ABSTRACT:
An apparatus for the preparation of mixtures, especially dye solution. The apparatus includes a device for withdrawing a predetermined batch of product at a withdrawal station and for transferring the product to a separate dissolution station (SD). A device is provided for the dissolution of the product in the solvent, disposed in the dissolution station. A programmable electronic device is provided for operating the devices for withdrawal, transfer and dissolution of the product. The device for dissolution includes in a fixed horizontal plate with an annular seal housed in a corresponding channel of the lower surface of the plate making up a tight-sealing element for the mouth of a corresponding cylinder vessel containing the product to be dissolved. The vessel is associated with a vertical operating cylinder for driving the vessel from a lower to an upper position. A doctor blade is provided supported by a vertical shaft which is in a fixed spatial position and goes through a central hole of the plate to be supported by the latter. This vertical shaft is associated to a corresponding driving member for moving the doctor blade. A lump-breaking body is carried by a rod passing through a corresponding hole of the plate. The rod is associated to a corresponding driving member. One or more conduits with valves are provided for the supply of hot or cold water or other solvent into the vessel. An in-line pump is for the withdrawal of the solution from the vessel.
