Detailed Description

The following are embodiments of the present invention and the accompanying drawings are used to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

An extract purifying apparatus based on a process of tea-containing daily chemical products, as shown in fig. 1, comprises a housing 1 and a partition plate 11 vertically arranged in the housing 1 to divide the inner cavity of the housing 1 into a caffeine removing area and a tea polyphenol adsorbing area. Wherein, the baffle 11 can be any number, because the main purpose of this application lies in the absorption of tea polyphenol, consequently can set up several tea polyphenol adsorption zones more. Therefore, when the number of the partition plates 11 is two or more, the inner cavity surrounded by the partition plates 11 serves as a caffeine removing area, the outer part serves as a tea polyphenol adsorbing area, and a tea polyphenol adsorbing area is formed between each partition plate 11 and the casing 1. As shown in fig. 2, four partition plates 11 and four tea polyphenol adsorption areas may be provided.

The upper part of the caffeine removing area is vertically provided with a PF resin column 21, the lower part of the caffeine removing area forms a first liquid accumulating tank 22, the bottom of the caffeine removing area is provided with a first liquid outlet 23, the upper part of the tea polyphenol adsorbing area is vertically provided with a PET resin column 31, the lower part of the caffeine removing area forms a second liquid accumulating tank 32, and the bottom of the caffeine removing area is provided with a second liquid outlet 33. The top surface and the bottom surface of the PET resin column 31 are both provided with microporous separators, the top surface and the bottom surface of the PF resin column 21 are respectively provided with a material port, and the separator 11 is provided with an overflow hole 111; the device also comprises a water pump 4, wherein a water inlet pipe 41 of the water pump 4 is communicated with a material port on the top surface of the PF resin column 21, and a water outlet 421 of a water outlet pipe 42 is close to the top surface of the PET resin column 31. The material port on the bottom of the PF resin column 21 is provided with an absorption tube 24, and the bottom end of the absorption tube 24 is lower than the height of the overflow hole 111. The bottom surface of the PET resin column 31 is higher than the height of the overflow hole 111.

In use, the valves of the first outlet port 23 and the second outlet port 33 are first closed. Then, an extracting solution obtained by solvent extraction or supercritical carbon dioxide extraction is introduced into the PF resin column 21, the extracting solution falls into the first liquid collecting tank 22 after adsorbing caffeine through the PF resin column 21, when the primary adsorption liquid in the first liquid collecting tank 22 is collected to the height of the bottom end of the suction pipe 24, the water pump 4 is started, the primary adsorption liquid is sucked into the PF resin column 21 again by the water pump 4 to adsorb caffeine for the second time, and the obtained secondary adsorption liquid is thrown into the PET resin column 31 through the water outlet pipe 42. The secondary adsorption liquid falls into the second liquid accumulating tank 32 after being adsorbed by the PET resin column 31, when the tertiary adsorption liquid in the second liquid accumulating tank 32 is gathered to the height of the overflow hole 111, the tertiary adsorption liquid flows into the first liquid accumulating tank 22 through the overflow hole 111, and when the tertiary adsorption liquid in the first liquid accumulating tank 22 is gathered to the height of the bottom end of the suction pipe 24, the tertiary adsorption liquid enters the PF resin column 21 under the action of the water pump 4, so that the circulation is repeated, and the caffeine and the tea polyphenol in the extracting solution are continuously adsorbed until the basic adsorption is complete.

In order to further improve the utilization rate of the PET resin column 31, the side surface of the PET resin column 31 close to the partition plate 11 may be connected to the partition plate 11 through a pivot bearing, and the side surface far from the partition plate 11 may be provided with a pivot arm 34. The PET resin column 31 is connected to the spacer 11 through a rotary bearing near the center of the side of the spacer 11. And a liquid sensor is provided at the bottom end of the PET resin column 31 and electrically connected to the rotating arm 34. When the extracting solution flows through the PET resin column 31 and is about to fall into the second liquid collecting tank 32, the liquid sensor detects the liquid outflow, and at this time, a signal is transmitted to the rotating arm 34, so that the rotating arm 34 rotates 180 degrees, the extracting solution flows through the PET resin column 31 again, the adsorption frequency of tea polyphenol is increased, and the extraction rate utilization rate is improved.

In order to improve the adsorption effect of the PF resin column 21, the PF resin column 21 is formed by sequentially connecting a horizontal straight pipe filled with PF resin and an inclined curved pipe. And a plurality of shunt tubes are connected between the adjacent horizontal straight tubes and the inclined curved tubes, and the horizontal straight tubes, the inclined curved tubes and the shunt tubes are communicated in pairs to generate adsorption-shunt-reabsorption effects.

After complete adsorption, desorption is required to release tea polyphenol and caffeine respectively, and ethanol solution is generally used for desorption.

When the device is used, the valves of the first liquid outlet 23 and the second liquid outlet 33 are firstly opened, then ethanol is respectively input into the PF resin column 21 and the PET resin column 31, and caffeine and tea polyphenol are respectively taken out of the resin columns by the ethanol and respectively flow out of the first liquid outlet 23 and the second liquid outlet 33. At this time, since the valve is opened, the desorption liquid does not accumulate in the liquid accumulation tank and flow out from the overflow hole 111, so that the desorption liquid is not mixed.

Meanwhile, the PET resin column 31 can be controlled to rotate by the liquid sensor and the rotating arm 34 during desorption, so that the utilization rate of ethanol is improved.

In addition, for the convenience of control, the PF resin column 21 and the water outlet pipe 42 of the water pump 4 may be both communicated with a total feed pipe 5. The extraction liquid and ethanol can be fed in through the main feed pipe 5. In addition, since the liquid in the apparatus is circulated, when the extract liquid is supplied, it does not matter that a part of the extract liquid directly enters the PET resin column 31 or directly falls into the second liquid collecting tank 32. However, in order to ensure purity, valves are usually provided in each branch of the main feed line 5.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
