摘要：
The installation comprises a table having a lower face and an upper face on which the product to be crusted extends, a unit (1, 4) for injecting a cryogenic liquid such as liquid nitrogen in an interior of the table, a unit (2) for evacuating the gas resulting from the vaporization of cryogen, a unit (6) for regulating a temperature of a surface of the upper face of table, and a data processing unit for restoring a value of temperature of gas at a setpoint. An interior of the table is equipped with a baffle structure (3) within which the cryogen circulates. The installation comprises a table having a lower face and an upper face on which the product to be crusted extends, a unit (1, 4) for injecting a cryogenic liquid such as liquid nitrogen in an interior of the table, a unit (2) for evacuating the gas resulting from the vaporization of cryogen, a unit (6) for regulating a temperature of a surface of the upper face of table, and a data processing unit for restoring a value of temperature of gas at a setpoint. An interior of the table is equipped with a baffle structure (3) within which the cryogen circulates, where the structure is provided between an inlet and an outlet of the table. The regulation unit comprises a unit (5) for measuring the temperature of gas outcoming from the table. An independent claim is included for a process for cryogenically cooling or deep-freezing a product.L'invention concerne un procédé et une installation de refroidissement ou surgélation cryogénique de produits, visant à réaliser le croutage d'au moins une des surfaces du produit par la mise en contact de cette surface du produit avec la surface d'un support refroidi se caractérisant par la mise en œuvre des mesures suivantes : - l'installation comprend une table (T) présentant une face inférieure et une face supérieure, face supérieure sur laquelle va s'effectuer le croutage des produits ； - l'installation comprend des moyens (4, 1) d'injection d'un cryogène, par exemple d'azote liq
