Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for producing tea extracts. Background Art

[0002] The leaves contain a variety of nutrients such as tea polyphenols, tea pigments, tea proteins, tea polysaccharides, etc. As people's pace of life accelerates, some tea beverages, instant tea and some tea polyphenol health products have become popular among people. When preparing tea extracts, it is necessary to sample the extract for inspection to check whether the quality of the extract is qualified.

[0003] The defects of the existing sampling devices for extract production are: Patent document CN213544116U discloses a simple sampling device for Chinese medicine extracts, and the protected claim "The device includes a hollow tube with an airtight valve and a liquid storage tank connected thereto, and the lower left corner of the liquid storage tank is connected to a drainage tube, which is higher than the top of the liquid storage tank and its tube mouth is tilted downward. The device closes the airtight valve of the hollow tube first, and then extends the liquid storage tank below the liquid surface of the Chinese medicine extract storage container. When the position of the drainage tube mouth reaches the required sampling depth, the airtight valve is opened. At this time, the Chinese medicine extract at the position of the drainage tube mouth will flow into the liquid storage tank under the action of the liquid pressure, and then the liquid storage tank is lifted to complete a specific depth sampling operation. Compared with the existing technology and application examples, the device is simple and convenient, can quickly sample the Chinese medicine extract at a specific depth, can be reused, and has the economic characteristics of environmental protection and low cost." However, when sampling the extract, the device cannot filter the residue contained in the sample very well. Utility Model Content
