Embodiment 1

[0027] The anti-fouling aging method of the present invention for placing black tea in a packaging container with air-permeable exhaust valves with sealing and filtering membranes includes the following steps:

[0028] a) Pack the black tea in a packaging container equipped with a ventilating valve, and keep the packaging container closed;

[0029] b) The breathable exhaust valve includes a breathable valve and an exhaust valve. Tighten the first adjusting and protective cover of the breathable valve to keep the breathable valve in an airtight and airtight state;

[0030] c) Unscrew the cover of the air extraction valve installed on the packaging container, and use the prepared vacuum pump to align the air extraction pipe port with the air extraction hole of the air extraction valve to extract air through the elastic deformation of the sealing sheet to make the vacuum degree in the packaging container Reach ≤150~250Pa, and also minimize the air in the packaging container and the dust...

Embodiment 2

[0047] The anti-fouling aging method of the present invention for placing black tea in a packaging container with air-permeable exhaust valves with sealing and filtering membranes includes the following steps:

[0048] e) Pack the black tea in a packaging container with a ventilating valve, and keep the packaging container closed;

[0049] f) Unscrew the protective cover of the vent valve installed on the packaging container, activate the vent valve form of the vent valve, use the prepared vacuum pump to align the port of the vent pipe to the vent hole of the pump through the sealing film The elastic deformation of the packaging container is used for air extraction, so that the vacuum degree in the packaging container can reach ≤150~250Pa, and the air in the packaging container and the dust particles and microorganisms it carries are reduced to a minimum. There is very little residual air. Seal the air extraction hole immediately with a sealing strip ;

[0050] g) Use the bag body i...

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 invention relates to a tea packaging, storage and aging method and its special device, in particular to an anti-fouling aging method and its implementation for placing black tea in a packaging container with a sealing and filtering membrane air-permeable exhaust valve Packaging container specially designed for the above method. Background technique [0002] Food aging, or aging, generally refers to the state in which the quality of food changes over time during storage. If the quality develops in the direction of degradation and deterioration, it is generally called aging deterioration, such as the aging deterioration of rice. If the food has more nutrients, better color, fragrance, and quality after aging, it will increase the stability and economic value of the food, it is especially called post-ageing, such as wine after aging. The alcohol oxidation effect is significantly strengthened, the ester composition is increased, and the wine aroma is more...
