Abstract:
An apparatus for making a frozen confection product, comprising:(a) a freezing barrel having a first end and a second end with a dispensing aperture formed therein; (b) a liquid mix container; (c) a pump for providing liquid mix from the liquid mix container to the first end of the freezing barrel at a liquid mix delivery rate; (d) a dasher positioned in the freezing barrel for rotational movement therein; (e) a dasher motor coupled to the dasher to drive the dasher at a dasher speed to propel the frozen confection product through the freezing barrel and out of the dispensing aperture at a selected product production rate; (f) a refrigeration system for chilling the freezing barrel to a chilling level; (g) a user interface enabling a user to select between at least a high production rate and a low production rate; and (h) a system controller coupled to the user interface, the pump, the dasher motor, and the refrigeration system and adapted automatically to control the pump to pump liquid mix at a first delivery rate in response to a user selecting a high production rate and to control the pump to pump liquid mix at a second delivery rate in response to a user selecting a low production rate, wherein the first delivery rate is higher than the second delivery rate, to control the dasher motor to drive the dasher at a first dasher speed in response to a user selecting a high production rate and to control the dasher motor to drive the dasher at a second dasher speed in response to a user selecting a low production rate, wherein the first speed is higher than the second speed, and to control the refrigeration system to chill the freezing barrel to a first chilling level in response to a user selecting a high production rate and to control the refrigeration system to chill the freezing barrel to a second chilling level in response to a user selecting a low production rate, wherein the first chilling level is at a lower temperature level than the second chilling level.
