  • Bowl cooling jacket 40 may be constructed using the following exemplary manufacturing method. This method is exemplary in nature and is not meant to be limiting in any way as other manufacturing methods are useful for constructing or assembling the bowl cooling jacket of the present invention. Following the mounting of bowl sheet 30 on mixing bowl 20, a series of visible marks are etched or otherwise scribed on the outer surface of bowl sheet 30 for use as guide lines. These guide lines facilitate proper placement of channel forming structures 51 and 61 on the surface of bowl sheet 30. Following the creation of the guide lines, jacket side rail 70 is welded onto the surface of bowl sheet 30 in an orientation generally perpendicular to the aforementioned guide lines (see FIGS. 3b and 4b).
  • jacket side rail 70 is a piece of sheet metal that has been laser cut to match the profile of bowl sheet 30.
  • Jacket side rail 70 seals the ends of channel forming structures 51 and 61 to create sealed channels 50 and 60.
  • channel forming structures 51 single-break
  • a double-break structure 61 is typically the final channel forming structure mounted on bowl sheet 30 (see FIG. 6a) for purposes of completing bowl cooling jacket 40.
  • a second jacket side rail 70 is mounted on the opposite side of bowl sheet 30 such that both ends of the various channel forming structures are sealed.
  • channel forming structures 51 and 61 are typically preformed from metal plates using a hydraulic brake or similar device.
  • the actual number of channel forming structures (51, 61) mounted on bowl sheet 30 will vary based on conditions such as ambient air temperatures, dough ingredient temperatures, mixing speeds, and desired dough-out temperatures.
  • the maximum number of channels possible is mounted on bowl sheet 30 to provide maximum flexibility with regard to temperature control.
  • refrigerant inlet port 90 and outlet port 92 be mounted on the same end of mixing bowl 20.
  • Such a configuration may be achieved through the use of jacket return channel 72 (see FIG. 4b), which allows liquid coolant to enter bowl cooling jacket 40 at rear portion 44, flow from rear portion 44 to front portion 42, then flow from front portion 42 back to rear portion 44 (see FIGS. 3c and 4c).
  • Jacket return channel 72 is typically constructed from two side by side jacket side rails 70 to which jacket return channel cover 74 has been welded to form a sealed channel. Following construction of the various channels on the surface of bowl sheet 30, pressure testing of bowl cooling jacket 40 is performed to identify leaks or other structural issues.
  • wrapper sheet 80 is welded onto mixing bowl 20.
  • Wrapper sheet 80 provides a polished, aesthetically pleasing exterior surface to mixing bowl 20.
  • insulating material such as foam insulation, may be placed between the outer surfaces of the various channel forming structures and the inner surface of wrapping sheet 80 to reduce the loss of the cooling effect to ambient air.
  • the bowl cooling jacket of the present invention utilizes a configuration that differs from known cooling jackets, which are typically designed to maximize jacket stiffness for resisting dough forces experienced inside the mixing bowl during the mixing process.
  • the use of a stiff or rigid cooling jacket often creates high stress regions in critical areas of the jacket thereby increasing the likelihood of weld cracks that may allow refrigerant to leak from the bowl cooling jacket.
  • the present invention includes a channel design that allows for the manufacture of a bowl cooling jacket possessing increased structural strength and fatigue resistance characteristics, while still maintaining sealed channel flow patterns for a liquid coolant.
  • each channel forming structure 51, 61 of bowl cooling jacket 40 includes multiple lengthwise breaks or bends 54, 55, 64, 65 formed therein for providing increased strength, flexibility, and fatigue resistance to bowl cooling jacket 40.
  • Such performance characteristics are accomplished through the transfer of stress concentrations from weld (fastening) joints 56, 66 and bowl sheet 30, to the material that forms channels 50 and 60.
  • the contoured profiles of channel forming structures 51 and 61 allow the entire bowl cooling jacket 40 to act as a "spring" rather than a highly rigid body.
