Our customer’s reviews

Zach Bender

Wisconsin, USA

We purchased an ADS-400-CDC grain cleaner with the SGC-400 pre cleaner this year and couldn’t be happier with it. We replaced an old machine that was worn out and had lots of moving parts. The ADS-400-CDC doubled and even tripled our seed cleaning capacity. It is easy to operate and does a fantastic job.

I run Organic Production Services. We had been using ADS 2000 CDC running 100 tons per day through it for 4 months. Now we are going up to ADS 6000 CDC. Runs good, no problems, very satisfied. We are an organic soybean crushing facility in NC.

Kyle Schminke

Iowa, USA

Wow what a product! I was just going to rent the machine for a week but after using it for just a few bushel I know that it was well worth the money. Probably one of the simplest machines I’ve ever had. Great product, Anna was awesome to work with.

Harry Simmons

North Dakota, USA

I’m very happy with the finished product that we were able to achieve with the separator, and in fact would like to just make the purchase. We finished everything we have right now, but will have 3-4 times more next year.
