Embodiment 1
[0016] Select an ultraviolet light source lamp with an emission wavelength of 300 to 380 nanometers and an ultraviolet light-transmitting glass in this wavelength range to form a simple fluorescent detection device for male and female cocoons of silkworms. According to the characteristics of the silkworm cocoon: female cocoon purple fluorescence, male cocoon white fluorescence or female cocoon white fluorescence, male cocoon yellow fluorescence or female cocoon purple fluorescence, male cocoon yellow fluorescence, perform fluorescence judgment, and separate female and male cocoons .
[0017] The size and thickness of the cocoon layer of the female and male silkworm cocoons were measured respectively. Referring to the conventional cocoon drying process, the cocoon drying process conditions were adjusted as follows: when drying the female cocoons, reduce the constant-speed drying temperature by 3-10°C, and shorten the deceleration drying time by 0.5°C. ~3.5 hours; for male cocoo...
