Description
DESCRIPTION OF AND METHOD FOR PRODUCTION OF HYBRID ENERGY PELLETS
DESCRIPTION
The world is currently focused on the global warming crisis and the development of carbon neutral fuel sources. This invention not only produces a carbon-neutral hybrid energy pellet, it also diverts waste agricultural and/or forestry material from the waste stream and creates a product that can be used for energy production. Using bio-oils such as those derived from plants and animals (e.g.
new vegetable oil, refined used vegetable oil, animal fats, etc.) in this process allows for virtually total use of the oil versus historical usage for biodiesel production which by conventional use only uses 60% of the total weight of material because the unwanted soaps and other delirious substances are discarded.
While the production of energy pellets is not a new technology, hybridizing the pellets by adding a small amount (+/- 10%) of the aforementioned bio-oils before the pellet is extruded and then deep-frying the pellets in bio-oils to torrefy* them into pelletized biological charcoal is a new invention.
*Torrefaction is the process of converting the wood/agriculture fibre (Biomass) pellets into pelletized biological charcoal.
Torrefying the pellets in bio-oil increases the BTU value of the material by two factors:
1. The bio-oils increase the BTU value of the pellet by absorption of the oil by the fibre that has been pelletized.

Using bio-oils such as those derived from plants and animals (e.g.

*Torrefaction is the process of converting the wood/agriculture fibre (Biomass) pellets into pelletized biological charcoal.
Torrefying the pellets in bio-oil increases the BTU value of the material by two factors:
1. The bio-oils increase the BTU value of the pellet by absorption of the oil by the fibre that has been pelletized.
2. The torrefaction process removes all the moisture, thus increasing the BTU
value of the pellets as well.
This improvement to the pelletizing process virtually eliminates fine wood particles or dust that would otherwise be created after the pellets are extruded because the bio-oil creates a binding agent for the material that precludes the creation of these dust particles during the pelleting process.
This product can be used to generate heat in residential or commercial pellet stoves and/or other industrial use such as energy creation or bulk heating applications.
Process description:
Combustable biological material such as Wood fibre and/or Agriculture fibre is introduced in a conditioning chamber(1), there the material is put through a hammer mill(2)and reduced to material less that one quarter inch in diameter.
The material is then passed by conveyor(3)to a secondary conditioning chamber(4) where refined used vegetable oil, new vegetable oil or animal fats that have been heated to approximately 200 0C is added by spray method(5) then mixed mechanically(6) to reach a uniform consistency. The material is then put through a mechanical extruder(7) to extrude pellets in 6 mm to 10 mm diameter form. The extruded pellets are forwarded to a 200 to 300 C hot oil tank(8), submerged and cooked until the pellets are torrefied. Once torrefaction is reached the pellets will be put across a horizontal screen (9) so any excess oil is recovered and put back into the hot oil tank. The torrified pellets are then transferred to a cooling tower(10) where they will cool and harden. After the cooling process the pellets will be packaged (11) either in Bulk or bagged form depending on what the designated market may be.
