Processing in line boats / Processing in line boats

This project is a collaborative project of the following companies; Matís ohf, Brim hf, Samherji hf, Vísir hf, Hraðfrystihúsið Gunnvör hf and 3X Technology. The aim of the project is to improve the processing processes of longline vessels with a view to reducing the cost of processing, increasing work efficiency and product quality. The result of this report is: Design of a production process on board liner vessels, a result report. Experimental report on thawing of bait, saury, condoms and herring. And a preliminary draft for the design of an automatic train system on board a liner. The main results of the project are the following: Great optimization involves thawing the bait in so-called snail tanks, the thawing time will be reduced from 17 hours to about 2-3 hours. Instead of taking the bait out 17 hours earlier, it is fed directly into the thawing tank from the bait freezer. This method saves a lot of time. Experiments show that fish that are allowed to bleed for approx. 10-15 minutes during a large water change, are then gutted and then cooled down to zero degrees for approx. A special processing process was designed on board liners that addresses these quality stamps. A preliminary draft of an automatic train system on board future liner vessels was also designed. The purpose of such a system is to have no train attendant on board the train, but to arrange and sort it on top of the working deck in the trolleys. The tub then goes into a specially designed tub lift, which was also designed for this project, onto the train and onto special train straps that move the tub to the relevant place on the train.

This project is a collaboration work between; Matis ohf, Brim hf, Samherji hf, Vísir hf, Hradfrystihusið Gunnvör hf and 3X Technology. The object of this project is to improve the process in line boats by reducing production costs, improve working conditions and product quality. The projects payoff is; Design of processing line onboard line boats, payoff report. Experiment report on thawing of bait, Saury, Cuttle and Herring. Also preliminary design of automatic system for loading boxes from holds in line boats. The primary results from this report are as follows: A great increase in efficiency is by thawing the bait in so called screw tanks, the thawing time reduced from 17 hours (current thawing method) down to appr. 2 - 3 hours. Instead of taking the bait out of the freezer 17 hours before use, the screw tank is feed from the freezer simultaneously. Previous experiments show that when the fish is bleeded for appr. 10‐15 minutes, and then gutted and afterwards cooled down to zero degree on Celsius for approx. 20-25 minutes in a special screw tank filled with slush gives increased fish quality. A special processing trail was designed for lineboats which takes into account this quality.
