Industrial Extraction is the process by which harmful air contaminants are removed from the work place for the protection of employees and the environment. [1]In the UK, the Health and Safety Executive has implemented COSHH regulations to ensure all industrial workplaces protect the health of their employees via effective Local Exhaust Ventilation (LEV).

Some high-boiling liquids that have an azeotrope with water can be dried by adding toluene or another azeotrope-breaking solvent to allow the extraction of water. The Dean–Stark method is commonly used to measure moisture content of items such as bread in the food industry. This equipment can be used in cases other than simple removal of water.
Joseph H. MacNeil, Professor of Food Science at Penn State University, developed a machine that uses a delicate multi-bladed knife to scrape the membrane from the surface of shell fragments. [7] This invention uses a water-based method to separate the eggshell and protein membrane. The two products are processed in two streams to yield mm size ...

Vanilla extract. An extract (essence) is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol, oil or water.Extracts may be sold as tinctures or absolutes or dried and powdered.
For truly stubborn food on the surface, boil water in the pan, then repeat the paste method. Remember, too, that cleaning the enameled cast iron promptly after cooking and after it has cooled is ...
It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve ...
Decanting a liquid from a solid. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.
