In this video, we demonstrate how the 20 tons/day mini vertical grain dryer solves post-harvest challenges for medium-scale farms and grain cooperatives. You'll see the machine's compact vertical design in action, learn about its gentle low-temperature drying process that preserves grain quality, and discover how its mobile trailer structure enables flexible field-to-storage operation without fixed infrastructure. We walk through real-world applications showing how this diesel-powered unit prevents grain spoilage during rainy harvest seasons while maintaining seed viability and commercial value.
