Membrane technology covers all engineering approaches for the transport of substances between two fractions with the help of semi-permeable membranes. In general, mechanical separation processes for separating gaseous or liquid streams use membrane technology. In recent years, different methods have been used to remove environmental pollutants ...
Food technology. Food technology is a branch of food science that addresses the production, preservation, quality control and research and development of food products. It may also be understood as the science of ensuring that a society is food secure and has access to safe food that meets quality standards. [ 1]
Aseptic processing is a processing technique wherein commercially thermally sterilized liquid products (typically food or pharmaceutical) are packaged into previously sterilized containers under sterile conditions to produce shelf-stable products that do not need refrigeration. [ 1] Aseptic processing has almost completely replaced in-container ...
Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing takes many forms, from grinding grain into raw flour, home cooking, and complex industrial methods used in the making of convenience foods. Some food processing methods play important roles in reducing food waste ...
Taking an example from the food processing industry: Fluidized beds are used to accelerate freezing in some individually quick frozen (IQF) tunnel freezers. These Fluidized bed tunnels are typically used on small food products like peas, shrimp or sliced vegetables, and may use cryogenic or vapor-compression refrigeration. The fluid used in ...
This is the working principle of many hydrodynamic cavitation based reactors for different applications such as water treatment, energy harvesting, heat transfer enhancement, food processing, etc. [8] There are different flow patterns detected as a cavitation flow progresses: inception, developed flow, supercavitation, and choked flow.
Fluidization. Fluidization (or fluidisation) is a process similar to liquefaction whereby a granular material is converted from a static solid -like state to a dynamic fluid -like state. This process occurs when a fluid ( liquid or gas) is passed up through the granular material. When a gas flow is introduced through the bottom of a bed of ...
Cryogenics. Nitrogen is a liquid under −195.8 °C (77.3 K). This is a diagram of an infrared space telescope, that needs a cold mirror and instruments. One instrument needs to be even colder, and it has a cryocooler. The instrument is in region 1 and its cryocooler is in region 3 in a warmer region of the spacecraft (see MIRI (Mid-Infrared ...
