The
centrifuge alone can not remove glycerin from vegetable oil.
Removing
glycerin from vegetable oil can only be done by a chemical
process.
This
process is known as "transesterfication" (trans-ester-fication).
You must
use a pre-mix of methanol and a catalyst such as sodium
hydroxide or potassium hydroxide, measured precisely and
blended with the oil for a determined period of time.
The
reaction that takes place will cause heavy glycerin to
settle where it can be drained off.
A
centrifuge can then be used to remove large portion of the
liter free glycerin that still remains suspended in the
oil after the "transesterfication" process.
Question: I'm running it from my truck on site. Is there a DC
motor solution?
Answer) Generally all DC/ 12volt motors are limited to 30
minute duty cycle by the nature of the motor. They get too hot
to run. The use of a 115 volt motor with an inverter that will
take the output of the vehicle alternator and turn it into 115
volts is recommended. We have been told but not confirmed that
some electric motor types have problems starting on inverter
power. We have had customers that have built mobile systems
but none have given us all the details that we can pass on. I
suggest using the Biodiesel info pop at:

Question:
Im about to start a Biodiesel operation. I will be filtering
1000 gal of veg oil per month this will most likely grow to
5000 gals per month within the year. Would the OC-50
centrifuge be up to this since it would operate for 9.5 hrs to
complete filtration? What product would you suggest for my
application?
Answer:
The OC-50 is
the best centrifuge for any application that has a small start
up budget but needs the ability to grow in the future.
Oil must be heated to a temperature of 140-180 F. Oil also
needs to be turned over three times on the average to assure
cleanliness. This will all depend on the oil and how you
pre-screen it. One pass is not realistic and 10 passes is over
kill. Generally 2-5 passes does it.
Here are some
options.
Project how
many gallons per day is your goal in one year?
By investing
today in a pump and motor that can pump that projected number
you then can budget and add centrifuges as you grow.
Example 1:
Buy a pump today that will move 8 Gallons per Minute/ 480
Gallons per Hour. Cost $1125 plus one centrifuge@ $499. Total
$1624
You can today
run one centrifuge that will process 108 gallons per hour. So
in 8 hours and one centrifuge you will be able to clean 288
gallons per day based on three passes through the centrifuge.
288 gallons per day will give you 6300 gallons per month.
You then can
add as many as four centrifuges as you grow. Price $499 each.
With four
centrifuges you can clean 432 Gallons per Hour. Based on that
432 GPH you could then in an 8 hour day clean 1100 gallons
which translates into 24,200 gallons per month.
Example2: Buy
one centrifuge @ $499 and one matching pump and motor @$549.
Total price $1048 and you then can process the same 288
gallons per day. As you grow you will need to add this same
package for each increase of 288 gallons per day you want to
process.
OC-50 and
OC-200 performance, differences and suggestions.
The OC-50:
-
Runs at approx 8,000 RPM at 90 PSI.
-
It holds 20 ounces of solid and water
contamination mix.
-
It processes 1.8 gallons per minute
-
Cost is $499
-
Includes mounting plate and control valve.
The OC-200:
-
Runs at 4,500 RPM at 90 PSI.
-
It holds 84 ounces of solid and water
contamination mix.
-
It processes 5 gallons per minute
-
Cost is $1550
-
Includes control valve only
In both cases the centrifuge will remove water.
-
The oil, either waist vegetable oil or motor
oil, must be heated to a minimum of 140F. 180F if optimum
and 205F is maximum
-
The water will be held inside the rotor with
the solids that are removed from the oil.
-
Some water will be removed as steam the
higher you get the temperature.
-
A small amount of water may be free water
in the rotor. If water is a real concern you must catch or
divert the last 30 seconds of oil discharged from the
centrifuge. This can be done with a valve or simply placing
a bucket under the discharge at shut down. If you see no
water in the bucket the water is trapped in the solids or is
not an issue.
The OC-50 produces approximately 25% more
centrifugal force than the OC-200.
-
So the issues is how much time do you want to
run the centrifuge unattended to clean the oil and what is
the volume of the oil you have to clean.
-
Multiple OC-50s are more efficient that one
OC-200 based on centrifugal force.
-
Based on dollars to spend you can buy three
OC-50s for the same dollars.
-
You will clean 5.4 gallons per minute and
with 25% more force that one OC-200 cleaning 5 gallons per
minute.
-
You will have to clean or exchange rotors on
the OC-50 ever one to three hours.
-
The OC-200 can go six to eight hours with
out cleaning in most cases.
Motor consideration:
-
The OC-50 requires a gear pump and motor that
will produce at least 2 gallons per minute at 100 PSI.
-
Dieselcraft offer this pump for $549
-
The OC-200 requires a pump and motor that
produces 5 gallons per minute at 100 PSI.
-
Dieselcraft offer a pump for this
application that produces 8 gallons per minute for $1125.
-
You can take this pump and run the one
OC-200 or up to 4 each OC-50 centrifuges
