Abstract

Lyophilization apparatus comprising an airtight chamber, at least one tray for the frozen product to be dried, at least one inlet of said frozen product in the chamber, opposite one of the ends of the tray, at least one outlet for the product dry of said chamber, in front of the other end of the tray, means for heating the product on said tray to cause sublimation of the ice, an installation to reduce the pressure inside said chamber, means for vibrating the tray in view to obtain a displacement of the product from one end of the tray to the other, and an installation to evacuate from said chamber the vapors due to sublimation, characterized by the fact that it includes cooling means for the vibrators.
