Tea capsule capable of bearing high-pressure extraction

Abstract

The invention discloses a tea capsule capable of bearing high-pressure extraction. The tea capsule comprises a hollow cup body with an opening in the upper end, wherein a sealing film is arranged at the opening end of the cup body; a separation film is arranged on the inner side of the cup body; the separation film divides an inner cavity of the cup body into an upper cavity and a lower cavity; afirst supporting sheet is arranged on the inner wall of the lower cavity; the lower cavity is filled with raw tea leaves; a groove is formed in the bottom of the inner side of the cup body; an upper opening of the groove is covered with an ultrafiltration membrane and an aluminum foil film in sequence from top to bottom; a supporting shell is arranged at the center of the bottom of the groove; anannular convex edge is arranged on the outer side of the supporting shell; a notch is formed in the upper end of the annular convex edge; an arc-shaped convex edge is arranged on the outer side of theannular convex edge; triangular convex thorns are arranged at the upper end of the arc-shaped convex edge; a water outlet pipe communicating with the supporting shell is arranged in the middle of thelower end of the cup body; and a plurality of water outlet holes are formed in the outer edge of the supporting shell. The tea capsule disclosed by the invention can bear the high-pressure extractionand also can filter out broken tea in tea soup, so that the formation of tea soup foams is reduced, and the quality of the tea soup is obviously improved.

Description

technical field [0001] The invention relates to the technical field of tea making equipment, in particular to a tea capsule that can withstand high-pressure extraction. Background technique [0002] Tea is a kind of beverage that is deeply loved by the public. Due to the accelerated pace of life, convenient and fast tea making machines and tea capsules are favored by consumers. [0003] Tea capsules in the prior art generally encapsulate tea leaves or tea extracts inside the capsule, and are used in conjunction with a tea maker. When making tea, the upper and lower covers of the tea capsule are pierced by the tea maker and poured into the tea capsule. Water is injected to brew the tea leaves, and the tea flows out through the pores for people to drink. [0004] Although the above-mentioned type of tea capsule improves the convenience of tea brewing to a certain extent, it still has the following defects in actual use: [0005] 1) The hardness of the tea capsules in the pri...

AI Technical Summary

Problems solved by technology

[0005] 1) The hardness of the tea capsules in the prior art is relatively low. Under the dual effects of water temperature and pressure, the capsules are easily deformed. After the deformation of the capsules, the tea soup is easy to leak from the inside of the capsules, which not only affects the normal use of the tea capsules, but also has certain defects. Potential safety hazards; and the use of metals with relatively high hardness as the outer shell of tea capsules will increase the difficulty of manufacturing tea capsules, high production costs, and low economic benefits;

[0006] 2) When the piercing mechanism of the tea making machine punctures the lower cover of the tea capsule, the original tea leaf or tea extract powder will flow out together with the tea soup, which not only affects the taste and color of the tea soup, but also causes More bubbles are formed on the liquid surface of the tea soup, which seriously affects the quality of the tea soup brewed from the tea capsules
