Monthly Review – January

I am reasonably please with progress on the roaster project for the month of January. As is always the case with “the first creation” part of the process, I have very little to show for it. No roaster, no experiments, no coffee… nothing tangible except for sketches, articles, and notes.

What I do have is a much better understanding of the scope of the project. I’ve learned plenty about areas that I don’t know and will need to know or subcontract. I’ve met several people and talked through ideas, which for me is always a way of refining ideas (I’m generally a verbal processing thinker). Writing the blog has helped in a similar way and I’ve enjoyed the feedback. The sort of roaster that seems best to me is starting to vaguely take shape.

Here is my laundry list of things I need to work on over the next couple of months.

1. Learn more about burners (power, ambient and infrared)

2. Learn more about high temperature blowers

3. Learn more about temperature sensors (contact and non-contact)

4. Examine sources for motors and variable speed drives

5. Learn more about Arduino, PID, and other possible control systems

6. Examine sources for linear actuators and stepper motors

7. Learn more about colorimetry, possibly visit Agtron

8. Examine sources for high temp bearings

9. Visit local machine shops and welding shops

10. Find local foundries and multi-axis water jetting shops

11. Build some sample roasters

12. Start interacting with green coffee brokers

13. Determine the necessity of getting UL approval and process

14. Study Victorian era detailing and Steampunk aesthetic

    I really like the direction of this project. I think that it will be very usefull to meet periodically
    with Joe and collaborators. There are some of us that are already familiar with Agtron or Agtron
    like spectrophotometers or colorimeters as well as temperature controllers, thermal couplings, I/R and even roasting software. I also believe that to discuss all different methods or roasting. As well as roasting
    techniques here in the valley as well as sharing all existing working roasting machines
    here in our State (I personally have 4 different commercial roasters that will like to share and I know of other 5 from personal friends and colleagues). I thing it will be very educational to observe as many
    machines of as many different design as we can in order to perfect a new design.
