Gothot's La Coronita centrifugal roaster

-
This morning I chanced upon footage and pictures of a vintage roaster, currently owned by LI-MING machinery (Lin T / Joe Lin) in Taiwan who are restoring the machine for use as a sample roaster.

It's magnificent, looking like a machine out of an eighties sci-fi movie:






One of these machines was built in 1983 and sold by SHP Food Machinery in 2011. These pictures are on their website:

La Coronita by Gothot
Hot air blown in from the top, a cone spreading the flow, pushing beans up along the curved walls, past the curved blades, back to the center.



When Jan van der Weel and I visited PROBAT some time ago, we saw a huge version of their roaster based on the same principle. 

A former employee in our tour group explained to us that at the time, this 'flying saucer' shaped giant enabled the roasting industry to save lots of time and energy roasting as thousands of kg's of coffee beans would be ready in as little as three minutes. A better taste was possible with roast times up to twice as long though and eventually the industry again preferred different designs for their large scale roasting machines.

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

-

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...
