A flavor mixing and dispensing device for a frozen confection machine including an upright valve cylinder having a discharge outlet at its lower end and a frozen confection inlet port and a plurality of flavoring inlet ports spaced above its lower end. A rotary mixer is provided in the lower portion of the cylinder and a valve piston is slidable in the valve cylinder. The valve piston is formed with a downwardly opening cavity means for receiving the rotary mixer, and the rotary mixer and valve piston are constructed and arranged so that the mixer telescopes into the cavity means in the valve piston when the piston is moved to its lower position, and the mixer and valve piston substantially fill the mixing chamber in the lower portion of the valve cylinder to displace substantially all material from the valve cylinder at the end of a dispensing operation.

A flavor mixing and dispensing device for a frozen confection machine comprising, a valve body adapted for mounting on the discharge end of a frozen confection freezer and having an upright valve cylinder therein, the lower portion of the valve cylinder defining a mixing chamber and having a discharge outlet at the lower end of the mixing chamber, a frozen confection inlet port opening into the valve cylinder at a location spaced above the discharge outlet and adapted to receive frozen confection material from the frozen confection freezer, at least one flavor inlet port opening into the valve cylinder at a location spaced above the discharge outlet and adapted for connection to a source of flavor material, a rotatable mixer shaft extending axially of the valve cylinder and drive means connected to the upper end of the shaft for rotating the mixer shaft, a rotary mixer means mounted on the lower end of the mixer shaft and disposed in the mixing chamber with the lower end of the rotary mixer means adjacent the discharge outlet, piston means mounted for sliding movement in the valve cylinder between a lower position in which the lower end of the piston means is adjacent the discharge outlet and a raised position in which the lower end of the piston means is spaced above the discharge outlet sufficient to allow frozen confection material and flavoring material to enter the valve cylinder from the respective confection inlet port and flavor inlet port, the rotary mixer means having vane means operative when the piston means is in its raised position to mix frozen confection material and flavoring material in the mixing chamber, the piston means including means defining a downwardly opening cavity means movable vertically with the piston means for telescopically receiving the mixer means when the piston means is moved down to said lower position, the mixer means and piston means being so constructed and arranged that, when the piston means is moved to said lower position with said mixer means telescoped into said cavity means, the piston means and mixer means substantially fill the space in the mixing chamber to displace substantially all confection and flavoring material from the mixing chamber.
