Evaporators | Dairy Processing Handbook

Heat treatment is often an integral process step of an evaporator in order to achieve specific properties in the finished powder. As some products are sensitive to heat, the design of these systems has to be considered carefully with respect to temperature and holding time in order to achieve the desired effects on the one hand, but without causing heat damage on the other.

Table of material properties for structural steel S235, S275, .

 · The fracture toughness of steel is characterized in EN in terms of the KV (T) value the impact energy in Joules [J] required to fracture a Charpy Vnotch specimen at a given test temperature T. Subgrade JR correspond to a minimum KV of 27 J at Room temperature (+20°C). Subgrade J0 correspond to a minimum KV of 27 J at 0°C.

Titanium

Titanium is not as hard as some grades of heattreated steel; it is nonmagnetic and a poor conductor of heat and electricity. Machining requires precautions, because the material can gall unless sharp tools and proper cooling methods are used. Like steel structures, those made from titanium have a fatigue limit that guarantees longevity in some appliions. The metal is a .

Hydrochloric Acid Handbook

Hydrochloric acid is used primarily for continuous pickling operations in which hotrolled strip steel is passed through a countercurrent flow of acid solution. In addition to steel pickling, hydrochloric acid is used in aluminum etching, metal prefixing for galvanizing and soldering, and metal cleaning. Oil well acidizing

Frontiers | Pasteurization of Beer by NonThermal Technologies

The pasteurization of beer occurs at the end of the industrial production, after fermentation. Generally, a mild thermal process (60°C) is employed aiming to inactivate the fermenting yeast and potential spoilage microorganisms, thus extending the beer shelflife at room temperature. The heat treatment negatively affects the original beer freshness and flavor. In this study, .

Metallic grain structures and microscopic analysis insight

For example, microscopic analysis can be used to evaluate characteristics in the metal design and processing stages, as well as cases in which damage has occurred.
