Device and method for mixing substances, mixing reactor and method for continuously ejecting a treated substance using said mixing reactor

A mixing reactor for mixing and continuous extrusion of a substance, comprising:

• a plurality of mixers,
• an extrusion press,
• a plurality of transfer cylinders,
• a press piston allocated to each transfer cylinder, which even during a transfer, forms a bottom of the transfer cylinder,
• a transfer vehicle for transferring the transfer cylinders, and
• a computer control for individually setting of mixing parameters, in particular mixing pressure, mixing temperature and mixing speed of each mixer,
• wherein the mixers and the extrusion press are connected to one another by the transfer vehicle, and wherein a substance to be treated may be transferred in a transfer cylinder from a substance filling-in position to the mixers, and to the subsequent extrusion press by means of the transfer vehicle, so that a finished mixture may be discharged from the extrusion press as a continuous product, and wherein the mixers comprise lower, transferable cylinders which correspond to the transfer cylinders and upper, stationary mixing cylinders, and wherein each transfer cylinder is equally distanced from an adjacent cylinder.

A method for the continuous discharge of a substance to be treated, with a mixing reactor comprising a plurality of mixers and a plurality of transfer cylinders, and each mixer comprises a lower, transferable cylinder which correspond to a transfer cylinder and an upper, stationary mixing cylinder, further comprising an extrusion press, wherein the mixers and the extrusion press are connected to one another by a transfer vehicle, the method comprising the steps of:

• a) filling a substance to be treated into a frontmost, first transfer cylinder;
• b) displacing all transfer cylinders, using the transfer device, by one position in a common direction, whereby said first transfer cylinder is displaced to a first mixing position and whereby further transfer cylinders are transferred to a further mixing position, and in the case of a last transfer cylinder, into an extrusion position;
• c) conveying a substance located in the transfer cylinders through a nozzle block provided with at least one opening, into an upper stationary cylinder by way of displacing a press piston allocated to a transfer cylinder, wherein the stationary cylinder is a mixing cylinder or in the case of a last transfer cylinder the stationary cylinder is an extrusion cylinder;
• and
• d) transferring all transfer cylinders back in a common, but opposite direction, and repetition of the steps a)-d);
• wherein during steps a-d each transfer cylinder is only displaced between two adjacent positions and
• a reaction temperature of a substance to be treated is set via a shifting of the boiling temperature of the substance, in that a mixer is set under a vacuum and said vacuum is set in a homogenization step, such that a reduction of the temperature of the substance corresponds essentially exactly to a temperature increase with one passage through a nozzle block.
