The invention discloses a production technology for preparing fresh
zanthoxylum bungeanum oil by a pressing method. The production technology comprises the following steps of adding water to
zanthoxylum bungeanum raw materials, crushing a mixture of the
zanthoxylum bungeanum raw materials and the water to obtain
zanthoxylum bungeanum pulp in a physical pressing manner; adding salad oil to the
zanthoxylum bungeanum pulp, performing uniform stirring, placing the
zanthoxylum bungeanum pulp and the salad oil after being uniformly stirred into an ultrasonic wave reaction tank for soaking, and then performing separation so as to obtain water,
crude oil and zanthoxylum bungeanum cake impurities; and performing prefiltration and
settling on the
crude oil to remove zanthoxylum bungeanum dregs, and then performing rectification and separation to remove
moisture so as to obtain high-purity zanthoxylum bungeanum refined oil. According to the production technology disclosed by the invention, fresh zanthoxylum bungeanum is used as a
raw material, and a normal-temperature pressing manner is used for extracting the zanthoxylum bungeanum oil, so that the production technology of the zanthoxylum bungeanum oil is optimized, and original natural ingredients and physiological activators in the fresh zanthoxylum bungeanum can be reserved to the maximum extent. The condition that high
temperature treatment enables substances of amides,
protein and the like in volatile oil to be denatured and lost can be avoided, and the oxidative rancidity of quality of the zanthoxylum bungeanum
oil can be effectively controlled; and in the
processing technology, a cold pressing method is adopted, so that the extraction time can be shortened, and the
economic benefits of products can be increased.
