Air Knives are easy and also very efficient devices for drying and also cleansing products. An Air Knife System utilizes a high strength, consistent sheet of air which is used to efficiently:
– Eliminate liquids
– Control the thickness of fluids
– Dry fluid finishing’s
– Eliminate international fragments
– Great item surface areas
– Develop a hold back force to help in the mechanical bonding of materials to the surface
Air Knives are typically the most effective and also effective technique of getting rid of or managing international substances for any surface. A Lot Of Air Knives are fixed with items travelling through them on a conveyor nevertheless there are also systems where the product is stationery and also the Air Knives walk around it. The potential that air knife system offers various sorts of markets is therefore substantial.
Air Knives Technical Information
A commercial air knife is a pressurized air plenum with a constant port whereby pressurized air leaves in a laminar uniform circulation pattern. The departure air velocity creates an effect air speed into the surface area of whatever product the air is directed to. This impact air rate could range from a gentle wind to greater than Mach 0.6 = 454 mph = 731 kHz = 40,000 fpm = 203 m/sec. Therefore an air knife modifies the surface of an item without mechanical call.
Air knives on an assembly line generally range from 100 to 3048 mm 4 to 120 inches in length with a discharge air slot ranging from 0.40 to 2.0 mm 0.015 to 0.08 inches. A stationary air knife arrangement could call for from one to ten or more air knives depending on the application requirements. Air is blown up via the air knife slots using a high speed centrifugal blower to deliver the established departure air volume and rate required. Electrical currents from anti-static bars can likewise be injected into the departure air knife stream to counteract the fixed electrical energy charge on some surface areas.
