Plant Design of Sixty thousand t/a
α
-Amylase
Abstract:
This project is designed by a factory which produces 60,000t
α
-Amylase a year.It achieves the aim
of filt
ration 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
500m
3
,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.
