摘要： An improved method and apparatus for extracting resin from plant material. Conventionally, plant resins, which are useful in many products, are extracted using chemical solvents, which may alter the extract, and may produce a byproduct or residue that may be unusable or problematic. The present invention overcomes these drawbacks by using cold water in a wash process to cause the resins to become brittle, while the remaining plant material becomes more flexible. Separation is accomplished using an extractor (10) having a washing chamber (12) with an open top (14) and a screen filter (16) disposed above a settling chamber (18). A collection bottle (24) is placed below a valve (22), and may include a filter (26) to separate resin particles from the solute. The washing chamber is first filled with cold water and then a quantity of plant material (P) is placed therein, followed by an ice layer (30). An agitator (32) is then actuated to mix the contents to separate the resins. The settled resin is thereafter captured by the filter (26) upon opening the valve (22).
