摘要
利用高频率振动源,使青叶轻、快、匀地摩擦碰撞,叶缘细胞适度损伤和茶多酚酶促氧化。振动摇青的生产率比手工摇青提高3一4倍,相当于滚筒摇青机生产率的65%一80%,但其做青质量和毛茶品质均比滚筒摇青有显著提高,而接近手工摇青。
By using high frequency mechanical vibration,the slight,brisk and even friction and collision betweenwithered leaves could be achieved in the rocking process, resulting in the proper injury of the leaf margin tis-sue and the oxidation of polyphenols. The rocking by mechanical vibration got 4一5times productivity as thatby the orthodox method, or 65%一80%as that by the rolling rocking machines. The vibration rocking pro-duced much better quality of Oolong Tea than the rolling rocking, or similar quality as the orthodox rocking.
