Filling (Liquids+Solids)

External Valve Vacuum Fillers are suitable to fill liquid or thick products, with or without suspended solids. Vacuum Fillers are designed to fill up metallic or glass recipients that already contain solid product, with a preserving liquid such as brine. Vacuum Fillers are classified as “internal valve” when the filling valves are inside the tank and as “external valve” when the valves are outside. The Vacuum Fillers are equipped with a system to create vacuum by means of a dedicated pump and rotary distributor.  This system expels the air from the containers and then fills them up with the preserving liquid. During its operating cycle, a table top chain conveyor leads the containers to the variable pitch feeding worm screw that facilitates their introduction. The feeding worm screw is synchronised with the inlet star that transfers the containers to the Filler. At the beginning of the filling area, the containers activate the “no can – no fill” device for access to the first phase of the operating cycle. The filling operation is regulated by a lever that commands the opening of the filling valve to allow the preserving liquid to flow from the tank into the containers. Once the final phase is complete, the containers are transferred to the Seamer or Capper.

Volumetric Piston Fillers with Rotary Valves are suitable to fill liquids (with or without pieces) or viscous products such as: tomato paste, jams, marmalade, fruit juices and purees, vegetable and mineral oils in glass, metallic or plastic containers. During the machine operating cycle, a table top chain conveyor with feeder-screw and a feeder star convey the containers to the filling zone. A moving piston guarantees the filling process as it intakes the product from the storage tank to fill the container.  A two-way cock connects the piston dosing chamber with the product storage tank  and with the empty container afterwards. The quantity of product to intake can be modified, even when the machine is working, by changing the piston stroke. The machine is supplied with the ‘no can – no fill’ device according to which the cock is opened only in case there is a container to be filled. Once the filling is completed, the container is transferred to the following processing phase through an outlet conveyor.

Linear Volumetric Piston Fillers are suitable to fill liquid or semi-thick products containing pieces in suspension, into glass, metallic or plastic container. During its operating cycle, the containers are conveyed by a feeding belt to the variable pitch infeed worm screw, driven by a servomotor that spaces and synchronises them with the filling pistons. Filling is obtained through the movement of a piston, that fills the container in the downward stroke and draws up the product to be dosed from the storage tank in its upward stroke. A two-position plug connects the piston’s dosage chamber to the product storage tank and subsequently with the container to be filled. The pistons are driven by a servomotor and take up the required amount of product from the tanks. The sensors, positioned at the worm screw’s inlet, allow the machine to be stopped in the absence of containers.
