Extruders? What are they and what are they used for?

Huh?It has come to my attention that not many people know what an extruder is and what it’s used for. Let’s hope I can address this injustice in this article!

Extruders are used to create objects of a specified length or size, this process is known as extrusion. Commonly extruded materials would be metals, polymers, ceramics, concrete and even food.

At Quadro Alloys Trading Enterprise we specialize in the design, manufacture and maintenance of extruder units/machines used in food extrusion; the process whereby a specific set of ingredients are mixed together and forced through a large, rotating screw which is tightly fitted inside a stationary barrel and then through a perforated plate or die, the resultant mix is known as the extrudate.

The end product can be anything from fish pellets to dog food.

I mentioned earlier that not knowing all of this was an injustice, well, here’s what I mean: In Africa (and some other countries) poverty is an issue that affects health conditions; some are struggling with malnutrition and some even die from it. Our extruders (in conjunction with our hammer mill machine) can be used to help solve this problem; the soya bean, a legume native to East Asia, is an amazing source of cheap protein used for things like oil, meal, flour, infant formula, dietary (meat and dairy) extenders or substitutes and cattle feed. In addition to these, floating fish feed (something we specialize in and are especially proud of) is often used in feeding the “water chicken”, a species of fish called the Tilapia (which is easily farmed). This fish has now become an accepted mechanism used for the feeding of the poor which is probably one of the easiest ways to feed them – and our philosophy is “feed the fish, feed the poor”.

Extruder machines are miracle inventions, and with your help as an entrepreneur, we can work together and make a difference in this world.


The Basic Full Fat Soya Extrusion Process

Every manufacturer of extruders and feed plants have their own method to the final Full Fat Soya product, this is a basic overview of our production process.

ExtrudersThe product is fed from the Silo into the Soya Bean Cleaner and is then fed to the Hammer Mill(available in  7.5kw, 22 KW,30kw,37kw,55kw,75kw) with the suitable screen size(available in 0.75mm, 0.9mm, 1.2mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 5mm, 8mm & 10mm). Our finest screen 0.75mm is able to produce a product of under 200 micron.).
From the Hammer Mill it is blown using the 7.5kw External Drive Blower to the Cyclone.  The product is then rotary fed into the Open Trough Auger ontop of Volumetric Feeders which are feeding the extruders via a Variable Speed Drive.
The product is then extruded at 160 degrees and taken via the Open Trough augers into an Incline auger with canopy and blower which blows off the initial steam generated during the extrusion process. The product is then fed into cooling Bins via an open trough auger with gate slides. The finished product can then be bagged-off after cooling from the Bagging-off unit or can feed directly into a bucket elevator into silos for storage.
