The invention provides a preparation method of
aromatherapy lacquer wax, which comprises the following steps: S1, taking dried
lacquer tree seeds, carrying out peel-kernel separation, and crushing
lacquer seed peels by using a
crusher; s2, mixing the crushed lacquer seed peels with the pretreated
plant aromatherapy raw materials, and performing low-temperature
granulation; and S3, putting the granulated mixed
raw material into a supercritical CO2 extraction device, carrying out continuous supercritical CO2 extraction, and analyzing by a separation kettle to obtain the
aromatherapy lacquer
wax. According to the preparation method of the aromatherapy lacquer
wax, the lacquer seed peels are crushed and then fully mixed with the
plant aromatherapy raw materials according to the proportion, low-temperature
granulation is performed, and then low-temperature continuous supercritical CO2 continuous extraction is performed to prepare the aromatherapy lacquer wax, so that the production temperature is low, the
plant fragrance is fully reserved, meanwhile, the
energy consumption is effectively reduced, the production efficiency is improved, and the production cost is reduced. The prepared aromatherapy lacquer wax is rich in fragrance, and the fragrance emission time is prolonged.
