Frequent Questions

The GCS grain cleaners typically come with 3 chutes plus a heavy stream and the fines blowing out the end. Depending on setup and the grain being cleaned you can group multiple streams together.

For example, if you are just blowing out light trash you might use 2-3 augers: 1 to fill the hopper, 1 or 2 for the grain (bests/seconds), and leave the rock and dust to blow on the ground.

Generally we find the air cleaner easier to operate and more flexible. A screen cleaner requires having multiple sets of screens to change from one product to another whereas the air cleaner fan speed is easily adjusted. The air cleaner also works on density so can remove insect and frost damaged seeds.

A rotary screen cleaner like the Farm King 480 is good if you are only cleaning 1 product that is easily separated by size, eg splits out of chickpeas.

Cleaning for seed we recommend the air powered cleaners, in particular the 5t and 10t models are popular for sowing.

GCS cleaners are very efficient and reach their capacity using single-phase power. Most models work on a 10A circuit and the largest 60t uses a 15A plug.

A 7.5 kVA generator is plenty to run a grain cleaner and a few pencil augers.

The scalper works as a pre-cleaner to get rid of any large sticks and debris that might not flow or get jammed up in the air cleaner inlet gate.

If you are just looking to remove large matter a scalper may be all that is needed. Contact us to discuss your options.

Every customer has a different setup and requirements but some ways they have been mounted are:

  • A trailer with generator and pencil augers

  • Frame that can be forked onto a ute and moved around to silos/trucks

  • Fixed location and trucks brought to it

We recommend a 20L sample of your product to trial but some cases where the GCS cleaner struggles are:

  • Product does not flow smoothly or bridges in feed hopper (wet or damp, large objects like sticks and leaves)

  • Where the target and undesired products have a close weight/size ratio (eg in grape mash, dried skins and seeds)

In these situations a scalper cleaner is ideal for either a first-pass or complete clean.
