Abstract
Description

- Filling plants for the filling of pourable food products, in particular sterilized and/or sterile-processed pourable food products, are known.
- A typical filling plant comprises a processing apparatus configured to process and/or prepare and/or treat the pourable food product and a filling apparatus configured to receive the pourable food product from the processing apparatus and to fill the receptacles with the pourable food product.
- A typical filling plant also comprises a process valve, which is configured to allow or impede the flow of the pourable food product from a first flow circuit of the processing apparatus to a second flow circuit of the filling apparatus and a flow control valve arranged within the second flow circuit and configured to control the flow rate of the pourable product flowing from the first flow circuit to the second flow circuit.
- In particular, the process valve is configured such to isolate the first flow circuit from the second flow circuit when impeding the flow from the first flow circuit to the second flow circuit. Even more particular, the process valve comprises an inlet and an outlet, valve plugs for opening and closing the inlet and the outlet and means for introducing a sterile gas into at least a portion of the flow conduit interposed between the inlet and the outlet. In this way, when closing the inlet and the outlet, the presence of the sterile gas guarantees the isolation of the first flow circuit and the second flow circuit from one another even if the inlet and the outlet are not perfectly closed, which may e.g. be due to material defaults of e.g. the valve plugs and/or the respective valve seats or any other reason, which may allow for an undesired fluid connection between the first flow circuit and the second flow circuit if it was not for the sterile gas introduced into the process valve.
