The pyrolyzer Spirajoule®
The Spirajoule® technology is an exclusive process for thermal treatment. It is designed with a low voltage electrically heated worm screw conveyor. The screw heats the product as a result of the joule effect. The product temperature is precisely controlled based on the heating screw temperature setting; the dwell time is regulated by screw rotation speed setting.
Biogreen® is an innovative process for optimizing energy consumption.
The pyrolyzer has an electronic temperature regulation and is quickly heated by electricity (Spirajoule®, patented technology) to the nominal operating temperature for torrefaction or pyrolysis. The product to be treated is then introduced into the pyrolyzer.
Depending on its Low Heating Value, the product will immediately reach operating conditions for an exothermal reaction. This reaction will then be maintained at the nominal temperature of the pyrolyzer during production and electrical energy consumption will stop. However if for any reason, the feeding condition changes (more moisture or flow rate), the internal temperature will decrease and the electrical energy supply will restart automatically to maintain the power needed to reach the nominal operating temperature.
This allows Biogreen® to guarantee a perfect and constant quality of the product obtained from the treatment.
