Abstract

This invention relates to apparatus for lyophilising congealed or frozen product particles. Such apparatus usually comprises a box-like sublimation enclosure in which the particles are placed, and having bladed stirring means which are rotatable about an axis, together with heating means and filling and discharging conduits, one end of the discharge conduit being situated in an axial discharge zone and said conduit having an obturating member or shutter. According to this invention, the stirring means operates as a removal device in the lower part of the enclosure and has a flow gutter directed towards the said axial zone in the upper part of the enclosure. Discharge means situated close to the axial zone are also incorporated.
