Hi guys
I am looking for a bit of input on an issue i have had the last couple of days. There is an oil fryer in the plant which has a couple of belts in it. The first belt is a non stick teflon short belt on the infeed which is driven by a stainless steel enclosed motor. The motor was running fine until the production changed onto a different product (a salt and chilli product) and after an hour or so it stopped driving the conveyor. The motor is run on an inverter and is switched on and off through a HMI screen and all of those were ok, no faults and no issues with the mechanics of the shafts, conveyor etc. The conveyor is submersed in the oil at a temperatur of 180c. Nothing has changed on the whole system and the motor and inverter are properly rated and everything else in the fryer is as it should be. I swapped out the motor out with a spare at the end of the day (same stainless steel motor) and ran it and it was all ok. Voltages, current, and loads all ok when measured with meter. The spare motor ran for 2 days after i changed it and there was no problems. But the same thing happened again tonight after and hour when they went back on to the salt and chilli recipe. I wasnt there to witness what happened but they told me over the phone the motor has stopped the same way it did and when they opened the panel there were no trips or the inverter wasnt showing any errors. I wont be able to look at this until the morning but i am wondering is there something in this recipe causing this to happen. I am at a bit of a loss on this . FYI the stuff going through the fryer is chicken breast covered in this salt and chilli flavour.
This may sound silly but i am wondering is there salt and chilli conducting in the oil and heating up more, or would it be doing something to the conveyor in the oil which is causing the motor to overheat? Any input or experience.
