Abstract
A continuous transfer type freezer for cooling or freezing articles such as foodstuffs transferred on a conveyor belt by spraying chilled air from slit nozzles on the articles is provided in which chilled air jets rectified to have long spray travel is produced, thin stream layer of chilled air is formed on the surface of the article to achieve increased heat transfer, and exhaust passages of the chilled air are formed such that they do not affect the cooling function. A plurality of slit nozzlesare apposed above and under the conveyor belt along the belt transfer direction, each of the nozzlesis shaped such that it has an angled and succeeding parallel entrance way so that the chilled air is rectified in the entrance ways and spout from the nozzle opening at large velocity, and exhaust passagesare formed between each of the slit nozzles such that the chilled air spouted from the nozzles flows toward both lateral end sides of the conveyor belt
