Description

Technical Field

[0001] This invention belongs to the technical field of Li medicine tea beverage equipment, specifically relating to a multi-raw material adaptable segmented low-temperature extraction and aroma recovery device for Li medicine tea beverages. Background Technology

[0002] Li medicine is a traditional medicinal resource accumulated by the Li people of Hainan through long-term production and daily life practices, possessing unique medicinal value and ethnic characteristics. In recent years, with the rapid development of the health beverage market, Li medicine tea drinks have become increasingly popular among consumers due to their natural and health-promoting properties. Li medicine raw materials are diverse, including different parts such as roots, stems, leaves, flowers, and fruits. The physicochemical properties of the active ingredients contained in each part differ significantly, and their optimal extraction temperatures vary. Most existing Li medicine tea extraction equipment uses a single temperature for uniform extraction, making it difficult to consider the optimal extraction conditions for different raw materials. This results in insufficient extraction of some active ingredients or their destruction due to excessively high temperatures.

[0003] Currently, there are some relevant technical solutions in the field of traditional Chinese medicine extraction, which can carry out different brewing processes with different temperatures, times and times according to different types of Li medicine beverages; and can realize automatic switching extraction of multiple materials and automatic slag discharge.

[0004] However, the aforementioned existing technologies still have the following shortcomings: First, most existing Li medicine tea extraction equipment has a single extraction chamber structure. When it is necessary to process Li medicine raw materials from different parts such as roots, stems, leaves, flowers, and fruits, extraction operations at different temperatures can only be carried out in batches, resulting in low production efficiency and difficulty in achieving continuous production.

[0005] Secondly, existing multi-raw material adaptation solutions mostly use multiple independent extraction tanks to control the temperature separately. The equipment occupies a large area, has high manufacturing costs, and lacks a design for heat synergy between the tanks, resulting in high energy consumption.

[0006] Third, most of the aroma components produced during the extraction process are directly released into the atmosphere, resulting in a significant loss of aroma and affecting the flavor quality and added value of Li medicine tea.

[0007] Fourth, the drain and exhaust ports of the existing extraction device are easily clogged by material residues, affecting the normal operation and service life of the equipment, requiring frequent shutdowns for cleaning, and reducing production efficiency.

[0008] To address the aforementioned issues, there is an urgent need to develop a Li medicine tea extraction device that can simultaneously process multiple Li medicinal materials, achieve segmented low-temperature extraction, effectively recover aroma components, and has anti-clogging functions. Summary of the Invention

[0009] The purpose of this invention is to provide a multi-raw material adaptable segmented low-temperature extraction and aroma recovery device for Li medicinal tea, so as to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a multi-raw material adaptable segmented low-temperature extraction and aroma recovery device for Li medicinal tea, comprising an annular extraction device, wherein the annular extraction device comprises an annular shell, a toothed ring is provided inside the annular shell, a pusher plate is also provided inside the annular shell, the pusher plate is fixedly connected to the toothed ring, the toothed ring is driven by a motor, an inlet is provided on the outer ring of the annular shell, a outlet is provided on the inner ring of the annular shell, a heater is embedded at the bottom of the annular shell, a liquid inlet is provided on the side of the annular shell, and a liquid outlet is provided at the bottom of the annular shell.

[0011] Preferably, the two sides of the inner ring of the annular outer shell are connected by a connecting pipe, and the connecting pipe is connected to the bottom of the dissolved gas tank through a gas supply pipe.

[0012] Preferably, a booster pump is installed on the gas pipeline.

[0013] Preferably, multiple annular extraction devices are provided, and the connecting pipes of each annular extraction device are connected to a gas supply pipe for exhaust.

[0014] Preferably, a ring-shaped extraction device has multiple pusher plates inside its annular shell, forming multiple chambers between the pusher plates, and each chamber is equipped with a heater.

[0015] Preferably, a reverse-push solenoid valve is provided at both ends of the connecting pipe and the inner end of the drain port. The reverse-push solenoid valve includes a valve body, a valve plate is provided inside the valve body, a push-pull rod is provided at the upper end of the valve plate, a movable stop is provided at the inlet of the valve body, the movable stop is cylindrical, and through holes are provided on its side and end face. The movable stop is connected to the push-pull plate through a connecting rod, and a slanted groove is provided on the push-pull plate. One end of the push-pull rod is provided in the slanted groove.

[0016] Preferably, a screw conveyor is provided on the lower side of the discharge port.

[0017] Preferably, the toothed ring has teeth on its inner side and is located at the inner corner of the annular outer shell cavity.

[0018] Preferably, the motor is located outside the annular housing and at the top of the inner ring. The motor output end is connected to a reducer, and a transmission gear is provided at the reducer output end. A notch is opened on the annular housing at the location of the transmission gear, and the transmission gear is connected to the gear ring for transmission.

[0019] The technical effects and advantages of this invention are as follows: Through the structural design of the annular extraction device and the toothed ring driven pusher plate, the continuous feeding, extraction and slag discharge of Li medicinal materials in the annular chamber are realized. The pusher plate can reciprocate in a small amplitude to play a stirring role, which improves the extraction efficiency and uniformity. Multiple annular extraction devices or multiple chambers can be set up and their temperatures controlled separately, enabling segmented low-temperature extraction of raw materials from different parts of Li medicinal herbs, such as roots, stems, leaves, flowers, and fruits. Each raw material is extracted at its own optimal temperature, effectively avoiding the destruction of active ingredients and improving extraction efficiency and product quality. The aromatic gases produced during the extraction process are pressurized and dissolved in water using a dissolved gas tank and a booster pump, which effectively recovers the aromatic components, avoids aroma loss, and enhances the flavor quality and added value of Li medicine tea. By using the structural design of the reverse-push solenoid valve, the reciprocating motion of the movable stop actively pushes away the blockage impurities, effectively solving the problem of blockage at the drain port and exhaust port, improving the operational reliability and service life of the equipment, and reducing downtime for maintenance.

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] This invention provides, for example Figure 1-3The diagram illustrates a multi-raw material adaptable segmented low-temperature extraction and aroma recovery device for Li medicinal tea, comprising a ring-shaped extraction device. The ring-shaped extraction device includes a ring-shaped outer shell 1. A toothed ring 4 is disposed inside the ring-shaped outer shell 1, with teeth on its inner surface. The toothed ring 4 is located at the inner corner of the inner cavity of the ring-shaped outer shell 1 to avoid affecting the inflow and outflow of materials. Two pusher plates 5 are also disposed inside the ring-shaped outer shell 1, and the pusher plates 5 are movably and sealingly connected to the ring-shaped outer shell 1. The pusher plates 5 are fixedly connected to the toothed ring 4. The toothed ring 4 is driven by a motor 6 located outside the ring-shaped outer shell 1. At the top of the inner ring, the output end of motor 6 is connected to a reducer. A transmission gear 7 is installed at the output end of the reducer. A notch 8 is opened on the annular outer shell 1 where the transmission gear 7 is located. The transmission gear 7 is connected to the gear ring 4. A feed inlet 2 is located on the upper left side of the outer ring of the annular outer shell 1, and a discharge outlet 3 is located on the upper right side of the inner ring of the annular outer shell 1. A heater 11 is embedded at the bottom of the annular outer shell 1, and the temperature of the heater 11 is adjustable. A liquid inlet 16 is located on the side of the annular outer shell 1, in the lower half of the annular outer shell 1. A drain outlet is located at the bottom of the annular outer shell 1. The specific working process is as follows: Add the medicinal material from the feed inlet 2. The motor 6 drives the gear ring 4 to rotate counterclockwise, causing the medicinal material to move to the lower half of the annular shell 1. At this time, the two pusher plates 5 are located in the middle of the left and right sides of the annular shell 1. Add water from the liquid inlet 16. After adding water, close the liquid inlet 16 and start the heater 11. Heat to the required temperature and then extract. During this process, the motor 6 can be started to drive the pusher plate to move back and forth slightly, which can move the internal liquid and play a stirring role. After extraction, the solution is discharged from the drain outlet. After the solution is discharged, start the motor 6 to drive the gear ring 4 to rotate counterclockwise. The pusher plate 5 moves and carries the medicinal residue through the discharge outlet 3, and the residue can be discharged. A screw conveyor can be installed on the lower side of the discharge outlet 3 for further conveying of the residue.

[0024] As an embodiment of the present invention, a gas dissolving tank 15 is provided. The gas dissolving tank 15 is connected to the annular outer shell 1 through a pipe. The gas generated during the extraction process contains aroma. Natural discharge causes a large loss of aroma. The gas is transported to the gas dissolving tank 15, where part of the aroma is dissolved in the water of the gas dissolving tank 15, and part of the aroma is recovered.

[0025] Specifically, the two sides of the inner ring of the annular shell 1 are connected by a connecting pipe 10. The connecting pipe 10 can maintain the same pressure on both sides of the inner ring of the annular shell 1 and can also exhaust gas. The connecting pipe 10 is connected to the bottom of the dissolved gas tank 15 through a gas supply pipe 13. In order to increase the dissolved gas effect, a booster pump 14 is installed on the gas supply pipe 13 to increase the pressure inside the dissolved gas tank 15 and improve the dissolved gas effect.

[0026] As an embodiment of the present invention, in order to solve the problem of incompatible extraction temperatures for the roots, stems, leaves, flowers and fruits of Li medicinal materials, multiple annular extraction devices are set up, each containing different Li medicinal materials such as roots, stems, leaves, flowers and fruits, for separate extraction. The connecting pipes 10 of each annular extraction device are connected to a gas supply pipe 13 for exhaust. Each annular extraction device is set with a suitable temperature for extraction, thereby achieving good extraction function for different parts.

[0027] As an embodiment of the present invention, such as Figure 4 As shown, to address the incompatibility of extraction temperatures for the roots, stems, leaves, flowers, and fruits of Li medicinal herbs, a ring-shaped extraction device is equipped with ten pusher plates 5 inside its annular outer shell 1. A chamber is formed between two pusher plates 5, and each chamber holds one type of Li medicinal herb. The bottom chamber holds the raw material with the highest extraction temperature, such as the root of Li medicinal herbs. Raw materials with progressively lower extraction temperatures are placed sequentially on both sides of this chamber. Each chamber is equipped with a heater 11. The heater 11 in the middle chamber is heated first, and the temperature is conducted to both sides, thereby heating and extracting the raw materials in the chambers on both sides. If the heat conduction is insufficient, the heater 11 in the corresponding chamber is turned on for auxiliary heating. The spacing between the two pusher plates 5 is set according to actual needs, that is, different sizes of chambers are set according to requirements to achieve the above-mentioned heat conduction extraction function. Specifically, if the temperature of the chamber is too high after heat conduction, exceeding the minimum temperature required for that chamber, the chamber volume is increased.

[0028] As one embodiment of the present invention, such as Figure 5 As shown, to prevent impurities from clogging the ports and drain outlets of the connecting pipe 10 during venting and draining, a reverse-push solenoid valve 9 is installed. Reverse-push solenoid valves 9 are installed at both ends of the connecting pipe 10 and inside the drain outlet. Each reverse-push solenoid valve 9 includes a valve body 91, with a valve plate 92 inside. The valve plate 92 controls the flow of liquid by switching an electromagnetic coil on and off. A push-pull rod 93 is installed at the upper end of the valve plate 92. A movable stop 94 is installed at the inlet of the valve body 91. The movable stop 94 is cylindrical, with through holes on its side and end faces. The movable stop 94 is connected to a push-pull plate 96 via a connecting rod 95. A groove is provided on the push-pull plate 96, and one end of the push-pull rod 93 is set in the groove. When the electromagnetic coil is energized, the attraction valve plate 92 moves downward and is in the open state. The push-pull rod 93 moves downward with the valve plate 92. By acting on the push-pull plate 96, the movable stop 94 moves outward, and gas or liquid can flow in through the through hole on the movable stop 94 to realize exhaust or drainage. Impurities at the inlet of the valve body 91 can be pushed away by the movable stop 94, reducing the possibility of blockage. If the blockage is serious, the movable stop 94 can be controlled to move repeatedly until the blockage is cleared. After the movable stop 94 retracts, it does not affect the movement of the push plate 5.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
