Summary of the invention
The objective of the invention is to propose a kind of production method of Dian Fentang, to solve the many technical problems of Dian Fentang impurity that present production method is produced.
The present invention solves the problems of the technologies described above by the following technical programs, reaches purpose of the present invention.
A kind of production method of Dian Fentang, with the W-Gum is raw material, the method that adopts zymin that described W-Gum is hydrolyzed is produced described Dian Fentang, the production process of described Dian Fentang comprises batching, steam ejection liquefaction, saccharification, decolouring, ion-exchange and concentrates, in the production process of Dian Fentang, use the filtration unit of different meshes to filter out impurity.
The present invention uses the filtration unit of different meshes to filter out impurity in the production process of Dian Fentang, and the impurity that a production step is produced does not enter next production stage as far as possible.Present Dian Fentang production technology does not have to adopt so intensive level to filter, and the precision of the filtration unit that adopts is so not high, generally their filtering accuracy can not effectively be tackled for some comparatively tiny impurity at 20-100 μ m, causes product to contain tiny impurity.One aspect of the present invention can reduce impurity and enter next step operation, equipment is effectively protected, and improved the working efficiency of each equipment, can guarantee not produce in the product contaminating impurity on the other hand.
Further, in described production process at Dian Fentang, use the filtration unit of different meshes to filter out impurity, be before described steam ejection liquefaction, behind described steam ejection liquefaction and before the described saccharification, before described decolouring back and described ion-exchange, after described ion-exchange and before described the concentrating, use the filtration unit of different meshes to filter out impurity respectively; The order number of the filtration unit that uses before described steam ejection liquefaction is greater than the order number of the filtration unit that uses behind described steam ejection liquefaction and before the described saccharification; The order number of the filtration unit that uses behind described steam ejection liquefaction and before the described saccharification is greater than the order number of the filtration unit that uses before described decolouring back and described ion-exchange; The order number of the filtration unit that uses before described decolouring back and described ion-exchange is greater than the order number of the filtration unit of use after described ion-exchange and before described the concentrating.In the production process of Dian Fentang, the order number of the filtration unit of use is first big after small, can produce smoothly like this, does not need extra power.At present, some bigger impurity may stop up production unit, thus the present invention earlier with the order number bigger with these Impurity removals.In addition, the viscosity of liquid glucose is also bigger in the production process before the saccharification, filter relatively difficulty with the less strainer of order number, and comparatively tiny impurity exists possibility smaller in the production process before the decolouring, so be fit to use earlier the big filtration unit of order number, the little filtration unit of order number is used in the back.These filtration procedurees all are by carrying with the pump slurry liquid, pass through filtration unit voluntarily after the certain pressure difference is arranged, so do not need extra power.
The order number of the filtration unit that uses before described steam ejection liquefaction is 100-150 μ m.The impurity that uses filtration unit to filter out before described steam ejection liquefaction is impurities in raw materials.The filtration unit that uses before described liquefaction before steam ejection liquefaction is pressure filter or mesh bag.The impurity particle that exists before the steam ejection liquefaction is bigger, generally greater than 100-150 μ m, therefore selects the pressure filter of 100-150 μ m more suitable.
The order number of the filtration unit that uses behind described steam ejection liquefaction and before the described saccharification is 20-50 μ m.The sex change protein floculation that the impurity that uses filtration unit to filter out behind described steam ejection liquefaction and before the described saccharification is zymin to be hydrolyzed and to produce in the process W-Gum.The filtration unit that uses after described flash distillation and before the described saccharification is vacuum drum strainer or plate-and-frame filter press.
Successively use the filtration unit of two kinds of different meshes to filter out impurity before described decolouring back and described ion-exchange, the order number of the filtration unit that uses earlier is 20-50 μ m, and the order number of the filtration unit that use the back is 1-3 μ m.The impurity that the filtration unit that elder generation uses filters out is the gac smalls that produces in the decolorization.The filtration unit that use the back filters out more tiny impurity, is in order further to remove the gac smalls.The described filtration unit that uses earlier is a candle filter, and the filtration unit that use described back is an accurate filter.
Successively use the filtration unit of two kinds of different meshes to filter out impurity after described ion-exchange and before described the concentrating, the order number of the filtration unit that uses earlier is 1-3 μ m, and the order number of the filtration unit that use the back is 1-0.45 μ m.The described filtration unit that uses earlier is the cardboard strainer, and the filtration unit that use described back is a film filter.Use earlier the cardboard strainer, film filter is used in the back, and energy protective membrane strainer like this makes film filter avoid the destruction of bigger impurity.Use the cardboard strainer earlier, film filter is used in the back, mainly is the ion exchange resin impurity that filters out the fragmentation that forms in the ion exchange process.
Method of the present invention simple effectively detects proof through vacuum diaphragm suction filtration method, and the Dian Fentang that obtains through present method production is at 0.45 μ m rank inclusion-free.
