[0030] The preparation method of composite sedimentation component A includes the following steps:
[0031] (1) Take the narcomontmorillonite, acrylamide, and water mixture according to the mass ratio of 1:5~8:25, move to an ultrasonic oscillator and treat with 50~65kHz ultrasonic wave for 12~20min to obtain the dispersion, and put it in a water bath for 35~ At 45℃, take the dispersion liquid and add surfactant and stearyl acrylate with a mass ratio of 8~15:1:1~3, protect by nitrogen, heat up to 55~70℃, add 1~4% of the dispersion liquid Sodium persulfate, magnetically stirred at 500~800r / min for 35~60min to obtain the reaction material;
[0032] (2) Take the pre-treated brewer’s grains, tea polyphenols, and water at a mass ratio of 1:2:15~25 and mix them with a magnetic force of 700~1000r / min for 40~60min to obtain a mixture. In parts by weight, take 4 ~8 parts of lecithin, 12~20 parts of reaction material, 2~5 parts of glutaraldehyde, 20~30 parts of mixture, 7~15 parts of gelatin...

[0035] Example 1
[0036] Pretreatment of brewer's grains: After washing the brewer's grains with water twice, drying in an oven at 55°C for 2h, transfer to a grinder to smash through a 120-mesh sieve, take the sieved particles and add 50% nitric acid solution with a mass fraction of 1:4 Mix, stir at 400r / min for 35min, add water to adjust the pH to 6.8, filter, take the filter residue and mix with triethyl citrate at a mass ratio of 8:1 to obtain pretreated beer lees.
[0037] Gelatin liquid: Mix gelatin, aniline, and water at a mass ratio of 1:0.3:20 at 40°C, and stir at 500r / min for 35 minutes to obtain a gelatin liquid.
[0038] Surfactant: Mix sodium dodecylbenzene sulfonate and cetyltrimethylammonium bromide at a mass ratio of 4:1 to obtain a surfactant.
[0039] Excipients: Mix polyvinylpyrrolidone, microcrystalline paraffin, and dodecyl dimethyl benzyl ammonium chloride at a mass ratio of 3: 1: 5 to obtain auxiliary materials.
[0040] Additives: take a 37% formaldehyde solutio...
