Project Report for Banana Cold Storage
A banana cold storage keeps green bananas around 12-15°C, not to ripen them, but to delay ripening and lengthen their commercial shelf life from 3-5 days to 3-5 weeks. This controlled storage enables bananas to move from farm to city market without becoming overripe. The NHB subsidy helps to fund this infrastructure. Sharda Associates provides CA-certified banana cold storage project reports. Starting at Rs. 2,999.

What Is a Banana Cold Storage — And How Is It Different from Ripening?
Three distinct banana post-harvest facilities are frequently confused:
Banana cold storage (this page): Stores green, unripe bananas at 12-15°C with 85-90% humidity to slow ripening and lengthen shelf life — keeping bananas in marketable green state for 3-5 weeks rather than the 3-5 day natural ripening window at ambient temperature.
Banana ripening chamber: Using ethylene gas at 100-150 ppm at a temperature of 16-18°C, it actively triggers and accelerates ripening, converting green bananas into retail-ready yellow fruit in 3-7 days.
Multipurpose cold storage: General-purpose refrigerated storage for a variety of agricultural goods (potatoes, onions, apples, and vegetables) that is not specifically intended to meet banana temperature and humidity criteria.
A banana cold storage and ripening chamber are frequently constructed together, with green bananas initially held at 12-15°C and then moved to the ripening chamber in batches as retail demand dictates. This provides the operator complete control over the supply chain: buy green bananas in bulk at low prices, store them, and ripen in regulated batches to ensure consistent retail supply.
Why Banana Needs Dedicated Cold Storage
Banana is a highly perishable climacteric fruit—once it begins to ripen naturally, the process is quick and irreversible. Without Cold Storage:
At ambient temperature (25-35°C, typical Indian summer), a green banana purchased at the mandi will begin to yellow in 2-3 days and be overripe in 5-7 days.
With adequate banana cold storage (12-15°C), green bananas can be stored for 3-5 weeks without ripening, significantly expanding the marketing window.
This shelf life extension is economically transformative:
- Farmers and dealers can harvest and sell in bulk during peak availability (when prices are lowest), and release from storage when demand and prices are higher.
- Retailers and supermarkets can keep a steady banana supply regardless of daily mandi availability.
- Exporters can store bananas for international shipment deadlines.
The crucial temperature range: Below 12°C, bananas experience chilling injury, which causes skin blackening, pulp damage, and loss of quality. Ripening begins at temperatures over 16°C. The temperature window of 12-15°C must be precisely maintained.
Technical Specifications for Banana Cold Storage
Temperature: 12-15°C (must not drop below 12°C — chilling injury risk). Relative humidity: 85-90% (low humidity causes weight loss and skin browning). Air circulation: uniform temperature and humidity distribution throughout the storage area. Ethylene management: Bananas produce ethylene even in cold storage; ventilation to remove ethylene avoids premature ripening beginning. Chamber design: PUF (polyurethane foam) insulated panels—the same technology as general cold storage, but sized and controlled for banana-specific conditions.
Capacity is often indicated in metric tons (MT) of bananas that can be stored at once. The standard capacity range for MSME units is 50-300 MT.
Cooling system: Direct expansion refrigeration with humidity control; refrigerant possibilities include R-22 (phased out), R-404A, and more eco-friendly refrigerants (R-448A, R-449A).
Combined Banana Infrastructure — Storage + Ripening
The most commercially complete and bankable banana post-harvest operation combines:
- Banana cold storage (12-15°C): To keep green bananas for 3-5 weeks.
- Banana Ripening Chamber (16-18°C plus ethylene): For controlled ripening of batches as demand requires.
Together, these two facilities provide an operator with complete supply chain control: buy green bananas in large quantities when market prices are good, store them in cold storage, and release them to the ripening chamber in batches according to market demand.
The combined operation greatly boosts revenue possibilities when compared to individual plants alone.
- Cold storage: Revenue from storage service fees (per crate per day/week) or working capital savings from purchasing in bulk at reduced costs
- Ripening: Profit from ripening service fee (per crate) or margin on ripened banana trading
The NHB subsidy covers both components; cold storage and ripening facilities are both eligible for post-harvest infrastructure support.
NHB + AIF Scheme Support
NHB (National Horticulture Board): 35% backend capital subsidy (55% in NE/hilly states) on qualified banana cold storage project costs, payable after construction and NHB inspection. Non-repayable.
AIF (Agriculture Infrastructure Fund): 3% interest subsidy for 7 years on loans up to Rs.2 crore with CGTMSE collateral-free guarantee — applies to banana cold storage as an eligible agri-infrastructure asset.
NABARD refinancing is available for cold chain infrastructure in agricultural areas, allowing banks to lend for approved cold storage projects while lowering borrowers’ effective interest rates.
NHB and AIF can be used concurrently for the same project; NHB covers the subsidy component, while AIF covers the loan interest subvention.
Revenue Model
Per-crate storage cost (service model): Banana dealers and wholesale merchants pay Rs.2-8/crate/day, depending on facility quality and market. 500 crates held for 20 days at Rs.5/crate/day is Rs.50,000 every batch.
Own stock (buy-hold-sell): Purchasing green bananas at farm/mandi prices, storing in cold storage, and selling when prices rise – the difference between purchase and sale prices is revenue. Higher potential yield, but increases inventory risk.
Combined with a ripening chamber: A service fee for both storage and ripening is charged per crate, which covers both cold holding and ripening. More comprehensive service and higher per-crate value.
Revenue calculation (200 MT cold storage, 70% average utilisation): 200 MT x 70% = 140 MT stored 140,000 kg/13 kg each crate = ~10,770 crates 10,770 crates x Rs.4/day x 30 days = Rs.1.29 lakh/month.
Project Cost For Banana Cold Storage
Capacity | Capital Cost (Rs.) |
Small (50-100 MT) | Rs.18-35 lakh |
Medium (100-200 MT) | Rs.35-70 lakh |
Large (200-500 MT) | Rs.70 lakh-1.50 crore |
Add ripening chamber: Rs.12-25 lakh additional for a 2-4 cell ripening unit alongside the cold storage.

Frequently Asked Questions
Banana cold storage keeps green bananas around 12-15°C to slow ripening and extend shelf life to 3-5 weeks. A ripening chamber triggers ripening by employing ethylene gas at 100-150 ppm and 16-18°C to transform green bananas into retail-ready yellow in 3-7 days. Both are frequently implemented together to provide total banana supply chain control.
The temperature is 12-15°C, and the relative humidity is 85-90%. Bananas suffer chilling injury when temperatures fall below 12°C, resulting in skin blackening and irreversibly damaged pulp. Natural ripening begins at temperatures above 16°C. The 12-15°C temperature range must be maintained precisely throughout the storage duration.
The National Horticulture Board (NHB) gives a 35% backend capital subsidy (55% in NE/hilly states) on eligible banana cold storage project costs, which are released following construction and NHB inspection. A non-repayable donation. Can be bundled with AIF's 3% interest subsidy for 7 years on loans up to Rs.2 crore.
Green bananas stored at 12-15°C with correct humidity and ethylene management can be kept for 3-5 weeks without ripening, as opposed to 3-5 days at ambient Indian summer temperatures. This increased shelf life is the primary economic benefit of banana cold storage.
Service model: merchants pay a per-crate storage cost (Rs. 2-8/crate/day). Own stock: buy green bananas, hold them, and sell them when prices rise. Combined with ripening: per-crate service cost that includes both cold storage and ripening. A 200 MT facility at 70% utilization and charging Rs.4/crate/day yields roughly Rs.1.29 lakh per month in storage costs alone.
Together, they provide comprehensive supply chain control: acquire green bananas in bulk at low prices, hold them in cold storage for 3-5 weeks, and then ripen them in regulated batches as retail demand dictates. This eliminates reliance on daily mandi supply and allows for pricing benefits from bulk purchasing. The NHB subsidy applies to both components.
