In India’s dairy belt, millions of litres of milk are collected every day from remote villages. Yet, 5–10% of it never reaches the plant in usable condition – lost to heat, power cuts, and poor cooling.

Traditional Bulk Milk Coolers (BMCs) depend on diesel generators or unreliable grids, both costly and unsustainable.

Prompt Thermal Storage based Bulk Milk Cooler (TSBMC) transforms this reality.

It combines thermal energy storage, solar compatibility, and smart control to provide seamless cooling without diesel or downtime. Whether power is available or not, the system continues to chill milk from 35°C to 4°C in less than two hours, maintaining freshness, preventing bacterial growth, and safeguarding farmer income.

Thermal Storage based Bulk Milk Cooler (TSBMC) isn’t just a machine – it’s a step toward a cleaner, more resilient dairy economy.

Industry Challenges

Rural dairy operations face significant hurdles that compromise milk quality and drive up costs. Frequent power outages, expensive diesel dependency, slow cooling times, high maintenance requirements, and a lack of sustainable alternatives create an inefficient and unreliable cold chain. These challenges directly impact farmer incomes, dairy profitability, and overall milk quality from farm to consumer.

• Unreliable Power Supply: Rural grids experience frequent outages, leading to inconsistent milk cooling and spoilage losses.
• Diesel Dependency: DG sets used to maintain chilling result in 30–40% higher OPEX and increased carbon emissions.
• Slow Cooling Time: Conventional BMCs take 3+ hours to chill milk, causing reduced MBRT and bacterial contamination.
• High Maintenance Costs: Generators and compressors need regular service, leading to downtime and rising operating expenses.
• Lack of Sustainable Options: Few energy-efficient, off-grid models exist, limiting adoption in low-infrastructure areas.

Prompt Solution: Prompt Thermal Storage based Bulk Milk Cooler (TSBMC)

Prompt’s Thermal Storage BMC eliminates the dependency on diesel and grid reliability.

Its patented thermal storage technology, stores cooling energy during power availability and uses it later for milk chilling.

This means:

• Cooling continues even during power cuts.
• Operational cost drops sharply.
• Milk quality is improved due to faster chilling.

With smart automation, low maintenance, and solar readiness, TSBMC offers dairies a greener, more economical way to chill milk.
