工作原理：

本實用新型涉及一種中藥、食(shi)品、保健品、化工生產的新裝置。它是由一效(xiao)列管加熱器(qi)(qi)、蒸(zheng)發室、二效(xiao)列管加熱器(qi)(qi)、濃縮鍋(guo)、冷凝(ning)冷卻器(qi)(qi)、真(zhen)空(kong)(kong)溶媒回收罐(guan)、(板式(shi)換熱器(qi)(qi)、真(zhen)空(kong)(kong)緩(huan)沖罐(guan))組成。

設備連(lian)接是由一效(xiao)外循(xun)環濃縮(suo)鍋的(de)二(er)次蒸汽(qi)口通過氣動閥(fa)分別連(lian)接二(er)效(xiao)加熱室和(he)冷凝冷卻器，根(gen)據(ju)生(sheng)產不同的(de)規模及要(yao)求采用不同的(de)生(sheng)產方式(雙效(xiao)或單效(xiao))。

在雙(shuang)效(xiao)(xiao)(xiao)(xiao)生(sheng)產(chan)(chan)時(shi)(shi)(shi)利(li)用(yong)(yong)(真空度(du)(du)0.04Mpa，藥液(ye)溫度(du)(du)80多(duo)度(du)(du))一效(xiao)(xiao)(xiao)(xiao)的(de)二(er)(er)次蒸(zheng)汽供(gong)應二(er)(er)效(xiao)(xiao)(xiao)(xiao)濃縮(suo)加熱(真空度(du)(du)0.08Mpa，藥液(ye)溫度(du)(du)60多(duo)度(du)(du))，可(ke)根(gen)據(ju)要求在生(sheng)產(chan)(chan)大比重浸(jin)膏時(shi)(shi)(shi)：一效(xiao)(xiao)(xiao)(xiao)生(sheng)產(chan)(chan)浸(jin)膏比重在1.2左右(you)(you)(you)時(shi)(shi)(shi)并罐于(yu)二(er)(er)效(xiao)(xiao)(xiao)(xiao)組(zu)合(he)式(shi)濃縮(suo)繼(ji)續濃縮(suo)可(ke)達到1.4左右(you)(you)(you)時(shi)(shi)(shi)出(chu)膏，在生(sheng)產(chan)(chan)過(guo)程中采用(yong)(yong)它(ta)充分達到節能的(de)作用(yong)(yong)。在單(dan)效(xiao)(xiao)(xiao)(xiao)單(dan)臺(tai)生(sheng)產(chan)(chan)時(shi)(shi)(shi)利(li)用(yong)(yong)單(dan)效(xiao)(xiao)(xiao)(xiao)生(sheng)產(chan)(chan)時(shi)(shi)(shi)間短、速度(du)(du)快、操(cao)(cao)作簡便的(de)優勢，在有(you)效(xiao)(xiao)(xiao)(xiao)利(li)用(yong)(yong)能源(提取液(ye)溫度(du)(du)在90度(du)(du)左右(you)(you)(you)時(shi)(shi)(shi)濃縮(suo)真空度(du)(du)在-0.08Mpa時(shi)(shi)(shi)沸(fei)點溫度(du)(du)為60度(du)(du)采用(yong)(yong)單(dan)效(xiao)(xiao)(xiao)(xiao)為最佳)充分發揮(hui)單(dan)效(xiao)(xiao)(xiao)(xiao)的(de)優勢可(ke)緩解(jie)生(sheng)產(chan)(chan)急需。利(li)用(yong)(yong)冷(leng)凝(ning)冷(leng)卻(que)器的(de)面(mian)積大可(ke)以進行單(dan)效(xiao)(xiao)(xiao)(xiao)或組(zu)合(he)式(shi)濃縮(suo)的(de)單(dan)臺(tai)生(sheng)產(chan)(chan)，在兩臺(tai)分別同(tong)時(shi)(shi)(shi)生(sheng)產(chan)(chan)是單(dan)效(xiao)(xiao)(xiao)(xiao)的(de)生(sheng)產(chan)(chan)，如若回收溶(rong)媒可(ke)通過(guo)真空保護系統(tong)中的(de)板式(shi)緩沖(chong)罐進行操(cao)(cao)作。
