-conducting block is installed inside the installation groove, with the metal heat-conducting block in contact with the surface of the first rotating rod.

[0012] Preferably, a control host is installed on the side of the fermentation cylinder, humidity sensors are installed on both sides of the top of the fermentation cylinder, and a support base plate is fixed at the bottom, with wheels installed at the four corners of the bottom of the support base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This invention combines a dual-shaft motor, a stirring assembly, and a vacuum pump. The dual-shaft motor drives the stirring blades and rods to rotate simultaneously, achieving not only uniform stirring of the fermenting material within the fermentation tank to promote fermentation, but also ensuring even heat distribution in the water tank. This allows hot water from the bottom of the tank to be carried to the top, resulting in a more uniform water temperature and promoting steam generation. Simultaneously, an electric heating element heats the water in the tank, and the vacuum pump draws the heated water into the fermentation tank, achieving precise humidification of the fermentation environment. Because the water tank and fermentation tank are separated, the problem of uncontrolled humidity within the fermentation tank caused by continuously heated water generating steam is avoided. Furthermore, the device is equipped with a humidity sensor inside the tank, allowing operators to precisely adjust the humidity conditions within the fermentation tank based on real-time humidity data monitored by the sensor.

[0015] 2. This utility model combines an electric heating tube, a circular groove, and a metal heat-conducting block. The electric heating tube is directly inserted into the circular groove at the top of the first rotating rod. During the rotation of the first rotating rod, the electric heating tube can effectively heat the first rotating rod. Since the stirring rod is equipped with a metal heat-conducting block that is in close contact with the surface of the first rotating rod, the heat on the first rotating rod can be quickly transferred to different positions in the water tank through the rotation of the stirring rod, realizing uniform heating of the water and thus improving the efficiency of water vapor generation.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A humidity control device for traditional Chinese medicine fermentation, see [link to example]. Figures 1 to 3 The system includes a fermentation cylinder 2, with a water tank 203 at the top. The water tank 203 is connected to the fermentation cylinder 2 via a support rod 103. A dual-shaft motor 202 is installed at the top of the fermentation cylinder 2, with stirring components at both ends. A vacuum pump 204 is connected to the bottom front end of the fermentation cylinder 2, with one end of a flexible hose 205 connected to the front end of the vacuum pump 204. The other end of the flexible hose 205 is connected to the fermentation cylinder 2. A feed pipe 101 is connected to the top of the fermentation cylinder 2, and a first pipe cover 102 is detachably connected to the top of the feed pipe 101. First, the dual-shaft motor 202 is turned on, driving the first rotating rod 209 and the second rotating rod 200. Simultaneously, the first rotating rod 209 is connected to the stirring rod 210, and the second rotating rod 211 is connected to the stirring blade 212. Therefore, when the rotating rods rotate, the stirring rod 210 and the stirring blade 212 also rotate. The rotation of the stirring blade 212 achieves uniform stirring of the fermented material in the fermentation tank 2, which helps in the exchange of substances and the release of gases during the fermentation process, thereby promoting fermentation. At the same time, the rotation of the stirring rod 210 ensures uniform heat distribution of the water in the water tank 203. Because the stirring rod 210 rotates in the water tank 203, it can bring the hot water at the bottom of the water tank 203 to the top, making the water temperature more uniform and conducive to the generation of water vapor. During the rotation of the rotating rod, the electric heating element 208 can be turned on. Located inside the water tank 203, the electric heating element 208 generates heat when powered on, heating the water in the tank 203. Through the heating effect of the electric heating element 208, the water temperature gradually rises. When it reaches a certain level, the water begins to produce steam. Once enough steam has been generated in the water tank 203, the vacuum pump 204 is turned on. The vacuum pump 204 draws the steam into the fermentation cylinder 2 through the hose 205, increasing the humidity inside the fermentation cylinder 2 and achieving precise humidification of the fermentation environment. The water tank 203 and the fermentation cylinder 2 are separated. The water can be continuously heated without producing excessive water vapor, which directly enters the fermentation cylinder 2. This avoids the problem of uncontrolled humidity inside the fermentation cylinder 2 caused by the continuous generation of water vapor from the heated water, ensuring the stability of the fermentation process. A humidity sensor 213 is installed inside the cylinder, which can monitor the humidity data inside the fermentation cylinder 2 in real time. Based on the humidity data provided by the sensor, the staff can precisely adjust the humidity conditions inside the fermentation cylinder 2 by adjusting the heating power of the electric heating tube 208 and the air extraction volume of the air pump 204 to meet the needs of different fermentation processes. After fermentation is completed, the fermented material can be discharged from the discharge port (not shown in the figure) at the bottom of the fermentation cylinder 2.

[0022] For details, see Figure 2The stirring assembly includes a first rotating rod 209, a second rotating rod 211, a stirring blade 212, and a stirring rod 210.

[0023] Further, see Figure 2 The first rotating rod 209 is connected to the top of the dual-axis motor 202. The top of the first rotating rod 209 extends into the water tank 203, and a plurality of stirring rods 210 are installed at one end of the first rotating rod 209 located in the water tank 203.

[0024] It is worth noting that, see Figure 2 The second rotating rod 211 is connected to the bottom of the dual-shaft motor 202. The bottom of the second rotating rod 211 extends into the fermentation cylinder 2. Multiple stirring blades 212 are installed at one end of the second rotating rod 211 located inside the fermentation cylinder 2.

[0025] It is worth noting that, see Figure 1 The top and side of the water tank 203 are connected to one end of the water pipe 206. The other end of the water pipe 206 is detachably connected to the second pipe cover 207. The bottom of the second pipe cover 207 located at the top is equipped with an electric heating tube 208, and the bottom of the electric heating tube 208 passes through the water pipe 206 and extends into the circular groove 214 opened at the top of the first rotating rod 209.

[0026] It is worth mentioning that, see Figure 3 A mounting groove 215 is provided at one end of the stirring rod 210 near the first rotating rod 209. A metal heat-conducting block 201 is installed inside the mounting groove 215. The metal heat-conducting block 201 is in contact with the surface of the first rotating rod 209. The heating element 208 is directly inserted into the circular groove 214 at the top of the first rotating rod 209, so that the heating element 208 can directly transfer heat to the first rotating rod 209 after startup. When the dual-axis motor 202 starts and drives the first rotating rod 209 to rotate, the heating element 208 simultaneously begins to heat the first rotating rod 209. Heat can be transferred from the heating element 208 to the first rotating rod 209. The unit is equipped with a metal heat-conducting block 201 that is in close contact with the surface of the first rotating rod 209. When the first rotating rod 209 rotates, the heat on its surface is transferred to the stirring rod 210 through the metal heat-conducting block 201, ensuring that the heat can be efficiently transferred from the first rotating rod 209 to the stirring rod 210. During the rotation of the stirring rod 210, the heat on its surface is carried to different positions in the water tank 203. Due to the rotation of the stirring rod 210, the water in the water tank 203 can be heated evenly, avoiding local overheating or uneven temperature. This uniform heating method improves the heating efficiency of the water, allowing water vapor to be generated more quickly.

[0027] It is worth emphasizing that, see Figure 1The fermentation cylinder 2 is equipped with a control host 104 on its side. Humidity sensors 213 are installed on both sides of the top of the fermentation cylinder 2. A support base plate 1 is fixed at its bottom. A rotating wheel 105 is installed at each of the four corners of the bottom of the support base plate 1.

[0028] It should be noted that, in order to accurately control the heating temperature, the heating element 208 is connected to a temperature controller. The temperature controller monitors the temperature of the heating element 208 and automatically adjusts its heating power according to preset adjustment data, thereby achieving precise control of the water temperature in the water tank 203. When the water temperature reaches the set value, the temperature controller automatically cuts off the power to the heating element 208 to prevent the water temperature from becoming too high; when the water temperature is lower than the set value, the temperature controller restarts the heating element 208 to ensure that the water temperature is always maintained within a suitable range. The temperature controller model is Deli DL336102, which features high precision, stability, and reliability, and is suitable for temperature control needs in various situations.

[0029] When using a humidity control device for traditional Chinese medicine fermentation, firstly, the dual-shaft motor 202 is turned on. This motor drives the first rotating rod 209 and the second rotating rod 211 to rotate simultaneously. The first rotating rod 209 is connected to the stirring rod 210, and the second rotating rod 211 is connected to the stirring blade 212. Therefore, when the rotating rods rotate, the stirring rod 210 and the stirring blade 212 also rotate. The rotation of the stirring blade 212 achieves uniform stirring of the fermented material in the fermentation cylinder 2, which helps with the exchange of substances and the release of gases during the fermentation process, thereby promoting fermentation. At the same time, the rotation of the stirring rod 210 ensures uniform heat distribution of the water in the water tank 203. Because the stirring rod 210 rotates in the water tank 203, it can bring the hot water at the bottom of the water tank 203 to the top. The rotating rod rotates to ensure a more uniform water temperature, which is conducive to the generation of water vapor. During rotation, the heating element 208, located inside the water tank 203, can be activated. When powered on, the heating element 208 generates heat, heating the water in the tank 203. Through the heating effect of the heating element 208, the water temperature gradually rises. When a certain temperature is reached, the water begins to generate water vapor. Once sufficient water vapor has been generated in the tank 203, the vacuum pump 204 is activated. The vacuum pump 204 draws the water vapor into the fermentation cylinder 2 through the hose 205, increasing the humidity within the fermentation cylinder 2 and achieving precise humidification of the fermentation environment. The water tank 203 and the fermentation cylinder 2 are separated, allowing the water in the tank 203 to be continuously heated without... Excessive water vapor will be generated and directly enter the fermentation cylinder 2, avoiding the problem of uncontrolled humidity inside the fermentation cylinder 2 caused by the continuous generation of water vapor from the continuously heated water, thus ensuring the stability of the fermentation process. A humidity sensor 213 is installed inside the cylinder to monitor the humidity data inside the fermentation cylinder 2 in real time. Based on the humidity data provided by the sensor, the operator can precisely adjust the humidity conditions inside the fermentation cylinder 2 by adjusting the heating power of the electric heating tube 208 and the air extraction volume of the vacuum pump 204 to meet the needs of different fermentation processes. After fermentation is completed, the fermented material can be discharged from the discharge port (not shown in the figure) at the bottom of the fermentation cylinder 2. The electric heating tube 208 is directly inserted into the circular groove 214 at the top of the first rotating rod 209, so that the electric heating tube 208 is activated. The heat can then be directly transferred to the first rotating rod 209. When the dual-axis motor 202 starts and drives the first rotating rod 209 to rotate, the heating element 208 simultaneously begins to heat the first rotating rod 209. Heat can be transferred from the heating element 208 to the first rotating rod 209. The stirring rod 210 has a metal heat-conducting block 201 that is in close contact with the surface of the first rotating rod 209. When the first rotating rod 209 rotates, the heat on its surface is transferred to the stirring rod 210 through the metal heat-conducting block 201, ensuring that heat can be efficiently transferred from the first rotating rod 209 to the stirring rod 210. During the rotation of the stirring rod 210, the heat on its surface is carried to different positions in the water tank 203. Due to the rotational movement of the stirring rod 210,The water in tank 203 is heated evenly, avoiding localized overheating or uneven temperature distribution. This uniform heating method improves the heating efficiency of the water, allowing steam to be generated more quickly.
