目前，市場上流行的殺青機械多是以微波殺青機(ji)、滾筒(tong)殺青機(ji)和燃(ran)氣炒青機(ji)為主。
1.微波殺(sha)青(qing)機
微波殺(sha)青(qing)設(she)備是(shi)一種新型的(de)(de)(de)(de)殺(sha)青(qing)設(she)備，殺(sha)青(qing)速度快、效(xiao)率(lv)高、效(xiao)果好。在殺(sha)青(qing)的(de)(de)(de)(de)同(tong)時，還可以除去(qu)約10%的(de)(de)(de)(de)鮮(xian)葉水(shui)分(fen)。的(de)(de)(de)(de)原(yuan)理主要是(shi)利(li)用迅(xun)速升溫來鈍(dun)化鮮(xian)葉的(de)(de)(de)(de)的(de)(de)(de)(de)活性氧(yang)化酶，抑(yi)制鮮(xian)葉中(zhong)的(de)(de)(de)(de)茶多(duo)酚等酶加速氧(yang)化，防(fang)止在后(hou)續烘干過(guo)程中(zhong)發生色澤嚴重改變，同(tong)時揮發鮮(xian)葉的(de)(de)(de)(de)腥草味，使茶香更(geng)好的(de)(de)(de)(de)形成(cheng)。
采(cai)用微波殺青(qing)設備對茶葉、菊(ju)花、金(jin)銀花等農產品進(jin)行殺青(qing)，平均每公(gong)斤的(de)量所需要的(de)電費不到三毛錢，而且殺青(qing)效果顯著，產品色澤、外形和(he)香氣(qi)都屬上佳品。
2.滾筒(tong)殺青機
烏龍(long)茶殺青常(chang)用90型(xing)與110型(xing)兩(liang)種(zhong)機型(xing)，該機結構緊湊、操作方便(bian)、效率高。爐火(huo)直接加熱轉動的筒
體，茶葉(xie)在(zai)筒(tong)(tong)(tong)(tong)(tong)(tong)體內靠摩擦和(he)筒(tong)(tong)(tong)(tong)(tong)(tong)體轉(zhuan)(zhuan)(zhuan)動的(de)(de)離心力在(zai)滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)內拋(pao)轉(zhuan)(zhuan)(zhuan)，并(bing)吸(xi)收熱量(liang)達到殺青(qing)目的(de)(de)。殺青(qing)適度后(hou)，反(fan)轉(zhuan)(zhuan)(zhuan)滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)，利用(yong)(yong)筒(tong)(tong)(tong)(tong)(tong)(tong)壁的(de)(de)螺旋導葉(xie)板(ban)將(jiang)茶葉(xie)推(tui)出筒(tong)(tong)(tong)(tong)(tong)(tong)外(wai)。同時，借(jie)助滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)末(mo)端(duan)的(de)(de)風(feng)扇(shan)將(jiang)筒(tong)(tong)(tong)(tong)(tong)(tong)內茶葉(xie)排凈。該(gai)機(ji)由滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)、傳(chuan)動裝(zhuang)置(zhi)(zhi)、風(feng)扇(shan)、機(ji)架、爐(lu)灶(zao)等部(bu)分組成。滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)用(yong)(yong)鋼板(ban)卷制而成，內壁焊有導葉(xie)板(ban)，導葉(xie)角為24°，其(qi)作用(yong)(yong)是幫助進葉(xie)或推(tui)出殺青(qing)葉(xie)，并(bing)將(jiang)茶葉(xie)帶至一(yi)定高度后(hou)拋(pao)下。風(feng)扇(shan)可正(zheng)、反(fan)轉(zhuan)(zhuan)(zhuan)，以吹(chui)葉(xie)出筒(tong)(tong)(tong)(tong)(tong)(tong)或吸(xi)排濕氣。滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)兩端(duan)外(wai)圍設有擋煙(yan)(yan)圈，中心有一(yi)轉(zhuan)(zhuan)(zhuan)軸，通過兩端(duan)的(de)(de)輻條與筒(tong)(tong)(tong)(tong)(tong)(tong)體相接，轉(zhuan)(zhuan)(zhuan)軸由軸承支撐于(yu)機(ji)架上。機(ji)架一(yi)般用(yong)(yong)角鋼制作。爐(lu)灶(zao)由通風(feng)道、爐(lu)柵、爐(lu)膛、煙(yan)(yan)囪(cong)等組成。滾(gun)筒(tong)(tong)(tong)(tong)(tong)(tong)體置(zhi)(zhi)于(yu)爐(lu)膛內，爐(lu)膛頂部(bu)有拔風(feng)口(kou)與煙(yan)(yan)囪(cong)相通。110型殺青(qing)機(ji)傳(chuan)動配用(yong)(yong)功(gong)率(lv)1.1kW，投葉(xie)量(liang)15~25kg,風(feng)機(ji)功(gong)率(lv)0.75kW。
3.燃(ran)氣炒青(qing)機
該(gai)機(ji)以液化氣(qi)為(wei)熱源，作(zuo)(zuo)(zuo)業穩定，殺(sha)青均(jun)勻，清潔衛生、操作(zuo)(zuo)(zuo)方便。該(gai)機(ji)為(wei)滾(gun)筒(tong)式(shi)，由滾(gun)筒(tong)、火排(pai)加熱系(xi)(xi)(xi)統(tong)、傳動(dong)機(ji)構(gou)、出(chu)茶(cha)裝置(zhi)(zhi)、控制系(xi)(xi)(xi)統(tong)和機(ji)架(jia)組成(圖(tu)4)。滾(gun)筒(tong)體中部(bu)(bu)(bu)為(wei)圓(yuan)筒(tong)式(shi)結(jie)構(gou)，兩端為(wei)150mm錐體，外筒(tong)體采用(yong)保溫材(cai)料，轉筒(tong)體下部(bu)(bu)(bu)敞開，用(yong)于(yu)安(an)裝加熱火排(pai);加熱系(xi)(xi)(xi)統(tong)使用(yong)液化氣(qi)作(zuo)(zuo)(zuo)燃(ran)料，燃(ran)燒器(qi)為(wei)直線排(pai)火式(shi)，采用(yong)電(dian)(dian)子點火裝置(zhi)(zhi);傳動(dong)機(ji)構(gou)由無級變速電(dian)(dian)機(ji)通過減速裝置(zhi)(zhi)帶(dai)動(dong)筒(tong)體轉動(dong);機(ji)架(jia)用(yong)型鋼焊制。機(ji)器(qi)的所有結(jie)構(gou)均(jun)裝置(zhi)(zhi)于(yu)機(ji)架(jia)上，機(ji)架(jia)底部(bu)(bu)(bu)裝有4只行走輪，便于(yu)移動(dong)。整(zheng)機(ji)配用(yong)功率(lv)0.75kW，單(dan)機(ji)投葉量10~15kg。作(zuo)(zuo)(zuo)業時(shi)，待筒(tong)內(nei)溫度達(da)到作(zuo)(zuo)(zuo)業要求后，將茶(cha)葉喂入滾(gun)筒(tong)內(nei)，通過控制系(xi)(xi)(xi)統(tong)調節滾(gun)筒(tong)轉速及筒(tong)內(nei)溫度，至茶(cha)葉殺(sha)青適度時(shi)，讓筒(tong)體出(chu)葉端向下傾(qing)斜，利用(yong)重力將茶(cha)葉排(pai)出(chu)機(ji)外。
