The selection of the most suitable cooling nozzle/atomizer, includes a thorough knowledge of the following parameters:
– The amount of heat to cool down
– The required cooling rate
– The geometry (shape) of the products that must be to cooled down
– The heat transfer capacity of the product to be cooled
When the range of products to cool is limited the choice is simpler, but when the range is wide, either for the shape or for the different raw material quality, it is necessary to subdivide the range according to a variety of criteria and resort to a wider choice of nozzles/atomizers. Therefore, the above-mentioned parameters should be evaluated for each sub-range. A crucial factor in the choice is also the degree of purity of the coolant that can steer the choice towards a model of more clog-resistant nozzle/atomizer.
