Abstract

Substantial amounts of fresh agricultural food products are lost after harvest, during handling, storage, processing, and transport. Drying is a method by which food is kept from spoilage after harvest. In the current study, a simple mathematical modelling is developed for eggplant drying to reduce the physical experimentation. The governing differential equation is converted into an algebraic equation using the finite difference implicit technique. A finite difference equation is developed for each node to determine the water content, and all of the nodal equations are solved simultaneously. Eggplant slices are dried with the aid of a heat pump dryer (HPD) in a closed-loop mode in the current study. The influence of drying air temperatures (30–60 °C), relative humidities (
