Embodiment 1

[0027] The black tea of ​​the present invention is placed in the packing container of the air-breathing air extraction valve that seals and filter membrane is arranged antifouling aging method, comprises the following steps:

[0028] a) dark tea is contained in the packing container that ventilating air extraction valve is installed, and makes packing container keep airtight state;

[0029] b) The breathable air pumping valve includes a breathable valve and an air pumping valve, and the first adjustment protective cover of the breathable valve is tightened so that the breathable valve is in an airtight airtight state;

[0030] c) Unscrew the cover of the air extraction valve installed on the packaging container, use the prepared vacuum pump to align the air extraction nozzle with the air extraction hole of the air extraction valve, and use the elastic deformation of the sealing sheet to extract air, so that the vacuum degree in the packaging container Reach ≤150~250Pa, and at ...

Embodiment 2

[0047] The black tea of ​​the present invention is placed in the packing container of the air-breathing air extraction valve that seals and filter membrane is arranged antifouling aging method, comprises the following steps:

[0048] e) black tea is contained in the packing container that ventilating air extraction valve is installed, and makes packing container keep airtight state;

[0049] f) Unscrew the adjustment protective cover of the ventilating exhaust valve installed on the packaging container, enable the exhaust valve form of the ventilating exhaust valve, and use the prepared vacuum pump to align its exhaust nozzle with the exhaust hole of the exhaust valve and pass the sealing film The elastic deformation of the packaging container is used to pump air, so that the vacuum degree in the packaging container reaches ≤150-250Pa, the air in the packaging container and the dust particles and microorganisms carried by it are reduced to the minimum, and there is very little ...

Abstract

The invention provides an anti-pollution aging method for putting black tea into a packaging container with a ventilated extraction valve having sealing and filter films and specially designed packaging container for implementing the method, wherein the method comprises the following steps of: a) putting the black tea into the packaging container with the ventilated extraction valve, and keeping the black tea in a sealing state; b) screwing on a first regulation protecting cover of aventilated valve, wherein the ventilated extraction valve comprises a ventilated valve and an extraction valve; c) screwing off a sealing cover of the extraction valve, pumping by a vacuum pump so that the vacuum degree in the packaging container is smaller than or equal to 150-250 Pa, reducing air, dust particles and microorganism carried by the air in the container to least, and screwing on the sealing cover of the extraction valve so as to keep the extraction valve in the sealing state; and d) loosening the first regulation protecting cover of the ventilated valve reversely by screwing, causing the air to pass through a micropore filter film to enter in and out the bag, preventing the particles and microorganism outside from entering into the packaging container, naturally oxidizing the tea to finish the anti-pollution aging so that the tea is more fragrant when the time is longer. The invention also provides the packaging container for implementing the method.

Description

technical field [0001] The present invention relates to a tea packaging, storage and aging method and its special device, in particular to a method of anti-pollution and aging of black tea in a packaging container with a sealing and filter membrane ventilating valve and its realization The packaging container specially designed by the above method. Background technique [0002] The aging of food, namely aging, generally refers to the state in which the quality of food changes with the passage of time during the storage process. If the quality develops in the direction of degradation and deterioration, it is generally called aging and deterioration, such as the aging and deterioration of rice. If after the food is aged, there will be more nutrients, better color and aroma, and the quality will be improved, and the stability and economic value of the food will be increased. The oxidation of ethanol is significantly strengthened, the ester components are increased, and the ar...
