How to Dry Bamboo Powder Using a Rotary Dryer

A rotary dryer is an industrial drying machine that removes moisture from a material. It comprises a cylindrical drum that revolves on its axis, a feeder, a material collector system, and a ducting/ventilation system.

This industrial drying system transfers the heat to the material inside the drum. The hot air dries the material 360° with rotation.

Generally, these machines are suitable for drying materials that need consistent and regulated drying processes.

Step-by-step Procedure For Bamboo Powder Drying Using a Rotary Dryer


Preparation for the Bamboo Powder

Crush and grind bamboo stems. You can use a drum chipper and a hammer mill for this process. Make a fine powder out of them. The powder must be free from all possible contaminants and impurities.

Do the Settings of the Dryer

Ensure you take all the primary security precautions in place. Adjust the drying setting as per the requirement.

Make sure you know the right temperature the powder needs to be dried. It will depend on the water content in the powder, how finely the powder is grounded, and environmental conditions.

Along with the drying temperature, set the rotation speed of the dryer.

Add the Powder into the Feeder

Put the bamboo powder in the feeder and let it enter the dryer drum. Like every machine, this industrial rotary dryer has a limit. Don’t overload the machine. Follow the manufacturer’s recommendation for the same. There must be space in the dryer for airflow.

Process for Drying

Run the machine. It will start revolving at the set speed. The machine’s lifting plate will overturn the powder inside and expose it to hot air. Gradually, the heat exchange between the powder and hot air will start.

A high-temperature furnace gas will be discharged into the dryer to heat the powder at a set temperature.

The heat source of the machine can be coal, gas, oil, etc. It depends on the machine type you use.

From the front, the heat moves toward the end of the machine. It will evaporate moisture thoroughly from the bamboo powder.

Dryness Checking

Once the drying process is over, take the test for dryness. Let the powder cool to room temperature. Next, take a small sample and check its moisture content. The well-dried powder must feel brittle and crisp on your finger. Check if there is any clumping or moisture.


Once the bamboo powder is dry, store it in airtight containers or bags.

Advantages of Using Rotary Dryer For Bamboo Powder Drying


High Production Capability

In industries like cosmetics, pharmaceuticals, textiles, etc, the bamboo powder is required in abundance. Therefore, they need a dryer that can dry large quantities of powder.

A rotary dryer is a high-capacity dryer that dries a large volume of bamboo in a short time.

Consistent Drying

A rotary dryer dries bamboo powder uniformly. The revolving drum of a rotary dryer distributes the heat consistently. As a result, the bamboo powder becomes dry all the way.


Advanced rotary dryers are quite user-friendly. They come with various features making the overall process straightforward. Some new machines feature an automatic lubrication system.

It means operators can work continuously without giving the machine a pause. You also get a cooling and dust control system with some dryers.

Rotary dryer machines feature easy-to-use control systems. With a little bit of training, operators can operate the machine.

Flexible Drying Process

A rotary dryer is a versatile machine that lets you dry bamboo powder with different moisture content and molecule sizes. An operator can set the airflow, heat temperature, and drying duration as per the requirements.

Time-Saving/Fast Drying

Since a rotary dryer is a commercial machine, it can dry material at a large capacity. Moreover, compared to other methods, the machine dries powder in less time. Therefore, it saves time and supports overall quick production.
