Abstract:
A plant for continuous flow freezing of items which are introduced into an enclosed freezing section while on a driven tray conveyor which includes an inner area, comprising:a conveyor chain which is guided on a side by driving elements in a vertically upwards or a vertically downwards direction in a spiral-like manner and which is led upwardly and downwardly in the freezing section from an inlet to an outlet of the freezing plant; a means for freezing air circulating in the freezing section which includes at least one freezing aggregate and at least one associated freezing-air circulation blower or fan for maintaining a flow of freezing air passing around and across the items to be frozen while the items are transported on the tray conveyor; and at least two frames in the freezing section, wherein the at least two frames are positioned adjacent each other and arranged within the inner area of the tray conveyor and wherein each of the at least two frames have an inner area and an outer area and support the tray conveyor on the outer area of the at least two frames, wherein each of the at least two frames have a passage for freezing air between the inner area and the outer area of each of the at least two frames, and wherein the inner area of at least one of the frames supports within the inner area of the frame the at least one cooling aggregate and the inner area of the at least one of the frames supports within the inner area of the frame the at least one fan or blower for guiding the flow of the freezing air through the at least one cooling aggregate, through the outer area of the at least two frames and through the tray conveyor with items to be frozen lying thereon.
