Description
Technical field
It is particularly a set of to be applied to clam class, blood clam class, mussel the invention belongs to shellfish coarse working techniques field in Marine agriculture
The specification sorting of the closed shell type shellfish such as class, oyster class and surface decontamination techniques, specifically a kind of closed shell shellfish catch rear roughing
Processing method.
Background technology
Closed shell type shellfish is that a variety of shellfishes of Mollusca are referred to as, its hull shape rule, closes tight after water outlet, and silt is difficult to
Into.Main economic species includes：Clam class mainly includes Ruditapes philippinarum, clam, Clam Mactra chinensis, Ba Fei clams, clam, Xisi, famous beauty in the late Spring and Autumn Period
Tongue, mirror clam etc.；Blood clam class mainly has blood clam, stalwart blood clam, mud blood clam etc.；Mussels mainly have Mytilus galloprovincialis, Perna viridis, Trachyostracous mussel etc.；
Oyster class mainly has Portuguese oyster, long oyster, Crassostrea rivularis, the huge oyster in Hong Kong etc..Closed shell shellfish is a kind of important economy
Shellfish, the South and the North have large-scale farming, and yield accounts for more than the 2/3 of China's shellfish total output, comparatively, cultivation risk is small,
Small investment, relative cost are low, yield is high, and industrial status is particularly significant.
Clam class, blood clam class are moved in beach or the substrate in shallow sea, the clam class and blood clam class caught on a large scale using ship drag harrow
With impurity such as a large amount of gravels, shells, it is difficult to remove by flushing merely；Oyster, mussel are moved in seawater, it is substantially static not
It is dynamic, the parasite of shell table attachment silt and stubbornness.The method bag typically taken the purified treatment of closed shell type shellfish in the past
Include：Clear shellfish machine screen cloth rolls filtering, removes excessive or too small block；Flowing water rinses, and removes silt, part broken shell and close
Spend less block；It is artificial to sort out sandstone, damaged individual, shell and other impurities.3 steps more than, mixing
Impurity can be removed totally substantially, but shortcoming is obvious：Screen filtration step improves the breakage rate of shellfish；Labor intensive is more, increases
Add cost of labor；Processing speed is slower, especially in stage for fishing of concentration, often due to processing does not catch up with, limit the amount of fishing,
Reduce product quality.
The content of the invention
The purpose of the present invention is that in view of the shortcomings of the prior art, and propose a kind of closed shell shellfish catches rear roughing processing side
Method.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of closed shell shellfish catches rear roughing processing method, including step is as follows：
(1) iron screening and choosing：The iron sieve apparatus used includes both parallel and the upper strata scalping put and lower floor's dusting covers, on, under
Layer compass screen surface spends angle with horizontal into 15 degree -20, and the top of upper strata scalping and lower floor's dusting cover is affixed by entablature, vibration motor
Output end is affixed with entablature, drives entablature to do front and rear vibrations, and on upper strata, the top placement lower feed box of scalping, will be sorted shellfish
Class by lower feed box outlet slide to upper strata scalping top, the shellfish being sorted by upper strata scalping and lower floor's dusting cover surface slide to
Bottom；
(2) the above-mentioned shellfish sorted out is subjected to mud buoyancy sorting respectively：Mud buoyancy sorting unit includes top
The fiberglass cell body of opening, apopore is set in the middle part of a side wall of fiberglass cell body, set in the bottom of apopore opposing sidewalls
Water hole is inserted, water circulating pump is set on the circulating water pipeline between apopore and blasthole, adds seawater extremely in fiberglass cell body
More than apopore, shellfish is added into water, then add sandy loam, started water circulating pump stirring 2.0-3.0min to mixing, make
Untill shellfish is suspended in mud surface, it is then shut off water circulating pump and stands 0.5-1.0min, now, shell, impurity, damaged shellfish
Individual sinks to bottom, and complete individuals are suspended in top layer, pulls suspension shellfish out, is placed in plastic crate；
(3) flowing water rinses：The shellfish that above-mentioned mud buoyancy sub-elects is divided into the progress flowing water flushing on close screen cloth processed
0.5-1.0min is bright-coloured to shellfish shell table decorative pattern；
(4) artificial separation is carried out on above-mentioned close screen cloth processed, picks out and still remain in impurity therein and damaged individual；
(5) shellfish hypnosis：Glass fibre reinforced plastic groove is set, adds seawater, then adds sea ice, keeps frozen water to mix after melting a part
Compound state, by the shellfish income net basket after above-mentioned hand picking, to be pulled out after immersing the frozen water 8-20 seconds, clam son's shell closes,
In semidormancy state；
(6) nylon net bag is packed, and temporary transient storage temperature is between 5-10 DEG C.
Moreover, the amplitude of the front and rear vibrations of iron sieve be 8cm-10cm in the step (1), vibration frequency for 80 times -120 times/
min。
Moreover, scalping and lower floor's dusting cover are that the grid of iron wire establishment sieves to the step (1) at the middle and upper levels, the length of side of grid sieve
Maximum outside diameter big 5% than shellfish will be sorted.
Moreover, the sea water specific gravity of sandy loam is added in the step (2) between 1.18g/mL-1.22g/mL.
Moreover, the control time that frozen water is immersed in the step (5) is specially：On the basis of the long 2.5cm shellfishes of shell, immerse
Frozen water is 8 seconds, and shell length often increases by 10%, immerses frozen water time increase by 1 second.
The advantages and positive effects of the present invention are：
Present invention firstly discloses a set of techniqueflow suitable for the purification of closed shell shellfish sorting, has inexpensive, efficient
Rate, simple operation and other advantages.To having following features than conventional closed shell shellfish sorting purification method, the present invention：
1st, clean-up effect is excellent：During conventional closed shell shellfish sorting purifies, sorting separates with purification, general first
Rinsed by simple, then carry out artificial separation, low production efficiency, handled of poor quality.The present invention uses pipelining mode, will
Sorting incorporates a set of flow with purification, and sorting step is placed in into the 1st step, can be effective during the 2nd step mud purification
Removal damaged individual caused by due to sorting, the shellfish of technology purification, shell color is attractive in appearance bright-coloured, no breakage.
2nd, equipment is simple, easy to operate：Equipment needed for the technology is simple, low cost, in addition to the separating sieve of the 1st step, other
Equipment can make temporarily.Therefore, the technology is suitable to vast common fisherman's use, and user can be according to the specification of target shellfish
The separating sieve of different pore size is set, the volume of the 2nd step mud sorting groove can be set according to the size for the treatment of capacity.
3rd, production cost is low：The technology introduces mechanical sorting and mud saves labour, reduces production cost, especially
It is the sorting of the 2nd step mud, quick separating, including shell, silt, sandstone, damaged individual etc. can be carried out to impurity in target shellfish,
A large amount of labours are saved.
4th, production efficiency is high, strong adaptability：According to the streamline of 1 10 people of the technical organization or so, shellfish can be handled daily
More than 50 tons of class；The technology can carry out purified treatment to the bivalve shellfish of all closed shells, low to site requirements, both can be in operation ship
It is only upper to operate, it can also be transported to plant operations.
5th, shellfish is injured small：In processing procedure, without larger environmental change, not using excitant medicament, shellfish is hindered
Evil is small, is advantageous to the holding of the survival rate in later stage storage and transport process.
