Concurrent (high-temp fast) Countercurrent (medium-temp deep) 15-20% energy saving vs single-flow

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.

Core Advantages

#	Advantage	Value to Buyer
1	Concurrent + Countercurrent	15-20% energy saving; WGH300 saves ~25t coal/season
2	24/7 Continuous Operation	No peak-season backlog; WGH500 = 500t/day = 3,500t/week
3	Up to 25% Single-Pass Drop	35% to 14% in one pass; 30% total cost reduction
4	5 Fuels in One Tower	Choose cheapest local fuel; switchable anytime
5	Indirect Heating, Food-Grade	Fume isolated; meets EU/Japan food standards
6	PLC + Mobile App	1 operator per 3-5 lines; 80% labor reduction
7	Outdoor, No Building Needed	Saves tens of thousands in building construction

WGH1000	1000	6x6	16–22	300–1380	National/port terminals

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.

Working Principle

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.

Complete System Components

System	Components	Value to Buyer
Elevating	Bucket elevator + distributor	Auto-feed + even distribution
Concurrent Zone	Hot air chamber + ducts	Fast moisture removal
Countercurrent Zone	Medium-temp chamber	Deep uniform drying
Tempering Zone	Enlarged section + insulation	Crack reduction
Cooling Zone	Cooling fan + exhaust	Cools to storage temp
Heat Source	Furnace + heat exchanger	5 fuels, indirect
Discharge + Detection	Discharge + MC meter + recycle	Auto-recycle quality
Control	Touch + PLC + sensors + app	One operator, remote

Fuel Comparison

Fuel	Calorific Value	Environmental	Suitable Region
Coal	~5500 kcal/kg	Needs dust removal	Northern China
Natural Gas	~8500 kcal/m3	Clean	Urban with pipeline
Diesel	~10200 kcal/kg	Clean (indirect)	Remote, no gas
Biomass	~3500 kcal/kg	Renewable, zero net	SE Asia, agricultural
Steam	By pressure	Cleanest	Plants with boiler

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.
