Functioning

Machine suitable to fill glass / metal / PET containers with dense or semi-dense products (sauces, cremes, paté, "pesto alla Genovese", tomato sauces, ketchup, mayonnaise, mustard, purées, baby food, honey, jam, etc.).
 
Containers feeding by a conveyor belt and a stop device which positions the containers under the dosing valves with a screw in polyzene and supports adjustable according to the containers’ diameter.
After the filling  the containers are moved by the same conveyor to the other machines in the line.
The dosing pistons, integral with the actuators, have a pre-set stroke which is electronically set by means of the operator panel equipped with a 6” colour LCD Touch Screen display. The pistons aspirate the product from the tank and push it, by means of the diverting valves, to the second plunging valves for the filling of the container from the bottom so as to avoid the possible formation of air bubbles during the filling of viscous products like mayonnaise, dense sauces, etc. and splashes of liquid products like fruit juice, etc. 
The plunging valves are fitted with a device which allows to empty the nozzles completely so as to avoid that the product remains suspended.
These valves carry out the filling from the bottom. They are connected to a mechanical actuator driven by a brushless motor, this allows to regulate their lifting speed according to the type of product / container to be filled.
The filling volume is adjustable from the control panel according to pre-set recipes and the type of container to be filled. If necessary, it is possible to intervene on the operator’s panel to optimise the filling volume precision even with the machine in operation.
