Wish List / Re: Go beyond 30 min “Roast”

No - sorry, the longest roast time is 30 minutes.

Wish List / Go beyond 30 min “Roast”
« Last post by KasperV79 on June 16, 2019, 08:31:19 PM »
Today I was playing with my roaster to know how match increased gas impacts the environment temperature. After 30 min testing I realised that the analyser had stopped??

Is that an option to let it go beyond that 30 min barrier.?

Sorry to break your hope...but, it won't be. The first model will have 10 channels of data - reading much more than just temperatures. It is geared at specialty roasters and comprehensive home setups.

Down the road, I do plan on designing a light model - but at this point don't have any kind of time frame.

Thanks, ThermaQ Blue is really pricey, I guess I'll have to wait until you have your hardware available.... Hopefully more affordable than the Q. ;)

Hi Kasper

See attached screenshot.

If you enable the HUD in the Analyzer, you'll see running tallies of the following

1: Drying Stage. This is defined by the presence of an Event, with its type set to "Drying End"
2: Ramp Stage. This is defined as the time from the Drying End Event to the First Crack (beginning of development)
3: Pyrolysis: This is defined by the presence of an Event, with its type set to "Pyrolysis"
4: Development: This is defined as the start of first crack to the end of the roast.

In this HUD, Roastmaster displays real-time tallies of each of these as
1. Duration in minutes and seconds
2. Percentage of time of the whole roast.

So, Roastmaster's Percentage of Development SHOULD correlate to the information on the link you sent, i.e. Rao's Development Time Ratio. Just keep in mind this a percentage, not a true ratio - that's a different thing altogether.

If you're interested in learning how to use events, there's some good information in this screencast.

Yes - it is no small undertaking. Fun...but involved.

I don't plan on supporting any more thermistor style probes like the one in the link you sent. They are fine for kitchen use, but the internal windings tend to fail very quickly in a coffee roasting environment - and they usually don't even cover the required range for most roasters.

The only Bluetooth option at the moment is the ThermaQ Blue, until later this year when I plan to have Roastmaster branded hardware ready for purchase.

Hi guys.
Is it already possible else a wish, to have development timer starting from 1st crack.

Thanks for the reply... Seems it is not that simple to do it I am a hands on but no quite there to code. I wonder if any bluetooth thermometer like this one https://www.ebay.com/itm/Upgrade-Wireless-Thermometer-Bluetooth-Meat-Remote-Control-Digital-Cooking-For/264346152805 could work. :-(
