Embodiment
In order to more clearly understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with specific embodiment, the present invention will be further described.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt and be different from other modes described here and implement, and therefore, the present invention is not limited to the restriction of the specific embodiment of prospectus below.
Embodiment 1, the detailed step present embodiments providing corn starch milk hydrolysis process and the item that will note:
Material is the corn starch milk, α-amylase and the saccharifying enzyme that process.
First simultaneously in material-compound tank, add corn starch milk and be equivalent to add the α-amylase of corn starch milk 1/3 volume, in adding procedure, material-compound tank will progressively heat up, when being warming up to 110 DEG C, keep this temperature and maintain 1 minute (fully mixing with α-amylase to make W-Gum, when adding, the flow of corn starch milk and α-amylase should be controlled, find through lot of experiments, the flow of corn starch milk remains on 99169Kg/h, the flow of α-amylase remain on 5.0L/h can make corn starch milk and α-amylase abundant, consider that the activity of normal enzyme reduces along with the rising of temperature, and the decline of enzyme activity can bring the harm of two aspects, one is affect hydrolysis effect, the consumption increasing enzyme in production again, therefore use high temperature resistant α-amylase in the present embodiment),
Then by the liquid in material-compound tank by pump delivery to maintenance tank in and utilize air-cooler flash distillation to cool to 95 DEG C and maintain 20 minutes; Again by the Liquid transfer that maintains in tank in vapor can, then be warmed up to 135 DEG C by steam heating and maintain 15 seconds;
After above-mentioned steps terminates, by in the Liquid transfer in vapor can tank to liquefied pot and flash distillation cool to 93 DEG C, carry injection simultaneously in the process of cooling to add the α-amylase being equivalent to add at first corn starch milk 2/3 volume again and carry out enzyme, in liquefied pot, temperature maintains 93 DEG C and 90 minutes, after end, obtain liquefying starch breast.
In above process, should note second time add α-amylase charging pump and and charging pump for transmitting corn starch milk higher because of material viscosity, rotor pump or motor can be selected to join bigger impeller pump.First time the charging pump that adds α-amylase because of viscosity lower, Ordinary Centrifugal Pumps is best, can not think that rotor pump is better by mistake, during with rotor pump conveying low viscosity material, due to the leakage in gap between rotor, does not often reach its flow indicated and lift.The charging pump lift that once interpolation is sprayed and secondary interpolation is sprayed all should be not less than 50m, otherwise the fluctuation that flow can be caused large because of the change of its back pressure, even produce high vibration.Because temperature exceedes the boiling point 100 DEG C of water under normal pressure, back pressure and the temperature of material-compound tank have corresponding relation, and the change of temperature can cause the change of back pressure.High temperature after material-compound tank maintains pipe end and back pressure valve must be established to guarantee that material does not seethe with excitement in maintenance tank, installs the back pressure valve that can automatically regulate additional and can only reduce and can not eliminate the fluctuation of back pressure completely.
To obtain liquefying starch breast is transported in saccharifying tank, adds saccharifying enzyme simultaneously, and the amount of putting into of saccharifying enzyme is answered, and add by the amount of every gram of starch milk 20U, and holding temperature is at 60 DEG C, pH value is 4.5, and stirring reaction 60h, finally obtains saccharified liquid.
The manipulation of saccharifying is simple more than liquefaction, mainly should note pH value regulation and control, temperature adjusting, concentration regulation and control, enzyme-added normal and saccharification mixing control, only have these aspects all to control very well, the saccharification result that could obtain.
PH value wants to regulate and control, except regularly PH meter being verified, to just the saccharifying tank of pan feeding respectively at material level 30%, 65% and canful time sampling censorship also very important.When just finding after canful that PH is not right, particularly PH on the low side needs adds alkali readjustment again, and operation will be very loaded down with trivial details, and can bring large loss to production.
Temperature adjusting is relatively simple, on computer-controlled program, be preferably provided with saccharification pan feeding temperature deviation report to the police, and each saccharifying tank is filled with thermometer, if the thermometer on tank and corresponding pan feeding valve and liquidometer chain, also can realize arranging computer temperature deviation automatic alarm to the saccharifying tank just at pan feeding.Single tank saccharification time was generally considered by 60 hours, and in order to ensure that the temperature drop of saccharifying is less than 1 DEG C, for large-scale saccharifying tanks more than 650 cubic capacitys, consider climatic factor, the rock wool heat-preservation layer thickness giving saccharifying tank 100 ~ 150mm is necessary.
Suitably to dilute the feed thickness of saccharifying tank by adding the sugar water returned from ion-exchange in order to obtain saccharification height DX value (ratio that glucose accounts for total reducing sugar is called DX value).Feed thickness is lower, and the final DX of saccharification can be higher, but reduces burden and energy consumption that feed thickness can increase subsequent evaporation operation.Be more reasonably that saccharification feed thickness is diluted to 32 ~ 33 ° of BX from 33 ~ 35 ° of BX, such saccharification end of a period concentration at 34 ~ 35 ° of BX, both can ensure that higher DX, can not increase too many water again.
Saccharifying tank is as too slow in caused saccharification because of the enzyme-added system fault or deficient enzyme activity, can add saccharifying enzyme directly to saccharifying tank.The timing from pan feeding canful of each saccharifying tank of general requirement, when saccharification 15h, 30h, 45h and 60h, HPLC (high pressure liquid chromatography) detection is done in sampling respectively, to understand the situation of saccharification in time.
Adopt large-scale saccharifying tank in the present embodiment, therefore need be equipped with frequency transformer to the stirring of saccharifying tank, use frequency transformer adjustable go out a suitable mixing speed, stirring is rocked comparatively light, also reduces electric consumption simultaneously.Each saccharifying tank in its whole saccharification period to the demand of stirring intensity be change: in order to material in abundant mixing tank during saccharifying tank pan feeding, now stirring intensity is maximum; Reduce to increase average filtration rate the diatomite consumption that follow-up vacuum drum filters, before saccharifying tank discharging and discharging allow stirring stop for some time (dropping to 40% to discharge tank liquid level from saccharification 60h) early stage; As for saccharifying, stir and mainly avoid albumen or zymin and material layering to cause saccharification uneven, the stirring intensity of needs is less, can allow stir often to run within 10 minutes, rest 20 minutes.To every manipulation of stirring, can be realized by computer controlled automatic.
Find after testing, the DE value of the corn starch milk obtained after using present method hydrolysis is 98.2%, and the DE value of traditional method is all lower than 98%, about 97.5%, illustrates that present method is better than traditional method.
The above; it is only preferred embodiment of the present invention; it is not restriction the present invention being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field; but everyly do not depart from technical solution of the present invention content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present invention is done above embodiment, still belong to the protection domain of technical solution of the present invention.
