Example Embodiment
[0032] Example 1
[0033] Take 100L of coenzyme Q10 fermentation broth (fermentation unit 2900u / ml), filter it into ceramic membrane microfiltration membrane (pore size 0.1um), feed temperature about 25℃, dialysis ratio 1:1.5, concentration factor 1.8 times, and obtain membrane slurry 139L ( The potency is 2050u / ml), and the yield is 98.18%.
[0034] The above membrane slurry was spray-dried, and the inlet air temperature was controlled to 140-160°C and the outlet air temperature was 60-70°C to obtain 307 g of Coenzyme Q10 crude product, with a moisture content of 9.2% and a yield of 97.90%.
[0035] Dry the above spray to obtain the crude product, add it to the distiller, add 3 times the volume of the crude product weight of acetone (921ml), add 0.5‰ (w / v) zeolite, slowly raise the temperature to 49℃, reflux for 2.0hr, then pass the ceramic The filter element filter (pore size 0.5um), the filter residue is leached again, and the leaching conditions remain unchanged. Collect the ex...
