T&T worked for many years on remanufacturing and upgrading all kinds of spiral conveyor technology, produced by various North American and European manufacturers. This hands-on knowledge led us to designing and manufacturing our own spiral conveyor technology. We did not intend to reinvent the spiral cooling conveyor, just to build and improve upon the old design with a better, more reliable, low maintenance and longer lasting drive system.
We redesigned and eliminated the typical main cage drive with the very large size cumbersome drive chain and tooth segments by going to a main cage with gear drive, incorporating a thrust bearing. In 2014 T&T applied for a US Design Improved Patent and the patent for the improved design was received in 2015. This spiral cooling conveyor design was also successful in becoming a sanitary solution. In 2015 T&T received the Eco Design and Sustainable Technology award from the American Society of Baking (ASB) for its design improvement.
