Problems solved by technology

However, the refrigeration and preservation method provided by this technology requires the use of large refrigerators, and requires the freezing temperature to be maintained at -12 to -6°C for a long time, which requires high equipment conditions and consumes a lot of energy. The quality has adverse effects, which is not conducive to the long-term storage of cocoons

Embodiment 1

[0029] The specific technical process of the storage and preservation method of silkworm fresh cocoons of the present invention is as follows: figure 1 As shown, it specifically includes the following steps:

[0030] (1) Screening fresh cocoons: The fresh cocoons of silkworms purchased, such as castor cocoons and tussah cocoons, are manually selected to remove secondary cocoons such as dead cage cocoons, double palace cocoons, and fly cocoons, so as to avoid contamination of upper and middle cocoon fresh cocoons during storage. cocoon.

[0031] (2) Lay the dry ice taken out from the dry ice container on the assembly line, the dry ice layer is 0.5cm; then put the fresh cocoons screened through the above steps, the thickness of the fresh cocoon layer is 1cm, and then spread the fresh cocoon layer on the fresh cocoon layer with a thickness of 2cm The dry ice layer forms a layer-by-layer structure, that is, a sandwich pattern; the assembly line moves forward, and the silkworm chr...

Embodiment 2

[0036] In the step (1) of the embodiment, the fresh cocoon of one deck 2cm is spread again on the dry ice of the second layer, and the dry ice thick of 4cm is spread on the fresh cocoon layer again, and other steps are with embodiment (1).

Embodiment 3

[0038] The specific technical process of the storage and preservation method of silkworm fresh cocoons of the present invention is as follows: figure 1 As shown, it specifically includes the following steps:

[0039] (1) Screening fresh cocoons: The fresh cocoons of silkworms purchased, such as castor cocoons and tussah cocoons, are manually selected to remove secondary cocoons such as dead cage cocoons, double palace cocoons, and fly cocoons, so as to avoid contamination of upper and middle cocoon fresh cocoons during storage. cocoon.

[0040] (2) Lay the dry ice taken out from the dry ice container on the assembly line, the dry ice layer is 2cm; then put the fresh cocoons screened through the above steps, the thickness of the fresh cocoon layer is 4cm, and then spread the fresh cocoon layer with a thickness of 4cm on the fresh cocoon layer The dry ice layer forms a layer-by-layer structure, that is, a sandwich pattern; the assembly line moves forward and lasts for 15 to 20 ...

Abstract

The invention provides a storage fresh-keeping method for a silkworm fresh cocoon; silkworm chrysalis inside the fresh cocoons are killed by the quick freezing of dry ices; the fresh cocoons with the chrysalis killed are arranged in a closed article where the air is pumped out and the dry ices are added and the dry ices are converted into the CO2 gas under normal temperature; the fresh cocoons are hermetically stored under the anaerobic condition. The storage fresh-keeping method can keep the natural state of the cocoons better, has little effect on the silk quality, has simple, sanitary and convenient operation, quick disposal speed and low processing cost, can improve the silk generation rate and the silk generation quality; after reeling silk, the fresh cocoons can be taken as the raw material of the deep processing and is suitable for popularization and application in large scale.

Description

technical field [0001] The invention relates to a processing technology for silkworm fresh cocoons, in particular to a storage and preservation method for storing silkworm fresh cocoons at room temperature by using carbon dioxide gas after killing pupae with dry ice. Background technique [0002] After the fresh cocoons of silkworms (including castor silkworms and tussah silkworms, etc.) are purchased, they are generally baked into dry cocoons in a coal stove, and stored in a cocoon warehouse at room temperature for cocoon cooking, silk reeling and silkworm chrysalis processing. This is a traditional craft for decades. technical route. The process of baking silkworm cocoons and silkworm chrysalis at 105-110°C for 6-8 hours will cause the denaturation of cocoon sericin protein and silkworm chrysalis protein. Fatty acids such as chrysalis oil will become rancid due to oxidation, resulting in foreign matter, which will affect further processing. Fresh cocoons are baked at high...
