<DIV><FONT face=Arial size=2>Hi Matt,</FONT></DIV>
<DIV><FONT face=Arial size=2>In response to your request for information on
drying digestate, please find the following details which work for
me.</FONT></DIV>
<DIV><FONT face=Arial size=2>The digestate contains several substances which are
of great benefit to crops, the soil and much more. Once you are familiar with
the fallacy of NPK, you will come to realize the value of recycling plant
nutrient via digestion.</FONT></DIV>
<DIV><FONT face=Arial size=2>The liquid fraction is made up of fulvic acid and
colloidal minerals which are immediately available to plants as they are
originally derived from plants. Diluted similarly to seaweed concentrate, this
colloidal solution is applied directly to the foliar aspects of the plant where
it is directly absorbed via the stomata.</FONT></DIV>
<DIV><FONT face=Arial size=2>The solid fraction is rich in carbon
compounds and non-colloidal minerals ideally suited to soils. When
converted to pellet form and suitably dried, this material is able to be applied
using standard broadcasting techniques. This material, while still in a wet
form is able to have liquid or dry ingredients added before pelleting to correct
measured soil deficiencies. </FONT></DIV>
<DIV><FONT face=Arial size=2>Below this solid fraction copious amounts of fiber
is found. This fiber is not degraded by the bacteria of the bio-reactor,
nor is it consumed by vermiculture. Fiber is not digested by any organism other
than fungus.</FONT></DIV>
<DIV><FONT face=Arial size=2>This fiber is able to be mixed with the carbon
compounds previously mentioned and bound up as a pellet, or separated out
and directed to paper making, or the manufacture of carbon fiber.</FONT></DIV>
<DIV><FONT face=Arial size=2>Before all this is done, the digestate needs to be
segregated into these separate substances. I use vibro-filtration through
several different sized screens, then centrifuge to isolate colloidal
materials from carbon compounds.</FONT></DIV>
<DIV><FONT face=Arial size=2>The use of potassium hydroxide also enables the
dissociation of fulvic acid from more dense humic substances.</FONT></DIV>
