| 20080264091 | Tumble chiller - A tumble chiller has a rotary drum with a perforated side wall. The drum is enclosed by a cooling jacket through which coolant such as ethylene glycol may be passed. Cooling liquid such as water or brine fills the drum. The drum has scoop-like projections which cause the cooling liquid to flow across the cooling jacket as the drum rotates. The cooling liquid may follow a path around the inner side of the jacket and then follow a path around its outer side. The drum is drivable in rotation by sprocket meshing with a roller chain fast with a flange at the rear end of the drum. | 10-30-2008 |
