Caloris Customer Finds Success with Low-Spore Milk Powders

In the May edition of its newsletter, Horizons, Hoogewegt Group details a spike in demand for low-spore milk powders and chronicles the success of its collaboration with Lone Star Dairy Products (LSDP) to produce these powders. Caloris installed its patented low-spore powder production system at the LSDP plant in Canyon, Texas, in 2017.

The key to the Caloris Low Spore Process is well-timed evaporator system CIP cycles, which eliminates operation with the presence of mature biofilms in the evaporator system before they begin to contaminate the milk product with spores. The configuration of the Caloris Low Spore Process allows for these CIP cycles to occur without interrupting the powder production of the spray dryer system.

The installation at LSDP garnered a 2018 Breakthrough Award from the American Dairy Products Institute for its ability to “consistently and routinely produce high-quality, low-spore milk powders.”

Caloris is proud that this initiative has resulted in success for LSDP and Hoogwegt. We look forward to helping others produce low-spore powders using our unique process technology.
