Description
Vynález se týká způsobu přípravy čeřicí směsi k čištění cukerných roztoků při výrobě cukru.BACKGROUND OF THE INVENTION The present invention relates to a process for preparing a fining composition for purifying sugar solutions in sugar production.
Dosud známá způsoby přípravy čeřicí směsi k čištění cukerných roztoků, které používají pro tento účel saturační kal a vápenné mléko, tyto dvě složky pouze smísí a dávkují do cukerného roztoku. Vzduch k oxidaci je pak přidáván až v místě nejnižší koncentrace vápna v cukerném roztoku v procesu epuraoe. Tato koncentrace obvykle nepřesahuje 2 % CaO, výjimečně 3 % CaO. Tím je reakční rychlost tvorby CaOg nízká a reakční rovnováha posunuta směrem k CaO. Kromě toho jsou v místě přídavku vzduchu přítomny ve štávách mechanické částice sraženiny a makrokoloidy; část vzniklého CaCOg je pak spotřebována ne jejich destrukci. Výsledkem je malá účinnost odbarvení cukerných stáv, tímto způsobem do 30 %.The prior art processes for preparing the fining mixture for purifying sugar solutions, which use saturating sludge and lime milk for this purpose, merely mix and dispense the two components into the sugar solution. The oxidation air is then added at the lowest lime concentration in the sugar solution in the epuraoe process. This concentration usually does not exceed 2% CaO, exceptionally 3% CaO. As a result, the reaction rate of CaOg formation is low and the reaction equilibrium is shifted towards CaO. In addition, mechanical precipitate particles and macrocolloids are present in juices at the point of addition of air; part of the resulting CaCO3 is then consumed not for their destruction. As a result, the decolorizing efficiency of the sugar barrels is poor, up to 30% in this way.
Výše uvedené nedostatky jsou odstraněny způsobem přípravy čeřicí směsi k čištění cukerných štáv podle vynálezu, jehož podstatou je, že se smísí saturační kal s vápenným mlékem při teplotě 5 až 85 °C a po smíchání nebo současně při směšování se směs saturačního kalu a vápenného mléka probublává vzduchem při tlaku 0,03 až 0,4 MPa. Probublávání směsi vápenného mléka a saturačního kalu vzduchem posune reakční rovnováhu směrem k CaOg a současně stoupne reakční rychlost. Tím stoupne efekt odbarvení zpracovávaných cukerných roztoků na 40 až 45 % a jakost Štáv se zvýší.The above drawbacks are overcome by the process for preparing a clarifying mixture for the purification of sugar juices according to the invention, which consists in mixing the saturating sludge with lime milk at a temperature of 5 to 85 ° C and bubbling the mixture of saturating sludge and lime milk air at a pressure of 0.03 to 0.4 MPa. Bubbling air through the mixture of lime milk and saturation sludge shifts the reaction equilibrium towards CaOg while increasing the reaction rate. This increases the decolorizing effect of the processed sugar solutions to 40-45% and the juice quality is increased.
Konkrétně lze provést způsob přípravy čeřicí směsi k čištění cukerných štáv například takto» část zahuštěných kalů z druhé saturace se kontinuálně mísí s vápenným mlékem určenýmIn particular, a process for preparing the fining mixture for the purification of sugar juices can be carried out, for example, a portion of the concentrated sludge from the second saturation is continuously mixed with the lime milk to be
