ABSTRACT:
DESCRIPTION
The invention relates to a new method in fish processing for best possible protection of fish fillets through the whole processing, from filleting (deskinning) to packing or/and freezing.
Tray processing lines have been widely used. The character of tray processing lines are buffer of fillets ca. 15-20 kg pr. tray and the trays are handled or conveyed from one workplace to another until processing is finished. Disadvantage relates to the quantity pr. tray 15-20 kg (approx. 30-60 fillets) causing bad handling of fillets and a long waiting time between operations, leading to drip loss and poor quality.
Flow lines have been the most used method recently and with its increased speed of fillets throughout the process, the processing time has decreased and also the drip loss. The disadvantage of the flow lines is bad handling of individual fillets or fillet parts by dropping from one conveyor belt to another and series of pushes by air operated cylinders of fillets from conveyor belt to buffers. This handling cause poor utilisation of the fillets and fillet portions for the most valuable products.
The present invention is a new method for gentle handling of fillet or fillet portions through the entire process by placing fillets on a plate. The plates are conveyed between operations. Only at the trimming-table and and inspection-table fillets or fillet parts are moved from the plate for trimming or quality control, Every plate has its own identifier I.D (chips or bar code) for identifying where it is situated in the process for internal control.
