Abstract

To improve the thermal transmission during freezing processes it is proposed that the goods to be cooled and a pre-cooled body of high thermal capacity be pressed against each other.Improved thermal transmission is also attained with a device comprising a holding device which during the cooling process holds the goods to be cooled essentially in a non-deformable way, allowing direct contact between the coolant and the goods to be cooled. Preferably, vertically aligned channels are arranged between the holding device and the goods to be cooled, with coolant flowing in said channels.
