Abstract
A cooling apparatus for an extruder includes a supply line configured to receive bulk coolant from a supply circuit via an inlet. The supply line delivers supply coolant to the extruder along a flow path. A return line communicates expelled coolant from the extruder, and a circulation line connects the supply line to the return line. The circulation line supplies a recirculated portion of the expelled coolant to the supply line and mixes the bulk coolant with the recirculated portion of the expelled coolant forming the supply coolant. A bypass line connects the supply line to the return line, and a flow control valve connects one of the supply line and the return line to the bypass line. A proportion of the expelled coolant to the bulk coolant forming the supply coolant is adjusted by the flow control valve to control the temperature of the supply coolant.
