Description
Technical field
The present invention relates to silk cocoon Techniques of preserving field, more particularly to a kind of dry silk cocoon store method.
Background technology
Silkworm (Bombyx mori L.) has been become completely in China by artificial domestication more than 5700 years, category Lepidoptera Bombycidae
State insect, from generation to generation including four ovum, larva, pupa and adult (moth) worm states.Larva cocoons to later stage spinning, is pupated in cocoon, pupa
15 days or so phase.Mulberry cocoon can be used for reel silk from cocoons raw silk, and raw silk is important silk spinning raw material.Dry silk cocoon, which refers to fresh silk cocoon, to be passed through at dry
Reason, reach as defined in suitable dry degree, can fill and wrap into storehouse storage, the silk cocoon of supply Silk Mill filature successively.
Dry silk cocoon is highly prone to the big infringement of the moulds such as aspergillus, Penicillium and Mucor during preservation is stored, and more
It easily breeds sprawling to wet environment, causes silk cocoon mould bad；It is simultaneously easily red by grain peat, cotton for storing the cocoon storehouse of dry silk cocoon
The insect pests such as earworm.Dried cocoon is thus subjected to reasonable shelf preservation, prevents from making moist, mouldy, rotten and insect pest, to ensure cocoon quality, root
Needed according to production, the quality raw materials cocoon that offer in good time is most appropriate to needed for filature production becomes cocoon station and Silk Mill compels the solution that is essential
The problem of.
The content of the invention
It is an object of the invention to：For above-mentioned problem, there is provided it is a kind of easy to operate, can effectively prevent from making moist,
Mouldy, antibacterial, rotten and insect pest dry silk cocoon store method.
In order to realize foregoing invention purpose, the technical solution adopted by the present invention is as follows：
A kind of dry silk cocoon store method, is comprised the steps of：
(1) the dry silk cocoon Jing Guo drying process is loaded in packaging bag, and drier is put into packaging bag, then tightened
Packaging bag；
(2) after storage being carried out into deinsectization processing with insecticide, drying is aerated, the temperature for then controlling storage is
20-25 DEG C, relative humidity 55-60%；
(3) packaged dry silk cocoon is moved in the storage treated through step (2), entirely stored in storage life,
The temperature control of storage is 20-25 DEG C, relative humidity 55-60%, until storage terminates.
It is preferred that in step (1), the drying process is vacuum freeze drying processing, and it is concretely comprised the following steps：By silk cocoon
After freezing 3-4h under conditions of -26 DEG C~-18 DEG C, 10-15Pa is evacuated to, the dry moisture content to silk cocoon is 10-12%.
It is preferred that in step (1), the drying process is with micro-wave vacuum case drying process, and it is concretely comprised the following steps
After silk cocoon is freezed into 3-4h under conditions of -26 DEG C~-18 DEG C, the silk cocoon after precooling is put into micro-wave vacuum case, taken out
Vacuum to 5-8Pa, microwave frequency 100-500MHz, the dry moisture content to silk cocoon is 10-12%.
It is preferred that in step (1), the drier is mixed by the raw material of following parts by weight：Porous-starch 5-10 parts,
Activated carbon 1-5 parts, attapulgite 1-5 parts, Nano Silver 0.2-1 parts, nano zine oxide 0.1-0.5 parts and Ground Cloves 5-10 parts.
It is preferred that the drier is mixed by the raw material of following parts by weight：It is 8 parts of porous-starch, 3 parts of activated carbon, recessed
Convex 7 parts of 2 parts of rod soil, 0.6 part of Nano Silver, 0.3 part of nano zine oxide and Ground Cloves.
It is preferred that the particle diameter of the Nano Silver is 50-100nm, the particle diameter of the nano zine oxide is 80-120nm.
It is preferred that after cloves is to be shredded to the preparation method of the Ground Cloves, the second that volume fraction is 45~55% is added
Alcohol, with ultrasonic wave extraction and centrifuged at a temperature of 65~75 DEG C, reclaim extract solution, repeated 2~3 times, merge extract solution, then pass through
It is concentrated under reduced pressure, dries, produce the Ground Cloves.
It is preferred that in step (2), the insecticide is pyrethroid insecticides.
It is preferred that the packaging bag is the thick polythene film bags of 0.10-0.12mm.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
(1) dry silk cocoon store method of the invention has carried out deinsectization processing before preservation to storage, using dry during preservation
Drying prescription carry out moisture absorption, drying, bacteria mildew-proof, and strictly control storage temperature and humidity, effectively prevent dry silk cocoon by
Damp, mouldy, rotten and insect pest, and the best in quality of dry silk cocoon is maintained, provide high-quality raw material cocoon for filature production.
(2) cocoon drying processing procedure of the invention is handled using vacuum freeze drying or micro-wave vacuum case is dried
Processing, high temperature drying is avoided, the original shape of silk cocoon, color and luster and functional characteristic is maintained, avoids the outer layer silk gum of silk
Albumen produces denaturation because of high temperature, causes reelability percentage in silk reeling process to decline.
(3) the dry silk cocoon of the present invention uses during preserving drier porous-starch, activated carbon, attapulgite, Nano Silver, receive
Rice zinc oxide and Ground Cloves mix, wherein, porous-starch, activated carbon and attapulgite three synergy, have stronger
Hygroscopicity, adsorb air in steam, prevent dry silk cocoon from making moist, be mouldy；Nano Silver and nano zine oxide are nanoscale, surface
Strong adsorption force, it can effectively adsorb and kill bacterium colony group in environment；Cloves also name clove tree, chicken tongue, are Oleaceae, and Genus Syringa is planted
Thing, enriched in china natural resources, it is distributed more widely, there are an antibacterial, anti-inflammatory, antiviral and other effects, the flavones in the ethanol extract of cloves
Class compound is both natural antioxidant, it may have significant fungistatic effect, has broad-spectrum antiseptic to many pathogenic microorganisms
Characteristic.Above composition is mutually coordinated, can effectively prevent dry silk cocoon from making moist, be mouldy and rotten, and then effectively extending the guarantor of dry silk cocoon
The matter phase.
(4) insecticide of the invention is pyrethroid insecticides, and it is to worms such as grain peat, double skin calabash shell serving as a dippers, pink bollworms
Evil has stronger lethality, can effectively prevent from being influenceed by insect pest during dry silk cocoon preservation.
