Patent pending pinbone concepts
The invention is targeting to solve a puzzle, which has until now remained unsolved. Conventional methods have over numerous attempts proven to be unsuccessful on especially fresh fish fillets. The removal of the pinbones is a critical part of procesing fresh fish, where present technology has of yet not achieved noticeable success on pre-rigor filets no matter the specie. The result if successful will change the markets substantially. Distribution chains and processing plants will change in order to finish the products as close to live state as possible. This again will bring fresh and firmer fish products to market, with significant impact on price and quality on white fish as well as salmonids and other species.
IT IS IMPORTANT TO UNDERLINE, THAT OUR SOLUTIONS ARE BASED ON ALREADY AVAILABLE TECHNOLOGIES AND THEREFORE CONTAIN A REALISTIC DEVELOPMENT SCENARIO. THE AIM IS TO PROVIDE INVESTORS WITH A CLEAR DIRECTION AND READY TO WORK PROJECT.
With today’s technology it can be done in following ways:
- Manually, where operators have small tools to pick the bones from the flesh (figure 1)
- Semi-automatic, where a handheld rotating shredded drum is positioned to rip the bones from the flesh (figure 2)
- Automatic, where a conveyor takes the fish through one or more rotating drums (figure 3)
- High speed, but where fillets have to be divided from 2 to 6 lanes due to the line speed, and merged from 6 to 2 lines after pinbone removal.
The speed of today’s filleting machines calls for 6 lanes (fig 4), which demands significant space lengthwise as in width. It is expensive, not easy to maintain or clean, while also posing one of the most serious bacteria hazards in a factory. In addition, the above methods have not worked properly on fresh (pre-rigor) fish fillets, where the firm flesh and bone fastens to the skin make this impossible without damaging the flesh.
