Abstract

A loaf of bread is frozen by slicing the loaf, separating the slices, freezing the slices with liquid nitrogen, and collating the frozen slices to reform the loaf. As illustrated, the loaf is sliced by passage through fixed blades 13 and the slices are separated by tapered blades 14 before passage through a freezer 15. The freezer comprises hollow plates 22 connected to a liquid nitrogen header 20, the plates being perforated so that slices passing between the plates are sprayed with the nitrogen. The frozen slices pass between tapered blades 16 so that the article is reformed on a conveyer 12. The article is compacted against a gate 26 which is then lifted to allow the article to pass on to wrapping and packing steps. Vaporized nitrogen from the freezer may be used to precool the slices. In other embodiments, not shown, the slices may be separated by moving one set of alternate slices relative to the remaining set to form two horizontally or vertically spaced ranks.
