What Is a Grain Dryer?
Grain dryer machine is a mobile grain crop drying equipment for farmers. It controls heat and airflow to reduce the moisture content of harvested grains (such as corn, wheat, rice and soybeans) from about 17-30% to a safe storage level (8-15%). The grain after drying is evenly heated and hydrated, with good quality and no discoloration or deterioration. Proper drying can prevent mold growth and quality degradation during storage. Farm dryers like the mobile vertical grain dryer for small farms allow growers to start harvesting early when the moisture content is high and dry the grain immediately, thereby minimizing weather risks and losses. Generally suitable for: farms, grain stations, and grain growers.
How Does A Grain Dryer Work
The mobile dryer uses a mixed flow drying process to dry grains with hot air. Its interior consists of multiple layers of staggered angular ventilation boxes, and the outside of each ventilation box is filled with grain to be dried.
Grain enters from the top and flows from top to bottom along the gaps in the ventilation boxes; hot air enters from the air intake ventilation box, passes through the grain layer and is discharged from the exhaust ventilation box. The hot air flows alternately in the same direction and in the opposite direction of the grain flow, which is called mixed flow. When the hot air passes through the grain layer, it transfers heat to the grain grains, causing the grain grains to heat up, and the water evaporates into the air and is discharged as exhaust gas.
The dried hot grain continues to move downward into the slow recovery section, where the temperature and moisture inside the grain grains and the surface layer are balanced to achieve uniform dehydration. Subsequently, the grain enters the cooling section, where it is cooled to a temperature suitable for storage by the cold air, and is finally automatically discharged by the grain discharge section.
Grain Dryer Advantages
On‑Farm Efficiency
Eliminates transport of high‑moisture grain to remote dryers, reducing handling time and costs
Energy Savings
Mixed‑flow configuration yields up to 20 % lower fuel consumption versus cross‑flow designs due to improved heat recovery
Rapid Throughput
Typical capacity of 10–25 t/h meets small to medium farm demand, allowing same‑day drying after harvest
Uniform Grain Quality
Counter‑current sections ensure kernels see progressively cooler air, preserving seed viability and end‑product quality
Grain Drying Machine Features
Vertical Mixed‑Flow Design
Grain and air flow both co‑ and counter‑currently for efficient heat/mass transfer in a compact footprint
Portable, Trailer‑Mounted Unit
Mounted on wheels with a tow hitch, enabling on‑farm mobility between fields and bins
