Mixing of the content of large vessels or of storage, rail or road tanks can be carried out:
- 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.
