Used Krauss Maffei MT 1/200 316L Stainless Steel Mixer Vacuum Dryer

MANUFACTURER INFORMATION

Krauss Maffei manufactures industrial process equipment used for mixing, drying, separation and related chemical and pharmaceutical applications. Mixer vacuum dryers of this type use a jacketed vessel and gently moving internal screw to expose product surfaces while operating under vacuum, allowing moisture or solvents to be removed at reduced process temperatures.

PRODUCT DESCRIPTION

Used Krauss Maffei Mixer Vacuum Dryer MT, Model MT 1/200, Serial #7098, National Board #21424. Constructed of 316L stainless steel with polished interior product-contact surfaces. The conical vessel has a total capacity of approximately 49.43 cubic feet with approximately 35.3 cubic feet working volume. Product is gently agitated by an 8" diameter inclined orbiting screw driven by a 10 HP drive, supporting mixing and drying of compatible powders, granules and particles up to approximately 5 mm. The vessel interior and jacket are rated for full vacuum through 150 PSI at 450°F, with a stated maximum actual drying temperature of 302°F. The top head includes an 18" manway with 6" sight glass, 18" flanged connection, 4" sight glass, two 3" flanged connections, two 2" flanged connections, a 6" flanged connection and two 1" threaded jacket fittings. The vessel side includes two 2" flanged body-jacket connections. Bottom discharge is through a 10" flanged outlet equipped with a pneumatically operated flush-mount valve, with two additional 1" threaded fittings for the bottom jacket. Possible applications include vacuum drying, solvent removal, low-temperature drying and gentle mixing of compatible pharmaceutical, chemical, specialty chemical and other powder or granular products.

FAQ

• WHAT IS THE CAPACITY OF THE KRAUSS MAFFEI MT 1/200?
  The vessel has a total capacity of approximately 49.43 cubic feet and a working volume of approximately 35.3 cubic feet.

• WHAT MATERIAL IS THE DRYER CONSTRUCTED FROM?
  The vessel is constructed of 316L stainless steel with a polished interior surface.

• HOW DOES THE MIXING SYSTEM WORK?
  Product is gently moved by an 8" diameter inclined orbiting screw driven by a 10 HP drive. The screw helps circulate material through the vessel during the drying process.

• CAN THIS DRYER OPERATE UNDER FULL VACUUM?
  Yes. Both the vessel interior and jacket are rated for full vacuum through 150 PSI at 450°F.

• WHAT IS THE MAXIMUM DRYING TEMPERATURE?
  The stated maximum actual drying temperature is approximately 302°F.

• WHAT SIZE PARTICLES CAN THE MACHINE HANDLE?
  The dryer is specified for particles up to approximately 5 mm in size.

• WHAT IS THE BOTTOM DISCHARGE SIZE?
  The vessel has a 10" flanged bottom discharge.

• DOES THE BOTTOM DISCHARGE HAVE AN AUTOMATIC VALVE?
  The bottom outlet is equipped with a pneumatically operated flush-mount valve.

• WHY USE A VACUUM MIXER DRYER?
  Vacuum drying lowers the boiling point of moisture or compatible solvents, allowing drying at reduced temperatures. The internal screw continuously moves product to improve heat transfer and expose fresh product surfaces during processing.

• IS THIS TYPE OF DRYER SUITABLE FOR HEAT-SENSITIVE PRODUCTS?
  Vacuum dryers are often used for products that benefit from reduced-temperature drying. Final suitability depends on the product, solvent system, required residual moisture and process conditions.

• CAN AARON EQUIPMENT HELP DETERMINE IF THIS DRYER WILL WORK FOR MY PROCESS?
  Yes. Aaron Equipment can help review your product characteristics, batch size, particle size, solvent or moisture load, required vacuum level and drying temperature to determine whether this Krauss Maffei MT 1/200 may be suitable for your application.

• CAN AARON EQUIPMENT ARRANGE SHIPPING?
  Yes. Aaron Equipment can assist with freight, loading and shipping coordination for domestic or international destinations. Contact Aaron Equipment with your delivery location for shipping assistance.
