ABSTRACT:
A self-service low temperature cooling cabinet for easily spoilable food and/or edible products, especially ice cream, with an easily accessible front withdrawing opening and two cooling units or groups of cooling units comprising a ventilator and an evaporator. These cooling units or groups of cooling units convey the cooling air in a circuit over the goods to be cooled and subsequently again to the evaporators of the cooling units or group of cooling units. Above and below a display chamber confined by the withdrawing opening and a servicing opening as well as by a closed air impermeable bottom and ceiling wall there is respectively provided an evaporator cell having respectively associated therewith an evaporator or a group of evaporators. Within the region of the withdrawal opening and the servicing opening, the evaporator cells are provided with at least partially aligned air inlet and outlet openings in such a way that the cooling air current in the vicinity of one end of the display chamber designed as freezing chamber is divided in such a way that one portion of the cooling air current serves for freezing the food and/or edible products whereas another portion of the cooling air current serves for creating a cooling barrier at the withdrawal opening, both portions of the cooling air current reuniting in the vicinity of the other end of the display cabinet.
