Drum Dryer (also known as a Roller Dryer) is one of the most efficient ways to convert liquid slurries or starch into dry flakes or powder. In the food industry, this is the standard machine used for making potato flakes, instant cereal, or modified starch.

Since your business model is a hybrid of in-house manufacturing and branded sourcing, the Drum Dryer is a high-ticket item where you can showcase your fabrication skills.

1. How it Works

1. Feeding: The liquid slurry or starch paste is applied in a thin film onto the outer surface of a large, rotating metal drum.
2. Internal Heating: The drum is heated from the inside, typically using High-Pressure Steam.
3. Instant Drying: As the drum rotates, the heat evaporates the moisture almost instantly, leaving a thin "sheet" of dried product.
4. The Scraper (Doctor Blade): A precision-ground blade scrapes the dried film off the drum.
5. Flaking: The dried sheet falls into a screw conveyor where it is broken into flakes or sent to a pulverizer for powder.

3. Hybrid Manufacturing Strategy

This machine requires heavy-duty engineering. Here is how you can split the work:

• In-House
• Main Frame: The heavy structural steel or SS 304 support frame.
• Product Collection: The screw conveyor and discharge hopper.
• Hood/Vapor Canopy: The extraction system to remove steam.
• Branded Sourcing (Expert Parts):
• The Drum: is in food graid  stainless steel 304 L
• Rotary Joints: Use brands like Deublin or Johnson for the steam inlet/condensate outlet.
• Bearings: High-temperature SKF or FAG bearings are essential.
• Doctor Blade: Precision hardened-steel blades sourced from specialized industrial knife manufacturers.

4. Key Benefits for Slurry & Starch

• Thermal Efficiency: Since the product is in direct contact with the heated surface, heat loss is minimal.
• Nutrient Retention: The "flash drying" (short contact time) prevents the starch from burning or losing its properties.
• Uniformity: Provides a very consistent flake thickness compared to tray drying.

5. Professional Description for Drum Dryer Machine

"Our Industrial Drum Drying System is designed for the high-efficiency processing of starch and thick slurries. We combine our precision-engineered stainless steel fabrication with premium branded rotary steam joints and VFD drives. This ensures a perfectly uniform dried flake with minimal thermal degradation, providing your facility with a reliable, continuous drying solution."

Important Safety Note:

Since these drums operate under high steam pressure, the drum itself must be Pressure Vessel Certified (like ASME or equivalent Indian standards).
