The process of sterilization and bacteria inhibition of the method includes: the sterilization process of reaction liquid, the sterilization and bacteria inhibition process of thick yam liquid and the sterilization and bacteria inhibition process of hydrolyzation and fermentation. The method realizes the state of high efficiency of sterilization and bacteria inhibition; and especially in the process of hydrolyzation and fermentation, the rate of mixed bacteria is controlled to be under 0.01 percent, the implementation of the process of normal temperature hydrolyzation and fermentation is ensured, and the low-viscosity clear production technology can be finally realized.
Description
Technical field:
A kind of method for multiply sterilizing and inhibiting bacteria of yams by ethanol, the produced amylolysis ferment that is used for potato class material is handled, and belonging to the potato raw starch is the alcoholic acid hydrolysed ferment field of engineering technology of raw material production.
Background technology:
It is to carry out the fermenting and producing swort again after the steaming and decocting, gelatinizing, liquefaction, saccharifying by comprising high temperature and middle temperature that existing potato class is produced alcoholic acid technology, liquid-solid again separation after directly swort slightly being heated up in a steamer again, its wine liquid rectification again becomes ethanol, its technological process is as follows: earlier potato raw material is processed into the powder slurry, then it is carried out steaming and decocting, make its gelatinizing and liquefaction, adding saccharifying enzyme then makes it become fermentable sugar, add therein then by yeast and ferment, slightly steam again and smart the steaming through the mature seed that obtains that spreads cultivation.There is following problem and shortage in technology at present: 1, digestion process power consumption water consumption; 2, liquefaction, saccharifying separate with sweat to be carried out; 3, separate again after directly slightly heating up in a steamer after the fermentation, form waste residue environmental protection treatment difficulty; 4, the waste liquid that slightly heats up in a steamer after the rectification is difficult to reclaim; 5, whole process flow is longer, and is not easy miniaturization.
Summary of the invention:
The objective of the invention is problem, utilize a kind of non-evaporating ordinary-temp hydrolysis fermentation technology that boils of the thermodynamics basic skills invention of the enzyme kinetics ultimate principle of starch slurry biological respinse and ordinary-temp hydrolysis fermentation dynamic equilibrium at the deficiencies in the prior art and existence.Because the non-evaporating varied bacteria growing that boils in the process posthydrolysis fermentation needs to solve, the present invention guarantees that with this multiply sterilizing bacteriostasis method assorted bacterium rate in the hydrolysed ferment process is below 0.01%.
The present invention is achieved in that potato class multiply sterilizing bacteriostasis method of the present invention comprises following processing procedure composition:
1. the sterilization processing of reactant liquor;
2. the bactericidal of potato slurry is handled;
3. the bactericidal of hydrolysed ferment process is handled;
The present invention includes following processing step:
The first step to the reactant liquor that enters the spice process through pyroprocess and use nanometer silver to solidify network method it is sterilized;
Second step used ozone sterilization and suppressed assorted bacterium with extraordinary biological bacteriostatic agent the potato slurry that enters the hydrolysed ferment process;
The tank body of the 3rd step to hydrolysed ferment carries out high-temperature water and the sterilization of high temperature vapour, and suppresses assorted bacterium with extraordinary biological bacteriostatic agent;
It is a kind of disinfection system efficiently that the nanometer silver that is adopted among the present invention solidifies webmaster, and assorted bacterium such as escherichia coli, mycete are had killing action efficiently; A kind of ozone efficiently of ozone sterilization system formula among the present invention takes place and conveying equipment; Biological bacteriostatic agent among the present invention is a kind of assorted bacterium to be had inhibitory action, yeast is had the biological preparation of facilitation.
Characteristics of the present invention and beneficial effect are: in whole hydrolysed ferment process, assorted bacterium rate is below 0.01%, the hydrolysed ferment process is carried out under aseptic condition, and the assorted bacterium that the non-evaporating process of boiling that overcomes causes generates problem, has realized the ordinary-temp hydrolysis fermentation and the process for cleanly preparing of formation.
Specific implementation method: the present invention includes following technology content:
The sterilization processing of first step reactant liquor
The reactant liquor that enters the spice process is through thick gold-plating kettle base solution and rectification distilled water behind the high temperature, and reactant liquor solidifies webmaster by nanometer silver and sterilizes once more before entering the spice jar.
The bactericidal of the second step potato slurry is handled
The potato slurry that enters in the hydrolysed ferment process carries out ozone sterilization and adds extraordinary biological bacteriostatic agent, suppresses varied bacteria growing.
The bactericidal of the 3rd one-step hydrolysis sweat is handled
Before potato slurry enters the fermentation tank body, with the high-temperature water of rectification it is washed, and sterilize with steam, after entering fermentation tank, the potato slurry suppresses varied bacteria growing with extraordinary biological bacteriostatic agent, and the hydrolysis and the zymic Fermentation of promotion enzyme.
Generate alcoholic acid examples of implementation with Radix Ipomoeae:
The sterilization processing of first step reactant liquor
1. reactant liquor is partly formed by two, and some is through the pyritous kettle base solution of thick gold-plating, and some is to pass through the distilled water of rectification, both reaction flow containers of packing into.
2. the reactant liquor that will react flow container sterilizes by the nanometer silver cure system in entering the spice process.
The bactericidal of the second step potato slurry is handled
1. potato starch and reactant liquor are become the potato slurry by 1: 3 solid-to-liquid ratio spice, and the ozone that produces by ozonator sterilizes in the spice process.
2. with importing filtrated air after the ozone sterilization process, remove residual ozone, and add extraordinary biological bacteriostatic agent.
The bactericidal of the 3rd one-step hydrolysis sweat is handled
1. the tank body that carries out of 100 ℃ of thick gold-plating kettle base solutions of utilization washes before the potato slurry enters.
2. before entering, the potato slurry sterilizes with the surplus steam of the rectification more than 120 ℃.
3. in the hydrolysed ferment process, add extraordinary biological bacteriostatic agent.
