Patent ID: 8708549

Claim:
A mixing system for use with viscous substances, comprising: (a) a mixing apparatus; (b) a mixing bowl mounted within the mixing apparatus, wherein the mixing bowl further includes: (i) a curved bowl sheet; and (ii) a cooling jacket mounted on the curved bowl sheet, wherein the cooling jacket further includes a plurality of channel forming structures running parallel to one another across the length of the bowl sheet, and wherein each of the plurality of channel forming structures further includes: (a) at least one substantially vertical side portion, relative to the surface of the bowl sheet; and (b) a substantially horizontal top portion relative to the surface of the bowl sheet, wherein the substantially top horizontal portion is elevated above the surface of the bowl sheet, and wherein the horizontal top portion further includes a contoured region having a plurality of parallel ridges and parallel valleys formed therein and running lengthwise therethrough; and (c) wherein each channel forming structure defines a channel for receiving liquid coolant; and (iii) a plurality of pins positioned within the channels, wherein the pins are positioned vertically relative to the surface of the bowl sheet; wherein each pin in the plurality of pins is mounted either on the substantially horizontal portion of the channel forming structure or on the surface of the bowl sheet, and wherein each pin in the plurality of pins further includes an end which is fully exposed to the channel; and (c) a source of liquid coolant, wherein the source of coolant is in fluid communication with the cooling jacket for reducing the temperature of a viscous substance being mixed during the mixing process, and wherein the pins positioned within the channels are operative to induce turbulence in the liquid coolant, and wherein each of the plurality of pins increases the cooling surface of the cooling jacket by greater than 0.5 square inch per pin.
