Available in capacities between 200 and 240 cubic feet, the Dupps Batch Cooker (shown right) is ideal for heavy duty applications like blood drying and hydrolyzing. The toughest and most rugged herringbone gear reducer drive available provides trouble-free processing under the heaviest loads. A strong, easy-access underframe simplifies piping and cleaning. Overlapping agitator arms are pitched forward to move material continuously toward the discharge end of the cooker and assure thorough agitation. A special arm is used for feather processing. For certain applications up to 300 cubic feet, Dupps offers the proven Douglas Rownson Batch Cooker (shown left). Its unique design features steam flow within the agitator and a large heating surface area to achieve maximum operating efficiency, faster processing and minimal steam consumption. Batch Cookers are supplied complete with motor and drive assembly mounted on a rugged underframe.
