The utility model belongs to the field of spice extraction, especially a kind of continuous countercurrent extraction device of natural spice extraction, in view of the low
solid-liquid mixing efficiency in the prior art, and volatile component serious problem of dispersing, present and propose the following scheme, it includes herringbone's extraction
pipe, the bottom fixed sleeve of extraction
pipe is equipped with condenser
pipe, one end of extraction pipe is fixedly connected with the feeding tank of intercommunication, the other end of extraction pipe is fixedly connected with the outlet
slag pipe of intercommunication, the lower fixed mounting of outlet
slag pipe is equipped with collection tank, in the utility model, through
motor drive gear rack meshing, reciprocating movement is promoted
piston, dynamic
extrusion is carried out to spice, so that the particle size of spice is less than 2mm, prevent the non-uniformity of particle size during transfer and produce accumulation, improve
solid-liquid mixing efficiency, furthermore, through the cooling water of 15-25 ℃ from condenser pipe circulation, through pipe wall exchange heat, maintain the temperature constant in extraction pipe, prevent heat-sensitive component volatilization.
