Success Story: Reduced pH Electrode Consumption in Cane Sugar Refining

The electrodes now last 3–4 weeks as opposed to < 1 week with previous brands!
One of the most common problems in sugar refining processes, especially during carbonatation, is the continual electrode maintenance required to ensure smooth process control. METTLER TOLEDO problem-solver pH InPro2000 electrode for harsh conditions offer longer serviceable life and needsmuch less attention.
Sugar industry in the UK
UK sugar production is dominated by two national sugar makers. The largest concern concentrates on the processing of the UK's entire sugar beet crop of around 9 million tons. The other company, with a more international commitment and a more diversified product portfolio, is one of the largest producers of cane sugar in Europe. Apart from white sugar manufacture traditionally covers a wide variety of cane sugars, including the dark soft types much favored for baking purposes, e.g. Demerara, Muscovado, Turbinado, as well as treacle and syrups.

Problems with high electrodeconsumption
During the refining process, the pH electrodes have to endure extremely hostile environments with high temperatures of over 90 °C/194 °F as well as the presence of very abrasive solids. Our customer was experiencing instable readings and high electrode consumption due to these harsh conditions. This had in the past resulted in the electrodes lasting only 1 week before needingto be replaced……
