An inline control and measuring system connected to a continuous mixing process of a system comprising an extruder for mixing solid or viscous materials with liquids and/or solvents to form the paste or viscous materials, wherein the paste or viscous material is discharged through a supply line and at least one outlet of a plurality of outlets, characterized in that the system comprises a bypass line branching from the supply line for receiving a volume of the paste from the supply line, wherein the bypass line comprises a plurality of pipes and a plurality of sensors, in that the system comprises a controller in communication with the extruder and/or the plurality of sensors in the bypass line, wherein the controller (i) receives signals of at least one of the plurality of the sensors in the bypass line, (ii) determines product properties of the paste based on at least the sensor measurements of the sensors in the bypass line, (iii) discharges the paste through the at least one outlet of the plurality of outlets based on the determined product properties, and (iv) controls the extruder and/or the pressure valve, when the determined product properties of the paste are different from target product properties, and in that the plurality of outlets comprises a first outlet communicated with a production line, wherein the first quality paste is discharged through the first outlet by being fed to a next production step, a second outlet communicated with the extruder, wherein the second quality paste is discharged through the second outlet by being fed back to the continuous mixing process via the extruder, and a third outlet communicated with a waste tank, wherein the third quality paste is discharged through the third outlet and collected in the waste tank. in that the system comprises a bypass line branching from the supply line for receiving a volume of the paste from the supply line, wherein the bypass line comprises a plurality of pipes and a plurality of sensors, in that the system comprises a controller in communication with the extruder and/or the plurality of sensors in the bypass line, wherein the controller (i) receives signals of at least one of the plurality of the sensors in the bypass line, (ii) determines product properties of the paste based on at least the sensor measurements of the sensors in the bypass line, (iii) discharges the paste through the at least one outlet of the plurality of outlets based on the determined product properties, and (iv) controls the extruder and/or the pressure valve, when the determined product properties of the paste are different from target product properties, and in that the plurality of outlets comprises a first outlet communicated with a production line, wherein the first quality paste is discharged through the first outlet by being fed to a next production step, a second outlet communicated with the extruder, wherein the second quality paste is discharged through the second outlet by being fed back to the continuous mixing process via the extruder, and a third outlet communicated with a waste tank, wherein the third quality paste is discharged through the third outlet and collected in the waste tank.
