Abstract
Disclosed are a method and apparatus for chilling food product, employing(A) cooling means comprising (1) a rotatable drum, (2) means in said drum for urging pieces through said drum, (3) cryogen dispensing means, and (4) means for rotating said drum;(B) feeding means which includes means for automatically sensing the mass flow rate at which said pieces are being fed into said inlet and for generating electrical signals corresponding to said rate;(C) electronic control means responsive to said signals and temperature inputs for preventing premature flow of cryogen and for automatically controlling the rate at which cryogen is fed so as to lower the temperature of said pieces to the desired exit temperature.
