全自動(dòng)生物發(fā)酵罐
發(fā)酵罐概述Overview Of Fermentation Tank
常見的發(fā)酵罐分為固體發(fā)酵罐和液體發(fā)酵罐。發(fā)酵罐根據(jù)容積和用途不同,分為種子罐(菌種發(fā)酵罐)和發(fā)酵罐。發(fā)酵罐根據(jù)需氧類型的不同又分為通風(fēng)式發(fā)酵罐和厭氧發(fā)酵罐。發(fā)酵罐、種子罐,有碳鋼制、不銹鋼、高鎳基合金等,主要用于生化發(fā)酵生產(chǎn)。如生產(chǎn)味精、檸檬酸、酶制劑、溶劑、制藥、食品等行業(yè)。
一、發(fā)酵罐的基本條件Basic Conditions Of Fermentation Tank
機(jī)械攪拌發(fā)酵罐是發(fā)酵工廠常用類型之一。它是利用機(jī)械攪拌器的作用,使空氣和醪液充分混合,促使氧在醪液中溶解,以保證供給微生物生長(zhǎng)繁殖、發(fā)酵所需要的氧氣。使用發(fā)酵罐的基本要求:
1、發(fā)酵罐應(yīng)具有適宜的徑高比。發(fā)酵罐的高度與直徑之比一般為1.7~4倍左右,罐身越長(zhǎng),氧的利用率較高。
2、發(fā)酵罐能承受一定壓力。由于發(fā)酵罐在消毒及正常工作時(shí),罐內(nèi)有一定的壓力(氣壓與液壓)和溫度,因此罐體各部件要有一定的強(qiáng)度,能承受一定的壓力。
3、發(fā)酵罐的攪拌通風(fēng)裝置使氣液充分混合,保證發(fā)酵液必須的溶解氧。
4、發(fā)酵罐應(yīng)具有足夠的冷卻面積。微生物生長(zhǎng)代謝過(guò)程放出大量的熱量,為了控制發(fā)酵過(guò)程不同階段所需的溫度,應(yīng)裝有足夠的冷卻面積。
5、發(fā)酵罐內(nèi)應(yīng)盡量減少死角,避免藏垢積污,易滅菌,避免染菌。
6、攪拌器的軸封應(yīng)嚴(yán)密,盡量減少泄漏。
二、發(fā)酵罐罐體尺寸比例Size Proportion Of Fermentation Tank
罐體各部分的尺寸有一定的比例,罐的高度與直徑之比一般為1.7~4倍左右。
發(fā)酵罐通常裝有兩組攪拌器,兩組攪拌器的間距S約為攪拌器直徑的三倍。
對(duì)于大型發(fā)酵罐以及液體深度HL較高的,可安裝三組或三組以上的攪拌器。
最下面一組攪拌器通常與風(fēng)管出口較接近為好,與罐底的距離C一般等于攪拌器直徑Di,但也不宜小于0.8Di,否則會(huì)影響液體的循環(huán)。
三、發(fā)酵罐的結(jié)構(gòu)Structure Of Fermentation Tank
好氣性機(jī)械攪拌發(fā)酵罐是密封式受壓設(shè)備,主要部件包括罐身、攪拌器、軸封、打泡器、聯(lián)軸器、中間軸承、空氣吹泡管(或空氣噴射器)、擋板、冷卻裝置、人孔以及管路等。
系統(tǒng)由發(fā)酵罐,空氣處理系統(tǒng)、蒸汽凈化系統(tǒng)、電器控制系統(tǒng)、恒溫系統(tǒng)及管路、閥門、輔助系統(tǒng),傳感器與一次儀表系統(tǒng),下位機(jī)控制系統(tǒng)(現(xiàn)場(chǎng)PLC控制系統(tǒng),二次儀表),上位機(jī)系統(tǒng)以及臺(tái)架等組成。
