Make 1*10 8 ~5*10 8 golden flower bacteria liquid per ml, the golden flower bacterial liquid is a bacterial suspension made by scraping and purifying strains with sterile water, counted and inoculated in the treated loose tea with a hemocytometer, and the inoculum amount is 80% relative to dry tea. ~120ml / kg, culture time 3~5 days, culture temperature 24~30℃, humidity 60%~70%, until the surface of loose tea is covered with golden flowers; microwave drying, microwave dehydration efficiency is calculated as 0.8~1kg / kW / hou...

Embodiment 1

[0047] An automated fermentation process for chrysanthemum tea, comprising the following steps:

[0048] 1) Preparation of golden flower fungus tea powder:

[0049] a. First isolate the golden flower fungus from the Fuzhuan brick tea, purify and identify it, and expand it on the PDA medium for further cultivation; wherein, the purification and identification is identification of morphological characteristics; the PDA medium is a potato dextrose agar medium.

[0050] b. Then loose tea treatment: 2kg of loose tea, spray treatment with normal temperature water, regain moisture for 2-3 hours until the water content is 25%-30%, microwave power 2000w, sterilize for 10s every 1min, sterilization time 3-5min; press whether the tea is pressed or not It can be divided into pressed tea and loose tea. Unpressed tea can be called loose tea, including unpressed Pu'er, black tea, black tea, green tea, green tea, yellow tea, etc. Loose tea is not pressed into flakes or clusters.

Abstract

The invention relates to a fermented tea automatic processing method, in particular to a eurotium cristatum tea processing method. The processing steps include: spraying to loose tea, moisture regain, microwave sterilization, inoculation, fungus-growing, and drying. The process provided by the invention realizes automatic fermentation of eurotium cristatum tea, has simple and automatic procedure, and solves the problem that the tea prepared by high pressure steam sterilization has moisture flavor. Also, the air introduced in the fermentation process is subjected to filtering treatment, the sundry bacteria contamination problem is effectively solved, the temperature is controlled at a temperature suitable for eurotium cristatum growth, thus being in favor of rapid growth of eurotium cristatum and effectively shortening the production cycle. Through fermentation for 3-5 days, eurotium cristatum tea covered with eurotium cristatum can be obtained.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to an automatic fermentation process of chrysanthemum tea. Background technique [0002] In recent years, Fuzhuan brick tea has been favored by consumers because of its unique quality characteristics and health benefits, and its unique golden flower fungus has become a hot spot for everyone's attention and research. Studies have shown that the growth of golden flowers in Fuzhuan significantly affects the changes in the content of tea leaves. During the flowering process of golden flower fungi, a series of metabolic enzymes, such as cellulase and polyphenol oxidase, are produced, which make the tea content Hydrolysis, transformation, oxidation, and polymerization take place to form a series of substances beneficial to the human body and improve the quality of tea. At the same time, the golden flower fungus itself has the effects of lipid-lowering, antibacterial, anti-tumor, anti-oxidat...
