Mathesis are the leading Industrial Dryers Manufacturers. Drying is an operation in which moisture / Solvent is removed thermally from a liquid / solid mixture. Dryers vary in application and function.

Selection Of Drying Equipment

# Initial Selection of Dryer

  • Best Suited to Handle the Wet Material and the Dry Product.
  • Which fits into the Continuity of process as a whole.
  • Which will produce a product of the desired Physical Properties.
  • Factors to consider in the preliminary selection of dryer are below

  • Properties of the material being handled
  • Drying Characteristics of the material
  • Flow of material to and from the Dryer
  • Product qualities
  • Recovery Problems
  • Facility available at site of proposed installation

# Initial Comparison of Dryers

  • Evaluation of Size and Cost should be made to eliminate the uneconomical process

# Drying Tests

  • Drying tests need to be conducted on the selected Dryers. These tests will determine the optimum operation conditions and product characteristics.

What are the different types of industrial dryers?
The most common types of industrial dryers are fluidized bed dryers, rotary dryers, rolling bed dryers, conduction dryers, convection dryers, pharmaceutical dryers, suspension/paste dryers, toroidal bed dryers and dispersion dryers.
What are the types and classification of dryer?
Dryers may be classified as direct dryers, indirect dryers, and radiant dryers. The types of radiant dryers are microwave dryers and infrared dryers. An industrial dryer can either operate in a batch or continuous mode. The types of batch dryers are tray dryers, vacuum dryers, pan dryers, freeze dryers, and bin dryers.
What are the uses of Industrial dryers?
Industrial dryers are used to efficiently process large quantities of bulk materials that need reduced moisture levels. Depending on the amount and the makeup of material needing to be dried, industrial dryers come in many different models constructed specifically for the type and quantity of material to be processed.
How does an industrial dryer work?
The outgoing cooled air pre-cools the hot incoming air, condensing the moisture present into liquid water which is drained out of the system. The pre-cooled air then enters an air-to-refrigerant heat exchanger which cools it using a liquid refrigerant.
