About Air Knife Systems

An Air Knife is a tool used to blow off liquid or debris from products as they travel on conveyors. Air knives are normally used in manufacturing or as the first step in a recursive recycling process to separate lighter or smaller particles from other components for use in later or subsequent steps, post manufacturing parts drying and conveyor cleaning, part of component cleaning. The knife consists of a high intensity, uniform sheet of laminar airflow sometimes known as streamline flow.

An industrial air knife is a pressurized air plenum containing a series of holes or continuous slots through which pressurized air exits in a laminar flow pattern. The exit air velocity then creates an impact air velocity onto the surface of whatever object the air is directed. This impact air velocity can range from a gentle breeze to greater than Mach 0.6 (40,000 ft/min) to alter the surface of a product without mechanical contact.

Drying And Cleaning Of Bottles

Final product appearance is critical in all industries, but perhaps none more so than the beverage and food industry. Brands compete for discerning customers’ attention in an increasingly competitive market where even the smallest imperfection can be enough to sway the purchasing decision. This is especially true for the major retailers and supermarkets that expect exacting standards in product presentation. Any distortion of labels or sleeves can be the difference between securing that key customer.

Blower Assisted Air Knife System

Use Of Compressed Air Justified for Drying & Blow off

  • Most of us believe that air is free
  • True, however compressed air is not free
  • You require a lot of electrical energy, to compress the air, and store for later use
  • Due to its inherent nature, when air is compressed, lot of heat is generated
  • This heat is normally dissipated in the atmosphere
  • The dissipated heat is a lost energy
  • This energy will never be recovered and may amount to nearly 30% of input costs
