8萬(wàn)t/a α-淀粉酶生產(chǎn)車間的設(shè)計(jì)


摘  要:本設(shè)計(jì)為年產(chǎn)80,000t α-淀粉酶的工廠設(shè)計(jì),其通過(guò)枯草桿菌液體深層發(fā)酵、沉淀法提取達(dá)到分離純化出菌體中α-淀粉酶的目的。本設(shè)計(jì)分別對(duì)α-淀粉酶的性質(zhì)、用途、工藝流程及生產(chǎn)原理都做了相關(guān)的闡述,并對(duì)有關(guān)的物料和熱量也作了相應(yīng)的衡算,以及對(duì)標(biāo)準(zhǔn)設(shè)備的選型和計(jì)算,還對(duì)工藝指標(biāo)、安全問(wèn)題和環(huán)境保護(hù)都做了詳細(xì)的闡述。通過(guò)設(shè)計(jì)得出結(jié)論:年產(chǎn)8萬(wàn)噸α-淀粉酶發(fā)酵工廠,共有18個(gè)500m3發(fā)酵罐,每月均放罐180罐,發(fā)酵周期為72小時(shí),總提取率為82%,理論α-淀粉酶產(chǎn)量為27.8噸/罐,實(shí)際α-淀粉酶產(chǎn)量為31.03噸/罐。每月應(yīng)投入生產(chǎn)總成本為3993萬(wàn)元,根據(jù)目前市場(chǎng)價(jià)格,年利潤(rùn)為6195.1萬(wàn)元。

Plant Design of Sixty thousand t/a α-Amylase
Biology Engineering  Zhang Chao  Instructor:Zhang Dawei
Abstract:This project is designed by a factory which produces 60,000t α-Amylase a year.It achieves the aim of filtration and purification of the α-Amylase by using the deep ferment of hay bacillus and settling method.The design not only respectively illustrate the quality,use,technological process and production principle but also make a materials and heat balance,the type selection and calculation of the standard equipment,further more,illustrate the technic index,the problem of security and the environmental protection detailedly.conclusion made through the design:fermentation factory of 60,000t α-Amylase a year,it contains 35 fermentor of 500m3,The monthly discharge of liquid enzyme is 175 fermentors,The fermentation time is 120 hours,The recovery of liquid enzyme is 80%,The theoretic output is 27.8t per fermentor, while the virtual output is 31.03t per fermentor.It should monthly take the total product cost as 39.93 million yuan,the annual return is 61.951 million yuan, according to the current market price.
