Ice slurry Generator – Cooling System using Ice Slurry Media

Dr. Agus S. Pamitran, S.T., M.Eng., developed a cooling innovation that is very useful for traditional Indonesian fishermen. Traditional fishermen use blocks of ice from land to store their fish. Fishing duration depends very much on the existing stock of ice blocks. Inspired by that constraint and trying to help those traditional fishermen, the Department of Mechanical Engineering invented an ice slurry maker made of seawater. That innovation aimed to reduce the fishermen’s dependence on their ice blocks and create the ease of ice-making in the middle of the sea so that the fishing duration would become longer. Since beaches currently contain a lot of pollutants, the fishermen should go further away from the coastline. The ice slurry allows them to obtain a smoother and even cooling medium to cover their fish. It will keep their fish and make them fish without the risk of being damaged, like what they experienced when using ice blocks. They Can adjust The temperature of the ice slurry to be formed based on the salinity of the sea. The higher the saltiness of the fluids is, the lower the included ice slurry temperature will be. Therefore, the cooling media could be regulated in water with low salinity to keep the fish fresh and dedicated to consumers who do not like frozen fish. 

In addition to cooling fish and other products, ice slurry is also used in a cooling system as a secondary refrigerant. For example, in a cooling building using cold storage, ice slurry can be used to reduce the initial investment cost of the cooling system. This research used water-glycol and Sodium Chloride as their cooling agents.
