Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing, specifically to a single-effect concentrator device for concentrating ginkgo biloba esters. Background Technology

[0002] Traditional single-effect concentrators have several shortcomings in the concentration production of ginkgo biloba esters. Firstly, the cooling system typically uses only a single cooling medium, which has limited effectiveness in condensing volatile solvents during concentration, resulting in significant solvent loss, increased production costs, and resource waste. Secondly, the liquid discharge process is mostly carried out at atmospheric pressure, making it susceptible to external air intrusion that can disrupt the vacuum environment inside the concentration tank, causing temperature fluctuations and damaging the active ingredients in the ginkgo biloba esters, such as ginkgo flavonoids and terpene lactones, thus reducing product quality. Thirdly, the steam condensate drainage system often uses manual steam traps, which are inherently slow and difficult to precisely control, leading to steam waste and unstable concentration temperatures, affecting concentration efficiency and batch-to-batch product consistency. Therefore, there is an urgent need to improve existing single-effect concentrators to meet the demands for efficient and stable concentration production of ginkgo biloba esters.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0016] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Example 1

[0018] Figure 1 This is a schematic diagram of the structure of this utility model.

[0019] like Figure 1 As shown, a single-effect concentrator device for concentrating ginkgo ketone esters includes: a concentration tank 100, a triple cooling system 200, a negative pressure liquid outlet system 300, a receiving tank 400, and an automatic drainage system 500. The top of the concentration tank 100 is connected to the triple cooling system 200, the negative pressure liquid outlet system 300 is connected to the concentration tank 100, the triple cooling system 200 is connected to the receiving tank 400 through the negative pressure liquid outlet system 300, and the automatic drainage system 500 is connected to the concentration tank 100.

[0020] The triple cooling system 200 includes: a condenser 210, a first-stage circulating cooling water cooling device 220, a second-stage chilled water cooling device 230, a collection tank 240, and a third-stage collection tank chilled water cooling device 250. The top two sides of the condenser 210 are connected to the concentration tank 100 and the negative pressure liquid outlet system 300, respectively. The first-stage circulating cooling water cooling device 220 is arranged around the outside of the condenser 210. The second-stage chilled water cooling device 230 is arranged in the condensation channel of the condenser 210. The third-stage collection tank chilled water cooling device 250 is arranged around the outside of the collection tank 240.

[0021] The negative pressure liquid discharge system 300 includes: a negative pressure liquid discharge pump 310, a negative pressure liquid discharge pressure sensor 320, and a vacuum pump 330. The negative pressure liquid discharge pump 310 is located between the collection tank 240 and the receiving tank 400, the negative pressure liquid discharge pressure sensor 320 is located inside the concentration tank 100, and the vacuum pump 330 is connected to the concentration tank 100.

[0022] The automatic drainage system 500 includes: a pneumatic shut-off valve 510, a DCS control system 520, and a steam pressure sensor 530. The pneumatic shut-off valve 510 is located on the drainage pipeline of the steam condensate of the concentrator 100. The DCS control system 520 is connected to the pneumatic shut-off valve 510 and the steam pressure sensor 530. The steam pressure sensor 530 is located on the steam pipeline of the concentrator 100.

[0023] The working principle of this invention is as follows: During the concentration of ginkgo ketone esters, the concentrator is activated, and the ginkgo ketone ester extract is injected into the concentration tank 100. At this time, the triple cooling system 200 starts working. The first-stage circulating cooling water cooling device 220 initially cools the outside of the condenser 210 to reduce the temperature of the volatile solvent vapor. After the solvent vapor enters the condenser 210, the second-stage chilled water cooling device 230 deeply cools it, causing most of it to condense into liquid. The condensed solvent enters the collection tank 240, and the third-stage chilled water cooling device 250 keeps the collection tank 240 warm to ensure that the solvent is fully condensed.

[0024] Throughout the concentration process, vacuum pump 330 continuously operates to maintain a negative pressure ≤ -0.07 MPa within concentration tank 100. Negative pressure outlet pressure sensor 320 monitors the vacuum level within the tank in real time and feeds the data back to the control system. When the condensate reaches a certain volume, the control system automatically activates negative pressure outlet pump 310 based on the data from negative pressure outlet pressure sensor 320, delivering the condensate to receiving tank 400 under vacuum, ensuring pressure fluctuations ≤ ±0.005 MPa to prevent outside air from entering and affecting the concentration process.

[0025] In the automatic drainage system 500, the DCS control system 520 monitors the data from the steam pressure sensor 530 on the steam pipeline to determine the condensate situation in the concentration tank 100. When the set drainage conditions are met, the pneumatic shut-off valve 510 is automatically opened to discharge the condensate, while preventing steam leakage, ensuring stable steam pressure, maintaining the concentration temperature fluctuation within ±1℃, and ensuring that the concentration process is carried out efficiently and stably.

[0026] Ginkgo biloba extract is a key active ingredient in Ginkgo biloba leaf extract, exhibiting significant pharmacological activity. However, it is temperature-sensitive, easily degraded, and the organic solvents used in the extraction process are costly and subject to stringent environmental regulations. The innovation of this invention lies in its triple-gradient cooling system tailored to the characteristics of ginkgo biloba extract: A triple-gradient cooling system with decreasing temperature gradients is designed to address the physical properties of the extraction solvent. A third-stage cooling device is added to the collection tank to address the volatile nature of the solvent during concentration. The temperature parameters for each cooling stage can be adjusted to match the condensation characteristics of the extraction solvent, which is less effective in traditional single-stage cooling systems where only one parameter is used. Therefore, compared to traditional concentration devices, this invention can retain up to 9.6% more solvent per concentration cycle, achieving efficient solvent retention and recycling, reducing the amount of new solvent input, lowering production costs, and reducing solvent recovery and treatment costs, aligning with green production principles.

[0027] Secondly, the negative pressure dispensing system protects the activity of ginkgo biloba extract. This fully negative pressure dispensing process is specifically designed for the heat-sensitive characteristics of ginkgo biloba extract. It achieves high-precision pressure control of ±0.005MPa during the concentration process, and a closed-loop control system maintains a stable vacuum environment during dispensing. The negative pressure dispensing pump, in conjunction with a vacuum pump, maintains a stable vacuum in the concentration tank. The condensate is dispensed under vacuum, preventing external air from entering and disrupting the vacuum environment. This lowers the boiling point of the extract and prevents high-temperature fluctuations during concentration from damaging the active ingredients of ginkgo biloba extract. Low-temperature concentration effectively preserves the activity of the medicinal components, improving product quality. Simultaneously, the vacuum environment reduces solvent evaporation and further improves solvent recovery. This significantly lowers the concentration temperature of ginkgo biloba extract, effectively protecting its molecular structure from thermal damage; reduces quality instability caused by temperature fluctuations during concentration; ensures batch-to-batch product quality consistency; and improves the clinical efficacy reliability of ginkgo biloba extract preparations.

[0028] Finally, the dedicated automatic steam trap system for Ginkgo biloba extract concentration utilizes a high-precision steam control system developed specifically for the temperature sensitivity of Ginkgo biloba extract concentration. Based on the optimal concentration parameters for Ginkgo biloba extract, the customized DCS control system facilitates easy control. Combined with the characteristics of the Ginkgo biloba extract concentration process, the response time of the pneumatic valves is optimized. The automatic shut-off valve works in conjunction with the DCS control system to monitor steam pressure in real time and automatically control valve opening and closing. Compared to traditional manual steam traps, this increases steam utilization from approximately 80% to over 95%, reduces steam consumption, avoids steam pressure fluctuations caused by manual operation delays, ensures stable concentration temperature (fluctuation ≤ ±1℃), and guarantees concentration efficiency and batch consistency.

[0029] Compared with traditional technologies, this invention achieves efficient solvent retention, stable production process, and optimized steam energy efficiency through the innovative design of a triple cooling system, a negative pressure liquid outlet system, and an automatic hydrophobic system, thereby improving the efficiency and product quality of ginkgo ketone ester concentration.

[0030] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
