目前，市場上流行的殺青機械多是以微波殺(sha)青機(ji)、滾筒殺(sha)青機(ji)和燃氣炒青機(ji)為主(zhu)。
1.微波殺青機(ji)
微波(bo)殺(sha)青設(she)備是一種(zhong)新型(xing)的(de)(de)殺(sha)青設(she)備，殺(sha)青速(su)度快、效率高(gao)、效果(guo)好(hao)。在(zai)殺(sha)青的(de)(de)同時(shi)，還可以(yi)除去約10%的(de)(de)鮮(xian)(xian)葉(xie)水分。的(de)(de)原(yuan)理主(zhu)要是利用迅速(su)升(sheng)溫來鈍化(hua)鮮(xian)(xian)葉(xie)的(de)(de)的(de)(de)活性氧(yang)化(hua)酶，抑制鮮(xian)(xian)葉(xie)中的(de)(de)茶多(duo)酚等酶加速(su)氧(yang)化(hua)，防止在(zai)后續烘(hong)干(gan)過(guo)程中發生色(se)澤嚴重改變(bian)，同時(shi)揮發鮮(xian)(xian)葉(xie)的(de)(de)腥草味，使茶香更好(hao)的(de)(de)形成(cheng)。
采(cai)用微波殺青設(she)備對茶葉、菊花、金銀花等農產品進(jin)行殺青，平均每公斤的(de)(de)量所需(xu)要的(de)(de)電費不到三(san)毛錢(qian)，而且(qie)殺青效果顯(xian)著(zhu)，產品色澤、外形和香氣(qi)都屬上(shang)佳(jia)品。
2.滾筒殺青機
烏龍茶殺青常用(yong)90型(xing)與110型(xing)兩(liang)種機型(xing)，該機結構(gou)緊湊、操(cao)作方(fang)便、效率(lv)高(gao)。爐火直接(jie)加熱轉動(dong)的(de)筒
體(ti)，茶(cha)(cha)葉(xie)(xie)在筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)體(ti)內(nei)靠摩擦和筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)體(ti)轉動的離(li)心力在滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)內(nei)拋轉，并(bing)吸收熱量達到(dao)殺青目的。殺青適度后(hou)，反轉滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)，利(li)用(yong)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)壁的螺旋導葉(xie)(xie)板(ban)將茶(cha)(cha)葉(xie)(xie)推出筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)外。同時，借助(zhu)(zhu)滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)末端的風扇將筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)內(nei)茶(cha)(cha)葉(xie)(xie)排(pai)凈。該機(ji)(ji)由滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)、傳動裝(zhuang)置(zhi)、風扇、機(ji)(ji)架(jia)(jia)、爐(lu)灶等(deng)部(bu)分組成。滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)用(yong)鋼板(ban)卷制而成，內(nei)壁焊有(you)導葉(xie)(xie)板(ban)，導葉(xie)(xie)角為24°，其作(zuo)用(yong)是(shi)幫助(zhu)(zhu)進葉(xie)(xie)或推出殺青葉(xie)(xie)，并(bing)將茶(cha)(cha)葉(xie)(xie)帶至一(yi)定高(gao)度后(hou)拋下。風扇可正、反轉，以吹葉(xie)(xie)出筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)或吸排(pai)濕氣。滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)的兩端外圍設(she)有(you)擋(dang)煙圈，中(zhong)心有(you)一(yi)轉軸(zhou)，通(tong)過兩端的輻條與筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)體(ti)相接，轉軸(zhou)由軸(zhou)承支撐于機(ji)(ji)架(jia)(jia)上。機(ji)(ji)架(jia)(jia)一(yi)般用(yong)角鋼制作(zuo)。爐(lu)灶由通(tong)風道(dao)、爐(lu)柵、爐(lu)膛(tang)(tang)、煙囪等(deng)組成。滾(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)(tong)(tong)體(ti)置(zhi)于爐(lu)膛(tang)(tang)內(nei)，爐(lu)膛(tang)(tang)頂部(bu)有(you)拔風口與煙囪相通(tong)。110型殺青機(ji)(ji)傳動配用(yong)功率(lv)1.1kW，投(tou)葉(xie)(xie)量15~25kg,風機(ji)(ji)功率(lv)0.75kW。
3.燃氣炒青(qing)機
該(gai)機(ji)(ji)以液(ye)化氣為(wei)熱源，作業(ye)穩定，殺(sha)青(qing)均勻(yun)，清(qing)潔衛生、操作方便。該(gai)機(ji)(ji)為(wei)滾(gun)筒(tong)式，由(you)滾(gun)筒(tong)、火排加(jia)(jia)熱系(xi)統、傳動(dong)(dong)(dong)機(ji)(ji)構、出茶(cha)裝(zhuang)(zhuang)置(zhi)、控制(zhi)(zhi)系(xi)統和(he)機(ji)(ji)架組成(圖4)。滾(gun)筒(tong)體中部(bu)為(wei)圓筒(tong)式結構，兩端(duan)為(wei)150mm錐體，外筒(tong)體采(cai)用保溫材料，轉筒(tong)體下(xia)部(bu)敞開，用于安裝(zhuang)(zhuang)加(jia)(jia)熱火排;加(jia)(jia)熱系(xi)統使用液(ye)化氣作燃料，燃燒(shao)器為(wei)直線排火式，采(cai)用電子點火裝(zhuang)(zhuang)置(zhi);傳動(dong)(dong)(dong)機(ji)(ji)構由(you)無(wu)級變(bian)速(su)(su)電機(ji)(ji)通(tong)過減速(su)(su)裝(zhuang)(zhuang)置(zhi)帶(dai)動(dong)(dong)(dong)筒(tong)體轉動(dong)(dong)(dong);機(ji)(ji)架用型鋼焊(han)制(zhi)(zhi)。機(ji)(ji)器的所有(you)結構均裝(zhuang)(zhuang)置(zhi)于機(ji)(ji)架上，機(ji)(ji)架底(di)部(bu)裝(zhuang)(zhuang)有(you)4只(zhi)行走輪，便于移動(dong)(dong)(dong)。整機(ji)(ji)配用功(gong)率(lv)0.75kW，單機(ji)(ji)投(tou)葉量(liang)10~15kg。作業(ye)時，待筒(tong)內溫度(du)達到(dao)作業(ye)要求后，將茶(cha)葉喂入滾(gun)筒(tong)內，通(tong)過控制(zhi)(zhi)系(xi)統調節滾(gun)筒(tong)轉速(su)(su)及筒(tong)內溫度(du)，至茶(cha)葉殺(sha)青(qing)適(shi)度(du)時，讓筒(tong)體出葉端(duan)向下(xia)傾(qing)斜，利(li)用重力將茶(cha)葉排出機(ji)(ji)外。
