Product Overview
The WGH Series is an industrial-grade continuous grain drying tower by Wangu Machinery, designed for large grain depots, processing plants, and national reserve projects. Grain flows continuously from top to bottom, 24/7, with daily capacity of 100–1,000 tons.
Core technology: Concurrent drying zone (high-temp fast removal) + Countercurrent drying zone (medium-temp deep uniformity) + Tempering zone (crack reduction) + Cooling zone (safe storage). This "fast-then-deep" process saves 15–20% energy vs single-flow designs, with breakage increase <0.5%.
Compatible with 5 fuel types (coal / natural gas / diesel / biomass / steam), indirect heating for food-grade clean air, PLC full-auto control + mobile app remote monitoring. ISO 9001 + CE certified, exported to 50+ countries.

Note: Capacity based on corn (5–18% moisture drop); paddy capacity ~70–80% of corn. All models support 5 fuels and PLC full-auto control.
1,Wet grain is elevated to tower top. A distributor spreads grain evenly — even distribution ensures consistent drying.
2,High-temp air (up to 160C) flows downward with grain. Maximum temperature difference = maximum heat transfer. Surface moisture rapidly evaporated, MC drops from 25–35% to 15–20%.
3,Medium-temp air (90–120C) flows upward, counter to grain. Uniform temperature gradient = deep, even drying with no "dry outside, wet inside."
4,Tempering: internal moisture migrates to surface, reducing cracks (<0.5% breakage). Cooling: grain cooled to safe storage temp. Discharge: online MC check — qualified grain to storage, substandard auto-recycled.

Operating Cost Example (WGH300, 300t/day corn, 10% moisture drop, 10h/day):
- Coal: ~3t/day x $120/t = $360/day
- Biomass: ~4.5t/day x $45/t = $200/day (44% cheaper than coal)
- Natural gas: ~2,100 m3/day x $0.5/m3 = $1,050/day (most expensive but cleanest)
Conclusion: Biomass cheapest in agricultural areas; natural gas cleanest in urban areas; coal lowest cost in Northern China. One tower supports all 5 fuels — switchable anytime.
