| 摘要 |
The invention consists of a method for increasing efficiency in the freezing of delicate items of food in freezing tunnels of the conventional type, consisting of a freezing tunnel (8) having means (6 and 7 ) for providing a strongly cooled flow of air to act as a freezing agent, at least two or more endless freezing conveyor belts (2, 3, 4) and (5 ) supported therein, a movable feeding conveyor (1) and a transfer conveyor (9), where said items of food do not tolerate being dropped from th e upper freezing conveyors (2, 3, 4) onto the bottom freezing conveyor (5) until they have gained sufficient stiffness to preserve their undeformed shape; said method consisting of placing delicate items of food on the upper freezing conveyors (2, 3, 4), one at a time by means of the moveable feeding conveyor (1), where the said upper freezing conveyors are stopped in a fixed sequence.
