US 2026/0158091 A1 · SYSTEMS AND TECHNIQUES FOR EXTRACTING HEMP SEED OIL

Abstract

Systems and techniques are provided for processing a high oil concentration feedstock, particularly a hemp feedstock, to extract oil from the feedstock. In some examples, the feedstock is processed by flaking the hemp feedstock followed by solvent extraction. The hemp material may be introduced between rotating flaking rolls to flake the hemp heart feedstock. According to some examples, the speed and/or spacing of the flaking rolls may be controlled to control the characteristics of the resulting flaked hemp material for subsequent solvent extraction. Extraction performance of the hemp feedstock can vary based on the characteristics of the flake properties dictated by controlling the flaking rolls.

Dependent claims

A method comprising:

flaking a hemp material by passing the hemp material through a pair of rotating flaking rolls defining a nip clearance between the rotating flaking rolls within a range from 0.2 mm to 0.32 mm, thereby producing a flaked hemp material having a mean thickness within a range from 0.25 to 0.65 mm;
introducing the flaked hemp material into an extractor and contacting the flaked hemp material with a solvent, thereby producing an extracted hemp material and a miscella;
and
separating the solvent from the miscella, thereby producing an extracted hemp oil.
