Mechanical Engineer for Paddy Dryer Design
Budget: $750 – $1,500 USD
We are a Sri Lanka–based agro-machinery company planning to manufacture paddy dryers locally.
We are looking for an experienced Mechanical Engineer with strong knowledge of paddy/grain dryers, blowers, and airflow engineering.
Scope of work:
• Design a complete paddy dryer system suitable for fabrication
• Capacity range: 5 TPH to 50 TPH (modular design preferred)
• Blower selection and sizing based on airflow (m³/hr) and static pressure
• Air ducting and plenum chamber design
• Dryer body, frame, and heater interface design
• Chimney / exhaust airflow design
Deliverables required:
• 2D fabrication drawings (AutoCAD / DWG)
• 3D model (STEP / SolidWorks or equivalent)
• Blower specification (airflow, static pressure, motor power)
• Basic airflow and pressure calculations
• Basic Bill of Materials with material thickness recommendations
This is a manufacturing-focused project. Concept-only designers are not suitable.
Applicants must have proven experience with grain dryers, paddy dryers, or industrial air systems.
