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to a motor shaft (2) and a pump casing (9) together with the whipping barrel (26) and intake assembly (16), may be withdrawn from the rotor by undoing bolts (11).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.
Abstract:
The machine includes a motor-driven pump having an inlet operatively connected both to an air intake and to an unpressurized liquid product container, whereby the liquid product and air are simultaneously drawn into the pump. An adjustable needle valve is provided at the air intake to control flow of air into a chamber which has a check valve at its outlet. The pump outlet is connected to a static, narrow-orifice homogenizer which emulsifies the liquid and air mixture. A solenoid-operated valve is located at the outlet of the homogenizer and an electrical control system simultaneously opens the valve and starts the motor.

THE MACHINE INCLUDES A MOTOR-DRIVEN PUMP HAVING AN INLET CONNECTED BOTH TO AN AIR INTAKE AND TO AN UNPRESSURIZED LIQUID PRODUCT CONTAINER, WHEREBY THE LIQUID PRODUCT AND AIR ARE SIMULTANEOUSLY DRAWN INTO THE PUMP. THE PUMP OUTLET IS CONNECTED TO A STATIC, NARROW-ORIFICE HOMOGENIZER WHICH EMULSIFIES THE LIQUID AND AIR MIXTURE. A SOLENOID-OPERATED VAVLE IS LOCATED AT THE OUTLET OF THE HOMOGENIZER AND AN ELECTRICAL CONTROL SYSTEM SIMULTANEOUSLY OPENS THE VALVE AND STARTS THE MOTOR.
Abstract:
An ice dispensing machine having an insulating casing with a platform adjacent the bottom for supporting a mass of flaked ice with a rotatable impeller mounted adjacent the bottom of the mass of ice to shave the ice therefrom and direct such ice to a vertically extending conveyor for carrying the ice upwardly to a discharge spout with a receptacle actuated lever for starting the operation of the impeller and conveyor.
