A novel self-cooling food product container apparatus (10) and a process for manufacturing the same is disclosed. A self-cooling food product container (20) combined with a substantive vapor transport system producing a humidification cooling process for cooling food and beverage products P. Methods of assembling and operating the apparatus (10) are also provided.

A galley cooler is disclosed herein. The galley cooler includes a cooling system and an atomizer system. The cooling system includes a hot side and a cold side. The hot side includes a hot side inlet. The cold side is configured to, in response to cooling internal galley air entering the cooling system, condense moist air into liquid water on the cold side thereby forming condensate. The atomizer system is configured to, responsive to receiving the condensate, atomize the condensate into an atomized mist that is projected into the ambient air.

A defrosting system includes a freezer body and a dehumidification device with a desiccant rotor. The desiccant rotor includes a treatment region and a regeneration region. The dehumidification device is configured to reduce moisture in the freezer body and removes frost in the freezer body by means of the desiccant rotor. The dehumidification device includes a treatment air inlet and a treatment air outlet. The treatment air inlet is configured to draw to-be-treated air out of the freezer body. The treatment air outlet is configured to transport dry air, dehumidified by adsorption of the desiccant rotor, back into the freezer body. By adopting the defrosting system for a freezer, no condensate water is produced in the whole dehumidification process of the freezer, and no water needs to be drained out of the freezer.
