Solex heat exchanger technology is capable of handling any relatively free-flowing powder or crystalline bulk solids, making it the perfect candidate to cool biosolids such as:
- Sludge granules
- Sludge pellets
- Wood chips
- Wood pellets
Our heat exchangers can cool biosolids to uniform temperatures while using up to 90% less energy when compared with direct cooling methods.
For biosolids such as sludge granules and pellets, the material must be stabilized following the mechanical heating and drying process to prevent decomposition and possible smoldering or auto ignition. Solex accomplishes this stabilization by cooling the biosolids indirectly via conductivity, thus preventing fires or explosions in the subsequent handling and storage stages, as well as ensuring each particle is thermally stable through its core.
For other biosolids such as wood pellets, the cooling stage represents a critical step that requires the ability to accurately and evenly reduce temperatures and moisture levels while avoiding breakages and the production of additional fines. Solex heat exchanger technology ensures optimal product temperature at the outlet to the required parameters of 3-5°C above room temperature and moisture content between acceptable ranges. The even distribution of heat transfer to every pellet has multi-fold advantages, from mitigating spoiled product to creating a safe handling environment during storage and transport.
