Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea extraction tank. Background Art

[0002] In the prior art, when producing concentrated tea liquid, tea leaves need to be soaked in water to obtain an extract. During the extraction process, high-temperature extraction is generally used, that is, tea leaves and hot water are mixed in a certain proportion, left to stand for a period of time, and then the extract is sucked out by a pump or vacuum to obtain a tea soup extract. This method takes a long time to extract, and during the extraction process, the temperature will continue to drop, resulting in a decrease in the extraction rate.

[0003] In order to solve the above technical problems, a Chinese patent document (publication number CN209073402U) discloses a high-temperature circulation tea extraction tank, including a tank body, a stirring paddle is provided in the tank body, a discharge port is provided at the bottom of the tank body, the discharge port is connected to a circulation pump, the circulation pump is connected to a heat exchanger, the heat exchanger is connected to the tank body through a reflux pipeline, a reflux pipe connected to the reflux pipeline is provided in the tank body, and a water outlet mesh cover is provided at the bottom of the reflux pipe.

[0004] The above technical solution realizes heat exchange by cooperating with the reflux pipe and the heat exchanger, so that the temperature in the tank body remains relatively stable. However, in actual use, due to the long-term high temperature, the aroma of the tea extract will easily dissipate quickly, and the flavor in the tea extract will be dissipated, and the flavor in the tea extract cannot be maintained. In addition, since the tea extract in the above technical solution is dynamically extracted during the entire extraction process, the tea extract is constantly circulated and heated repeatedly, which also affects the flavor of the tea extract. Utility Model Content

[0005] The utility model aims to provide a tea extraction tank, which can keep the temperature inside the tank body in a relatively stable state during the tea extraction process and at the same time ensure the flavor of the extracted tea soup extract.

[0006] To achieve the above objectives, various aspects of the present application can be implemented in one or more of the following embodiments:

[0007] 1) A tea extraction tank, comprising a plurality of tank bodies, each tank body having a feed port and a discharge port, the feed port being used for allowing tea leaves to enter the tank body, the discharge port being used for discharging tea residues, the tank body being connected to a hot water pipe for conveying hot water into the tank body, the tank body being provided with an extraction pipe for conveying tea extract outward, the outside of the tank body being provided with a heat preservation circulation pipe for transferring heat into the tank body, the outside of the tank body being provided with a cooling circulation pipe for rapidly cooling the tank body, the cooling circulation pipe rapidly cooling the tank body after the tea leaves are extracted from the tank body.

[0008] The utility model uses a heat preservation circulation pipe to transfer heat to the tank body, so that the temperature in the tank body is always maintained at about 90°C, so that the temperature in the tank body remains relatively stable during the tea extraction process, thereby ensuring the extraction temperature, improving the extraction efficiency, and further shortening the extraction time. In addition, compared with the prior art, the utility model uses a cooling circulation pipe designed on the outside of the tank body to quickly cool the tank body to about 20°C after the tank body completes the tea extraction, which greatly reduces the rapid dissipation of the aroma in the tea soup extract of the tea extraction at high temperature, thereby locking the aroma in the tea soup extract in the tea soup extract, and maintaining the flavor in the tea soup extract. At the same time, combined with the static method of the utility model for extraction, hot water is only used once, and then the tea soup extract in the tank body is output to the outside through the extraction pipe, reducing the fluidity of the tea soup extract, thereby ensuring that the tea soup extract can maintain the flavor of the tea soup extract after rapid cooling.

[0009] 2) A tea extraction tank according to 1), wherein:

[0010] The heat preservation circulation pipe includes a steam pipe and a steam circulation pipe. The steam circulation pipe is in a spiral structure. The steam circulation pipe is spirally wound on the outer surface of the middle part of the tank body. One end of the steam circulation pipe is connected to the steam pipe, and the other end of the steam circulation pipe is a closed end.

[0011] The utility model transmits steam toward the steam circulation pipe through the steam pipe, and the steam circulation pipe is spirally wrapped around the outer surface of the middle part of the tank body. Such a design can transfer the steam heat in the steam circulation pipe to the tank body through the principle of heat conduction, so that the middle part of the tank body is heated to ensure the leaching temperature, improve the leaching efficiency, and further shorten the leaching time; and the other end of the steam circulation pipe is a closed end, so that the steam is retained in the steam circulation pipe, and the steam heat has sufficient time to be transferred into the tank body through the steam circulation pipe, thereby ensuring that the temperature inside the tank body remains in a stable state.

[0012] 3) A tea extraction tank according to 1), wherein:

[0013] The cooling circulation pipe includes a tower water circulation pipe with a spiral structure, and the tower water circulation pipe is spirally wound on the outer surface of the lower part of the tank body.

[0014] The utility model adopts a tower water circulation pipe to control the temperature of the outer surface of the lower part of the tank body, and uses the tower water inlet pipe to input tower water into the tubular single filter, so that the tower water is filtered in the tubular single filter and then transported to the tower water circulation pipe through the temperature regulating pipe. At this time, the tower water circulation pipe absorbs the higher temperature in the tank body to avoid excessively high temperature in the tank body, which affects the effect of tea extraction. When the tea leaves are extracted, they are transported to the double-stage tubular cooler through the ice water inlet pipe, cooled by the double-stage tubular cooler and then transported to the temperature regulating pipe. The temperature regulating pipe then transports the cold water to the tower water circulation pipe, and the tea soup extract at the lower part of the tank body is quickly cooled through the tower water circulation pipe, thereby ensuring the flavor of the tea soup extract.

[0015] 4) A tea extraction tank according to 1), wherein:

[0016] The tank body is connected with a cleaning pipe for conveying clean water for flushing, and the tank body is also connected with a sewage pipe for discharging residual water of tea leaves.

[0017] Before tea leaves are extracted, clean water is transported to the tank body through the cleaning pipe for flushing, and after flushing, sewage is discharged through the sewage pipe to ensure the cleanliness of the tank body; in addition, the sewage pipe connected to the tank body of the utility model is used for the residual water of tea leaves accumulated in the tank body after the tea leaves are discharged. After the residual water of tea leaves is discharged, the tank body is flushed through the cleaning pipe, so that the tank body is in a sterile state, thereby ensuring the quality of the tea soup extract.

[0020] The discharge pipe designed in the utility model extends the position of the discharge port downward, thus moving the position of the discharge port closer to the collection box, lowering the height of the discharge port and thus reducing the phenomenon of tea residues being scattered during the discharge process, which makes it difficult to collect. The utility model utilizes the discharge pipe to introduce the tea residues accumulated in the tank body into the collection box.

[0021] In addition, the telescopic cylinder is controlled to drive the closed cover of the closed discharge pipe to flip, so that the pipe mouth of the discharge pipe is exposed, so that the tea residues can be smoothly introduced into the collection box through the discharge pipe for the next step of processing.

[0031] This embodiment uses a heat preservation circulation pipe to transfer heat to the tank body 1, so that the temperature in the tank body 1 is always maintained at about 90°C, so that the temperature in the tank body 1 remains relatively stable during the tea extraction process, thereby ensuring the extraction temperature, improving the extraction efficiency, and further shortening the extraction time. In addition, compared with the prior art, this embodiment uses a cooling circulation pipe designed on the outside of the tank body 1 to quickly cool the tank body 1 to about 20°C after the tea extraction is completed in the tank body 1, which greatly reduces the rapid dissipation of the aroma in the tea soup extract of the tea extraction at high temperature, thereby locking the aroma in the tea soup extract in the tea soup extract and maintaining the flavor in the tea soup extract. At the same time, combined with the static extraction method of this embodiment, the hot water is only used once, and then the tea soup extract in the tank body 1 is output to the outside through the extraction pipe, reducing the fluidity of the tea soup extract, thereby ensuring that the tea soup extract can maintain the flavor of the tea soup extract after rapid cooling.

[0032] Among them, the heat-insulating circulation pipe includes a steam pipe 7 and a steam circulation pipe 5. The steam circulation pipe 5 has a spiral structure. The steam circulation pipe 5 is spirally wound on the outer surface of the middle part of the tank body 1. One end of the steam circulation pipe 5 is connected to the steam pipe 7, and the other end of the steam circulation pipe 5 is a closed end.

[0033] In this embodiment, steam is transported toward the steam circulation pipe 5 through the steam pipe 7, and the steam circulation pipe 5 is spirally wrapped around the outer surface of the middle part of the tank body 1. Such a design can transfer the steam heat in the steam circulation pipe 5 to the tank body 1 through the principle of heat conduction, so that the middle part of the tank body 1 is heated to ensure the extraction temperature, improve the extraction efficiency, and further shorten the extraction time; and the other end of the steam circulation pipe 5 is a closed end, so that the steam is retained in the steam circulation pipe 5, and the steam heat has sufficient time to be transferred to the tank body 1 through the steam circulation pipe 5, thereby ensuring that the temperature in the tank body 1 remains stable.

[0034] In this embodiment, the cooling circulation pipe includes a tower water circulation pipe 6 with a spiral structure, which is spirally wound on the outer surface of the lower part of the tank body 1. The end of the tower water circulation pipe 6 close to the discharge port is connected to a temperature regulating pipe, and the other end of the temperature regulating pipe is connected to the tubular single filter and the two-stage tubular cooler in sequence.

[0035] The present embodiment adopts the tower water circulation pipe 6 to control the temperature of the lower outer surface of the tank body 1, and utilizes the tower water inlet pipe 12 to input tower water into the tubular single filter, so that the tower water is filtered in the tubular single filter and then transported to the tower water circulation pipe 6 through the temperature regulating pipe.

After the tea residue is discharged, the tank body 1 is flushed through the cleaning pipe 10, so that the tank body 1 is in a sterile state, thereby ensuring the quality of the tea soup extract.

[0039] The discharge pipe designed in this embodiment extends the position of the discharge port downward, thus moving the position of the discharge port closer to the collection box, lowering the height of the discharge port and thereby reducing the phenomenon of tea residues being scattered during the discharge process, making it inconvenient to collect. In this embodiment, the discharge pipe is used to introduce the tea residues accumulated in the tank body 1 into the collection box.

[0040] In addition, the telescopic cylinder is controlled to drive the closing cover 4 that closes the discharge pipe to flip, so that the pipe mouth of the discharge pipe is exposed, so that the tea residues can be smoothly introduced into the collection box through the discharge pipe for the next step of processing.
