林語堂說,春天要做三件事,“賞花,踏青,喝西湖龍井”,時下正值龍井茶季,清明前到谷雨后,是享譽千年的西湖龍井在一年中最重要也最熱鬧的時節(jié)。茶芽已不再羞澀,大大方方伸展出鑲了黃邊的嫩葉,等待采摘。自《茶經》記載以來,龍井茶從未阻斷煙火,遠離人間,歷代文人騷客亦不吝留下詩文。
茶文化在我國是傳統(tǒng)文化之一,也擁有著悠久的歷史,在我國茶葉已有一千多年的歷史了。在茶葉生產量方面我國一直居世界首位,但是茶葉出口量卻一直排在斯里蘭卡和肯尼亞之后,靠后的主要原因就是我國茶葉中的農藥殘留超標嚴重,中國的茶葉質量標準遠遠低于其他發(fā)達國家。
為保證出口茶葉的高品質,中國各區(qū)域茶研究院在茶葉品種及品質方面也一直在做研究。在樣品制備方面,傳統(tǒng)的機械研磨粉碎不均勻效果并不好,上海凈信公司出品的全能型行星式球磨機就比較適合茶葉研磨。
這款儀器適合堅硬、中等硬度、脆性和纖維材料的濕法及干法粉碎和細化,出樣細度可小于100nm,亦可用于懸浮液中固體的研磨、樣品混合和均一化處理以及金屬合金化等。樣品處理量12000ml,可同時放置4個體積為3000ml的球磨罐使用,球磨罐材質有十余種提供選擇。運用創(chuàng)新的齒輪降噪技術和全封閉式噪聲隔離設計來控制運行噪聲,有效提升實驗室使用的舒適性,高效率的樣品處理能力、獨特的外觀和結構設計、嚴格的生產工藝助力。
