Stickpack Machines - Dairy
INV PACK have developed Ultraclean, stickpack machines capable of running at 24,000 sticks per hour, with two independent hoppers able to accommodate two different yoghurt flavours. They can pack a range of dairy products including yoghurt, soft cheese and Jelly. The stickpacks are then packed in cartons for easy storage in the freezer or refrigerator.
Laura Garcia, Marketing and Communications Manager at INV PACK explains that “The benefits of this new packaging are very clear. As an “on-the-go” format, it is an easy and fun way to drink yogurt, with no spoon needed, easy to carry and store, and it can even be eaten as an ice pop. It‘s also a guarantee for parents that children are enjoying a “healthy snack.”
The machine sterilizes flat foil through UV lamp treatment which disables microorganism DNA and achieves up to 99.9% germ reduction. A “dedusting” system based on a triple action mechanical cleaning process eliminates electrostatic charge and applies suction to remove contamination before film is fed into the sterile filling area. This area is constructed entirely of stainless steel and laminar air flow units fitted with HEPA filters and special diffusers ensure continuous production of ultra clean and practically turbulence–free air, which protects filling of these sensitive products.
Cleaning is a vital part of this stickpack system operation too. Pipe work design guarantees CIP (clean in place) fluids reach two m/s through wetted parts. Valves are positioned to ensure fast, complete product evacuation, and 100% coverage of cleaning fluid on wetted surfaces is achieved. Hygienic membrane piston valves are also used to ensure quick, consistent, easy cleaning is carried out. Finally pumps and filling nozzles are secured into the ultraclean positions during CIP, enabling a complete cleaning and sterilisation process.
INV PACK are also experts at integrating their specialized transfer system into secondary packaging systems.
