In NEA (Near-critical Expansion Atomization) process, the carbon dioxide is used in this process for the atomization and the crystallization of the product. The product subjected to the process is maintained in the liquid phase in a feed tank at a controlled temperature and subsequently conveyed, at the desired pressure, to the “atomization tower” where there is contact with the carbon dioxide released to atmospheric pressure.
The result is the formation of microscopic droplets (atomization) immediately cooled to temperatures much lower than 0 ° C.
