We are proud to partner with Indian Space Research Organisation (ISRO) for dehumidification solutions in the mission-critical areas during assembly of Chandrayaan 2 spacecraft and launch vehicles.
Food losses occur mainly at every stage of food value chain. Majorly, the problem begins with seed, as healthy seeds are essential for healthy plantation. Thus, preservation of seeds are vital. One of the step in seed preservation is to store and dry seeds at recommended environmental conditions. This could help to reduce the amount of food loss. In this newsletter, we are sharing the modern techniques to ensure proper seed drying and storage to reduce food loss.
*In the world, every year approximately
*Global quantitative food losses per year are appox. 30% for cereals, 40-50% for root crops, fruits and vegetables, 20% for oil seeds, 35% for meat dairy & fish
*Key findings on food loss as described by Food and Organization of the United Nation (FAO).
Seed plays a pivotal role for human existence as it is an essential element of the food value chain. Thus, Seed Banks are developed, where seeds are preserved for sustainable future.
However, at seed bank the change in environmental conditions adversely affects the seed quality and its life. Seeds at seed bank should be stored in cool and dry conditions to survive longer because seeds stored at wet, warm environment survives for lesser duration.
At seed banks, the relative humidity and temperature plays a crucial role in seed life. A small change in relative humidity leading to increased moisture content of seed, which has a large effect on the storage life of the seed, especially, on the vegetable and fruit seeds such as tomato, grape, mushrooms, pepper etc.
If the seed drying and storage conditions does not match with required level, the seed cannot survive for long due to fungi and mould attack. Also, it may loose the overall quality like discolouration and loss of viability etc. Hence, seeds should be dried and stored in controlled environment that make them survive for longer duration. Usually, the vegetable and fruit seeds are dried using a seed/tray dryer to maximize the seed life and profitability.
It controls the air around the seeds so they cannot assimilate unwanted moisture that can reduce fungus growth and increase seed shelf life. The dehumidifier ensures protection of the seeds at any temperature without losing seed viability or germination potential.
Bry-Air Tray Dryer consists of a chamber with shallow trays to load the seed and a desiccant dehumidifier, which continuously feeds dry air to the chamber. This unique air distribution pattern optimizes drying capacity and time. It usually reduces the moisture content down to 5-7% from maximum 12%-15%.

We all acknowledge the world is becoming smaller due to the advances in technology and transport. Now, we can travel miles, cross the natural barriers like long rivers, mountains etc. in few minutes.
The travel time has reduced drastically. Thanks to the new roads and bridges constructed to reduce distance barriers.
These modern day bridges are made with a superstructure consisting of closed box sections backing the bridge deck.
The composite steel box girder bridges are commonly used. They generally constitute one or more U-girders attached to a concrete deck through shear connectors.
Since, the bridge girders which are located at industrial areas and water bodies are vulnerable as they are exposed to moisture and atmospheric pollutants like sulphur dioxide and nitrogen oxides. The exposure dictates the corrosion intensity and the challenges on the bridge deck.
The girders, on which the tracks lay, need to be protected against this atmospheric corrosion.
The traditional method of anti-corrosion paint is expensive and demands heavy maintenance.
Yet, it is found to be not effective in the long run to prevent the corrosion.
Since, iron is a major element in the bridge, and when it is exposed to the atmosphere, it will oxidise.
2Fe ->2Fe2+ + 4e–
O2 + 2H2O + 4e- = 4OH–
The hydrolysis of dissolving iron ions is further described by
Fe2+ + 2H2O = Fe (OH)2 + 2H+
In the presence of oxygen ferrous hydroxide will form “haematite” (Fe2O3.3H2O) which is commonly known as rust.
When the moisture level is reduced to < 40%, the corrosion rate in bridge griders will drop significantly. Dry air with < 40% RH level can be supplied through installing Bry-Air Dehumidifier.
Bry-Air Dehumidifier demands minimal maintenance and saves much time compared to personnel applying corrosion protection paint.
