摘要

PURPOSE: A facility for automatically manufacturing natural dyes is provided to obtain stable quality and to reduce labor force by automatically manufacturing polygonum indigo, Isatis japonica, and indigofera. CONSTITUTION: A facility for automatically manufacturing natural dyes comprises: an extractor(1) which extracts indigo pigments form indigo plants by supplying warm water of a room temperature to a material collector(11); a calcium hydroxide supernatant preparation device(2) which obtains high concentration calcium hydroxide supernatant by mixing water with calcium hydroxide and discharged a precipitate to the outside; an oxidation precipitation device(3) which oxidizes and precipitates indigo pigments; an indigo bath(4) for storing indigo precipitated in the oxidation precipitation device; and a control device(5).
