A machine for dispensing a soft-serve product comprises a freezer barrel (12), a mix hopper (14) for containing soft-serve mix (16) and being in flow communication with the freezer barrel so that soft-serve mix can flow from the mix hopper into the freezer barrel, a flow passage (42, 42.1) leading from the freezer barrel to a draw spout (64), and a beater assembly (20) for expelling frozen product from the freezer barrel via the flow passage to the draw spout. A solids hopper (52) for containing a flowable solid topping is further provided, and an archimedes screw (56) for feeding the solid topping from the solids hopper into the flow stream of soft-serve product as it passes through the flow passage. A vaned rotor (44) and a rotation sensor (80) meter the flow of soft-serve product through the flow passage and control the speed of a topping motor (60) driving the archimedes screw.
A machine for dispensing a soft-serve product, the machine comprising a freezer barrel, a mix hopper for containing soft-serve mix and being in flow communication with the freezer barrel so that soft-serve mix can flow from the mix hopper into the freezer barrel, a draw spout, a primary flow passage leading from the freezer barrel to the draw spout, means for expelling frozen product from the freezer barrel via the primary flow passage to the draw spout, a solids hopper for containing a flowable solid food product, a plunger for openably closing the primary flow passage and having a secondary flow passage therein, the secondary flow passage leading from the solids hopper into the primary flow passage, and feed means for feeding said solid food product from the solids hopper via the secondary flow passage into the flow stream of soft-serve product as it passes through said primary flow passage.
A machine for dispensing a soft-serve product, the machine comprising a freezer barrel having a front end, a removable door plate closing the front end, a mix hopper for containing soft-serve mix and being in flow communication with the freezer barrel so that soft-serve mix can flow from the mix hopper into the freezer barrel, a draw spout, a flow passage leading from the freezer barrel through the door plate to the draw spout, means for expelling frozen product from the freezer barrel via the flow passage to the draw spout, and flow metering means for metering the flow of soft-serve product through the flow passage, the flow metering means comprising a vaned rotor in the flow passage at a location where the flow passage passes through the door plate, and sensing means for sensing rotation of the vaned rotor.
A machine as claimed in claims, which includes numerical display means, the numerical display means being operative in response to the flow metering means to display a numerical quantity corresponding to the flow of soft-serve product through the flow passage.
