I have a video, can you send me your email?
Did you find a decanter centrifuge for your biomass? We have several options available depending on your liquid solid percentage and flow rates.
Is there a desire on the forum to have access to professional process engineers? I know quite a few and i’m sure some of them would be interested from a purely academic standpoint.

Hi, The decanter centrifuge is great for extraction. The decanter does not squeeze your biomass but instead uses G-Force to remove the solids. After going through the decanter your solvent will have <1 % solids. The solids cake will be very dry.
We have had success removing most of the solvent from the biomass with a decanter. With a full variable speed decanter you can change the speeds to increase or decrease residence time allowing you to fine tune your process and produce a very dry cake.
The ‘contact time’ you mention is typically known as ‘retention time’. It is totally adjustable by simply reducing or increasing the flow through the centrifuge.
For example - if your bowl volume is 5 gallons and your flow-rate is 5 GPM - the retention time is 1 minute. Now, if you were to use the same bowl and reduce your flow-rate to 1 GPM your retention time went up to 5 minutes. In other words, retention time is inversely proportional to flow-rate.
In the real world, you may take a high capacity ( let’s say 60 GPM) centrifuge and process your fluid at 10 GPM. You will get extremely generous retention time which will lead to much better separation. Of course, there needs to be a balance between the rated capacity and actual flow-rate to justify the cost/value of the equipment. But we have had quite a few ‘challenging separation’ situations wherein we have over-sized the centrifuge to increase the retention time and get desired results for the customer.

Looking for a used decanter centrifuge. A small one is fine for what I currently need.
Im looking for a decanting centrifuge that will allow me to process approximately 4,000 lbs a day. Closer to Denver the better, also want to buy the peeler that can dewax at same rate as the decanter can separate. Anyone got one for sale?? Thanks in advance.

Have you looked at discountcentrifuges.com?
They have decanters and peelers in addition to less exotic solutions.
@greenbuggy may still have his decanter
Ended up selling mine to a machinery dealer who wanted it, I know of a new Chinese import vertical basket centrifuge for sale in the Denver area but no decanter style ones at the moment.
