Abstract
The invention discloses a kind of method for controlling rice liquefaction DE values.The size controlling that method is crushed by 1) rice, 2) configuration of rice slurry, the 3) preparation of liquefied fermented glutinous rice, the 4) preparation of ripe mash.The beneficial effects of the invention are as follows：1. the preparation method progress Rice Powder of the application present invention is slurried, solve the problems, such as that rice liquefied fermented glutinous rice is sticky.2. by the accurate control for the DE values that liquefy, slurry appearance sugar is improved, residual starch is not only reduced, improves 12.5 13%.
Description
Technical field
The invention belongs to technical field prepared by ethanol, is specifically a kind of method for controlling rice liquefaction DE values.
Background technology
With China's grain " 11 even increase ", policy grain stores up policy and is protecting peasant to plant the same of grain enthusiasm
When, also bring new quagmire：Staggering amount library tape carrys out staggering amount cost, and finance can't bear the heavy load, and digest grain in storage for years be also required to it is new
Outlet." alcohol fuel is the realistic approach that scale solves the problems, such as ' grain '." Guangxi COFCO Bio-energy Co., Ltd.'s root
According to existing fuel ethanol production process condition, the condition for being aged rice producing fuel ethyl alcohol by ferment is studied, using now
There is device to realize ageing rice and produce alcohol fuel in a manner of full rice, faster to consume more rice, have found
New approach.The present invention develops a kind of method for controlling rice liquefaction DE values.
The content of the invention
The object of the present invention is to provide a kind of method for controlling rice liquefaction DE values.
The technical solution that the present invention solves above-mentioned technical problem is as follows：
The method of one rice liquefaction DE value control technologies, operates according to following steps：
1. the full rice with shell, after crushing, for grinding particle size by 20 mesh sieves, percent of pass >=90%, ensures the equal of material
Even property, obtains the full Rice Powder with shell.
2. full Rice Powder of the step 1 with shell be put into slurry processed in slurry tank, the dry substance concentration in slurry accounts for slurry weight
The 27~29% of amount, at 84~86 DEG C, slurry pH is controlled 5.4~5.6 slurry temperature control.
3. amylase is added into the slurry of step 2, additive amount 0.13kg/tRaw material, injection liquefaction is carried out using steam,
Injector temperature control in 95~97 DEG C, condensing temperature control at 93~98 DEG C, time 2h.Then through first time flash temperature
86 DEG C are down to, second of flash temperature is down to 70 DEG C, finally carries out being cooled to 28~32 DEG C using recirculated cooling water, is liquefied
Wine with dregs, at this time liquefied fermented glutinous rice DE values 9~13%.
4. the liquefied fermented glutinous rice of step 3 is transported to fermentation tank, and it is 4.4~4.6 to add the concentrated sulfuric acid to adjust pH, addition saccharification
Enzyme, additive amount are 1~1.2kg/tRaw material；25~30% yeast wash of fermentation liquid quality is added at the same time, and yeast wash is in production
Culture, it contains yeast number 2.5~300,000,000/ml, and the death rate is below 3%.Middle stirring at low speed makes under the conditions of being 28~30 DEG C in temperature
It ferments, and temperature obtains ripe mash in 33~34 DEG C of continuing fermentation 60h, and ripe raw spirit point brings up to 12.5~13%.
The beneficial effects of the invention are as follows：
1. application the present invention controlling technical method, solve the problems, such as full starch can not normal fermentation solve liquefied fermented glutinous rice
After the problem of liquid is sticky, slurry appearance sugar is improved, fermented wine part is brought up to 12.5~13% by 11%~12% (V).
2. by adjusting pre liquefied temperature, 84~86 DEG C are adjusted to by original 82~83 DEG C, the liquefied fermented glutinous rice after adjustment
Liquid liquefaction effect is good, and iodine examination is in aubergine.
Both the above effect prepares alcohol technology in rice fermentation and belongs to pioneering, solves asking for rice liquefaction DE value controls
Topic.
