Abstract
The present invention is a kind of method for killing silkworm pupae, it is characterized in that silk cocoon is put into bag or the container that is difficult to see through gas, subsequently oxireme gas is charged into and remains on wherein.Be more preferably silk cocoon is put into the bag that sees through gas and water vapour easily, again this bag put into bag or the container that is difficult to see through gas, charge into oxireme gas again.
Description
The present invention relates to method for killing silkworm pupae and the method that obtains the high-quality raw silk in the raw silk production process.
When making raw silk by living cocoon, the cocoon that the collection silkworm chrysalis becomes before the moth is followed the dry processing of its execution, and kills silkworm chrysalis and mildew-resistant.This drying is for example keeping down after a few hours temperature being fallen lentamente at 110 ℃, and locates to keep this experienced timetable of certain hour to carry out at 60 ℃.And will carry out drying according to suitable heat treatment time table in general farmers' is inconvenient.Therefore, generally be after each farmers' silk cocoon is collected in specific mechanism (dried cocoon field) aggregation process,, the raw silk quality of acquisition is significantly descended often because unsuitable drying allows the reelability percentage variation.
The present invention In view of the foregoing provides to get rid of and compiles the work that collects cocoon, obtains the simple method for killing silkworm pupae of high-quality raw silk as problem in each farmers' with high finished product rate.
In order to solve above-mentioned problem, the invention provides following such method for killing silkworm pupae.
That is to say that this method for killing silkworm pupae of the present invention is characterized in that cocoon is put into bag or the container that is difficult to see through gas, subsequently oxireme gas is charged into and remains on wherein.Be more preferably cocoon is put into the bag that sees through gas and water vapour easily.Again this bag put into the bag or the container of the body that is difficult to ventilate, charged into oxireme gas again.
Below, give an actual example is described in detail at this point particularly:
In the present invention, use oxireme gas, it is to use with other gas dilutions that but this oxireme gas does not use separately, the best be make oxireme gas and carbonic acid gas mist (hereinafter referred to as binary mixture (ダ イ サ イ De ガ ス).As binary mixture oxireme gas 10% is arranged, the mixture of carbonic acid gas 90% (being called the H10 binary mixture); Oxireme gas 20%, the mist of carbonic acid gas 80% (being designated hereinafter simply as the H20 binary mixture), oxireme gas 30%, carbonic acid gas are that 70%(is called binary mixture H30) etc.Except that epoxy ethylene gas and carbonating gas, also can add oxireme gas and hept-2-ene"-4-ketone two (Off ロ Application) mist of gas or other gas.
In pupa killing method of the present invention, cocoon is put into the bag that is difficult to ventilate, further charge into binary mixture and remain on sealing state, yet at this moment had better not directly put into cocoon the bag of barrier layer for gases, but earlier cocoon is put in the inner bag that gas and water vapour pass through easily, again this inner bag is put in the outer bag that is difficult to by aforementioned gas.If cocoon directly put in the outer bag that is difficult to see through gas and water vapour encloses gas again, just can carry out pupa killing, but the body fluid of pupa will flow out and soiled cocoon, and the danger of the commodity value of making decline is arranged.Paper is arranged, paper+synthetic resin film, synthetic resin film etc. as the bag that sees through gas and water vapour easily.As synthetic resin film, polyethylene film is for example arranged.As the outer bag 3 that is difficult to by gas, for example can use on Polythene Bag surface aluminising.Also can use the outer bag 3 of replacements such as glass, metal as the container that sealing is arranged.The size of bag just can so long as facility is gone up in operation.
Fig. 1 is the state diagram of this binary mixture of expression when injecting, and the inner bag that air capacity of soils is arranged 2 of putting into cocoon 1, again this inner bag is put into the outer bag 3 that is difficult to ventilate, and passes through injection device 5 injection binary mixtures by gas pump 4 in the bag 3 at this outside.Outer bag behind the injecting gas seals peristome by not shown envelope rank device.
In bag, charge into the amount of charging into of binary mixture, for example under the situation of binary mixture H20, be preferably per 1 cocoon and need 10-20ml gas, and the kind of gas and amount are as long as adjust to optimal situation according to situation at that time.In addition, the amount of putting into cocoon in inner bag 2 generally is 10-15Kg, but is not limited to this.When each cocoon charged into binary mixture H2015ml, it was promptly dead to cross 1 hour pupa approximately, still, for mildew-resistant, preferably it is intactly kept 2-24 hour.Keep defined after the time charging under the gaseous state, if open the outer bag 3 that is difficult to by gas, then pupa is dried naturally, and it is stained can not produce the cocoon that body fluid causes.In addition, because the assorted bacterium of fungi etc. died, thus do not have pollution because of the mould cocoon that causes, can long preservation.According to this pupa killing method, so owing to be not subjected to heat reelability percentage height on the cocoon, the fullness of silk is good especially.Moreover compare with existing heating means, because the color of cocoon is white, so can obtain high-quality raw silk.Again owing to can carry out pupa killing and mildew-resistant easily in for example each farmers' of breeding silkworms etc. and handle, so following advantage does not need to collect together cocoon in official hour, meanwhile in conveying, do not go out the excellent worry of moth yet, sericulture at distant location has also become possibility, helps to a great extent to give birth to
Production system.
Embodiment 1
Article 20, the silkworm chrysalis of work is put into the bag that the appearance and size that does not see through gas is 165 * 230mm, after the sealing, charges into binary gas H20 300ml with syringe, remains in 37 ℃ in thermostat.Subsequently, take in the bag with syringe and the gas 1.0ml in the silk cocoon, adopt the gas chromatographic analysis method to check oxireme gas and carbonic acid gas (CO every the time of defined
2) concentration result, as shown in table 1.In addition, also confirmed to keep the silk cocoon silkworm chrysalis wherein more than 2 hours to die.

Embodiment 2
The polythene film bag of 700 silk cocoons being put into aluminising (is of a size of 600 * 500mm), charges into after binary mixture H20 10.5ml kept 14 hours with sealing state, open bag again, silk cocoon is changed put into mesh bag and taken care of.The dead bones of the body of silkworm chrysalis are clean, and silk cocoon is white, even through keeping for a long time, also do not find mouldy.In addition, after gas charges into, produce moth through 1 hour be equipped with at least.

By above explanation obviously as can be known, if according to method for killing silkworm pupae of the present invention, owing to the heat that does not add to as prior art, so the high fullness of the reelability percentage of silk cocoon is good, so and because colour purity can obtain high-quality life in vain
In addition, the advantage that this method for killing silkworm pupae had is to implement easily in farmers' separately.
