Here is the problem I see with the vito system – what about the stuff at the very bottom of the tank?
I’ve used the big roll-around oil filters, and while they’re cumbersome and annoying to clean, ALL of the oil leaves the tank, you rinse down the tank with filtered oil (to get EVERYTHING out), and then refill with the filtered oil. You do lose some oil in the process because of having to vacuum it all out of the filter machine and pump it back in. In our chicken fryers (fast food joint that did a fair amount of fried chicken), there was a big “cup” at the bottom that was almost full of drippings and droppings, probably a couple of quarts on a daily basis. While the Vito system isn’t aimed at true chicken fryers, these types of issues cause me concern.
I have even deeper concerns about the clabbergirl stuff. While it sounds really neat, until you can get the particulate matter out of the oil, you’re still breaking down your oil by having the contaminants in there.
However, from an employee (worker) perspective, they both look like giant time-savers and mess-savers.
