Load the Dryer If you did not separate loads by fabric type when washing do it now before placing items in the dryer It's important to dry all lightweight items together and all heavy fabric items together and choose the correct dryer temperature for each This will help prevent shrinking and protect your clothing

Wet granulation involves the massing of a mix of dry primary powder particles using a granulating fluid The fluid contains a solvent which can be removed by drying and should be non-toxic Typical solvents include water ethanol and isopropanol and methylene chloride either alone or in combination The granulation liquid may be used alone or more usually as a solvent

Steam dryers: Steam drying is a special drier design that uses superheated steam produced via a heat-exchanger The drier consists of a pressure vessel in which the water from the product is driven off turned into steam and then used to dry more product This system is used in the sugar industry on a limited scale for drying beet pulp

Osmotic dehydration (OD) is a technique used to reduce water activity (a w) in foods in order to improve nutritional sensorial and functional properties of food It consists of an immersion of the product into a concentrated solution (i e sugar salt sucralose etc ) A driving force for water removal is set up because of a difference in osmotic pressure between the food and its

Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air They can also be indirectly heated to avoid direct contact between the material and processing medium The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum

A system fabricated to expedite raising the temperature of an object in vacuum drying is a high-speed vacuum dryer that uses both heating with warm air circulation and vacuum drying This system uses vacuum drying after raising the temperature of an object to be dried using warm air circulation in an atmosphere environment

Freeze dryers can be informally classified by the type of product chamber: (1) Manifold dryers where the product is typically pre-frozen in flasks (2) Shelf dryers where the product is placed in a tray or directly on a shelf (3) Combination units with both drying options Freeze-dryers can also be grouped by size use: (1) laboratory bench
