Processing method for tea flowers

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.

[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. At the same time, the camellia powder in the tea tree flower has high protein and low fat; it is rich in vitamin A, vitamin D, vitamin B2 and other vitamins; it contains high activity of superoxide dismutase (SOD) and catalase (CAT); It contains a complete range of amino acids, high proline content, the total amount of hydrolyzed essential amino acids and free amino acids is higher than other natural pollen; high flavonoid content and other characteristics. Camellia japonica is a kind of potential resource with great development value and broad development prospect. At present, the qualit...

Examples

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...

[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...

[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...
