Description
Sugar making technology by using maize raw milk of the present invention belongs to the processing method that adopts corn primary-pulp to refine sugar.
The available technology adopting corn cook sugar usual method be, corn is isolated plumule after fragmentation, fiber, compositions such as protein are made starch slurry, again by starch slurry through liquefaction, links such as saccharification are made liquid glucose.Process procedure is loaded down with trivial details, the artificial investment of equipment is big, cross sieve remove slag and centrifugal separation processes in, cause partial starch to run off, influence sugar yield, the process procedure process is many, a large amount of waste water is discharged, cause environmental pollution, its technical process is: corn → soak → pulverize → take off embryo → mistake sieve to remove slag → 101 ℃ of-105 ℃ → laminar flows of magma → centrifugation protein → starch slurry → adjusting PH5.5-6.0 → one time steam ejection liquefaction temperature keep → second spraying liquefaction temperature 〉=135 ℃ → dodge cold → middle temperature liquefaction temperature to regulate PH6-6.5 → saccharification temperature for 85 ℃-95 ℃ and regulate PH4.2-4.5 → press filtration → liquid glucose for 59 ℃-62 ℃.
The purpose of sugar making technology by using maize raw milk of the present invention is to overcome above-mentioned defective and design a kind of sugar making technology by using maize raw milk, adopts corn to take off directly to pulverize behind the embryo to make corn primary-pulp, liquefy through second spraying, reach corn primary-pulp and manufacture liquid glucose, technology is short, and cost is low, reduce discharge of wastewater, the sugar yield height, the artificial less investment of equipment, free from environmental pollution, W-Gum does not run off, and power consumption is low.
Sugar making technology by using maize raw milk of the present invention takes following scheme to realize, corn taken off directly to pulverize behind the embryo make magma, get magma and cook liquid glucose, its technical process is, corn → immersion → pulverizing take off embryo → magma → get slurry regulate PH5.5-6.0 → one time steam ejection liquefaction temperature be 102 ℃ of-105 ℃ → laminar flow → second spraying liquefaction temperatures be 〉=135 ℃ → dodge cold → middle temperature to liquefy and be 85-95 ℃, regulate PH6.0-6.5 → saccharification and regulate PH4.2-4.5, temperature is a 59-62 ℃ → plate-and-frame filter press filtration → liquid glucose.Operating process of the present invention is, at first the method for corn with selection by winnowing and wet concentration purified, remove impurity in the corn, corn is sent into steeping tank, adopting concentration is 0.25-0.5% sulfurous acid water logging bubble 48-72 hour, makes corn grain softening, and water ratio is more than 40%, get corn grain after the immersion and send into double wedge and gall and be broken into fritter, enter and carry out germ separation in the floating groove.The corn fragment of isolating plumule is sent into emery wheel grind, promptly become corn primary-pulp.Get corn primary-pulp and send into the jar of sizing mixing, add soda ash and regulate pH value 5.5-6.0, press the pure starch of 0.4-0.6 liter/ton then and add alpha-amylase, stir, by being pumped into Jet liquefier, 102 ℃-105 ℃ of controlled temperature, carry out steam ejection liquefaction one time, control discharge port feed temperature was held time 4-5 minute through keeping jar at 100 ℃-102 ℃, entered the laminar flow jar, 100 ℃ of controlled temperature, control input speed simultaneously, guarantee 45-60 minute laminar flow time, make feed liquid obtain fully liquefaction, feed liquid enters second spraying liquefaction through the laminar flow jar, temperature is controlled at more than 135 ℃, and through the feed liquid of second spraying liquefaction, tangent line enters and dodges anxious cooling tank, reach gas-liquid separation, feed temperature is reduced to 85 ℃-95 ℃, and feed liquid is sent into saccharifying tank, presses 2-8kg/50M
3Liquefier, warm amylase was kept 30 minutes in the adding.Feed liquid obtains liquefaction fully, and liquefier is regulated pH value to 4.2-4.5 with hydrochloric acid, and reducing temperature simultaneously is 59 ℃-62 ℃, carries out saccharification.The consumption of saccharifying enzyme is pressed 100-150 units/gram starch and is added, and saccharification time is 32-38 hour, through the raw spirit check, determines that no dextrin exists, and saccharification finishes, and saccharification liquid filters through plate-and-frame filter press, obtains cleaner liquid, is liquid glucose.
The effect of sugar making technology by using maize raw milk of the present invention, be that technology is simple, easy to operate, energy consumption is low, the sugar yield height, waste water eliminating amount is few, reduce the contaminated wastewater environment, equipment and investment in human resources are little, and cost is low, improve sugar yield 5-8%, adopt and take off size mixing twice steam ejection liquefaction and saccharification of embryo behind the corn soaking and obtain liquid glucose.
Sugar making technology by using maize raw milk of the present invention will describe in further detail in conjunction with the embodiments.The direct pulverizing made magma after the present invention adopted corn to take off embryo, utilize corn primary-pulp to manufacture liquid glucose, its technical process is: corn → immersion → pulverizing take off embryo → corn primary-pulp → adjusting PH5.5-6.0 → one time steam ejection liquefaction temperature be 102 ℃ of-105 ℃ → laminar flow → second spraying liquefaction temperatures be controlled at 〉=135 ℃ → dodge cold → middle temperature liquefaction temperature at 85-95 ℃, regulate PH6.0-6.5 → saccharification and regulate pH value 4.2-4.5, temperature is controlled at 59-62 ℃ → plate-and-frame filter press filtration → acquisition liquid glucose.Operating process of the present invention is: the method for at first using selection by winnowing and wet concentration, remove the impurity in the corn, corn is sent into steeping tank, adopting concentration is 0.25-0.5% sulfurous acid water logging bubble 48-72 hour, make corn grain softening, water ratio is more than 40%, the corn grain of getting after the immersion is sent into the double wedge mill, be broken into fritter, enter and carry out germ separation in the floating groove, the corn fragment of isolating plumule is sent into emery wheel to grind, obtain corn primary-pulp, corn primary-pulp is sent into the jar of sizing mixing, add soda ash and regulate pH value 5.5-6.0, press the pure starch of 0.4-0.6 liter/ton and add alpha-amylase, feed liquid stirs, by being pumped into Jet liquefier, temperature is controlled at 102 ℃-105 ℃, carries out steam ejection liquefaction one time, and control discharge port feed temperature is at 100 ℃-102 ℃, held time 4-5 minute through keeping jar, enter the laminar flow jar, at 100 ℃, control input speed simultaneously in laminar flow jar holding temperature, guarantee 45-60 minute laminar flow time, make feed liquid obtain fully liquefaction, feed liquid enters second spraying liquefaction through the laminar flow jar, and the second spraying temperature is controlled at more than 135 ℃, feed liquid through second spraying liquefaction, tangent line enters and dodges anxious cooling tank, reaches gas-liquid separation, and feed temperature is reduced to 85 ℃-95 ℃, feed liquid is sent into saccharifying tank, press 2-8kg/50M
