engineering, the company holds more than ten provincial and
ministerial-level agricultural machinery promotion certificates.
Our products have been exported to Southeast Asia, Africa, South
America, the Middle East, and many other regions worldwide.
Product Overview
The WGH Series Continuous Grain Dryer Tower is Wangu Machinery's
flagship product line. It adopts a combined concurrent-flow and
counter-flow drying process, enabling large-volume, continuous, and
fully automated grain drying operations. Grain enters continuously
from the top of the tower, passes through the concurrent-flow
drying section, counter-flow drying section, tempering section, and
cooling section, and is discharged continuously from the bottom —
with no downtime required. This exceptional throughput makes the
WGH series ideal for large grain depots, grain & oil processing
enterprises, and large-scale agricultural cooperatives.
Equipment Application
The WGH Series Continuous Dryer Tower is designed for large-scale
continuous moisture reduction of grain after harvest. It solves the
critical post-harvest challenges of mold, heating damage, and
quality degradation in large grain depots and processing
enterprises, ensuring commercial grain meets quality standards for
safe storage and downstream processing.
