A hair dryer (the handheld type also referred to as a blow dryer) is an electromechanical device that blows ambient air in hot or warm settings for styling or drying hair. [ 1 ] [ 2 ] Hair dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand.
A round diffuser in an HVAC system. Diffusers are very common in heating, ventilating, and air-conditioning systems. [3] Diffusers are used in both all-air and air-water HVAC systems, as part of room air distribution subsystems, and serve several purposes: To deliver both conditioning and ventilating air
Heat pump dryers use about 1 kW⋅h of energy to dry an average load instead of 2 kW⋅h for a condenser dryer, or from 3 to 9 kW⋅h, for a conventional electric dryer. [4] [5] [3] Domestic heat pump dryers are designed to work in typical ambient temperatures from 5 to 30 °C (41 to 86 °F). Below 5 °C (41 °F), drying times significantly ...
A vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food and many other products. Walter Zwoyer, the inventor of the technology, patented his idea for the VFFS machine in 1936 while working with the Henry Heide Candy Company . [ 1 ]
3 °C (38 °F) is the realistic lower limit for a refrigerated dryer because a lower temperature runs the risk of freezing the separated water. They are typically specified as primary dryers and generally produce air quality that is appropriate for approximately 95% of all compressed air applications.
Vacuum dryer is the equipment with the help of which vacuum drying is carried out. Vacuum dryers are sometimes made up of cast iron, but most are made of stainless steel, so that they can bear the high vacuum pressure without any kind of deformation. The oven is divided into hollow trays which increases the surface area for heat conduction. The ...
[3] Fine bubble diffusers have largely replaced coarse bubble diffusers and mechanical aerators in most of the developed world and in much of the developing world. The exception would be in secondary treatment phases, such as activated sludge processing tanks, where 85 to 90 percent of any remaining solid materials (floating on the surface) are ...
