Volumetric dosing device for dosing friable product from beaker has compressed air outlet above beaker to blow contents out downwards when closing device is opened

摘要

The device (1) doses a friable product from a beaker (2). Compressed air is supplied to the beaker from above, so that the product portion in the beaker passes more rapidly through an aperture (4) in the floor of the beaker when the closing device (15) is opened. The compressed air is generated by a compressor (8), and can be supplied in pulses.
