Microwave measuring procedure during the sugar extraction Micro-Polar Brix

摘要

A microwave measuring system for controlling the crystallization process is described. This measuring system, based on the most modern microwave engineering determines on-line the Brix content, respectively the density both in sugar solutions of arbitrary concentrations and in crystal suspensions. Thereby; a continuous measurement is possible during the entire crystallization process.rnThe new measuring system works with different sensors, which are introduced here. Measurements in pipelines (inline), crystallizers and in other process operated plant parts are possible with these sensors.rnTypical application problems such as incrustations, abrasion, purity dependencies and pause detection between two crystallization processes are discussed and solution suggestions are shown by means of Micro-Polar Brix.rnBeside the accurate, reliable, and precise measurement of A, B, and C products of sugar beet and sugar cane, simple operation, calibration, and maintenance-free operation are also of great importance in times of process optimization and cost-efficiency. The possibility of automatic calibration without a PC is being considered for this case.rnBeing of vital interest, the topic of electromagnetic compatibility of microwave radiation is being studied and clarified on the basis of mobile phones, where the assigned microwaves of a very small power are absolutely harmless for humans and the environment.
