Cold Storage Technology offers a cooling solution in a confined environment for preserving various kinds of products across different industries. Industries like – agriculture, processed food, fishery, pharmaceutical, healthcare, etc. are greatly benefited by the cold storage facilities, thus consuming the most prominent share of Cold Storage Technology around the world.
With a market share of 110.2 billion USD and a steeply growing CAGR of 11.6%, cold storage manufacturers are expected to increase significantly in the coming years. Having covered a wide array of services, it’s important to know about Cold Storage Technology and cold storage suppliers in detail.
Construction And Working Of A Cold Storage Plant
At the heart of every cold storage unit are 6 components. These are:
1. Compressor
This is the heart of Cold Storage Technology and the only device that require a constant supply of power. It is used to raise the temperature and pressure of the refrigerant.
2. Condensor
The condenser acts as a heat sink to remove the collected heat from the refrigerant and the circulating water. It helps the refrigerant to change states from gas to liquid at high temperatures and pressure.
3. Receiver
The receiver collects the liquid concentrated refrigerant after it changes its state inside the compressor. On arriving in this component, the liquid expands again and releases the temperature and pressure.
4. Expansion Valve
Using a throttling device, the expansion valve reduces the temperature of the refrigerant which changes the temperature and pressure of the liquid.
5. Evaporator
The evaporator collects the heat from the storage unit and uses it to increase the temperature of the refrigerant. This temperature change creates a vaporizing effect in the liquid refrigerant causing it to release cold gas into the storage unit.
6. Blowers
The blowers help to flow the cold air across the storage unit using the convection process which helps to maintain a constant temperature in the room.
Cold Storage Working Process
To sum up the working process, the refrigerant is passed through the compressor to remove its heat and change it from a gaseous state to a liquid. The compressor applies temperature and pressure on the refrigerant to reduce its boiling point. Due to added pressure, the refrigerant converts from its gaseous state into a liquid state.
Consequently, the refrigerant is transferred to the reservoir and moved slowly to the expansion valve where it loses the temperature in a liquid state.
In the last step, the evaporator collects the heat from the surrounding which again changes the state of the refrigerant from liquid to a gaseous state. This causes the cooling effect which is circulated throughout the freezer using blowers.
