Moreover, the water content (water content) of the residue can be reduced, and the fuel efficiency can be greatly improved when the residue is diverted to fuel. In addition, the residue can be miniaturized. Therefore, it has industrial applicability.

Abstract

La présente invention comporte : un rouleau inscrit (3) qui est disposé de façon à pouvoir tourner ; un rouleau annulaire rotatif (2), qui est disposé de telle sorte que le rouleau inscrit (3) est disposé dans une partie d'espace formée à l'intérieur de celui-ci, et que la distance de centre de rouleau à centre de rouleau à partir du rouleau inscrit (3) est variable ; des moyens de rotation de rouleau inscrit qui font tourner le rouleau inscrit (3) ; un rouleau de pression (4) qui est disposé à l'extérieur du rouleau annulaire (2) et qui presse la surface périphérique externe du rouleau annulaire (2) ; des moyens de réglage (33A) qui font se déplacer l'un par rapport à l'autre le rouleau inscrit (3) et le rouleau de pression (4) dans une direction dans laquelle les rouleaux se rapprochent ou s'éloignent l'un par rapport à l'autre de façon à régler ainsi la distance de centre à centre entre le centre de rotation du rouleau inscrit (3) et le centre de rotation du rouleau de pression (4) ; et des moyens de rotation de rouleau annulaire qui font tourner le rouleau annulaire (2). Un objet inséré qui a été disposé dans la partie d'espace du rouleau annulaire (2) est directement écrasé par la surface périphérique interne du rouleau annulaire (2) et la surface périphérique externe du rouleau inscrit (3) entre la surface périphérique interne du rouleau annulaire (2) et la surface périphérique externe du rouleau inscrit (3).
