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.

Fuel Comparison

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.
