Steam for preparation phase 1, thermal oil for phase 2
Callens’ steam installation has been an integral part of this customer’s boiler room for a long time. It peels the potatoes flawlessly before they are transformed into croquettes, duchess potatoes, mashed potatoes and more. A steam installation of 4 tons steam per hour guarantees an efficient peeling process. Afterwards, the potatoes undergo various thermal treatments such as frying, mashing, … which are incinerated by a thermal oil boiler with a capacity of 1 million Kcal per hour. However, the customer needed more.
“We need reliable machines every day and every hour, just like we need reliable suppliers with an excellent service to support our growth both in quality and quantity. That’s why, once again, we chose Callens to engineer and execute this project.”, says the Project Director.
Expansion calls for additional capacity of thermal oil and a piping upgrade
A brand new thermal oil boiler with a capacity of 2 million Kcal per hour now sustains the production expansion. Besides connecting the installation to the existing boiler room, the Cauls had a second challenge to tackle: upgrading the piping network to the next level. The challenge was completed successfully by removing all the different types of pipes that were connected to the balance tank, and replacing them by collector pipes.
Ultimately, Optimum by Callens designed and installed a steam boiler using baking fumes, prepared and installed by the Cauls.
Thermal oil boiler:
- Capacity: 2 million Kcal/h
- Operating pressure: 8 barg
- Max. temperature: 300 °C
Steam from baking fumes:
- Capacity: 10 tons steam/h
- Operating pressure: 18 barg
- Working pressure: 16 barg
- Combustion efficiency: 96%
