Abstract
A cream whipping machine has an electric motor (1), a vane pump (3,9) and a whipping barrel (26) fitted closely together in axial alignment. Air and cream are sucked in to the pump chamber (14) via an intake assembly (16). A pump rotor (3) is fixed to a motor shaft (2) and a pump casing (9) together with the whipping barrel (26) and intake assembly (16), may be withdrawn from the rotor by undoing bolts (11). A space (13) to the motor side of a main pump seal (8) is vented to atmosphere through an opening (12) so that if the seal fails the liquid product is not forced into the motor.
Claims10
A machine for producing aerated food products comprising a motor-driven pump having an inlet connected both to an air suction intake and to a liquid product suction intake which is, in use, connected through a suction tube to an unpressurised liquid product container, whereby in use liquid product and air are simultaneously drawn into said pump, said pump having an outlet connected to a product discharge outlet through a flow path which incorporates a static homogenizer for emulsifying the mixture;
- wherein said motor and said pump are arranged end to end with the axes thereof substantially horizontal;
- a rotor of said pump is carried by and fixed to a driven shaft of said motor;
- and a space between a seal at the end adjacent to said motor of a pump chamber, in which said rotor works, and said motor is vented to atmosphere via vent means.
