目前，市場上流行的殺青機械多是以微波殺(sha)青機(ji)、滾筒(tong)殺(sha)青機(ji)和燃氣炒青機(ji)為主。
1.微波(bo)殺青機(ji)
微(wei)波(bo)殺(sha)(sha)青(qing)設(she)備是(shi)一(yi)種(zhong)新型的(de)(de)殺(sha)(sha)青(qing)設(she)備，殺(sha)(sha)青(qing)速度快(kuai)、效率高、效果好(hao)。在殺(sha)(sha)青(qing)的(de)(de)同時，還可以除去(qu)約10%的(de)(de)鮮(xian)葉水(shui)分。的(de)(de)原理主(zhu)要是(shi)利用迅(xun)速升溫來鈍化(hua)(hua)鮮(xian)葉的(de)(de)的(de)(de)活性氧化(hua)(hua)酶(mei)，抑制鮮(xian)葉中的(de)(de)茶多酚等酶(mei)加速氧化(hua)(hua)，防止在后續烘干過程中發生色澤嚴重改變，同時揮發鮮(xian)葉的(de)(de)腥草味(wei)，使茶香更好(hao)的(de)(de)形成。
采用微波殺(sha)青設備對茶葉(xie)、菊花(hua)、金(jin)銀(yin)花(hua)等農產品進行殺(sha)青，平(ping)均每(mei)公斤的量(liang)所需要的電費(fei)不到(dao)三(san)毛錢，而且殺(sha)青效果顯著，產品色澤、外形(xing)和(he)香氣(qi)都屬上佳品。
2.滾筒殺青機
烏龍茶殺青常(chang)用90型(xing)與110型(xing)兩種(zhong)機型(xing)，該機結(jie)構緊湊、操(cao)作方便、效率高(gao)。爐(lu)火(huo)直接(jie)加熱轉動的筒
體，茶葉(xie)(xie)(xie)在筒(tong)(tong)體內(nei)(nei)(nei)靠摩擦和(he)筒(tong)(tong)體轉(zhuan)(zhuan)動(dong)的(de)(de)離心力在滾(gun)(gun)筒(tong)(tong)內(nei)(nei)(nei)拋轉(zhuan)(zhuan)，并吸收熱量(liang)達到殺(sha)青(qing)目的(de)(de)。殺(sha)青(qing)適度后，反(fan)轉(zhuan)(zhuan)滾(gun)(gun)筒(tong)(tong)，利用(yong)(yong)(yong)筒(tong)(tong)壁(bi)(bi)的(de)(de)螺旋導葉(xie)(xie)(xie)板(ban)將(jiang)茶葉(xie)(xie)(xie)推出筒(tong)(tong)外。同(tong)時，借助滾(gun)(gun)筒(tong)(tong)末端(duan)的(de)(de)風(feng)(feng)(feng)扇(shan)(shan)將(jiang)筒(tong)(tong)內(nei)(nei)(nei)茶葉(xie)(xie)(xie)排(pai)凈(jing)。該機(ji)(ji)(ji)(ji)由滾(gun)(gun)筒(tong)(tong)、傳動(dong)裝置、風(feng)(feng)(feng)扇(shan)(shan)、機(ji)(ji)(ji)(ji)架、爐(lu)灶等部分(fen)組成。滾(gun)(gun)筒(tong)(tong)用(yong)(yong)(yong)鋼(gang)板(ban)卷(juan)制而(er)成，內(nei)(nei)(nei)壁(bi)(bi)焊有(you)(you)導葉(xie)(xie)(xie)板(ban)，導葉(xie)(xie)(xie)角為(wei)24°，其作用(yong)(yong)(yong)是幫助進葉(xie)(xie)(xie)或(huo)(huo)推出殺(sha)青(qing)葉(xie)(xie)(xie)，并將(jiang)茶葉(xie)(xie)(xie)帶至一(yi)(yi)定高度后拋下。風(feng)(feng)(feng)扇(shan)(shan)可正、反(fan)轉(zhuan)(zhuan)，以吹(chui)葉(xie)(xie)(xie)出筒(tong)(tong)或(huo)(huo)吸排(pai)濕(shi)氣。滾(gun)(gun)筒(tong)(tong)的(de)(de)兩(liang)端(duan)外圍設有(you)(you)擋煙圈(quan)，中(zhong)心有(you)(you)一(yi)(yi)轉(zhuan)(zhuan)軸，通過兩(liang)端(duan)的(de)(de)輻條與筒(tong)(tong)體相接(jie)，轉(zhuan)(zhuan)軸由軸承支撐于機(ji)(ji)(ji)(ji)架上。機(ji)(ji)(ji)(ji)架一(yi)(yi)般用(yong)(yong)(yong)角鋼(gang)制作。爐(lu)灶由通風(feng)(feng)(feng)道(dao)、爐(lu)柵、爐(lu)膛、煙囪等組成。滾(gun)(gun)筒(tong)(tong)體置于爐(lu)膛內(nei)(nei)(nei)，爐(lu)膛頂(ding)部有(you)(you)拔風(feng)(feng)(feng)口(kou)與煙囪相通。110型殺(sha)青(qing)機(ji)(ji)(ji)(ji)傳動(dong)配用(yong)(yong)(yong)功率1.1kW，投葉(xie)(xie)(xie)量(liang)15~25kg,風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)功率0.75kW。
3.燃(ran)氣炒(chao)青機(ji)
該機(ji)(ji)以(yi)液(ye)化(hua)氣為熱(re)源，作(zuo)業穩定，殺(sha)青均勻，清潔衛生、操(cao)作(zuo)方便(bian)。該機(ji)(ji)為滾(gun)筒(tong)(tong)(tong)式，由(you)(you)滾(gun)筒(tong)(tong)(tong)、火(huo)排加(jia)熱(re)系統、傳動(dong)機(ji)(ji)構、出(chu)(chu)茶(cha)裝(zhuang)(zhuang)置、控制系統和機(ji)(ji)架組成(cheng)(圖4)。滾(gun)筒(tong)(tong)(tong)體(ti)(ti)(ti)(ti)(ti)中部為圓筒(tong)(tong)(tong)式結構，兩端為150mm錐(zhui)體(ti)(ti)(ti)(ti)(ti)，外筒(tong)(tong)(tong)體(ti)(ti)(ti)(ti)(ti)采(cai)(cai)用(yong)保溫材料(liao)，轉筒(tong)(tong)(tong)體(ti)(ti)(ti)(ti)(ti)下(xia)部敞(chang)開，用(yong)于(yu)(yu)安裝(zhuang)(zhuang)加(jia)熱(re)火(huo)排;加(jia)熱(re)系統使用(yong)液(ye)化(hua)氣作(zuo)燃(ran)料(liao)，燃(ran)燒器(qi)為直線排火(huo)式，采(cai)(cai)用(yong)電(dian)子點火(huo)裝(zhuang)(zhuang)置;傳動(dong)機(ji)(ji)構由(you)(you)無級變速電(dian)機(ji)(ji)通過(guo)減(jian)速裝(zhuang)(zhuang)置帶動(dong)筒(tong)(tong)(tong)體(ti)(ti)(ti)(ti)(ti)轉動(dong);機(ji)(ji)架用(yong)型(xing)鋼焊制。機(ji)(ji)器(qi)的所有結構均裝(zhuang)(zhuang)置于(yu)(yu)機(ji)(ji)架上，機(ji)(ji)架底部裝(zhuang)(zhuang)有4只行走(zou)輪，便(bian)于(yu)(yu)移動(dong)。整(zheng)機(ji)(ji)配用(yong)功率(lv)0.75kW，單機(ji)(ji)投葉(xie)(xie)量10~15kg。作(zuo)業時，待筒(tong)(tong)(tong)內(nei)(nei)溫度(du)達(da)到作(zuo)業要(yao)求后，將茶(cha)葉(xie)(xie)喂(wei)入滾(gun)筒(tong)(tong)(tong)內(nei)(nei)，通過(guo)控制系統調節滾(gun)筒(tong)(tong)(tong)轉速及筒(tong)(tong)(tong)內(nei)(nei)溫度(du)，至茶(cha)葉(xie)(xie)殺(sha)青適(shi)度(du)時，讓(rang)筒(tong)(tong)(tong)體(ti)(ti)(ti)(ti)(ti)出(chu)(chu)葉(xie)(xie)端向下(xia)傾斜，利用(yong)重力將茶(cha)葉(xie)(xie)排出(chu)(chu)機(ji)(ji)外。
