  • Food products: Fruits, vegetables, grains, pasta, herbs, and spices.

  • Chemical substances: Pigments, dyes, powders, and resins.

  • Biomass: Wood chips, sawdust, and agricultural residues.

  • Pharmaceuticals: Powders, granules, and medicinal herbs.

Wide Applications of Drum Dryer Machine

What Are The Main Components of The Drum Dryer Machine?

All of our dryers are custom designed to meet the unique processing needs of your material. Whether you need low or high inlet temperatures, short or long residence times, countercurrent or cocurrent, our design team can design a drum drier for your application. While a rotary drum dryer machine is custom-designed based on the material to be processed, its construction is standard to some extend and generally customized in terms of size, materials, mechanical components and add-ons.

The shell of rotary dryers can be made from a variety of materials, including carbon steel, stainless steel, inconel, and many other alloys. The shell can also be customized according to the needs of materials and workmanship. A high-quality drum will increase the efficiency of the equipment and extend its life.

A number of combustion chambers are available. Finding a good combustion chamber is very important for the quality of the product as well as the energy expended to get the final product. The gas stream is most commonly heated using gas, coal or oil burners.

This part is also known as feed chute, is where the raw material is fed into the system, usually via a feed screw or chute. The feed chute is designed to be durable and wear resistant to reduce material buildup.

The transmission assembly consists of electric motor, transmission mechanism, reducer, coupling and so on. The motor provides power for the rotation of the drum. There are several drive types here: gears and pinions, chains and sprockets, friction drives, and direct drives.

How Does A Drum Dryer Machine Work?

Internal Structure of Drum Drying Machine
  1. The belt conveyor sends wet materials to the hopper, and enters the drum from the feeding port. The main body of the rotary drum drying equipment is a slightly inclined rotatable cylinder.
  2. After the material enters the cylinder, it directly or upstream contact with the hot air passing through the cylinder, or in effective contact with the heating wall.
  3. After drying, the lower part of the other end discharges the products. During the drying process, the material is dried in the drum. The barrel rotates slowly, moving from the higher end to the lower end under the force of gravity.
  4. The inner wall of barrel is equipped with plates, which can pick up and scatter the materials continuously, which greatly increases thermal contact surface of materials, improves drying speed and accelerates materials forward movement.
  5. After the heat carrier dries the material, the cyclone dust collector collects the entrained dust and then empties.
  • Combined with hot air, these rugged industrial dryers use tumbling action to efficiently dry materials.
  • In most cases, rotary drum dryers directly fire, which means that the hot air is in direct contact with the material.
  • However, some dryers are indirect, that means the dryer heats materials from the outside to avoid direct contact of the material with the hot air.
  • The hot gas flow can flow from the feed end to the discharge end, or from the discharge end to the feed end.
  • The direction of the airflow and the inclination of the drum determines the speed of the material moves through the dryer.

What Are The Characteristics of The Drum Dryer Machine?

  • The drum dryer is the most reasonable equipment for simultaneous evaporation and drying. Besides, you can carry out its operation continuously, so the product quality is stable.
  • The drying time is short. Hence, you shouldn’t keep the material exposing to high temperature for a long time, so that heat-sensitive materials also have good drying effects.
  • Since the drum dryer is a heat transfer drying system, its thermal efficiency is superior to other types of dryers, it is very economical.
  • The drum dryer machine is flexible in operation and suitable for small batch production of multiple pieces. It’s simple to clean and replaces parts easily.

What Is The Operation Process of Drum Dryer Machine?

Rotary Drum Dryer
  • Before operation, the feed door of the rotary dryer should be open, and then you ought to close the feed door and lock it after the successful feeding process.

  • After finishing the previous preparations, push the drying button to start normal drying work.

  • During the drying process of the rotary drum dryer, you should always pay attention to the dried materials so that you can take immediate measures if anything bad happens.

  • If the machine fails, you should stop immediately, and find out the cause of the failure and eliminate in time.
