Description
Technical field
The present invention relates to aquatile open-mouthed bait processing technique field, be specifically related to the survey of artemia cysts Raw material processing ratio
Determine method.
Background technology
Artemia is also referred to as saline fairy shrimp.Folks of china is also referred to as salt insect or shrimps.Arthropoda, first is belonged in classification
Shell subphylum, branchiopod guiding principle, Anostraca, saline fairy shrimp section, genus artemia.Artemia is as a kind of important food organisms and good reality
Test animal material, be constantly subjected to the extensive attention of people.
But in the artemia cysts course of processing, in artemia cysts raw material in various degree mix the impurity such as silt, empty chorion, existing
Industry standard SC/T 2001-2006 defines the method measuring artemia cysts impurity, but expends the time in actual application
Long, it is not easy to operation, is not suitable for artemia cysts processing enterprise and quickly measures impurity content and be processed into during purchase raw material
The requirement of product rate.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned defect of the prior art, quickly measures for convenience of artemia cysts processing enterprise
Impurity content in artemia cysts raw material, and quickly calculate purchased raw material artemia cysts and can produce the ratio of fine work artemia cysts,
Provide a set of assay method being applicable to measure different regions artemia cysts Raw material processing ratio.
To achieve these goals, the technical scheme that the present invention provides is: the assay method of artemia cysts Raw material processing ratio,
Comprise the following steps:
1) accurately weigh artemia cysts raw material 100g, obtain material sample weight amount；
2) take the separatory funnel of a 1L, add the saline of 25 ° of B é of 1L, the artemia cysts raw material weighed is added separatory funnel, fills
Divide stirring, then soak 20 minutes；
3) by funnel, the impurity being deposited to bottom is released, and, is allowed to dry by water only meanwhile, only retains artemia cysts in funnel；
4) by the artemia cysts in funnel from the funnel beaker pouring a 250mL into suitable for reading, with appropriate fresh water by residual halogen worm's ovum
It is flushed into beaker, separately takes the separatory funnel of a 1L, the artemia cysts in beaker is poured into wherein, then add water to 1L, fully stir
Soak 1 hour after mixing；
5) after 1 hour, artemia cysts is deposited to funnel bottom, and empty chorion climbs up on top of the water, with the screen cloth sewing that mesh size is 150 μm
One specification is the mesh bag of 20cm × 20cm, is put in mesh bag with current by the artemia cysts being deposited to bottom；
6) being drained by the moisture in mesh bag, then blow 10 minutes with the hot blast distance mesh bag 10cm of hair-dryer, Blower power is
1500w～2000w, the artemia cysts scales/electronic balance weighing after drying up, it is precipitated the example weight numerical value of separation；
7) from the artemia cysts dried up, weigh 2.0g sample, put into mensuration moisture in moisture test apparatus；
8) the example weight numerical value of the precipitate and separate that the material sample weight amount that obtains with step 1), step 6) obtain and step
7) moisture obtained calculates the processing ratio of artemia cysts raw material.
Further, the assay method of above-mentioned artemia cysts Raw material processing ratio, in described step 8), the meter of processing ratio
Calculation formula is:。
Principle: artemia cysts raw material fully soaks in saturated brine and fresh water, wash after, remove the impurity such as silt, ghost,
Remove moisture the most again, obtain the weight of pure artemia cysts；With raw material weight divided by pure artemia cysts weight, it is multiplied by 0.9(and removes
The water content of 10%), finally give the coefficient being processed into 1 part of fine work artemia cysts needed raw material artemia cysts.
The invention have the benefit that the assay method of the artemia cysts Raw material processing ratio that the present invention provides, its emphasis exists
In by going the removal of impurity, moisture, calculating the raw material artemia cysts required for 1 part of fine work artemia cysts of processing, compare SC/T
2001-2006, operability strengthens, time-consumingly shortens, and more directly perceived, during pension parachute, processing artemia cysts more
Easily operation.
1., with separatory funnel separation impurity, empty chorion and artemia cysts, efficiency is high, easily operates, and speed is fast.
In removing silt and hole chorion the two step, the way that this method is used is directly from separatory funnel
Portion directly releases.The first step is to be released by the silt precipitated in saturated brine, and second by fresh water after removal silt
Artemia cysts is released.Operating than in SC/T 2001-2006, method is easy, speed is fast.
The method of SC/T 2001 regulation, the most time-consuming, it is slower that thin latex tubing absorbs silt；Next is not easy to blot only, no
As separatory funnel put thorough；3rd, bad control, inhale with thin latex tubing and easily the thing that need not siphon away also is siphoned away, no
As controlled freely with separatory funnel.
2. ghost is removed more thorough.This method stands after being sufficiently stirred for by the artemia cysts removing the impurity such as silt hour, than
In standard SC/T 2001, the stipulated time (20 minutes) is long, and artemia cysts separates more abundant with ghost.
3. to be dried link easy and simple to handle for this method, and precision is high, saves more than 23 hours.
The method of the present invention is the mesh bag with screen cloth one 20cm × 20cm of sewing that mesh size is 150 μm, will precipitation
Artemia cysts to bottom is put in mesh bag with current, is then directly dried in mesh bag, and this process does not results in the damage of artemia cysts
Losing, precision is higher.In standard SC/T 2001, using method can cause artemia cysts to stick on screen cloth, in being transferred to weighing botle
The loss of artemia cysts can be caused due to misoperation, thus affect result.
Because employing moisture test apparatus, the dry of this method is that artemia cysts is blown 10 points by direct hair-dryer in mesh bag
Clock, dries up artemia cysts surface moisture, then measures water content with moisture test apparatus, saves more than 23 hours；Standard SC/T
Specify in 2001, " being dried through 24 hours ", could survey after constant weight.
4. the present invention is finally directly to measure process required for 1 part of fine work artemia cysts former with the formula summed up voluntarily
Material artemia cysts.Raw material artemia cysts impurity and the content of moisture can be reflected more intuitively, at pension parachute, processing artemia cysts
During be easier to operate to.
In sum, this method is designed by the characteristic for raw material artemia cysts, and required facilities and equipment is simple, operation letter
Just, detection speed is fast, it is adaptable to the impurity determination of raw material artemia cysts.
