Caloris Presents Low-Spore Powder Process at 2018 Spore Seminar

Easton, Md. — Caloris Engineering presented its patent-pending low-spore powder process at the 2018 U.S. Dairy Industry Spore Seminar in Morro Bay, Calif., on March 1.

Caloris Sales Manager Bruce Skinner gave the presentation at the event, which was sponsored by the U.S. Dairy Export Council and the National Dairy Council.

The Caloris Low Spore Process provides a routine and robust process for consistent production of high quality low-spore milk powders each and every day. The process utilizes standard operating procedures that are straight forward and repeatable, ensuring a consistent low-spore milk product quality.

Many milk powder processors face the challenge of achieving consistent daily production of milk powders with low spore counts. The presence of a nominal level of spores in milk powders is difficult to avoid because of their presence in the incoming raw milk supply.

A critical challenge is the exponential growth in spore counts to unacceptable levels that develops over the course of a daily production cycle due to growth of biofilms. In particular, certain sections of the evaporator provide ideal growth conditions for biofilms formed by vegetative bacteria, and after a maturing period of approximately 10 hours, those biofilms begin to contaminate the milk they contact for the remainder of the evaporator production run.

In the past two years, two dairy processors have worked with Caloris to install new evaporator systems incorporating the patent-pending Caloris Low-Spore Process, and are now consistently and routinely producing high quality low spore milk powders while maintaining continuous and uninterrupted operation of their spray dryer systems.

The key to the Caloris Low Spore Process is well-timed and rapid evaporator system Clean-In-Place (CIP) cycles, which eliminates 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 does not increase daily CIP time and allows for these CIP cycles to occur without interrupting the powder production of the spray dryer system.

“The concept struck us as simple, robust, and repeatable,” said one Caloris customer. “We could clearly eliminate the risk of operating with the presence of mature biofilms that, in a traditional evaporator system, serve as a source for contamination of the milk product with spores.”
