![]() ![]() A system like ColorTrack’s has the potential to not only get around the influence of air temperature, but also to allow the industry to finally have a universal standard for discussing bean color or temperature during roasting. air heavily influence data from the probe. The air temperature surrounding a bean probe and the proportion of the probe’s surface in contact with beans vs. For example, ColorTrack offers a promising laser “ RealTime” color-reading system that seems promising. The best solution would probably involve remote sensing of bean color or surface temperature using some kind of laser or infrared technology. If every roaster used the same bean probe, it would make roast data across different machines more similar, but still not identical. Is there a way around these bean-data problems? Perhaps. For example, a recommendation to aim for a certain DTR, roast time, or general roast-curve shape (i.e., avoid a crash or a flick) is useful to apply to almost any machine and probe, assuming one understands the context in which the recommendation is made. This problem of different probes presenting such different numbers is why I focused on ratios and rules of thumb in CRC, and avoided too many prescriptive numbers. (Please ignore the blue curves.) Note how the turn occurred at 2:00 and 115℃ (239℉), and the ROR did not peak until after 4:00. The top graph represents the bean curve and the bottom shows the ROR curve. Here’s an example of a curve tracked by a 5-mm probe (my apologies for the different formats and switching between ℉ and ℃): I had mentioned the effect of bean-probe diameter on roast curves to Tim and he immediately installed a 1.5-mm next to his 3.0-mm probe, hooked them both up to Cropster, and sent me this curve. Leaving aside the fact that the turn doesn’t really exist (see pages 20 & 30 of The Coffee Roaster’s Companion), not only do different machines, batch sizes, charge temperatures, etc., influence the time and temperature of the turn, the speed and diameter of the bean probe does, too.īelow is a graph of an experiment done by my client Tim Burstow of Sleepless City Roasters in Toowoomba, Australia (I love Australian town names!). Is that a significant finding worth applying to other machines? As it turns out, not at all. For example, let’s say on your machine that the turn occurs around 1:30 and 85℃ (185℉) on all good batches. When a roaster has used only one machine, it’s difficult for him or her to know when it’s appropriate to generalize findings. Using so many machines has yielded some surprising benefits, among them learning how easy it is to be fooled by bean-probe data.

Update to last post available in comments.The two biggest perks of my job as a consultant have been meeting an extraordinary number of lovely coffee people and getting to use an incredible number of roasting machines. ![]() They damaged decorations, small improvements, and paint. Caused damage/destruction to a former employer's place of business (no law involvement, of course). I'm aware getting mail/actually residing in our house for 1.5 years gives them rights, which I don't want to violate. We were helping them get on their feet, that type of situation. In-house, non-separate single room with shared space in kitchen/etc. Tenant of a year and a half does not pay rent. ![]() The landlord is not required to give the tenant notice before filing an eviction suit. If a tenant fails to pay rent, the landlord may immediately take legal action to have the tenant evicted. Because they don't pay rent, we tell them to leave, then go to court and file for eviction immediately? Found here but not sure it applies to us without a lease: ![]()
