Continuous grain drying tower fully automatic continuous operation efficient moisture reduction suitable for various grains.

Company Profile

   Founded in 1998 and headquartered in Zhengzhou, Henan Province, China, Zhengzhou Wangu Machinery Co., Ltd. is a state-level High-Tech Enterprise integrating R&D, design, manufacturing, and sales. With over two decades of expertise in grain drying 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.

Working Principle

 Key Features & Advantages

1,Large-Scale Continuous Operation No downtime, grain in and out continuously, 100–1,000 t/day

2,Combined Concurrent-Counter-Flow Fast initial drying + deep uniform drying for both efficiency and quality
