ABSTRACT:
A self-contained apparatus (20, 100, 200) for making an ice cream type mixture includes a mixing chamber or container (22, 103, 222) which is controllably cooled by a refrigeration unit (50, 50, 50") including a coil (52, 52', 52") surrounding the container (22, 103, 222). A blade (32-36, 105, 208-209) such as a flexible blade, is rotatably driven in the container (22, 103, 222) by a motor (28, 28', 28") and may preferably include an angled multifunction blade (32) and a scraper blade (36). The multifunction blade (32) primarily performs three functions of forcing the mixture contents downwardly toward the base wall (33) and forcing these contents outwardly from the center (26) toward the side wall (35) and kneading the ingredients while the scraper blade (36) forces those contents upwardly from the base wall (33) and from the side wall (35) toward the center (26) thereby cyclically intermixing the warmer and colder contents and providing a substantially uniform temperature gradient for the mixture. The base wall (233) of the chamber (222) may also include protruding ribs (207) which cooperate with the flexible blade (209) to crush or shred fruit added to the mixture. The apparatus (100) may also include a heater coil 106 surrounding the container 103 for selectively heating the contents to be mixed instead of refrigerating them, as well as a separate container (107) and blade 109 for blending vegetables with the blade 109 being selectively driven by the same motor (28') which drives the blade (105) associated with the other container (103).
