Dryer Type
           
   Your choices are...         
   Tray / Cabinet / Tunnel Dryer       Tunnel dryers consist of an oven-like enclosure. The material is loaded onto trucks or trays that are stacked on a movable truck.  The trucks are rolled into the tunnel where the material is dried. Air is drawn in through an inlet duct and heated to the required temperature for drying. The heated air is then distributed from side-to-side, or bottom-to-top, in a circular motion. The system can be automated with the trucks on a trolley, being moved in and out continuously. 
   Predryer       Predryers or preheaters provide initial heating or drying of a material before the unit is passed into a larger dryer. Often, radiant heating dryers are used to pre-dry webs before the material is fed into a hot-air dryer. 
   Freeze Dryer       Freeze drying, or lyophilization, is used for the reliable preservation of a wide variety of heat sensitive products and demands the highest standards of reliability and control. 
   Centrifugal Dryer       Centrifugal dryers use a spinning action to mechanically enhance the removal of water, and to increase drying line speed. Typically, centrifugal dryers are used for discrete parts or products, or after washing of these components. 
   Chamber Dryer       Chamber-type dryers consist of a heated chamber that is usually heated to a higher temperature than other dryers. 
   Belt Conveyor Dryer       Conveyor drying uses a perforated belt to transfer feed materials through the dryer. Heated air is either passed under and through, or over and through the belt and product bed before being reheated and re-circulated. Units usually have multiple zones, and may have differing airflow in successive zones. Additionally, each zone may use a different temperature profile and control. Saturated or almost saturated air is exhausted from the dryer via a central exhaust duct. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Heat Source / Transfer:       
   Your choices are...         
   Waste Heat       Waste heat is heat generated or left over from another process. 
   Direct / Convection       Hot air or combusted (or heated) gas) is directly circulated though the material being dried, to convectively heat and evaporate moisture.  
   Combustion       Dryers use heat generated by the combustion of gas, oil, biomass, waste products, or other fuels. The combusted gas may heat the material either directly or indirectly. 
   Electric       Electrical resistance heating 
   Indirect / Contact / Conduction       Walls, tubes, jackets or discs are heated by steam, gas, thermal oil, or hot air. These heated elements transfer their heat to materials that come in contact with them via conduction. Indirect dryers may be useful when contact with combustible gas or hot air is not desirable due to product or process requirements. 
   Radiant / Infrared       Dryers use radiant heat generated by electric or gas-fired infrared heaters. Radiant heat dryers are useful for drying surfaces, flat products or web materials where a clear line of sight can be provided. Straight pass infrared dryers are used to pre-dry web materials before these materials are fed into a conventional, direct, hot dryer. 
   Steam       Steam dryers are indirect dryers that use equilibrium or superheated steam. Typically, the steam is passed through tubes (as in a steam tube dryer) or through a jacket or wall passage (as in pan or rotary drum dryers). 
   Thermal Oil / Fluid       Thermal oil or fluid is heated and used to indirectly transfer heat to a material through a process wall, jackets, discs or other surfaces. 
   RF / Microwave / Dielectric       Radio frequency (RF) generators create an alternating electric field between two electrodes. The material to be heated and dried is conveyed or placed between the electrodes where the alternating energy causes polar molecules in the material to continuously reorient themselves to face opposite poles, much like the way bar magnets behave in an alternating magnetic field. The friction resulting from molecular movement causes the material to rapidly heat throughout its entire mass. Areas in the material with greater moisture content heat up and dry faster. 
   Other       Other unlisted or specialized heat sources.

   Secondary Capability       
   Your choices are...         
   Coating       Dryers allow coating of the material before, during, or after drying. 
   Cooling / Freezing       Materials can be cooled or frozen during or after drying. 
   Moisturizing / Humidifying       Dryers can restore a level of moisture to an over-dried and possibly brittle product. 
   Preheating       Dryers have an integral preheater or preheating capability. For instance, a slurry could be preheated in a tank before introduction to a drum dryer. This technique reduces the heating demands on the drying unit and increasing line speed. 
   Washing / Rinsing       Dryers have an integral washing or rinsing capability. For example, in some pharmaceutical applications, the product may be passed through several rinse and dry cycles to remove liquor.
