Abstract (en)
[origin: US4457142A] A chilling container includes a chilling agent chamber and a chilled goods chamber. The chilling agent chamber is sealed shut to contain e.g. dry ice, is highly insulated from the outside, and is connected by a pressure passage system to the chilled goods chamber which has an opening to the outside and a door. The chilling agent is vaporized in the chilling agent chamber by removal of the heat. A pressure drop occurs and therewith a forced movement with a forced circulation of the vaporized gases into the chilled goods chamber. A wall containing the pressure passage system is cooler and is opposite the door causing convection circulation which reinforces the forced circulation. A wall separating the chambers is relatively highly heat conductive.
