Description

Technical Field

[0001] This utility model belongs to the field of concentration technology, specifically relating to a tea polyphenol heating and concentration device. Background Technology

[0002] Tea polyphenols are a general term for polyphenolic substances in tea. They are easily soluble in water and possess excellent antioxidant, anti-radiation, anti-aging, lipid-lowering, antibacterial, and enzyme-inhibiting effects. The extraction processes for tea polyphenols mainly include organic solvent extraction, ion precipitation extraction, adsorption separation extraction, and supercritical fluid extraction. Regardless of the extraction method, the obtained tea polyphenols need to be purified and concentrated. Steam concentration devices are commonly used equipment in the tea polyphenol concentration process. Currently, the steam generated after heating tea polyphenols tends to remain at the top of the evaporation chamber and condense into water droplets that fall into the tea polyphenol solution, thus reducing the efficiency and quality of tea polyphenol concentration.

[0021] Preferred embodiment.

[0022] This embodiment provides a tea polyphenol heating and concentration device, including:

[0023] The first concentration tank 100 has a first feed inlet 150 at its upper end;

[0024] A heating and evaporation mechanism is provided inside the first concentration tank 100. The heating and evaporation mechanism includes a first heating plate 110, a second heating plate 120, and a third heating plate 130. The first heating plate 110 is located at the left end of the first concentration tank 100 and is inclined downward to the right. The second heating plate 120 is located at the right end of the first concentration tank 100 and is inclined downward to the left. The third heating plate 130 is located below the first heating plate 110 and is inclined downward to the right. The right end of the first concentration tank 100 is provided with a first discharge port 160, which corresponds to the third heating plate 130.

[0025] A steam condensation mechanism is disposed at the upper end of the first concentration tank 100.

[0026] Dilute tea polyphenol solution is fed into the first concentration tank 100 through the first feed inlet 150. The dilute tea polyphenol solution passes through the first heating tank 110, the second heating tank 120 and the third heating tank 130 in sequence. After heating and evaporation, the dilute tea polyphenol solution is concentrated. The evaporated water vapor comes into contact with the steam condensation mechanism and condenses into water droplets.

[0027] Furthermore, the steam condensation mechanism includes a first condensing plate 200 and a first water receiving tank 250. The first condensing plate 200 is disposed at the upper end of the first concentration tank 100, and the first condensing plate 200 is inclined to the lower right. The first water receiving tank 250 is disposed at the right end of the first concentration tank 100, corresponding to the lower part of the first condensing plate 200. The right end of the first water receiving tank 250 passes through the first concentration tank 100 and is provided with a first drain pipe 251. After being heated and evaporated by the first heating plate 110, the second heating plate 120 and the third heating plate 130, the water in the diluted tea polyphenol solution evaporates. The water vapor rises and comes into contact with the first condensing plate 200, where it condenses into water droplets and slides down the first condensing plate 200 into the first water receiving tank 250. The water can be discharged through the first drain pipe 251, ensuring that the water in the first concentration tank 100 continuously decreases.

[0028] Furthermore, the steam condensation mechanism includes a first air cooler, which is disposed outside the first concentration tank 100. A first S-shaped cavity 230 is provided within the first condensing plate 200. A first air inlet pipe 220 is provided at one end of the first S-shaped cavity 230, and a first air outlet pipe 210 is provided at the other end. The first air inlet pipe 220 and the first air outlet pipe 210 are connected to the first air cooler. The first air cooler introduces cold air into the first S-shaped cavity 230 through the first air inlet pipe 220, absorbing heat from the first condensing plate 200. This allows water vapor to quickly condense into water droplets upon contact with the first condensing plate 200. Meanwhile, the hot air blown out through the first air outlet pipe 210 is cooled again by the first air cooler and blown into the first S-shaped cavity 230. Meanwhile, the lower end of the first condenser plate 200 is uniformly provided with a plurality of first dovetail grooves 240. The first dovetail grooves 240 facilitate the adsorption of water droplets, thereby ensuring that after the steam condenses into water droplets, it is not easy to drip directly, but is adsorbed in the first dovetail grooves 240 and slides down along the first dovetail grooves 240 into the first water receiving tank 250.

[0029] Furthermore, the lower ends of the first heating plate 110, the second heating plate 120, and the third heating plate 130 are all provided with first heating elements 140. The upper end of the first heating plate 110 is provided with a plurality of first V-grooves 111, the upper end of the second heating plate 120 is provided with a plurality of second V-grooves, and the upper end of the third heating plate 130 is provided with a plurality of third V-grooves. The first V-grooves 111 increase the contact area between the diluted tea polyphenol solution and the first heating plate 110, thereby improving the heating and evaporation effect. The second V-grooves and the third V-grooves increase the contact area between the diluted tea polyphenol solution and the second heating plate 120 and the third heating plate 130, respectively, thus improving the concentration efficiency.

[0030] Furthermore, the upper end of the first concentration tank 100 is provided with a first exhaust pipe 170, and the first exhaust pipe 170 is provided with a first pressure valve 171. When the air pressure inside the first concentration tank 100 is too high, the first pressure valve 171 will open to release the pressure, ensuring the safe use of the first concentration tank 100.

[0031] It is worth mentioning that the technical features of air conditioners and other related technologies involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, control method, and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the utility model point of this utility model patent. This utility model patent will not elaborate further.

[0032] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
