Design annual output of 1000T alkaline

protease workshop

Abstract:The alkaline protease is one of very important industrial enzymes,and

how to produce the plant effectively is particularly important.This paper introduces

the process that use liquid fermentation on the production of alkaline protease, use

two-phase extraction for purification of water, freeze-drying process to dry the

product;and through the material balance, heat balance, equipment selection, etc. I

preliminary design the annual output of several steps 1000T alkaline protease

workshop projects;I analysis of the shortcomings of traditional crafts and problems

in the pape;I have also talked about the prospects for the development of alkaline

protease, and the purpose and meaning;and ultimately design a process flow

diagram with control points, equipment layout diagram, fermentor assemble

diagram.

Key words: Alkaline protease;Liquid Aermentation;Aqueous two-phase extraction;

Areeze Drying ;Workshop
