Problems solved by technology

Due to the difference in the silkworm's body constitution and cocooning environment, as well as the impact of storage and transportation, the quality of fresh cocoons at the beginning of entering the silk reeling factory is uneven, and there will be dirt such as yellow spots, oil stains and dust. It needs to be rinsed and decontaminated before production. The existing silk production process decontaminates fresh cocoons while cocoons are boiled. If there are too many stains on fresh cocoons, the stains produced by cocoons can easily reattach to the cocoon surface under the action of high temperature.

Embodiment 1

[0018] A method for rinsing and decontamination of fresh cocoons includes the following steps:

[0019] A. Cocoon selection: Rough selection of fresh cocoons, remove secondary cocoons and lower cocoons that cannot be produced, and obtain qualified fresh cocoons suitable for production;

[0020] B. Classification: separate the qualified fresh cocoons obtained in step A according to their size and serious dirt procedures;

[0021] C. Vibration once: use a vibrating screen to vibrate the fresh cocoons classified in step B for 2 minutes;

[0022] D. One-time baking: baking the fresh cocoons after one vibration in step C, the baking time is 3 minutes, so that the water absorption rate of the fresh cocoons can reach more than 90%;

[0023] E. Secondary vibration: use a vibrating screen to vibrate the fresh cocoons baked in step D for 2 minutes;

[0024] F. Soaking: Put the fresh cocoons after the second vibration in step E into a mixed solution containing 0.3% surfactant and 0.1% penetrant. Th...

Abstract

The invention discloses a method for rinsing and decontaminating green cocoons and relates to the technical field of silkworm cocoon processing. The method comprises the following steps: A, selecting cocoons; B, classifying; C, performing primary vibration; D, performing primary baking; E, performing secondary vibration; F, soaking; G, cleaning and performing secondary baking. Compared with the prior art, the method for rinsing and decontaminating green cocoons provided by the invention has the advantage that stains of the green cocoons can be completely cleaned.

Description

Technical field [0001] The invention relates to the technical field of silkworm cocoon processing, in particular to a rinsing and decontamination method for fresh cocoons. Background technique [0002] Fresh cocoons refer to silkworm cocoons that have been purchased from silkworm farmers and have not been dried. Specifically, they refer to silkworm cocoons that have not been pupa-dried. In the process of making silkworm cocoons into silk, the first step is to process fresh cocoons. Due to the differences in the body constitution and cocoon formation environment of silkworms, as well as the impact of storage and transportation, the quality of fresh cocoons at the beginning of entering the silk reeling plant is uneven, and there will be stains such as macula, oil stains and dust. It needs to be rinsed and decontaminated before production. The existing silk production process performs fresh cocoon decontamination while cooking the cocoon. If the fresh cocoon stains too much, the st...
