A short five months later, Krispy Kreme wanted to upgrade to auto- matic feeding to handle its increas- ing volume. Adding the new KR-U feeding system proved to be the right decision. The feeding sys- tem combines a staging conveyor, vacuum feeder, and transfer belts sufficiently powerful enough to handle valve and gusset type multi-wall Kraft bags, die cuts, and rsc cases. This equipment was designed for easy integration with the Optimizer HF printer that Krispy Kreme was already using, allowing Krispy Kreme to become the first installation for Iconotech's Optimizer KR-U. The KR-U provides a nearly continuous in-feed process to the printer from a single side- entry point. A single operator can place 10-in. tall stacks of about 60 valve bags on the 10-ft staging conveyor. Media is then indexed over to the loading lift table. The lift table rises to the pick-off po- sition where the vacuum feeder picks off bags one at a time from the top and moves each to the transfer table for delivery to the printer bed. Feed dogs inside the printer bed drive the bag through the nip point where it is con- tacted between the print cylinder and impression roller creating print up to 50 pieces per minute. The printer accepts bags from 12 x 18 to 36 x 36 in. long. When empty, it drops down to receive the next stack. Total re- load cycle is 5 seconds. The 10-ft conveyor holds three stacks of bags, one in the lift table and two waiting. As Krispy Kreme expects its production to increase and looks to attain maximum throughput, the addition of a restacker and return conveyor would complete the system. This would allow for printed bags to be recaptured in a restacker in bundles of 25 bags af- ter exiting the printer. They would be brought back around to the op- erator on a return conveyor for ad- ditional printing on the other side of the bag or re-palletizing. With the implementation of the Optimizer KR-U, Krispy Kreme has met customer expectations on print quality, eliminated the prod- uct rejections suffered by the in- ternational sales department, and met increased production with plenty of capacity still available.

Bags flow between the print cylinder (on top) and impression roller for exact placement of print at 50 bags per min- ute throughput. Vs. Vacuum Dryer Usual advantages: • continuous atmospheric pressure operation • unattended operation • can dry to lower final moistures (as low as .001%) • no personnel exposure to product • no dust to surroundings (or to plug filters) • closer temperature control • compact scale-up Actual comments from users where the TURBO-DRYER ® replaced a vacuum dryer: — "You'd have to break the operator's arm to get it away from him." — "It's the best piece of equipment in our plant." — "We turn it on and forget it." — "Why didn't we buy this last time?"
