Tea brewing apparatus |
摘要 |
Tea making apparatus of the type comprising of the means for supplying heated water over a basket for holding a bed of tea leaves. In accordance with the invention a syphon tube is provided to delay the passage of hot water through the tea leaf bed until the hot water reaches a pre-determined level so that the hot water is in contact with the tea leaves for a period in excess of one minute before discharge. The inlet arm of the syphon tube has a roughened inner surface to maintain droplets of brewed tea therein, following discharge of the brew from the tea leaf bed, the droplets serving to aid the start of a secondary syphon on accumulation of brewed tea above the level of the syphon inlet. Thus after the initial brew, water remains in contact with the tea leaf bed for only a short time so that the leaves do not become oversoaked.
