Drying ovens are also used to reclaim metals from contaminated metallic composites. This oven is designed to heat clean different types of industrial materials. Once they are cleaned, they can be reused or recycled. These industrial heating ovens are completely automated and performs the drying process quickly and efficiently.

Features

•  It provides uniform heat with a low, surrounding air temperature in the oven.
•  The drying process is performed within a rotating, stainless steel, low-intensity, infrared emitting retort, which is heated externally.
•  The retort’s rotation allows the materials to tumble and amalgamate.
•  The speed of the retort rotation helps control the oven’s temperature.
•  Controlled temperatures allow for
  •  De-oiling of contaminated materials
  •  Drying for reuse or recycling.
•  Drying oven and accessories are modular in design, enabling low installation costs.
•  Modular accessories include input feeder and output feeder devices
•  It provides a fast method for heat cleaning the following materials:
  •  Chips
  •  Aluminum
  •  Coated parts
  •  Stainless steel
  •  Heat clean or dry brass
•  The oven is designed to remove different types of contaminants, including:
  •  Oil
  •  Paint
  •  Epoxy
  •  Varnish
  •  Lacquer
  •  Moisture
  •  Urethane
  •  Lubricants
  •  Powder coating
  •  Plastic and rubber from ferrous and non-ferrous metal parts
•  The oven’s afterburner chamber provide excess air for complete combustion of all contaminants.
•  Any discharges into the atmosphere are harmless by products of combustion.
•  The oven’s design and operation conform to EPA air emission standards.
•  Construction materials and components include:
  •  Oven enclosure fabricated from heavy gauge steel. The enclosure is coated with rust resistant paint
  •  Self-supporting afterburner exhaust stack
  •  High temperature insulation
  •  Retort consists of heat resistant, stainless steel alloy tubes, with internal flight to transport materials from feeding, to heating, and out-feed zones.
•  Automatic controls allow for a specific set point to be maintained throughout the drying cycle. Time and temperature are automatically controlled and shut off at the end of the process cycle.
•  A variable speed drive knob to adjust retort speed is installed.
•  A digital microprocessor temperature controller maintains the set point temperature by reducing or increasing the heat zone fire.
•  Excess temperature controller with manual reset option shuts off burner heater when the temperature rises above the set point.
•  Processing features include:
  •  Natural, manufactured, or LP gas fuel burners
  •  Zoned temperature control with an automatic cooling system
  •  Variable rotary retort speed to control material flow and retention time
