Embodiment Construction
[0028] The specific steps of negative pressure cavitation extraction of peanut resveratrol extract of the present invention are as follows:
[0029] ①Cleaning equipment: Fill the extraction tank and concentration tank with tap water (nearly full), heat to 100°C, keep warm for 1 hour, drain the water, and then wash with tap water once.
[0030] ② Preparation of extraction solvent: 95% edible alcohol and distilled water are made into 30%-90% ethanol solution.
[0031] ③ Feeding: Weigh 120 kg of peanut shells, and add 30% to 90% ethanol according to the ratio of solid to liquid of 1:8 to 15. When feeding, the material and the solvent should be put into the extraction tank step by step, and the mixer should be turned on to stir so that the material and the solvent can be fully mixed.
[0032] ④Primary extraction: After the feeding is completed, seal the extraction tank, open the pressure valve, keep the pressure in the extraction tank at -0.01~-0.1MPa, and keep the negative press...
