Diagram manufacturing plant pellets pellets

Following this message https://www.econologie.com/forums/post62604.html#62604 and to introduce a subject concerning the manufacture of granules or pellets (or briquettes) wood here is a diagram of the production line:

Shema is a somewhat simplistic process but already outlines.


It must be remembered that the sawdust once dried is to be crushed and homogenized to have a grain size> 4mm.

After being passed to the press, just tt manufactured granules are about 80 ° C, need to be cooled before being sort of dust and stored.

As regards the heat source downstream of the dryer, many solutions exist, just like for the dryer which in the case of factories dedicated to the production of pellets are often so-called "low temperature" dryers which are not "rotary drum" type dryer as in the diagram.

In short if you have technical questions, the extent of my knowledge qq, I would answer with pleasure.

Hello !

Yes me that interests me! I am working on a "Wood Engine" project at the IUT of Nantes and I would like a little more information on the heat treatments of the chips, or the sawing before the passage in the pellet mill. What types of dryers are used? Belt dryers ("Kahl") or others?

In fact it is to make a rapid assessment of the energy cost of pellet production. Not something precise great but have an order of magnitude of this embodied energy!

Thank you for your help.

Bonjour à tous

Matos I quote:

it also interests me.

Are there very low-energy process?

Hello,
I see that the post is inactive for a long time but I still have questions!
know you reliable equipment to make sawdust-based pellets, straw or miscanthus small scale?

on the net, I find reka offering of undue or non-branded presses and for which there is little information

hellos
had for pellet presses I found it but it's the chinoix gear
his gives an idea of ​​prices for qualitée ???????
is that I was not hurt c was the idea of ​​mini portable factories and the press not very expensive
I thought making pellet from straw or willow wood
but for the moment draft lease booth

There is an Alsatian company (expensive plus the name) which sells "micro presses" I do not know if it is Chinese (but considering the price that would not surprise me).

This is the one that you had contacted?

[greg]

small mobile unit, that is what interests me
I found a model in oliotechnology:

they are in 67, the you know?
