  • a continuous whipped creammaking machine such as that shown in FIGS. 1 and 2, comprises a preferably heat-insulated and refrigerated liquid cream container or tank I mounted on a suitable frame and provided with a drain opening closed by a plug 3 provided with a gripping stem 31 and to which opening a drain tube 2 is connected, which opens in a drain container B.
  • This drain container as it appears from the drawing, is arranged preferably below a whipped cream-dispensing piston cock C and serves also for collecting any cream or like drops falling down from the cock.
  • a gear pump 5 is mounted, which is driven by an electric motor M through a conventional pulley-and-belt transmission T.
  • Pump 5 has its suction side connected to an air intake 4 and a liquid cream draw pipe 6 opening in proximity of the tank bottom.
  • the delivery side of the pump opens into the inlet end of an open ended emulsifying homogenizer E which, according to the invention, is provided with a preferably conical shell 7 ending at its inlet and outlet ends with two cylindrical necks I07 and 207, the first for inserting with a tight fit into the delivery port of pump 5 and the other for inserting also with a tight fit into a sleeve 13 provided with a rubber ring packing and constituting the fastening member of a cock C and for example the piston cock as shown.
  • This is supported by a pair of arms 19 and is fastened by means of a bolt 20.
  • This piston cock C whose construction is known, is preferably arranged in proximity of a pushbutton switch Sw which, each time the piston P is in its opening position, with its top end operates the switch and starts the motor M, while when the piston is shifted to its closing position, interrupts the current to said motor.
  • the emulsifying homogenizer E comprises a conical shell 7 with cylindrical end sections 107 and 207, in which a conical core 8 provided at its surface with parallel annular ribs 18 is fitted.
  • a ball valve 10 is adapted to close the inlet port II connected to the delivery of pump 5 (see arrow).
  • the front end 108 of the core 8 is tumbler-shaped and contains a helical pressure spring 9 reacting against a shoulder of the piston cock casing, above the piston cock inlet 12.
  • both the slits in correspondence of the ribs and the annular overflow spaced between adjoining ribs become of increasing total flow area, thus permitting the expansion of the creamandair emulsion, as does the conventionally prepared whipped cream.
