Preparation method of yellow tea bag

Abstract

The invention discloses a preparation method of a yellow tea bag. The method adopts preliminarily processed yellow tea or finely processed yellow tea as the raw material tea to process the tea bag, and the specific steps include: 1. purification: 1.1 firstly humidifying tea to a saturated degree with solvent water, then placing the humidified tea in a vacuum environment, and applying microwave to dry the tea to a water content of less than or equal to 8%; 1.2 repeating step 1.1 several times; 2. tea winnowing and sieving; 3. crushing and screening; 4. blending and uniform piling; 5. sterilization: 5.1 firstly, wetting tea with purified water, then putting the wetted tea in a vacuum environment timely, applying microwave to conduct sterilization and performing drying; and 5.2 repeating step 5.1 at least once; 6. baking: baking tea to a water content of less than or equal to 6%; and 7. packaging, thus obtaining a tea bag finished product. Under the premise of not damaging the aroma, taste and quality already existing in tea, the method provided by the invention realizes thorough purification of the inside and outside of tea, and ensures the health and safety of the tea bag.

Description

technical field [0001] The invention relates to a method for preparing yellow tea teabags. 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 t...

Problems solved by technology

[0005] However, since the fresh leaves of yellow tea are picked and processed directly, dust, insect eggs, bird and animal feces and other pollutants will inevitably be attached to the primary or refined tea, and there will be dirt on the surface of the tea leaves and inside the tea leaves. 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 tea bag processes. These pollutants and pesticide residues still threaten drinking patient's health
