On the innovative ways of obtaining materials for the processing equipment surface coating in food industry enterprises

The technologies involving the use of different modern nano-sized food additives are relevant in the food industry. All methods for obtaining systems containing nano-sized particles are divided into dispersion and aggregation methods. The dispersion methods as widely known in the food production are well-studied and formalised in terms of equipment. The main disadvantage of mechanical dispersion methods is a possibility of mixing the grinding powder with milling agents. The basic approach to minimization is the production or facing of working areas by wear-resistant materials. The recent studies of fire-proof materials focus on the properties of sintered alumina, which has a high density of particles due to their small size and as a result the increase in mechanical resistance and stability to wear and tear. In this context, this material is favourable to facing the working areas of grinding aggregates, including in the food industry. The nanotechnology analysis proved the technology of selective laser melting of fine powders to be desirable. This technology is multi-functional, and as an innovative decision can be used to get wear-resistant materials when producing the food nanosystems by dispersion. As one of the promising areas for further development is the study on grinding capacity of food systems ensuring the energy-saving production of nano-sized food additives in the context of optimization of their preparation as an element of system approach to the problem solving.
