auto-eject problem
rgrosz78
I recently had a problem where my Hottop B-2K built-in thermocouple hits the 428F limit and ejects the beans prematurely. First time this happened was three weeks ago. It also happened on my first two roasts today, so I stopped roasting!

The beans were 20-40 seconds short of where I wanted to end the roast. Everything about the roasts appears normal, except that they did seem about 30 seconds slower than usual.

I hope someone may have a suggestion for how to resolve the problem. I blow the "leftover" chaff out of my Hottop before I do my weekly roasts, and I empty the chaff tray after every roast.

I reviewed the maintenance notes at the Hottop USA web site for "The beans are being ejected too early":
http://hottopusa....ouble.html

Here are my notes in response to the items listed ... I swap and clean the main rear filter every ten roasts. I did check that the fan is working properly, and I just cleaned it last week. My standard load is 195g, but the espresso roast shown above was 225g.

You can bypass the safety temp sensor. Not a good idea but I did it :)

hottop is not a good choice for espresso roasting unless you remove the safety functions and then it can catch on fire if you are not VERY careful.

Many thousands of people (including myself) have been roasting on Hottops for well over a decade, with the later models being even more capable than the earlier ones. Our roasters are also used on many farms and small roasteries as sample and cupping roasters. One was used to create the first, all-Kona espresso blend in Hawaii.

Life's too short to drink bad coffee.

I will add, Espresso is a drink, not a roast.

If anyone has use for a 1 RPM gear motor designed for a pellet stove pm me. Lowes has a "$120" special order buried on the clearance rack for $30ish.
