Developing a simple and sanitary solution for elevating sticky food products has always been the Holy Grail in the Material Handling Industry. Many food companies currently uses flighted conveyors, screw conveyors, bucket elevators, tote dumpers to elevate sticky and hard to release food products and these all come with a myriad of challenges. The biggest problem with flighted conveyors is how the product tends to stick to the belt and flights long after the drop points. This causes both sanitation issues and yield loss and there is no practical way to scrape the belt clean whenever flights are installed on conveyors. Screw conveyors are both unsafe and tend to degrade product quality and most food processors use them as a last resort. Bucket elevators are notoriously high in maintenance and suffer the same product release issues as flighted conveyors. Finally, tote dumpers are used in situations where conventional conveyors are simply too impractical due to the aforementioned issues. None of these methods of conveying sticky and hard to release food products really work. Processors have grudgingly lived with these shortfalls but with today’s increasing focus on food safety and food waste, this is no longer an option.
the LIFTVRAC solution
LiftVrac has developed a proprietary method to form a sanitary flat belt into a tube which envelopes the product and then elevates product to desired elevation where the belt flattens back out and allows use of both belt scraper and continous belt cleaning. There is no longer the need for flights or buckets, both which make it impossible to scrape the belt clean and make it very difficult to clean later. The tubular forming action creates gentle and equal pulling forces by increasing the overall flat moving surface area in contact with product. This gentle pull force decreases product degradation and increases overall yield. Products remain perfectly still while moving with the tube and are never compressed. As an example, potato chips run up the tube with zero breakage. Moist, sticky and delicate products all move up the tube with ease. The integrated spring loaded belt scraper finishes the job ensuring 100% of the product ends up exactly where you want it – with the customer and not on the floor. A built-in CIP that can continously wash the belt ensures the system is “food safe” at all times. The LiftVrac technology is simply amazing and must be seen to be believed. You can now move your products in a way you could have only dreamed of doing. LiftVrac is the definitive solution for elevating sticky food products such as semi-frozen fruits, granolas, soft cheeses and meat products.
