FIELD: process engineering.
SUBSTANCE: set of inventions relates to method and device for primary processing material being transferred, revolved, mixed, heated or minced by, at least, one mixer 12, 21 in intake tank or cutting compressor 1. Undesirable impurities that may interfere with primary or subsequent processing are removed. Note here that mixing vortex is produced in zone located under the level of material in intake tank 1. Gas, e.g. air or inert gas, is fed into said tank. Said gas is forced through, at least, portion of material. Note also that gas enriched or saturated with impurities above material in tank 1 or that in mixing vortex is discharged from tank 1.
EFFECT: equal temperatures and uniform pre-compaction, uniform processing at extruder outlet.
