Watch Air Efficiency Rise to a New Standard.
There are many reasons why “aspiration” should be considered for product separations, and there is one essential reason that Kice Multi-Aspirators® should be the aspirator used. It is much more efficient. The Kice Multi-Aspirator® is very simple to use and yet it is extremely accurate in separating “lights” from “heavies.” Traditionally, screeners are the first idea when a separation is required for any material. Actually, an air separator – aspirator – might be better suited for the job. There are times that a screen is more effective. At other times, an aspirator is more effective. For the ultimate best results, aspirators and screens can be used together – attaining the best effects of each unit.
There are a multitude of aspirators available that will tumble and fall over a series of baffles and deflectors; but ultimately there is a single air inlet and a single air outlet. This essentially makes a one pass aspirator.
One Step Smarter
On the other hand, the Kice Multi-Aspirator® has a series of either 4 or 6 slides that allow the product to tumble back and forth while gravity flowing through the machine. At each pass, ambient air is drawn through the product, lifting the light weight particle into a selection chamber to determine if it “qualifies” to be lifted out or if it should remain with the “heavies”. Those light weight particles that have been “selected to lift” are removed from the product stream. The product then tumbles down into the next selection chamber where all remaining particles are again exposed to the selection process. Ambient air is introduced a second time, lifting the remaining light weight particles away without over aspirating any of the heavies. This process is repeated a total of four or six times – essentially removing all of the lightweight particles without removing any of the heavies. Six air inlets AND six air outlets – all in one machine.
Effective, Quiet and… Still
The Kice Multi-Aspirator® is not only effective, it is quiet, has no moving parts, no fine openings to blind or plug, can be adjusted “on the run” with an infinite number of settings, and also transports the liftings to a destination of your choice. The Kice Multi-Aspirator® has effectively been applied to about any type of product one can imagine. Any product that is typically “screened” is a good candidate for aspiration.
The Multi-Aspirator® has been applied on finished product to remove fines and dust (pellets, cereals, prills), during process to reduce dust (explosive fines, infestation, clean a product stream, etc.), and to make product improvements. The Multi-Aspirator® has been used to separate different types of plastics in “regrind/reclaim” systems, dedust fertilizer prills, clean and upgrade grain – removing damaged kernels and foreign material, separate hulls or shells from seeds or nuts, and many other applications.
We’ll Prove it to You
If you aren’t sure the Multi-Aspirator® will perform on your product, give us a chance to test it in our lab. Kice has a lab available to test most products – returning samples for your inspection. Just a few of the types of products we have operating on Kice Multi-aspirators® include grains, cereals, seeds, nuts, spices, baby foods, dehydrated vegetables/fruits, minerals, chemicals, fertilizers, plastics, wood/sawdust, pellets – virtually any free flowing commodity that you would normally consider screening. We have even aspirated gold dust, chewing gum, and candy bars. Give us a chance to show you what it will do.
This is the Flow of Air Control
For an effective separation via air classification, we control the flow rate of product into the Multi-Aspirator®, distribute the product across the full width of the unit, and then adjust the air flow to make the separation we want. For a basic system, we require a feeder (rotary stream spreader, rotary vane feeder, etc.), a source of suction (Kice centrifugal fan with air damper control), a receiver/separator (Kice cyclone collector or bag house filter), an air seal to discharge the fines (Kice rotary airlock valve), and the connecting ducting. All of these components are available from Kice, and matched to perform in concert for the maximum effectiveness.
