Systems and methods for preparing wax and lipid particles
First Claim
1. A system for forming particles, the system comprising:
- a conduit with a lumen having a first cross-sectional dimension and having an inlet and an outlet;
an extruder having an inlet and an extruder orifice as an outlet located within the conduit, the extruder orifice having a second cross-sectional dimension that is smaller than the first cross-sectional dimension;
a carrier fluid reservoir fluidly coupled with the conduit inlet;
an extruder reservoir fluidly coupled with the extruder inlet;
a particle collector fluidly coupled with the conduit outlet, wherein the particle collector has a collector inlet with a first temperature and a collector outlet with a second temperature that is lower than the first temperature with a temperature gradient between the first temperature and second temperature, wherein the collector inlet is coupled with the conduit outlet and the collector outlet is opposite of the collector inlet with a particle collector chamber between the collector inlet and collector outlet;
the particle selector having a waste outlet opposite of the collector inlet; and
a particle selector in the particle collector, wherein the particle selector is configured to direct particles to the collector outlet or the waste outlet.

Abstract
The system can include: a conduit having a first dimension with an inlet and outlet; an extruder having an inlet and an outlet located within the conduit, an extruder orifice having a second dimension that is smaller than the first dimension; a carrier fluid reservoir coupled with the conduit inlet; an extruder reservoir coupled with the extruder inlet; and a particle collector fluidly coupled with the conduit outlet, wherein the particle collector has a collector inlet with a first temperature and a collector outlet with a second temperature. The method can include flowing carrier fluid through the extrudate conduit; extruding wax with the extruder into the carrier fluid that is flowing through the extrudate conduit such that the extrudate separates into extrudate segments separated from each other by carrier fluid segments; and flowing the extrudate into the particle collector so as to form wax particles.
