Pre-Expander

It is controlled by PLC full computer touch displayer which can realize a full auto-cycle operation of material feeding ,steam feeding ,temperature controlling, foaming and discharging, and the quantitative material is exactly and rapidly fed after compressed .The foaming process in the machine is realized in a fully closed stainless steel barrel under constant pressure with high thermal efficiency, economized steam, shortened curing process and high foaming magnification. the machine is composed by famous-brand and high-quality pneumatic elements which can supply a reliable quality and convenient operation to ensure a precise temperature control and uniformity of beading and density .this machine can be matched with fruit dryer to realize a continuous operation of drying,screening,breaking and conveying of material for foaming.

The adoption stainless steel plank creates, the construction is good, easy to maintain, adjust in to anticipate, To reach the grain needed permit heavy.
