If you operate a grain depot, processing plant, or agricultural cooperative, every harvest season brings one core challenge:
Mountains of wet grain pile up. Without drying within days, grain heats, molds, and downgrades — tens or hundreds of tons can turn from premium to waste overnight.
Batch dryers handle only a few to tens of tons per cycle: load → dry → unload → reload, repeating endlessly with obvious throughput bottlenecks.
The continuous drying tower solves exactly this: wet grain enters the top continuously, dried grain exits the bottom continuously, 24-hour non-stop operation, 100-1000 tons per day.
This is not "a bigger dryer" — it is a fundamentally different working mode, like assembly-line production replacing one-by-one handcrafting.
The WGH series is an industrial-grade continuous drying system developed by Wangu Machinery for large grain depots, processing enterprises, and national grain reserve projects.
It employs concurrent-countercurrent combined drying: grain enters from the top, passes through concurrent drying (high-temp rapid moisture removal) → countercurrent drying (medium-temp deep drying) → tempering section (moisture equalization, crack reduction) → cooling section → continuous discharge, all without interruption.

Product Features
1,Grain flows in and out continuously with no batch waiting. 100-1000 t/d capacity, thousands of tons per season — the throughput guarantee for large-scale operations.
2,Concurrent section removes surface moisture fast; countercurrent section dries deeply. The combination saves 15-20% energy versus single-flow drying with better quality.
3,High-moisture grain can be dried to safe levels in a single pass — no repeated cycling needed. Saves time, fuel, and labor, reducing total cost by over 30%.
4,Strict grain temperature control with tempering process. Crack rate <0.5%. Every 10,000 tons of paddy yields ~50 extra tons of whole rice — direct economic gain.
5,Flue gas is completely isolated from grain. All-steel tube heat exchanger ensures clean, odorless hot air. Dried grain meets food-grade standards — suitable for processing and seed grain.
6,Supports coal, oil, natural gas, biomass (straw/rice husk), and steam. Switch fuels based on local energy prices. Firewood in Africa, rice husk in Southeast Asia — use what is cheapest locally.
7,Touchscreen operation, auto-monitors moisture, temperature, and grain level. Remote monitoring and mobile APP supported. One operator manages multiple lines — 80%+ labor cost reduction.
8,Heat consumption 5000-7000 kJ/kgH₂O with baghouse dust collection. Compliant with national emission standards — no environmental penalties, potential subsidies in some regions.
