Background technology
At present, domestic cane sugar manufacture production technology mainly has lime method, sulfurous method and carbon according to the difference of clarification process
Acid system, the clarifying treatment step in above-mentioned strick precaution mainly has three processes：Heat sugarcane juice, addition fining agent, precipitation and separation.And it is simple
Single practicality fining agent removes the impurity such as the non-sugar ingredient in initial syrup, while reducing the colourity and turbidity of syrup, but still suffers from
Percent of decolourization is low, non-sugar ingredient clearance is low, fining agent consumption is big, influence mouthfeel the problems such as, during especially with sulfurous method,
Unavoidably there is SO2Remain in juice, in follow-up boiling process, can be adsorbed by sucrose crystal, wrap up enter sugar crystalline substance
Internal portion, causes sugar to contain SO2, influence sugar safety.Therefore, a kind of juice sugaring work with more securities is needed badly at present
Skill.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantage that at least will be described later.
Juice method is clarified without sulphur it is a still further object of the present invention to provide one kind, its sugar produced is free of SO2, effectively drop
The chromatic value and turbidity value of low product, improve purity and concentration.
Juice method, bag are clarified without sulphur there is provided one kind according to object of the present invention and further advantage in order to realize
Include following steps：
Step 1: by cane milling, filtering, obtaining bagasse and sugar-cane juice, sugar-cane juice connects addition under stirring
Phosphoric acid, makes phosphoric acid concentration reach that every L sugar-cane juices have 200mg phosphoric acid, while it is 7~8 to add milk of lime to pH, is heated to boiling,
Sedimentation separation obtains subsider juice；
Step 2: by bagasse be transferred to temperature be 100 DEG C, steam pressure be that to carry out steam under conditions of 1~2MPa quick-fried
Broken, the steam blasting time is less than 0.01s, and the dwell time is 1min, discharges pressure to normal pressure every 15s afterwards, is discharged into every time
The gross weight of the bagasse of normal pressure is 25%, collects the bagasse after steam blasting；
Step 3: spraying composite enzyme solution to the bagasse surface after steam blasting, surface is infiltrated to dripping, protect
10min is held, then subsider juice is mixed, is squeezed, filtered, obtain enzymolysis liquid, wherein, the mass fraction of composite enzyme solution
