The demand for increased production rates combined with more stringent quality objectives has resulted in a desire to reduce production costs and bring products to market quicker. One factor to be dealt with is the phase out of solvent based inks for labeling food items, bottles and packaging. Label adhesion, inkjet encoding, inspection, testing and packaging systems are all adversely affected by moisture left on the product surface.
Manufacturing plants with several processing lines can significantly improve the drying process and decrease compressed air usage and the associated utility costs by incorporating Sonic Air Knife Drying Systems. While some applications may be satisfied by “blow-off” from compressed air nozzles, they are not a cost effective choice for large coverage areas or when a high degree of dryness (90%-100%) is required. Sonics air knives often result in an energy savings of 50+%. The corresponding R.O.I. usually falls to within 6 months…just on energy savings alone!
With food processors and packagers demanding that production lines run faster, occupy less space, be cleaner, have more flexibility and operate more efficiently than ever before. Sonic Engineered Blower and Air Knife Solutions, with their guaranteed performance, take a huge burden off the clients shoulders. Some examples are conveyor lines requiring surface water/moisture to be completey removed, coatings requiring precise thickness control, solids or debris that must be displaced or static eliminated. Sonic has set the standards for all. Sanitary air knives and HEPA filtration are also available options to handle the most stringent requirements.
Some time ago a meat packaging company contacted Sonic Air Systems with a challenging drying applicaiton. They needed a way to dry packaged meat products prior to shipment. Removing water from the package surface was relatively easy, but the key challenge was the package sizes. Each cut of meat was a different shape and length – how can the efficiency of an air knife drying system be maximized? Rather than install the knife at a height that would allow the largest package to pass-by (inefficient for smaller packages) or requiring continual adjustment based upon the packages being processed (time consuming), this air knife system automatically maintains the optimal air knife height no matter what the package shape is. This enables the use of minimal horsepower and ensures a dry product. The self-adjusting air knife system can be applied to any application where target size varies.
Picture two droplets, equals in size. Now, imagine atomizing one into a thousand smaller droplets while leaving the other untouched. Measuring the surface area of each “small droplet” and summing them up yields a total surface area surpassing that of the single large droplet. In essence, smaller droplets equate to increased surface area at a given flow rate – a canvas for more efficient heat transfer, heightened surface contact, or heightened reactions within a gas stream.
