Description
Technical Field
[0001] This application relates to the field of fragrance processing equipment technology, specifically to an external circulation vacuum evaporator for fragrance extraction. Background Technology
[0002] In the fragrance manufacturing industry, evaporation is a key process for fragrance extraction and concentration. As market demand for higher quality and greater diversity of fragrances continues to grow, fragrance extraction technology is also constantly evolving. During the fragrance extraction process, the vacuum evaporator plays a crucial role. By reducing internal pressure and creating a negative pressure environment, it allows the fragrance solution to vaporize at temperatures far below its boiling point at atmospheric pressure. This characteristic significantly reduces the volatilization and decomposition of active ingredients caused by high temperatures, effectively ensuring product quality and yield.
[0003] Currently, commonly used evaporation technologies mainly include single-effect evaporation, multi-effect evaporation, and membrane evaporation. However, fragrances are complex, and many active ingredients are heat-sensitive and volatile. In order to ensure a certain evaporation rate, traditional evaporation technologies often require high temperature conditions during the evaporation process. This makes the active ingredients in fragrances easily decompose or volatilize under high temperature conditions, resulting in the loss of a large amount of precious fragrance ingredients, which greatly reduces product yield and increases production costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an external circulation vacuum evaporator for flavor extraction, which has the advantages of avoiding the decomposition or volatilization of heat-sensitive and volatile active ingredients in flavors, significantly reducing the loss of active ingredients in flavors during evaporation, and improving the quality and yield of the finished product, thus solving the problems mentioned in the background technology.
[0005] To achieve the above objectives, this application provides the following technical solution: an external circulation vacuum evaporator for flavor extraction, comprising a support frame, an evaporator fixedly mounted on the inner side of the support frame, a heating assembly disposed on the outer side of the evaporator, a feed pipe fixedly connected to the upper side of the evaporator, a discharge pipe fixedly connected to the bottom of the evaporator, a circulation pump disposed below the evaporator, an input end of the circulation pump fixedly connected to one end of the discharge pipe, a connecting pipe fixedly connected to the output end of the circulation pump, the end of the connecting pipe away from the output end of the circulation pump extending through the outer side of the evaporator to the interior of the evaporator, a spiral guide plate fixedly connected to the inner side of the evaporator, a vacuum pump fixedly mounted on the upper side of the evaporator, a collection tank disposed outside the evaporator, a condenser fixedly connected to the upper side of the collection tank, a connecting pipe fixedly connected to the input end of the condenser, and the end of the connecting pipe away from the input end of the condenser fixedly connected to the output end of the vacuum pump.
[0006] The above scheme, by setting up an external circulation system consisting of a circulating pump, a discharge pipe, and a connecting pipe, allows the fragrance to circulate inside and outside the evaporator, increasing the heating area and evaporation efficiency. At this time, the spiral guide plate can guide the fragrance to flow along a specific path, prolonging its residence time in the evaporator and improving the evaporation effect. Subsequently, the vacuum pump can reduce the gas pressure inside the evaporator, achieving low-temperature evaporation and avoiding the decomposition or volatilization of heat-sensitive and volatile active ingredients in the fragrance. This significantly reduces the loss of active ingredients in the fragrance during the evaporation process and improves the quality of the finished product.
[0007] Furthermore, a detection sensor is fixedly installed on the inner side of the connecting pipe, a discharge pipe is fixedly connected to the inner side of the connecting pipe, and a discharge valve is fixedly installed on the outer side of the discharge pipe. Both the detection sensor and the discharge valve are electrically connected to an external controller.
[0008] Through the above scheme, the detection sensor can monitor the steam composition in real time. When a specific component is detected to be below the standard value, the external controller controls the discharge valve to open and discharge the non-compliant material through the discharge pipe, thus ensuring the quality of the discharged product.
[0009] Furthermore, a baffle is fixedly installed at the bottom end of the spiral guide plate, and the top of the spiral guide plate is open.
[0010] The above solution prevents the fragrance from flowing directly out of the bottom by setting a baffle at the bottom of the spiral guide plate. The top opening design facilitates the fragrance to rise along the spiral path, further extending the flow path in the evaporator and making the evaporation more complete.
[0011] Furthermore, a pressure sensor is fixedly connected to the inside of the evaporator, and a temperature sensor is fixedly connected to the inside of the evaporator. Both the pressure sensor and the temperature sensor are electrically connected to an external controller.
[0012] The above solution allows for real-time monitoring of the pressure and temperature inside the evaporator by installing pressure and temperature sensors. The data is then fed back to an external controller, enabling operators to adjust equipment operating parameters according to actual conditions and ensuring a stable and safe evaporation process.
[0013] Furthermore, a filter screen is fixedly connected to the inner side of the feed pipe.
[0014] The above-mentioned filter screen can filter out impurities in the fragrance, preventing impurities from entering the evaporator and affecting the evaporation effect and product quality.
[0015] Furthermore, a flow regulating valve is fixedly installed on the outside of the feed pipe, and a metering pump is fixedly installed on the outside of the feed pipe.
[0016] The above scheme allows for the adjustment of the flavor feed flow rate via a flow regulating valve and precise control of the feed amount via a metering pump, ensuring the stability and accuracy of the flavor feed during the evaporation process, which is beneficial for improving product quality and production efficiency.
[0017] Furthermore, the heating assembly includes a mounting frame fixedly connected to the outside of the evaporator, a heating tube fixedly mounted on the inner side of the mounting frame, a heater fixedly embedded on the outer side of the mounting frame, the input end of the heater fixedly connected to the outer side of the heating tube, and heat insulation cotton filled on the inner side of the mounting frame.
[0018] Through the above scheme, the heating tube can heat the evaporator, the heater provides energy to the heating tube, and the insulation cotton can reduce heat loss and improve energy utilization efficiency.
[0019] Furthermore, the heating tube is spiral-shaped, and its outer side is attached to the outer side of the evaporator.
[0020] With the above solution, the spiral heating tube is attached to the outside of the evaporator, which increases the contact area with the evaporator, making the heating more uniform and efficient, and further improving the evaporation effect.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This external circulation vacuum evaporator for flavor extraction uses an external circulation system consisting of a circulation pump, a discharge pipe, and a connecting pipe. This system allows the flavor to circulate inside and outside the evaporator, increasing the heating area and evaporation efficiency. A spiral guide plate guides the flavor along a specific path, extending its residence time within the evaporator and enhancing the evaporation effect. The vacuum pump then reduces the pressure inside the evaporator, achieving low-temperature evaporation and preventing the decomposition or volatilization of heat-sensitive and volatile active ingredients in the flavor. This significantly reduces the loss of active ingredients during evaporation. Simultaneously, a filter removes impurities from the flavor, preventing them from entering the evaporator and affecting the evaporation effect and product quality, further improving the quality of the finished product.

A heating tube 302 is fixedly installed on the inner side of the mounting frame 301, and a heater 303 is fixedly embedded on the outer side of the mounting frame 301. The input end of the heater 303 is fixedly connected to the outer side of the heating tube 302. The inner side of the mounting frame 301 is filled with heat insulation cotton 304. The heating tube 302 can heat the evaporator 2, and the heater 303 provides energy to the heating tube 302. The heat insulation cotton 304 can reduce heat loss and improve energy utilization efficiency. The heating tube 302 is spiral-shaped, and its outer side is attached to the outer side of the evaporator 2. The spiral-shaped heating tube 302 attached to the outer side of the evaporator 2 increases the contact area with the evaporator 2, making the heating more uniform and efficient, and further improving the evaporation effect.
[0026] Please see Figure 1 , Figure 2 and Figure 3An inlet pipe 4 is fixedly connected to the upper side of the evaporator 2, and an outlet pipe 5 is fixedly connected to the bottom of the evaporator 2. A circulation pump 6 is installed below the evaporator 2. The input end of the circulation pump 6 is fixedly connected to one end of the outlet pipe 5, and the output end of the circulation pump 6 is fixedly connected to a connecting pipe 7. The end of the connecting pipe 7 away from the output end of the circulation pump 6 extends through the outside of the evaporator 2 and into the inside of the evaporator 2. The circulation pump 6, the outlet pipe 5, and the connecting pipe 7 form an external circulation system, which allows the fragrance to circulate inside and outside the evaporator 2, increasing the heating area and evaporation efficiency. A spiral guide plate 8 is fixedly connected to the inner side of the evaporator 2, and a vacuum pump 9 is fixedly installed on the upper side of the evaporator 2.

[0027] Please see Figure 1 and Figure 3 An external collection tank 10 is provided for the evaporator 2. A condenser 11 is fixedly connected to the upper side of the collection tank 10. A connecting pipe 12 is fixedly connected to the input end of the condenser 11. The end of the connecting pipe 12 away from the input end of the condenser 11 is fixedly connected to the output end of the vacuum pump 9.

A discharge valve 15 is fixedly installed outside the discharge pipe 14. Both the detection sensor 13 and the discharge valve 15 are electrically connected to an external controller. The above-mentioned detection... The sensor 13 can monitor the steam composition in real time. When a specific component is detected to be below the standard value, the external controller controls the discharge valve 15 to open and discharge the non-compliant material through the discharge pipe 14 to ensure the quality of the discharged product. A baffle is fixedly installed at the bottom of the spiral guide plate 8, and the top of the spiral guide plate 8 is open. By setting the baffle at the bottom of the spiral guide plate 8, the fragrance can be prevented from flowing directly from the bottom. The open design at the top facilitates the fragrance to rise along the spiral path, further extending the flow path in the evaporator 2 and making the evaporation more complete.
[0028] Please see Figure 2 and Figure 5A pressure sensor 16 and a temperature sensor 17 are fixedly connected to the inner side of the evaporator 2. Both the pressure sensor 16 and the temperature sensor 17 are electrically connected to an external controller. By setting the pressure sensor 16 and the temperature sensor 17, the pressure and temperature inside the evaporator 2 can be monitored in real time, and the data can be fed back to the external controller. This allows the operator to adjust the equipment operating parameters according to the actual situation, ensuring the stable and safe operation of the evaporation process.

The filter screen 18 can filter out impurities in the fragrance, preventing impurities from entering the evaporator 2 and affecting the evaporation effect and product quality. A flow regulating valve 19 and a metering pump 20 are fixedly installed on the outer side of the feed pipe 4. The flow regulating valve 19 can adjust the fragrance feed flow rate, and the metering pump 20 can accurately control the feed amount, ensuring the stability and accuracy of the fragrance feed during the evaporation process, which is beneficial to improving product quality and production efficiency.
[0029] This embodiment of an external circulation vacuum evaporator for fragrance extraction uses an external circulation system consisting of a circulation pump 6, a discharge pipe 5, and a connecting pipe 7. This system allows the fragrance to circulate inside and outside the evaporation tank 2, increasing the heating area and evaporation efficiency. The spiral guide plate 8 guides the fragrance along a specific path, extending its residence time in the evaporation tank 2 and improving the evaporation effect. The vacuum pump 9 then reduces the pressure inside the evaporation tank 2, achieving low-temperature evaporation and preventing the decomposition or volatilization of heat-sensitive and volatile active ingredients in the fragrance. This significantly reduces the loss of active ingredients during evaporation. Simultaneously, the filter screen 18 filters out impurities in the fragrance, preventing them from entering the evaporation tank 2 and affecting the evaporation effect and product quality, further improving the quality of the finished product.
[0030] The working principle of the above embodiment is as follows: First, the feed flow rate and feed amount of the fragrance are controlled by the feed pipe 4, the flow regulating valve 19 and the metering pump 20. After impurities are filtered by the filter screen 18, the fragrance enters the evaporator 2. Then, the heater 303 in the heating assembly 3 provides energy to the spiral heating tube 302 to uniformly heat the evaporator 2. At the same time, the vacuum pump 9 reduces the air pressure in the evaporator 2 to form a vacuum environment and achieve low-temperature evaporation. At this time, the raw material is sucked in by the circulation pump 6 and the fragrance at the bottom of the evaporator 2 is extracted through the discharge pipe 5 and the connecting pipe 7 and sent back to the spiral guide plate 8 in the evaporator 2. Under its guidance, the fragrance can be made to follow the spiral path. The vapor rises, prolonging the residence time and forming an external circulation, increasing the heating and evaporation area. The vapor generated by evaporation is then drawn into the connecting pipe 12 by the vacuum pump 9 and enters the condenser 11 through the connecting pipe 12. After condensation, it flows into the collection tank 10. During this process, the pressure sensor 16 and temperature sensor 17 monitor the pressure and temperature inside the evaporator 2 in real time and provide feedback to the external controller for parameter adjustment. At the same time, the detection sensor 13 monitors the composition of the finished product mixed vapor in the connecting pipe 12. When the standard is not met, the control discharge valve 15 is opened, and the unqualified material is discharged through the discharge pipe 14, thereby achieving a highly efficient and precise fragrance extraction and evaporation process.
