A system for cooling comestibles is provided in multiple tiers of relatively shallow trays or receptacles vertically spaced apart at close intervals and mounted in a rack, in combination with one or more hollow wands containing refrigerant. Each wand is configured to have a longitudinally grooved immersible section which is insertible through narrow spaces between trays into material to be chilled. A reservoir for refrigerant extends from one end of the wand to the other. The wand can be periodically or continuously manipulated in twirling, revolving and translating motions which simultaneously mix the food and agitate the refrigerant so that the refrigerant circulates within the interior of the wand and quickly cools the food.
