Carbonation Process in Sugar Refinery

By
Image
The carbonation process is a widely used method for refining sugar from raw sugar melt. It involves the reaction of calcium hydroxide and carbon dioxide to form calcium carbonate, which precipitates and removes impurities and colorants from the sugar solution. The carbonation process has several advantages, such as low capital and operating costs, high color and turbidity removal efficiency, low sugar loss and environmental friendliness. In this blog post, we will explain the main steps and equipment involved in the carbonation process, as well as some tips and best practices to optimize its performance. The goal of the carbonation process is to eliminate impurities that make raw melt liquor cloudy. Carbonation is typically used in refineries before any decolorizing process. It has a positive effect on sugar liquors, reducing color by 40-50% and ash content by 20-25%. Lime and carbon dioxide are added to the sugar liquor to create calcium carbonate precipitates that absorb impurities a...

Ion Exchange Resins in Sugar Refining: Polishing Liquor for Purity

By
After carbonation has done its job — removing suspended solids and reducing color — sugar liquor still contains dissolved ions and trace colorants that can interfere with crystallization and final product quality. That’s where ion exchange resins come in. Acting like molecular magnets, these resins polish the liquor by swapping unwanted ions for more desirable ones, helping refineries achieve the clarity and consistency needed for premium sugar. Let’s explore how the process works, what types of resins are used, and why this step is critical in the refining sequence. 🧲 What Are Ion Exchange Resins? Ion exchange resins are synthetic polymer beads designed to attract and hold specific ions from solution. They work through a reversible chemical exchange — trading ions in the resin for those in the sugar liquor. There are two main types: Cation exchange resins : Remove positively charged ions like calcium (Ca²⁺), magnesium (Mg²⁺), and iron (Fe²⁺), typically exchanging them for sodium (N...

Vacuum & Condenser System Overview

By
In the sugar industry, vacuum systems are used to create and maintain a low-pressure environment inside a vacuum pan during the sugar boiling process. The vacuum system is an essential part of the sugar refining process, as it allows the sugar to be boiled at a lower temperature than it would under atmospheric pressure, which helps to prevent caramelization and degradation of the sugar. The vacuum system typically consists of vacuum pumps , which are used to remove air, vapor and other gases from the vacuum pan, and a condenser system which is used to remove the water vapor that is produced during the sugar boiling process. The vacuum pump is typically a liquid ring pump or a rotary vane pump, and is capable of creating a vacuum pressure of several hundred mmHg gauge. As the sugar is heated and boiled in the vacuum pan, water vapor is produced, which is removed from the pan by the vacuum pump. The water vapor is then condensed back into a liquid by the condenser system, which typically...
