Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea processing extraction and separation device. Background Technology

[0002] Tea is a famous beverage, sold both at home and abroad. When tea is processed into finished tea or when substances are extracted from it, the tea leaves generally need to be broken to allow them to dissolve better and increase the extraction speed.

[0003] Chinese patent CN220714880U discloses a tea extraction device. Specifically, it discloses that tea leaves and water, which have been crushed and squeezed inside the casing, can be injected into the chamber through a discharge pipe 2, allowing the water and tea leaves to soak and extract within the chamber. During extraction, the operator can turn on the first drive motor 2, which drives the stirring rod to rotate, thereby mixing the tea leaves and water to meet the extraction requirements. After the tea leaves have soaked and extracted, the valve on the discharge pipe 1 can be opened, and the tea residue can be filtered through a filter screen and discharged, thus meeting the extraction requirements. In the aforementioned patent, after the tea leaves are crushed and squeezed, the squeezed juice and residue enter the chamber together. Since the squeezed juice contains tea polyphenols, and the tea residue contains hydrophobic proteins, when the two are soaked and extracted together, the hydrophobic proteins combine with the tea polyphenols to form an insoluble complex precipitate. The insoluble complex is mainly composed of polyphenol-hydrophobic protein polymers (accounting for >60%), which, together with caffeine, metal ions, etc., form a dense coating layer, including the surface of the tea residue, which significantly inhibits the dissolution of the effective components of the tea residue. Therefore, there is an urgent need for a tea extraction and separation device that can separate the squeezed juice and tea residue, thereby releasing the effective components of the tea residue.
