Section 5: Agricultural Processing Engineering

Agricultural Engineering deals with the design of farm machinery, the location and planning of farm structures, farm drainage, soil management and erosion control, water supply and irrigation, rural electrification, and the processing of farm products. There are four topics in agricultural engineering mentioned below. 

TopicsSub Topics
DryingPsychrometry – properties of air-vapors mixture; concentration and drying of liquid foods – evaporators, tray, drum and spray dryers; hydrothermal treatment; drying and milling of cereals, pulses and oilseeds.
