1. System for producing and propelling solid sublimable particles, said system comprising at least:
- a first means for producing solid sublimable particles;
a second means connected to said first means, said second means receiving solid sublimable particles produced by said first means and propelling said solid sublimable particles towards an outlet, and at least one duct extending between the first means and the second means for conveying solid sublimable particles produced by the first means to the second means, in which the first means for producing solid sublimable particles comprises at least;
a container with a first opening and a second lower opening associated to a cutting plate, said first opening being adapted for placing sublimable material in the container above the cutting plate, means for driving into rotation the cutting plate, and a funnel attached to the container, said funnel having a lower end connected to the duct conveying the solid sublimable particles to the second means, and an upper end, at which the cutting plate forms a separation between the funnel and the lower opening of the container, whereby the cutting plate has a lower face directed towards the funnel and an upper face intended to be directed towards the sublimable material placed in the container and is provided with at least one line of cutting teeth, each cutting tooth being associated to at least one passage extending through the plate, whereby, when the cutting plate driven in rotation contacts sublimable material placed in the container, the cutting teeth are adapted for producing solid sublimable particles with an average weight size smaller than about 6 mm, said solid sublimable particles passing directly through the cutting plate into the funnel.

11. Method for treating at least one face of an object by blasting sublimable particles on said face by means of a system comprising at least:
-
a first means for producing solid sublimable particles;
a second means connected to said first means, said second means receiving solid sublimable particles produced by said first means and propelling said solid sublimable particles towards an outlet, and at least one duct extending between the first means and the second means for conveying solid sublimable particles produced by the first means to the second means, in which the first means for producing solid sublimable particles comprises; a container with a first opening and a second lower opening associated to a cutting plate, said first opening being adapted for placing sublimable material in the container above the cutting plate, means for driving into rotation the cutting plate, and a funnel attached to the container, said funnel having a lower end connected to the duct conveying the solid sublimable particles to the second means, and an upper end, at which the cutting plate forms a separation between the funnel and the lower opening of the container, whereby the cutting plate has a lower face directed towards the funnel and an upper face intended to be directed towards the sublimable material placed in the container and is provided with at least one line of cutting teeth, each cutting tooth being associated to at least one passage extending through the plate, whereby, when the cutting plate driven in rotation contacts sublimable material placed in the container, and whereby the cutting teeth are selected so as to form sublimable particles with an average weight size of less than about 6 mm, said method comprising the step of; introducing solid sublimable material in the container whereby said sublimable material contacts the upper face of the cutting plate provided with the cutting teeth;
driving into rotation the cutting plate so as to extract solid sublimable particles from the solid sublimable material present in the container;
said solid sublimable particles passing through the cutting plate into the funnel and falling in the duct conveying the solid sublimable particles in the second means for propelling said particles towards an outlet,expelling solid sublimable particles from the outlet towards the object to be treated. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
