Description
Technical field
The present invention relates to the euphausia superba powder rapid drying device of aquatic products processing equipment, more particularly to a kind of boat-carrying.
Background technology
Krill (Euphausia superba Dana) is a kind of small-sized shellfish for living in South Pole marine site,
Marine stock biomass is about 1.25~7.5 hundred million tons, is not yet sufficiently developed at present.Krill is at present mainly by ship
On be directly processed into euphausia superba powder or freezing krill.
Euphausia superba powder has higher protein, fat content, and amino acid composition is rationally；Using euphausia superba powder as raw material
The product research of exploitation also achieves positive progress.But the quality of current euphausia superba powder is generally poor, and research is found, influences
The factor of euphausia superba powder nutrition and quality characteristic mainly includes：Time, place and the condition of capture, the quality of raw material and fresh
Degree, process technology and equipment, technology of storage and transport and condition etc..But at present on the processing of krill shrimp med and the report of storage technique
It is less.
Euphausia superba powder is using krill as raw material, and the one kind obtained through processes such as boiling, dehydration, drying, crushing is produced
Product, feed, krill oil extract etc. are mainly used at present；Due to containing a large amount of enzymes in krill body, South Pole phosphorus can be caused
Shrimp self-dissolving.Therefore, krill must be aboard ship processed as early as possible after capture.The euphausia superba powder of high-quality should adopt
Aboard ship processed with the complete krill in 1~2h after capture.
Existing krill process technology is mainly to have used for reference the Processing Technology Development of fish meal.But fish meal and shrimp
Powder is having larger difference in terms of property of raw material and product performance.As fish meal raw material fish protein composition with krill have compared with
Big difference；Fat is required as far as possible low in fish meal process, and the reservation fat for trying one's best more is required in shrimp med process；Fish meal
Pigment problem is not present in process, the pigments such as degradable astaxanthin be present in shrimp med process.On the whole, shrimp med
The technical issues that need to address are far more than fish meal in process.
At present, the production majority of euphausia superba powder is completed on ship, the shrimp med production line master of existing euphausia superba
To be made up of digesting apparatus, dehydration equipment and drying equipment, krill is laggard by boiling, centrifugation or press dewatering process
Enter to drying machine, it is different according to dehydration equipment, into drying equipment krill moisture content of material between 55~65%, spiral
The moisture of material can be reduced to 55% or so by press apparatus, and horizontal spiral centrifuge can contain material dewatering to moisture
Amount 65%.Shrimp med moisture typically is more beneficial for storing and transported below 12%；Therefore, the major function of drying equipment is just
It is that moisture is reduced to less than 12% from 65% or 55% on the premise of shrimp med quality is ensured.It is presently used for shrimp med production
Ship-borne equipment is mainly disk drying machine, and disk drying machine is a kind of drying device of indirectly heat, and steam passes through a large amount of
Disk and equipment cavity interlayer exchanged heat, so as to heat shrimp med, evaporate moisture.The drying equipment is widely used in fish
Powder machining production line.Due to fish meal in process, its fat is removed in expressing process, the fat of final products
Content is lower, and the protein content of product is higher, and the higher grade of fish meal, and protein ingredient is during long-time at elevated temperature
Quality decline will not occur；And shrimp med, in particular for the shrimp med of food processing, it is mainly used in the extraction of antarctic krill oil, its
Fat content is higher, is typically fluctuated in the range of 12~22%, so high fat content, in the drying process, experienced height
The effect of warm high humidity, oxidation Decomposition easily occurs, while the astaxanthin in euphausia superba powder is even more the composition of oxidizable degraded.Mesh
Before, degraded for lipid oxidation, there is substantial amounts of research to show that high temperature, the long duration of action of high humidity can promote the oxygen of fat
Change and decompose；According to production line test data on the existing ship of certain company：Disc type drying equipment is during continuous service, krill
Material enters drying equipment from dehydration device, is finished to drying, and elapsed-time standards is up to 1.5~2 hours, the temperature of final material
For 95 DEG C, krill meal lipid oxidation is serious, causes free fatty acid content to raise, and astaxanthin degraded is serious, and shrimp med color is in dark
Brown.Foreign countries also have some krills fishing processing company to produce the higher euphausia superba powder of quality, but it is used more
Vacuum disk drying machine, by the way of low temperature drying, the shrimp med quality produced is preferable, but needed for being dried in vacuo
Energy consumption is higher, and arid cycle is grown, and not exclusively steam consumes energy, and the holding of high vacuum also results in the energy on ship and largely consumed,
Equipment is complex simultaneously, its less stable, and its economy is poor.
In addition, marine vessel has diesel engine, generator and a boiler, the said equipment can produce substantial amounts of waste gas and remaining
Heat, this part of waste heat are directly released into environment, certain negative impact can be not only brought to environment, while also create heat energy
Loss.
The content of the invention
Present invention solves the technical problem that it is that drying equipment has drying in current euphausia superba powder boat-carrying machining production line
Time is long, drying temperature is high, moisture absorption, temperature of charge make active component degrade to material as moisture reduces rise repeatedly
Oxidation etc.；Either drying equipment manufacturing cost and use cost is compared with the problem of high, energy consumption is big, drying time is long, stabilization of equipment performance is poor；
The various diesel engines on krill dredger, generator and boiler produce substantial amounts of waste gas and waste heat, this part of waste heat simultaneously
It is directly released into environment, certain negative impact can be not only brought to environment, while also create hot loss of energy.
To solve the above problems, we have proposed a kind of euphausia superba powder rapid drying device of boat-carrying, the drying device
The rapid draing of euphausia superba powder can be realized, makes that active component will not be destroyed in euphausia superba powder drying process too much, simultaneously
Material moisture absorption repeatedly is avoided, meanwhile, energy consumption in drying process is reduced, the waste gas on krill dredger and waste heat is fully sharp
Use, reduce its influence to environment.
