Rotary Drum Dryers for Continuous Bulk Drying
Mecha Engineering Pvt. Ltd. is a Drum Dryer Manufacturer in India, building rotary drum dryers for continuous moisture removal from bulk solids in the agro, food, herbal, chemical, and mineral industries. The dryer uses a rotating cylindrical drum with internal lifting flights that cascade the material through a stream of hot air, so drying is even and the output is consistent.
Based in Saharanpur and supplying across India and to export markets, we build each drum dryer for your material, moisture level, and throughput, with the heating method that suits your product. Every dryer is supported with dryer selection, capacity planning, installation guidance, and after-sales service.
Whether you are drying grains, minerals, chemicals, or agro by-products, the dryer is built for steady, high throughput operation with a low energy cost per kg. Contact Mecha Engineering Pvt. Ltd. for a drum dryer matched to your material and capacity.
Features of Our Drum Dryer
- Even Moisture Removal: Continuous rotation and lifting flights cascade the material through the hot gas, giving uniform drying and consistent final moisture.
- Heavy Duty Drum: A heavy duty cylindrical shell on trunnion rollers handles dense or abrasive bulk materials over long operating cycles.
- Direct or Indirect Heating: Hot gas can contact the material directly, or the drum can be heated indirectly for products that must not touch combustion gas.
- Energy Efficient Airflow: Flight design, insulation, and airflow are set to lower the energy used per kg of dried product.
- Continuous, High Throughput: Built for steady, high volume drying with reliable batch to batch results.
- Easy Maintenance: Simple mechanical design and easy access points reduce downtime and service cost.
How a Rotary Drum Dryer Works
- Feeding: Wet material is fed into the inlet end of the slightly inclined rotating drum.
- Lifting and cascading: Internal flights lift the material as the drum turns, then let it shower down through the hot gas stream, which exposes a large surface area to the heat.
- Heat transfer: Hot air or gas removes moisture by contact, either directly through the drum or indirectly through a heated shell for sensitive products.
- Moisture removal: Evaporated moisture leaves with the exhaust, which is passed through a cyclone or dust collector to recover fine particles.
- Discharge: The dried material moves down the incline to the outlet at the required moisture level.

Frequently Asked Questions About Drum Dryer
What is a drum dryer?
In this case a drum dryer is a rotary drum dryer, a rotating inclined cylinder with internal lifting flights. Wet bulk material cascades through a hot gas stream inside the drum, the moisture evaporates, and dried material is discharged at the outlet.
How does a rotary drum dryer work?
Wet material is fed into the rotating drum. Lifting flights raise the material and let it shower down through hot air, which removes moisture. The dried product moves along the slight incline to the discharge end while moist air leaves through the exhaust.
What materials can it dry?
It dries bulk solids such as grains, agro by-products, spices, chemical powders, salts, sand, minerals, and biomass. The flights and heating are set to suit the material.
What capacity do you offer?
We build drum dryers across a range of throughputs and size the drum to your duty. Share your material and required capacity and we will recommend a configuration.
What heating source is used?
Hot air, gas, oil, or steam can be used, with direct heating for most materials and indirect heating where the product must not contact combustion gas.
What material is the dryer built from?
The drum is built in mild steel or stainless steel depending on the product and the duty.
Do you provide installation and after-sales support?
Yes. We help with dryer selection and capacity planning, and we provide installation guidance, spares, and ongoing service.
Do you supply drum dryers outside India?
Yes. We supply across India and to export markets.
