Problems solved by technology

[0004] In addition, because high temperature is used to kill live pupae, the sericin protein in the outer layer of cocoon silk will be denatured in response to high temperature, resulting in a decrease in the unwinding rate during the silk reeling process, which directly affects the production of raw silk; due to high temperature baking, technical requirements High, complicated operation, improper operation will cause the pupal body to rupture, the pupa oil and its contents will flow out, pollute the cocoon layer, and will form bad cocoons such as mimeograph cocoons and macular cocoons, which will affect the quality of raw silk

Embodiment 1

[0029] Example 1: A method for preserving silkworm cocoons

[0030] ⑴ Solution preparation, including,

[0031] Choose one or several combinations of CaCL2, MgCL2, NaCL, KCL, CaSO4, Mg SO4, Na2SO4, K2SO4, CaSO4, weigh a certain weight and dissolve in water, the final concentration is 15%, 20% and 25%, salt The weight of the solution is 3-6 times the weight of silkworm cocoons, and 3 times is better.

[0032] ⑵ Preparation of soaking container, including,

[0033] The size of the container is selected according to the weight of the silkworm cocoons, and the volume is 1.5 times the volume of the silkworm cocoons per soaking.

[0034] ⑶ Cocoon collection:

[0035] Collect 7-day-old cocoons of silkworms, remove bad cocoons, and weigh a certain amount into a net bag.

Abstract

The invention discloses a mulberry cocoon preservation method which is characterized by including the steps: collecting mulberry cocoons mounting for 5-7 days, soaking the mulberry cocoons in salt solution with the concentration of 15-25% for 24-72 hours, taking out mulberry cocoons and then naturally dewatering the mulberry cocoons until airing; lifting the mulberry cocoons every 12 hours in thesoaking process, and immersing the mulberry cocoons again. Compared with the prior art, the mulberry cocoon preservation method has the advantages that cost input is less, technical treatment is facilitated, reelability can be improved, raw silk grade is increased, production cost is reduced, and labor tension is relieved.

Description

Technical field [0001] The invention relates to a preservation method of silkworm cocoons, in particular to a preservation method of silkworm cocoons. Background technique [0002] Due to the strong seasonality of silkworm production, the time for silkworm cocoons to form cocoons is very concentrated. It is required that the silkworm cocoon purchasing unit (cocoon station) must dry all silkworm cocoons within one week. Due to the moth phenomenon, the formed "moth cocoon" has lost its due value due to the inability to reel silk normally. After the cocoon station has invested a lot of money to purchase cocoon drying equipment (currently, the automatic cocoon drying equipment is nearly 300,000 yuan), it is generally only used twice a year (spring and autumn), and the cumulative use of it does not exceed 15 days in a year. The rate is very low. [0003] [0004] In addition, because the high temperature is used to kill the live pupae, the outer sericin of the cocoon silk will be dena...
