Natural cold storage

Highlight: Now the cold storage using the green technology surely has room for improvement. If it can match the power-driven cold storage in its efficiencies, the country's agro-economy will receive a shot in the arm. The concept of farm management and cultivation too will transform radically

 

An indigenously developed cold storage has proved its efficacy much to the delight of the brains behind it and farmers who were its beneficiaries. It has rightly been called a natural cold storage because it does not require any chemical or electricity to run it. All it requires is natural ingredients with soil and straws making up for its major constituents and parts - walls, shelves and roof included. Its cooling system depends on the process of vaporisation. The organic method used for preservation of vegetables, including the easily perishable items, seasonal fruits and spices gives hopes for farmers all across the country to take the economic benefits the cold storage now offers. The 300-tonne capacity cold storage built at a cost of Tk 1.4 million has yielded good results so far. The first of its kind set up in Rajshahi, this cold storage has made its developers optimistic about the project's bright prospect. 

Sure enough, experiment with the preservation of potato, onion and ginger has been quite successful because those produces were found in good condition after four months. Now another such research project will focus on leafy vegetables and fruits. If such produces can be preserved for two to three months, this will be a bonus for growers of those farm items. For example, if cabbages can be preserved in such cold storages for such a longer duration, farmers will not be forced to dispose of those at throwaway prices. The same applies to other perishable vegetables and fruits. Farmers will feel encouraged to produce more such items if only they know they can keep them in a cold storage that is not only cheaper but also environmentally friendly. In a country where continuous availability of electricity is uncertain, this type of cold storage has its extra merit. Instances are many in which potato and onions stored in electricity-run cold storages rot simply because of frequent load-shedding and at times for long duration. 

Now the cold storage using the green technology surely has room for improvement. If it can match the power-driven cold storage in its efficiencies, the country's agro-economy will receive a shot in the arm. The concept of farm management and cultivation too will transform radically. Both farmers and consumers of their produces will benefit -farmers by maintaining a steady price line and consumers getting the supply beyond the harvesting period. Stable prices instead of fluctuations depending on crisis in off season or glut in the market during harvesting of produces are likely to be the order of the day.

In the process, the greatest achievement will be the removal of the middlemen who rule the roost now. If farmers can take advantage of easily available facilities of storage and transportation, the middlemen who eat the cream will have no place in the marketing system. This will be an indirect but great achievement for the country's farm sectors, courtesy, of course, of natural cold storage. So there is need for more research and experiment in order to perfect the cooling system of the green cold storage.
