FAQ
Ambient air is drawn through a product bed in the opposite direction to product flow, providing efficient heat exchange and gentle cooling to near-ambient.
For frequent product change-overs. The intermediate deck holds the new product while the previous batch completes its cycle, shortening waiting time.
Triple-grid dischargers (electrically driven) for free-flowing pellets, and swivel-valve dischargers (hydraulically driven) for a wider product range, including expandate and full-fat soya.
They use two fluidised beds with dedicated distribution and discharge to cool dense mash uniformly. The standard design can be adapted to handle both meal and pellets if required.
Yes. The discharge systems are designed for smooth emptying and total discharge at the end of a run.
