Automatic Granulation Line

The Ll110 granulation line stands out from the usual granulation processes, thanks to its exclusive technology implemented and patented by Oliotechnology. This makes the Ll110 granulation line one-of-a-kind. This new process is based on biomass dehydration as opposed to extrusion, as with all other pellet producers. An expert in the domain has shown this new method to produce, on average, 200kg (441 pounds) of granules per hour.

But this line doesn't stop there. This innovative process also offers the great advantage of drying as it transforms.


The traditional method, by contrast, does not allow for materials beyond 12% moisture and thus requires a separate drying stage which requires a huge amount of energy.
The LI110 system allows the granulating of material up to 25% humidity, with the final granule being less than 10%. (A significant amount of steam is given off during the process. We're working constantly on improving our humidity limits even more.)
Also, there is no need to have a steam generator to soften the material, and thus no need either for a cooling system as the pellets come out. These two steps require a significant amount of energy—which can be avoided with the LI110.
Moreover, the granulation process of the LI110 does not demand as much pressure as with the traditional method, because it is more than a simple extrusion system. This leads to even more energy savings.
Thus, at the same level of production, the LI110 requires far less energy than the traditional granulation systems that are used all around the world.
The line is also more compact (about 30m2 - 98 squared feet - on the floor), and thus less expensive.
It is important to note that the savings highlighted here have not reduced the system's ease of use, and that the line still allows the easy granulation of many different kinds of materials.

Tested biomasses (no binder needed):

- tevery wood species, even the hardest
- bark
- hay
- straw husks
- flax straw
- miscanthus
- reeds (phragmites)
- coffee bean chaff
- corn cobs

Several automations (Leroy Somer) control the line and enable it to work automatically. Once the machine is turned on and programmed – which takes about 10 to 15 minutes – no human intervention is needed. It is completely independent. Of course, it is possible to take control of each individual component at any given moment. This can be done by using the LCD menu of the electrical panel.

The granulation process happens through the following seven steps:
- The material enters via a container with a treadmill.
- From the treadmill, the shredder/refiner reduces the wood scraps, chips, etc. to coarse particles that are calibrated at 8mm (0.3 inches)
- These particles continue to a hammer mill with the aid of an initial blower. The mill's purpose is to pulverize the particles in order to end up with a thin and homogeneous dust.
- A second blower propels this dust towards a collector where gravity makes it fall into the pelletizer. Within, the air expelled is micron-filtered.
- The pelletizer transforms the material into pellets and dries it.
- The granules arrive to a vibrating sieve at a temperature of 70°C to 80°C (158°F to 176°F). The sieve filters potential dust and, thanks to the aspiration ventilation system, brings the pellets back to room-temperature.
-At the end, the pellets produced have a density much higher than a ton.
- Various bar graphs simplify considerably the use of the line.

The production of one ton of pellets made from wood shavings requires less than 15€ of electricity! Thanks to this technology, the local production of pellets is now far more profitable than industrial production. 30 million households could be heated in Europe solely with this wood that is deemed worthless!

This technology also allows to develop the planting and the granulation of miscanthus, which will be the energy of the future.

No line in the world is as economical – in both buying and operating – as the LI110. Moreover, the final pellets have a better density and a better compaction than any other.
