Description

Intelligent constant temperature tea brewing machine and tea brewing method

The invention relates to an intelligent constant temperature tea brewing machine and a tea brewing method.

Tea drinking is part of traditional culture, and proper tea drinking can help with metabolism and is refreshing. There are many types of tea, such as Chinese green tea, white tea, yellow tea, green tea, black tea, black tea, flower tea, Japanese tea sencha, tea, matcha, powdered tea, fragrant tea, tea, black rice tea, etc. In addition, the black tea is divided into areas such as Darjeeling tea, Sri Lanka tea, etc. Because of the different teas, the temperature of the brewing water is not the same. The tea water temperature must be controlled according to the characteristics of the tea to make the color, fragrance and taste of the tea fully exerted. For example, the suitable water temperature of green tea is about 75 ° C ~ 80 ° C. In order to prevent high temperature, the aromatic substances of green tea are quickly evaporated and lost; white tea and yellow tea are suitable for water temperature of about 80 ° C ~ 85 ° C; green tea is suitable for water temperature of about 90 ° C ~ 95 ° C; flower tea is suitable for water temperature of about 85 ° C Black tea and black tea are suitable for water temperature of about 95 ° C ~ 100 ° C, water temperature control is not appropriate, will significantly reduce the taste and aroma of drinking. The tea water temperature must be controlled according to the characteristics of the tea to make the color, fragrance and taste of the tea fully exerted.
