Description

Technical Field

[0001] This utility model relates to the field of plant extract concentration technology, specifically a plant extract concentration device. Background Technology

[0002] Plant extracts are mixtures of active ingredients obtained from plants through extraction, separation, and other processes. For example, green tea extract contains tea polyphenols, which have antioxidant effects; aloe vera extract contains polysaccharides, which can moisturize and soothe. They are widely used in food, health products, cosmetics, and other fields. Plant extracts are generally extracted with ethanol or water. In subsequent production, ethanol or water needs to be removed through a concentration process to meet the needs of subsequent processing. Heating evaporation concentration is the most basic and commonly used method for concentrating plant extracts. The core principle is to vaporize and separate the solvent (water or ethanol) in the extract by heating, thereby increasing the concentration of the active ingredients. This method has low equipment costs and is suitable for plant ingredients that are relatively stable to heat.

[0003] In practice, high temperatures may damage heat-sensitive components, and traditional electric heating methods do not easily ensure uniform heating of the extract, resulting in localized high temperatures that ultimately affect the effective components of the plant extract. Therefore, we propose a plant extract concentration device. Utility Model Content

[0004] The purpose of this invention is to provide a plant extract concentration device. By having a conical upper heating plate and a lower heating plate inside the concentration tank, the plant extract is drawn in a circular motion and passes through the surface of the upper and lower heating plates in sequence through the through holes, thereby obtaining a larger heating area and heating more fully and evenly. This avoids prolonged or high-temperature heating to fully heat the plant extract, which could damage heat-sensitive components and ensure the quality of the final extract, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plant extract concentration device, comprising a concentration tank, an upper heating plate, and a lower heating plate, wherein the upper and lower heating plates are both fixed inside the concentration tank, the upper heating plate is a positive cone shape located above the inverted cone shape of the lower heating plate, and through holes are uniformly opened on the surfaces of both the upper and lower heating plates; a liquid addition hopper is provided above the concentration tank, and a liquid addition pipe is connected below the liquid addition hopper, the liquid addition pipe penetrates into the concentration tank and is located above the upper heating plate, a liquid extraction pump is installed on the side surface of the concentration tank, the inlet of the liquid extraction pump is connected to the bottom of the concentration tank through the liquid extraction pipe, and the outlet of the liquid extraction pump is connected to a return pipe, the return pipe penetrates into the concentration tank and is connected to the side of the heating pipe.

[0006] By adopting the above technical solution, the plant extract is pumped and circulated through the upper and lower heating plates. When it flows through the surfaces of the upper and lower heating plates, it obtains sufficient heating area and uniform heating effect, ensuring that the plant extract is fully and evenly heated and evaporated to remove solvents such as water or ethanol, thereby achieving the purpose of concentration.

[0007] Optionally, an air pipe is provided on the top side of the concentration tank, and the air pipe is connected to the interior of the concentration tank.

[0009] Optionally, the bottom of the liquid inlet tube is located directly above the middle position of the upper heating plate.

[0010] By adopting the above technical solution, it is ensured that the plant extract falls from the middle position onto the surface of the upper heating plate and then diffuses downwards.

[0011] Optionally, a temperature sensor is installed inside the concentration tank, located at the bottom of the tank.

[0012] By adopting the above technical solution, the temperature of the liquid inside the concentration tank can be monitored in real time using a temperature sensor.

[0013] Optionally, a liquid outlet pipe is connected to the middle of the bottom of the concentration tank, and the liquid outlet pipe communicates with the interior of the concentration tank.

[0016] By adopting the above technical solution, the concentration tank is supported by multiple legs at its bottom.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: 1. The technical solution of this application is to set up a cone-shaped upper electric heating plate and a lower electric heating plate inside the concentration tank, so that the plant extract is drawn in a ring and passes through the surface of the upper and lower electric heating plates in sequence through the through hole, thereby obtaining a larger heating area and being heated more fully and evenly. This avoids prolonged or high-temperature heating in order to fully heat the plant extract, which would damage the heat-sensitive components and ensure the quality of the finished extract.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a plant extract concentration device, including a concentration tank 1, an upper heating plate 2 and a lower heating plate 3. The bottom outer ring of the concentration tank 1 is supported by a support leg 12. Multiple support legs 12 are provided, and each support leg 12 has the same length, so as to achieve stable support for the concentration tank 1.

[0022] A liquid addition hopper 4 is provided above the concentration tank 1, and a liquid addition pipe 41 is connected below the liquid addition hopper 4. The liquid addition pipe 41 extends into the interior of the concentration tank 1. When in use, the plant extract is added into the interior of the concentration tank 1 through the liquid addition hopper 4 and the liquid addition pipe 41.

[0023] The upper heating plate 2 and the lower heating plate 3 are both fixed inside the concentration tank 1. The upper heating plate 2 is a positive cone shape located above the inverted cone shape of the lower heating plate 3. Both the upper heating plate 2 and the lower heating plate 3 have uniformly opened through holes 21. The bottom of the liquid addition pipe 41 is located directly above the middle position of the upper heating plate 2. When the plant extract falls downward from the liquid addition pipe 41, it falls into the middle position of the upper heating plate 2 through the lower liquid addition pipe 41, and then diffuses and flows downward and outward, obtaining a sufficiently large heating area with the upper heating plate 2 so that the plant extract is fully and evenly heated. Afterward, the plant extract flows downward through the through holes 21 of the upper heating plate 2 and falls onto the surface of the lower heating plate 3, and then diffuses and flows downward and inward, obtaining a sufficiently large heating area with the lower heating plate 3 so that the plant extract is fully and evenly heated.

[0024] In addition, a liquid pump 5 is installed on the side surface of the concentration tank 1. The inlet of the liquid pump 5 is connected to the bottom of the concentration tank 1 through the liquid pump pipe 51, and the outlet of the liquid pump 5 is connected to the return pipe 52. The return pipe 52 passes through the concentration tank 1 and is connected to the side of the heating tube. After all the plant extracts are added, the liquid pump 5 is started again to draw the plant extract through the liquid pump pipe 51 and return it to the liquid addition pipe 41 through the return pipe 52. The plant extract can be heated continuously in the above manner to evaporate the water or ethanol in it. In order to prevent the plant extracts from contacting the lower heating plate 3, it is also necessary to ensure that the liquid level after the plant extracts are added is not greater than the bottom height of the lower heating plate 3.

[0025] Temperature sensor 13 is installed inside the concentration tank 1. Temperature sensor 13 is located at the bottom of the concentration tank 1. The upper heating plate 2, the lower heating plate 3 and temperature sensor 13 are all connected to the industrial control computer, which can monitor the liquid temperature during use and control the processing temperature of the upper heating plate 2 and the lower heating plate 3 according to the temperature.

[0026] In addition, a gas pipe 14 is provided on the top side of the concentration tank 1. The gas pipe 14 is connected to the inside of the concentration tank 1. During the heating and concentration process, the gas pipe 14 is connected to a vacuum pump or other vacuuming equipment, which helps to smoothly discharge the evaporated gas.

[0027] Finally, a liquid outlet pipe 11 is connected to the bottom center of the concentration tank 1. The liquid outlet pipe 11 is connected to the inside of the concentration tank 1. A valve is installed and closed before heating and concentration. After heating and concentration, the valve is opened so that the plant extract can be discharged from the liquid outlet pipe 11.

[0028] In use, the temperature sensor 13, upper heating plate 2, lower heating plate 3, and liquid pump 5 are all connected to the industrial control computer. A valve is installed on the liquid outlet pipe 11 and kept sealed. First, the upper heating plate 2 and lower heating plate 3 are activated and heated to the set threshold temperature. Then, the plant extract to be concentrated is slowly added from the liquid addition hopper 4. The plant extract falls through the lower liquid addition pipe 41 to the middle position of the upper heating plate 2, and then diffuses and flows downward and outward, obtaining a sufficiently large heating area with the upper heating plate 2 to ensure that the plant extract is heated fully and evenly. The plant extract flows downward through the through hole 21 of the upper heating plate 2 to the surface of the lower heating plate 3, and then diffuses and flows downward and inward, obtaining a sufficiently large heating area with the lower heating plate 3. The plant extract is heated thoroughly and evenly. It then flows downwards through the through-hole 21 of the lower heating plate 3 into the concentration tank 1. The liquid level after adding the plant extract must not exceed the bottom height of the lower heating plate 3 to avoid contact. The pump 5 is then activated to extract the plant extract through the extraction pipe 51 and returns it to the addition pipe 41 through the return pipe 52. This heating process can be repeated continuously to evaporate water or ethanol. To ensure the smooth removal of evaporated gases, a vacuum pump or similar device can be connected to the gas pipe 14. During concentration, the temperature sensor 13 monitors the liquid temperature. After concentration, the operation of the upper heating plate 2, lower heating plate 3, and pump 5 is stopped. The valve on the outlet pipe 11 is then opened to discharge the concentrated plant extract.
