EXTRACTION METHOD OF TEA WATER WITH PRESSURIZED WATER VAPOR

摘要

An extraction method of tea water with pressurized water vapor is disclosed, which comprises baking tea leaves and extracting tea water with pressurized water vapor. The tea water is obtained by increasing pressure to adjust the temperature of water vapor and letting the water vapor pass through temperature-adjusted tea leaves. The method maintains the temperature characteristics of the tea and improves dissolving out of trace elements from tea leaves. The tea water obtained has appearance of pure color and tea infusion is translucent. The method improves color stability and cold solubility of the tea infusion, improves color of the instant tea products, and can be widely used in all kinds of tea beverage and on-site tea rooms. The method can increase parameter consistency of the produced tea infusion caused by heat, overcome the shortcomings of lack of taste by long time steeping of the tea and of drinking excessive water when people change the tea species, and reform the preparation method of tea beverage and the method of tasting tea. The raw materials of making tea beverage in the present invention can be old tea leaves and tea dust. Hence, it can improve the production efficiency of tea farmers indirectly and improve the quality and grade of the tea leaves. The present invention belongs to the field of the tea leaves processing and tea beverage.
