  • Milk is the result of milking a cow or other breastfeeding animal, which can be eaten or can be used as a safe and healthy food and is not minus its components or added other ingredients. In addition, milk has the characteristics easily damaged compared with other livestock products. Overcoming the above problems, easily damaged milk is usually processed into products that are more durable / resistant in a relatively longer time to be consumed. One of dairy products is cheese. Based on the calculation with the mathematical approach of the machine design of the cheese curd capacity of 100 kg / process, the specification of cylindrical reservoir body with diameter or D = 0,5238 meters and height of container or t = 0,4642 m with 1 atm working pressure and requirement the heat needed to cook milk is 218171,0571 kJ. The required heating power is 242,4122 kW. Dimensions of fin obtained length = 0.1964 m, height = 0.15 m. The total force received by the fin is 34.5425 N with the total number of fins is 3. The obtained motor power is 203.523 watts. In the heating process of this machine should be selected material that has the character of heat resistance and corrosion resistance for it selected material Stainless Steel AISI 304 with shear stress material 1.075 x 108 N / m2. Because the material stress occurs less than the material voltage then the material is appropriate for use.
