ABSTRACT:
An apparatus for extraction of uncontaminated aloe vera gel from the leaves of aloe vera plants. The harvested leaves of the aloe vera plants are positioned between a pair of endless moving belts for passing by a plurality of crushing rollers arranged in a desired pattern. The rollers first crush the core of the leaf to enable the gel to flow internally while a second set of rollers extrudes the gel from the leaf. The crushed leaf and extruded gel is then deposited on a drain grate to enable gravity flow separation of the gel from the crushed leaves. The drainage grate is sloped in order that the leaves will slowly move across the drain grate to enable separation of the gel while removing the leaf from the gel collection area prior to the flowing of the contaminate aloin from the leaf.
