Machine for washing and/or sterilizing supplying-batching devices

A machine for washing and/or sterilizing a supplying-batching device having a hopper, piston batching means having movable pistons for delivering batched quantities of a product therefrom, and supplying means having a commutation valve and supplying nozzles for delivering product therethrough, said piston batching means communicating with said supplying nozzles through said commutation valve, the machine comprising:

• an enclosing structure enclosing a receiving station having supporting means for supporting the supplying-batching device to be washed and/or sterilized;
• fluid feeding means located within the enclosing structure and being connectable to said hopper of said supplying-batching device for feeding washing fluids thereto;
• working means situated inside the enclosing casing structure which are connectable to said piston batching means and said supplying means of said supplying-batching device, said working means operating the supplying-batching device to reproduce a working cycle of said piston batching means and said supplying means, so as to perform one or more working cycles as said washing fluids are fed to said hopper,
• said working means including piston working means comprising a cross bar, situated in a lower part of said enclosing structure and having coupling means which are fastenable to said pistons, said cross bar being translatable by motor means so as to displace the pistons during the washing and/or sterilizing of the supplying-batching device, and gripping means fixable to said commutation valve, activating means connected to the gripping means for angularly rotating said gripping means and said commutation valve during the washing and/or sterilizing of the supplying-batching device, and,
• a plurality of channels provided within the enclosing structure for receiving discharged washing fluids from the supplying means of said supplying-batching device.
