Abstract (en)
[origin: EP0118682A2] Foam (15) is produced continuously by mixing water with a foam former (32), in particular shampoo, and feeding air into this liquid mixture (12) of water and foam former (32), which is placed into a liquid tank (10) level-controlled by means of a float switch (13) for resupply in accordance with consumption. Compressed air is introduced as required into the liquid mixture (12) for foaming, and foam (15) is thereby produced in the liquid tank (10) above the level of the liquid mixture (12). The water is fed in a separate water feed line (20) at the set pressure and/or rate. In the same way, the foam former (32) is fed in a separate feed line (30) at a metered rate by means of a metering pump (33), and water and foam former are mixed in the liquid tank (10) or before they are introduced. The float switch (13) controls the feed of water and foam former (32) as a function of the liquid level (14). In a separate feed branch (40) compressed air is introduced into the liquid mixture (12) in the liquid tank (10) whenever foam (15) produced is taken off, and the mixture is whirled up, forming foam (single figure). <IMAGE>
