本文的設(shè)計(jì)項(xiàng)目為“年產(chǎn)20000t味精工廠發(fā)酵車(chē)間設(shè)計(jì)”。設(shè)計(jì)內(nèi)容是：根據(jù)實(shí)際情況給發(fā)酵車(chē)間選擇合適的生產(chǎn)工藝流程，對(duì)生產(chǎn)流程中的原料進(jìn)行物料衡算、熱量衡算，并對(duì)生產(chǎn)中主要的專業(yè)設(shè)備進(jìn)行了設(shè)計(jì)、相關(guān)配套設(shè)備進(jìn)行了選型。

設(shè)計(jì)內(nèi)容具體可分為三個(gè)方面。味精發(fā)酵車(chē)間生產(chǎn)工藝的選擇；發(fā)酵車(chē)間工藝計(jì)算（物料衡算、熱量衡算、無(wú)菌空氣衡算等）；發(fā)酵車(chē)間發(fā)酵罐、種子罐、空氣過(guò)濾器、連消塔等設(shè)備的設(shè)計(jì)以及空壓機(jī)、泵等輔助設(shè)備的選擇。

通過(guò)本設(shè)計(jì)的實(shí)施，可以使我國(guó)的味精生產(chǎn)技術(shù)趕上國(guó)際領(lǐng)先水平，可以擴(kuò)大國(guó)內(nèi)市場(chǎng)占有率，提高我國(guó)味精行業(yè)的整體水平，增加其在國(guó)際市場(chǎng)上的競(jìng)爭(zhēng)力，還可以給中國(guó)的農(nóng)副產(chǎn)品找到一條深加工的出路。

Abstract

In this paper, the designing is: Designing of the Fermentation Workshop in Monosodium Glutamate Factory with Annual Production of 20000t.The designing contains: Choose a suitable production process for the Fermentation Workshop according to the actual situation, Calculate the Material balance & Heat balance of the raw materials in this process while the mainly professional equipments in this process have been designed, related equipments have been selected.

The contents of the designing can be specifically divided into three areas. the selection of production process for the fermentation workshop; Process Calculation (Material balance,heat balance,sterile air balance) of the fermentation workshop; the designing of fermentation tank, seeding tank, air filter, culture medium sterilizing column & the selection of air compressor, pump and the other auxiliary equipment for the fermentation workshop.

Through the implementation of this designing, can make our monosodium glutamate fermentation technology catch up with the international level, can expand the domestic market share, can improve the production level of monosodium glutamate industry in order to increase the competitiveness in the international market,and so it can provide a way for China’s agricultural products.

Key Words: Monosidum glutanate; Fermentation; Frmentation process; Fermentation Tank
