林语堂说,春天要做三件事,“赏花,踏青,喝西湖龙井”,时下正值龙井茶季,清明前到谷雨后,是享誉千年的西湖龙井在一年中最重要也最热闹的时节。茶芽已不再羞涩,大大方方伸展出镶了黄边的嫩叶,等待采摘。自《茶经》记载以来,龙井茶从未阻断烟火,远离人间,历代文人骚客亦不吝留下诗文。
茶文化在我国是传统文化之一,也拥有着悠久的历史,在我国茶叶已有一千多年的历史了。在茶叶生产量方面我国一直居世界首位,但是茶叶出口量却一直排在斯里兰卡和肯尼亚之后,靠后的主要原因就是我国茶叶中的农药残留超标严重,中国的茶叶质量标准远远低于其他发达国家。
为保证出口茶叶的高品质,中国各区域茶研究院在茶叶品种及品质方面也一直在做研究。在样品制备方面,传统的机械研磨粉碎不均匀效果并不好,上海净信公司出品的全能型行星式球磨机就比较适合茶叶研磨。
这款仪器适合坚硬、中等硬度、脆性和纤维材料的湿法及干法粉碎和细化,出样细度可小于100nm,亦可用于悬浮液中固体的研磨、样品混合和均一化处理以及金属合金化等。样品处理量12000ml,可同时放置4个体积为3000ml的球磨罐使用,球磨罐材质有十余种提供选择。运用创新的齿轮降噪技术和全封闭式噪声隔离设计来控制运行噪声,有效提升实验室使用的舒适性,高效率的样品处理能力、独特的外观和结构设计、严格的生产工艺助力。
