A study at the University of Florida took a look at tank cleaning foodgrade applications and determined that the procedures do not always meet the desired outcome, said Paul Winniczuk who conducted the study. Winniczuk discussed the study at the National Tank Truck Carriers Tank Cleaning and Environmental Council Seminar March 30-31 in San Antonio TX, as well as at an April 20-22 meeting of the International Milk Haulers Association in Phoenix AZ.
In the tests using 176 tanks that had contained a variety of products, including juices, oils, milk, eggs, and peanut butter, Winniczuk determined that tanks continued to have bacteria in their interiors even with the university's controlled wash procedure. Samples were collected from throughout the tanks and from tank components.
This discussion and others at the meeting will be featured in later issues of Tank Wash Monthly, in the June issue of Bulk Transporter, and on the magazine's Web site at bulktransporter.com.
