Cryogenic freezer with a liquid trap |
摘要 |
A trap or seal system for effecting an air impervious seal for a food freezer, such as a cryogenic or mechanical freezer. The seal system includes a barrier forming a vapor-impervious partition and which has its bottom extending into a cryogenic bath. A conveyor system is used to transport articles through the cryogenic bath to a downstream cryogenic freezer. The combination of the barrier extending into the cryogenic bath forms an effective seal to prevent air infiltration into the cryogenic freezer.
