Outdoor Batch Dryer System for Bright Food Premium Rice Base
Key Highlights
Haifeng Rice (a key subsidiary of Bright Food Group), operating a major green food and grain reserve base in East China with an 1,800 t/d drying capacity, urgently required a civil-cost-saving, highly uniform, and intelligent outdoor grain drying system for processing paddy and wheat.
Deployed a complete GSS outdoor batch circulation grain drying system specifically engineered for paddy and wheat. The equipment package includes 12 units of GSS Outdoor Batch Dryers, equipped with dual-burner heating systems, cross-flow thin-layer drying technology, cyclone dust extraction systems, online Moisture Monitoring & Control System, and a central integrated smart control platform.
Outdoor modular design eliminated civil building approval and reduced construction cycles and costs; dual-burner low-temperature drying protected grain quality and vitality; central smart control and zero-residue bottom augers ensured high efficiency and prevented variety cross-contamination.
Client Profile: A Premier Green Grain Reserve Base in East China
Located in the Yangtze River Delta, Haifeng Rice (a key subsidiary of Bright Food Group) operates the largest municipal green food and grain reserve base serving Shanghai. The complex features a 330,000-ton storage capacity, an 1,800 t/d drying capacity, and a 100,000 t/a rice milling output, serving as a strategic hub for regional food security.
Goals & Challenges: Civil Cost Optimization & Uniform Low-Temperature Drying
As a premier green food base, the facility faced several universal industry challenges during grain post-harvest drying and handling:
- High Civil Construction Costs & Tight Timelines: Traditional drying plants demand heavy civil foundations and lengthy building approvals. The client required a modular, outdoor-ready system that bypasses civil permits and accelerates project commissioning.
- Strict Quality Protection for Paddy & Wheat: Excessive heat degrades germination rates, seed vitality, and head rice yield. The solution required gentle low-temperature cross-flow drying integrated with real-time moisture tracking.
- Multi-Variety Flexibility & Zero-Contamination Operation: Processing multiple grain varieties demands rapid, zero-residue bottom cleanout to prevent cross-mixing, alongside integrated dust suppression for clean production.
Customized Solution: Outdoor Batch Dryer & Smart Control Package
To satisfy Bright Food Group’s rigorous operational and quality standards, GSS delivered a customized outdoor grain drying and bulk handling solution specifically engineered for processing paddy and wheat:
- GSS Outdoor Batch Dryers (12 units) : Deployed 12 units of GSS Outdoor Batch Dryers (1,800 t/d total capacity). Featuring heavy-gauge galvanized protective panels and a modular “building-block” architecture, these outdoor units bypassed civil building permits, reduced infrastructure CAPEX, and slashed erection timelines.
- Dual-Burner Thermal System & Multi-Fuel Flexibility: Each unit integrates 2 precision burners capable of switching between diesel, natural gas, steam, and agricultural biomass to optimize regional energy OPEX. Paired with thin-layer cross-flow physics and online moisture sensors, it delivers gentle, highly uniform drying.
- Central Smart Control & Bridge-Free Top Conveying: Powered by a central PLC supervisory platform for remote monitoring, auto-logging, and predictive fault diagnostics. Top conveyors mount directly onto dryer crowns, eliminating costly overhead steel trestles. Bottom augers incorporate multi-port cleanout gates for zero-residue operation.
- Cleaner & Cyclone Dust Extraction System: Integrated pre-cleaning units to remove impurities before drying, paired with high-efficiency cyclone dust extraction systems to collect dust centrally and maintain a clean, safe working environment.
Project Value: Capital Efficiency, Premium Grain Preservation, and Smart Operations
Capital Efficiency & Faster ROI
The outdoor modular framework bypassed civil approval delays and eliminated overhead steel trestles, drastically cutting initial CAPEX and accelerating time-to-market.
Grain Quality & Milling Yield Preservation
Gentle low-temperature cross-flow drying eliminates thermal stress and kernel cracking, boosting head rice yield and preserving germination vitality.
Smart Control & Zero-Residue Cleaning Enhancing Operational Efficiency
Remote monitoring, fault pre-warning, and multi-port cleanout augers streamlined operation, eliminated cross-variety contamination, and lowered labor and maintenance expenses.
As a primary green food and staple grain reserve base serving Shanghai, maintaining high grain quality while managing capital costs is paramount. The complete outdoor grain drying solution provided by GSS has delivered exceptional results. The 12 Outdoor Batch Dryers eliminated the need for complex civil building approvals, saving both construction time and costs. Their dual-burner temperature control and cross-flow drying keep paddy and wheat quality intact, while the central smart control system simplifies daily operations. GSS has provided solid equipment backing for our modern, high-standard grain hub.
