the &^%&^%*& thing will then try and float on you as it does it’s job. ideally you’ll want to make sure it can’t. or at least limit it’s range of motion.
you’ll want about 1kw for each gal of solvent you want back per hr. that’s a slight overkill, but it doesn’t hurt to have extra heat if you might want to double the boiler size before upgrading the heat source. You’re also heating up a big bolus of water, so you want that little extra there too.
a single 5500W water heater element should make your 8gal still more useful. there are off the shelf controllers that can handle 2 of those.
The 100gal still I’m working on getting permitted has ports for 5 of those 5500W elements, but in this application the heat source should be in the next room imo.
How did you come up with the 1kW per gallon per hour figure? What temp are you introducing your ethanol mix at and what is your target temp for boiling it off? The math I have on latent heat of vaporization and real world experience suggests thats significant overkill for 1 gal/hr recovery
but I did neglect to give the more accurate 0.75kWhrs, because I was taking into account that big bolus of water.
I was also assuming they would graduate to a 15gal keg in the same 50gal boiler without upgrading the heater. I apologise for not showing my work. I did state the reasons for running with a known high estimate.
we design and sell unit that can distill this quantity of ethanol. we are currently finishing a build that would process about 80-100 liters of ethanol per hour. we are also adding a purification system for the ethanol as well so its a better quality of ethanol for re-use in the clients set up
most people seem to be highly interested in our agitated systems. it depends upon what volume you are looking to remove from your product and to what levels you are trying to achieve?
This quote really focuses in on the biggest problem for ethanol extraction, which is purging solvent. If you use less solvent, your equipment can be scaled down too, and still push out a lot of crude.
No, we make our own systems in our 25,000 square foot facility located near San Diego,California. we also offer integrated distillation equipment both large and small scale and are specialist in fractional distillation and purification of unique products including herbal extracts. We do our own internal designs and also offer technical consulting. we are NOT a Chinese company and we know some people prefer China since it is lower cost but we are very economical and can compete with China
@DrJosh are the pictures above supposed to be your solution for recovering 80-100liters of Ethanol an hr? Can you explain where the required heating or cooling is coming from?
Or where the 100liters of Ethanol is coming from or leaving to?
If they are NOT supposed to represent the system mentioned below, why exactly were they posted?
@QGA asked for pictures in response to the above. So the logical assumption is those pictures are supposed to be your recovery solution.
I don’t see how either unit shown can recover 100l an hr for more than 2min as pictured, nor do I see anything approaching the required heating or cooling.
Can you please clarify the relationship between the pictures, and the unit you’re suggesting the OP purchase from you to recover 80-100liters per hr.
