Description

Technical Field

[0001] This utility model relates to the technical field of liquid concentration, and more specifically, to a concentration device for producing plant extracts. Background Technology

[0002] Liquid concentration is a key process in chemical, food, and pharmaceutical industries. Common physical concentration methods include evaporation, membrane separation, and vacuum concentration. High-temperature evaporation is the most widely used method, which raises the liquid temperature above its boiling point using a heating device, causing rapid vaporization and separation of water. During this process, the stirring device plays a dual role: firstly, it accelerates heat and mass transfer efficiency through mechanical agitation, ensuring a uniform temperature distribution in the liquid phase and preventing localized overheating that could lead to decomposition of active ingredients; secondly, it prevents scaling of high-concentration solutions on the heating surface, which would affect the equipment's heat transfer performance.

[0003] However, traditional mechanical agitation has significant technical bottlenecks. The dynamic sealing structure between the drive shaft and the tank is prone to leakage. In fields with stringent hygiene standards, such as food and pharmaceuticals, the complex mechanical structure is more likely to create cleaning dead zones, fostering microbial contamination. Furthermore, when processing high-viscosity materials, material adhesion often occurs on the agitator blades, not only reducing concentration efficiency but also increasing the workload of disassembling and cleaning the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a concentration device for the production of plant extracts, which can ensure efficient stirring and uniform heating of the liquid, while reducing the use of stirring devices and reducing cleaning difficulty.

[0005] This utility model is achieved through the following technical solution: The plant extract concentration equipment of this utility model includes a concentration tank, a cover at the upper end of the concentration tank, a pair of partition devices vertically disposed inside the concentration tank, a heating device disposed inside the concentration tank, and a condensing device connected to the concentration tank; the partition devices divide the concentration tank into a first chamber and a pair of second chambers respectively located on both sides of the first chamber; the upper and lower ends of the first chamber are connected to the second chambers; a gas supply device is provided in the first chamber.

[0006] Furthermore, the partition device includes a limiting strip disposed on the two opposite inner sidewalls of the concentration tank, a sliding groove formed on the side of the limiting strip away from the inner wall of the concentration tank, and a vertically arranged baffle; both sides of the baffle are disposed in the sliding groove; a gap is provided between the upper end of the baffle and the upper end of the concentration tank, and a gap is provided between the lower end of the baffle and the inner bottom wall of the concentration tank.

[0007] Furthermore, one of the partition devices is provided with a pair of baffles; both sides of the pair of baffles are provided in the sliding groove, and the pair of baffles are partially attached.

[0008] Furthermore, the partition device also includes a drive device for driving the baffle to rise and fall.

[0009] Furthermore, the driving device includes a winding roller disposed above the cover, a motor for driving the winding roller to rotate, a through hole opened on the cover, and a pull rope wound around the winding roller; the pull rope passes through the through hole and is fixedly connected to the upper end of the baffle.

[0010] Furthermore, the driving device also includes a slide tube fixedly disposed in the through hole, and a slide rod slidably disposed in the slide tube; the pull rope includes a first pull rope connected to the winding roller, and a second pull rope connected to the baffle; the first pull rope is connected to the upper end of the slide rod, and the second pull rope is connected to the lower end of the slide rod.

[0011] Furthermore, the heating device includes a steam generator and a plurality of steam pipes connected to the steam generator; the steam pipes pass through the side wall of the concentration tank and are located inside the concentration tank.

[0012] Furthermore, the gas supply device includes multiple exhaust pipes horizontally disposed at the lower end of the first chamber, multiple exhaust nozzles disposed on the side wall of the exhaust pipes, a gas supply pipe connected to the multiple exhaust pipes, a heating box connected to the gas supply pipes, and a blower connected to the heating box; the heating box is provided with heating wires.

[0013] Furthermore, the condensation device includes a vent pipe connected to the cover and a condensation chamber connected to the vent pipe.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: The plant extract concentration equipment of this utility model, during use, sends the plant extract into a concentration tank through an inlet pipe. A heating device then heats the extract, causing the water in the extract to evaporate and be discharged into a condenser. During the heating process, a gas supply device circulates gas into the first chamber. As the gas moves upward, it pulls the extract in the first chamber upward, causing the extract at the top of the first chamber to diffuse into the top of the second chamber. Conversely, the extract at the bottom of the first chamber flows upward, causing the extract at the bottom of the second chamber to enter the bottom of the first chamber. This creates two circulations of extract flow within the concentration tank. This circulation not only agitates the extract, ensuring thorough and uniform heating, but the gas supplied by the gas supply device also effectively carries away the steam generated inside the extract, allowing it to enter the condenser more quickly, improving concentration efficiency, reducing the need for agitation, and making cleaning easier.

Detailed Implementation

[0021] Example

[0022] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 5As shown, the plant extract concentration equipment of this embodiment includes a concentration tank 11, a cover 12 disposed at the upper end of the concentration tank 11, a pair of partition devices 20 vertically disposed inside the concentration tank 11, a heating device 40 disposed inside the concentration tank 11, and a condensing device 60 connected to the concentration tank 11; the partition device 20 divides the concentration tank 11 into a first chamber and a pair of second chambers respectively located on both sides of the first chamber; the upper and lower ends of the first chamber are connected to the second chambers; a gas supply device 50 is provided in the first chamber. Specifically, during use, the plant extract is fed into the concentration tank 11 through the inlet pipe 13. Then, the heating device 40 heats the extract, causing the water in the extract to evaporate and be discharged into the condenser 60. During the heating process, the gas supply device 50 circulates gas into the first chamber. As the gas moves upward, it pulls the extract in the first chamber upward. The extract at the top of the first chamber diffuses to the top of the second chamber, while the extract at the bottom of the first chamber flows upward, causing the extract at the bottom of the second chamber to enter the bottom of the first chamber. This creates two circulations of extract flow in the concentration tank 11. This circulation not only stirs the extract, ensuring thorough and uniform heating, but the gas supplied by the gas supply device 50 also effectively removes the steam generated inside the extract, allowing the steam to enter the condenser 60 more quickly, improving concentration efficiency and reducing the need for stirring. The concentrated extract is then discharged through the drain pipe 14.

[0023] The partition device 20 in this embodiment includes a limiting strip 21 disposed on the two opposite inner sidewalls of the concentration tank 11, a groove 22 formed on the side of the limiting strip 21 away from the inner wall of the concentration tank 11, and a vertically arranged baffle 23; both sides of the baffle 23 are disposed in the groove 22; there is a gap between the upper end of the baffle 23 and the upper end of the concentration tank 11, and a gap between the lower end of the baffle 23 and the inner bottom wall of the concentration tank 11. A pair of baffles 23 are provided in one partition device 20; both sides of the pair of baffles 23 are disposed in the groove 22, and the pair of baffles 23 are partially in contact. Specifically, a pair of baffles 23 separate the middle of the first chamber and the second chamber. This allows the distance between the upper end of the baffle 23 and the upper end of the concentration tank 11 to be adjusted by adjusting the height of the baffle 23, and the distance between the lower end of the baffle 23 and the lower end of the concentration tank 11. When the concentration of the stock solution is low and the fluidity is high, the distance can be appropriately reduced. When the concentration of the stock solution gradually increases, the viscosity increases and the fluidity decreases, the distance can be appropriately increased.

[0024] The partition device 20 in this embodiment also includes a drive device 30 for driving the baffle 23 to rise and fall. The drive device 30 includes a winding roller 31 disposed above the cover 12, a motor 32 for driving the winding roller 31 to rotate, a through hole opened in the cover 12, and a pull rope wound on the winding roller 31; the pull rope passes through the through hole and is fixedly connected to the upper end of the baffle 23. Specifically, the motor 32 drives the winding roller 31 to rotate, thereby pulling or releasing the pull rope, thereby realizing the raising and lowering of the baffle 23.

[0025] The driving device 30 in this embodiment further includes a slide tube 36 fixedly disposed in the through hole, and a slide rod 35 slidably disposed in the slide tube 36; the pull rope includes a first pull rope 33 connected to the winding roller 31, and a second pull rope 34 connected to the baffle 23; the first pull rope 33 is connected to the upper end of the slide rod 35, and the second pull rope 34 is connected to the lower end of the slide rod 35. Specifically, by connecting the first pull rope 33 and the second pull rope 34 through the slide tube 36, the concentration tank 11 can be sealed to prevent gas from escaping to the outside through the through hole.

[0026] The heating device 40 in this embodiment includes a steam generator 41 and a plurality of steam pipes 42 connected to the steam generator 41; the steam pipes 42 pass through the side wall of the concentration tank 11 and are disposed inside the concentration tank 11. Specifically, the concentration tank 11 is mainly heated by steam, but electric heating or a combination of both can also be used.

[0027] The air supply device 50 in this embodiment includes multiple exhaust pipes 51 horizontally disposed at the lower end of the first chamber, multiple exhaust nozzles 52 disposed on the side walls of the exhaust pipes 51, an air supply pipe connected to the multiple exhaust pipes 51, a heating box 53 connected to the air supply pipe, and a blower 54 connected to the heating box 53; the heating box 53 is equipped with heating wires. Specifically, the air entering the blower 54 needs to be thoroughly filtered first, then heated in the heating box 53 and filtered again before being sent to the exhaust pipes 51 through the air supply pipe and discharged to the exhaust nozzles 52. This ensures that the air source is clean and at a high temperature, without contaminating or lowering the temperature of the raw liquid. The blower 54 can also be replaced by a compressed air source.

[0028] The condensing device 60 in this embodiment includes a vent pipe 61 connected to the cover 12 and a condensing chamber 62 connected to the vent pipe 61. Specifically, the condensing device 60 can use a conventional condenser structure.

[0029] In summary, the plant extract concentration equipment of this embodiment delivers the plant extract into the concentration tank 11 through the inlet pipe 13. The heating device 40 then heats the extract, causing the water to evaporate and be discharged into the condenser 60. During heating, the gas supply device 50 supplies gas to the first chamber. As the gas moves upward, it carries the extract upward, causing it to diffuse from the upper part of the first chamber to the upper part of the second chamber. Conversely, the extract at the lower part of the first chamber flows upward, causing it to enter the lower part of the first chamber. This creates two circulations of extract flow within the concentration tank 11. This circulation not only agitates the extract, ensuring thorough and uniform heating, but also allows the gas supplied by the gas supply device 50 to better remove steam generated within the extract, enabling it to enter the condenser 60 more quickly, thus improving concentration efficiency and reducing the need for agitation.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
