Abstract: In a device particularly, but not exclusively, for preparing mixtures, for example, for dissolving dyes in powder form, and the like, in textile plants, the device comprises a tank which can receive buckets in which there is a product such as a pigment to be mixed with a vector, such as a liquid, which is supplied to the lower portion of the tank. At least one rotary turret associated with the tank has an arm on the free end of which there is a plate on which the buckets are deposited. As a result of a rotary movement about its axis followed by a lowering movement, the turret brings the bucket to a central position inside the tank which is closed at the top by a lid which can move vertically upwards and downwards. The rotation of the arm of the turret with consequent inversion of the bucket causes the pigment to fall into the tank in the bottom of which there is a mixer which brings about intimate and complete mixing of the product poured into the vector.

Abstract: The device enables a first component such as a mixture of powdered dyes to be dissolved intimately in a liquid solvent. To a slide movable vertically are attached a duct for making the liquid solvent flow into a basin in which the powdered mixture is located and a plurality of rotary whisks or helical agitator members able to dip into the solution so as to cause the intimate mixing thereof due to their rotation. The movable slide also carries a protective hood which surrounds the agitator members and the duct. After the solution has been taken from the basin by suction through the said duct it is possible to wash the basin and all the parts of the device which have come into contact with the solution in order to avoid contamination of a mixture intended to be prepared subsequently in the device.
