Abstract
The invention provides a syrup clarifying technology with a quicklime process. The syrup clarifying technology comprises the following steps: stirring the syrup; adding 5g of calcium hydroxide into each liter of syrup; keeping for 20 minutes, and quickly adding flocculants, namely chitosan and cationic polyacrylamide; slowly stirring for 2 minutes, and standing for 30 minutes; and finally, fetching the flocculation clear liquid. The applicant studies and finds that Zeta potential is closely related to the syrup clarifying technology, and the flocculation effect is better when the Zeta potential is lower; and multiple flocculants useful in the syrup clarifying technology with a quicklime process are selected, and the Zeta potential is minimum while the flocculation effect is the best when chitosan and cationic polyacrylamide are used as flocculants together.
Description
Technical field
The present invention relates to a kind of unslaked lime method clarified sugar juice technique.
Background technology
Flocculate and clarify is one of important operation in sugar industry.The worker that all the time refines sugar constantly is devoted to the improvement and perfection of flocculate and clarify technique and method.
Summary of the invention
The invention provides the unslaked lime method clarified sugar juice technique that a kind of flocculating effect is good.
The invention provides a kind of unslaked lime method clarified sugar juice technique, syrup is stirred, first adds calcium hydroxide with the add-on of 5g/L, keep 20 min, add rapidly flocculation agent chitosan and cationic polyacrylamide subsequently, slowly stir 2min, leave standstill 30 min, finally get flocculate and clarify liquid.
Preferably, the consumption of described chitosan is 0.015g/L.
Preferably, the consumption of described cationic polyacrylamide is 0.008g/L.
The applicant finds after deliberation, Zeta potential and juice,liming technique closely related, Zeta potential is lower, flocculating effect is better, the present invention selects operable multiple flocculation agent in unslaked lime method clarified sugar juice technique, finds, when adopting chitosan and cationic polyacrylamide jointly as flocculation agent, Zeta potential is minimum, and flocculating effect is best.
Embodiment
Following embodiment is convenient to understand the present invention better, but does not limit the present invention.Experimental technique in following embodiment, if no special instructions, is ordinary method.
embodiment 1
The preparation of 1 reagent
(1) preparation of brown sugar (Saccharum Sinensis Roxb.) retro-dissolved syrup: precise 100g brown sugar (Saccharum Sinensis Roxb.), is dissolved in 900mL distilled water, is slowly stirred to dissolves completely with magnetic stirring apparatus, the retro-dissolved syrup of obtained 10 ° of Bx, stand-by.
(2) preparation of cationic polyacrylamide: precise 2g cation polypropylene acid amide, is dissolved in distilled water, is slowly stirred to dissolves completely with magnetic stirring apparatus, finally dilution is settled in 1000mL volumetric flask, stand-by.
2 flocculating experiments
Get syrup 100mL in 250mL beaker, stir in constant temperature blender with magnetic force, first adding calcium hydroxide 0.5g, keep 20 min, add rapidly flocculation agent chitosan 0.0015g and cationic polyacrylamide 0.0008g subsequently, slowly stir 2min, leave standstill 30 min, finally get flocculate and clarify liquid, measure its colour.
The mensuration of 3 Zeta potentials
Liquid specific conductivity <50mScm to be measured is regulated with deionized water
-1, take out liquid to be measured and import in the pond of potentiometer, probe temperature is 25 DEG C, by its Zeta potential value of Zeta potential analysis-e/or determining, gets the mean value of 3 Duplicate Samples.
The applicant finds after deliberation, Zeta potential and juice,liming technique closely related, Zeta potential is lower, flocculating effect is better, the present invention selects multiple flocculation agent operable in unslaked lime method clarified sugar juice, finds, when adopting chitosan and cationic polyacrylamide jointly as flocculation agent, Zeta potential is minimum, and flocculating effect is best.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
