A.3.b) A drum drier 0.7 m in diameter and 0.85 m long operates at 150 °C and is fitted with a blade to remove food after % of a revolution. It is used to dry a 0.6 mm layer of 20% w/w solution of gelatin, pre-heated to 100 °C, at atmospheric pressure. What is the speed of the drum required to concentrate the product to 80% w/w gelatin? Assume the drying rate is constant. Additional data: Density of gelatin feed: 1200 kg m-³ Overall heat transfer coefficient: 1200 W m² K¹ Latent heat of water evaporation: 2.257 x 10° J kg¹
