Hi CSrs,
I was fortunate that a friend acquired for me a bread maker (Sunbeam Cool Touch Bakehouse) with a larger bread pan (than my Mk1).
I decided to set it up as my new No.1 coffee roaster, according to my current knowledge, practice and preferences,
Removed the electronic control circuitry and after a good clean, judged it to be in good condition and suited for intended use.
Wired the heating element and motor directly to standard leads with 3 pin plugs.
Drilled a few holes in the lid (with a mates help) and constructed an internal cover from aluminium sheet to assist with management of heat flow and venting.
Dived in at the deep end with a too large 1000 green grams roast, first crack at 13½minutes and overlooked 2nd crack and finally pulled at 19 minutes, a bit too late.
Heat supplied by my old Mk1 heat gun (a SH 1600W Craftsman) and original Sunbeam element.
Roast progress monitoring assisted by my Ebay Turkey thermometer @ $10
(Andy’s TC and software still on my Xmas list).
Chaff dispersal by the occasional blast from the blow side of my old Electrolux vacuum cleaner mod 725
Finished? Well no, but further tuning has now officially begun.
Exhaust port and chimney Improvements to the structure and detail.
Insulate lid, space between: metal liner of lid and the exterior plastic (PP) skin.
Insulate oven chamber and upgrade cooling to stirrer motor.
Kind Regards
Lindsay
Image1 illustrates what it would look like on the way to first crack with beans on board.
Image2 The detail inside the lid: -heat gun throat, turkey thermometer/TC, chimney and observation window.
Image3 The elegance of the internal cover, intended to limit hot air loss from element and assist with moving heat into the bean mass etc.
Image4 The naked bread pan/roast chamber.
Image5 The hand crafted elegance which is the internal cover, constructed from about 0.6mm aluminium sheet and cut with sturdy scissors.
