Abstract
A temperature controlled dough mixer having a bowl which is provided with a cooled sheet panel, a pair of cooled end panels and a cooled breaker tube extending between the end panels. A cooled agitator may be rotatably mounted between the end panels of the bowl. Cooling of the sheet panel is effected by a series of internal, side-by-side flow channels which are interconnected at alternate ends to define a plurality of segregated serpentine flow paths for an appropriate cooling fluid. The mixer also includes temperature sensing means for sensing the temperature within the bowl and control means responsive to the temperature sensing means for controlling the flow of cooling fluid through the cooled portions of the mixer.
Claims12
In a dough mixer comprising a tilting open top bowl, an agitator mounted within said bowl and means for providing a supply of cooling fluid to said bowl;
- said bowl comprising a sheet panel curved about an axis lying within said bowl, a pair of end panels joined to said sheet panel for closing out the ends of said bowl, and means within said sheet panel defining a series of side-by-side flow channels which extend between said end panels and which are interconnected at alternate ends for creation of a generally serpentine flow path for said cooling fluid;
- the improvement wherein a hollow breaker tube extends between said end panels and wherein said channel defining means define a plurality of segregated serpentine flow paths, each having inlet and outlet ports connected for separately circulating said cooling fluid and cooperatively cooling substantially the entire interior surface of said sheet panel;
- the interior of said breaker tube being connected in series with one of said serpentine flow paths so that said cooling fluid circulates therethrough and cools said breaker tube.
A refrigerated dough mixer comprising an open top bowl including a curved sheet panel and a pair of parallel end panels disposed at opposite ends of said sheet panel, means for providing a supply of cooling fluid to said bowl, an agitator extending between said end panels and journaled for rotation within said bowl, a hollow breaker tube extending between said end panels, a hollow dough retarding tube extending between said end panels, means within said sheet panel defining a series of side-by-side flow channels which extend between said end panels and which are interconnected for circulating said cooling fluid and cooperatively cooling substantially the entire interior surface of said sheet panel, means defining fluid flow channels within said end panels for circulating said cooling fluid and cooperatively cooling substantially the entire interior surface of said end panels, means causing said cooling fluid to be circulated through said breaker tube and said dough retarding tube, temperature sensing means for sensing the temperature within said bowl, and control means responsive to said temperature sensing means for controlling the flow of said cooling fluid.
