The cooker is made entirely in stainless steel, with insulated tank and a gap to allow the cooking by circulation of oil with controlled temperature. The central mixing tool has side and bottom scrapers, to prevent the product from sticking to the tank. The cooking is quick and homogeneous thanks to the stainless-steel armoured electric resistances with adjustable power. The temperature is controlled by an electronic thermostat, and a timer with acoustic signal controls the duration. The product removal is made easier by the use of levers that control the tank rotation.
