- energy saving, -even density distribution, -full automatic, -PLC+Touch Screen Control.

-  Stainless steel vessel insulated for heat retention with steam chamber below the vessel.  .

-  Stainless steel perforated plates with 0.3mm venting to allow optimal steam distribution from steam chamber to pre-foaming vessel.

-  Precision PLC programmable controller and touch screen are used for full-automatic production as automatic material feeding, electronic weighing system, temperature controlling and photo-electric level controlling.

-  Automatic material feeding equipment and electronic weighing equipment are used. Accurate weighing system can guarantee exact raw material dosing.

-  Close pre-expander tank with double venting outlets is used for even pre-expansion in constant temperature to ensure high heat efficiency and steam saving.

-  With precise control valve units ensure accurate temperature controlling at ± 1C and uniform beads pre-expanding with low moisture content.

-  Photo-electric level controllers control the volume of pre-foaming material and even density with tolerance less than ±2%.

-  The machine is equipped with fluidizing bed. The process of drying, fluidizing, de-lumping and conveying to the ageing silos is automatic.

-  Star feeder device facilitates the transport distance and no deformity of unstable beads.

-  Capacity depending on type of raw material used.
