    1. Inside and outside of barrel are both made of stainless steel, and the middle layer is heat preserving material, the production efficiency is 2~3 times higher than the average machine,it can reduce 25% energy consumption.
    2. The baiting system includes first time baiting device and second time baiting device.
    3. This machine can process secondary pre-expansion.
    4. The expanded density range of foamed beads is 7~30 KG/M³,the density tolerance is minimal.
    5. Steam pressure reducing valve is optional.
