目前，市場上流行的殺青機械多是以微波殺青(qing)機、滾筒殺青(qing)機和(he)燃氣炒青(qing)機為主。
1.微波殺青(qing)機
微波殺青(qing)(qing)設(she)備(bei)是一種(zhong)新型的(de)(de)殺青(qing)(qing)設(she)備(bei)，殺青(qing)(qing)速(su)(su)度快、效率(lv)高、效果好。在(zai)殺青(qing)(qing)的(de)(de)同時(shi)，還可以除(chu)去(qu)約10%的(de)(de)鮮葉(xie)水分。的(de)(de)原理主要是利用(yong)迅(xun)速(su)(su)升溫來鈍化鮮葉(xie)的(de)(de)的(de)(de)活性氧(yang)化酶(mei)，抑制鮮葉(xie)中的(de)(de)茶(cha)多酚等(deng)酶(mei)加(jia)速(su)(su)氧(yang)化，防止在(zai)后續(xu)烘干過程(cheng)中發生色澤嚴重改變，同時(shi)揮(hui)發鮮葉(xie)的(de)(de)腥草味，使茶(cha)香更好的(de)(de)形成。
采用微波殺(sha)青設(she)備(bei)對茶葉、菊花(hua)、金銀花(hua)等(deng)農產品進行殺(sha)青，平均每公斤的量(liang)所需(xu)要的電費不(bu)到三毛錢，而且(qie)殺(sha)青效果顯(xian)著(zhu)，產品色澤、外(wai)形和香氣(qi)都屬(shu)上佳品。
2.滾筒(tong)殺青機
烏(wu)龍(long)茶殺青常(chang)用90型與110型兩種(zhong)機(ji)型，該機(ji)結構(gou)緊湊、操作方便、效率高。爐火直接加熱轉動的筒
體(ti)，茶(cha)葉(xie)(xie)(xie)(xie)在筒(tong)(tong)(tong)(tong)體(ti)內靠摩擦和筒(tong)(tong)(tong)(tong)體(ti)轉(zhuan)動的(de)(de)離心力(li)在滾(gun)筒(tong)(tong)(tong)(tong)內拋(pao)轉(zhuan)，并吸收(shou)熱(re)量達到殺(sha)(sha)青目(mu)的(de)(de)。殺(sha)(sha)青適度后，反轉(zhuan)滾(gun)筒(tong)(tong)(tong)(tong)，利用(yong)(yong)筒(tong)(tong)(tong)(tong)壁(bi)的(de)(de)螺(luo)旋導(dao)葉(xie)(xie)(xie)(xie)板將茶(cha)葉(xie)(xie)(xie)(xie)推(tui)出(chu)筒(tong)(tong)(tong)(tong)外。同時，借助(zhu)(zhu)滾(gun)筒(tong)(tong)(tong)(tong)末端的(de)(de)風(feng)扇(shan)將筒(tong)(tong)(tong)(tong)內茶(cha)葉(xie)(xie)(xie)(xie)排(pai)凈。該機(ji)由滾(gun)筒(tong)(tong)(tong)(tong)、傳動裝置、風(feng)扇(shan)、機(ji)架、爐(lu)(lu)(lu)灶(zao)(zao)等部分組(zu)(zu)成(cheng)。滾(gun)筒(tong)(tong)(tong)(tong)用(yong)(yong)鋼板卷(juan)制而(er)成(cheng)，內壁(bi)焊有導(dao)葉(xie)(xie)(xie)(xie)板，導(dao)葉(xie)(xie)(xie)(xie)角為24°，其作用(yong)(yong)是幫助(zhu)(zhu)進葉(xie)(xie)(xie)(xie)或推(tui)出(chu)殺(sha)(sha)青葉(xie)(xie)(xie)(xie)，并將茶(cha)葉(xie)(xie)(xie)(xie)帶至一定高度后拋(pao)下。風(feng)扇(shan)可(ke)正、反轉(zhuan)，以吹葉(xie)(xie)(xie)(xie)出(chu)筒(tong)(tong)(tong)(tong)或吸排(pai)濕(shi)氣。滾(gun)筒(tong)(tong)(tong)(tong)的(de)(de)兩端外圍設有擋煙(yan)圈，中心有一轉(zhuan)軸，通(tong)過(guo)兩端的(de)(de)輻條與(yu)筒(tong)(tong)(tong)(tong)體(ti)相(xiang)接，轉(zhuan)軸由軸承(cheng)支撐于機(ji)架上。機(ji)架一般(ban)用(yong)(yong)角鋼制作。爐(lu)(lu)(lu)灶(zao)(zao)由通(tong)風(feng)道、爐(lu)(lu)(lu)柵、爐(lu)(lu)(lu)膛(tang)(tang)、煙(yan)囪等組(zu)(zu)成(cheng)。滾(gun)筒(tong)(tong)(tong)(tong)體(ti)置于爐(lu)(lu)(lu)膛(tang)(tang)內，爐(lu)(lu)(lu)膛(tang)(tang)頂部有拔風(feng)口與(yu)煙(yan)囪相(xiang)通(tong)。110型殺(sha)(sha)青機(ji)傳動配用(yong)(yong)功率(lv)(lv)1.1kW，投葉(xie)(xie)(xie)(xie)量15~25kg,風(feng)機(ji)功率(lv)(lv)0.75kW。
3.燃氣炒青機
該機(ji)以液(ye)化(hua)氣(qi)(qi)為(wei)(wei)熱(re)(re)(re)源，作(zuo)(zuo)(zuo)(zuo)業(ye)穩定，殺青均勻，清潔(jie)衛生、操作(zuo)(zuo)(zuo)(zuo)方便。該機(ji)為(wei)(wei)滾筒(tong)式，由滾筒(tong)、火(huo)(huo)(huo)排(pai)加熱(re)(re)(re)系統(tong)(tong)、傳(chuan)(chuan)動(dong)機(ji)構(gou)、出茶(cha)裝置、控(kong)制(zhi)(zhi)系統(tong)(tong)和機(ji)架組(zu)成(圖(tu)4)。滾筒(tong)體(ti)中部(bu)為(wei)(wei)圓筒(tong)式結構(gou)，兩(liang)端(duan)為(wei)(wei)150mm錐體(ti)，外筒(tong)體(ti)采用(yong)保溫材(cai)料，轉(zhuan)筒(tong)體(ti)下(xia)(xia)部(bu)敞開(kai)，用(yong)于安裝加熱(re)(re)(re)火(huo)(huo)(huo)排(pai);加熱(re)(re)(re)系統(tong)(tong)使用(yong)液(ye)化(hua)氣(qi)(qi)作(zuo)(zuo)(zuo)(zuo)燃料，燃燒器(qi)為(wei)(wei)直線排(pai)火(huo)(huo)(huo)式，采用(yong)電子(zi)點火(huo)(huo)(huo)裝置;傳(chuan)(chuan)動(dong)機(ji)構(gou)由無級(ji)變速(su)電機(ji)通過減速(su)裝置帶動(dong)筒(tong)體(ti)轉(zhuan)動(dong);機(ji)架用(yong)型鋼焊制(zhi)(zhi)。機(ji)器(qi)的所有結構(gou)均裝置于機(ji)架上，機(ji)架底部(bu)裝有4只(zhi)行(xing)走(zou)輪(lun)，便于移動(dong)。整機(ji)配用(yong)功(gong)率(lv)0.75kW，單機(ji)投葉(xie)量10~15kg。作(zuo)(zuo)(zuo)(zuo)業(ye)時(shi)，待筒(tong)內(nei)溫度(du)達到作(zuo)(zuo)(zuo)(zuo)業(ye)要求后，將(jiang)茶(cha)葉(xie)喂入滾筒(tong)內(nei)，通過控(kong)制(zhi)(zhi)系統(tong)(tong)調節滾筒(tong)轉(zhuan)速(su)及筒(tong)內(nei)溫度(du)，至茶(cha)葉(xie)殺青適度(du)時(shi)，讓筒(tong)體(ti)出葉(xie)端(duan)向(xiang)下(xia)(xia)傾斜，利用(yong)重力將(jiang)茶(cha)葉(xie)排(pai)出機(ji)外。
