The opening of the product and of the vacuum are done with pneumatic controls.
It is composed by the product feeding tank and the vacuum generation tank.
The level control is based on capacitive level probe and modulating valve.
To have the product tank outside the machine allows its easy inspection and cleaning.
In special cases, like the one shown in the picture, it is possible to have two tanks for two different products.
The carousel has two central small manifolds for the product (lower manifold) and vacuum distribution (upper manifold).
This solution allows eliminating the traditional central tank difficult to be accessed.
The filler is equipped with a collection tray that can be inserted in an arc of the carrousel to empty the machine at the end of the production and recover the product.
The tray can also be used to flush the filling valve during cleaning operations and collect the washing product.
The machine can be equipped with a system to adjust with a motorized solution the position of the stopper that determinates the level in the bottle (position of the vent pipe respect to the bottle) .
The system is studied not to have gears in the filling valve, to guarantee clean conditions for the cleaning.
