Main Features
1. Insulated stainless steel vessel with (l.3mm laser perforated Stainless Steel steam venting plate. It reaches above 85% permeability.
2. Full automatic operation is realized by PLC with touch screen. Advanced data memory function can retrieve batching data of various type pre-expansion materials.
3. Automatic material transport feeding screw and electronic weighing device.
4. Close pre-expander vessel with balance flue double venting outlets. Precious controlling valves provide accurate pressure and temperature. Pre-expanding level is controlled by high performance inductive proximities switches.
5. High Performance pre-expander is equipped with complete stainless steel fluidizing bed to ensure stabilization of beads before transport to silos for ageing. It combines with drying compartment, sieving unit, de-lumper and material transport station.
6. Even density distribution with less than l.5% tolerance.
