COMPARISON OF BLOWER ASSISTED AIR KNIFE SYSTEM
WITH OTHER SYSTEMS

With high speed automated production lines, washing, cleaning, cooling, quenching, rinsing with liquid and many such in line processes have become essential. Most of these processes will leave liquid (mainly water based solutions) on to product.

In most cases this residual liquid needs to be dried, or removed from the product, to facilitate ink jet coding, printing, packing, cooling etc.

There are many different methods to help drying/removing liquid from product. Most popular being :

• Mechanical wiping with squeeze rolls or sponge or cloth.
• Blower assisted Air Knife System.
• Compressed air assisted Air Knife System.
• Thermal Drying.

In most cases drying with Mechanical Wipe, do not yield complete and effective drying.

Other three processes in most cases, can give desired results, with varying degree of performance and costs.

Hence, attempt is being made to compare other three systems, its advantages and disadvantages, capital cost and energy cost comparison and other considerations.

Some factors in comparison are indicative only, and data may change for different parameters of applications.

Reader may use this comparison as guidelines and draw their own conclusions to decide the system best suited for their application.
