I got this fryer from my dad.He bought it because it was dirt cheap and looked great.At first, even at the 375F setting this frier would not get any hotter than 360F, so I decided to sell it on Ebay, and get another one, since Im starting to do some experiments for a Burger Franchise @Burgerhaus.
I had a burger fest on a weekend so I decided to try frying about 10 KG of fries on a Sunday.
The frier worked great, but sometimes the temperature was not enough when frying 1KG at once on the 2 baskets.
After looking on how the temperature sensors are secured, I decided to try modifying the fryer.
It seems that the sensors are perfectly calibrated for the temperatures on the dial. However, this sensors are attached with a metal plate directly to the heating element, so what the fryer actually reads its an average from the Oil temp and the heating element temp.
Removing the supporting plate and 2 screws that hold the sensors, allows the fryer to correctly read the Oil's Temp.
After doing this, the Presto Profry will get up to 390F as peaking point, and work at an average of 370F on the 375 on the Dial. 365 Peak and 350F average on the 350F ,and so on. The fryer will work perfectly after that. (Look at the pictures with the Thermometer @Customer Images)
I rate the fryer a 4, since this is a little design flaw, and also because it does not have an oil filtering system like other fryers.
Other than that, and after the mod, this is a SUPERB Fryer for only $69.99
I higly recommend using Palm Oil, High Smoke Point Peanut Oil, Soy Oil+Palm Olein. Do not use Canola, Olive, Sunflower or other Higly Monosaturated oils as this have low smoke points and will be health dangerous at any temp higher than 350F.
