A Better Solution for Cooling Sugar, DANISCO SUGAR, KOPINGEBRO, SWEDEN

摘要

Danisco Sugar is the fourth largest sugar producer in Europe. From 1997-2000, the Danisco plant located in the small town of Kopingebro in the south of Sweden increased its capacity by 40 percent, producing 85,000 kg/hr of granulated sugar. With the increased rates, Danisco found that the cooling capacity of their existing equipment was no longer sufficient to meet their needs. The sugar temperature had increased to approx. 35-40 deg C which created a problem since the recommended temperature to prevent caking and maintain product quality in storage is below 30 deg C. Until then, the traditional ways of cooling sugar included drum coolers or fluid bed coolers that use large amounts of air and energy to provide the necessary cooling. The engineers at Danisco were on the lookout for a more cost effective solution and decided to evaluate the Bulkflow Heat Exchanger. This technology had just been introduced to the sugar industry after many years of cooling other types of free flowing bulk solids such as plastics, detergents, fertilizers and chemicals.
