TJ-067 1kg electric drum roaster.

[Kevo]

Still "under construction" mate.
My electrician is dropping in tomorrow to get the details for him to source a replacement relay.

Yes, John's the supplier whom I have chased up spares, but a lot of water has run under the bridge since and on Mal's advice here, I'm using my local sparky to chase one up.

It seems now with the age of the TJ that John's "factory" no longer use some components fitted to this roaster and now use a different supplier components, hence the delay?

Apparently John is in China at the moment and has apologised for his lack of communication due to poor internet where he is??

So it's a waiting game ATM, coping with the frustrations of not being able to roast and surviving on browns from a local roaster here in the Hunter area.

I posted this to find out if anyone else that has bought one of these has had their wiring (earth) checked, because I am now reading that this could be, or is common for these roasters from China.

I know way back beanflying bought the first oz landed one from John and posted a well-detailed review that has since been removed from the forum, but there must be others (perhaps not on or less frequenting this forum)!

My JYR (CCR) is well out of any implied warranty, so this is just another 'buyer beware' message I suppose.

thanks.

Actually after carefully considering the Aillio Bullet i have ordered a 1kg gas version from him and its due very soon.

Re your electric one ( these are just thoughts btw i am an Elec Eng not an electrician):
- is the supply Circuit breaker an earth leakage type? ( because if it is the trip could be an earth path from the machine to the ground ( ie floor) - that would be enough to trip it and might indicate the body of the machine could be live
- this may also explain why the earth was removed, that would prevent it tripping unless there is an alternative path to earth rather than the lead.
- thermal elements can have an imperfect isolation to the outer casing and leak more than the 30mA. You may be able to upgade the leakage circuit breaker to 100mA type for 15A circuits.
- thermal elements can break down internally but still work- i.e. they are on the way out. As they break down they can draw excessive current/power
- maybe one of the elements is causing a leakage current. Get the sparky to do an insulation test. A proper test is done at 500V and is a special tester ( not a regular multimeter on Ohms)
- there is a mob in Melbourne Hotco who can make custom elements to suit, I have dealt with them and they are OK.

Thanks for your thoughts mate.
I will run them by the electrician tomorrow (if he remembers to turn up) ;-)

Okay, an update on the roaster situation.

Electrician purchased a new relay off the shelf from the local electrical supplier 4 blocks away!

Fitted it this morning, checked all around and turned the roaster on. Everything ran okay with no tripping except the drum wasn't rolling as we hadn't yet plugged in the replacement speed controller.

Turned on the elements and watched temp rise and then the electrician noticed the exhaust fan under the drum wasn't working. Power going to it but not functioning.

Now as far as I know this may have never worked or stopped working a considerable time ago and would explain the heat affected speed controller and a few other signs of excessive heat.

With my minimal use of one or two roasts per month, it has deteriorated the "electrics" to a stage of tripping the unit more often than the once in a blue moon I was previously getting.

The sparky agreed that you wouldn't know if it was working because of other operating noise.

Now sourcing a new fan. (On the way).

Hence why I removed the stock fan on mine and added two 150mm fans. It now keeps the electrical compartment at a low operating temperature. Early days of having my roaster I blew a SSR and couldn't figure out why until I realized that it was just too hot and overheating components.

After I did that modification I was able to do 10+ back to back roasts no problem.
