Scheduling filter cleaning was found to be one of the major concerns. The maximisation of the throughput via scheduling was approached by data integration and modelling. Linear regressions of the process parameters were implemented in volume space, which allows for the prediction of the remaining run duration of each filter. These predictions are continually used as an input to an algorithm that creates a schedule. The calculations are conducted in the cloud on real-time data and the predictions reported to a web-based user interface for the plant operator to use.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"138 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89914277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article evaluates the hallmarks of a mill that lead to efficient performance, from cane harvesting through the individual unit operations to the production of sugar, ethanol and energy. The process of cane harvesting and transport impacts the juice purity, which has a major impact on sugar recovery. Conditions in processing affect losses and color formation and the aim is to minimize temperatures and residence times in the process steps, while also minimizing the opportunities for any micro-biological losses. High massecuite exhaustions in the pan house are vital in this respect and affect steam requirements due to lower recycling in the pan house. The requirements for maximum export power include reducing process steam usage and low processing energy requirements.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"33 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81905255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to improve the understanding and control of sucrose solubility in molasses it is believed that it is necessary to firstly gather experimentally detailed and consistent solubility and composition data. Secondly, the mathematical description of sucrose solubilities in molasses should be reconsidered. In the contribution data on 49 different molasses are described. The data show significant variation in both the sucrose solubility and the composition of the nonsucrose components. Current models to describe the solubility are discussed in light of thermodynamical considerations and their success in representing the data gathered.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"60 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76051410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrary to industries with high-temperature energy consumption (e.g. steel or cement industries), the sugar industry uses relatively low-temperature energy (except for milk of lime production). To reach low-carbon/carbon-free reduction, the sugar industry will have to re-design its complete energetic scheme. The panorama of solutions answering the aforementioned questions are reviewed. Among these solutions, the optimization of the process by using existing well-known technologies is the 1st option: mechanical vapour re-compressors (MVR), heat pump, cogeneration technologies, by-product anaerobic digestion, etc.\u0000\u0000Combining these solutions will support the sugar industry to decrease significantly its specific energy consumption. As a reference, today’s sugar factories have a specific consumption between 900 to 1200 kWh of primary energy per tonne of sugar. A target for the future is to decrease the specific primary energy consumption to 620 kWh per tonne of sugar (without pulp drying). This new benchmark could be even improved in the case of using low-carbon electricity imported from the grid. How far could one go into the decarbonization of beets sugar factories? Is the objective of having net-zero emissions for sugar production realistic?","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"43 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85853596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
