A cooling device which includes a conveyer belt to carry food products thereinto is provided with improvements in which a spraying device for spraying a cold salt solution onto the belt includes a first and second spraying unit provided above and below the conveyer belt so that a salt solution can be sprayed both directly onto the food products and onto the bottom side of the belt when the food products are covered or packaged, or sprayed onto the bottom side of the belt only when the food products are not covered or packaged. A secondary cooling unit operating with a cooling medium coming from an evaporator of the cooling device includes a tray-like member divided by a heat transfer plate into an upper chamber for receiving the salt solution after being sprayed and a lower chamber for receiving the cooling medium.
