摘要

Apparatus for cleaning a cylindrical mixing vessel 1 (see Fig 1, not shown) comprises a rotating axial shaft 2 carrying mixing or other tools 5 on radial arms 4; the shaft 2 has a bore 10 through which compressed air or other gas, or liquid, can be supplied to nozzles 14 mounted on the arms 4 and directed at acute angles to the inner surface of the vessel and to the discharge opening 6. The nozzles are preferably helically arranged round the shaft. There are additional nozzles 17 on those arms nearest to the end walls of the vessel. The apparatus may also be used for moistening materials, or for drying them with hot air.
