This study covers development of batch (holding) pasteurization equipment, in this method every milk particle is heated to at least 63°C and held for at least 30 minutes. The frame analysis was performed using computer aided design simulation software. The frame parts were modelled and assembled before being exported to the frame simulation environment to check the strength and the level of deformation on the frame. Material indices were derived for energy efficient soya milk batch pasteurizer to determine materials that can resist yielding and rusty condition when exposed to various working environment. Based on the material indices derived, CES software 2013 was used to generate graphs showing materials with adequate thermal conductivity, thermal diffusivity, specific heat capacity, density, yield strength and cost property. Considering the performance criterion, stainless steel and low carbon steel was favoured. The maximum von misses stress on the frame is 102.7Mpa, this value is less than the yield strength of the material of 322.5. Analysis of Variance for heat flow (Q) was carried out and the "Pred R-Squared" of 97.55% is in reasonable agreement with the "Adj R-Squared" of 99.46%.
