Multi-fuel Slow Circulation Grain Tower with Intelligent Moisture Control Batch Circulating Drying

Product Introduction

The Circulating Grain Drying Tower by Zhengzhou Wangu Machinery Co., Ltd. (est. 1998) is a mechanized drying solution designed for corn, rice, wheat, soybean, sorghum, rapeseed, and other grains and oilseeds. The product range includes two series: the 5HH Batch Recirculating Dryer (15-60T/batch) and the WGH/5HSQ Continuous Mixed-Flow Drying Tower (100-1500T/D), covering all scales from small farms to large grain depots.

The 5HH Series employs an alternating "drying-tempering-drying" recirculation process with adjustable hot air temperature of 45-75°C, protecting grain quality through low-temperature drying. Its compact design occupies as little as 3.4m×2.1m, with optional trailer mounting for mobile operation. The WGH/5HSQ Series adopts globally mainstream mixed-flow drying technology, combining concurrent high-temperature rapid drying with countercurrent medium-temperature deep drying in a dual-stage process, achieving 15-20% energy savings versus single-flow designs. The tower body is constructed from hot-dip galvanized steel for corrosion resistance and weather durability, supporting outdoor installation and 24/7 continuous automatic operation.

Product Applications

This equipment replaces traditional sun-drying, enabling mechanized and standardized grain drying. Primary application scenarios include:

Applicable Materials:

Product Features

1,Concurrent + Countercurrent Dual-Stage Drying:Concurrent stage: high-temp air (65-160°C) flows with high-moisture grain for rapid surface evaporation. Countercurrent stage: medium-temp air flows against low-moisture grain for deep kernel drying.

2,Alternating Dry-Temper Cycle:Tempering stage after each drying section allows internal moisture to migrate to the surface before re-entering drying, eliminating "dry outside, wet inside" and ensuring uniform whole-kernel moisture.

3,Low-Temperature Quality Preservation:5HH: 45-75°C precise temperature control, preventing rice cracking, corn fissures, and soybean hull loss. WGH/5HSQ: 65-160°C wide adjustable range, low for rice quality, high for corn efficiency.

4,Indirect Heating System:Flue gas from the furnace is completely separated from drying hot air via heat exchanger, ensuring zero grain contamination and compliance with international food safety standards.

5,Intelligent PLC Control:Touchscreen interface with real-time online moisture monitoring. Auto-discharge when target moisture reached, one-key start/stop. Supports remote monitoring and cloud data management.
