What is Freeze Drying? How Does it Work? Millrock
Freeze drying (also known as lyophilization) is a water removal process typically used to preserve perishable materials, with the goal of extending their shelf life and/or preparing them for transport.Freeze drying works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimate).

Understanding The Dry Granulation Process
The original method of dry granulation employed a heavy duty tablet press to compact the dry powder. The compacting process in this case is known as slugging and the compacted material was therefore in the form of "slugs" - typically 25 mm in diameter and 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create granules.

Bead Milling
Bead Mills are machines for dispersion processing, where solid particles (pigments, fillers) are reduced in size and finely dispersed and wetted out in a liquid phase. Small ceramic, glass or metal beads are agitated inside the mill chamber to aid particle size reduction through impact and energy input while the dispersion is pumped through the mill.

Ethanol Production
While dry milling is less capital intensive, it also yields less ethanol per bushel of corn than wet milling (Rajagopalan, et al., 2005). Wet milling involves steeping the corn for up to 48 hours to assist in separating the parts of the corn kernel. Processing the slurry separates the germ from the rest of the kernel, which is processed further
