Embodiment 1
[0035] Take by weighing 10kg royal jelly slag, add 10kg (95%) edible alcohol and stir to dissolve, then add 6.67kg of purified water and continue to stir and dissolve, cross 120 mesh nylon sieves, with the method of scraping and filtering, the filtrate is passed through 6 magnetic cups to absorb foreign matter ( The magnetic force of the magnetic holder is ≥7000 Gauss), and the obtained filtrate continues to pass through a 200-mesh nylon screen, and the filtrate is passed through 6 magnetic holders to absorb foreign matter (the magnetic force of the magnetic holder is ≥7000 Gauss), and the filtrate is obtained. Add 10kg of purified water to it, and carry out rotary evaporation and concentration at 45°C and 0.09MPa until the evaporated liquid is free of ethanol. Pour out the material, rinse the inner wall with water and incorporate it into the material, and place it in a 0-5°C freezer for storage. Overnight, take out material, pass through 400 mesh screens, the upper part of the...
Embodiment 2
[0037] Take by weighing 10kg royal jelly slag, add 10kg (95%) edible alcohol and stir to dissolve, then add 10kg purified water and continue to stir and dissolve, cross 120 mesh nylon sieves, with the method of scraping and filtering, filtrate is passed through 6 magnetic cups to absorb foreign matter (magnetic magnetic force ≥ 7000 gauss), the resulting filtrate continues to pass through a 200-mesh nylon screen, and the filtrate is then passed through 6 magnetic holding hands to absorb foreign matter (magnetic holding force ≥ 7000 gauss), and the filtrate is poured into the filtrate Add 10kg of purified water, carry out rotary evaporation and concentration at 45°C and 0.09MPa, until the evaporated liquid is free of ethanol, pour out the material, rinse the inner wall with water and put it into the material, put it in a cold storage at 0-5°C, and store it overnight , take out the material, pass through a 400-mesh sieve, the upper part of the sieve is purified pulp, and the coll...
Embodiment 3
[0039] Take by weighing 10kg royal jelly slag, add 10kg (95%) edible alcohol stirring and dissolving, add 8.6kg purified water and continue stirring and dissolving, cross 120 order nylon screens, with the method for scraping and filtering, filtrate is passed through 6 magnetic cups to absorb foreign matter (magnetic magnetic force ≥ 7000 gauss), the obtained filtrate continues to pass through a 200-mesh nylon screen, and the filtrate is then passed through 6 magnetic holding hands to absorb foreign matter (magnetic holding force ≥ 7000 gauss), and the obtained filtrate is purified by adding 20kg of water Water, stir and mix, store in 0-5°C cold storage overnight, take out the material, pass through a 400-mesh screen, the upper part of the screen is available pulp residue, which contains a small amount of ethanol, rinse with water repeatedly until there is no ethanol smell, 8.67 kg of refined pulp residues were obtained. See Figure 4 .
