FLUID EXTRACTION PROCESS FOR NATURAL ORGANIC PRODUCTS.

摘要

A system and method to extract juices or other fluids from natural organic products such as fruits and leafy vegetables. A natural organic product pre-cooled between 42° F to 49° F is initially evacuated for about 60 seconds and then aerated for about 90 seconds using nitrogen. After repeating the evacuation and aeration one more time, the aerated product is fed to a triple auger unit where each auger rotates at a speed of approximately 80 RPM to 86 RPM. The outer covers of the augers are pre-cooled to a temperature gradient of 44° F to 47° F, and fluid extraction is maximized by feeding the extruded material back through the second and third augers. The extruded liquid is pressurized during subsequent filtration and then stored in a temperature-controlled container. Stringent temperature and pressure controls maintain the purity and nutrient strength of the liquid extract, while improving the shelf life.
