gonna have to drag the roaster out here is a day or two sure hope it warms up some, been kinda cool here in OKC with it being only 28 degrees this morning. Makes a guy wish he'd built himself a toy shed you know what I mean. Well its getting pretty close to time to roast some beans for the swap, I sure hope my roaster don't let me down in this cold weather. David I pour Iron and roast Coffee Beans

When it's super cold I start the roast in the (one car basement) garage with the door closed until I get close to 300F bean temp... then open the door. If the temp is too much of a problem I'll shoot a heatgun at the inlet. CHAD Roaster: CoffeeAir II 2# DIY air roaster

dang Chad it must be nice to have a nice warm garage to park in, I guess I could put in an overhead door on the slab then I could pretend like I got a garage, open the door and pull up onto the slab, but then I would have to go buy a heat gun. Why you have to add the gun heat, I got the same coils as you and I can get hot enough to roast in cold weather. Edited by dja on 11/28/2011 7:09 PM I pour Iron and roast Coffee Beans

Yeah, it will roast, but when it's cold it won't let me go as fast as I want during some segments of the roast so I throw in some extra heat (this is also the advantage of Kirby's all metal construction with heatslinger for keeping the motor cool). Hey... I thought you were complaining about roasting in cold weather? So it must be YOU that's cold and not the roaster!  Having a little fun David!CHAD Roaster: CoffeeAir II 2# DIY air roaster

well I knew it would happen just never knew when. Roasted up some of the rawanda that I had received from Chad in the last buy, well when I pulled the beans I removed the thermal couple from the bean hopper and turned off the blower and guess what, I left the heating elements on and had a total melt down like a reactor on steroids. So now I get to find a relay that will handle the load of the coils and wire it in so that when the fan is off the coils are dead. I pour Iron and roast Coffee Beans

...and that would be a rather large contactor..Instead of a large relay, you might be able to do what I did: Power the temp controller, that supplies the DC voltage to the SSR from the fan circuit. . .

Ok I finally was able to take the time and fix my roaster after melting the heating coils out of it, on my first roast of the Rawanda that I got from Chad on the last group buy. anyway heres a picture of what I pulled out of the roaster  Not very pretty, the other side is worse, but only have the one photo. but thankfully the roaster lives to roast again and hopefully I'll remember to turn the coils off, price of coils has went up some since I bought the last two when building the monster(roaster) Edited by dja on 03/14/2012 10:04 AM I pour Iron and roast Coffee Beans

A relay to handle the power to the heaters? Have you considered an electric toaster? I was cleaning mine a few months ago and i discovered all kinds of neat little safety interlocks built into it. They all have to be engaged to keep the heater on. There is a small relay,2 chips, 5 transistors if i remember correctly, the relay is actuated when you depress the lever and it energizes a solenoid whlch holds the toast down. This solenoid also holds closed the 2 contacts which deliver power to the heater.
Bad coffee prevails when good coffee roasters stand by and do nothing.

David! I had to idiot-proof mine in order to accommodate my hap-hazard-ness. I can't turn the heat on unless the blower is on. Should be a pretty easy fix no matter how yours is wired. CHAD Roaster: CoffeeAir II 2# DIY air roaster

yea I know, my stupidity is what did it, that and old age guess I could take one of the old pressure switches that I have off an asphalt plant and plumb it in so that they coils won't work unless the switch is made, but then things are so big. guess I'll have to find an easier way

..as an extra precaution I don't plug it in unless I'm roasting, but the SSR receives no switch power unless the blow circuit is on. Of course a pressure switch is the very best protection and all commercial grain dryer application have them.
