ABSTRACT:
A generally rectangular container is provided including insulated top, bottom, opposite side and opposite end walls. An upstanding transverse insulated hollow housing is mounted within the container adjacent one end thereof and a CO.sub.2 snow cabinet constructed of good heat transfer material is disposed within the housing with opposing wall portions of the cabinet and housing passing exteriorly about the cabinet. A heat insulative horizontal baffle is mounted within the container spaced below the top wall and extends between the sidewalls thereof. The baffle defines a cooled air passage beneath the top wall extending lengthwise of the container. The airflow passage includes an outlet end adjacent and in at least reasonably closed communication with the end of the cooled air passage adjacent the aforementioned one container end wall and an inlet end opening outwardly of the housing into the interior of the container below the baffle. The end of the cooled air passage adjacent the other container end wall opens into the interior of the container and thermostatically controllable air pump structure is provided to effect airflow inwardly of the inlet of the airflow passage, through the airflow passage and into the cooled air passage. Further, structure is provided for spray discharging of liquid CO.sub.2 into the interior of the upper portion of the cabinet and into the airflow passage at points spaced therealong in order to form CO.sub.2 snow therein.
