Out of all of the applications where you can find a Viking pump, chocolate may be the most delicious. Viking pumps are the pump of choice for the processing, transfer, and recirculation of chocolate. The chocolate production process can be simply described with these steps: cacao beans are roasted and ground, then mixed with oils into a semi-liquid. This early stage is known as "bitter" chocolate. From here, sugar can be added to make "sweet" chocolate - milk can be added for "milk" chocolate - and if the chocolate has been thinned down is called chocolate liquor.
