METHOD OF COOLING A TORREFIED MATERIAL

The invention relates to a method and a system for efficient cooling of torrefied material which also increases energy yield and hydrophobicity of the torrefied product and decreases clogging of the cooling device. The method includes that at least a part of cooled torrefied material is mixed-back w...

Zusammenfassung:	The invention relates to a method and a system for efficient cooling of torrefied material which also increases energy yield and hydrophobicity of the torrefied product and decreases clogging of the cooling device. The method includes that at least a part of cooled torrefied material is mixed-back with hot torrefied material before the hot material is introduced into a cooling device for further cooling of the torrefied material. Cette invention concerne un procédé et un système pour le refroidissement efficace d'un matériau torréfié qui accroît également le rendement énergétique et l'hydrophobie du produit torréfié et réduit l'encrassage du dispositif de refroidissement. Le procédé selon l'invention comprend au moins une étape consistant à re-mélanger au moins une partie du matériau torréfié refroidi avec le matériau torréfié chaud avant que le matériau chaud ne soit introduit dans un dispositif de refroidissement pour un refroidissement supplémentaire dudit matériau torréfié.
