Material in mixed material in first reactor and firming agent measuring tank is transported to low-temp foaming area foamed, when first
After reactor discharging is finished, the automatically controlled control valve of the second reactor outfan after main controller controls material mix homogeneously is opened
Dynamic, discharging program is carried out, the material after foaming enters step F；
F, down-stream：Material after foaming is transported to the sizing of high-temperature shaping area by conveying mechanism, goes out from protective cover after sizing
Material mouth is exported, and carries out cutting packaging operation after being then sent to cooling zone cooling；
G, shutdown procedure：After completing production task, stop step C accounting procedure, the first reactor, the second reactor material go out only
Afterwards, stop step D filling operation, step E discharging program, the electric control valve of firming agent measuring tank outfan is closed, treats material
After being exported from protective cover discharging opening completely, heating-stopping apparatus, after post-processing operation to be done, close master controller.
