殺(sha)青(qing)主(zhu)要目的(de)是通過(guo)高(gao)溫(wen)破壞和鈍化鮮(xian)葉中(zhong)(zhong)的(de)氧化酶(mei)活(huo)性，抑制鮮(xian)葉中(zhong)(zhong)的(de)茶多酚等的(de)酶(mei)促氧化，防止(zhi)烘干過(guo)程中(zhong)(zhong)變色。同時(shi)散發青(qing)臭味，促進良好(hao)香氣的(de)形成。殺(sha)青(qing)機(ji)械多采用微(wei)波殺(sha)青(qing)機(ji)、滾(gun)筒殺(sha)青(qing)機(ji)和燃氣炒青(qing)機(ji)。

微波殺青機

微(wei)波殺(sha)(sha)青(qing)設備(bei)是一種(zhong)新型的(de)殺(sha)(sha)青(qing)設備(bei)，殺(sha)(sha)青(qing)速(su)(su)度快(kuai)、效率(lv)高(gao)、效果好。在(zai)殺(sha)(sha)青(qing)的(de)同時，還(huan)可以除去(qu)約10%的(de)鮮(xian)葉(xie)(xie)水分。微(wei)波殺(sha)(sha)青(qing)機的(de)原理主(zhu)要是利用迅(xun)速(su)(su)升溫(wen)來(lai)鈍(dun)化(hua)鮮(xian)葉(xie)(xie)的(de)的(de)活性(xing)氧化(hua)酶，抑(yi)制鮮(xian)葉(xie)(xie)中的(de)茶(cha)多酚(fen)等酶加(jia)速(su)(su)氧化(hua)，防止在(zai)后續烘干過程中發生色(se)澤嚴重改(gai)變，同時揮(hui)發鮮(xian)葉(xie)(xie)的(de)腥草味，使茶(cha)香更(geng)好的(de)形(xing)成。采用微(wei)波殺(sha)(sha)青(qing)設備(bei)對茶(cha)葉(xie)(xie)、菊花、金銀花等農產品(pin)(pin)進行殺(sha)(sha)青(qing)，平均每公斤的(de)量所需要的(de)電費不到(dao)三毛(mao)錢，而且殺(sha)(sha)青(qing)效果顯著(zhu)，產品(pin)(pin)色(se)澤、外形(xing)和香氣都屬上佳品(pin)(pin)。
