The invention discloses a processing technology of vinegar-processed corydalis rhizoma, and relates to the field of orydalis rhizoma processing. The vinegar-processed corydalis rhizoma is processed through the steps of material selection, hair removal, cleaning, addition of sodium bicarbonate for soaking and cleaning, slicing, refrigeration, air drying, addition of vinegar for stirring, sealed soaking, addition of water, cooking, drying, air cooling and the like. According to the processing technology, fibrous roots of the corydalis rhizoma are removed, then the corydalis rhizoma is put into acleaning system, sodium bicarbonate is added for soaking and cleaning, so that the corydalis rhizoma is thoroughly cleaned, the vinegar corydalis rhizoma is good in color, the situation that the effects of enhancing and pain relieving cannot be achieved due to the fact that the vinegar absorption of the corydalis rhizoma is affected by surface dirt is avoided, a soaking barrel, a cleaning barreland a rotating shaft are arranged to rotate along with a water flow plate under the impact flowing effect of water to drive a five-foot brush to rotate, the sodium bicarbonate decontamination effect is fully achieved, meanwhile, the five-foot brush brushes the corydalis rhizoma and stirs a mixture in the cleaning barrel, the clean corydalis rhizoma is subjected to an environment from low temperature to normal temperature, internal loose holes are increased, the absorption rate of vinegar is increased, and the pain relieving effect is enhanced.
