About

This is a blog that was launched in February 2021 with the goal of providing fundamental knowledge about the sugar processing industry. Our focus is on new developments and technologies in this field, with special attention paid to energy-saving concepts.


We welcome contributions from technologists who wish to share their knowledge and achievements in their organizations. By sharing new developments and technologies in the sugar industry and its auxiliary units, we can help others replicate these successes without reinventing the wheel.

Ion Exchange Resin Process in Sugar Refinery

Sugar refining is a process that requires removing impurities and colorants from raw sugar to produce pure and white sugar. One of the methods used for sugar decolorization is the ion exchange resin (IER) process, which is based on the principle of exchanging ions between a solution and a solid resin. In this blog post, we will explain how the IER process works in sugar refinery, what are its advantages and challenges, and what are the best practices for optimizing its performance. The IER process in sugar refinery consists of passing sugar liquor through a bed of resin beads that have functional groups attached to their surface. These functional groups can either attract or repel certain ions in the solution, depending on their charge and affinity. For example, a strong acid cation (SAC) resin has sulfonic acid groups that can exchange hydrogen ions (H+) with other cations such as sodium (Na+), calcium (Ca2+), or magnesium (Mg2+). Similarly, a strong base anion (SBA) resin has quatern...

Carbonation Process in Sugar Refinery

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...

Rotary Pressure Filters Sugar Refinery

Rotary pressure filters are extensively utilized in the sugar industry to filter carbonated liquor , a solution consisting of sugar and lime that has undergone carbonation to eliminate impurities. These filters are known for their ability to conduct both pressure filtration and cake washing within a single unit. A rotary pressure filter comprises a cylindrical drum that rotates at a gradual pace either horizontally or vertically. The drum is partitioned into multiple sections, each equipped with its individual filter medium, commonly made of cloth, and designated process zone. The drum is enclosed within a pressure vessel, which contains the feed slurry, wash liquid, and filtrate. Rotary pressure filter involves several key steps for proper filtration- Distribution: Carbonated liquor, containing a mixture of sugar crystals and molasses, is evenly distributed onto a filter medium (typically a cloth) that covers a rotating drum. The drum is divided into compartments, each filled with t...
