"Your Partner in Industrial Innovation!"
Contract Design and Development Services:
Coffee Cognition was founded by Stephan Dednam in 2009 with the goal
to supply the highest grade Arabica roasted coffee tailored to
individual tastes.
Coffee Cognition have partnered with ALFTECH to manufacture a line of
coffee roasting machines. The first all electric Coffee Roasting Machine
is in prototype stage and will be ready soon for full time roasting
duty.
The sample shop roasting machine is designed with the
aim to produce the most consistent and repeatable roast time-after-time.
We have taken great care to design the roaster with a dedicated
precision digital feedback and control computer, assuring that even the
most everyone can make the best roast, consistently.
We have also focused on improving the overall energy efficiency, and
have built in energy (heat) recovery and thermal insulation as an
integral feature of the whole air heating and bean roasting circuitry.
Provisional Specification:
- 1.5 kg (2.5 kg Max.) Batch Roasting;
- 16 A (Max.), 220 v Electrical Supply;
- Integral Roast Control Computer with roast data logging (triggered by opening of Coffee Bean hopper to load the next batch, and then by the opening of the Roaster discharge door). A detailed roasting profile is logged in the Roast Control Computer;
- Optional USB communications with MS Windows based batch profile creation software (included at no extra charge). Easy batch profile selection from the Roaster Control Panel (and accessible from the USB attached computer when connected);
- Integral batch logging for detailed quality/repeatability analysis and accounting (requires USB connected MS Windows based PC);
- Accurate and "closed loop" digital computer controlled and maintained Roaster heat profile. The Roaster accurately maintains the preselected roast temperature, or follows a pre-programmed (and selected) roast profile;
- Easily visible batch countdown timer and "Roast Ready" alarm;
- Integral Cyclone chaff separator, with heat energy recovery for improved thermal efficiency;
- Integral post roasting cooler with dedicated cooling circuitry. Manual or Automatic operation (triggered by opening the Roaster discharge door);
- Shop roasting model offers Foot Mount (stand-alone frame) or Floor Mount (required bolt-in-floor attachment) options;
