Vertical plate processing technique based on large-scale long distance trawler

Abstract

The invention discloses a vertical plate processing technique based on a large-scale long distance trawler, which is characterized by mainly comprising the following steps: (a) caught fish is sent into a fish box to carry out sea water cleaning and primary precooling, a fish vacuumizing system vacuumizes fish for the first time, and the fish is sent to an RSW to carry out the secondary precoolingwith cold sea water; (b) the fish vacuumizing system vacuumizes the fish, which is secondarily precooled by cold sea water, for the second time, and sends the processed fish into a fish hopper; (c) asorting machine sorts the fish in the fish hopper and sends the fish into a fish tank to be tertiarily precooled with ice slurry; (d) a conveyer sends the precooled fish into a vertical plate system to be finally frozen; and (e) the frozen fish is sent into a packaging area for packaging and spraying codes, and an elevator or conveyer belt conveys the fish to a freight cabin freezing chamber to be stored. The invention greatly reduces the operating personnel on the production line and shortens the time length of the whole freezing period, thereby enhancing the production efficiency and savingthe production cost.

Description

technical field [0001] The invention relates to a fishing trawler processing technology, in particular to a vertical plate processing technology based on a large ocean-going trawler. Background technique [0002] At present, the large ocean-going trawlers used by Chinese enterprises are all second-hand foreign large-scale trawlers purchased, which are basically the types that are on the verge of being eliminated abroad, and the processing plants in them also use relatively backward processing technology. This type of processing plant basically uses horizontal flat plates, so a large number of operators are required to participate in the processing process, not only the production efficiency is not high, but also a lot of manpower and material resources are wasted virtually. At the same time, in the freezing system process, most of the fish have not been pre-cooled by ice slurry before freezing, so the temperature of the fish is higher before feeding, which virtually prolongs...
