Abstract

1282702 Freeze drying apparatus NESTLE'S PRODUCTS Ltd 20 Jan 1970 [20 Feb 1969] 2617/70 Heading B1B [Also in Division F4] A vibrator cooling system in a freeze drying apparatus of the horizontal vibrating sublimation tray type comprises a hollow plate attached to each vibrator having cooling fluid inlet and outlet tubes 72, 82 adjacent to opposite sides of the plate and having labyrinthine deflectors 91, 92, 93, 94. In another embodiment the vibrators are cooled by fluid circulating between their casing and a mantle surrounding the latter.
