<p>A chiller (1) suitable for chilling shoes in manufacture. The chiller includes a refrigeration system (2) having two evaporators (25, 30) which are operated alternately to allow each evaporator (25, 30) to be defrosted whilst the other provides a chilling function to an airflow through the chiller (1), alternation between the evaporators (25, 30) being through suitable valve switch mechanisms (27, 28) and preferably such that there is a degree of chilling duty cycle overlap to ensure consistent cooling of the airflow. Furthermore, in the chiller airflow direction means suction paddles (34, 35) are provided to ensure differing paths through the chiller including respective evaporator elements (25, 30).</p> |
