Dark tea bag preparation method

Abstract

The invention discloses a dark tea bag preparation method in which non-pressed initial-processed dark tea in bulk or fine-processed dark tea in bulk is taken as raw material tea to process tea bags. The method comprises the specific steps of 1 purifying, wherein tea leaves are humidified with purified water until the tea leaves absorb water to be saturate, the humidified tea leaves are placed in a vacuum environment to be dried by applying microwaves until the moisture content is smaller than or equal to 10%, and the steps are repeatedly performed for several times; 2 air separating and screening on the tea leaves; 3 smashing and screening; 4 blending and even heaping; 5 sterilizing, wherein the tea leaves are wet with the purified water, the wet tea leaves are placed in the vacuum environment in time to be sterilized and dried by applying the microwaves, and the steps are performed for at least one time; 6 baking, wherein the tea leaves are baked until the moisture content is smaller than or equal to 6%; 7 packaging, wherein the finished tea bags are obtained. According to the method, on the premise that the existing fragrance, taste and quality of the tea leaves are not damaged, thorough purifying on the insides and outsides of the tea leaves is achieved, and the hygiene and safety of the tea bags are guaranteed.

Description

technical field [0001] The invention relates to a method for preparing black tea bagged tea. Background technique [0002] Since it was invented at the beginning of the 20th century, teabags have been occupying an important position in the entire tea consumption with its advantages of "quantitative, hygienic, convenient and fast". [0003] The processing of teabags usually goes through processes from raw materials to finished products: sterilization, crushing, screening, blending, heaping, drying, sterilization, packaging and other processes. Some of the raw materials use primary processed tea, and some use refined processed tea. [0004] Because tea is easy to breed microorganisms when the temperature and humidity are appropriate, the raw tea is first sterilized when processing teabags, and then sterilized again before packaging, and it is required that hands are not allowed to touch the tea leaves and the inner packaging of teabags during the entire process The purpose is...

Problems solved by technology

[0005] However, since the fresh leaves of black tea are directly processed after picking, the primary or refined tea will inevitably be covered with pollutants such as dust, insect eggs, bird and animal feces, and there will be dirt on the surface of the tea and inside the tea. Pesticide residues, these pollutants and pesticide residues from planting technology, planting environment, etc. can not be effectively removed only through wind selection, screening, sterilization and other existing teabag processes. These pollutants and pesticide residues still threaten drinking patient's health
