Abstract

This study focuses on improving energy efficiency in beet sugar extraction by controlling raw juice extraction and reducing water (“draft”) added during the process, which increases steam consumption. It proposes precise draft calculation methods using real-world data. The research examines production line parameters before and after optimization in a factory processing 3000 tons of beet sugar daily. Improvements include raising pulp dry matter to 25% and cutting raw juice draft to 107%, leading to significant exergy loss reduction and efficiency gains. The study highlights the importance of specific temperature ranges for optimal outcomes and substantial energy savings through increased pulp dry matter and better temperature control, resulting in lower gas consumption and cost savings. Statistical tests confirm the effectiveness of these measures. Overall, the study emphasizes the critical role of optimization for energy, economic, and environmental benefits in sustainable sugar production.

甜菜糖厂原汁提取的能源与用能分析

本研究的重点是通过控制原汁提取和减少过程中增加蒸汽消耗的水（“草案”）来提高甜菜糖提取的能源效率。它提出了精确的草案计算方法，使用现实世界的数据。本研究考察了一家日加工3000吨甜菜糖的工厂优化前后的生产线参数。改进包括将纸浆干物质提高到25%，将原汁draft降低到107%，从而显著降低了火用损失并提高了效率。该研究强调了特定温度范围的重要性，通过增加纸浆干物质和更好的温度控制来实现最佳结果和大量节能，从而降低气体消耗并节省成本。统计检验证实了这些措施的有效性。总体而言，该研究强调了可持续糖生产中能源、经济和环境效益优化的关键作用。
