Description
Technical field
The present invention relates to seawater seawater fishery processing technique field, and in particular to a kind of marine processing method of tuna and gold
Marlin system of processing.
Background technology
Tuna is a kind of large-scale pelagic important goods food fish, and nutritive value is high, the tender deliciousness of meat, and not by
Environmental pollution.At present, the tuna supply of China it is main by ocean from catch with trade import two ways, the former is due to China
Marine site is vast, and operating location leaves port city farther out, and the fishing of operation ship is reached behind harbour, and tuna quality is difficult to ensure that；
The latter's financial cost is high, has quarantine risk.
The existing chilled process of tuna mainly using ice from fish mouth toward alvus in fill in, fill up it is real, in fish layer and fish layer
Between by least 30 centimetres ice sheets, such a chilled method is easily caused product and enters behind storehouse to need to wait full storehouse to start shooting again cooling, shadow
Ring product quality.How the problem of prior art is present is solved, it has also become this area practitioner needs technical research and technology badly
The problem of implementation.
The content of the invention
The present invention is realizes object above, using following scheme：A kind of marine processing method of tuna, this method is included such as
Lower step：
(a) pre-process：The tuna fished for is subjected to prune job on dredger；
(b) unloading is handled：Dry and cold room is put into pretreated tuna fresh-keeping, and is transported to factory-mothership, when fresh-keeping
Between be 2-3 hours；
(c) roughing：Step (b) the dry and cold fresh-keeping tuna is transported to factory-mothership, to fish body carry out crop,
Solution plane；
(d) finish：Tuna fish body after step (c) roughing is cut into slices, it is divided rank, refrigeration, true
Empty package, refrigerated storage temperature is -10 DEG C；
(e) it is quick-frozen：Step (d) the vacuum-packed tuna piece is subjected to quick-frozen, extremely -60 DEG C of quick freezing temperature, it is quick-frozen
Time is 3-6 hours, is taken out, and is packed, refrigeration, and refrigerated storage temperature is 0-2 DEG C；
It is preferred that, in the step (a) prune job include carrying out the tuna of capture bloodletting, back-end crop, remove the internal organs,
Rinse, hang upside down and bleed.
Preferably, dry and cold room preservation temperature is -2 DEG C -1 DEG C in the step (b).
Preferably, cold preservation time is 1-2 hours in the step (d).
The invention discloses a kind of marine processing method of tuna and tuna system of processing, table is used by repetition test
It is bright compared with prior art, with some following beneficial effect：
1. the marine processing method of tuna have step it is few, it is easy implement, by the treatment by stages to fish body, realize fish
The meat of body is fresh-keeping, it is to avoid its mouthfeel brought because being pyrolyzed after freezing is lost in.
2. fish body cold preservation time is short, by the way that by fish body quick freezing temperature, to -60 DEG C, the quick-frozen time is 3-6 hours, you can realized
Required preserve requires.
3. a tuna system of processing is simple in construction, easy to use, cost is low, the quality of item after processing is high.
4. the fishing boat specification used in system of processing is small, be easy to fishing boat to be managed collectively, great amount of fuel oil and time wave are solved
The problem of taking in distance.
Brief description of the drawings
Fig. 1 is a kind of marine system of processing structural representation of tuna of the present invention.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, and reference
The present invention is described in more detail for accompanying drawing.
A kind of marine processing method of tuna is provided in an embodiment of the present invention, is comprised the following steps：
(a) pre-process：The tuna fished for is subjected to prune job on dredger；
(b) unloading is handled：Dry and cold room is put into pretreated tuna fresh-keeping, and is transported to factory-mothership, when fresh-keeping
Between be 2-3 hours；
(c) roughing：Step (b) the dry and cold fresh-keeping tuna is transported to factory-mothership, to fish body carry out crop,
Solution plane；
(d) finish：Tuna fish body after step (c) roughing is cut into slices, it is divided rank, refrigeration, true
Empty package, refrigerated storage temperature is -10 DEG C；
(e) it is quick-frozen：Step (d) the vacuum-packed tuna piece is subjected to quick-frozen, extremely -60 DEG C of quick freezing temperature, it is quick-frozen
Time is 3-6 hours, is taken out, and is packed, refrigeration, and refrigerated storage temperature is 0-2 DEG C；
The present invention its compared with tuna processing method of the prior art, form a whole set of complete technological process pair
Tuna carries out freeze cutting, technical maturity and integrated level height, has saved human cost, has reduced manual operation, has greatly improved
Operating efficiency and use mouthfeel.
It is preferred that, in the step (a) prune job include carrying out the tuna of capture bloodletting, back-end crop, remove the internal organs,
Rinse, it is projecting bleed, be effectively prevented from extravasated blood in tuna body, thus avoid because blood stasis influence flesh of fish quality, outward appearance, mouthfeel with
And slow down rates of spoilage.
Preferably, dry and cold room preservation temperature is -2 DEG C -1 DEG C in the step (b), within the time period can guarantee fund's rifle
Fish fish matter.
Preferably, cold preservation time is 1-2 hours in the step (d), it is to avoid tuna fillet excessively chill.
The embodiment of the present invention additionally provides a kind of tuna sea processing system using the marine processing method of foregoing tuna
System, as shown in drawings, including several dredgers worked including lash ship and around lash ship；

Manage between device and flesh of fish refrigerating plant；
The flesh of fish refrigerating plant includes connecting fixed after single-freeze slicer, timing quick-freezing plant, the single-freeze slicer
When quick-freezing plant.
Preferably, the dredger includes dry and cold provided with least one in trawler, purse seiner, longliner, its nacelle
Fresh-keeping storehouse, it is dry and cold fresh-keeping for being carried out to the tuna captured.
The whole workflow of tuna sea system of processing is as follows：, dredger is captured after tuna, by using metal tip
The hindbrain nervi vertebralis of pin puncture tuna, makes its neural death, keeps the life state of heart and human body, is then put successively
Blood；Remove internal organ and the gill：Make that product perception is good, rinse well：Clean, then taken a shower with seawater from afterbody to head, it is ensured that product
Quality；It is projecting to bleed：Avoiding leaving blood stasis inside tuna influences its mouthfeel；Treated product is upside down in dry and cold room fresh-keeping
Lash ship is sent in 3 hours, lash ship deck is provided with loop wheel machine at bow, and the lash ship lifts what dredger was pre-processed by loop wheel machine
Product, by carrying out crop, solution slicing pieces, divided rank, refrigeration, vacuum packaging successively to product, vacuum packaging is effectively dropped
Low product reduces the air pollution that product enters the quick-frozen process of strong convection, product is reached the hygienic examination criteria of relevant food；
By the product after vacuum packaging, quick freezing temperature, to -60 DEG C, takes out, is packed, be transferred to cold in refrigerated fish hold in 3-6 hours
Hide, its refrigerated storage temperature is 0-2 DEG C；Sent with charge free after reaching port city using low temperature logisticses market, it is ensured that product quality.
