Method and apparatus for the pneumatic conveying of milk powder

摘要

Milk powder, or similar powder which is liable to smear when under mechanical stress, is conveyed in sucessive plugs or batches in a suction flow which is interrupted at intervals according to the batch size. In apparatus for this purpose, an interval-controlled valve is provided in a suction conveying conduit which is connected via an inlet chamber to the outlet of a container for the powder. The container may have at its outlet a loosening floor operable with pulses of compressed air controlled synchronously with said interval-controlled valve.
