[0023] The concentration device comprises a first concentration tank 100, the upper end of the first concentration tank 100 is provided with a second feeding port 150, the second feeding port 150 is connected with the first discharging port 350, the lower end of the first concentration tank 100 is provided with a second discharging port 160, and a heating evaporation mechanism is arranged in the first concentration tank 100.

[0024] ​The tea powder and water are put into the first dissolving tank 300 through the first feeding port 340, the first driving motor 310 drives the first stirring shaft 320 to rotate, and then drives the first stirring paddle 330 to rotate, so as to accelerate the sufficient stirring of the tea powder and water, that is, to accelerate the extraction of tea polyphenols. The first crushing knife 360 can also crush the tea powder in the first dissolving tank 300, so as to accelerate the extraction of tea polyphenols. After the extraction of tea polyphenols is sufficient, the dilute tea polyphenol solution is sent into the first concentration tank through the first discharge port 350 and the second feeding port 150.

[0025] Further, the heating and evaporation mechanism comprises a first heating groove plate 110, a second heating groove plate 120 and a third heating groove plate 130. The first heating groove plate 110 is arranged at the left end of the first concentration tank 100 and is arranged to be inclined downward to the right. The second heating groove plate 120 is arranged at the right end of the first concentration tank 100 and is arranged to be inclined downward to the left. The third heating groove plate 130 is arranged below the first heating groove plate 110 and is arranged to be inclined downward to the right. The second discharge port 160 corresponds to the third heating groove plate 130.

[0026] The dilute tea polyphenol solution passes through the first heating groove plate 110, the second heating groove plate 120 and the third heating groove plate 130 in sequence, is heated and evaporated, and the concentration treatment of the dilute tea polyphenol solution is realized. The evaporated water vapor contacts the steam condensing mechanism upward, and the water vapor condenses into water droplets when it meets cold.

[0027] Further, the upper end of the first concentration tank 100 is provided with a steam condensing mechanism. The steam condensing mechanism comprises a first condensing plate 200 and a first water collecting groove 250.

[0028] The first air conditioner blows cold air into the first S-shaped cavity 230 through the first air inlet pipe 220, absorbs the heat of the first condensing plate 200, so that the water vapor can be quickly condensed into water droplets when it contacts the first condensing plate 200. The hot air blown out of the first air outlet pipe 210 is cooled by the first air conditioner again and then blown into the first S-shaped cavity 230.

[0029] Further, the steam condensing mechanism comprises a first air cooler arranged outside the first concentration tank 100, the first condensing plate 200 is internally provided with a first S-shaped cavity 230, one end of the first S-shaped cavity 230 is provided with a first air inlet pipe 220, the other end of the first S-shaped cavity 230 is provided with a first air outlet pipe 210, and the first air inlet pipe 220 and the first air outlet pipe 210 are connected with the first air cooler.

[0030] After being heated and evaporated through the first heating groove plate 110, the second heating groove plate 120 and the third heating groove plate 130, the water in the dilute tea polyphenol solution is evaporated, the water vapor floats upwards and contacts the first condensing plate 200, then the water vapor is condensed into water droplets after being cooled, and the water droplets slide downwards along the first condensing plate 200 and fall into the first water collecting groove 250, and the water can be discharged through the first water discharge pipe 251, so that the water content in the first concentration tank 100 is continuously reduced.

[0031] Further, the lower end of the first condensing plate 200 is provided with a plurality of first dovetail grooves 240, the right end of the first dovetail groove 240 is provided with a first water guide rope 260, and the other end of the first water guide rope 260 is arranged in the first water collecting groove 250.

[0032] When the first condensing plate condenses the water vapor, the first dovetail groove can adsorb the water droplets and guide the water droplets to the end of the first dovetail groove, the water droplets flow into the first water collecting groove through the flow guide of the first water guide rope, the probability of the water droplets falling into the tea polyphenol solution again is reduced, and the extraction efficiency of the tea polyphenol can be improved.

[0033] It is worth mentioning that the first air cooler and other technical features involved in the utility model patent application should be regarded as prior art, the specific structure, working principle and possible control mode and spatial arrangement mode of these technical features can be selected according to the prior art, and should not be regarded as the utility model point of the utility model patent, and the utility model patent will not be further expanded and described in detail.
