(57) Device for the quick hooking and unhooking of wire meshes support frame in vacuum
driers including at least a plane (12) to support the article to be dried cooperating
at the upper part with a cover (14) which can be moved from a lowered, closed position
(14a) to a raised position (14b) wherein the article is loaded/unloaded, the cover
(14) supporting at least a first frame (29) supporting a covering sheet (30) defining,
in the first, lowered position (14a), an air-tight chamber (23) with the supporting
plane (12), the cover (14) supporting, below the covering sheet (30), at least a wire
mesh element (19a, 19b) or similar or comparable element suitable to allow the passage
of liquids and/or humidity in vapour form, the wire mesh element positioning itself
in the working position in contact with the article to be dried, the wire mesh element
(19a, 19b) being associated with a second, autonomous frame (17) including a second,
inactive position (17b) at least partly remote from the cover (14) although connected
solidly thereto, in the inactive position (17b) both faces of the wire mesh element
(19a, 19b) being visible and easily accessible for cleaning, maintenance and/or replacement
of the wire meshes (19a, 19b).
