Not only is the DRI-Stack inexpensive compared to the conventional drying system, but within 10 days the moisture was down from 22% to 15.5%.

I am happy with the DRI-Stack system & how I can monitor & control it from my combine. I just took a load out at 15.3%.

Very happy with my system! This saved the headache of doing multiple transfers from my stirator bin. Now i can dry in my storage bin.

FREQUENTLY ASKED QUESTIONS

Still have questions? Contact us at sales@stigag.com
What bin sizes work with DRI-Stack?

DRI-Stack fits most farm bins up to 48 feet in diameter and 8 rings tall.

Taller wet grain columns (over 40 feet) can compress and block airflow, risking spoilage, so we cap 48-foot bins at 8 rings for best results.

Does DRI-Stack need its own fans?

Nope! DRI-Stack works with your bin’s existing aeration floor or drying fan to push air through the stacks. You’ll need a low-temp burner with a differential thermostat if you don’t have one, but that’s it—no added power, just better airflow.

Can I install DRI-Stack in my current bin?

Yes, it works in both new and existing bins up to 48 feet wide and 8 rings tall. It pairs with most fans and spreaders, but not with other fan controllers or moisture cables. Contact us to check your setup!

How does DRI-Stack stop stress cracks in corn?

By using low-heat drying, it gently removes moisture without fracturing kernels. This keeps corn quality high—perfect for seed or food-grade crops.

Why is DRI-Stack great for organic and white corn?

Low-temp drying keeps nutrients and quality intact, avoiding scorching. Plus, you can harvest early at higher moisture (up to 23%) to protect your yield.

Can DRI-Stack dry multiple crops?

You bet! It handles yellow corn, white corn popcorn, seed corn, soybeans, sunflowers, rye, barley, spring wheat, winter wheat, rice, and more! It’s a year-round drying and storage solution.

How does DRI-Stack boost livestock weight gain?

Better feed means better growth. High-heat drying burns off key nutrients like proteins and energy your animals need. DRI-Stack’s low-heat drying keeps those nutrients intact, improving feed quality and helping your herd gain weight faster. Plus, early harvest protects your yield, and more weight means more profit!

How does DRI-Stack’s automation save energy?

It’s like cruise control for your fans! DRI-Stack tracks weather conditions and runs fans only when needed - no more 24/7 guesswork. This cuts energy bills, dries grain faster, and prevents over-drying, so you keep more bushels and cash.

How does DRI-Stack cut labor costs?

It automates drying and monitoring, so you skip manual fan checks and reduce drive time on trips to the bin site.
