Used Dryers and Industrial Process Drying Equipment

IPP's inventory of over 600 types of dryers and drying equipment for sale includes used, new/unused and reconditioned dryers for many industrial processes. Try narrowing your search using the 24 sub-group categories first and then use the search box to find what you need.

Guide to Types of Used Dryers & Drying Equipment

Types of Dryers Used in Both Batch & Continuous Processes

Manufacturers/brands in stock may include: Glatt, Niro, Fitzpatrick, Aeromatic, Sahara, Caltherm and others.

  • Fluid Bed Dryers: Found in batch and continuous processes. Product flows across a perforated bed while hot air blows through the bed. Continuous dryers vibrate to move the product while batch dryers use agitators. Popular in pharmaceutical plants. Measured by the Kg/Hr.
  • Oven Dryers: Heated boxes that are either hot air or steam heated. Can operate at atmospheric pressure. Measured by oven's internal dimensions.

Manufacturer / Brands typically in stock:

  • Vickers
  • Struthers Wells
  • Stokes
  • Buss AG Basel Schwein
  • Bethlehem
  • Devine
  • APV/Mitchell
  • Buflovak
  • Zschokke Wortmann AG
  • Spangler and Kaufman
  • Northstar
  • Simpson-Turner
  • Hull
  • Vacuum Dryers: Batch dryers using a vacuum to dry wet products where tumblers, paddle and ribbon agitators or pans move the product. You'll find used vacuum dryers in these categories: double cone, twin shell, rotary vacuum (aka vacuum rotary) and pan dryers.
  • Vacuum Shelf Dryers: vacuum dryers where product is dried on trays sitting on heated shelves. Typically rated for heating only, do not have movable shelves and are measured by the shelves' surface area.
  • Freeze Dryers (Lyophilizers): Low temperature batch dryers, identical to shelf dryers, except they use low temperatures and shelves may be moveable. Common in pharmaceutical production. Measured by the shelves' surface area.

  • Conveyor Dryers: use conveyors to move product through drying chamber or trough. Some are heated or use vacuum conditions. You'll find used conveyor dryers in these sub-group categories:
    • Holoflite, hollow screw, thermal Screw, thermal disc dryers - use troughs, measured by trough's dimensions or number of screws.
    • conveyor belt dryers - product moves through heated chamber on continuous horizontal belt. Measured by chamber diameter and belt length.
    • Porcupine Dryers: Specially designed conveyor type with trough and internal screw conveyor. Some are jacketed and rated for internal pressure.
    • Flash Dryers / pneumatic conveyor dryers: conveys product through heat source and pulverizers before discharge into an air classifier. Measured by dryer's air flow in CFM.
  • Spray Dryers: atomizes liquids into fine spray which dries into fine particles as it floats down through heated chamber, whose diameter is the key measurement. Popular for instant milk, instant tea and pigments.
  • Drum Dryers: heated drum or set of 2 drums where the product is dried on the outside of drum as it rotates toward blade that scrapes it off. Used for milk drying and cereals. Measured by the diameter and length of the drum.
  • Drum Flakers - Similar to drum dryers except use a cooling process to flake the product being dried.
  • Belt Flakers - Belt flakers are conveyor belt dryers that also use cooling where the belt is cooled to dry the product. It hardens and flakes off.
  • Thin Film Dryers: used to convert heat-sensitive liquids, sludges, slurries and pastes into free-flowing solids. Can be horizontal or vertical, some operate under vacuum and are usually measured by the drying surface area.
  • Wyssmont Dryers: have cylindrical housing that contains stack of trays that rotates while hot air blows through the housing. The product is fed at the top and then scraped onto the next tray below continually moving down stack.
  • Continuous Rotary Dryers: Some use Hot Air or direct flame as heat source while others use steam heated tubes. Have large and long cylindrical tubes that dry the product as it tumbles through the rotating tube. Measured by diameter and length of the tube.

Other Dryer Types

  • Air Dryers: find industrial dehumidifiers, dehumidifying dryers, regenerative dessicant dryers, refrigerated dryers, dryers using hot or cool air as well as those used with compressors to remove moisture from compressed air. Measured by CFM. Manufacturers/brands can include Pneumatech, Ingersoll Rand, Hankinson, Arrow, Bartlett-Snow and others.
  • Food Grade Dryers are found in spray dryers, fluid bed dryers and horizontal belt dryers

What is an Industrial Dryer?

An industrial dryer is any processing plant machine that removes moisture to produce a dry, solid product. For dry powders, dryers are typically located near the end of the process line. In chemical or pharmaceutical plants, dryers are typically used after centrifuges or filters have removed most of the moisture in the product.

Because most products dry faster in a vacuum than in atmospheric pressure, you will see dryers with heating jackets and ratings for internal pressure and for vacuum conditions. Other products can be dried economically in a simple , industrially sized hot air oven dryer. Common accessories for dryers include dust collectors and vacuum pump systems.
