Problems solved by technology

[0003] However, due to the strong seasonality of silkworm production, the cocooning time of silkworm cocoons is very concentrated, so it is required that the silkworm cocoon purchasing unit (cocoon station) must complete the high-temperature drying of all silkworm cocoons within 1 week, otherwise it will be destroyed. Moth phenomenon occurs, forming "moth mouth cocoon", because "moth mouth cocoon" cannot be reeled normally, it loses its due value
It can be seen that the automatic cocoon drying equipment used in the cocoon station is generally only used twice a year (spring and autumn), and the accumulated use does not exceed 15 days a year, so the utilization rate is very low; at the same time, the price of this automatic cocoon drying equipment is relatively low. High (at present,

Embodiment 1

[0022] A method for refrigerated storage of silkworm cocoons, comprising the steps of:

[0023] (1) Materials and equipment: The mulberry silkworm species tested is Jingsong×Haoyue, and the refrigerated container is a cold storage (with a volume of 30m 3 );

[0024] (2) Cocoon picking: collect silkworm cocoons 7 days after silkworms go up to the stack, select bad cocoons, put them flat in a refrigerator, and it is advisable not to exceed 5 cocoons vertically;

[0025] (3) Refrigeration: adjust the temperature of the cold storage to 12°C, adjust the humidity to 60-65% to buffer the silkworm cocoons in the warehouse, and after the silkworm cocoons are put into storage for 24 hours, the temperature drops to 6°C, the humidity is adjusted to 65-70%, and the shading Protect;

[0026] (4) Sampling survey: after the silkworm cocoons are stored in the warehouse, take samples once in two days in the first 10 days, and take samples every 5 days after 10 days to observe the development ...

Embodiment 2

[0031] A method for refrigerated storage of silkworm cocoons, comprising the steps of:

[0032] (1) Materials and equipment: The mulberry silkworm species tested is Jingsong × Haoyue, and the refrigerated container is a cold storage;

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 [0001] The invention relates to a storage method, in particular to a method for storing silkworm cocoons. Background technique [0002] Silkworm (Bombyx mori L.) has been domesticated in my country for more than 5,700 years. It belongs to the complete metamorphosis insect of Lepidoptera Bombyridae, and its generations include egg, larva, pupa and adult (moth). The larva spins silk and forms a cocoon in the later stage, and pupates in the cocoon, and the pupal period is about 15 days. In order to obtain complete cocoons, the traditional craft is to collect the formed cocoons and use high-temperature baking to kill the live pupae in the cocoons, so as to achieve the purpose of long-term preservation of silkworm cocoons and provide raw cocoons for the silk reeling industry. [0003] However, due to the strong seasonality of silkworm production, the cocooning time of silkworm cocoons is very concentrated, so it is required that the silkworm cocoon purchasing uni...
