Frost prevention device for feeding and discharging port of automatic plasma refrigeration house

The utility model belongs to the technical field of refrigeration houses, and particularly relates to a built-in detachable frost prevention device of an automatic plasma refrigeration house, which comprises a frost prevention folded plate, the cross section of the frost prevention folded plate is inverted U-shaped, and the frost prevention folded plate is positioned on the inner side of the material inlet and outlet of the refrigeration house. The frost prevention folded plate and the cargo tray at the lower end of the feeding and discharging port define a frost prevention device. The detachable and replaceable frost prevention device arranged in the automatic refrigeration storage solves the problem that hot and humid air outside the refrigeration storage enters the lowest-temperature air cooler in the refrigeration storage to be frozen and frosted, and avoids the problems that normal operation of the air cooler is affected and refrigeration cannot be conducted by the hot and humid air. 本实用新型属于冷库技术领域，尤其涉及一种
