ABSTRACT:
A freezer (1) which comprises a drum (2) is characterized in that a cylinder (12) is disposed in said drum (2), and a fan (14) is provided for circulating cryogen through the space (20) between the outer surface of the cylinder (12) and the inner surface of the drum (2). The outer surface of the drum (2) is provided with a plurality of grooves (4) of parabolic cross-section. In use, droplets (23) of liquid egg are dropped on to the grooves (4) where they freeze individually. The frozen particles fall away from the drum as they approach the lowermost point of travel of the drum (2) and form an attractive granular product.
