On other hand, the hydrolyze function of the acid protease can
increase the a-amino nitrogen level, improve the growth and
propagation of yeast, increase the fermentation speed, shorten the
fermentation period and increase efficiency of fermentation
tanks.
1. Optimum Condition
Acid protease suitable for alcohol production from corn, sorghum,
rye and other starch materials. The optimum pH 2.**6.0, and
temperature is ****5.
2. Dosage
The dosage of acid protease used is ****6 U/g raw materials; it
depends on different raw material and fermentation process. In most
cases, each gram raw material need *4U/g acid protease, **0g/ton
acid protease (****0u/g), or **0g/tone acid protease
(****0u/g).
3. Application
(1) Re-activation of acid protease: dissolve the acid protease in
****0 warm water, soak and activate for 1 hour, stir every *5
minutes.
(2) Batch fermentation: when the sacrificed slurry reaches 1/3 of
the fermentation tank, add all liquid and residues part at one
time.
(3) Cascade fermentation and semi-continuous fermentation: Depends
on the production volume, add acid protease continuously during
fermentation. For a *0 ton/day (*0,**0 ton/year) alcohol plant, the
adding rate acid protease is *0 liter/ hour.
4. Others
(1) As the optimum temperature of acid protease is ~ *0, it is
suggested to use the thermo yeast.
(2) The use of acid protease can shorten the fermentation cycle
greatly to *****5 hours. After fermentation, discharge the tank
immediately; avoid alcohol lost and increase of acidity.
(3) After the use of acid protease, the number of yeast will
doubled, fermentation speed will greatly increase, so its better to
control the fermentation temperature, the highest temperature
should not be more than *0.
