Sorghum Cleaning

Cleaning stramonium from sorghum, sample done at Farmfest 2018 in Toowoomba. Customer brought a sample with a high rate of stramonium as well as star burr and screenings to test the machine out. This result was from only a couple of minutes of setting up.

First Chute	3 stramonium seeds in 5L of sorghum.
Second Chute	High rate of splits and shells, insect damaged seeds, some full chickpeas
Third Chute	High level of stramonium, star burr
Fines	Dust, straw, shells

Chickpea Cleaning

Starting sample had high level of splits off harvester and some insect damage. The GCS Cleaner can struggle removing splits as the density is very close to a full chickpea but in this case it worked very well.

First Chute	Low rate of splits
Second Chute	High rate of splits and shells, insect damaged seeds, some full chickpeas
Third Chute	Splits & shells
Fines	Splits, small seeds (canola) and shells

Rice Cleaning

Cleaned Packaged Rice with Weevil contamination in a GCS-200 5t/hr machine.

Lupins Cleaning

Just a quick demo for a customer who brought a sample in. Did not play with the settings at all and got a result they were happy with. With a few minutes of adjustment we would get a better recovery from the second chute.

Cleaning Peanuts

At CRT Farmfest 2018 in Toowoomba a farmer brought by some peanuts to trial in the GCS Cleaner. Unfortunately the opening on the 5t display model we had there was too small to reliably feed the peanuts without bridging so we brought back a sample to test in a 10t machine.

The 10t grain cleaner worked a treat for feeding the peanuts with its much larger opening. Because of the larger machine we needed a larger sample size and that caused an issue with the primary chute overflowing the bucket, causing some full peanuts to carry over to the third chute.

This test was done as a once-off at 40 with no fine tuning.

First Chute	Clumps of dirt, a few peanuts that may have fallen in when the second chute filled up.
Second Chute	Majority of peanuts, all shells had at least one peanut.
Third Chute	High number of good peanuts likely from overflow of second chute. Higher rates of single nuts.
Fines	Empty shells, sticks, vegetation

Clover Seed Cleaning

Hemp Cleaning

The GCS Cleaner easily separates out leaves, chaff, shells, and weeds from hemp seed. Deadly Nightshade did not separate fully.
Passing dirty product through a scalper as a pre-clean gives a perfect mulch byproduct with no viable seeds.

Frequent Questions

How many augers are required?

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.

Should I get a screen grain cleaner or air grain cleaner?

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.

Electrical requirements

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.

Do I need a Scalper?

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.

Mounting and Setup

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

Where does the GCS Grain Cleaner struggle?

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.

“Saved us a lot of money already…”
“We purchased the 60t/hr GCS Grain Cleaner to grade mice droppings out of the sorghum. We were getting loads rejected so we made a quick decision to grab the last grain cleaner available at Beulah Machinery at the time.
“It has been awesome. We haven’t had any loads rejected since and it’s as simple as to use. We were amazed at how much rubbish it removes.
“It’s saved us a lot of money already. We would have had to pay up to $28/t to get it graded. Overall, we will probably grade up to 1000t this season so it’s around a $28,000 saving straight up.
“We’ve also recently put it to work grading dirt out of the wheat. We plan to use it for the wheat, barley, chickpeas and grass seeds into the future. Ideally, we’d like to set it up so we grade everything we put into storage.
“Originally, we were looking at a smaller cleaner, but we are glad we got the larger one in the end. It just gives us a lot more capacity.”

— Wayne M, Dalby QLD

“Paid for itself already…”
“We purchased the cleaner to clean our own oat seed. We only had a small lot to do, and we couldn’t get anyone to come and do it at the time. Around January/February when we need it done, the contractors are all out west doing the big jobs and it’s always a problem getting anyone.
“Our choice was to buy in new seed or get a cleaner and do it ourselves. As far as I’m concerned, the cleaner has paid for itself already. If we’d bought more seed and our own was still sitting in the shed, the mice would have eaten it all anyway.
“The GCS Cleaner is simple and works well. It looks like we have 100 percent germination in the oats now - so it’s done a good job!”

— Gavin M, Tamworth NSW

“Unbelievably happy with the seed we’ve done…”
“We’ve always tried to clean our own seed. We bought the 20t/h GCS Grain Cleaner to compliment another cleaner without a fan. We cleaned the wheat, barley, and lentil seed. It did an excellent job especially getting all the light stuff out.
“You try to keep your seed as clean as you can. We’ve been unbelievably happy with the seed we’ve done. It’s better than some of the new bagged seed you get. With how we have it all set up, I don’t think we could find anything we can’t clean. We’ve already had a few neighbours coming over to check out our system.”

— Andy C, Rainbow VIC

“Having the cleaner is ideal…”
“Be bought the 10t/hr GCS Grain Cleaner in early 2021 to clean our own grain for sowing and generally value add to the grain when you need to. We store our grain in three sheds and we sell what we don’t use ourselves.
“Having the cleaner is ideal. When we need more for sowing, we just go and grab some. We often have a terrible time with blockages when we’re sowing, but we’ve had none since using the new cleaner.”

— Keith J, Trundle NSW

“A good option to be more self-sufficient…”
“I purchased a 5t/hr GCS Grain Cleaner at the end of 2020. The price of cleaning and the price of seed the last few years has been out of control. It’s also hard to get anyone to come and clean. I’ve been really happy with how it’s gone. It’s simple to use and it did a really good job on the grazing wheat. It’s a good option to be more self-sufficient."

— Doug C, Berridale NSW

“It’s actually paying itself off…”
“I got let down a few times with graders so decided things would need to be changed. This is our second year with the GCS Grain Cleaner. I would say it’s actually paying itself off.
“It’s simple to use and has done a good job on small seeds right through to the lupins. We’ve also seen a great result with the lucerne seed – bigger, heavier seeds in the sample and it looks healthy when it comes up. It was also excellent for reducing the black oat seed in the wheat last year.”

— Ben E, Wagga Wagga NSW

“Convenient…we can do it ourselves in the down time…”
“We purchased the GCS Grain Cleaner originally to grade the faba beans. We’d used our neighbours one the year before and it worked quite well so we decided to get ourselves one.
“The mobile grader wasn’t particularly good on the beans. The less you auger them around, the better the germination so we just grade them straight out of the silo.
“It does just as good a job as the mobile contractors, but it’s more convenient because we can do it ourselves in the down time. You don’t have to do much really. You just have to be there.
“We also did all the wheat and barley seed with it. It takes a bit of time, but it’s worth it. We wanted to grade the pods out of the vetch and that worked well too. It all went through the airseeder well without any problems.”

— Brian C, Junee Reefs NSW

“Saved us a lot of worry…”
“We purchased the GCS Grain Cleaner late in 2020. We couldn’t get wheat graders when we wanted them so having our own cleaner saved us a lot of worry. It was great knowing you can do the job yourself when you need it done and if we needed a bit more seed we could just go and grade it without any hassles.”

— Rodger W, Molong NSW

“It did an excellent job…”
“We bought the scalper to tidy up the sample in our grading shed. It’s been good to get out any of the big particles like the stalks or rocks. We’ve also graded some mice droppings out of canola, and it did an excellent job of that too.”

— Luke M, Erskine Park NSW

“Saved us a heap of time…”
“We knew we were going to have to grade the oat seed this year. It had 3inch straw through it and it was going to make sowing difficult. Finding people to do the grading is hard out here so we decided to get our own cleaner.
“We ended up putting both the oats and barley though the grader and it did a really good job. We didn’t have any block ups on the sowing rig. It was plenty good enough to go through and saved us a heap of time.
“The 5t/hr cleaner was more than good enough to get the job done. Down the track we might look to upgrading to the 10t/hr model.”

— Jack H, Parkes NSW
