Embodiment 1

[0019] (1) Select a moisture analyzer with an accuracy of 0.001g, and set the temperature at 110°C;

[0020] (2) Take 5-10g of fresh cocoon raw silk sample, cut it into powder, and then put it in a device with a certain precision; record the sample weight from time 0, and then record it every 1 minute to form a sample weight sequence, and generate a curve;

[0021] (3) replace fresh cocoon raw silk with dried cocoon raw silk, and repeat step (2);

[0022] (4) Analyze the characteristics of the generated curves. If the water dispersion is fast in the initial stage and the water dispersion is slow in the final stage, it is fresh cocoon raw silk, otherwise it is dry cocoon raw silk.

Embodiment 2

[0024] In order to avoid shoddy cocoon raw silk, on the basis of the above-mentioned embodiment 1, the detection method of fresh cocoon raw silk provided by the embodiment of the present invention also includes steps:

[0025] (1) Mix 20g of powdered fresh cocoon raw silk with 1g of silicone oil, then add 30g of polyethylene powder and mix to obtain a mixture, and press the mixture into tablets 1; use a single-punch tablet machine for tableting, with a pressure of 5-6 MPa, Tablet thickness 1mm, tablet diameter 1cm;

[0026] (2) Mix 20g powdered dry cocoon raw silk with 1g silicone oil, then add 30g polyethylene powder and mix to obtain a mixture, and press the mixture into tablets 2; use a single-punch tablet machine for tablet compression, with a pressure of 5-6 MPa, Tablet thickness 1mm, tablet diameter 1cm;

[0027] (3) Carefully put the pressed tablet (for tablet 1 and tablet 2 respectively) into the circular fixture for sheet-shaped samples dedicated to the Taihe time-do...

Abstract

The invention provides a detection method for fresh cocoon and raw silk, by cutting the sample into powder and placing it on a weighing instrument, placing the weighing instrument in a moisture analyzer with target accuracy, and setting the drying temperature at intervals Record the weight of the sample in time, and sort out the sample weight change sequence after completing the data collection; wherein, the samples include fresh cocoon raw silk and dry cocoon raw silk of different varieties; generate a data map for the weight change sequence data of the collected samples, and extract the data map According to the typical characteristic changes in the sample, the sample identification is completed according to the characteristic changes. The present invention utilizes the difference in water content between the fresh cocoon raw silk and the dried cocoon raw silk to identify the fresh cocoon raw silk and the dried cocoon raw silk, and has the advantages of quickness, convenient operation, low cost, high efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a detection method of fresh cocoon and raw silk. Background technique [0002] Cocoon is the most important product of sericulture production, and it becomes the raw material of silk industry through commodity market circulation. In the process of selling silkworm cocoons as commodities, the evaluation of their quality is the basis for setting cocoon prices. The implementation of a high-quality and high-price silkworm cocoon purchase policy will help encourage silkworm farmers to adopt new varieties, new technologies, and new equipment to improve the quality of silkworm cocoons, thereby improving the quality of silk in our country. Improve product quality and enhance competitiveness in the international market. Silkworm cocoon quality inspection methods and detection technology are the technical support for the implementation of high-quality and high-price silkworm...
