Mixing Tank- Raw ingredients, such as fresh or powdered milk, water, vegetable oil or butter-fat, sugar, stabilisers and emulsifiers are introduced into the stainless steel tank and blended with rapid agitation. The alternate use of the two mixing tanks ensures a continuous production process. The heating system supplies hot water via the circulation pump. Then the mix is heated to 55°C by means of hot water in the jacket. The alternate use of the two tanks ensures a continuous production process. Once the temperature is reached the mix is transferred to the balance tank via a centrifugal pump.
