General function

The blow-through rotary valve (B) doses the raw material to the transport pipeline (F). There, the transported goods get catched by the air stream and are blown or sucked to the receiving point. Depending on the transport pipeline length and the number of pipe bends and rotary valves (B), the transport blower (C) is selected. The control provides pre-threshold point calculation and regulation for a completely empty piping.


For non-abrasive transport materials, the transport line is constructed in aluminium. For abrasive transport materials (e.g. sugar, salt, ...), the transport lines and product contacting parts must be constructed in stainless steel.
