How the CoolMilk System Works
CoolMilk’s technology blends solar power, smart sensors, and food safety compliance to produce clean, high-quality milk — every time.
Step-by-Step Process
Milk Delivery
Cow owners bring freshly milked product to the RCC.
Incoming Temperature Check
Temperature is logged before chilling.
Rapid Chilling
Milk is cooled to below 4°C using solar-powered chillers.
Outgoing Temperature Validation
Post-chill data ensures food safety compliance.
Safe Storage
Insulated tanks preserve milk; IoT alerts trigger if temps exceed 6°C.
Smart Surveillance
Cameras and sensors provide full operational transparency.
Milk Quality Assurance
Automated tracking ensures consistent standards.
Veterinary Oversight
Regular health checks maintain herd wellbeing.
Farmer Development
A 1-year education programme covers animal welfare, hygiene, business management, and cold chain operations.
This end-to-end process is part of a patented innovation — securing CoolMilk’s leadership in rural dairy modernization.
