Compare the bizzy system with the delta system
They both have the same heating and cooling but the delta does 60 gph vs bizzy 45 gph
Only difference is 1 plate heat exchanger used to cool the evaporated solvent with the incoming crude

Unfortunately most of the delta auxiliary units were undersized for their stated throughput.

The 2 I ran hit 60 gph using 48 kw heating and 10 or 12 tons cooling if I remember correctly
35kW of cooling will not support 227LPH. We are running into issues with most delta ffe45ās maxing out around 25gph while at that 7c cooling water. Sure you can bump up the chiller temp and raise the pressure inside the evaporator but that comes at the cost of oil quality.
We own all the delta ip and designs now, the good thing about the delta FFE is there is a ton of surface area on the machine.

You mean
You mentioned 10 tons of chilling. Which is 35.1kW
If you were getting 60gph, thatās awesome for 10tons.

Coming from your own engineers on your system (which is less efficent because its missing the plate) that doesnt seem right considering 25 gph is like 97 liters
It might have been 12, i dont remember exactly. I know the heating and cooling should be pretty close to the same power
I had nothing to do with Precision or bzb, I think you have me confused for somebody else.

I know but a bzb enginner who did the testing on the original units said
So the fact youre claiming a delta with the same cooling power can only do 25 gph seems weird considering the delta has the plate to preheat the incoming crude / cool the evaporated solvent
Iām not saying that, customers are. They originally only sold the 45gph model with a 5ton chiller..

Iāve been running a bizzy bee FFE for the past 2 years.
Iām currently only seeing 25-30 gph with 10 tons of cooling at 5c and 48kw of heat at 180f. My GPM on my heater is a little slower than I would like which could be a main factor in my overall recovery speed. If I had a better heater that could push heat fluid faster I may see an increase of recovery.
The initial specs of bzb ffes:
30gph with 36kw of heat and 10 tons cooling
55 gph with 48 kw of heat and 15 tons of cooling
The recommended heater temps set to 180-200f
The deltas 45/60 FFE are only making those claims as potential throughout and Who knows if thatās with or without cannabinoids in that tincture or if thatās just virgin ethanol. I personally donāt know anyone in the field whoās actually hitting anywhere near close to 45 and 60 gph on a delta FFE. The cross flow exchange on the pre heated plate exchanger is nice but thereās some potential variances there with vapor temperature and inlet temperature of solution which can give a variety of results in overall efficiency. I see a risk of sugars potentially getting clogged in the plate as a pre heater if there are sugars present in your crude.
Iāve personally never ran a delta FFE so I can only speak so much about it.
This is a custom type of evaporator, Iām looking to get ~35gph with Heptane, using 37kw heating and using 15.1 tons of cooling power. heating flow rate of 21gpm.

You will be able to achieve that no problem given the setup is right. Heptanes heat of vaporization is quite a bit lower than ethanol, youāre sized right!
