THE PARAMETERS ANALYSIS OF ALKALINE AND ACID MEANS EFFECTIVE USING FOR DAIRY INDUSTRY EQUIPMENT

Abstract

The results of the parameters analysis of the alkaline and acid means efficient using for cleaning and disinfecting
dairy industry equipment in one washing cycle Clean-In-Place (CIP) mode are presented. These
solutions were created, protected by Ukrainian patents and suggested for using by the authors. In the previous
studies, the absolute individual washing capacities of both solutions were proven. The optimization of
the alkaline and acidic means using conditions was carried out at minimal temperatures recommended by
the standard. Maximal possible dilution degrees of washing properties were determined. Dairy equipment
washing in the industry according to the standard of Ukraine, as well as the results of researches and recommendations
of Ukrainian and foreign scientists, requires using both solutions in one washing cycle. That
is why, in order to identify the best effect, the optimization of the conditions for their using was carried out.
In the work, the results of experimental studies of the alkaline and acid solutions washing capacity for washing
dairy industry equipment internal surfaces in the СIP mode under different degrees of dilution and minimal
temperatures are presented. The advantages of the developed and suggested means, as well as high effectiveness
of their complex application, are shown. The optimal conditions for conducting high-quality
washing are defined and suggested. The satisfactory washing effect of milk contaminants in the static mode
using alkaline and acid detergents, created by the authors, at 1:9 diluting and maximal permissible temperature
regimes was proved. The results of removing 3-day milk contaminations when the temperature regime of
acid treatment is decreased to t=65°C at 1:9 dilution of both solutions are presented. The effectiveness of
detergents to remove one-day milk film with decreasing the temperature of acid treatment to t=60°C at 1:9
dilution of both solutions is shown. The optimal conditions for the complex application of alkaline and acid
detergents while washing the dairy industry equipment in CIP-mode created by the authors are detected.
High washing effectiveness under these conditions is proven. Since the obtained results create a good prognosis
for satisfactory disinfection effect, in future there is the necessity to determine the effectiveness of removing
microorganisms with the suggested means and optimize the conditions for their using.
