工作原理：
本實(shi)用新型涉及一(yi)種(zhong)中藥(yao)、食品(pin)、保健品(pin)、化工生產的新裝置(zhi)。它是由一(yi)效列管加(jia)熱器(qi)、蒸發室(shi)、二效列管加(jia)熱器(qi)、濃(nong)縮(suo)鍋、冷凝冷卻器(qi)、真空溶媒回收罐、(板式換(huan)熱器(qi)、真空緩沖罐)組成。
設(she)備連接是由(you)一(yi)效外循(xun)環濃(nong)縮(suo)鍋的(de)二次蒸汽(qi)口通過氣動(dong)閥分別連接二效加熱室(shi)和冷凝(ning)冷卻(que)器，根據(ju)生(sheng)(sheng)產不(bu)同(tong)的(de)規(gui)模(mo)及要求采用不(bu)同(tong)的(de)生(sheng)(sheng)產方式(雙效或單效)。
在(zai)(zai)(zai)雙效(xiao)(xiao)(xiao)(xiao)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)時(shi)利(li)用(真空(kong)度(du)(du)0.04Mpa，藥(yao)液溫(wen)度(du)(du)80多度(du)(du))一(yi)效(xiao)(xiao)(xiao)(xiao)的(de)(de)(de)二(er)(er)次蒸(zheng)汽供應二(er)(er)效(xiao)(xiao)(xiao)(xiao)濃(nong)(nong)(nong)縮(suo)加熱(真空(kong)度(du)(du)0.08Mpa，藥(yao)液溫(wen)度(du)(du)60多度(du)(du))，可(ke)根據(ju)要(yao)求在(zai)(zai)(zai)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)大比重浸(jin)膏時(shi)：一(yi)效(xiao)(xiao)(xiao)(xiao)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)浸(jin)膏比重在(zai)(zai)(zai)1.2左右(you)時(shi)并罐于二(er)(er)效(xiao)(xiao)(xiao)(xiao)組合式(shi)濃(nong)(nong)(nong)縮(suo)繼續濃(nong)(nong)(nong)縮(suo)可(ke)達(da)到(dao)1.4左右(you)時(shi)出膏，在(zai)(zai)(zai)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)過程(cheng)中采用它充(chong)分(fen)達(da)到(dao)節能(neng)(neng)的(de)(de)(de)作(zuo)用。在(zai)(zai)(zai)單效(xiao)(xiao)(xiao)(xiao)單臺(tai)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)時(shi)利(li)用單效(xiao)(xiao)(xiao)(xiao)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)時(shi)間(jian)短、速度(du)(du)快(kuai)、操作(zuo)簡(jian)便的(de)(de)(de)優勢，在(zai)(zai)(zai)有(you)效(xiao)(xiao)(xiao)(xiao)利(li)用能(neng)(neng)源(yuan)(提(ti)取液溫(wen)度(du)(du)在(zai)(zai)(zai)90度(du)(du)左右(you)時(shi)濃(nong)(nong)(nong)縮(suo)真空(kong)度(du)(du)在(zai)(zai)(zai)-0.08Mpa時(shi)沸(fei)點(dian)溫(wen)度(du)(du)為60度(du)(du)采用單效(xiao)(xiao)(xiao)(xiao)為最佳)充(chong)分(fen)發揮(hui)單效(xiao)(xiao)(xiao)(xiao)的(de)(de)(de)優勢可(ke)緩解生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)急需(xu)。利(li)用冷凝(ning)冷卻器(qi)的(de)(de)(de)面積大可(ke)以進(jin)行單效(xiao)(xiao)(xiao)(xiao)或組合式(shi)濃(nong)(nong)(nong)縮(suo)的(de)(de)(de)單臺(tai)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)，在(zai)(zai)(zai)兩臺(tai)分(fen)別同時(shi)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)是單效(xiao)(xiao)(xiao)(xiao)的(de)(de)(de)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)，如若(ruo)回收溶媒可(ke)通過真空(kong)保護系統(tong)中的(de)(de)(de)板式(shi)緩沖罐進(jin)行操作(zuo)。
