[0003] At present, the State Intellectual Property Office has published an invention patent with a patent number of 201210539508.X "A Production Method for Tea Tree Flowers", which introduces a kind of tea tree flower through withering, steaming and killing, dehydration drying, drying and spreading and cooling. Fragrance process, the shortcoming of this invention is: 1, the time of steaming and steaming is long, the water content of the tea tree flower after finishing is high, and the flowers are easy to stick to each other, which affects the appearance. The loss of contained substances will affect the quality of tea tree flowers; 2. If the drying temperature is too high, it will destroy the chemical bonds of tea tree flower elements and increase its loss;
[0004] The invention patent of CN103598368 A "a processing method of tea tree flower" discloses a tea tree flower finished product including picking, withering, fixing, high-temperature dehydration, sub-sieving, baking, cooling, and low-temperature drying. The above-mentioned fixing time is too long, the high temperature dehydration temperature is high, and the time is long, which will destroy the chemical bonds of tea tree flower elements and increase its loss;

Embodiment 1

[0020] Pick the tea tree flowers in the bud stage after the dew has dried up. The residual flowers and rotten flowers are not picked. Spread them on a clean water sieve, bamboo mat, or wooden board with a thickness of 2-3cm, and naturally wither indoors at 25-30°C for 4-6 hours. Evenly spread a single layer of tea tree flowers on the conveyor belt of a tea microwave curing machine with a microwave frequency of 2450±10MHz and a power of 6KW (produced and commercially available by Nanjing Aorun Microwave Technology Co., Ltd.), and adjust the continuously variable speed regulator to F=8 , the transmission speed is 0.76 m / min, and the greening time is 3 minutes and 40 seconds. After the microwave curing, the water content of the tea tree tea reaches 45%. Dehydration and drying in the tea roaster, drying temperature 90-95°C, drying time 1 hour, naturally cool to 20-30°C, then bake at 85°C for 2 hours, take out when the water content is lower than 6%, spread and cool to 20 After ~30...

Embodiment 2

[0022] Pick the tea tree flowers in the bud stage after the dew has dried up. The residual flowers and rotten flowers are not picked. Spread them on a clean water sieve, bamboo mat, or wooden board with a thickness of 2-3cm, and naturally wither indoors at 25-30°C for 4-6 hours. Evenly spread a single layer of tea tree flowers on the conveyor belt of a tea microwave curing machine with a microwave frequency of 2450±10MHz and a power of 6KW (produced and commercially available by Nanjing Aorun Microwave Technology Co., Ltd.), and adjust the continuously variable speed regulator to F=9 , the transmission speed is 0.83 m / min, and the greening time is 3 minutes and 20 seconds. After the microwave curing, the water content of the tea tree tea reaches 50%. Dehydration and drying in the tea roaster, drying temperature 90-95°C, drying time 1.5 hours, natural cooling to 20-30°C and then drying at 85°C for 2 hours, take out when the water content is lower than 6%, spread and cool to Aft...

Embodiment 3

[0024] Pick the tea tree flowers in the opening stage after the dew has dried up. The residual flowers and rotten flowers are not picked. Spread them on a clean water sieve, bamboo mat, or wooden board with a thickness of 2 to 3 cm. Naturally wither indoors at 25 to 30 ° C for 4 to 6 hours. Evenly spread a single layer of tea tree flowers on the conveyor belt of a tea microwave curing machine with a microwave frequency of 2450±10MHz and a power of 6KW (produced and commercially available by Nanjing Aorun Microwave Technology Co., Ltd.), and adjust the continuously variable speed regulator to F=10 , the transmission speed is 0.90 m / min, and the greening time is 3 minutes and 5 seconds. After the microwave curing, the water content of the tea tree tea reaches 45%, and the tea tree flowers after cooling to 20-30°C are spread in a single layer on the tray, and placed Dehydrate and dry in the tea roaster, drying temperature 85-90°C, drying time 0.5 hours, naturally cool to 20-30°C a...

Abstract

The invention relates to a processing method for tea flowers. The processing method comprises the following steps: picking the tea flowers, withering, carrying out fixation, drying and packaging. According to the method, a microwave water removing machine is utilized for rapidly finish fixation in short time; meanwhile, in a fixation process, a lot of water molecules are escaped and evaporated from the tea flowers so as to realize the primary drying aim; the color, the flavor, the shape and the taste of the fresh tea flowers can keep unchanged to the greatest extent and effective substances are kept to the greatest extent; the high-aroma and the high-quality tea flowers are prepared.

Description

technical field [0001] The invention relates to a method for processing tea tree flowers, and belongs to the technical field of new resource beverage processing. Background technique [0002] Tea tree placenta is known as tea tree placenta. It has the same nutritional and health value as tea. It contains a variety of active ingredients and active substances. Nourishing and other effects.
