# Council Decision of 14 November 1992 laying down methods for the analysis and testing of heat-treated milk for direct human consumption (92/608/EEC), Division 4.2.2.2: Mixing of the contents of large vessels or of storage, rail or road tanks can be carried out:

Extent: E+W+S+N.I.

by a mechanical agitator built into the tanks and driven by an electric motor;
by a propellor or agitator driven by an electric motor and placed on the manhole with the agitator suspended in the milk;
in the case of rail or road tankers by recirculation of the milk through the transfer hose attached to the tanker unloading pumps and inserted through the manhole;
by clean filtered compressed air. In this case, minimal air pressure and volume should be used to prevent the development of rancid flavour.
