The present invention is referred to a refiner / mixer(16) of products for the food industry, pharmaceutical industry, and the like, with a precise and continued control of the physical / chemical parameters of refining / mixing, at low energy consumption, with integrated cooling means (19) and washing means (20), with sensorized electronic control, to be directly installed in a production line without stock of the production, to produce in a continuous way a refined / mixed pasty substance, so to obtain a very fresh and controlled product, in which the temperature of the refined / mixed pasty substance is continually controlled during the advancing of the refining / mixing, to not exceed the pre-defined limit values, that, if exceeded, will cause a qualitative decrease of the refined / mixed pasty substance.It is a refiner / mixer that has in-line granulometric controls (86,87) and in line metal-detector means (90,91), and that consequently does not release metal contaminations, and that permits to chose the feeding position of the products, so to produce innovative products otherwise not producible, engineered to be assembled in a quick and economic way in base of the specific quantity of production required by the customer, and that comprises self-learning and self-adjusting software.
