A The Application of Thermo-physical Properties of Foods Adhesion in Frozen Foods Sizing Cryogenic Tunnel Freezers

A Overcoming Adhesion The Problems Product damage Wasted energy – Heat required to release the product – Extra refrigeration required to re-cool the moulds Treatment of the thawed waste

A Mould Surface Temperature ( o C) Shear Strength (kg/cm2) Adhesion increases as temperature falls Product fractures internally because surface bond is stronger Adhesion reduces to zero as temperature falls Temperature Adhesion Profile

AConventional Mould Surface Magnified Detail at ContactProduct Freeze Surface Ice crystallisation starts in the crevices and grows into the product... … which is keyed and strongly adhered to the mould surface. Conventional Surface Freezing Effect

A Cryo-ZAT Mould Surface below -80 o C Magnified Detail at Contact Product freezes in its bulk and does not fully wet the mould surface... … and the differential contraction between product and mould breaks any bonding ZAT Surface Freezing Effect

A Cryo-ZAT TM offers the Ice Cream Buyer... High definition surface detail Exciting and Novel 3-Dimensional shapes Cryogenic freeze quality giving superior texture and Mouthfeel
