速溶茶粉凍干機:凍干(gan)茶(cha)粉(fen)是因(yin)為保(bao)持茶(cha)葉原(yuan)有的(de)色(se)澤以(yi)及(ji)營(ying)養(yang)、藥理成分基本不變,不需要添加任何化(hua)學添加劑,除了直接飲用外,可廣泛添加于于蛋糕、冰淇淋、面包、奶凍、掛(gua)面、餅干(gan)、酸奶、巧克力、豆腐等食(shi)(shi)品(pin)(pin)中;在(zai)食(shi)(shi)品(pin)(pin)、醫(yi)藥保(bao)健(jian)品(pin)(pin)、日用化(hua)工品(pin)(pin)等廣泛應用,有強化(hua)其營(ying)養(yang)保(bao)健(jian)功能(neng),方便存儲和運輸。
凍(dong)(dong)(dong)干(gan)茶粉冷凍(dong)(dong)(dong)干(gan)燥(zao)機(ji)工作(zuo)原理是(shi)根(gen)(gen)據(ju)水(shui)(shui)、冰(bing)、氣(qi)三態根(gen)(gen)據(ju)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)和(he)真(zhen)空影(ying)響下相(xiang)互轉換的(de)(de)原理。通過萃取濃縮后(hou)的(de)(de)液態茶,在(zai)低溫(wen)(wen)(wen)(wen)(wen)(wen)-45℃下預凍(dong)(dong)(dong)3~5小時(shi)(shi)結(jie)(jie)晶(jing)成固體,此時(shi)(shi)物料中心溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)錄得(de)是(shi)-45℃左(zuo)右,誤差不(bu)超過±1℃,然后(hou)進入(ru)(ru)預抽(chou)真(zhen)空,達到(dao)FZG凍(dong)(dong)(dong)干(gan)機(ji)設(she)定值和(he)運(yun)行(xing)時(shi)(shi)間(jian)后(hou),進入(ru)(ru)一(yi)次干(gan)燥(zao)階(jie)段,運(yun)行(xing)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)范(fan)圍-45~X℃,在(zai)FZG凍(dong)(dong)(dong)干(gan)機(ji)設(she)定好的(de)(de)升溫(wen)(wen)(wen)(wen)(wen)(wen)速率和(he)時(shi)(shi)間(jian)運(yun)行(xing),這一(yi)階(jie)段除去90%左(zuo)右流離水(shui)(shui)。再自動進行(xing)解(jie)析干(gan)燥(zao)階(jie)段,此時(shi)(shi)剩下是(shi)結(jie)(jie)合水(shui)(shui),因為(wei)結(jie)(jie)合水(shui)(shui)有較強分(fen)子(zi)力(li),需要(yao)更多的(de)(de)能量,所以(yi)提供更高的(de)(de)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du),物料溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)控制在(zai)共熔點溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)以(yi)內(nei)運(yun)行(xing)3~5小時(shi)(shi)后(hou),恒溫(wen)(wen)(wen)(wen)(wen)(wen)1~2小時(shi)(shi)確定真(zhen)空值運(yun)行(xing)情況。*后(hou)干(gan)燥(zao)結(jie)(jie)束得(de)到(dao)含水(shui)(shui)率5%以(yi)內(nei)的(de)(de)凍(dong)(dong)(dong)干(gan)茶粉。干(gan)燥(zao)得(de)到(dao)色、香(xiang)、味和(he)營養(yang)成分(fen)基本不(bu)變。
速溶茶粉凍干機由(you)凍干倉體、制冷系(xi)(xi)統(tong)、加熱系(xi)(xi)統(tong)、循環系(xi)(xi)統(tong)、真空系(xi)(xi)統(tong)、PLC電控系(xi)(xi)統(tong)組成。是FZG凍干機工(gong)廠(chang)設(she)計制造,配(pei)合凍干工(gong)藝技術自動運行。
