Description

Technical Field

[0001] This utility model relates to the field of herbal plant processing technology, and in particular to a concentration device for extracting herbal plants. Background Technology

[0002] In the field of herbal plant extraction, the concentration process is a crucial step in improving the quality and value of extracts, and it is widely used in various industries such as pharmaceuticals, food, and cosmetics. Currently, with the increasing demand for natural herbal products, higher requirements are being placed on concentration equipment used for herbal plant extraction.

[0003] Traditional herbal extract concentration techniques, such as multi-effect evaporation and ethanol precipitation, have many drawbacks. During the concentration process of the decoction, a large number of water-soluble impurities, such as starch, protein, mucilage, tannins, and pigments, are concentrated along with the extract and are difficult to remove effectively, severely affecting the purity of the final extract. Prolonged thermal concentration processes can easily lead to the decomposition or inactivation of heat-sensitive active ingredients, resulting in loss of active ingredients and reduced yield. For example, some flavonoids and terpenes with special medicinal value become less stable and their activity decreases significantly at high temperatures. Ethanol precipitation has limited effectiveness in removing soluble macromolecular impurities, and under certain conditions, precipitated impurities may re-flocculate, causing turbidity or precipitation in the product, greatly affecting the quality and appearance of oral liquids, granules, and ointments.

[0004] When existing technical solutions are used,

[0005] (1) The extract has poor fluidity in the tank and it is difficult to achieve uniform heating by natural convection alone, resulting in low concentration efficiency. Furthermore, local high temperature can easily cause the decomposition and inactivation of heat-sensitive active ingredients, affecting product quality. The equipment is prone to leaving viscous extract during the concentration process. The residue will not only affect the subsequent concentration effect, but may also breed bacteria.

[0006] (2) The lack of an effective filtration structure means that impurities in the extract, such as plant residues and undissolved particles, cannot be fully intercepted before entering the concentration stage. These impurities may not only clog the pipeline and affect the stability of equipment operation, but also mix into the concentrated product, reducing the purity of the product.

[0007] To address the above problems, this utility model provides a concentration device for herbal plant extraction. Utility Model Content

[0008] The purpose of this invention is to solve the problems of uneven heating of the extract, low concentration efficiency, difficult equipment cleaning, and lack of effective filtration in the existing technology, and to propose a concentration device for herbal plant extraction.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a concentration device for herbal plant extraction, comprising a tank, a stirring mechanism, a heating mechanism, a condensation and concentration mechanism, and a feeding and discharging mechanism. The stirring mechanism is fixedly connected to the inside of the tank, the heating mechanism is fixedly connected to the outer surface of the tank, the condensation and concentration mechanism is fixedly connected to one side of the top of the tank, and the feeding and discharging mechanism is fixedly connected to the other side of the top of the tank. The stirring mechanism includes a servo motor fixedly connected to the top of the tank, a connecting shaft fixedly connected to the output end of the servo motor, a connecting rod fixedly connected to the top of the connecting shaft, a cleaning scraper fixedly connected to the distal end of the connecting rod, a stirring shaft fixedly connected to the outer surface of the connecting shaft, a connecting plate fixedly connected to the top of the servo motor, and the servo motor fixedly connected to the top of the tank via the connecting plate.

[0010] Furthermore, the heating mechanism includes a fixing plate fixedly connected to the bottom of the tank, and a controller fixedly connected to the top of the fixing plate. The fixing plate and the controller are symmetrically arranged on the outer surface of the tank.

[0011] Furthermore, spiral heating tubes are fixedly connected to both sides of the controller, and the spiral heating tubes are arranged at three equal intervals on the outer surface of the tank.

[0012] Furthermore, the condensation and concentration mechanism includes an outlet pipe fixedly connected to one side of the top of the tank, a concentration condenser fixedly connected to the top of the outlet pipe, and a sealing cap threadedly connected to the top of the condenser.

[0013] Furthermore, the feeding and discharging mechanism includes a feeding pipe fixedly connected to the other side of the top of the tank. A sealing gasket is snapped onto the outer surface of the feeding pipe, and the sealing gasket is snapped into the connection gap between the feeding pipe and the tank. A funnel-shaped feeding port is fixedly connected to the top of the feeding pipe.

[0014] Furthermore, a positioning block is fixedly connected inside the feed pipe and the funnel-shaped feed inlet, a filter frame is snapped onto the top of the positioning block, a filter screen is fixedly connected inside the filter frame, and the aperture size of the filter screen inside the funnel-shaped feed inlet is larger than the aperture size of the filter screen inside the feed pipe.

[0015] Furthermore, the feeding and discharging mechanism includes a discharge port fixedly connected to the bottom of the tank, and a plugging cap is snapped into the inside of the discharge port. The feeding and discharging mechanism also includes a support column fixedly connected to the bottom of the tank, and an anti-slip base plate is fixedly connected to the bottom of the support column.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, through the arrangement of the stirring shaft, cleaning scraper and spiral heating tube, the spiral heating tube provides uniform and stable heat from multiple directions. The servo motor drives the connecting shaft to rotate, which in turn drives the stirring shaft to stir the extract in the tank, promoting uniform heating of the extract. The two work together to significantly improve the concentration efficiency. At the same time, the connecting rod drives the cleaning scraper to rotate along the inner wall of the tank, promptly scraping off the residual extract and keeping the tank clean. The cleaning scraper promptly removes the residual extract on the inner wall of the tank, avoiding residual substances from interfering with the concentration process and breeding bacteria, thus meeting the strict requirements of industrial continuous production for equipment cleanliness and efficient operation.

[0018] 2. In this utility model, through the arrangement of a condenser, a sealing gasket, and a filter screen, the condenser efficiently achieves steam condensation and recovery, saves solvent resources, and reduces production costs. The sealing gasket ensures the sealing of the feeding process, preventing leakage and impurity contamination. The filter screen with a larger aperture in the funnel-shaped feed inlet first intercepts larger impurities in the extract, such as large plant particles, while the filter screen with a smaller aperture in the feed pipe further filters fine impurities, ensuring the purity of the extract entering the tank, reducing damage to the equipment, and improving the quality of the concentrated product.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a concentration device for extracting herbal plants, including a tank 1, a stirring mechanism 2, a heating mechanism 3, a condensation and concentration mechanism 4, and a feeding and discharging mechanism 5. The stirring mechanism 2 is fixedly connected to the inside of the tank 1, the heating mechanism 3 is fixedly connected to the outer surface of the tank 1, the condensation and concentration mechanism 4 is fixedly connected to one side of the top of the tank 1, and the feeding and discharging mechanism 5 is fixedly connected to the other side of the top of the tank 1.

[0028] The following section will describe in detail the specific setup and function of its stirring mechanism 2, heating mechanism 3, condensation and concentration mechanism 4, and feeding and discharging mechanism 5.

[0029] In this embodiment: the stirring mechanism 2 includes a servo motor 21 fixedly connected to the top of the tank 1. The output end of the servo motor 21 is fixedly connected to a connecting shaft 22. The top end of the connecting shaft 22 is fixedly connected to a connecting rod 23. The far end of the connecting rod 23 is fixedly connected to a cleaning scraper 24. The outer surface of the connecting shaft 22 is fixedly connected to a stirring shaft 25. The top of the servo motor 21 is fixedly connected to a connecting plate 26. The servo motor 21 is fixedly connected to the top of the tank 1 through the connecting plate 26.

[0030] The effects achieved by the above components are as follows: When the servo motor 21 starts, it drives the connecting shaft 22 to rotate at high speed. The stirring shaft 25 then stirs the herbal extract in the tank 1 at high speed, causing strong convection in the extract, breaking the limitations of natural convection, achieving uniform heating, and significantly improving the concentration efficiency. At the same time, the connecting rod 23 drives the cleaning scraper 24 to move in a circular motion along the inner wall of the tank 1, promptly scraping off the viscous extract adhering to the inner wall of the tank 1 during the concentration process, preventing the residual liquid from drying and affecting the subsequent concentration effect, reducing the difficulty of equipment cleaning, maintaining the cleanliness of the tank 1, and ensuring the continuous stability of the concentration process.

[0031] Specifically, the heating mechanism 3 includes a fixing plate 31 fixedly connected to the bottom of the tank 1, and a controller 32 fixedly connected to the top of the fixing plate 31. The fixing plate 31 and the controller 32 are symmetrically arranged on the outer surface of the tank 1.

[0032] The effect achieved by the above components is as follows: the controller 32 installed on the top of the fixed plate 31 has a built-in high-precision temperature sensor and intelligent temperature control chip, which can accurately sense the temperature of the tank 1 in real time and precisely control the heating process according to the preset concentration process temperature curve.

[0033] Specifically, spiral heating tubes 33 are fixedly connected to both sides of the controller 32, and the spiral heating tubes 33 are set at three equal intervals on the outer surface of the tank 1.

[0034] The effects achieved by the above components are as follows: During operation, the controller 32 precisely controls the heating of the spiral heating tube 33 based on the feedback temperature information, and heats the tank 1 evenly from multiple directions. In conjunction with the stirring mechanism 2, it ensures that the extract is heated in all directions and evenly, effectively avoiding local overheating that could lead to the decomposition and inactivation of heat-sensitive active ingredients, ensuring product quality during the concentration process, and improving heat transfer efficiency.

[0035] Specifically, the condensation and concentration mechanism 4 includes an outlet pipe 41 fixedly connected to one side of the top of the tank 1, a concentration condenser 42 fixedly connected to the top of the outlet pipe 41, and a sealing cap 43 threadedly connected to the top of the condenser 42.

[0036] The effects achieved by the above components are as follows: During the concentration process of herbal plant extract, the steam generated by heating enters the concentrator condenser 42 through the steam outlet pipe 41. The steam exchanges heat with the cooling medium in the condenser tube in the condenser 42, and is rapidly cooled and liquefied to achieve solvent recovery, reduce production costs, and reduce resource waste. The sealing cover 43 effectively prevents external impurities from entering the interior of the condenser 42, ensuring the condensation effect and solvent recovery quality.

[0037] Specifically, the feeding and discharging mechanism 5 includes a feeding pipe 51 fixedly connected to the other side of the top of the tank body 1. A sealing gasket 52 is snapped onto the outer surface of the feeding pipe 51. The sealing gasket 52 is snapped into the connection gap between the feeding pipe 51 and the tank body 1. A funnel-shaped feeding port 53 is fixedly connected to the top of the feeding pipe 51.

[0038] The effect achieved by the above components is that the sealing gasket 52, which is snapped onto the outer surface of the feed pipe 51, tightly fills the gap between the feed pipe 51 and the tank body 1, preventing leakage of the extract and the mixing of external impurities during the feeding process, and ensuring the purity of the concentration process.

[0039] Specifically, a positioning block 54 is fixedly connected inside the feed pipe 51 and the funnel-shaped feed inlet 53. A filter frame 55 is snapped onto the top of the positioning block 54. A filter screen 56 is fixedly connected inside the filter frame 55. The aperture of the filter screen 56 inside the funnel-shaped feed inlet 53 is larger than the aperture of the filter screen 56 inside the feed pipe 51.

[0040] The effects achieved by the above components are as follows: the filter screen 56 in the filter frame 55 is divided into two layers. The filter screen 56 in the funnel-shaped feed inlet 53 has a larger pore size, which first intercepts larger particulate impurities in the extract, such as coarse plant residues. The filter screen 56 in the feed pipe 51 has a smaller pore size, which further filters fine impurities, thus achieving graded filtration, ensuring the purity of the extract entering the tank 1, reducing the damage of impurities to the equipment, and improving the quality of the concentrated product.

[0041] Specifically, the feeding and discharging mechanism 5 includes a discharge port 57 fixedly connected to the bottom of the tank body 1, and a plug 58 is snapped into the inside of the discharge port 57. The feeding and discharging mechanism 5 also includes a support column 59 fixedly connected to the bottom of the tank body 1, and an anti-slip base plate 510 is fixedly connected to the bottom of the support column 59.

[0042] The effects achieved by the above components are as follows: the support columns 59 fixed at the bottom of the tank 1 are evenly distributed in four places. The anti-slip base plate 510 welded to the bottom of the support column 59 is made of rubber or metal with a rough surface, which increases the friction with the ground, provides stable support for the equipment, and prevents the equipment from shifting or shaking due to vibration, external force and other factors during operation, thus ensuring the safe operation of the equipment.

[0043] Working principle: When using this herbal plant extract concentration equipment, the herbal plant extract is first added into the tank 1 through the funnel-shaped feed inlet 53. After the extract is filtered through the double-layer filter screen 56, it enters the tank 1. Then, the heating mechanism 3 is started. The controller 32 controls the spiral heating tube 33 to heat the tank 1 evenly according to the preset program. At the same time, the stirring mechanism 2 is turned on. The servo motor 21 drives the stirring shaft 25 to stir the extract, so that the extract is heated evenly and the concentration process is accelerated. The cleaning scraper 24 cleans the residue on the inner wall of the tank 1 simultaneously.

[0044] As the extract evaporates upon heating, the steam enters the condenser 42 of the condensation and concentration mechanism 4 through the steam outlet 41. After cooling and liquefaction, the solvent is recovered. When concentration is complete, the plug 58 of the outlet 57 is opened to release the concentrated extract. Throughout the process, all mechanisms work together to achieve efficient and stable concentration of herbal extracts, effectively solving problems such as uneven heating of extracts, low concentration efficiency, easy deactivation of heat-sensitive components, difficulty in equipment cleaning, and lack of effective filtration in existing technologies.
