石斛凍(dong)干(gan)粉加(jia)工工藝(yi)是從新(xin)鮮原料(liao)到凍(dong)干(gan)粉整個(ge)加(jia)工工藝(yi)流程,具體如下:
1)篩(shai)選新鮮上等(deng)的石斛原料;
2)進行去雜清洗和(he)整理;
3)對(dui)石斛條(tiao)進行2cm左右(you)分段(duan);
3)把石斛段進行破壁、粉碎、打漿;
4)將(jiang)石斛(hu)漿液(ye)(ye)進行過濾,留下清液(ye)(ye);
5)通過分子篩(shai)進行常溫濃縮;
6)將石斛濃縮液裝盤(pan):1cm厚度左右;
7)真空冷(leng)凍干(gan)燥(SFD凍干(gan)工藝技術要求);
8)低溫粉(fen)碎、過篩;
9)得到石(shi)斛凍干(gan)粉進行檢測、稱重分裝(zhuang);
根據石(shi)斛(hu)凍干(gan)粉(fen)凍干(gan)工藝流程(cheng)和(he)凍干(gan)工藝技術(shu)要(yao)求,選用中(zhong)藥材凍干(gan)機進行加(jia)工生產,具有設備技術(shu)和(he)功能(neng)要(yao)求如下:
1)隔(ge)板控溫范(fan)圍:-50~80℃;
2)極限(xian)冷(leng)凝溫(wen)度:-70~-75℃;
3)極限真空度:2.6PA;
4)常溫~-40℃降溫時(shi)間:≤60min
5)箱體(ti)、隔板、冷凝器材(cai)質:304不銹鋼;
6)具(ju)有(you)凍干工藝數據(ju)設定和(he)修改功能(neng),凍干數據(ju)記錄(lu)和(he)存儲(chu)功能(neng),凍干曲線查(cha)詢和(he)密碼權限管理功能(neng);
7)具有(you)升溫速率和真空(kong)微調(diao)控(kong)制功(gong)能、各項凍干保護功(gong)能;
8)具有遠程(cheng)操作和監控功能,一鍵化(hua)霜(shuang)功能。
選用(yong)中藥(yao)材凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)機需要(yao)滿足(zu)石斛(hu)凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)粉(fen)的凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)工(gong)藝(yi)要(yao)求(qiu),廣泛應用(yong)在(zai)石斛(hu)種植基地和石斛(hu)加工(gong)企業進行凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)開發和生產,同時適用(yong)于各種藥(yao)材凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan),比如黃(huang)精凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)、天麻凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)、靈芝凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)、人參(can)凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)、熟(shu)地凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)、蟲草凍(dong)(dong)(dong)(dong)(dong)干(gan)(gan)(gan)等加工(gong)生產。
