Engineering Capability
In the organic fertilizer equipment industry, the delivery of drawings and machinery is only the beginning. What truly determines the success or failure of a production line is the ability to translate “raw material characteristics” into “equipment parameters” – starting from day one when the customer’s material is received. OFEC’s engineering capability is built precisely on this principle, offering complete end-to-end engineering from material analysis to full-line delivery.
Overview
Core Engineering Scope:
● Process Design: Customizing complete granulation process flows based on customer material characteristics (moisture content, fiber content, particle size distribution, nutrient profile)
● Equipment Design: Structural design and optimization of both individual machines (granulators, dryers, coolers, screeners, etc.) and complete production lines
● Electrical & Control Design: PLC control systems, full-line interlocking logic, and automation upgrade solutions
● Line Layout Design: 3D modeling to optimize equipment placement – maximizing plant space utilization and material flow efficiency
OFEC’s engineering team covers three core disciplines: process engineering, mechanical design, and electrical automation. Our team possesses full-process engineering capabilities spanning raw material analysis, process design, equipment selection, and complete line layout.
Process Engineering
The greatest challenge in organic fertilizer projects lies in the extreme variability of raw material characteristics – the same type of livestock manure can have completely different moisture, fiber, and NPK content depending on the farm. OFEC’s process engineering capability is built on precise understanding of material behavior.
Process Engineering Workflow:
1. Material Analysis: After receiving the customer’s raw material sample, process engineers conduct systematic testing of moisture content, bulk density, flowability, fiber content, and nutrient indicators
2. Process Scheme Design: Based on analysis results, determine granulation method (wet/dry, thermal/cold granulation), drying parameters (temperature, residence time), and equipment configuration
3. Equipment Selection & Parameter Matching: Determine specifications, power, and capacity for each stage – ensuring full-line capacity balance
4. Validation & Optimization: Laboratory testing confirms process feasibility and optimizes parameters before full-scale production
Mechanical Design
OFEC’s mechanical design team is responsible for structural design and optimization across the entire equipment spectrum – from individual units to complete production lines.
Single Machine Design:
● Drum granulator, disc granulator, and roller granulator – drum structure, drive system, and sealing system design
● Dryer and cooler – customized lifting flight design (L-shaped, spiral, etc.)
● Crusher, mixer, screener, coating machine, and packaging machine – structural design and optimization
Full-Line Integration Design:
● Spatial coordination and material flow design between equipment units
● Conveying system selection and layout (belt conveyors, bucket elevators, screw conveyors)
● Environmental equipment system integration (pulse dust collectors, spray towers, boilers, combustion units)

Electrical & Automation Design
The value of an organic fertilizer production line lies not in how advanced a single machine is, but in whether all equipment can work together seamlessly. OFEC’s electrical and automation team is responsible for:
● PLC Control System Design: Writing control logic based on process requirements – enabling sequential startup, interlocking protection, and automatic fault diagnosis
● Full-Line Interlocking Logic: Designing coordinated responses between equipment – ensuring upstream/downstream equipment automatically respond in the event of a single machine failure, preventing material accumulation and equipment damage
● HMI (Human-Machine Interface) Design: Providing operators with intuitive control panels that display real-time equipment status and process parameters
● Data Acquisition & Monitoring: Optional production data management systems – recording and analyzing line performance to support process optimization
● Remote Technical Support: Internet-enabled remote diagnostics and program upgrades for control systems
Line Layout Design
Discovering that equipment “doesn’t fit” after delivery is a common problem in organic fertilizer projects. OFEC completes line layout design through 3D modeling before procurement, ensuring:
● Precise Equipment-to-Space Matching: Confirming installation positions, access routes, and material flow paths during the modeling phase
● Optimized Material Flow Paths: Ensuring smooth material movement from feed to discharge – minimizing unnecessary conveying distance and transfer points
● Maintenance Access Space: Reserving adequate space for equipment inspection and maintenance in the layout
● Clear Civil Works Requirements: Determining foundation dimensions, anchor bolt positions, and load requirements upfront – avoiding costly rework during construction
From Design to Delivery
OFEC’s engineering capability does not end with “drawings complete” – it spans the entire project lifecycle:
1. Conceptual Design: Providing preliminary schemes and technical recommendations based on customer requirements during the initial project phase
2. Detailed Design: Finalizing process routes, equipment configurations, layout solutions, and control system architecture
3. Manufacturing: In-house fabrication at our 30,000-square-meter heavy manufacturing facility
4. Installation Supervision: Senior engineers deployed on-site to guide equipment installation and pipeline connections
5. Commissioning & Trial Operation: Completing single-machine commissioning, full-line interlocking testing, and material trial runs
6. Training & Handover: Systematic training for customer operations and maintenance teams – ensuring smooth line transfer
