Roasting Guatemala with an eye on energy use

-

First tweaked the sliders in Artisan to heat up the machine with a lower airflow, keeping more heat inside the machine. This cost 0.087 kWh

Warmup started at 19:31 for 15 minutes, using 0.686 kWh

CHARGE happened at 19:47. Shortly after, energy use declines as ever less heat is needed.

FC at 19:58

DROP at 20:01 after using 1.264 kWh

Cooling of the roasted beans took 2 minutes

Switched OFF the roaster at 20:05 having used a total of 1.274 kWh for the roast of 1700g green beans





Batch 8:

Start warmup 16:04

CHARGE 16:19 at 0.732 kWh

DROP 16:34 1.272 kWh

Machine OFF 16:35 1.277 kWh


B9 on 27 dec 2021:

ON 19:15

CHARGE 19:29 at 0.667 kWh

DROP 19:44 at 1.24 kWh

OFF 19:45 at 1.246 kWh


batch 10, 1500g green:



batch 11, 1500g:

Warmup 0,63 kWh

FC at 1,132 kWh

OFF at 1,212 kWh



Batch 12, less energy (1500g):

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

-
Afbeelding
Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid...

KiwiSDR2 [radio]

  Despite selling one and giving away two of the five monster vintage 'boat anchor' receivers that I had, I still enjoy listening to shartwave radio. The modern iCOM R8600 that I also have has a wider range plus some decoding options but it's not easy to figure out what encoding is used on which frequencies. The SDR-Control app from Marcus Roskosch at https://ham-radio-apps.com/ makes this much easier and also allows some remote control of the receiver so you can place it and an antenna at the top floor of your house while listening downstairs. I also got the SDRplay RSP1B box: This offers a great listening experience at a very low price compared to the iCOM hardware. I had one before and bought one again after a (somewhat limited) Mac version of the software became available. This device needs a computer to be connected to the receiver. For some time now a nifty little device has appeared which not only works standalone, it even allows you or anyone else to utilize the ...

Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics.  On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the...
