Embodiment 1

[0026] A processing method for keeping green tea fresh at room temperature, comprising the following steps:

[0027] A: Cleaning: Wash the freshly picked green tea leaves in clean water, and drain the water for later use;

[0028] B: Sterilization: use 60Co-γ rays to sterilize green tea leaves by radiation;

[0029] C: Drying: Put the semi-finished green tea that has been greened and kneaded into a microwave drying equipment for drying treatment. During this process, the green tea is evenly spread on the conveyor belt of the microwave equipment in a single layer. The speed of the microwave equipment is 600 rpm. / min, the output power is 6KW, the drying temperature is 260°C, and the drying time is 5 minutes;

[0030] D: Quenching processing: Send the high-temperature tea leaves after microwave curing directly into the quenching machine for quenching processing, and then check the moisture content. When the moisture exceeds 3%, repeat the above step C until the moisture content...

Embodiment 2

[0034] A processing method for keeping green tea fresh at room temperature, comprising the following steps:

[0035] A: Cleaning: Wash the freshly picked green tea leaves in clean water, and drain the water for later use;

[0036] B: Sterilization: use 60Co-γ rays to sterilize green tea leaves by radiation;

[0038] D: Quenching processing: Send the high-temperature tea leaves after microwave curing directly into the quenching machine for quenching processing, and then check the moisture content. When the moisture exceeds 3%, repeat the above step C until the moistur...

Embodiment 3

[0042] A processing method for keeping green tea fresh at room temperature, comprising the following steps:

[0043] A: Cleaning: Wash the freshly picked green tea leaves in clean water, and drain the water for later use;

[0044] B: Sterilization: use 60Co-γ rays to sterilize green tea leaves by radiation;

[0045] C: Drying: Put the semi-finished green tea that has been greened and kneaded into a microwave drying equipment for drying treatment. During this process, the green tea is evenly spread on the conveyor belt of the microwave equipment in a single layer. The rotation speed of the microwave equipment is 800 rpm. / min, the output power is 7KW, the drying temperature is 300°C, and the drying time is 6 minutes;

Abstract

The invention discloses a processing method of green tea for preservation at room temperature, and relates to the technical field of green tea processing. The processing method includes the followingsteps: A conducting cleaning; B. conducting sterilizing; C. conducting drying; D. conducting quenching processing; E. coducting ventilating and F. conducting packaging. The processing method solves the problem that tea leaves are easy to oxidize and deteriorate during storage, and enables tea leaves to be preserved at room temperature for a long time. In the invention, a nano material packaging bag is used for oxygen-blocking packaging, so that green tea leaves are airtight, opaque and watertight, and loss of the aroma component in green teas and taint of odor are avoided. Ultraviolet irradiation treatment after packaging causes allosteric inactivation of oxidases to prevent oxidation of active ingredients in green tea. The processing method can preserve the flavor, microelements and vitamins of new tea for a long time, thereby greatly improving taste and economic benefits of green teas.

Description

technical field [0001] The invention relates to the technical field of green tea processing, in particular to a processing method for keeping green tea fresh at room temperature. Background technique [0002] Green tea contains tea polyphenols, caffeine, chlorophyll, and vitamins. It has been confirmed by modern scientific research that green tea contains more than 450 organic compounds and more than 15 inorganic minerals. Most of these ingredients have health care and disease prevention effects. It has special effects on anti-aging, anti-cancer, anti-cancer, sterilization, anti-inflammatory, etc., which is inferior to other teas. Green tea is because of its important position in production and life and its own multiple health benefits. [0003] With the improvement of people's quality of life, the enhancement of health care awareness and the increase of demand for famous and high-quality products, the output and output value of green tea are increasing year by year. Howev...
