SED - Spray Engineering Devices Ltd Limited
Milling System

Maximize Extraction. Minimize Power Consumption.

SED’s Milling Systems, also known as Milling Tandems, are precision-engineered units designed to extract maximum juice from prepared sugarcane with optimal energy efficiency. Featuring Three-Roller Mills with independently driven rollers, VFD-controlled motors, and integrated feeding mechanisms like the Toothed Underfeed Roller (TUFR), these systems ensure uniform load distribution, high juice recovery, and smooth bagasse handling.

Built for continuous operation and energy efficiency, SED Milling Systems combine automation, precision engineering, and robust construction to deliver consistent performance while reducing operational costs.

How It Works

How It Works

Step Icon

Cane Preparation

Harvested cane is fed onto a Cane Carrier, then chopped into smaller pieces by the Chopper and Cutter to improve extraction efficiency.

Step Icon

Cane Distribution

Chopped cane is evenly distributed in the Main Rack and directed toward the first mill for crushing.

Step Icon

Milling Process

The milling tandem consists of a series of Three-Roller Mills:

  • Top Roller : Initiates compression and feeds cane to the lower rollers.
  • Toothed Underfeed Roller (TUFR) : Provides consistent grip and feed for uniform extraction.
  • Feed Roller (Chevron Grooved) : Ensures steady feeding and reduces slippage.
  • Discharge Roller: Smooth bagasse discharge while maintaining optimized juice extraction.

Each roller has an independent VFD-controlled motor, eliminating reliance on energy-intensive main drives.

Step Icon

Sequential Milling

Bagasse is further chopped in intermediate cutters and passed to subsequent mills for enhanced extraction. The number of mills is adapted to plant scale and desired efficiency.

Step Icon

Juice Collection

Extracted juice from each mill is collected and transferred to the Mixed Juice Tank for downstream processing.

Step Icon

Bagasse Handling

Dry fiber (bagasse) is conveyed to storage yards using belt conveyors for reuse or power generation.
