Design and Fabrication of Evacuated Tube Collector Based Solar Drier

Drying is a method of food preservation that works by removing water from the food crops which inhibits the growth of microorganisms. Solar heating systems to dry food and other crops can improve the quality of product by reducing wastage of seasonal surplus and fossil fuel. This book gives a brief introduction about drying mechanism, solar thermal technology, a short account on survey of various types of driers used for solar drying of agricultural crops. A brief account on evacuated tube collector and its working are discussed. A concise explanation on design and fabrication of indirect forced convection solar drier using Evacuated Tube Collector (ETC), is provided.
