FrankenRoast - Fresh Roast SR700

January 11th, 2019, 12:04 am

Hi all,

I am working on my SR700 as I wait for my R1 to arrive. I have made a few mods but wanted feedback to see if anyone could think of an easier way to collect the chaff while still loading the beans in an easy fashion?

Current setup:

Well done, can you expand on what you've added or modded? Like the idea of having a separate chaff collector.

Hey Rob,

I hope all is well. I have done a few things:
1. Added Phidget setup to monitor BT and ET
2. Had a larger glass chamber made so I can roast up to 300g
3. Modified the heating and fan elements to increase heat and air flow
4. Custom scripts to control roaster via Artisan
5. Added the cyclone and the funnel system with a few other parts I am waiting on.

Here is a picture before my last modification:

Cool, 300g is a nice amount for the average home user for consistent fresh coffee. Bullet R1 can hold 1kg but can also roast 500g comfortably. A lot of useful mods. Have you estimated the costs of your additions. I understand that it's not always about cost when learning and developing.

I am excited to up the load with the R1 so I can share my roast as well with others. I have no idea on the cost I would say maybe another $300 or so... I am doing it to help learn more about roasting and each stage. If anyone is interested in doing this, I'd be happy to send over the parts that worked vs. the ones that I trashed, and you can probably do it for half the price.

FrankenRoast vr.2 is alive! This version is a bit more streamlined and added bean loading funnel to allow for pre-heated charges:
