A method for efficiently removing non-magnetic foreign material, from a carbonaceous material dispersion in which carbonaceous material particles are dispersed in a dispersing medium, includes applying the dispersion to a primary filter a specified number of times in circulation, the primary filter including at least one filter device; and applying the dispersion treated with the primary filter to a secondary filter a single time, the secondary filter including at least two filter devices arranged in series. Each respective filter device to be used satisfying following conditions: (a) a variation of cumulative undersize distribution Q [%] with respect to a reference particle diameter and a variation of non-volatile content, before and after passing the carbonaceous material dispersion, being not more than 0.1%, respectively; and (b) a removal rate of particles with a threshold particle diameter being not less than 20%.

Disclosed is an apparatus and method used to isolate organic acid forms of cannabinoids from a source biomass. This includes the use of a continuous, flow driven, biomass agitation unit, referred to herein as the Continuous Trichome Separator (CTS) Unit. Biomass is fed into the CTS Unit, where trichomes are shaken off of the biomass, and a mixture of trichomes and fluid continue for further processing. The trichomes are melted and then separated using chromatographic separation techniques. Thereafter the organic acids are dehydrated and become isolate compounds.
