Product Overview
The Recirculating Grain Dryer is a highly efficient small-scale drying equipment developed by Wangu Machinery based on our proven continuous grain dryer technology. By recirculating grain through multiple drying cycles, this equipment effectively solves the industry challenge where small dryers fail to process high-moisture raw grain due to insufficient single-pass drying time. Equipped with an online grain moisture sensor at the discharge outlet, the dryer monitors moisture content in real time and automatically discharges grain once it reaches the target safe moisture level, achieving full intelligent automation.
Application Scenarios
1,Grain storage purchasing enterprises – rapid post-harvest moisture reduction for high-moisture grain to ensure safe storage.
2,Agricultural cooperatives large grain growers – large-scale grain drying treatment.
3,Seed companies – safe seed drying to guarantee germination rate.
4,Feed processing enterprises – moisture control of feed raw materials.
5,Grain oil processing plants – pretreatment drying of raw grain.
Working Principle
Circulating Dryer Process Flow:
Wet grain feeding → Grain equalizing buffer section → Drying section
↓
Circulating conveying system ← Grain discharge detection
↓
Grain discharge detection-Cooling section → Finished grain discharging
Key Features & Advantages
1. Circulating Uniform Drying – Grain is dried in multiple cycles for even heating, avoiding local over‑drying or under‑drying
2. High‑efficiency Heat Exchange – Multi‑layer angular box structure with high thermal efficiency
3. Intelligent Control – PLC + touch screen + online moisture detection, auto/manual dual modes, one‑key start‑stop
4. Low Breakage Rate – Six‑impeller grain discharge design, increased breakage rate <0.5%
5. Clean & Pollution‑free – Indirect heating, flue gas fully isolated from grain, safe and hygienic dried grain
6. Comprehensive Safety Protection – Three‑stage level control, over‑temperature alarm, emergency grain outlet, anti‑clogging device
Quality Assurance Certifications
1. Certified by ISO 9001 Quality Management System
2. More than ten product specifications have obtained provincial and ministerial agricultural machinery promotion appraisal certificates
3. Products comply with Chinese national standard GB/T 16714 Safety Requirements for Grain Dryers
4. 12‑month warranty for the whole machine; lifelong technical support and spare parts supply available
