Abstract
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.
