Exploring the Ripening Chamber and Cold Room

Process of Banana ripening?

Banana ripening chambers are engineered to stimulate natures ripening process by temperature control, exposure to uniform & controlled ppm of Ethylene gas, venting of CO2 gas and reducing total ripening process to 4-6 days for  best quality.


Benefits of Ripening Chamber ?

Different banana varieties may have specific ripening requirements and storage preferences. Ripening chambers and cold rooms can be tailored to accommodate these variations, providing customized conditions to optimize the quality and ripening process for each banana cultivar.

Many modern ripening and cold storage rooms are designed with energy-efficient features to reduce overall energy consumption and environmental impact.

They allow you to control the ripening process, giving you more flexibility in choosing when your bananas will ripen.

They ensure uniform ripening of your bananas, providing you with a more consistent product.

They allow you to ripen bananas faster, saving you time and money.


What are the major component of ripening chambers ?

The major components of ripening chambers are:

(a) Puff insulated chambers

(b) Insulated doors

(c) Refrigeration system with higher airflow evaporator

(d) Control panel

(e) Humidifier

(f) Ethylene generators  & CO2 and Ethylene analyzers to monitor levels of gas in the room

(g) Crate for stacking


What are the things to be kept in mind for designing Banana ripening chambers?

Following things to be ensured while designing the commercial ripening room:

(a) The room must be as air tight as possible to prevent ethylene loss

(b) The room must be properly insulated to  be able to control the temperature within a degree or so

(c) The room must have adequate  refrigeration capacity to accurately control pulp temperature

(d) The room must have adequate air circulation

(e) The room may need heating equipment in order to maintain proper room temperature in cold weather.


What is the room temperature required for banana ripening?

Bananas are very sensitive to temperatures. Chilling will occur if the fruit is subject to temperatures below 56 °F (13 °C) for several hours & avoid temperatures  above 65 °F (18 °C). The fruit may be soft and have a short shelf life.


What is the humidity level required for Banana ripening?

For best ripening results, humidity should be 90% to 95% to prevent moisture loss. If  the humidity is too low, install a humidifier; wetting the floor of the room with water may increase the humidity but may cause sanitation issues.


How Much Does a Ripening Room Cost?

In ripening chambers, a source of ethylene gas or ethylene-emitting products is required. The size of the room depends on the quantity of bananas you need to ripen. The cost of setting up a ripening chamber or cold room specifically depends on factors such as size, capacity, technical features, energy efficiency, and customization options.

Initial investment costs and ongoing operational expenses should also be considered when planning the construction of banana ripening chambers and cold storage rooms.


What is the specification for air circulation inside the chambers?

Recommended air flow for exporting of bananas should be 2000 Mtr cube  per hour, per MT of product ripened at 95% Relative Humidity. However, local manufacturers may ripen bananas with air flow between 1000-2500 cmh per ton of product.


What is the materials which is used for ripening ?

Ethylene  gas with suitable detection and dosing equipment to maintain ethylene concentration within required levels depending on product (Range 10 to 200 ppm)


What is the conditions for storing of banana in cold storage?

Storage temperature : 13 to 14 °C

Relative Humidity : 90-95%

Storage life : up to 6 weeks at 14 °C


What are the practices for ripening of banana in ripening chamber?

a) Ripening temperature should be maintained between 14-20 °C

b) Relative humidity should be maintained at 85-90%

c) For quick ripening, happened at higher temperature within 4 days

d) For slow ripening, happened at lower temperature within 8- 10 days

e) Forced air ripening system is recommended for new facilities

11) How much gap provided between stacking during ripening of banana?

Boxes of banana should be stored in stacked rows and provide 100 mm gap between the rows for air ventilation.


How much ethylene gas needed for banana ripening?

For banana Ripening, required ethylene gas value is 100 ppm is needed which is 0.1 cu.ft. of ethylene per 1000 cu.ft. of room. So,the recommended hours for ethylene gas addition in Ripening room is 24-48 hours.


What is the condition for storing of banana in Controlled Atmosphere (CA)?

a) Concentration of o2 lies between 2-5%

b) Concentration of Co2 lies between 2-5%

c) Maintain the humidity of room between 90-95%


Banana Ripening Cold Room



Do Cold Rooms Affect the Nutritional Value of Bananas?

Cold rooms use refrigeration systems to maintain a consistent temperature throughout the storage area, preventing temperature fluctuations that could lead to premature ripening or spoilage.

When properly maintained, cold rooms do not significantly affect the nutritional value of bananas. By preserving the freshness of the fruit, cold rooms help retain essential nutrients, making bananas a healthy and delicious snack choice.


What is the subsidy for ripening chamber?

Several subsidy schemes are available for establishing banana ripening chambers in India, offering financial assistance to entrepreneurs. he National Horticulture Mission (NHM) and State Horticulture Missions often provide credit-linked, back-ended subsidies for setting up ripening chambers.

These subsidies can range from 35% to 50% of the project cost, with higher percentages often offered in hilly and scheduled areas.

The admissible cost for a ripening chamber is typically around ₹1 lakh per metric ton.

For example, a five-chamber ripening unit with a 7 MT capacity per chamber (total 35 MT) could receive a subsidy of 7.50 lakh.

The subsidy is released in installments, with the first after civil structure completion and equipment purchase, and the second after commercial operations begin.


What are the diseases and injuries of banana storage?

Anthracnose, Blackrot, Chilling injury, Fruit spot, and Rhizopusrot.

Bananas, whether green or ripe, are prone to bruising easily. Handling them with care at each stage will reduce bruising and enable you to sell them at a higher price.


Is there any other ripening chamber?

Of course. In addition to banana ripening chambers, there are also mango ripening rooms, avocado ripening chambers, papaya ripening chambers, cheese ripening rooms, tomato ripening rooms, and ethylene ripening chambers.
