The French manufacturer HYET Sweet requires an extremely stable pump to move artificial sweeteners.
Aspartame is primarily derived from two naturally occurring amino acids that are chemically combined. Although its constituents – aspartic acid, phenylalanine and methanol – are found naturally in food, a complex synthesis procedures is required to obtain the white, very pure aspartame. The aspartame is cleaned in several reaction stages using a special crystallisation procedure and separation method.
A circulation pump supplies a falling film evaporator between stage 1-2 to reduce the amount of water in the product as far as possible. After a defined period of time, the 2.6-fold concentrated aspartame is fed to the next process stage. As the pumps are used at the start of the process chain, high service lives are increasingly important for 24/7 continuous pumping operations. Production failures or malfunctions lead to high business costs.
