Handling of Materials in the Food Industry

The liquid state is, undoubtedly, of utmost importance in the material processing industries, including the food industry. Numerous raw materials and products are in liquid form in a variety of processes. Liquid foods, such as milk, honey, fruit juices, beverages, and vegetable oils, are handled at different stages in food processing lines. More consistent food materials, such as salad dressings and mayonnaise, may also behave somewhat like liquids. There are many important properties of liquids to deal with, such as thermal conductivity and specific heat. However, the most relevant are those related to flow since most liquid foods are mainly conveyed and pumped, so their flow behavior properties are important for determining the power requirements for pumping or the sizing of pipes. The transport of liquid foods by pumps and other relevant applications in processing are directly related to their properties, especially density and viscosity.
