Abstract

The mixing plant having a mixing tank (1) in which mixer arms (2) extend is distinguished by nozzles (3) which are directed in a specific manner at mixer arms (2) and also at the bottom and shell of the mixing tank (1), and are in flow connection with a compressed air source (4), and furthermore by at least one suction opening (6) in the mixing tank (1), which is in flow connection with a negative pressure source (5). This arrangement permits optimum rapid cleaning of the mixing tank after a mixing operation. <IMAGE>
