Temperature control during grinding stage
The most important part of cocoa processing is the grinding stage. This involves the use of massive and powerful motors that drive these grinders and different groups of motors by a frequency converter which is controlled by the PLC. This leads to waste emission which needs to be cooled from time to time and ensure the temperature is maintained. The temperatures during this process can reach up to 45 °C. This requires consistent and precise cooling and maintenance of ambient temperature and to achieve this Cargill’s Zaandam plant relies on over fifty units of Blue e+ cooling units.
Optimum maintenance for maximum reliability
The requirement for reliable and powerful climate control solutions prompted Cargill to sign a contract with Rittal for maintenance and precision in delivering reliable and efficient cooling solutions. Additional cooling units were installed in Cargill’s production sequence to address this need. In sync with digital Life Cycle Maintenance (LCM), Rittal maintains all the cooling units, and timely replacements, repairs, and services are provided by the Rittal Service Team. This service is in adherence to the service agreement with Cargill.
Additionally, all the cooling parts that need frequent replacements are overhauled by Rittal to ensure optimum maintenance and maximum reliability is achieved. They ensure to stock the ready-to-use cooling units consistently to always meet the requirements for sudden replacement.
“Rittal’s service technicians not only know the Rittal products inside out, but they are also well informed about the applicable safety regulations,” says John Deijle, Work Preparation, Cargill Nederland. “The combination of Rittal products and service makes a valuable contribution to process reliability.”
A high level of energy efficiency is achieved because of the high level of maintenance and consistency in service. The Rittal service team conducts regular assessments with their industry experts to ensure that cooling units are replaced on time and coolants are disposed of whenever required, with the necessary documentation.
