Introduction:

This project is based on how to store crops and green vegetables for a longer period. Crop and grain types are stored in hot storage. In this way, crops can be protected from fungus. The elementary properties of crops are kept reserved. For this project, we get the necessary heat from sun light. Green vegetable and fruits are stored in cold storage. This makes the vegetable storage safe against fungus and bacteria.

Components required:

1. Solar panel
2. Metal plate
3. Battery
4. Peltier module
5. Heat sink
6. Heat seal
7. Digital Temperature display
8. Cooling fan

Working:

The inner walls of storage chambers are spread with heat resistant materials. The metal black plates are mounted horizontally on the roof top of hot storage. The vertical plates coming from the hot storage are physically connected with horizontal plates. Crop bags are stacked in between vertical plates. At the day time, black metal plates absorb heat from sun light and radiate that heat near crop bags. At night, plates are covered with heatproof covers.

The cooling side of peltier module is faced towards cold storage and hot side towards outer atmosphere. The module is tried to be kept cool by providing necessary heat sink and fan at hot side. The reduced inner temperature of the storage chamber is displayed by digital display. For this process, the required electricity is achieved from solar panel.

Advantages:

1. By using this method we can store our crop and vegetable for a longer duration.
2. The required energy is achieved from solar energy which is a nonconventional and clean source of energy.
