Re: Coretto cover project

From my school day memories
We used to enamel or pottery glaze our handy-work I think my mum still has one of my mothers day presents some 40 years later

Its still your best option

Re: Coretto cover project

Right then, we got "Gumby" from Mono, I have thought about "Bread killer", "Salmon Belly", "Home Sweet Home", "1st Grade", "Two Eye Bob", "Special KK" just to name a few.

I wonder if i should turn this into a competition to name the lid. 250gm of my finest roasted browns to anyone who can present the best name.

In the meantime, i intend to paint the handle red to represent the nose, and mould a set of lips and broken teeth to represent the mouth.

Re: Coretto cover project

Thanks KK and Greenman.

Kudos to KK for your suggestion for the clay concept.

I must say the lid does lack character.
Will be working on some kind of labelling. Have got some clay left over, so maybe i can do something with them. Thought about some colour to finish, but ill be happy just to give it a name.

Re: Coretto cover project

Good work Gary, I was fairly confident that a clay lid would work when I suggested it
And as you said no tools required

I am disappointed that you did not sign or place a logo on the lid to make it unique

Re: Coretto cover project

As promised, here are some pics of the hand moulded clay coretto cover for the purpose of creating a "closed" environment, supposedly to create a sweeter tasting cup due to less effect from surrounding air, keeping the heat in to and retaining goodness.
For me so far, this project has been successful.
This can be accomplished by anyone who has limited equipment and know-how.
Just measure the dimensions of the breadpan, purchase some clay from their local craft shop, and then start working on it straight away.
The two main requirements after measuring and cutting, is to create two holes, one for heatgun, and one for exhaust. A handle is useful, but not really required if you dont want to.
The cover was thick and strong enough to hold the heatgun on its own without assistance, thus doing away with stand supports or ropes, chains et al.

I roasted a batch 3 days ago, have let it rest, and today tasted it.
Now i can taste more sweetness and more complexity in the cup. Somehow less brightness and acidity. All this from the first roast with a snakey line graph judging from the roast monitor and a slight stall of one minute between first and second crack.

Subjectively theres not a huge difference here from past cupping experience, but whatever differences are definitely noticeable. More chocolatey-malty aroma 3 days post roast, more definition in both fruitiness and sweetness. More body from the pour too. Enjoyable.

Perhaps some of you would like to join in and construct your own clay cover in the near future.
I think youll like it.

Now then, where did i put those fibreboards? Project 2 coming...

Re: Coretto cover project

Good looking outfit beanaround.
How did you find the flavour using that cover set-up? Was it better?

Mal, looking forward to the results of your project in due time, as well as your findings in the cup.

Update. I finally bought some clay designed for air drying.
Shaped and rolled it into a lid just to cover the breadpan. Made one hole for the heatgun, one hole for exhaust, and a handle for....handling.
Just for the heck of it, instead of air drying it, i stuck it on a cake rack and baked it in the oven at 200 deg celcius for hour and half. A nice result.
Today i tried it for the first time. The heatgun sat securely, and proceeded to roast 600gm of a blend, 17 minutes later, a even roast without any scorching nor tipping with a promising aroma filled the air.
Some chaff was left with the beans after dumping into the bean cooler, but they were easily dispensed by the exhaust fan after some stirring.

There was a snakey kind of line on the roast monitor graph as i was coming to grips on the different temps required for a "closed" system. In the excitement, i started with the highest fan speed instead of medium, so i had to adjust the temps up n down.
Hope to do a second roast soon, and tidy up the technique.
Photos coming tommorow. Cupping notes in a couple of days.
That was fun. 

On that same day i also went and bought some fibreboard, and will endeavor to start the second cover project, with more photos to come as well.

Re: Coretto cover project

Hi Mal, my coretto has an extension tube attached to the HG which goes down through the lid on the pan.

Gday Bean....

Yep, that looks pretty effective alright. 8-)

I was thinking with my setup, coming in from the back and lower down, as well as allowing the heat to be directed right into the bean mass, I could make the entire assembly more unitary and much neater. Im in no big hurry for this though, have to wait for my workshop to take shape first....

Re: Coretto cover project

Sure, back to the shed for more pics
This one is pretty rough, it was meant to be a quick prototype a year ago but it seems to have survived quite a few roasts while I tinker around with other things. It stays on the pan when I take it out to dump the beans but it just slides off and on for when I clean the chaff out of the pan. The aluminium flashing is very pliable and easy to work with, you just need tinsnips although you could probably cut it with a pair of scissors if you werent worried about making them blunt.

Re: Coretto cover project

Hi Beanaround,
Can you show more details of how you made your cover.
Looks like a practical solution!!!

Re: Coretto cover project

Hi Mal, my coretto has an extension tube attached to the HG which goes down through the lid on the pan. This can sit just above the beans if required. I would think that this gets the hot air in to the bean mass nearly as well as putting it in through the side like you wanted to do, but it doesnt involve much work. The tube is just a piece of aluminium flashing rolled up and held on with a hose clamp and the lid for the bread pan is made of the same flashing.
