The installation site sits at the edge of a village in Haryana state, surrounded by fields that, two months ago, stood thick with corn. Now the stalks are gone—harvested, baled, and stacked in a field across from the new plant. Soon they’ll feed into the line taking shape under the tin roof.

Market Background

Northern India’s post-harvest burning has become an annual crisis. Satellite images show the smoke plume spreading across the Indo-Gangetic plain, schools closing in Delhi, hospitals reporting respiratory admissions spikes. The government has tried bans, fines, awareness campaigns—none have stopped the burning entirely, because farmers have no economically viable alternative.

Pelletizing offers one. Convert the straw to fuel, and suddenly it has value instead of being a disposal problem. Industrial boilers can burn it. Power plants can co-fire it. Even livestock farmers can use it as bedding or, with careful formulation, as roughage.

Raw Material Characteristics

Corn straw differs from wheat straw in ways that matter for processing. It’s coarser, with thicker stems and higher lignin content. Moisture at harvest runs higher—often 18 percent or more—requiring more drying energy. And the silica content, while lower than rice straw, still accelerates wear on cutting surfaces.

The customer’s feedstock comes from local fields within a 30-kilometer radius. Farmers deliver baled straw by tractor-trolley, stacking it in the yard for inventory. The variation between loads—some rain-washed, some field-dried, some mixed with weeds—means the process must tolerate inconsistency.

Production Line Design

RICHI configured the line for straw’s specific demands:

1. Pre-chopping and feeding system breaks bales and meters material into the process
2. Hammer mill with screens sized for straw’s fibrous structure
3. Rotary dryer sized generously to handle peak moisture loads
4. MZLH series corn stalk pellet machine with increased roller pressure and wear-resistant components
5. Counterflow cooler for pellet stabilization
6. Screening system for fines removal and reprocessing
7. Bagging and palletizing for finished product

The straw dryer is oversized deliberately. In northern India, humidity varies enormously between dry winter days and foggy mornings. Having dryer capacity in reserve allows operators to adjust for ambient conditions without throttling production.

Installation and Timeline

Mechanical assembly finished last week. Now electricians run cables through trays overhead, terminating at motors and sensors. The control panels sit in a air-conditioned room at one end of the building, their screens dark until power comes on.

Commissioning is scheduled for March, after the local electrical utility completes a transformer upgrade. The customer plans to run through the summer, building inventory for the winter heating season when industrial demand peaks.

Benefits and Regional Impact

The plant will consume about 15,000 tons of straw annually at full operation—a small fraction of what the district burns, but a start. If the economics work—if the pellets sell at prices that cover costs and return a margin—more such plants will follow.

For RICHI, the project demonstrates adaptation to local conditions. Straw pelleting equipment must tolerate variability, run on marginal grid power, and be maintainable by local mechanics with limited formal training. This line meets those requirements.
