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 precooling with 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) a sorting 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 saving the production cost.
Description
Technical field
The present invention relates to a kind of trawler processing technology, specifically be meant a kind of vertical flat plate processing technology based on large-scale distant-water trawler.
Background technology
At present, the large-scale distant-water trawler that China enterprise adopts all is the external second-hand large-scale trawler of buying, and is the type of eliminating the edge abroad basically, and processing factory wherein adopts relatively backward processing technology.This class processing factory adopts horizontal flat board, therefore needs a large amount of operating personnel and participate in process, and not only production efficiency is not high, and is also wasting great amount of manpower and material resources virtually.Simultaneously, in the refrigeration system flow process, fish mostly all not through this key link of ice slurry precooling, therefore makes that fish temperature before material loading is higher before freezing, just prolonged the whole freezing period time virtually, is unfavorable for saving cost.
Summary of the invention
It is not high to the objective of the invention is to overcome present large-scale trawler production efficiency, and the defective that freeze cycle is long provides a kind of simple in structure, efficient is higher, freeze cycle is short vertical flat plate processing technology based on large-scale distant-water trawler.
Purpose of the present invention is achieved through the following technical solutions: the vertical flat plate processing technology based on large-scale distant-water trawler, it is characterized in that, and mainly may further comprise the steps:
(a) fish of salvaging is sent to fish box and carried out seawater cleaning and one-level precooling, and undertaken after the vacuum suction first time is handled this fish being sent into RSW (Refrigerated Sea Water Tanks, freezing sea water tank) by vacuum fish-pumping system and carry out the precooling of Mare Frigoris water secondary;
(b) carry out the vacuum suction second time and handle carrying out fish after the precooling of Mare Frigoris water secondary by vacuum fish-pumping system, and the fish after will handling is sent into hopper;
(c) fish in the hopper is sent into the fish jar and ices three grades of precoolings of slurry after sorter letter sorting;
(d) fish after the precooling being sent into the vertical flat plate system by conveyer carries out finally freezing;
(e) fish that freezes is sent into bagging area is packed, coding, and be transported to the cargo hold refrigerating chamber by lift or conveyer belt and store.
In order better to realize the present invention, when the fish described in the step (c) in the hopper is sent into the fish jar after the sorter letter sorting, be transported in the different fish jars by the fish of sorter with different size.
Simultaneously, the pre-cool time of one-level described in the step (a) is between 1～6 hour, and the pre-cool time of described secondary is between 12～36 hours.
The present invention compares than prior art, has the following advantages and beneficial effect:
(1) processing factory of the present invention adopts vertical flat plate, can realize the automation of material loading, has not only reduced the operating personnel on the production line in a large number, and has reduced the time of whole freezing period, thereby improved production efficiency, has saved production cost.
(2) the present invention carries out final also having carried out three grades of precoolings of ice slurry before freezing the fish in the fish jar being sent into the vertical flat plate system, thereby has effectively reduced the time of whole freezing period, has improved production efficiency, has saved production cost.
Description of drawings
Fig. 1 is a schematic flow sheet of the present invention.
The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, technological process of the present invention is: (a) earlier the fish of salvaging is sent to fish box by trawler and carried out seawater cleaning and one-level precooling, and undertaken after the vacuum suction first time is handled this fish being sent into RSW by vacuum fish-pumping system and carry out the precooling of Mare Frigoris water secondary.Wherein, so-called secondary precooling be meant one the cover independent refrigeration system cooling is carried out in this zone, the one-level precooling then is the backwater after the secondary precooling, water temperature is than the water temperature height of secondary precooling.In order to realize the present invention preferably, the pre-cool time of first order precooling is 1～6 hour, and the pre-cool time of second level precooling is 12～36 hours.
(b) carry out the vacuum suction second time and handle carrying out fish after the precooling of Mare Frigoris water secondary by vacuum fish-pumping system, and the fish after will handling is sent into hopper.
(c) fish in the hopper is sent into different fish jars by the specification difference after the sorter letter sorting and ice three grades of precoolings of slurry.Three grades of chilldown systems of so-called ice slurry belong to independently system, adopt a cover ice pulp grinder to be used for producing the ice slurry, the ice slurry that to produce then is piped to fish jar and inner sea water mixing, form the low temperature environment of an ice slurry and sea water mixing, make fish immerse this environment inside, make it promptly fast good again cooling.
(d) fish after the precooling being sent into the vertical flat plate system carries out finally freezing.Accordingly, final need that also the fish after the precooling is carried out material loading before freezing and handle carrying out.
(e) fish that freezes is sent into bagging area is packed, coding, and be transported to the cargo hold refrigerating chamber by lift or conveyer belt and store.
In order to reach effect preferably, processing factory of the present invention has integrated 36 vertical flat plate equipment, has gathered a complete set of high-power vacuum fish-pumping equipment, therefore can make fish body damage ratio be lower than 5/10000ths.
As mentioned above, just can well realize the present invention.
