Drink capsule with backpressure

Abstract

The invention discloses a drink capsule with backpressure. The drink capsule with the backpressure comprises a shell internally provided with a containing cavity for filling of extraction substances,and a packaging part is fixed at an opening of the upper end of the containing cavity and used for covering; the drink capsule with the backpressure is characterized in that a column table protrudingupwards is arranged at the bottom of the containing cavity, a penetrating liquid outlet channel is arranged on the column table, a filtering sleeve made from a material capable of filtering liquid sleeves the column table, the liquid outlet channel and the containing cavity are divided by the filtering sleeve, a plug made from a flexible material is inserted into an inner port of the liquid outletchannel, and is located in the filtering sleeve, and when pressure inside the containing cavity reaches a certain value, the plug is promoted and deformed to open or further open the inner port of the liquid outlet channel. According to the drink capsule with the backpressure, effective constituents of the extraction substances can be directly and fully extracted out without the backpressure generated by extraction equipment, juice extracted by the drink capsule can be directly flown out to be used for people, and for achieving the aim, a liquid outlet channel with the backpressure does not need to be additionally arranged by adopting the extraction equipment of the drink capsule.

Description

technical field [0001] The invention relates to a beverage capsule used for extraction equipment and filled with extraction substances. The extraction equipment is an extraction equipment that extracts the corresponding juice from the content in the container through high-pressure rapid heating of water, and is suitable for processing beverage capsules packed with ingredients. Container (capsule), the ingredients can produce beverage or edible juice after interacting with the liquid introduced into the capsule, such as hot pressurized water, common ones are coffee extraction machine, tea extraction machine, medicinal material extraction machine, herbal decoction Medicine machine etc. Background technique [0002] Extraction equipment is an extraction equipment that extracts the corresponding juice from the contents of the container by rapidly heating water under high pressure, and is suitable for processing containers (capsules) packed with ingredients, which are mixed with ...

AI Technical Summary

Problems solved by technology

[0005] Looking at the structure of various existing beverage capsules, there is only one cavity for accommodating a quantitative extract (such as coffee powder), that is, the existing capsules can only perform one-level extraction, and cannot achieve graded extraction, so the extraction requirements are relatively high. For high-temperature and high-pressure extraction (requires high-temperature and high-pressure extraction, and the extraction channel requires relatively long) extraction materials, take the extraction of medicinal materials as an example. The medicinal materials cannot be mixed, and they need to be extracted with medicinal herbs. Ordinary capsules are not suitable.
