Title: Vacuum drier with successive vibrating plates - with plate sizes increasing progressively downwards to permit faster drying
Inventor: STAHL BERNHARD DIPL ING
IPC: F26B5/04
Filed: 1976-06-08
Abstract: A vacuum drier for particulate material comprises a vacuum vessel contg. spiral or plate-like surfaces one above the other, the material progressing gradually downwards. Some or all of these drying surfaces are larger than those above them. Pref. the surfaces increase continually in size, pref. in dia., down the vessel. The dia. of the largest may almost equal the dia. of the vessel. The surfaces may have a common vibrator or separate vibrators. Appts. is esp. used for freeze-drying. Higher drying rates, resulting in increased speeds of ascent of evaporated vapour, can be tolerated, because light particles entrained upwards by the vapour are caught by plates below as they fall again; this also results in lighter particles, esp. drier particles, reaching the bottom more rapidly by jumping several stages, whereas heavier particles move down more slowly.
