A Single Drum Dryer is a continuous industrial dryer where material is fed onto the surface of a rotating heated drum. As the drum rotates, heat is transferred to the material, removing moisture efficiently. It is ideal for materials with moderate to high moisture content and ensures consistent drying with minimal handling.
A Double Drum Dryer consists of two heated drums operating in tandem, allowing for higher drying capacity and more uniform heat transfer. This design is especially suited for industries needing large-scale production with consistent quality, handling viscous slurries, pastes, or granular materials efficiently.
GEM Single/ Double Drum Dryers convert molten liquid or pasty feeds into solid dried particles. Two identical drums are installed next to each other and the material is fed from the top into the gap between the drums. A thin layer of molten feed forms on the outside surface of the rotating drums. The Inner Surface of the drums are heated with steam or hot water. This results in heating of the drum and removes the excess moisture from the molten feed which after scraping results in a dried powdery product.
The material dried is collected through a chute or a conveyor. The speed of the drum can be controlled through a VFD. The capacity of the dryer depends on the material of the product, the temperature of the product, the dip level of the drum in the molten feed and by the temperature of the drying medium/drum.
DRUM:
The material of the drum could be Mild Steel, or any grade of Stainless Steel with or without Hard Chrome plating. The surface of the drum is machined and ground. The drums rotate on antifriction self-aligning ball / roller bearing with standard Housing.
SCRAPPER:
The Scrapper Knife scrapes off the solidified material from the surface of the drum. The material of construction of the Scrapper knife is usually Stainless Steel or Phosphor Bronze. They are designed to ensure uniform pressure against the drum over the full length. The pressure of the knife is controlled by an adjustment screw.
HOOD (OPTIONAL):-
To prevent toxic vapours, the dryer/flaker is equipped with a totally enclosed hood with vapour outlets on top.
DRIVE : – Heavy duty drive is designed for smooth, continuous and trouble-free running. V-pulley or variable speed arrangement can also be provided for optimum performance.
Provides effective moisture removal for a wide range of materials.
Continuous rotation and scraping mechanism ensure consistent drying across the material.
Optimized heat transfer from steam or thermal oil reduces fuel and operational costs.
Supports large-scale industrial production with minimal interruptions.
Can process powders, slurries, granules, and heat-sensitive materials.
Ensures continuous tumbling of material for uniform heat transfer and drying.
Can use steam, thermal oil, or direct flame depending on material sensitivity.
Controls residence time and drying intensity for different materials.
Made of stainless steel or carbon steel for durability and corrosion resistance.
Scrapers or rotating mechanisms ensure smooth removal of dried material.
Occupies minimal floor space relative to production capacity.
Unicoco, Indonesia was excited about the Coconut project, but through GEM we made this dream come true. GEM machines: dryers / screw conveyors / bleachers / graders, etc. they are absolutely good and require little maintenance. Also, we get 24×7 support from them in case we get stuck at any time.
GO FOR IT!!!
PT Unicoconut Industries Indonesia, Indonesia
Franklin Baker Company of the Philippines, in its continued effort to be the gold standard in processed coconut products, continues to partner with the best OEM suppliers for our manufacturing line requirements. One of them is GEM Forgings, which has been our trusted supplier of process equipment for our DC (desiccated coconut) dryers. We both value quality and service level in our business dealings.

I have heard about the progress of your drying equipment and our staff was amazed at its performance, which is above average compared to the old dryers we have.
I have advised the plant managers at both plants to contact you about upgrading our existing dryers to meet the specifications of the new one.
Therefore, I would like to congratulate you on the new technology that you have integrated into the drying process equipment.
