Abstract
The present invention discloses a method for storing mulberry cocoons, wherein the method comprises the following steps: (1) collecting the mulberry cocoons, and eliminating the inferior mulberry cocoons; (2) tiling the fine cocoon on a cold preservation box with ventilating openings, transferring into an ice house for cold preservation and executing shading protection; and (3) timely changing the air of ice house, wherein the temperature of ice house is 4-8 DEG C, and the relative moisture is 60-70%. The method of the invention can store the mulberry cocoon with a long time and avoids the negative effect of high-temperature baking method. Furthermore the reelability percentage of cocoon can be increased for more than 10%. The production volume and quality of raw silk are increased. The cleanliness of raw silk can be increased for 1-2 scores.
Description
Technical field
The present invention relates to a kind of storage practice, be specifically related to a kind of method of preserving bombyx mori cocoon.
Background technology
Silkworm (Bombyx mori L.) by artificial domestication more than 5700 year, belongs to Lepidoptera Bombycidae complete metamorphosis in China, comprises four worm attitudes of ovum, larva, pupa and adult (moth) from generation to generation.Larva weaves silk to the later stage and cocoons, and pupates in cocoon, about 15 days pupa time.In order to obtain complete cocoon, traditional handicraft is that the method that adopts high temperature to smoke is killed the pupa of living in the cocoon after will the good cocoon of knot gathering, and reaching the purpose of long preservation bombyx mori cocoon, is the filature industry cocoon of supplying raw materials.
Yet, because the seasonality that silkworm produces is very strong, silkworm time of cocooing of being placed on small straw bundles to spin cocoons is all very concentrated, therefore require bombyx mori cocoon purchasing station (cocoon station) to finish with interior all silk cocoon high temperature are smoked in 1 week, otherwise will appearance moth phenomenon, form " moth mouth cocoon ", because " moth mouth cocoon " normal filature has lost due value.This shows that the used automatic cocoon-baker in cocoon station generally only utilizes (spring and autumn) twice the whole year, 1 year accumulative total is used and is no more than 15 days, thereby availability is very low; Simultaneously, this automatic cocoon-baker price higher (at present automatically cocoon-baker every about 90,000 yuans) has caused the waste of the idle and fund of equipment.
On the other hand, because what adopt is that the method that high temperature is smoked is killed the pupa of living in the cocoon, the outer sericin of silk can Yin Gaowen and produce sex change, causes that reelability percentage descends in the silk reeling process, directly influences the output of raw silk.In addition, this high temperature is smoked specification requirement height, the trivial operations of method, and misoperation will cause pupal cell to break, and cocoon layer is polluted in pupal fat and content outflow thereof, forms bad cocoons such as mimeograph cocoon and yellow spotted cocoon, influences the grade of raw silk.
Therefore, develop a kind of method that can preserve bombyx mori cocoon for a long time, can continue for the filature industry cocoon of supplying raw materials, avoid high temperature to smoke the negative effect of method, have the positive effect of reality.
Summary of the invention
The purpose of this invention is to provide a kind of method of preserving bombyx mori cocoon, is the filature industry cocoon of supplying raw materials with what continue.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of method of preserving bombyx mori cocoon comprises the steps:
(1) gather bombyx mori cocoon, bad cocoon is removed in choosing;
(2) good cocoon is tiled in the refrigerating box that has air vent, and sends in the freezer and refrigerate, the shading protection; The temperature of described freezer is 4～8 ℃, and relative moisture is 60～70%;
(3) described freezer is carried out the timing ventilation.
Above, the bombyx mori cocoon in the described step (1) is gathered the silk cocoon of preferably being placed on small straw bundles to spin cocoons 5～7 days; Cold storage capacity in the described step (2) is selected by actual conditions, such as, when a small amount of silk cocoon (≤100kg) can select the temp. and humidity incubator for use, a large amount of bombyx mori cocoons (＞100kg) optionally use underground freezer; Good cocoon in the described step (2) is tiled in the refrigerating box, is advisable vertically to be no more than 5 cocoons.Ventilation operation in the described step (3) is wanted timely ventilation during for employing temp. and humidity incubator, and is dead to prevent the pupal cell anoxia asphyxia; And when adopting the freezer storage, should build between the ventilation buffering on the freezer doorway, do not influence the purpose of indoor temperature to reach ventilation.
In order to guarantee the feasibility of said method, should be behind the bombyx mori cocoon warehouse-in, sampling in two days is 1 time in preceding 10 days, sampling in per 5 days once after 10 days, write down temperature and humidity in the freezer, and suitably adjust, observe the developmental state of mulberry silkworm chrysalis in conjunction with the developmental state of pupal cell.Refrigerate after 10 days, it is slightly shrivelled pupal cell to occur, belongs to normal phenomenon.If dead pupa phenomenon occurs, major consideration is that humidity is excessive, and the cocoon layer air capacity of soils is low, causes and is choked to death, and less important Consideration is indoor anoxic and suffocating of causing.
In the technique scheme, in described step (2), earlier the temperature of freezer is transferred to 10～12 ℃, humidity and is transferred to 60～65% and puts into refrigerating box, cushion after 24 hours, again the temperature of freezer is transferred to 4～8 ℃, relative moisture and is transferred to 60～70%.
In the technique scheme, the deposit position of described refrigerating box is changed every other day.This is in order to control the even temperature-sensitive of silk cocoon.
Operation principle of the present invention is: utilize low temperature to suppress the growth of mulberry silkworm chrysalis, under the environmental condition that this programme is selected for use, the developmental process of pupal cell can be suppressed, and makes the long-term maintenance of the interior pupal cell of cocoon fresh and alive, the similar hibernation-like state that is in, thus realized the purpose of long-term living pupa and cocoon-reeling.
Because the employing of technique scheme, compared with prior art, the present invention has following advantage:
1. the present invention utilizes the mode of refrigeration to store bombyx mori cocoon, and selects suitable temp. and humidity, thereby can preserve bombyx mori cocoon for a long time, has avoided high temperature to smoke the negative effect of method; Practical application proves, adopts reelability percentage that method of the present invention can improve silk cocoon more than 10%, improved the grade of raw silk, and the raw silk cleanliness can be high 1～2 minute.
2. the present invention can preserve bombyx mori cocoon for a long time, and therefore follow-up filature can directly utilize pupa alive to carry out, and the pupal cell behind the living pupa and cocoon-reeling can be used as the raw material of developing food products, improves comprehensive benefit.
3. the present invention is easy to operate and cost is lower, has a good application prospect.
