Answer:
For the purpose of making storage, the land between two walls should be
filled with sand. The wall and the roof of the chamber should be soaked. In this
way, we can keep the expected temperature and humidity. It is better to have a
permanent water source for wetting. Then the fruits and vegetables in the plastic
crates can be kept in the chamber. The crate should be covered with a thin
plastic. This technique of storage is called storage done in the zero temperature
technique. It is also called Zero Energy Cold Storage System.
It has been found that the fruits stored by the zero temperature technique
are comparatively better than the fruits stored in the refrigerators. This technique
stores fruits and vegetables without any external energy.
For storing the fruits and vegetables, such zero temperature technique
storages are constructed in Kaski, Palpa, Pyuthan, Sindhuli, Kavrepalanchowk
and Jumla districts. Such storages are constructed by using the locally available
materials like brick, stone, bamboo, straw, etc.
The farmers farming in small scale also can store their production in this
method. They can supply their production to the market when they get good
price and earn profit.
