Publication number: 20020158086Abstract: A unit for discharging loose material from a dispensing device to a user unit comprises a discharge tube leading to the user unit and a valve element connecting the dispensing device to the infeed end of the tube. The valve element comprises a first annular element equipped with a shutter device, consisting of a first shutoff element and a second shutoff element connected to each other by permanent magnets, and a second annular element connected to the infeed end of the tube. When the first and second annular elements are separated by the operation of pistons, a gap is created between the two shutoff elements. A pair of concentric seals positioned between the first and the second annular elements isolate the gap from the outside environment so that a cleaning fluid can be made to flow into it.Type: ApplicationFiled: April 18, 2002Publication date: October 31, 2002Applicant: ZANCHETTA & C.

Publication number: 20010047594Abstract: A certain quantity of product to be dried, in powder or granular form, is sucked into a vessel located inside a vacuum container. The vessel is heated by a heat transfer fluid circulating in a gap made between an inner wall and an outer wall of the vessel. The vessel is made to vibrate by a vibrator so that the product comes constantly into contact with the heated inner wall in such a way that the product is dried.Type: ApplicationFiled: December 13, 2000Publication date: December 6, 2001Applicant: Zanchetta & C.

Patent number: 5934517Abstract: A system for unloading loose materials from containers is fitted with a cartridge that defines a containing chamber for a tubular bag gathered in a resting position. The cartridge can be connected with an upper end to an outlet presented by a container to be emptied and the lower end presents a flange or cap that can be coupled to a connector arranged downstream. The system may also include a two-way drive mechanism for the flange or cap through a tube arranged between the container and the devices to be connected. The drive mechanism is designed to pass the bag, itself, extended in an operating position and to transfer the flange or cap outside the tube so as to allow the connection between the tubular bag and the devices to be connected.Type: GrantFiled: May 29, 1997Date of Patent: August 10, 1999Assignee: Zanchetta & C. S.r.L.Inventor: Luciano Pieri

Patent number: 5011640Abstract: One or more powders are placed in a leaktight vessel (12) having a substantially vertical axis and comprising a bottom blade rotating about an axis parallel to the axis of said vessel, and a spheronizing tool (28) having a substantially discoidal rotating form; said powders are mutually mixed by means of the rotation of said bottom blade, and a binder solution is added thereto. The composition of mixed powders thus added to is spheronized by immersing said spheronizing tool (28) in said composition and causing it to rotate simultaneously with said blade (18).Type: GrantFiled: March 1, 1990Date of Patent: April 30, 1991Assignee: Zanchetta & C.
