About the Cover

A study was conducted to reduce air microflora using clean air system in paneer packaging room of a dairy plant. To evaluate the performance of the developed innovative clean air system and barrier of different section to reduce the infiltration of microbial load in paneer packaging area, the developed Clean Air system was installed in a packaging room of a dairy processing plant. The innovative clean air system consists of 0.3 micron size HEPA filter and multiple reflection of UV irradiation on air borne microorganism in plenum chamber. The system retains the particles/organisms of 0.3 micron size and above by the filter, while mutagenic multiple UV ir-radiations destroys the air borne microorganism in the plenum chamber. The data were recorded for air borne microflora in ambient air, processing section, packaging room i.e. surrounding Clean Air System and on the working table of the clean air system. The data reveals that in ambient condition, processing room, packaging room and on working table of the clean air system, total SPC /15 min. are in the range of 11.4- 62, 4-38, 0.38-1 and 0-1.2 respectively; while, total Yeast & Mold count /15 min. were observed in the range of 8.8- 60.2, 3-34, 0.36-0.76 and 0-1.4 respectively. This shows the step wise reduction of air microflora using clean air system in packaging area of a dairy plant (Ref: Shah BP, Chauhan DK, Shah DR, Shah RR, Chauhan PN.
