The invention belongs to the field of
animal oil extractive techniques, and particularly provides a
snake oil refining method. The method includes the following steps: step 1, heating and refining the
raw material of
adipose tissue of snakes to obtain
refinery liquor, and filtering the
refinery liquor while the
refinery liquor is hot to obtain filter liquor as main sake oil liquor, step 2, squeezing residual filter residues to obtain squeezed liquor, and filtering the squeezed liquor to obtain filter liquor as
snake oil contained in the filter residues, step 3, mixing the main sake oil liquor with the
snake oil contained in the filter residues to obtain a crude snake oil product, and step 4, dissolving the crude snake oil product into an
organic solvent to carry out extraction repeatedly, carrying out extraction in ultrasonic
waves, recycling the
solvent in a
distillation method, and filling
nitrogen into the
solvent to obtain refined snake oil. The technique is simple in operation and low in requirement for equipment, the color of the prepared product is light, snake
oil can be completely extracted, the use ratio of the
raw material is higher than that in a traditional technique, time for high-temperature snake oil refining is shortened, the content of
active components in the refined snake oil is high, and the refined oil sake can exert functions quickly and better. Industrial output is improved, and significant social and
economic benefits are achieved.
