Abstract
A freezer for a liquid in a receptacle (14) comprises a housing (1), containing a cooling battery (5) for cooling a gas, a means (7) for generating a flow of the cooled gas and a jet device. The latter comprises a plurality of shells (6), each completely surrounding a receptacle (14) inserted into the respective shells with the exception of a first opening (15) for inserting the receptacle and a second opening (16) for discharging a flow of gas resulting from jets directed towards the outside of the receptacle. Each shell (6) has holes (18) in all its side walls in areas directly opposite a receptacle inserted into the shell for directing jets towards the outside of the receptacle. In addition, the freezer has indicators (11) for indicating which shells (6) do not contain a receptacle (14) and for indicating when the liquid in a receptacle inserted into a shell is frozen.
