Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid concentration tools, specifically to an extract concentration device. Background Technology
[0002] Extract concentration technology is an indispensable key process in many industries such as pharmaceuticals, chemicals, and food. Its core lies in removing water or other solvents from the extract through physical or chemical methods, thereby increasing the concentration of the target component and facilitating subsequent processing, storage, and use.
[0003] When concentrating extracts, a corresponding extract concentration device is usually used. There are many types of extract concentration devices on the market. Most extract concentration devices use a temperature-controlled electric heater to achieve the heating operation. During the heating process, stirring is carried out to promote the discharge of steam, thereby achieving the concentration effect.
[0004] However, in the use of such extract concentration devices, the vent is generally directly connected to the outside, causing hot steam to be discharged directly. Since the hot steam contains a significant amount of heat, this direct discharge results in the waste of that heat, which is detrimental to improving the utilization rate of thermal energy. Therefore, we propose an extract concentration device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5 This utility model provides a technical solution: an extract concentration device, including a concentration cylinder 1, with a temperature-controlled electric heater 13 fixedly installed on the outside of the concentration cylinder 1, so that the extract can be concentrated in a uniform and controllable temperature environment, which effectively improves the concentration efficiency and product quality, while avoiding component loss or denaturation caused by excessively high or low temperatures.
[0029] Specifically, a top cover 14 is fixedly installed on the top of the concentrator 1, an exhaust hood 2 is fixedly installed on the top cover 14, and a fan 20 is fixedly installed on the inner wall of the exhaust hood 2, ensuring that the steam components generated during the concentration process can be effectively collected and discharged.
[0030] Specifically, an exhaust pipe 21 is fixedly installed at the end of the exhaust hood 2, a curved pipe 22 is fixedly installed at the end of the exhaust pipe 21, a moisture absorption cylinder 24 is fixedly installed at the top of the curved pipe 22, a mesh cylinder 27 is slidably connected inside the moisture absorption cylinder 24, and a molecular sieve 28 is provided inside the mesh cylinder 27 to realize the moisture absorption operation using the molecular sieve 28. In addition, the mesh cylinder 27 can be removed outward, making it easier to replace the molecular sieve 28 inside the mesh cylinder 27.
[0031] Specifically, a sealing cap 29 is fixedly installed on the top of the moisture absorption cylinder 24 for sealing operation and reducing leakage; a dry gas return pipe 25 is fixedly installed on the top cylinder of the moisture absorption cylinder 24, and the end of the dry gas return pipe 25 extends into the concentration cylinder 1, realizing the recycling of the dry gas after dehumidification. This not only reduces energy waste, but also improves concentration efficiency and reduces production costs. At the same time, the return of dry gas also helps the gas in the concentration cylinder to circulate and distribute evenly, further improving the concentration effect.
[0032] In this embodiment, the cross-section of the curved pipe 22 is U-shaped, and a vertically arranged drain pipe 23 is fixedly installed at the bottom center of the curved pipe 22. A valve 231 is fixedly installed on the drain pipe 23 so that when there is water inside the curved pipe 22, the valve 231 can be opened to allow the water to be discharged from the drain pipe 23.
[0033] Specifically, the mesh cylinder 27 has a mesh-like cylindrical structure for normal air permeation operation. At the same time, the mesh cylinder 27 can also support the molecular sieve 28.
[0034] Furthermore, a support ring 26 is fixedly installed on the top cylinder of the moisture-absorbing cylinder 24, and the sealing top cover 29 is fixedly installed on the upper surface of the support ring 26 by multiple fastening screws, which facilitates the fixing, installation and disassembly and opening operations; a sealing ring 261 is embedded in the support ring 26, and the sealing top cover 29 abuts against the upper surface of the sealing ring 261 to improve the sealing effect and reduce leakage.
[0035] In addition, a conical cylinder 10 is fixedly installed at the bottom of the concentrator 1, and a discharge pipe 11 is fixedly installed at the bottom of the conical cylinder 10. A discharge valve 12 is fixedly installed on the discharge pipe 11. The conical cylinder 10 is funnel-shaped, and the plane of the inner wall of the conical cylinder 10 is inclined downward at 45° to 60°, so that the material can flow to the discharge pipe 11 more quickly, improving the discharge speed and efficiency. At the same time, it also reduces the residence time of the material in the conical cylinder 10, avoiding component loss or deterioration caused by long residence time.
[0036] It is worth noting that a feed pipe 15 is fixedly installed on the top cover 14, and a feed valve 151 is fixedly installed on the feed pipe 15 to realize the feeding operation. At the same time, when the feed valve 151 is closed, it can block the feed pipe 15.
[0037] It is worth noting that a stirring motor 16 is fixedly installed at the center of the upper surface of the top cover 14, and a stirring shaft 161 is fixedly installed at the end of the output shaft of the stirring motor 16. A stirring blade 162 is fixedly installed on the stirring shaft 161. The stirring blade 162 is located inside the concentration cylinder 1, which realizes the full stirring and mixing of the material inside the concentration cylinder 1, and improves the uniformity and stability of the concentration process.
[0038] Finally, it should be noted that the components involved in this utility model, such as the fan 20, the temperature-controlled electric heater 13, and the stirring motor 16, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.
[0039] When using the extract concentration device of this utility model, firstly, open the feed valve 151 and accurately feed the extract into the concentration cylinder 1 through the feed pipe 15. After the material is added, close the feed valve 151. Then, start the temperature-controlled electric heater 13 to concentrate the extract in the concentration cylinder 1 in a uniform and controllable temperature environment. At the same time, the stirring motor 16 drives the stirring shaft 161 and stirring blades 162 to rotate, fully stirring and mixing the material in the concentration cylinder 1 to ensure the uniformity and stability of the concentration process.
[0040] During the concentration process, the generated steam components are effectively collected by the exhaust hood 2 and forced out by the fan 20, entering the moisture absorption cylinder 24 through the exhaust pipe 21 and the curved pipe 22. Inside the moisture absorption cylinder 24, the molecular sieve 28 supported by the mesh cylinder 27 absorbs moisture from the steam, removing the water.
[0041] The dehumidified high-temperature dry gas flows back to the concentration cylinder 1 through the dry gas return pipe 25, realizing energy recovery and utilization, and at the same time promoting the discharge of hot steam in the concentration cylinder 1.
[0042] When water accumulates inside the curved tube 22, valve 231 can be opened to allow the water to drain from the drain pipe 23. After concentration is completed, the temperature-controlled electric heater 13 and the stirring motor 16 are turned off, and the discharge valve 12 is opened. The material in the conical cylinder 10 flows quickly to the discharge pipe 11 under the action of gravity, achieving rapid discharge. After discharge is completed, the discharge valve 12 is closed, and the mesh cylinder 27 can be removed and the molecular sieve 28 replaced as needed.
