I WAS WONDERING HOW TO DEHYDRATE HUMAN URINE INTO POWDER FORM. I AM INTERESTED
IN STARTING A SMALL BUSINESS, AND I HAVE DONE A LOT OF RESEARCH AND ONLY FOUND
FOOD DEHYDRATORS. I HAVE SEEN DEHYDRATED URINE BEFORE SO I KNOW IT CAN BE DONE.
IS THERE A MACHINE OR PROCESS THAT CAN DO THIS FOR ME?

If dehydrating urine is your goal for the purpose of supplying it to
others as a drug testing alternative, I would suggest against it
because there are many companies which already accomplish this task,
and I'm sure have dedicated factories to mass produce it. Almost all
of these products are not real urine, even if they say real urine, but
a chemical formula made up of salts and chemicals present in urine in
the right qualities, then packaged ready for reconstitution. But if
you're just a powdered urine hobbyist, you really have only two
choices available to you without buying expensive chemical engineering
equipment. One is to collect urine in a glass jar, and let it
evaporate on its own. This will have to be done over and over again,
because the sediments collected will be a light powder on the glass,
and probably too small to collect the first run through. Do not
accerlate the process with heat, as you'll boil away some of the
consituents (at least that's what I've found on various anti-drugtest
boards). One solution I have not come across however is the use of
dessicants to accelerate the process. In this method, you would
collect urine in a glass container, and then in a larger sealed
container, put the urine container surrounded by chemical dessicant.
Usually this is silica gel (the same stuff they put in vitamin jars to
keep the pills from getting too moist). You're going to need a hefty
amount of dessicant because it can only hold so much of its own weight
before you have to heat the dessicant to evaporate off the water, or
throw it away (depending on the dessicant used). Below is a link to a
wholesaler of dessicant which will supply on request a free sample of
different dessicants so you can experiment and find out which works
best. The chemistry is sound, the dessicant sucks the water vapor out
of the air accelrating the evaporation and dehydration, without a
(substantial) change in temperature of the dessicant and/or urine
itself. Although they do not list prices, I would ask for a sample of
MIL-D-3716 or Blue Indicating MIL-D-3716 (turns pink when it can't
hold anymore water). The best setup would be to fill a gallon
tupperware container with dessicant, and then put inside it a
open-topped glass (or pyrex) jar of urine. This would probably be your
fastest recovery method of powdered urine, and I wish you the best of
luck in your endeavors.

Thank you for your question, and it was a pleasure to answer it for you.

Thankyou very much, my answer was very helpfull

The idea of using a dessicant, while feasible...would be a waste of
time and money. Those materials are meant to adsorb trace amounts of
water from the air. They would saturate in a very short amount of time
with any appreciable amount of liquid being evaporated. The best way
to do this on a commercial scale (up to 2 liters/batch) is to purcahse
a Rotary Evaporator (Rotovap). To see an explanation of how this works
go to http://www.wfu.edu/academics/chemistry/courses/organic/rotovap/Rotovap.htm
The evaporation uses low pressure (vacuum) to reduce the boiling point
of the liquid so that much less heat is required, depending on the
amount of vacuum and time that you are willing to wait water can be
removed at the rate of ~1 liter/hour at a temperature slightly over
room temperature (faster with elevated temperatures). These machines
(used) will cost on the order of $200->1000 depending on the model and
where you buy it from (new systems will be >$3000). Buchi makes a
standard model that you may be able to bid on from an outfit which
sells used lab equipment such as www.labx.com (look under the category
evaporators).
