Bread-based ethanol

crude vegetable oil, diester, bio-ethanol or other biofuels, or fuel of vegetable origin ...

Well no, I personally, I do not know and I have not managed to find much on Gogol on this subject apart from a cemetery and genealogy. Wouldn't you have a link or a bit of additional explanation?


Normal I was wrong in the spelling (it's Alsaco-German) apparently it would be: "bedelman"

The French name is "beggar" and here is the recipe (finally a recipe):

MENDIANT or bedelman recipe from my mother-in-law.

you take a large bowl and cut the stale bread into large pieces and soak it in warm milk (depending on the amount of bread) about 50cl
the bread should just be moist. Reduce it into a paste and add
3 eggs / cinnamon / custard powder or pudding
apples or raisins or dried fruit (as appropriate)
some schnapps and sugar
mix everything, sprinkle with breadcrumbs and butter and put in the oven at approx. 175 °

prick the cake it must come out dry


There are other uses of racis bread on http://www.isaveurs.com/forums/read.php?79,3379,3398

ps: in the same genre there is always the French toast but the bedelman is better !! Long live the recipes of grand mothers!

For stale bread, we give it, like others to a neighbor who has a small park, he gives it to his deer to eat.
it is very local, but this one is not lost for everyone. :D

but if we count on a yield of 5% for distillation (I am deliberately pessimistic) it's 1kwh spent to get 1l of ethanol which provides by burning 6kwh


Thank you for these small calculations (obviously distillation is not the only energy-consuming step in the production of ethanol ...).

Some questions :

1) How is the distillation yield calculated?
Energy absorbed by alcohol / energy supplied to the installation?

Does the condensation column enter the yield?

2) What are the usual yields of "distillers" (I don't even know the exact term ... help!) Artisanal and industrial?

in fact, your thing reminds me of the recipe for the preparation of beer in ancient Egypt (yes, that of the pharaohs)

Hi everybody,

I agree that producing too much food is not the most economical but this bread is already produced and is not used.
So it seems to me a little better to use it or for animals or possibly for alternative fuel, it is less worse? no ?

Glad to have seen your reactions, are there other novelties to replace this p.tain of petroleum? the kind you can do yourself?

Hope

I'm doing a little Up on this subject to answer all the questions !!!

I already introduce myself Loïck S. I belong to Du Lycée de Decazeville
We are the famous high school rolling on the bread E85!
I am also the student who had the idea of ​​bread ethanol!

Why?

Already you have to know or remember that the canteen bread (and other collective restaurants!) Not consumed is thrown away ... The midi bread can not be served in the evening and can not be given to a humanitarian organization ... (If it is the law !!!)

The idea came from a report on atré that the Egyptians made their beer with wheat ...

It also came from another fact .... Our school participates in this famous Shell Eco marathon for which we make our vehicle 98% (except the engine and the wheels)
Since 2005 The following high school sectors were involved in the Shell Eco project
-Plastics (bodywork manufacturing; pilot seat)
- Boilermaking (Cassis steering element)
-Tools (Steering knuckles, steering wheel, braking elements)
- Sewing (pilot and team combination!)

But only the Biotechnology section did not participate in the project
Since 2006 Thanks to the ethanol of bread she participates in it… and therefore the whole high school ie 600 students are involved in the project

For the manufacturing yes it will be possible to do it at home!

For the energy consumed Almost zero only an electric pump for distillation (because we use a solar still…)

For the recipe it is almost given on this same post! (Only the enzymes are kept secret by knowing which are in the trade ^^)

And NON Shell has by no means the recipe for manufacturing ... you should know that we use this ethanol only for our tests! Shell provides us with its beet ethanol shit (which shings and runs worse than that of bread) for ways of equity between teams!


Otherwise for the fact that the teacher did not answer it is simple it is not he who has the formula ^^

Basically remember this is a pedagogical project here that also saved the education of a lot of students !!!

Other questions ?
