[0027] Take fresh wet silkworm chrysalis from the silk reeling factory, remove dead silkworms, dead silkworms, bad chrysalis and other fiber impurities, weigh 100 kg, and carry out mechanical crushing; add the crushed materials to a dilute alkali solution in a ratio of 1:16 to dissolve, dilute The pH value of the alkaline solution is 9 to 11, the temperature is 60 to 70°C, and the dissolution time is 50 to 70 minutes;
[0028] Filter with a stainless steel mesh of about 50 meshes to remove the pupal shells; separate the filtered solution with a solid-liquid two-stage butterfly separator to remove residual pupa shells and non-water-soluble impurities in the solution; then use liquid-liquid-solid The three-phase butterfly separator separates the oil in the silkworm chrysalis protein solution;
[0029] Filter the separated protein solution with a ceramic membrane with a pore size of 2000Da, and the filtered NaOH dilute alkali solution can be recycled.
[0030] Warm the protein s...
