Cooling or freezing apparatus

A cooling or freezing apparatus comprising

• a housing containing means of transport for moving, in a vertical direction, carriers for goods to be cooled or frozen in the apparatus, the carriers stacked one above the other,
• the means of transport being arranged at the bottom of the housing and comprising two transport devices, each of which includes a plurality of mutually parallel support rails connected to a shaft by bracket means extending eccentrically with respect to the axis of the shaft, the shaft extending centrally with respect to the corresponding support rails, said support rails being arranged as generatrices of an imaginary cylinder and being rotatable about the axis of the cylinder,
• the two transport devices being arranged along the sides of the housing opposite each other and connected to drive means for rotating the oppositely arranged transport devices about the axes thereof in mutually opposite directions,
• each of the carriers for the goods being provided with spacer means along the sides of the carriers, the height of the spacer means corresponding to the distance in the vertical direction between two adjacent support rails of a transport device after rotation of the transport device an angle corresponding to the pitch of the support rails from a position in which the two adjacent support rails are positioned vertically above each other,
• each of said carriers also being provided with laterally extending flap means for engagement with said support rails, the spacing of said flap means in the vertical direction and in the stacked position of the carriers corresponding to the height of said spacer means, said flap means moreover having a length corresponding to the distance in the horizontal direction between two adjacent support rails in the position which such two adjacent support rails occupy after having been rotated one pitch from the position in which such two adjacent support rails are positioned vertically above each other.
