Grain Processing Plants

Ideal for flour mills, corn processing plants, and multi-grain processing facilities requiring consistent, high-volume drying as part of their processing lines.

Large Agricultural Cooperatives

Suitable for large agricultural cooperatives that collect and process grain from multiple member farms, requiring 500 TPD capacity to handle collective harvest volumes.

Commercial Grain Storage Facilities

Grain storage and terminal operations that receive wet grain and need to dry it to safe storage moisture levels before medium to long-term storage.

Port Grain Terminals

Grain export/import terminals at ports that need to adjust grain moisture to meet shipping specifications or prepare grain for overseas transport.

Large Commercial Farms

Very large commercial farming operations with extensive grain production (500+ hectares) that benefit from on-site drying to maintain quality and reduce transport costs for wet grain.

Seed Processing Companies

Seed production and processing companies requiring gentle, controlled drying to maintain seed viability, with the capacity to handle commercial seed volumes.
