Abstract: The apparatus or “chiller” uses an upward stream of ambient air drawn through the upright housing to cool crumb rubber particles that are deposited into and fall through the housing. The chiller includes an upright chiller housing and an array of internal baffles disposed within the lower section of the housing. Crumb rubber deposited into the chiller housing falls through the upward air flow within the chiller housing and cascades around and through the baffle array before exiting the chiller.

The baffle array also creates a more turbulent air flow through which the crumb rubber falls. The rising turbulent air mass enhances the transfer of thermal energy from the falling crumb rubber.
