Infrared drying IR uses the energy from IR radiation to directly heat the bulk material of the polymer granuleflakeThe delivered energy is applied directly to the granule with no other transfer mediumThe applied energy causes internal heating and molecular oscillation and therefore heats the bulk material of the granule and any internal moistureA stream of cooler ambient air surrounds the granule and the internal heat drives the moisture out into the cooler air stream that removes it from the process.

Infraredair dryers come in many configurationsFor one infrared heaters can be used as predryers before hot air dryersThe infrared predryer quickly raises the product temperature starting the evaporative process before the product enters the hot air dryer resulting in faster line speedsThis drying method is effective on textile fabric finishing ranges and paper coating lines figure 4.
IR drying provides significant advantages over conventional hot air HA drying or natural drying methods including high heating intensity and drying ratesOur research team has developed several novel drying technologies including IR drying sequential IR and hot air SIRHAD drying and sequential IR and freeze drying SIRFD etcThe feasibility of IR drying for improving the drying efficiency energy efficiency and product quality on different food materials such as rice walnuts pistachios almonds bananas apples carrots and jujubes etcHave been investigated systematically.
IRenhanced convection combines the best properties of infrared and convection oven systems and produces a highquality coating in significantly less time than is possible using convection methods aloneIn addition IRenhanced convection produces more processfriendly characteristics than are possible with IR alone.
Jul 06 2020nbsp018332Infrared IR radiations are an important source of energy used in the food industry for a wide range of applications such as drying roasting pasteurization blanching peeling and removal of antinutrients from legumes.
Maintenance costs for a gas infrared oven may be less than an electrically powered ovenThe radiant face of a gas burner has an average operating life of four to five years minimumThe gas infrared oven will require some replacement of gas valves flame safeties and safety switches but the amount required on a yearly basis is less than some electric infrared ovens such as those using T3 lamps which require regular maintenance to replace broken or burned out bulbs.
May 01 2003nbsp018332Figure 2For efficient drying with infrared it is best to mount the infrared heaters in an insulated oven enclosure as in this 8.

Nov 01 2001nbsp018332At 1600 o F the gas infrared burner converts about 60 to 65 of its available heat into longwave infrared heat while the remaining 35 to 40 is convective heat that enters the oven work chamber to contribute to the overall heating and drying.
Nov 01 2001nbsp018332Gasfired infrared equipment is well suited for drying and curing webtype substrates such as paper cloth aluminum and steelUsually an electric infrared lamp requires a reflector while a porous screen gas infrared burner does notGas or electric infrared ovens will dry or cure coatings substantially faster than hot air convection ovens.
One limitation of IRcuring technology is its complexityWhereas traditional coating operations require managing relatively few variables during the curing process particularly those involving straight convection ovens IRenhanced convection involves more variablesbut more opportunities for finetuning the cureAs a result it is necessary to have a thorough understanding of the principles of both IR and convection energy transfer.

The gas infrared burners can operate in the oven environment without requiring any cooling air to the burnersCooling is sometimes a requirement for electric infrared heatersWith gas infrared burners the only exhaust air needed is the amount required to remove the products of combustion from the gas infrared burners and any evaporated moisture and solvents.
The infrared tunnel oven is equipped with an internal infrared heat source for drying the products from inside to outside leading to high drying efficiencyInfrared tunnel ovens are generally used for drying silk screen signboard and disc printing ink as well as food processing like biscuit processing and nut processing Power 380V Heating.
The porous radiant face can be made from a number of materialsMost infrared heaters of this type use a ceramic face with many small holes or fine Inconel wire mesh screensAlthough the ceramic material will withstand higher temperatures due to production restraints the minimum hole size in the ceramics is larger than in the Inconel wire mesh screens which have up to 1600 openingsin2.
These systems can be used for drying both hygroscopic and nonhygroscopic materials but are particularly suited to the drying of reprocessed PETPET processing uses crystalline granules but the material becomes amorphous during processing – therefore PET regrind is amorphous and must be recrystallised before it can be processed againHistorically a separate recrystallisation process was used prior to drying and processingIn IR drying processes the PET is raised above Tg and continuously agitated during the process this effectively combines recrystallisation and drying in one pass.
This system uses a horizontal drum containing an internal spiral feed which transports and agitates the material as it is carried along the drum underneath the IR heatersThe final moisture content of the polymer is determined by the power rating of the IR heaters and the residence time in the systemThese can be finely controlled by the rotation rate of the drum and the power applied to the heaters.
