[0021] The preparation method using this device specifically includes the following steps:
[0022] It includes the following steps:
[0023] step one
[0024] After removing impurities, the donkey skin is soaked at 30-60℃ for 3-5 days under water sealing conditions; after shaving, crushing and washing, according to the mass ratio, water: donkey skin = 4-6:1, preferably 5:1 ; Add water to the donkey skin prepared, after adding water, under sealed conditions, heat to 100-120°C, preferably 105-120°C; stir and extract for 15-20 hours; release the liquid to obtain the first liquid, container Remaining residue inside; add water to the remaining residue, under sealed conditions, heat to 105-120℃; stir and extract for 15-20 hours, release the liquid to obtain the second liquid; after adding water, the filling rate of the container is 40-50 %;
[0025] Step two
[0026] The first liquid and the second liquid are coarsely filtered, then finely filtered, and after finely filtered, vacuum conce...
Embodiment 1
[0045] step one
[0046] After removing impurities from the donkey skin, soak it at 30°C for 3 days under water-sealed conditions; after dehairing, crushing and washing, according to the mass ratio, water: donkey skin = 5:1; add water to the donkey skin prepared, and add water Then, under sealed conditions, heat to 105°C; stir and extract for 18 hours; release the liquid to obtain the first liquid with residue remaining in the container; add water to the remaining residue, and heat to 120°C under sealed conditions; stir; Extract for 15 hours, release the liquid to obtain the second liquid; after adding water, the filling rate of the container is 45%;
[0047] Detect the content of organic matter in the residual material, the test result is: the content of organic matter is less than 2.5%.
[0048] Step two
[0049] According to the volume ratio, the first liquid: the second liquid = 1:1 mixed, then coarse filtration, then fine filtration, and after fine filtration, vacuum concentrati...
Embodiment 2
[0061] step one
[0062] After removing the donkey skin, it will be fermented at 30°C for 5 days under water-sealed conditions; after dehairing, crushing and washing, according to the mass ratio, water: donkey skin=5:1; add water to the donkey skin prepared, add water Then, under sealed conditions, heat to 118°C; stir and extract for 15 hours; release the liquid to obtain the first liquid with residue remaining in the container; add water to the remaining residue, and heat to 120°C under sealed conditions; stir; Extract for 15 hours, release the liquid to obtain the second liquid; after adding water, the filling rate of the container is 48%;
[0063] Detect the content of organic matter in the residual material, the test result is: the content of organic matter is less than 2%.
[0064] Step two
[0065] According to the volume ratio, the first liquid: the second liquid = 2:1 mixed, then coarse filtration, fine filtration, and vacuum concentration after fine filtration; a gel with a ...
