TL;DR: In this article, low-cost drying technologies suitable for rural farming areas are presented and some of the important considerations with regard to their suitability include low initial capital; easy-to-operate with no complicated electronic/mechanical protocol; effective in promoting better drying kinetics.
Abstract: Low-cost drying technologies suitable for rural farming areas are presented. Some of the important considerations with regard to their suitability include: 1. Low initial capital; 2. easy-to-operate with no complicated electronic/mechanical protocol, and 3. effective in promoting better drying kinetics. The drying technologies that were selected include fluidized bed, spouted bed, infrared, solar, simple convective and desiccant drying. A brief introduction on each drying technology has been presented followed by some technical details on their working operations. Examples of farming crops suitable for the employment of individual drying technology are provided to illustrate their potential application in agricultural product drying.

TL;DR: In this paper, a mechanistic model is presented for predicting the moisture and temperature distribution of biomaterials undergoing stepwise temperature drying, and good conformity of up to 74% was obtained between the simulated results and experimental data from product moisture, temperature and temperature.
Abstract: A mechanistic model is presented for predicting the moisture and temperature distribution of biomaterials undergoing stepwise temperature drying Good conformity of up to 74% was obtained between the simulated results and experimental data from product moisture and temperature The calibrated model was used to conduct a parametric study on the stepwise variation of the air temperature and the impact on the internal temperature distribution and quality kinetics The benefit of employing stepwise temperature profiles includes reversing the direction of heat flow within the product, resulting in appreciable improvement in product quality parameters such as ascorbic acid retention and surface color

TL;DR: In this paper, an optimization procedure for heat pump drying via an air side process parameter, known as contact factor (CF), for single and multi-chamber drying is presented, which allows one to optimize the dryer performance through judicious selection of the drying conditions.
