Embodiment 1
[0034] A method for hydrolyzing silkworm cocoons with a weak base microwave, comprising the steps of:
[0035] (1) Cleaning and drying
[0036] Clean the cocoons first, then heat and dry the cocoons until the drying rate reaches 55%.
[0037] In this step, the impurities on the silkworm cocoons are preferably removed by spraying. After the impurities are removed, the silkworm cocoons are dried in the following manner. The specific drying process includes three stages: preheating, constant-speed drying and deceleration drying. In the preheating stage, a hot air tumbler is used to heat the silkworm cocoons, so that the heat energy penetrates into the cocoon cavity through the cocoon layer to kill the pupae, and the water in the pupae enters the evaporation stage; The evaporation rate on the surface of the cocoon is in a balanced state until the water diffusion rate of the pupal body gradually lags behind the evaporation rate on the surface of the cocoon layer; the deceleration...
Embodiment 2
[0046] A method for hydrolyzing silkworm cocoons with a weak base microwave, comprising the steps of:
[0047] (1) Cleaning and drying
[0048] Firstly, the silkworm cocoons are cleaned and removed, and then the silkworm cocoons are heated and dried until the drying rate is 60%.
[0049] In this step, the impurities on the silkworm cocoons are preferably removed by spraying. After the impurities are removed, the silkworm cocoons are dried in the following manner. The specific drying process includes three stages: preheating, constant-speed drying and deceleration drying. In the preheating stage, a hot air tumbler is used to heat the silkworm cocoons, so that the heat energy penetrates into the cocoon cavity through the cocoon layer to kill the pupae, and the water in the pupae enters the evaporation stage; The evaporation rate on the surface of the cocoon is in a balanced state until the water diffusion rate of the pupal body gradually lags behind the evaporation rate on the...
Embodiment 3
[0058] A method for hydrolyzing silkworm cocoons with a weak base microwave, comprising the steps of:
[0059] (1) Cleaning and drying
[0060] Clean the cocoons first, then heat and dry the cocoons until the drying rate is 58%.
[0061] In this step, the impurities on the silkworm cocoons are preferably removed by spraying. After the impurities are removed, the silkworm cocoons are dried in the following manner. The specific drying process includes three stages: preheating, constant-speed drying and deceleration drying. In the preheating stage, a hot air tumbler is used to heat the silkworm cocoons, so that the heat energy penetrates into the cocoon cavity through the cocoon layer to kill the pupae, and the water in the pupae enters the evaporation stage; The evaporation rate on the surface of the cocoon is in a balanced state until the water diffusion rate of the pupal body gradually lags behind the evaporation rate on the surface of the cocoon layer; the deceleration dryi...
