Shelf Life is an Engineering Outcome.
Not a Luck of the Cold Chain.

FSSAI and HACCP-ready processing and storage environments i.e., from blast freezing and controlled atmosphere to ambient dispatch i.e., engineered to maintain product quality and eliminate cold chain breaks.

🍎Industry Context

India Loses Significant Food Production to an Inadequate Cold Chain.

Only a fraction of perishable food in India moves through an organised cold chain, compared to 70–80% in developed markets. This gap represents both a significant economic loss and an engineering opportunity. The root cause is not a lack of awareness i.e., it is a lack of correctly engineered first-mile and mid-chain infrastructure.

Modern food & beverage cold chain infrastructure goes far beyond simple refrigerated storage. It requires HACCP-driven process design, FSSAI-compliant hygienic construction, multi-zone temperature management, blast freezing capability for IQF products, ripening chamber automation, and energy-efficient systems that keep operating costs competitive while meeting increasingly stringent food safety regulations.

Multi-Zone Temperature Architecture

Hygienic Design Principles

Every construction detail engineered for cleanability, food safety, and regulatory compliance.

Coved wall-floor junctions i.e., eliminate 90° corners where bacteria accumulate
Stainless steel kick plates (300mm height) at all wall bases
PU-coated floor finishes: anti-microbial, chemical-resistant, non-slip (R11-R13)
Drainage slope: minimum 1.5% gradient toward floor drains
