Making or shaping ice in great numbers and sizes is the job of an ice production plant. The method used to create ice is quite similar to that used in a typical household refrigerator. The ice-making process is the only difference.
Within the freezer section, water in a tray freezes when it comes into contact with extremely low temperatures; nevertheless, ice is made or frozen at separate circuits in an ice plant, a sizable industrial facility. A cycle for vapor compression refrigeration is used in one circuit to create the cold, while secondary refrigerants are used in another circuit to convey the cold to the water cans.
Principal refrigerant is responsible for transferring heat from the brine to the major circuit. While traveling across the circuit, this ammonia changes phases. The backup cooling agent is responsible for creating ice by removing the water’s heat. CaCl2 or NaCl can be used to make brine. Here we are going to discuss the ice manufacturing plant and its working.
Operations Of Ice Manufacturing Plant
- For the evaporation of ammonia that was removed from the throttle valve, the latent heat from the brine is used.
- Water can easily go toward freezing for the turning into ice when the brine becomes cooled that is circulating in the brine circuit.
- This chilled brine continues to take in the heat from the water and turns it into ice.
- In the form of vapor from the condenser ammonia is released that has been compressed to high pressure and temperature.
- Water cycled in a cooling water circuit with a built-in cooling tower condenses ammonia in a condenser.
- Ammonia is condensed with water from the natural cooling tower using the condenser.
Assembly Of Ice Manufacturing Plant
1- Compressor
For the function of increasing the pressure and the temperature of ammonia vapors that emerge from the evaporator, this compressor is involved. As the compressors pressure increases, the boiling point of ammonia rises. This ammonia with a high boiling point is now prepared to release the heat by condensation at the condenser.
2-Condenser
It transforms high-pressure, high-temperature ammonia into ammonia at such conditions. Here, chilled water from the third circuit interacts with the hot, high-pressure ammonia to provide the temperature necessary for condensation. After cooling at the natural cooling tower, the heated water is sent back into the circuit.
3-Acceptor/ Collector
Ammonia gas from the condenser, in liquid form, is collected using it.
4- Throttle Valve
Ammonia that is released from the receiver is expanded to low pressure.
5-Evaporators
By removing heat from the brine which cools, it evaporates ammonia gas released via the throttle valve. This brine solution is then returned to a water tank containing water-filled ice cans, where the heat of the water is absorbed to cause the cans to freeze, and generate ice.
Conclusion
As we have discussed above, the large household refrigerator freezer is an ice manufacturing plant. The process of making ice uses a brine solution to absorb heat from the water which then turns the water into ice. This process is similar to that of a residential refrigerator.
