Coretto cover project

[sidewayss]

Re: Coretto cover project

Ta Mal.

Unfortunately the side effect of all that is a feeling of upgraditis. The breadmaker looks "uncool" with the "cool" cover. Now im trying to cure my itch of painting the customising/painting the coretto.

I dont have an eye for colour matching, so i dont know whether to paint it a different color or use the rest of the tube of the same color.
Instead of using a brush, suppose i could use a sponge and texture the paint. Arrgh! I need a coffee.

Re: Coretto cover project

Yellow is also a good colour for low light conditions
Gary I think stripes would look good on the BM body

Re: Coretto cover project

so gary, have have you noticed the difference in flavor profiles with the new top?

Ive been playing around with it also, although mine is much less fancy, i just use a brickies trowel with a 3/4 circle jigsawed off opposite corners :P

im certainly noticing it a lot more in the cup, although some beans i am preffering much more with an open top as opposed to closed (ie Sumatran)

Re: Coretto cover project

Gary, you could start a path of upgraditis to paint the cover and corretto. A Peerless compressor, hoses, fittings, Devilbiss spray gun, lights, 2 pak clear over base, extra filters, cutters, primer...

Theres about $1200.00 worth to start you off...

Pity you are so far away, Ive sprayed stranger things than a coffee roaster.

Re: Coretto cover project

Okay, i think ill have to slow down now or my other half will disapprove big time.

Going to Red Dot shop to get some doggy stickers and stick em on the coretto. She loves dogs.

Rukudo, i found the result combines the characteristic attributes of the "open" coretto, meaning clean flavours and the FZ-RR700 Baby Roaster, meaning body and oomph in taste profile. I do enjoy it.

I have mentioned it before and again, to be honest, the differences are subtle, but noticeable.

A milimetre or two was required towards the coarse side for the "closed" system due to oils being retained, and not as blown away by the "open" system.

Greybeard, ive upgraded to the Compak K3 and Silvia, so the spray paint full bore option is out im afraid. ;D

Would be fun though, if i did a course in spray painting and qualified, i could offer my services to pimp roasters, grinders, coffee machines, knock boxes etc.

Re: Coretto cover project

Gary, youve gone mental dude.

nice lid. hah. Im still using a kitchen floor tile on mine, I slide it on / off as I roast to keep my profile perfect, because the temp adj on the HG is pretty useless. Works a treat. I suppose a nice bearing/sliding lid would be better, but not sure its worth it, only roasting once a week

Re: Coretto cover project

Gday James,

I cant recall if youre using a heatgun stand in your set-up? In my case the heatgun nozzle is inserted in one hole and is kept upright on its own. Then i adjust the fan and heat settings on the gun.

Got some paint left in the tube. If you want it, you can have it to paint your tile. ;D

Good to know youre getting the results you want.

Re: Coretto cover project

I just start a Corretto project by learning from this forum.
Different shape but similar idea about with a lid/cover on it.


So far not very good at controlling the heat gun/temp.
I believe I need a wire probe thermometer instead of the stick one.
Then it can measure the bean temperature instead of air temp.

Thanks for Corretto and people show their device.

Re: Coretto cover project

Gday Colin,

It is more tricky controlling heatgun temperatures and adapting to the cover and the effect a cover has on the roast.

Id suggest sticking to the stick/steel probe one if youre measuring bean temp and use the wire one for air temp, otherwise the wires will get smashed up by the beans unless you use something that will protect the wire.

Theres info regarding installing the probe through the breadmaker and into the bread pan.

Currently taking photos of my latest cover using fibroboard a la Mals.

Will post the pics later today or tommorow and hopefully it may assist others and yourself who are doing a similar project.

Re: Coretto cover project

Thanks Gary,
I drill a hole from outside to inside, and attach the thermometer.
I roast my second batch (PNG), I still can not hear the 1st crank and 2nd crank.
After reading other post around, I may get a Data logger to monitor the roast profile.

Re: Coretto cover project

Here is my second project, coretto cover Mk 2.

The first one was the KK inspired kindergarten style clay moulded cover, shaped and painted. Effective roasting improvement for $20 outlay.

This second example is Mals inspired fibre cement cover, measured and cut.
Works just as well as the clay cover IMO.

Simple, and effective costing only $10 for a large from a hardware shop, so if you botch it up, you have the substantial remnant to start again.

The only tools you need is a measuring device such as a tape measure, pencil, hole saw and drill, a hacksaw or a regular saw.

Bits n pieces include a cork as a handle. A screw to hold the cork in place.

The cork i chose was a Louis Bouillot Cremant champagne cork.
Some examples of corks i had lying around include Penfolds Grange, Henschke Hill of Grace, Jim Barry and Inniskilin to name a few but a champagne cork offers better grip for the times i might find myself scrambling to remove the beans to cool.

These two covers i have used so far together with the fire blanket insulated breadpan have resulted in improved quality in the cup, due to decreased heat requirement.
The beans themselves look nicer, more even, very little if any divots and tipping.

DMM logging with the accompanying software is a recommended and useful tool for anyone getting to grips with it, as going from an open coretto to the closed one requires re-adjustment to the heat and fan settings on the heat gun.

Its a project thats easily achievable for anyone with simple tools. If you dont have a hole saw and drill, you can use Mals example and just cut out a couple of corners, one for the heat gun, and one for the exhaust.

Give it a go. 8-)

;D
Now thats snobby!

Champagne cork makes a lot of sense, a great handle.

Heres how I protected mine.

Basically though I drilled 2 holes in the breadpan.
One to feed the wire though and one to take a screw to hold the wire in place with a washer.

If you feed the wire in flat against the side of the pan (not touching) pointing in the direction of the bean flow, it doesnt get damaged.

The screw poking into the pan can also offer some protection to the bead as it will be hit by beans before they reach the bead.

Could have used Veuve Cliquot, Krug, Bollinger, Perrier-Jouet or Dom Ruinart corks but they have already been consigned to corkboard deco and acoustic treatment for the listening room.

Fibro cement as well as clay covers can be handled without handles if anyone wants to keep it bare bones simple.
They feel warm rather than hot to the touch, so they can be grabbed by the edges and removed.
But having a handle means it is easier and faster to grab especially if you are wearing mittens ready to remove the bread pan to dump the beans.

Based on your great solution TG, im keen to apply that technique to connect another probe (wire) in order to measure ambient temperature in the breadpan via a secondary DMM logger as an accompaniment to the current stick probe which measures bean temp.

Re: Coretto cover project

Lots of interesting development here! That fibreboard sounds like the go - I might line the underside of my steel lid…
Ive certainly found with a cover and now having insulated the pan Im getting more body in the roast - but Im also needing to pull the roasts a bit earlier as I think the heat input gets in deeper sooner - some of the roasts seem lighter (CS7-8 ish) than Im used to, but richer in flavour. Talking slight degrees of difference, but certainly noticable.

Forgive my ignorance - is the concept of monitoring the ambient at the same time as the bean mass just to get a reading of the ambient starting temp, or to record the ongoing ambient rise in the actual pan? How would knowing this info help with heat input decisions?
