ABSTRACT:
The invention provides a method and apparatus for preparing frozen free-flowing particles of food product. Particles of solid food are supplied, or viscous food material is extruded, or liquid or semi-liquid food material is pumped through apertures, to a freezing stage. In the freezing stage, cryogenic substance is used to freeze the food material to a temperature at which the material is frangible. The frangible food material passes to a fracturing stage such as a fracturing mill, which produces frozen food particles of a size small enough to pass through discharge apertures of the fracturing stage. The discharged particles are screened to remove undersized particles which are recycled, the remaining frozen particles being generally within a defined size range and constituting the final product.
