Vacuum drying is a batch operation performed in an air-tight vessel. Using vacuum pumps, the pressure and humidity within the chamber are reduced.
By lowering the atmospheric pressure within the chamber, the materials inside dry more quickly through contact with the indirectly heated walls.
Vacuum drying is generally used for the drying of substances that are hygroscopic and heat-sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure below the vapour pressure of the water, causing it to boil.the pharmaceutical industry vacuum dryer is known by a standard name known as vacuum oven.
Vacuum dryers are generally created from cast iron, however most currently are made from stainless steel, so they will bear the high vacuum pressure without any kind of deformation .
Vacuum drying is the mass transfer operation in which the moisture present in a substance, usually a wet solid, is removed by means of creating a vacuum.
In chemical processing industries like food processing, pharmacology, agriculture, and textiles, drying is an essential unit operation to remove moisture.
Vacuum drying is generally used for the drying of substances that are hygroscopic and heat-sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure below the vapour pressure of the water, causing it to boil. With the help of vacuum pumps, the pressure is reduced around the substance to be dried.
Global vacuum dryer machine market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Maguries new ULTRA 2200 series vacuum dryer is designed to meet the higher throughput requirements of central drying, sheet extrusion, preform, and fiber markets and offers much faster drying than conventional methods while using significantly less energy.
While the principal phases of the vacuum drying process remain the same as those of Maguire’s other models, the ULTRA-2200 utilizes a pair of identical multi-function chambers that alternate in sequence to provide an uninterrupted flow of dry material.
Each chamber can self-load, heat, vacuum, and dispense. This design allows for a compact arrangement with a relatively low ceiling height requirement. ULTRA offers fast, low-cost vacuum drying with intuitive, trouble-free operationMaguire’s first vacuum dryer, the LPD, launched in 2000.
The unique patented design allowed users to dry materials via the application of vacuum and not by dry air as done with desiccant designs.
This fast, modern and efficient process takes a fraction of the time and uses 60% less energy compared to conventional desiccant dryers.
Vacuum drying provides speed and efficiency to dramatically lower energy consumption compared to conventional desiccant dryers.
While each system uses the same amount of energy to heat up the resin, the energy required to dry the material is significantly less — as there is no regeneration process required in vacuum drying.
The result is dramatic savings that not only offer a quick return on investment but the ULTRA models pay for themselves year-after-year for the life of the dryer.
