Patent DE-2025243-A1 (DE)
Title: Continuous freeze-drying with high efficiency - and effectiveness
IPC: F26B5/06
Filed: 1970-05-23
Abstract: Apparatus for freeze-drying food and medical products comprises a lower central stationery duct connected to an upper central duct which rotates together with a turn table. Ducts branch from the upper duct to the turn table and short ducts join them at the table. Containers, of a material with low dielectric loss factor, are detachably capped on these short ducts and a horizontally circular locus as carried on the table. The containers are guided vertically along the locus and are detached from the ducts during the first part of the circle. During this part the ducts engage a frozen object. The lower duct is connected to a vacuum pump, to exhaust the short ducts and the container. While exhausted the container runs through a tunnel equipped with high frequency oscillators and shielding means to provide an electric field in which the object is heated to sublime frozen moisture. The container then regains atmospheric pressure. There is no danger of electric discharge in the vacuum and no need to enlarge the vacuum container size.
