Hi all
Current Coffee Roaster Project
I have the plans and parts of my new roaster
(I would like to advise that some of the design ideas for this roaster were borrowed and others are my own)
Just putting it out for comment prior to final assembly
***NOTE: My wife had a say in this design and what she wanted was
“Not to see the roaster when not in use”
It is made to fit under our BBQ, in one of those S/Steel doors***
Please read the description carefully
If anyone has any tweaks or recommendations “speak now or forever hold the peace”
++Also NOTE this design can be used just as easily with a heat gun as the heat source
OK just a general description starting from top to bottom (see picture/drawing)
Turbo Oven (Tiffany Model) sits upon a deep straight sided stock pot
Edge of pot lip has 3 or 4 pieces of tubing that the glass part of the Turbo Oven sits on softly; this set up also lets some heat and pressure out from the gaps.
Inside the pot I have a steamer insert, smaller in size form the stock pot, the steamer insert sits on spacers or legs.
Steamer insert is made to always fit to self centre and correct height for agitator connection point.
This self centering feature allows the Thermocouple housing which is a permanent fixture to be at the correct height/depth of the bean mass. Thermocouple housing is fitted from under pot but the probe itself can be removed or inserted as required.
Housing is a small (tiny) diameter copper pipe pushed into a brass fitting
The position and size of the steamer insert allows heat to pass through the bean mass and deflect back, heat is also directed around the insert in a turbo motion creating an evenly distributed heat source.
The steamer insert holes act as a chaff separator and sifter
As the agitator turns the beans the chaff falls down through the holes and collects at the bottom of the pot away from the roasting beans
Agitator is connected to a car window motor under a board on small legs allowing space for motor
By placing the motor under the board it is protected from heat
The stock pot it self is held above the board by two metal strips and the pot can be made to swivel if necessary to allow for the chaff to be disposed by tipping
The blue circle you see may be needed if I need more ventilation so a hole saw will cut out the hole the removed piece will be used as an adjusting gate.
So what do you think over to you?
