[0002] This application claims priority to Chinese patent application No. 202311084306.5 filed on August 28, 2023, and cites the contents disclosed in the above patent application as part of this application. Technical Field

[0003] The present application relates to the technical field of volatile oil extraction, and in particular to an adjustable condensing device for light volatile oil. Background Art

[0004] Volatile oils, also known as essential oils, fragrance oils, or aromatic oils, are primarily derived from aromatic Chinese medicinal herbs, particularly those from the Asteraceae (artemisia argyi, atractylodes, and white atractylodes), Apiaceae (angelica, fennel, and bupleurum), Rutaceae (citrus and zanthoxylum), Lamiaceae (mint and perilla), and Zingiberaceae (such as ginger and zedoary). They are primarily composed of chemical molecules such as terpenes, aldehydes, esters, and alcohols. Most plant essential oils possess a variety of biological activities, including anti-inflammatory, antibacterial, anti-allergic, antioxidant, enzyme inhibitory, and anti-tumor properties. They are widely used in fragrances, the food industry, pharmaceuticals, medical treatments, cosmetics, and agricultural pest control. Pharmacological experiments have shown that volatile oils from Chinese medicinal herbs exhibit anti-inflammatory, anti-allergic, antimicrobial, anti-mutagenic, anti-cancer, anthelmintic, enzyme inhibitory, and central nervous system and respiratory effects. The content of volatile oils in Chinese medicinal materials generally ranges from 0.12% to 10%.

[0005] Condensers are often used in chemical or pharmaceutical preparations, especially in the manufacture of volatile oils. Condensers condense high-temperature gaseous oil-water mixtures into liquid oil-water mixtures through heat exchange, which are then separated in subsequent processes.

[0006] However, the current condenser has the following defects: the length of the condenser tube inside the condenser is fixed and long, and the temperature of the oil-water mixture is low when it leaves the condenser tube, causing the viscosity of the volatile oil in the oil-water mixture to increase.

[0007] Summary of the Invention

[0008] Based on this, the purpose of this application is to provide an adjustable condensing device for light volatile oil, so as to at least solve the problem in the prior art that the viscosity of the volatile oil in the oil-water mixture increases because the length of the condenser tube inside the condenser is fixed and long, and the temperature of the oil-water mixture is low when it leaves the condenser tube.

[0009] According to an embodiment of the present application, an adjustable condensing device for light volatile oil includes a condenser and a valve pipe assembly embedded in the top of the condenser;

[0010] The condenser includes a condensation pipeline disposed internally, a valve pipe assembly disposed adjacent to the condensation pipeline, and the condenser further includes a coolant inlet disposed at the bottom of the condenser and extending outward from the condenser body, and a coolant outlet disposed at the top of the condenser and extending outward from a side of the coolant inlet;

[0011] The valve pipe assembly includes a short pipe embedded in the top of the condenser and located inside the condensing pipe, a plurality of short-circuit guide ports extending from the short pipe along the axis of the condensing pipe, and a valve core movably arranged in the short pipe for controlling the opening and closing of the plurality of short-circuit guide ports;

[0012] The condensation pipeline includes a feed port extending from the top of the condenser to the outside of the condenser body, a discharge port extending from the bottom of the condenser to the outside of the condenser body, a condenser pipe arranged between the feed port and the discharge port for communication, and a short-circuit interface extending from the inner side of the condenser pipe toward the valve pipe assembly and connected to multiple short-circuit guide ports. The outer shape of the condenser pipe is a spiral design of a multi-layer condenser pipe, and each layer of spiral pipe is horizontally inclined downward so that the oil-water mixture in the condenser pipe that flows into the short-circuit pipe along the short-circuit interface can be directly discharged along the discharge port.

[0013] Furthermore, a water retaining portion is provided on each layer of the condensing tubes so that the condensed water is collected on the side of the water retaining portion on each layer of the condensing tubes where the level is higher.

[0014] Furthermore, the water retaining portion has an inverted V-shaped design.

[0015] Furthermore, the short-circuit interface is provided at the bottom of the higher side of the water retaining portion.

[0016] Furthermore, it also includes a lifting rod arranged near the condenser.

[0017] Furthermore, the output end of the lifting rod is connected to the valve core, so that the valve core can slide along its track in the short connecting pipe.

[0018] Furthermore, a plurality of water retaining parts are provided on the condensing pipe, and the bottom end of the short pipe is connected to the discharge port.

[0019] Compared with the prior art: This application proposes an adjustable condensing device for light volatile oil. First, the preparation personnel can inject the coolant into the condenser through the coolant inlet and fill the condenser to pre-cool the condenser tube arranged inside it. Then, the feed port is connected to the external raw material discharge port, so that the high-temperature gaseous oil-water mixture can be passed into the condenser tube along the feed port for condensation treatment and converted into a liquid oil-water mixture. Specifically, in the actual volatile oil extraction process, a large amount of water vapor is first generated before the high-temperature gaseous oil-water mixture enters the condensation pipeline, and is preferentially introduced into the condenser tube through the feed port. The water vapor will condense in the tube to form condensed water and pass through the condenser tube, but because the water retaining part provided on each layer of the condenser tube will affect the cooling The condensed water is blocked so that the condensed water is gathered on the side with a higher level of the water retaining part. When the water gathered at the top water retaining part exceeds the highest horizontal position of the water retaining part, the water will flow along the top condenser tube to the next layer of condenser tubes, and gather again at the water retaining part set at the lower condenser tube until condensed water is gathered at the water retaining part set at each layer of condenser tubes. After that, the gaseous oil-water mixture enters the condenser tube and condenses to form a liquid oil-water mixture. Since the condenser tube is covered by the gathered water near the water retaining part, the liquid oil-water mixture will adhere to the water surface and flow along the condenser tube, reducing the contact between the oil-water mixture and the condenser tube and increasing the yield of volatile oil. The structure is simple and reliable, the operating energy consumption is low, and it can significantly reduce 15% to 80% of light volatile oil. The yield is lost due to adhesion. In addition, since the volatile oil in the liquid oil-water mixture will continue to drop as the temperature decreases and the viscosity increases, the liquid oil-water mixture needs to be discharged in time. Therefore, the preparation personnel can adjust the height of the valve core between the multiple layers of condensers upwards to open the short-circuit guide port at the condenser layer with the best condensation effect of the liquid oil-water mixture, so that the liquid oil-water mixture can flow along the short-circuit guide port at the condenser layer with the best current effect into the short-circuit guide port connected to it and flow into the discharge port for discharge, thereby achieving the purpose of adjusting the condenser path and avoiding the increase in viscosity when the volatile oil in the liquid oil-water mixture continues to condense. It is understandable that the higher the valve core rises, the smaller the subsequent discharge of liquid oil-water mixture. Due to the short contact time with the coolant, the temperature of the volatile oil in the liquid oil-water mixture is relatively high and the viscosity is low, provided that the gaseous oil-water mixture is completely condensed to a liquid oil-water mixture. This effectively solves the problem that the oil-water mixture in the current condenser is fixed and long in length due to the internal condenser tube, which causes the oil-water mixture to condense for a long time in the condenser tube and the temperature drops to a low level. Since the viscosity of the volatile oil is prone to increase at low temperatures, the oil-water mixture formed by condensation is in full contact with the tube wall throughout the entire process in the condenser tube, and when passing through a longer condenser tube, the viscosity of the volatile oil increases and the adhesion to the inner wall of the condenser tube becomes more serious, making it impossible for the volatile oil to enter the subsequent oil-water mixture separation and collection, seriously affecting the yield of volatile oil of traditional Chinese medicine.

The drawings illustrate several embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Example

[0038] Please refer to Figures 1 to 6, which show an adjustable condensing device for light volatile oil in an embodiment of the present application, including a condenser 1 and a valve pipe assembly 3 embedded in the top of the condenser 1. The condenser 1 includes a condensation pipeline 4 arranged inside. The valve pipe assembly 3 is arranged near the condensation pipeline 4. The valve pipe assembly 3 includes a short pipe 31 embedded in the top of the condenser 1 and located on the inside of the condensation pipeline 4, a plurality of short-circuit guide ports 33 extending from the short pipe 31 in the axial direction of the condensation pipeline 4, and a valve core 32 movably arranged in the short pipe 31 for controlling the opening and closing of the plurality of short-circuit guide ports 33. The condensation pipeline 4 includes a valve core 32 extending from the top of the condenser 1 to the condensation pipeline 4. The inlet 41 extends from the outside of the condenser body 1, the outlet 42 extends from the bottom of the condenser 1 to the outside of the condenser body 1, the condenser pipe 43 is arranged between the inlet 41 and the outlet 42 for communication, and the inner side of the condenser pipe 43 extends toward the valve pipe assembly 3 to connect with multiple short-circuit guide ports 33. The condenser pipe 43 has a spiral design of a multi-layer condenser pipe, and each layer of spiral pipes is horizontally inclined downward. The bottom end of the short-circuit pipe 31 is connected to the outlet 42, so that the oil-water mixture in the condenser pipe 43 that flows into the short-circuit pipe 31 along the short-circuit interface 45 can be directly discharged along the outlet 42.

[0039] During specific implementation, the preparation personnel may first inject the coolant into the condenser 1 through the coolant inlet 11 and fill the condenser 1 to pre-cool the condenser tube 43 provided therein. In some optional embodiments, liquid pumps may be installed at the coolant inlet 11 and the coolant outlet 12 respectively, and the liquid pump pipelines may be connected to an external refrigeration device to form a coolant pumping circulation in the condenser 1. The feed port 41 may then be connected to the external raw material outlet so that the high-temperature gaseous oil-water mixture may be passed along the feed port 41 into the condenser tube 43 for condensation treatment to form the final liquid oil-water mixture and then be discharged through the discharge port 42. Furthermore, the condenser 1 also includes a coolant inlet 11 extending outward from the bottom and a coolant outlet 12 extending outward from the top away from the coolant inlet 11. The condenser tube 43 is spirally designed and has a total of eleven layers. In some optional embodiments of the present application, the number of layers of the condenser tube 43 is not limited.

[0040] For example, assuming a spiral condenser 43 with eleven layers, as shown in FIG1 , the number of layers can be adjusted based on the desired condensation effect to meet the condensation requirements for the volatile oil. By the time the gaseous oil-water mixture reaches the seventh layer of condenser 43, it has completely liquefied into a liquid oil-water mixture. If the recondensation path is too long, the temperature of the volatile oil will drop further, increasing its viscosity and causing it to adhere to the inner wall of the condenser. In this regard, in the embodiment of the present application, the preparation personnel can pull the valve core 32 upward to disengage the valve core 32 from the short-circuit guide port 33 at the bottom eleventh to seventh layer condenser tubes 43 in sequence, so that the short-circuit guide port 33 flows directly along the short-circuit pipe 31 to the discharge port 42 for discharge, and at the same time, the liquid oil-water mixture originally retained at the eleventh to seventh layer condenser tubes 43 can flow along the short-circuit guide port 33 into the short-circuit pipe 31 to be discharged at the discharge port 42, shortening the path of the oil-water mixture through the condenser tube 43, achieving the effect of adjustable liquid guide path of the condenser tube 43, and at the same time reducing the contact area between the volatile oil in the oil-water mixture and the tube wall, thereby improving the yield of the volatile oil.

[0041] In some optional embodiments of the present application, a temperature sensor may be provided at the discharge port 42 to obtain the temperature of the currently discharged liquid oil-water mixture and observe the current viscosity. When the temperature sensor detects that the temperature of the discharged oil-water mixture is too low, the current valve core 32 may be further moved to the condenser tube 43 at the level with the best effect. It is understood that the higher the valve core 32 is raised, the shorter the contact time of the subsequently discharged liquid oil-water mixture with the coolant, and the temperature of the volatile oil in the liquid oil-water mixture is relatively high and the viscosity is low, provided that the gaseous oil-water mixture is completely condensed into a liquid oil-water mixture.

[0042] In addition, to facilitate the regulation of the valve core 32, a lifting rod 2 can be set on the side close to the condenser 1, and the output end of the lifting rod 2 is connected to the valve core 32 so that the valve core 32 can slide along its trajectory in the short pipe 31. In some optional embodiments of the present application, the lifting rod 2 can be an electric lifting rod and a hydraulic lifting rod. The preparation personnel can electrically connect the lifting rod 2 to the temperature sensor set at the discharge port 42, wherein the electrical connection can be a wireless connection and a wired connection, and the wireless connection method includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, zigbee, and the wired connection method includes but is not limited to a USB line connecting the temperature sensor and the lifting rod 2. The specific control can obtain the temperature information of the liquid oil-water mixture fed back at the discharge port 42 through the temperature sensor, and analyze the temperature information through the controller in the temperature sensor. The controller also stores initial control data. For example, when the temperature of the liquid oil-water mixture is ten degrees Celsius, the corresponding height of the valve core 32 is located at the open position of the short-circuit guide port 33 at the ninth layer of the condenser 43; when the temperature of the liquid oil-water mixture is twenty degrees Celsius, the corresponding height of the valve core 32 is located at the open position of the short-circuit guide port 33 at the seventh layer of the condenser 43. The viscosity of the corresponding liquid oil-water mixture at the above different temperatures is also different. The controller can be an MCU (Microcontroller Unit; microcontroller unit) chip, which controls the lifting height of the lifting rod 2 through the MCU chip and drives the valve core 32 to adjust the height in the short-circuit pipe 31. The preparation personnel can judge the viscosity of the liquid oil-water mixture according to its temperature and enter the control parameters through the controller so that the lifting rod 2 can drive the valve core 32 to adjust the use height in real time in the short-circuit pipe 31 according to the feedback temperature, so as to ensure the quality and acquisition amount of the liquid oil mixture subsequently discharged along the discharge port 42, which is convenient for the preparation personnel to operate and use.

[0043] Furthermore, in this embodiment, each layer of condenser tube 43 is provided with an upwardly protruding water retaining portion 44 so that the condensed water is gathered on the higher side of the water retaining portion 44. The water retaining portion 44 has an inverted V-shaped design, and the short-circuit interface 45 is opened at the bottom of the higher side of the water retaining portion 44.

[0044] Specifically, in the actual volatile oil extraction process, water vapor evaporates before volatile oil. Therefore, before the high-temperature gaseous oil-water mixture enters the condensation line 4, a large amount of water vapor will be introduced into the condenser 43 through the feed port 41. The water vapor will condense in the tube to form condensed water and pass through the condenser 43. However, the water retaining portion 44 provided on each layer of the condenser 43 will block the condensed water, so that the condensed water is gathered on the side with a higher level of the water retaining portion 44. When the water gathered at the top water retaining portion 44 exceeds the highest level of the water retaining portion 44, the water will flow down to the next layer of condenser 43 and gather again at the water retaining portion 44 provided on the lower condenser 43 until condensed water is gathered at the water retaining portion 44 provided on each layer of the condenser 43. As shown in FIG2 of the specification, the shaded portion at the top condenser 43 is the gathered condensed water. At the same time, when the gaseous oil-water mixture enters the condenser tube 43 and condenses to form a liquid oil-water mixture, since the condenser tube 43 is covered by the collected water near the water retaining portion 44, the liquid oil-water mixture will adhere to the water surface and flow along the condenser tube 43, so that the condensed liquid oil-water mixture flows on the water surface in the condenser tube. By preventing the viscosity of the volatile oil in the oil-water mixture from increasing rapidly due to the low temperature and reducing the contact between the light volatile oil in the oil-water mixture and the condenser tube, the loss of light volatile oil due to adhesion to the inner wall of the condenser tube is reduced, thereby improving the yield of volatile oil. The water retaining portion 44 provided at the condenser tube 43 can significantly reduce the yield loss of light volatile oil due to adhesion by 15% to 80%.

[0045] Specifically, the water retaining portion 44 is calculated to reduce the adhesion of volatile oil as follows: Assuming the inner radius of the condenser is R (constant), the coordinate system shown in FIG4 is established, thereby obtaining the formula: 0<y<2R, shaded cross-sectional area: but According to the above formula, the cross section of the condenser tube during condensation of the present application is obtained as shown in FIG5 , wherein H is the height of the condensed water, h2 is the height of the oil-water mixture, and the cross-sectional area of ​​the oil-water mixture is: The contact circumference of the oil-water mixture and the condenser is:

[0046] Furthermore, as shown in FIG6 , the cross section of the condenser tube during condensation in a conventional condenser is shown, where h1 is the height of the oil-water mixture and the cross-sectional area of ​​the oil-water mixture is shown in FIG6 . The contact circumference of the oil-water mixture and the condenser is Solving the system of equations yields: From this, we can get the percentage of volatile oil loss due to adhesion reduction Taking other factors into consideration and combining them with the above formula can significantly reduce the loss of light volatile oil due to adhesion by 15% to 80%.

[0047] It is further explained that the volatile oils in the oil-water mixture in the present application are all light volatile oils, and their specific characteristic is that their density is less than that of water. Therefore, they have the effect of the liquid oil-water mixture formed by condensation flowing on the water surface in the condenser as mentioned above, and the subsequent liquid oil-water mixture can also be merged with the water collected at the water retaining portion 44 and circulate normally along the condenser 43 toward the discharge port 42. It should be noted that when the temperature gradually decreases, the light volatile oil in the liquid oil-water mixture formed by condensation will be more easily adhered to the inner wall of the condenser 43 due to the increase in viscosity, resulting in the loss of volatile oil in the liquid oil-water mixture and reducing the yield of the light volatile oil.

[0048] In summary, first, the preparation personnel can inject the coolant into the condenser 1 through the coolant inlet 11 and fill the condenser 1 to pre-cool the condenser tube 43 set inside it, and then connect the feed port 41 with the external raw material discharge port, so that the high-temperature gaseous oil-water mixture can be passed into the condenser tube 43 along the feed port 41 for condensation treatment and converted into a liquid oil-water mixture. Specifically, in the actual volatile oil extraction process, a large amount of water vapor is first generated before the high-temperature gaseous oil-water mixture enters the condensation pipe 4 and is preferentially introduced into the condenser tube 43 through the feed port 41. The water vapor will condense in the tube to form condensed water and pass through the condenser tube 43, but the water retaining part 44 provided on each layer of the condenser tube 43 will block the condensed water, so that the condensed water is located on the side with a higher level of the water retaining part 44 and is gathered. When the water collected at the top water retaining part 44 exceeds the highest level of the water retaining part 44, the water will flow along the top condenser tube 43 to the next layer of condenser tube 43 and gather again at the water retaining part 44 provided on the lower condenser tube 43. The condenser 43 is provided with a water retaining portion 44 and condensed water is collected thereon. After that, the gaseous oil-water mixture enters the condenser 43 and condenses to form a liquid oil-water mixture. Since the condenser 43 is covered by the collected water near the water retaining portion 44, the liquid oil-water mixture will adhere to the water surface and flow along the condenser 43, reducing the contact between the oil-water mixture and the condenser 43, thereby improving the yield of volatile oil. The structure is simple and reliable, and the operating energy consumption is low. In addition, since the volatile oil in the liquid oil-water mixture will continue to drop as the temperature continues to drop and the viscosity will increase, the liquid oil-water mixture needs to be discharged in time. Therefore, the preparation personnel can adjust the height of the valve core 32 between the multiple layers of condenser tubes 43 upwards until the short-circuit guide port 33 of the condenser tube 43 with the best condensation effect of the liquid oil-water mixture is opened, so that the liquid oil-water mixture can flow along the short-circuit guide port 33 of the condenser tube 43 with the best current effect into the short-circuit pipe 31 connected thereto and flow into the discharge port 42 for discharge, thereby achieving the purpose of adjusting the path of the condenser tube 43.
