Bosch Packaging Technology Pack 403 fully automated horizontal flow wrapper

Company: Bosch Packaging Technology

Equipment Snapshot: Bosch Packaging Technology has developed a new version of its fully automated horizontal flow wrapper Pack 403, which is specifically designed for harsh environment use. The machine will be presented at this year’s Pack Expo 2019 in Las Vegas, along with a Paloma pick-and-place robot, which is also designed for harsh environment use. The Pack 403HE comes with all the proven features of the Pack 403 and is suited for medium to high-speed wrapping. The machine is able to wrap a wide variety of products ranging from biscuits, chocolate, cookies and crackers to frozen foods or meats. “We have designed the new Pack 403HE to meet the growing need of customers with strict hygienic requirements. To avoid contamination with allergens, germs or unwanted ingredients, food manufacturers need machines that are easy to clean,” says Kelly Meer, product manager at Bosch Packaging Technology in New Richmond, WI.

Today, food manufacturers often produce different products on the same machine. “Keeping the products free from unwanted substances such as traces of peanuts or wheat can be a challenge in terms of cleaning. The Pack 403HE provides improved features to facilitate particularly intensive cleaning,” Kelly Meer explains. It differs from the standard version in terms of product design and material. Customers can apply aggressive cleaning agents including alcohols or acids, and easily wipe them off with water after they have taken effect. Water and cleaning agents will simply run down the drain.

“We call this the foam-and-rinse concept. In contrast to high-pressure cleaning with air or water, customers avoid the risk of spraying substances or germs. The foam-and-rinse method guarantees an easy and reliable washdown. The concept will soon also apply to the Paloma pick-and-place robot,” Kelly Meer says.

The Pack 403HE also features washdown motors and gearboxes meeting the BISSC standard, sanitary feet, and a continuously-welded stainless steel main frame plate. Stainless steel guarding, robust plastics, removable parts, sloped surfaces, and easy-to-clean gaps between machine components further simplify the cleaning process. The machine’s cable connection to its electrical cabinet has been sealed to prevent the penetration of moisture or unwanted substances. Clear tubes help to detect any contamination. The wrapper is also equipped with a washdown infeed and stainless steel etched and stand-off labels to also support convenient cleaning.

The Pack 403HE produces up to 400 packages per minute, reaching a maximum film speed of 76 meters and includes all of the same features offered in the Pack 403. The automatic film splicer allows for fast film changes without interrupting production. The machine is equipped with servo-driven power feed rollers to optimize film tension and tracking. It also has cantilevered and removable discharge belts that reject faulty packages with compressed air.
