(a) a first horizontal rail mounted lengthwise across the top portion of the rear section of the bowl sheet;
(b) a second horizontal rail mounted lengthwise across the top portion of the front section of the bowl sheet;
(c) a plurality of vertical rails mounted on the rear section of the bowl sheet in a staggered pattern;
(d) a plurality of vertical rails mounted on the front section of the bowl sheet in a staggered pattern;
(e) a plurality of horizontal rails mounted across the bottom portions of the rear and front sections of the bowl sheet, wherein each rail in the plurality of horizontal rails is mounted between and perpendicular to certain of the vertical rails mounted on the rear section of the bowl sheet and certain of the vertical rails mounted on the front section of the bowl sheet,
(i) wherein the first and second horizontal rails, vertical rails, and horizontal rails mounted between certain of the vertical rails define a first coolant channel on the rear section of the bowl sheet and a second coolant channel of the front surface of the bowl sheet;
(f) a first plurality of channel covers mounted to the vertical rails on the rear section of the bowl sheet and a second plurality of channel covers mounted between and to the channel covers in the first plurality of channel covers, wherein the first and second plurality of channel covers are operative to completely enclose the first coolant channel;
(g) a third plurality of channel covers mounted to the vertical rails on the front section of the bowl sheet and a fourth plurality of channel covers mounted between and to the channel covers in the third plurality of channel covers, wherein the third and fourth plurality of channel covers are operative to completely enclose the second coolant channel; and
(h) a horizontal cross-channel formed on the front section of the bowl sheet above the second horizontal rail, wherein the cross-channel is operative to permit fluid coolant to flow from one side of the cooling jacket to the other side of the cooling jacket on the front section of the mixing bowl.
2. The cooling jacket of claim 1 , further comprising a fluid inlet, wherein the fluid inlet is operative to introduce fluid coolant into the cooling jacket; and a fluid outlet, wherein the fluid outlet is operative to allow fluid coolant to exit the cooling jacket.
3. The cooling jacket of claim 1 , wherein the first coolant channel is in fluid communication with the second coolant channel for permitting fluid coolant on the rear section of the bowl sheet to cross from the rear section of the bowl sheet to the front section of the bowl sheet.
4. The cooling jacket of claim 1 , wherein the cooling jacket is constructed from metal components that have been welded together, and wherein the welds between the components are lap welds.
5. The cooling jacket of claim 1 , wherein the cooling jacket is adapted for use with either an indirect refrigeration system or a direct refrigeration system.
6. A cooling jacket for use with an industrial mixer, wherein the industrial mixer includes a bowl sheet as a component thereof, wherein the bowl sheet includes an internal surface that defines a cavity for receiving material to be mixed and an external surface having a front section and a rear section, wherein the front section further includes a top portion and a bottom portion, and wherein the rear section further includes a top portion and a bottom portion, the cooling jacket comprising:
(a) a first horizontal rail mounted lengthwise across the top portion of the rear section of the bowl sheet;
(b) a second horizontal rail mounted lengthwise across the top portion of the front section of the bowl sheet;
(c) a plurality of vertical rails mounted on the rear section of the bowl sheet in a staggered pattern;
(d) a plurality of vertical rails mounted on the front section of the bowl sheet in a staggered pattern;
(e) a plurality of horizontal rails mounted across the bottom portions of the rear and front sections of the bowl sheet, wherein each rail in the plurality of horizontal rails is mounted between and perpendicular to certain of the vertical rails mounted on the rear section of the bowl sheet and certain of the vertical rails mounted on the front section of the bowl sheet,
(i) wherein the first and second horizontal rails, vertical rails, and horizontal rails mounted between certain of the vertical rails define a first coolant channel on the rear section of the bowl sheet and a second coolant channel of the front surface of the bowl sheet;
(f) a first plurality of channel covers mounted to the vertical rails on the rear section of the bowl sheet and a second plurality of channel covers mounted between and to the channel covers in the first plurality of channel covers, wherein the first and second plurality of channel covers are operative to completely enclose the first coolant channel; and
(g) a third plurality of channel covers mounted to the vertical rails on the front section of the bowl sheet and a fourth plurality of channel covers mounted between and to the channel covers in the third plurality of channel covers, wherein the third and fourth plurality of channel covers are operative to completely enclose the second coolant channel.
7. The cooling jacket of claim 6 , further comprising a fluid inlet, wherein the fluid inlet is operative to introduce fluid coolant into the cooling jacket; and a fluid outlet, wherein the fluid outlet is operative to allow fluid coolant to exit the cooling jacket.
8. The cooling jacket of claim 6 , wherein the first coolant channel is in fluid communication with the second coolant channel for permitting fluid coolant on the rear section of the bowl sheet to cross from the rear section of the bowl sheet to the front section of the bowl sheet.
9. The cooling jacket of claim 6 , wherein the cooling jacket is constructed from metal components that have been welded together, and wherein the welds between the components are lap welds.
