Process for extracting capsaicin crystal from dry capsium

This invention relates to technique of extract capsicine crystal from chili. The process as follows: use NaCl, NaHCO3, NaOH water solution and ethanol to compose modified ethanol solution; spray and leach capsicum stick layer from rotary infuser, the leaching solution contraflow to leach capsicum stick layer, transit spray - drip dry - spray - drip dry continuous countercurrent leaching, gain lixivium; condense the lixivium, use mobilizing agent composed by NaCl, sodium acetate and hydrochloric acid solution to blend, then use six number solvent oil to take circumfluence extraction, obtain capsicine crystal mother liquor, then takes controlled crystallization, gain high-purity capsicine crystal.
