Batch cooker consists of specifically designed rotor and paddles.  Cooker gets a smooth start up with a counter measure against heavy loads from a reductor with a two way rotating engine and ‘V’ shaped pulley which is tied to its hydraulic coupling output. Cooker’s body is designed with a steam jacket. The rotor has a rotatory steam nozzle attached. The nozzle emits steam into the rotor itself. The rotor is supported by heavy duty bearings from both sides and the rotor mill prevents leakage with the adjustable gasket. 10 Bars of steam jacketing and 5 Bars of body pressure is applied.
