Abstract
A processing technology for refining the dried artemia cysts comprises the step of separating and removing impurities twice by using 180-200% sodium chloride aqueous solution and fresh water. 8 per mill of calcium hypochlorite solution is used as flushing fluid, and the flushing fluid has a sterilization effect at the same time. And drying the artemia cysts until the water content is 5-15%. The method has an active separation process, dead eggs are separated and discarded by an air separation method, and the dead eggs are sterilized and disinfected by 5800-6200 LUX ultraviolet lamps. The sterilization is complete and no residue exists. The method has the advantages of advanced process, stable technology, 92-94% of artemia egg hatchability, 1: 3.1-3.2 of worm emergence rate and 52-54% of egg worm protein.
Description
Technical field
The present invention relates to aquaculture industry open-mouthed bait dried artemia cysts, the particularly processing technique field of refined dry artemia cysts.
Background technology
The halogen worm is the open-mouthed bait of fish in the culture fishery, shrimp, crab seedling.The halogen worm is to be come out by artemia ovum hatching.Artemia cysts has dried, wet branch; Dried artemia cysts has the branch of woollen and refining material again.The refined dry artemia cysts of processing in the problem aspect the processing technology is both at home and abroad at present: in process, artemia cysts is regardless of anyway, and there are defective in removal of impurities, flushing and sterilization method.The saline solution sodium chloride-containing of using during relevant unit's removal of impurities both at home and abroad about 300 ‰, artemia cysts water content height after the layering.Relatively poor during flushing with the flushing with clean water effect.With potassium permanganate, formalin sterilizing, raffinate remains in the product easily, and this is harmful to product, and disinfection effect is also relatively poor.Therefore, the artemia ovum hatching rate is low, and the artemia cysts insect pests rate is low, and protein content is also low.Domestic artemia ovum hatching rate is 75%, and dried artemia cysts insect pests rate is 1: 1.8, and protein content is 17%; U.S.'s technology in this respect is more advanced, and its artemia ovum hatching rate is 86%, and dried artemia cysts insect pests rate is 1: 2.8, protein content 42%, but this technical indicator is also not very desirable,
Summary of the invention
Existing refined dry artemia cysts processing technology is made up of the removal of impurity, flushing with clean water, dehydration, chemical disinfection, drying, packing, deepfreeze operation.
Key improvement of the present invention is:
One, the active separation, artemia cysts drying, the active seperator in sterilization back, artemia cysts is separately anyway.Dead ovum discards, and the ovum of living remaines in the 125 order silk screens.
Two, calcium hypochlorite solution flushing, artemia cysts after removal of impurities with the flushing of the 8 ‰ calcium hypochlorite aqueous solution, dash extremely flushing liquor off the net Clear ﹠ Transparent till, the calcium hypochlorite solution of washing out in the artemia cysts with fresh water is residual then, this process also plays the sterilizing effect.
Three, ultraviolet radiation for sterilizing and disinfecting, isolated ovum alive uses ultraviolet lamp at 5800-6200LUX illumination sterilizing.Qualified the aseptic worm of microscopically for sterilization, live ovum noresidue and sterilization behind the sterilizing thoroughly.
Four, 180-200 ‰ sodium-chloride water solution and twice removal of impurity of fresh water are used in the removal of impurity.Moisture lower in the artemia cysts after the removal of impurity, be an advantage.
The hatching m of refined dry artemia cysts, basic similar to existing hatching m.The present invention has one section distinguished preparation before hatching.That is: the refined dry artemia cysts that takes out from refrigerated room places the space 48 hours of normal temperature, uses the sea water immersion 3 hours of sodium chloride-containing 20～35 ‰ again, oxygenation simultaneously 3 hours.Consistent with prior art in addition.
The present invention is stored 8 procedures and is formed by the removal of impurity, calcium hypochlorite solution flushing, dehydration, drying, active separation, ultraviolet radiation for sterilizing and disinfecting, packing, refrigeration.Existing division is as follows:
The removal of impurity, the woollen input of the artemia cysts that will wet stirred in the trash separator, and the sodium chloride-containing 180 of reinjecting～200 ‰ aqueous solution is started agitator, makes its natural subsidence layering after stirring, and impurity is sunken to lower floor, and its separation is discarded.Artemia cysts filters in the income 125 order silk screens in the upper solution.Artemia cysts places fresh water fully to stir back natural subsidence layering in will netting again, pulls out above empty chorion floats on to discard, and artemia cysts filters and closes in the silk screen.
Calcium hypochlorite solution flushing is washed artemia cysts in the 125 order silk screens with 8 ‰ calcium hypochlorite solution, and flushing liquor off the net is clear to be qualified, washes out calcium hypochlorite raffinate in the artemia cysts with fresh water again.
Dehydration is packed artemia cysts into and is dewatered in the dewater unit, sloughs attached water in the artemia cysts.
Drying is delivered to the artemia cysts after the dehydration in the drier, the drum hot blast, and under 36～39 ℃ of temperature, it be qualified doing to the artemia cysts moisture 5～15%, best water content is 10～12%.
The active separation, dry back artemia cysts mixes anyway, with pneumatic concentration the life or death ovum is separated, and the ovum collecting of living gets up, and dead ovum discards.
Ultraviolet radiation for sterilizing and disinfecting places the drying artemia cysts of living under the ultraviolet lamp and carries out disinfection, and illumination will reach 5800-6200LUX, till aseptic in the ovum (coccus, bacillus, vibrios, mould) worm.
Packing, the viable bacteria worm's ovum that sterilizing is qualified is loaded in plastic sack or the box, reinstalls in the packing case.
Refrigeration is stored, and the work artemia cysts of will case places-19～-24 ℃ of freezers to store, and the shelf life is 24 months, but in the shelf life incubation time.
Advantage of the present invention is, technology advanced person, and technology is reliable, compares incubation rate height, insect pests rate height with existing technology, artemia cysts proteolipin content height, and aseptic, nontoxic, harmless.
The present invention does not have figure
Embodiment
Embodiment 1:
It is a collection of to get the artemia cysts woolen cloth, throws to the removal of impurities agitator that is full of sodium chloride-containing 190 ‰ aqueous solution, discards two-layer impurity up and down after stirring, twice sedimentation layering.Artemia cysts is taken in the 125 order silk screens, with the artemia cysts in the 8 ‰ calcium hypochlorites flushing silk screen, rinse well with fresh water the clear back of flushing liquor off the net, slough attached water in the artemia cysts with Φ 800mm stainless steel centrifuge, again artemia cysts is sent in the drier 38 ℃ of heated-air dryings to the ovum moisture 10%, carry out activity with farmers''s windmill again and separate, discard dead ovum.Under the 5800LUX ultraviolet lamp, sterilizing is the refined dry artemia cysts to aseptic worm.Get wherein 1 kilogram of refined dry artemia cysts, do hatching preparation earlier, hatch by current techique then, the technical data that obtains is as follows:
Incubation rate 92% goes out 3.1 kilograms of halogen worms;
Contain protein 53% in the ovum.
Embodiment 2:
It is a collection of to get wet artemia cysts, throws removal of impurities processing and the calcium hypochlorite solution flushing carried out in 200 ‰ sodium-chloride water solutions as embodiment 1 to filling.Naturally after sloughing the attached water of artemia cysts with bamboo sieve and silk screen bag then, send to again and under 39 ℃ of temperature, be dried in the ovum moisture 6% in the drier.Be that 6000LUX ultraviolet lamp sterilizing is to aseptic worm with illumination then.Be the refined dry artemia cysts, get 1 kilogram of refined dry artemia cysts and hatch, the result is as follows:
