Description

TECHNICAL FIELD

[0001] The present application relates to the field of tea extraction, in particular to an extraction device for improving the extraction rate of tea. BACKGROUND

[0002] Tea extraction mainly uses finished tea or semi-finished tea as raw material to extract the soluble substances in tea with normal temperature water, and the tea juice obtained by filtering out the tea residue. Some are concentrated and dried to prepare solid or liquid tea. After the tea is placed in normal temperature water for extraction, the tea residue needs to be removed.

[0003] The patent with application number 202320180241.3 discloses a tea extraction device, which comprises a shell, a soaking cavity, an extraction cavity, a ring cavity, a ring filter, a flow-through hole, a matching hole, a ring hole, a ring filter screen, a ring cover, a cavity cover, a power device, an output shaft, a stirring blade and an upper pull rod. Bulk tea or tea cakes are placed in the soaking cavity by opening the cavity cover, and after the cavity cover is closed, the tea is further broken up by the stirring blade and other components, so that the liquid added into the soaking cavity can fully soak the tea. After soaking for a period of time, the upper pull rod is pulled to move the filter upward in the ring cavity, so that the matching hole is aligned with the ring hole, and the liquid in the soaking cavity flows into the ring filter.

[0004] At present, the existing tea is only extracted by warm water soaking. Since the outflow efficiency of the components in the tea is low, the above technical solution uses the stirring blade to crush the tea and make it fully contact with water. However, the tea is easily blocked after being crushed, and the small tea particles are difficult to filter, resulting in poor extraction and filtration effect of the tea.
