Spirajoule: Electrically heated screw conveyor
Spirajoule is eletrically heated screw conveyor proven for 20 years in industrial operation. Technology allows perfectly controllable, thermal processing of organics and minerals.
Continuous heating of organics and minerals
Spirajoule® is an exclusive and patented thermal treatment process which is the unique combination of 2 fundamental inventions: the endless screw conveyor and the heating resistance.
It is a dedicated equipment for a continuous thermal treatment in temperatures up to 850°C, basing on a hollow shaft screw conveyor heated by a low voltage current. The screw is made from electrically conductive material and is connected to an electricity power supply.
Electricity is conveyed from the power supply by the specially design components located at both sides of the screw. The passage of electronic current through the conductor (screw) generates heat, which is as a result of Joule heating (also known as Ohmic heating or resistive heating).
Why Spirajoule?
Simple = Easy to use technology
Performance = Energy efficiency by kilo of treated feedstock
Innovative = Dozens of possible applications through this electrified screw conveyor
Robust = Strong manufacturing with high quality material that are lasting for years
Adaptable = Any kind of non-ferrous and dry material could be treated
Joule = using Joule effect, allowing temperatures from 20 to 750°C
Optimized = A heating management optimized by 30 years of return of experience
Useful = Continuous concept, capable of running 24/7
Low Maintenance = Low rotation speeds imply low stress on mechanical parts
Electrical = Fossil-free technology
Thermal treatment under a perfect control
Thanks to its features, Spirajoule® is an equipment proposed for all types of bulk products treatment: from food industry, through chemical, petrochemical, up to the waste industry sectors. The electrically powered screw heater provides accuracy and efficiency not achievable by other means. Processing is possible in adapted, oxidizing, reactive or inert atmosphere achieved by coating with selected gases. Spirajoule allows heating materials exclusively by electricity, allowing to carry the process without difficulties related to burning conventional, fossil fuels and off-gases generation. Equipment can be powered exclusively from clean, carbon-free sources if needed.
Industries served
Whether applied in the food industry, valorization of waste or chemical processing, Spirajoule is an equipment that can be engineered around the application and well adapted to the needs.
