The invention discloses a method for producing corn starch syrup. The method comprises the following process steps: size mixing, saccharification, neutralization, first decolorization and filtration, desalination and purification, preliminary concentration, second decolorization and filtration, second concentration and sugar solution concentration. The method uses corn starch to manufacture sugar, is low in cost, has the sugar yield of about 60 percent, can additionally provide feed and other byproducts, and has high value in the popularization of using corn starch to manufacture sugar.
Description
Technical field
The present invention relates to the manufacture field of agricultural-food, especially use the syrupy method of Starch Production.
Background technology
The consumption of China's sugar is very low from productive rate, mainly is to grow cane and beet sugar manufacture in the production, because sugarcane and beet resource-constrained, it is higher to utilize them to produce the syrup cost, so nearly 76% sugared consumption relies on external import.This situation for a change when increasing sugarcane and beet sugar, is one of major measure of the sugared consumption of increase with a part of Maize Production starchy carbohydrate.
Corn starch syrup be starch when acid or enzymic hydrolysis, control certain hydrolysis degree and the product that makes, its sugar consists of mixtures such as glucose, oligose and dextrin.Adopt different acid system or enzymatic hydrolysis, can control the ratio of this sugar arbitrarily, so low converted starch syrup (glucose DE value is below 20) is arranged, middle conversion starch syrup (DE value 38-42), the branch of high converted starch syrup (DE value 60-70).In invert syrup be to use more a kind ofly, also claim the standard syrup.
Summary of the invention
The technical problem that the present invention solves provides a kind of production method of lower-cost, corn starch syrup that raw material sources are abundant.Corn starch syrup of the present invention belongs to middle invert syrup.
For addressing the above problem, technical process of the present invention is as follows:
Concentrate → secondary decolourization filtration → secondary concentration → finished product starch → size mixing → saccharification → neutralization → decolorization filtering → ion-exchange first time → first time.Concrete steps are as follows:
The first step: size mixing
Add the W-Gum of pulverizing in size mixing jar (bucket), the soft water that adds about 80 ℃ evenly stirs, and reaches 22-24Be ＇ until starch concentration, and when production glucose, starch concentration is 12-14Be ＇, adds hydrochloric acid then, the sulfuric acid adjust pH is 1.8; For reducing or preventing that side reaction from taking place, oxalic acid commonly used replaces hydrochloric acid in the production.
Second step: saccharification
With the starch milk that mixes up, send into acidproof pressurization saccharifying tank with acid proof pump, steam is opened on charging limit, limit, after charging finishes, begins to boost under temperature 142-144 ℃ temperature constant state, whenever boosts 0.98 * 10
4Pa, the about 0.5min of the air valve that begins to rehearse is to discharge freezing air, and valve-off continues to boost until (2.7-2.8) * 10 when discharging white cigarette
4The pa vapor pressure, behind the constant voltage 3-5min, timely its DE value of sampling and measuring (the DE value is reducing sugar accounts for the syrup dry-matter with glucose meter a per-cent), when DE reached 38-40, saccharification finished.When DE does not reach 38-40, continue under temperature 142-144 ℃ temperature constant state, to boost, when reaching DE and be 38-40 till.
The 3rd step: neutralization
Open saccharifying tank after saccharification finishes saccharification liquid is blown into neutralization bucket, add the alkaline matter adjust pH to proteinic zero pour (general pH is 4.6-4.8).With most of hydrochloric acid or the sulfuric acid of neutralizing, protein coagulating is removed by filter, keep liquid glucose clear.
In order to improve clarifying effect, in and the time, the silicon bentonite that can be incorporated as amount of starch 0.1% is a finings.
The 4th step: decolorization filtering for the first time
Will in and liquid glucose be cooled to 70-75 ℃, regulate pH to 4.5 decolouring, add amount of starch then and be 0.25% Powdered Activated Carbon, with adding, pour plate and frame(type)filter press at last into or sealed horizontal round shape filter filters out sugared clearly filtrate with stirring 5min.
The 5th step: desalination is purified
The pellucid syrup that leaches decolouring is for the first time delivered to the ion-exchange filter bed and is carried out the desalination purification, carry out ion exchange reaction by positive monoyin and monoyang one cloudy four ion exchange columns, but radical on the active gene and the pellucid syrup same sex ion around it exchange, with the most ion remavals in the solution, realize that the desalination of pellucid syrup body is purified.
The 6th step: preliminary concentrating
Purification liquid glucose adjust pH to 3.8-4.2, is sent into to steam to draw and jar kept a vacuum tightness 66.66kPa (kPa represents to be no more than 0.98 * 10 at pressure more than the vacuum tightness
4Heating is concentrated into 28-31Be ＇ discharging under the situation of Pa.
The 7th step: decolorization filtering for the second time
To tentatively concentrate liquid glucose and carry out secondary decolourization, the secondary decolourization method is with for the first time identical, and requires repeatedly reflux and filter till the non-activity carbon particle, transfers pH to 3.8-4.2 again.
The 8th step: concentrate for the second time
Identical with preliminary concentration method, and before concentrating, need in liquid glucose, to add 40% bisulfite and receive solution, make that content of sulfur dioxide is 0.0015%-0.004% in the liquid glucose, bleach and a color-protecting function to rise.
The 9th step: the liquid glucose after will concentrating for the second time is evaporated to concentration and is the syrup finished product for 36-38Be ＇.
Positively effect of the present invention is: (1) is low with the W-Gum sugar making cost, and producing 1 ton of sugar needs the ton with corn 1.6-1.7, approximately needs the corn yield on 4 mu of ground, is 8 mu of output about ground and produce 1 ton of required beet of sugar; (2) the present invention refines sugar with W-Gum, and sugar yield is about 60%, and byproduct is Semen Maydis oil, wheat bran, protein etc., and feed and other byproduct can be provided again, and comprehensive production cost is also lower than import sucrose cost.Has very high promotional value with the W-Gum sugaring for this reason.
Embodiment
The present invention is concrete to be implemented as described in the summary of the invention, and those skilled in the art can implement fully according to the record of specification sheets.Need to prove:
In the 3rd step and the time, the alkaline matter of adding according to the first step acid that adds of sizing mixing decide, if then neutralize, as if then neutralizing it with lime carbonate with sulfuric acid with 10% sodium carbonate with hydrochloric acid.The sodium chloride that the former generates, molten being stored in the liquid glucose, but quantity is few, and it is little to influence local flavor, and the calcium sulfate that the latter generates is removed when filtering, and does not also influence local flavor.
