Vigan

The principle of VIGAN pneumatic unloader is the following:

In the hold, the products are sucked into the vertical pipes which have telescopic movement capability. A sufficient air turbulence by the suction system will allow to move the products upwards.


Flowing by the elbow towards the horizontal telescopic pipes, the products will enter into a receiving hopper where an airlock (or also called rotary valve) will convey the products downwards.


The sucking air will be cleaned by a jet pulse type filter before entering into the vacuum producing system by centrifugal type turbo blower(s).


In the tower type VIGAN unloaders, the boom that supports the suction pipes, the filter and the airlock are rotating on a slewing ring: the main engine room with the turbo blower(s) is stationary.

VIGAN tower type machines are specially suited to handle products in bulk for the following most common applications:
