CEBCON PELLET CONDITIONER/ -COOLER WITH HEAT RECOVERY

Outstanding energy efficiency, flexible design and increased fire safety: CEBCON has developed an innovative pellet cooler featuring an efficient heat recovery system for use in the pellet production process.


CEBCON has developed an innovative pellet conditioner and cooler that features an energy-efficient heat recovery system for use in pellet production. Depending on the selected design, the conditioner/cooler can process granulates from a variety of biomass. This includes pellets made from:

  • By-products from the forestry and timber industry, sawdust, logs
  • Agricultural waste such as straw, shells, husks
  • Solid fermentation residues from biogas production
  • Whole plants such as bamboo, miscanthus,
  • Wood from short-rotation plantations
  • Animal excrements


The conditioner/cooler can be implemented either as an integrated component for new pellet production facilities or as a stand-alone module to replace existing facilities.

The innovative CEBCON pellet conditioner/cooler improves efficiency in pellet production, increases operational safety and achieves significant cost reduction. In addition, thanks to its special design as a containerised system, it increases flexibility: This facilitates transport and assembly, while reducing the amount of space required.
Due to the special arrangement of these cooling elements, the wood pellets or other solid pourable material are cooled particularly effectively and gently,  while avoiding dust formation and large quantities of exhaust air.

ADVANTAGES OVER CONVENTIONAL COOLERS:

  • Special design features of the conditioner/cooler enable very efficient operation compared to conventional coolers. The principle of contact cooling leads to a higher and stable quality of the pellets due to the gentle cooling and hardening of the pellets, while reducing pellet-abrasion, avoiding dust formation and exhaust air.
  • During conditioning, no additional excessive drying of the pellets takes place. The water content remains almost stable, which allows the pellet products to be better adjusted to an optimal target water content.
  • The recovered heat of 91 kWh or approx. 600 MWh/a (assuming 6,500 production hours per year and a press capacity of 4 to/hour) can be used for drying and conditioning the raw material before pressing.
  • Maintenance costs are also reduced due to the design features. Fabric filters and large fans can be dispensed with Because of the few moving parts, the wear and the risk of failure, as well as the operating expenses are low.
  • In addition, the cooler is safer to operate as a result of the avoidance or minimisation of explosion and fire risks during cooling. The risk of fire is negligible compared to conventional air coolers.
  • And finally, the pellet cooler is flexible and easy to use: It is equipped with necessary temperature and level sensors as well as control technology and can be integrated into the upstream plant control system for automated operation. In addition, the cooler is designed in standard container format, which reduces the transport and installation costs. Pre-assembly and testing are carried out at the factory before delivery to the customer: These result in a shorter assembly time (by up to 80%) and accelerated commissioning.
