The Low-Cost, High-Efficiency Solution That Turns Mixed Grain into Premium-Quality Produce
For generations, small and medium-sized farmers have faced the same grueling ritual when harvest season arrives. After spending months nurturing their crops, they find themselves squatting in sun-scorched fields for days on end, manually winnowing grain—lifting and tossing heavy loads of wheat, rice, or corn, bending down repeatedly to pick out shriveled kernels and straw debris. They work from dawn to dusk, yet after all that back-breaking labor, they might still end up with barely a few hundred pounds of truly clean grain.
The physical toll is immense. The time lost is heartbreaking. And worst of all? The premium market prices for high-quality grain slip away because the cleaning process simply can’t keep up.
The grain cleaning challenge is a well-documented pain point for small-scale farmers globally. Traditional winnowing methods are not only labor-intensive but also unreliable, often requiring farmers to wait for the right wind conditions—a problem that leads to crop spoilage during monsoon seasons or untimely rains . Studies have shown that smallholder farmers face significant post-harvest losses due to inadequate processing equipment, resulting in poor grain quality and economic losses .
But what if there was a better way?
Introducing the EX-50 Agricultural Grain Air Sorter from Tongying Machinery
A low-cost, high-efficiency cleaning tool designed specifically for ordinary farmers and small-scale grain processing points.
The EX-50 is engineered to solve exactly the problems that have plagued small-scale grain producers for decades. With its hand-cranked and electric dual-drive system, this machine is built for real-world farming conditions where power outages are a constant worry. One machine, two power sources—your work never stops.
Why the EX-50 Changes Everything
✅ Pure Physical Green Sorting – No Chemicals, No Water
The EX-50 relies entirely on airflow power to separate grain from impurities. The process is 100% physical—no chemical agents, no water consumption, zero secondary pollution. The grain you produce is clean, safe, and meets the highest standards for green agricultural processing.
✅ Dual-Mode Power – Work Through Any Power Outage
When electricity is available, the 180W motor runs continuously with stable heat dissipation. When the power goes out—a common occurrence in rural areas—simply switch to the hand-cranked mode. No downtime. No excuses. Just uninterrupted productivity.
✅ One Machine, Multiple Grains
The EX-50 is compatible with wheat, rice, corn, and various miscellaneous grains. This isn’t a one-trick pony—it’s a versatile tool that adapts to your diverse agricultural needs.
✅ Stepless Air Volume Adjustment
Different grains have different weights and sizes. With the EX-50, you can manually adjust airflow speed to match each material perfectly:
- For light impurities: Increase air pressure to blow away chaff, dust, and crushed particles.
- For full, heavy grains: Decrease air pressure to retain every quality kernel.
This adaptability ensures optimal cleaning results for materials with different moisture contents and categories.

How the EX-50 Compares to Traditional Methods
The contrast between traditional grain cleaning and using the EX-50 couldn’t be starker:
| Aspect | Traditional Manual Winnowing | EX-50 Grain Air Sorter |
|---|---|---|
| Labor Required | 5-6 people working full days | 1 person operating easily |
| Efficiency | Hundreds of pounds per day | 800 lbs per hour |
| Reliability | Wind-dependent; weather ruins crops | Works anytime, anywhere |
| Cleaning Purity | Inconsistent | ≥ 96% |
| Physical Strain | Back-breaking, exhausting | Minimal effort required |
| Power Dependency | None (but wind-dependent) | Electric or hand-cranked |
| Cost | High labor costs, time lost | Extremely low operating cost |
As one study documented, farmers using manual winnowing often have to stand for hours waiting for a gust of wind, balancing themselves on bamboo platforms while the quality of their rice deteriorated . The EX-50 eliminates all of this.
