France sugar plant realizes efficiencies with Solex cooler

In late 2020, Cristal Union had a decision to make. The company's sugar beet plant in Bazancourt, France was operating a vertical disk cooler that was nearing end of life. The agro-industrial co-operative group could either swap out the unit with another direct-contact cooler, or look at other options — namely an indirect method that uses thermal conduction instead of convection.

More recently, this case study was picked up in the International Sugar Journal, where Jean-Marc Reichling, Global Sales Director at Solex, shared details of the unit that was installed. Some of the topics covered included:

Design considerations: For example, the Bazancourt installation included a closed-loop circuit for the cooling water, thereby eliminating the need for external water supply.

Process conditions: Solex needed to cool the sugar to a consistent temperature of 30°C. So a water temperature control module was added that allowed plant operators to adjust this temperature, when necessary. 

Successes: A dry cooler was added with the chiller to minimize energy consumption. So that when the ambient air dropped below 15°C during the sugar campaign, only the dry cooler would operate; between 15 C to 28°C and both the dry cooler and chiller would work, and; at temperatures above 28°C, only the chiller would operate.
