Chocolate refiner

The TECNO 3 refining line mod. P10S-CI, specially designed to continuously refine chocolate in a single passage, represents an important goal in terms of simplifed process, reduced space requirements and energy saving. The system consists in three grinding units in series, respectively a prerefiner with two horizontal rolls, a vertical roll refiner and a ball mill, in order to get a very fine granulometry, suitable for all types of chocolate. TECNO 3 has chosen the liquid conching technology, and its refining line is conceived to process the various recipes complete with all the ingredients. The initial chocolate mixture prepared in the continuous doser-mixer is sent into the two-roll pre-refininer via a pump. A screw feeder conveys it into the vertical roll system to complete the pre-refining and finally enters the ball refiner, where the final grinding takes place in a single, rapid and continuous step. The refined chocolate exhits the line in a liquid state, passes through a filter and is tranferred into the conche via a pump. The ball system plays a dominant role for the final result and its parameters, such as product flow rate, rotor speed, chamber temperature and pressure, that are controlled by advanced electronic logics, which guarantees a correct particle size distribution, with a Gaussian curve that is practically superimposable on the corresponding chocolate one, that is achieved with traditional methods. The TECNO 3 refining line mod. P10S-CI is entirely made of Aisi 304 stainless steel. The recipe parameters can be set on the touch-screen operator panel and managed by PLC.
