Abstract
This study addressed the issues of decreased white sugar quality and high production costs caused by crystallizer scaling at the Yunnan Mengpeng Sugar Factory.It aimed to explore efficient,economical,and environmentally friendly descaling technologies to enhance product quality and enterprise competitiveness.A systematic comparison was conducted between the physical descaling method(600～1 000 kg/cm2 high-pressure water jet)and the chemical descaling method(using KC-38 special cleaning additive and P-112 acid cleaner via acid-alkali boiling).The evaluation focused on cleaning effectiveness,equipment impact,cost-effectiveness,and production adaptability.The chemicals used complied with food industry safety standards,and the generated wastewater was treated to meet relevant discharge standards.The chemical descaling method significantly improved key white sugar quality indicators:the proportion of batches with≤5 black spots per pot increased from 93.51%to 99.36%;the proportion with≤5 yellow spots per pot rose from 72.28%to 97.58%;the proportion meeting the refined white sugar standard for water-insoluble impurities(≤10 mg/kg)jumped from 52.72%to 93.12%.The number of sugar pots requiring labeling for black/yellow spots plummeted from 77 to 3.Furthermore,the annual descaling cost decreased from 274 280 CNY to 64 741 CNY,a reduction of over 70%,eliminating the need for outsourced labor and reducing equipment maintenance costs.The chemical descaling method combining KC-38 and P-112 effectively removes stubborn tank scale,reducing sugar impurities at the source.It represents an optimal solution balancing cleaning efficiency,cost control,and equipment protection.Future efforts should focus on developing greener descaling agents,optimizing scale prevention technologies,and upgrading equipment and processes to promote more efficient and sustainable descaling technologies.关键词
