[Gasification] Biofiber drying quantification

[Hararat]

In 1998 I began developing a process called the UGDFS (Ultra Gravity Dry Fractionation System).  It uses coaxial boundary layer tevchnology to accelerate the slurries.  The water is stripped off into the boundary layer.  This process required little heating and there was some shearing effect happening at the boundary layer.  Deomnstrations can be seen on video.
I used this to try to dry chicken manure in 2000 for 1,000,000 layer hens in Neosho, Missouri for Moark Productions.  They own the patent rights now and may be contacted for further development information.  We suffered from plugging at the primary cyclone and I abandoned the process.  Several others are similarly trying to accomplish the same with the coaxial boundary layer phenomenon.  Terra Systems of Spanish Fork, Utah may have had success by now.
The problem of lysing the cell walls was overcome by cenrtifigation as EIMCO (Hughes, Houston) were developing this in the UK.  In our process we used a coaxial flow cyclone.  The pressure developed on the cell walls was enough to implode them, hence releasing the moisture for adsorption into the boundary layer.  Others have tried high pressure, pressure vessels (100,000 psig) for the purification of orange juice.  This has been a batch process.
