Abstract
The invention discloses a storage and preservation method for fresh cocoons before reeling. The storage and preservation method comprises the following steps: pupated fresh cocoons purchased by farmers are put into cocoon cases with six ventilated surfaces and the amount of the fresh cocoons contained in each cocoon case is not more than four fifths; finally, the cocoon cases filled with the fresh cocoons are stacked in a refrigeration house and are coldly stored after being rapidly frozen and the temperature in the refrigeration house ranges from minus6 DEG C to 0 DEG C. The storage and preservation method for the fresh cocoons before reeling disclosed by the invention can keep a natural state of the cocoons very well and the influence on silk quality is small; the problems that a lot of energy needs to be consumed and atmospheric pollution is caused in a traditional cocoon drying process are solved; a preservative is not added in the whole process so that the processing reutilization of silkworm pupa is guaranteed; the storage and preservation method is simple and convenient to operate and low in cost, and brings greater economic benefits to reeling mills.
Description
Technical field
The present invention relates to the processing treatment technology of fresh silk cocoon, specifically the storage preservation method before a kind of fresh cocoon reeling.
Background technology
After fresh cocoon purchase, generally adopt function drying stove for silkworm cocoon to bake dried cocoon, enter storage at normal temperature in cocoon storehouse, for cocoon cooking, filature and silkworm chrysalis processing, this is traditional processing technology routine.The aliphatic acid such as silk cocoon, in the 105～l10 DEG C of baking process of 6～8 hours, causes cocoon sericin albuminous degeneration, and pupa albumen is apt to deteriorate, pupal fat become sour because of oxidation, produce different hiding, and affect further deep processing.Fresh cocoon high-temperature baking and the traditional handicraft that forms a set of dried cocoon cocoon cooking and filature exists following harmful effect: (1) cocoon cooking, wrapping wire process sericin degumming loss percentage are larger, cause reel silk from cocoons folding to increase; (2) reelability percentage reduces, and causes output to reduce; (3) class joint increases, and affects the quality of raw silk; (4) silk cocoon dries rear protein denaturation, and pupal fat becomes sour, and produces peculiar smell, and deep processing is caused to certain influence.
The direct silk reeling technology of fresh cocoon not only can solve the defect existing in cocoon drying, and omits roasting procedure, and energy-saving and emission-reduction, improve the performance of enterprises; In addition, under the promotion of fresh cocoon Techniques of preserving development, the perfect great technological change that must realize filature industry of the direct silk reeling technology of fresh cocoon.If but fresh cocoon storage technology is improper, easily causes silkworm chrysalis deactivation.The pupal cell of deactivation contains a large amount of protein and moisture, easily rots, and the quality of impact silk and the utilization of pupa must be carried out Preservation Treatment to silkworm chrysalis for this reason, extend the fresh and alive time of silkworm chrysalis, ensure effective comprehensive utilization of silk quality and silkworm chrysalis.
Open source literature has also been reported the preservation method of fresh cocoon, as:

Detailed description of the invention
A storage preservation method before fresh cocoon reeling, comprises the following steps:
(1) the fresh cocoon after pupating is placed in six ventilative cocoon frames, every cocoon frame fills fresh cocoon amount and is no more than 4/5ths of its capacity;
(2) again cocoon basket isosceles triangle is stacked in to cold storing and fresh-keeping in freezer, while just entering freezer, will be cocoon precooling, make cocoon fully cooling, then cocoon basket is stacked up, the high generally unsuitable more than ten cocoon basket of heap, and keep 20cm space with freezer surrounding body of wall, so that air circulation circulation is conducive to silkworm chrysalis in fresh cocoon and breathes; Keep the temperature in freezer to be controlled at-6～0 DEG C, suppress the vital movement of pupal cell, keep silkworm chrysalis fresh and alive and do not change moth.
Described cocoon frame is plastics cocoon frame or bamboo cocoon frame.
In the time that production and processing needs, the fresh cocoon in freezer is taken out, select to fall after dupion, light defective cocoon, lower rotten cocoon and can be directly used in fresh cocoon processing.
Effect compared with existing fast cooling method, at present some bibliographical informations are to be placed in-18～-20 DEG C of Cold storage in the refrigerators by disposable fresh cocoon, can cause like this silkworm chrysalis death, can not get fresh pupa, lose a lot of nutritive values, and speed is as cold as after-18～-20 DEG C, after filature, the quality of silk declines to some extent, easily fracture of wire, and affected the quality of fresh silkworm chrysalis, having reduced silk cocoon filature byproduct is the value that enterprise creates.
application Example
Embodiment 1
Guangxi silk cocoon source mill, before 2012, do not grasp storage preservation method of the present invention, can only adopt traditional dried cocoon filature, filature again after drying by silk cocoon, need a large amount of energy and dry silk cocoon, and the silkworm chrysalis when silk cocoon is dried in also by it is dried, the added value of silkworm chrysalis is reduced; After 2012, this source mill has grasped the storage preservation method before a kind of fresh cocoon reeling of the present invention, silk cocoon after pupating is placed in to freezer fresh-keeping, thereby can carry out fresh cocoon reeling, save the link that silk cocoon is dried, reduce the use of the energy, meet the industrial policy of country's " energy-saving and emission-reduction ", the recycling of silkworm chrysalis is simultaneously worth significantly and improves.2013, this source mill grasped and has adopted fresh cocoon to carry out filature Billy after storage preservation method of the present invention to increase approximately 20000 yuan by dried cocoon filature silk per ton profit.
