processing journey

Follow the care that goes into every grain.

Paddy fields ready for careful harvesting01

IT STARTS WITH THE LAND

Good rice begins
with good paddy

After harvesting, carefully selected paddy is transported to our modern rice mills for processing. From the first selection, quality and consistency guide the journey.

A CLEAN BEGINNING

Cleaned with care
Dried with purpose

The paddy is cleaned to separate unwanted material, then dried before the next stage. Our technical team monitors the equipment and processing conditions throughout.

REVEALING THE GRAIN

A gentle process
A grain protected

The outer husk is carefully removed, turning paddy into brown rice. Controlled operations protect the grain's character while helping minimise broken kernels.

careful milling

Undersized grains are separated from whole grains. Carefully controlled milling, grading and polishing preserve the natural characteristics, texture and flavour of the rice.

Consistent quality. Less wastage.

THE SCIENCE BEHIND THE GOODNESS

Rice milling
Handled with care

Understanding how rice is processed begins with the milling stage. The outer husk is carefully removed while preserving the grain's nutritional value and quality as much as possible.

Hull
20%
Bran layers
11%
Starchy endosperm
69%

The paddy first passes through an indent cylinder, where undersized grains are separated from whole grains. Controlled milling removes the husk and bran layers while minimising broken kernels. Whole grains continue for grading, polishing and quality inspection before packaging.

By-products such as husk, bran and broken rice are utilised efficiently in secondary applications. Our advanced process maximises yield while preserving the natural characteristics, texture and flavour of every grain.

A KERALA FAVOURITE, CAREFULLY PREPARED

Parboiled rice
processing

Approximately 50% of our total production consists of parboiled rice, one of Kerala's most preferred rice varieties.

Three essential stages improve grain strength, enhance nutritional retention and give the rice its distinctive texture and cooking characteristics.

01Soaking

The paddy is soaked before steaming. Water and processing conditions are carefully managed for consistency.

02Steaming

Steaming is part of the controlled parboiling process, helping improve grain strength and nutritional retention before milling.

03Drying

The steamed paddy is dried before milling. Each stage is monitored for product consistency and responsible water management.

GOOD FOR THE GRAIN. CONSIDERATE TO THE EARTH.

Responsibility
comes naturally

Thoughtful systems. Less waste.
A little more care for tomorrow.

01

Effluent
treatment plant

Wastewater generated from soaking during parboiled rice processing contains organic matter that requires specialised treatment before discharge.

Our plant, developed by Galaxy Environ ETP using technology licensed from CSIR-NIIST, applies biological anaerobic treatment followed by chemical treatment to meet environmental discharge standards and significantly reduce water pollution.

02

Water
treatment plant

Our advanced Water Treatment Plant purifies and recycles water used throughout the facility, reducing freshwater consumption while ensuring compliance with environmental regulations.

Recycled water is safely reintroduced into approved production processes, conserving natural resources without compromising quality.

03

Biogas
plant

Organic waste generated during rice milling is converted into renewable energy through our Biogas Plant.

Transforming organic matter into biogas reduces waste, lowers carbon emissions and generates clean energy to support our manufacturing operations.

04

Rainwater
harvesting

Our rainwater harvesting system captures and stores rainwater from facility rooftops, reducing dependence on external water sources while helping replenish groundwater reserves.

This initiative supports long-term water conservation and our commitment to environmentally responsible manufacturing.

CARE YOU CAN COUNT ON

Certified standards
Trust, well earned

Our commitment to quality extends beyond production through internationally recognised certifications and industry-leading manufacturing practices.
