Liquids containing impurities, astringent substances, and other unwanted substances are discharged into the receiving tank through a T-shaped tube.

Description

Technical Field

[0001] This utility model relates to the field of tea polyphenol production technology, specifically to a raw material extraction and purification device for tea polyphenol production. Background Technology

[0002] Tea polyphenols are one of the main active ingredients in tea, possessing high levels of antioxidant and anti-inflammatory properties, and are widely used in health products, cosmetics, and food. The main source of tea polyphenols is tea, especially green tea, white tea, and oolong tea. Tea leaves are rich in tea polyphenols, particularly unfermented green tea and white tea.

[0003] For example, a separation and purification device for cosmetic raw material production, disclosed in CN213527734U, includes a separation mechanism and a filtration mechanism. The separation mechanism includes a base, a filter shell, and a protective cover. The filter shell is disposed on the upper surface of the base, the protective cover is disposed above the filter shell, and a grinding assembly is disposed above the protective cover. The filtration mechanism includes a filter box, a filter plate, and a discharge trough. The filter plate is disposed on the bottom inner side of the filter box, the discharge trough is installed on the lower surface of the filter box, and a discharge pipe is installed on the lower surface of the discharge trough. This device has a simple structure, reasonable design, and low production cost. By filtering the raw materials twice, the purification effect is greatly guaranteed, and waste is easy to clean, making it highly practical.

[0004] The aforementioned patent proposes that the filter shell initially filters the juice of the raw material, and the filter plate filters it again. After two filtrations of the raw material, the purification effect is greatly guaranteed, and it is also convenient to clean up the waste. However, in actual use, when multiple filtrations are performed, there will be relatively viscous components in the raw material (such as highly viscous substances, fibers or oils). The viscous components are easy to clog the filtration equipment. The filter shell and filter plate are prone to a decrease in flow rate or even blockage due to excessive solid residues, which affects the filtration efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a raw material extraction and purification device for tea polyphenol production, so as to solve the problem mentioned in the background art that viscous components easily clog the filtration equipment.

Tea leaves are poured into the circular frame, and two sets of side circular plates are placed inside the circular frame, covering the tea leaves. Hot water is poured into the reaction tank to soak the tea leaves and release the tea polyphenols.

The cylinder extends, which drives the tank cover and motor to move upward. The side circular plate is restricted by the bottom rod and moves downward inside the circular frame. The downward moving side circular plate squeezes the tea leaves and squeezes out the tea water mixed between the tea leaves. It is discharged into the reaction tank through the filter screen to avoid the tea leaves clogging the filter screen. The molecular sieve inside the I-shaped tube selectively adsorbs tea polyphenols and purifies the tea polyphenols. The liquid containing impurities, astringent substances, and other unwanted liquids will be discharged into the receiving tank through the T-shaped tube. Attached Figure Description

A cylinder 15 is installed at the top of the side plate 14, and a snap-fit ​​component 17 is hinged to one side of the top of the extraction tank 11.

[0018] The extraction tank 11 includes an outer tank 111 and a reaction tank 112 installed inside the outer tank 111. A tank cover 16 is installed on the top of the reaction tank 112. The moving ends of the cylinder 15 are installed on both sides of the bottom end of the tank cover 16. An air inlet pipe 12 is installed through the outer side of the outer tank 111. A discharge component 18 is installed through the outer surface of the outer tank 111 and the reaction tank 112 and on one side of the air inlet pipe 12. A receiving component 19 is installed at the bottom end of the discharge component 18.

[0019] A motor 13 is installed at the top of the can lid 16. A rotating shaft 131 is installed at the bottom of the motor 13. A bottom circular plate 132 is installed at the bottom of the rotating shaft 131. Positioning rods 133 are installed at the top of the bottom circular plate 132 and on both sides of the rotating shaft 131. A circular frame 134 is installed at the top of the bottom circular plate 132 and is located outside the rotating shaft 131. A filter screen 135 is installed at the bottom of the rotating shaft 131. Side circular plates 136 are installed on both sides inside the circular frame 134. The positioning rods 133 are inserted into the bottom of the circular frame 134 so that when the rotating shaft 131 rotates, the positioning rods 133 cooperate with the bottom circular plate 132 to drive the circular frame 134 to rotate. After the tea leaves react with hot water for a certain period of time (such as 10-20 minutes), the tea polyphenols can be effectively released.

[0020] An inner connection block 113 is installed on the inner wall of the reaction vessel 112. A side connection circular plate A114 and a side connection circular plate B115 are installed on the top of the inner connection block 113. A rotating hole 116 is opened through the middle of the contact end of the side connection circular plate A114 and the side connection circular plate B115. The rotating hole 116 facilitates the rotation of the rotating shaft 131 inside it. The inner connection block 113 is located above the circular frame 134.

[0021] Bolt A117 is threaded to the top of the side connecting circular plate A114 and the side connecting circular plate B115. Bottom rods 118 are installed at the bottom of both the side connecting circular plate A114 and the side connecting circular plate B115. An oblique guide hole 119 is opened through one side of the bottom of the reaction vessel 112 and the outer vessel 111. The position of the bolt A117 is aligned with the position of the inner connecting block 113.

[0022] In this embodiment: the circular frame 134 is located inside the reaction vessel 112. Tea leaves are poured into the circular frame 134, and two sets of side circular plates 136 are placed inside the circular frame 134, covering the tea leaves.

Then, the side connecting circular plates A114 and B115 are placed on the top of the inner connecting block 113. The opening of the rotating hole 116 facilitates the rotation of the rotating shaft 131. When the motor 13 controls the rotating shaft 131 to rotate, it will drive the circular frame 134 to rotate through the bottom circular plate 132 and the positioning rod 133, causing the tea leaves to rotate in the hot water, increasing the permeability of the solvent to the tea leaves, thereby improving the extraction efficiency of tea polyphenols, that is, obtaining the preliminary extract of tea polyphenols.

[0023] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The discharge component 18 includes a discharge pipe 181 and a water valve 182 installed at one end of the discharge pipe 181. A bent pipe 183 is installed at one end of the water valve 182. A lower connecting ring A184 is installed at the bottom end of the bent pipe 183. An I-shaped pipe 187 is installed at the bottom end of the bent pipe 183. A T-shaped pipe 185 is installed at the bottom end of the I-shaped pipe 187. A dense mesh 188 is installed at the bottom inside the bent pipe 183 and the bottom inside the I-shaped pipe 187. An I-shaped pipe 187 is provided inside the I-shaped pipe 187. Bolts B186 are threadedly connected between the lower connecting ring A184 and the top end of the I-shaped pipe 187, and between the top end of the T-shaped pipe 185 and the bottom end of the I-shaped pipe 187. A molecular sieve 189 is provided inside the I-shaped pipe 187. The molecular sieve 189 facilitates the absorption of tea polyphenols. One end of the discharge pipe 181 is installed outside the inclined hole 119.

[0024] The receiving component 19 includes a receiving tank 191 and a rubber cover 192 threaded onto the outer side of the upper end of the receiving tank 191. The top of the rubber cover 192 has an insertion hole 193. The receiving tank 191 is used to collect tea.

[0025] In this embodiment: After soaking, the water valve 182 is opened. The tea water inside the reaction tank 112 flows along the inclined inlet 119, the drain pipe 181, the water valve 182, and the inside of the bent inlet pipe 183. The tea water passes through the lower connecting ring A184 and enters the inside of the I-shaped tube 187. The cylinder 15 extends, which drives the tank cover 16 and the motor 13 to move upward. The side circular plate 136 is restricted by the bottom rod 118 and moves downward inside the circular frame 134. The downward moving side circular plate 136 squeezes the tea leaves, squeezing out the tea water mixed between the tea leaves. It is discharged into the inside of the reaction tank 112 through the filter screen 135 to avoid the tea leaves clogging the filter screen 135 and affecting the flow of tea water. The molecular sieve 189 inside the I-shaped tube 187 selectively adsorbs the tea water. Tea polyphenols are purified. Liquids containing impurities, astringent substances, and other unwanted substances are discharged into the receiving tank 191 through the T-shaped tube 185. After the tea polyphenols in the tea water are completely adsorbed, the bolt B186 is turned out, and the I-shaped tube 187 is separated from the lower connecting ring A184. The I-shaped tube 187, T-shaped tube 185, and receiving component 19 are removed. The receiving tank 191 is held and rotated, and the receiving tank 191 is taken out from the bottom of the rubber cover 192, so that the molecular sieve 189 inside the I-shaped tube 187 can be poured out. The molecular sieve 189 adsorbing tea polyphenols is heated to an appropriate temperature (between 50°C and 150°C) so that the tea polyphenol molecules gain enough energy to overcome the adsorption force and desorb from the molecular sieve 189.
