Spray cooler working principle

Process parameters need to be highly accurate in case of spray coolers. In spray cooling, the material to be cooled is passed from a chamber through which low-temperature air is also passing. The heat transfer between the hot particles and cool air results in the formation of fine powder. hen, the material passes through the conveying duct of the powder dryer machine. Here, the powdered particles are cooled and hardened. The air and powder is then separated in the cyclone separator, and powder is discharged through the rotary valve. Meanwhile, the air gets chilled in the heat exchanger and is again supplied into the cooling chamber. Not only does this help optimize the energy consumption, but also minimizes the load on dehumidification units when the spray cooler is operating in a humid atmosphere.

When melted material first comes into contact with cold air, it begins releasing heat. Then the material begins to congeal at constant temperature and then further cool into stable solid particles. However, not all materials go through the congealing phase. Some fluids go directly into hard solid state without releasing the solidification heat. Spray cooler manufacturer must consider the properties of the melted material to be cooled and the behaviour of its particles in the cooling chamber in determining the design of the cooler.

Spray cooling is used to convert melted feed stocks into particulates that still retain free-flowing properties. The design of a spray cooler is determined by desired particle size and degree of crystallization to be achieved post-cooling for the product. These very factors also dictate whether the cooling should take place in one or two stages.
