Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying media; however, if the liquid is a flammable solvent, such as ethanol or the product is oxygen sensitive nitrogen is used.

Clevenger Apparatus The most scientific term that used to get essential oils from plants wherever the essential oils found (stem, root, leaves, buds, seeds) is extraction. The steam distillation is the most well-known technique for extracting essential oil from plants, there are several other methods that are used to remove and concentrate the aromatic constituents from plant materials. It is a brief description method and their influence on the aroma therapeutic properties and fragrance of the oil. Clevenger hydro-distillation (laboratory technique with limited biomass and water and with cohobation). The oil is separated directly from the Clevenger apparatus.

Solid Liquid Extraction Unit Solvent extraction is usually used to recover a component from either a solid or liquid. The sample is contacted with a solvent that will dissolve the solutes of interest. Solvent extraction is of major commercial importance to the chemical and biochemical industries, as it is often the most efficient method of separation of valuable products from complex feedstock’s or reaction products. Some extraction techniques is involved in partition between two immiscible liquids, others involve in either continuous extractions or batch extractions. Because of environmental concerns, many common liquidliquid processes have been modified to either utilize benign solvents, or move to more frugal processes such as solid phase extraction. The solvent can be a vapor, supercritical fluid or liquid and the sample can be a gas, liquid or solid.
