Description

Technical Field

[0001] The utility model relates to the technical field of tea polyphenol extraction devices, in particular to a device for extracting tea polyphenols from aged tea. Background Art

[0002] Tea polyphenols in aged tea have strong antioxidant properties and physiological activity. They are scavengers of free radicals in the human body and can inhibit lipoxygenase and lipid peroxidation in skin mitochondria, thus having anti-aging effects. There is a corresponding extraction process for the extraction of tea polyphenols in aged tea.

[0003] In the extraction process of tea polyphenols from old tea, the old tea fragments are generally placed in a lifting tank first, and then the required pure water, ethanol and other solvents required in the extraction process are added, and then the solvent is steamed. During the steaming process, the components containing tea polyphenols in the old tea leaves will be gradually precipitated under the action of the solvent, and then the tea polyphenol extract is obtained. Finally, the tea polyphenols are extracted using the corresponding process flow.

[0004] During the process of steaming to obtain tea polyphenols extract, the old tea leaves are affected by the solvent in the steaming process according to their own weight, volume and density. Some tea leaves will float to the surface of the dissolved water, or they may adhere to the inner wall of the extraction tank above the water surface, which will affect the extraction operation of the tea leaves, resulting in incomplete extraction of the tea leaves and affecting the extraction efficiency of tea polyphenols.

[0005] Based on the above situation, it is necessary to design a device for extracting tea polyphenols from aged tea to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0020] Reference Figure 1-Figure 4As shown, a device for extracting tea polyphenols from aged tea comprises a tank body 1, which is provided with a water inlet pipe 2 and a water outlet pipe 3 for adding a solvent and taking out the tea polyphenol extract, respectively. In order to facilitate the restraint of the aged tea fragments added into the tank body 1 so that they do not float, the device for extracting tea polyphenols further comprises a feeding barrel 4 located inside the tank body 1 and used for placing the aged tea fragments. The feeding barrel 4 is connected to the interior of the tank body 1 through a plurality of through holes opened on the feeding barrel 4. The size of the through holes is set according to the size of the aged tea fragments, ensuring that the solvent can freely enter and exit the feeding barrel 4 without causing the aged tea fragments therein to move into the interior of the tank body 1. In order to facilitate the addition of materials into the feeding barrel 4, a feeding pipe 5 is connected to the feeding barrel 4. The feeding pipe 5 passes through the top of the tank body 1 and extends to the outside. The old tea fragments are poured into the material pipe 5, and the material will enter the material barrel 4 along the feed pipe 5. When the material is cooked together with the solvent, in order to ensure that the material does not gather together and affect the extraction efficiency, a stirring component is provided inside the material barrel 4, and the stirring component is driven by the motor 20 provided on the tank body 1. The stirring component is used to stir and disturb the material inside the material barrel 4, so that the material is always in a broken state. Finally, when performing the next batch of extraction operations, in order to facilitate the removal of the material inside the material barrel 4, a discharging mechanism is provided on the material barrel 4, and the material inside the material barrel 4 is discharged to the outside of the tank body 1 through the discharging mechanism. During this process, the old tea fragments are always confined in the material barrel 4, and the solvent inside the tank body 1 can contact the old tea fragments through the through hole and perform the extraction process on them.

[0021] Furthermore, in order to prevent the solvent in the tank body 1 from flowing into the feed pipe 5 when in use, a number of limit rods 15 are connected to the output end of the feed pipe 5 in an axially sliding manner along the feed pipe 5, and a buoyancy block 16 is fixedly connected to one end of the number of limit rods 15. The buoyancy block 16 is connected to the side close to the feed pipe 5, and the blocking block 17 corresponds to the opening position of the output end of the feed pipe 5. When solvent is injected into the tank body 1, as the water level gradually rises, the water surface will push the buoyancy block 16 to move upward, and under the action of the limit rod 15, it will move along the central axis direction of the feed pipe 5, and the blocking block 17 will gradually approach the output end of the feed pipe 5 and finally engage with the output end of the feed pipe 5. When there is no solvent in the tank body 1, the buoyancy block 16 and the limit rod 15 are away from the output end position of the feed pipe 5 under the action of gravity. At this time, the input end of the feed pipe 5 and its output end are in a connected state.

[0022] In order to ensure that the blocking block 17 is sufficiently stable when it is engaged at the output end of the feeding pipe 5, a magnetic block 18 is fixedly connected to the end of several limit rods 15 away from the buoyancy block 16, and a magnetic block 2 19 is connected to the upper part of the feeding pipe 5, and the magnetic block 18 and the magnetic block 2 19 are magnetically connected. When the blocking block 17 is engaged on the output end of the feeding pipe 5, the magnetic block 18 and the magnetic block 2 19 are magnetically attracted to each other, and combined with the buoyancy of the liquid, the blocking block 17 will be stably engaged on the output end of the feeding pipe 5. When there is no solvent in the tank body 1, the force of the magnetic connection between the magnetic block 18 and the magnetic block 2 19 is less than the buoyancy block 16, the limit rod 15 and the blocking block 17's own gravity. Therefore, the blocking block 17 will normally be away from the output end position of the feeding pipe 5 when there is no liquid.

[0023] Among them, the stirring assembly includes a rotating shaft 6 whose one end is rotatably connected to the tank body 1, a stirring rod 1 7 and a stirring rod 2 8 located inside the feeding barrel 4, the other end of the rotating shaft 6 extends to the inside of the feeding barrel 4 and is fixedly connected to a support rod 9, one end of the rotating shaft 6 is connected to the output end of the motor 20, the stirring rod 1 7 is fixedly connected to the rotating shaft 6, and the stirring rod 1 7 contacts the inner top wall of the feeding barrel 4, and the stirring rod 2 8 is connected to the support rod 9. When in use, the motor 20 is started, and the output end of the motor 20 drives the rotating shaft 6 to rotate, and then drives the stirring rod 1 7 and the stirring rod 2 8 connected to the rotating shaft 6 to rotate, the stirring rod 1 7 will break up the material that floats up and hits the top of the feeding barrel 4, and the stirring rod 2 8 will disturb the material suspended in the feeding barrel 4, so that it can better contact with the solvent, thereby improving the extraction efficiency.

[0024] In order to prevent the material from adhering to the through-hole, the stirring assembly also includes a scraper rod 10 connected to the support rod 9. The scraper rod 10 contacts the side wall of the material barrel 4. When the scraper rod 10 is driven and rotated by the rotating shaft 6, the scraper rod 10 will remove the material attached to the through-hole, thereby reducing the interference with the flow of the solvent.

[0025] Furthermore, the discharging mechanism includes a discharging pipe 11 connected to the feeding barrel 4 and a telescopic rod 12 arranged in the discharging pipe 11. A sleeve 13 is fixedly connected to the discharging pipe 11, and the telescopic rod 12 is installed in the sleeve 13. The movable end of the telescopic rod 12 extends to the outside of the sleeve 13 and is connected to a piston block 14. The piston block 14 movably interferes with the input end of the discharging pipe 11. During use, when the movable end of the telescopic rod 12 drives the piston block 14 to interfere with the input end of the discharging pipe 11, the input end of the discharging pipe 11 and its output end are in a disconnected state. When the movable end of the telescopic rod 12 drives the piston block 14 away from the input end of the discharging pipe 11, the input end of the discharging pipe 11 and its output end are in a connected state. When the material in the feeding barrel 4 is cleaned, the material will flow out along the discharging pipe 11, preparing for the next extraction operation.
