removed processor stuck to cooler by first trying it with dental floss advised here:

But Floss will break quickly.
Then used a very thin 0.3mm thick and strong string holding with gloves. put the cooler to the side, processor towards you sitting on a nonslippery surface.
start by moving string left-right-left at one of the top-corners of processor. It will immediately be seperated. no heat and other solutions needed.
dont know anymore for what i purchased it on ebay from china.
