“…By establishing mathematical models, the temperature distribution of different shapes (slab, cylindrical, and spherical) was found to be quite different. The spherical shape had the smallest surface area and smallest heat loss, while the plate shape had the largest surface area and therefore the largest heat loss among the samples [ 71 ••]. Such difference was one of the factors affecting the disinfection effect.…”

Purpose of Review In the context of COVID-19 sweeping the world, the development of microbial disinfection methods in gas, liquid, and solid media has received widespread attention from researchers. As a disinfection technology that can adapt to different environmental media, microwave-assisted disinfection has the advantages of strong permeability, no secondary pollution, etc. The purpose of this review is to put forward new development requirements for future microwave disinfection strategies by summarizing current microwave disinfection methods and effects. From the perspective of the interaction mechanism of microwave and microorganisms, this review provides a development direction for more accurate and microscopic disinfection mechanism research. Recent Findings Compared to other traditional environmental disinfection techniques, microwave-assisted disinfection means have the advantages of being more destructive, free of secondary contamination, and thorough. Currently, researchers generally agree that the efficiency of microwave disinfection is the result of a combination of thermal and non-thermal effects. However, the performance of microwave disinfection shows the differences in the face of different environmental media as well as different types of microorganisms. Summary This review highlights the inactivation mechanism of microwave-assisted disinfection techniques used in different scenarios. Suggestions for promoting the efficiency and overcoming the limitations of low energy utilization, complex reactor design, and inaccurate monitoring methods are proposed.

Solar drying is a non-polluting and economic drying process which utilizes solar energy to dry the food materials for better shelf life. We have fabricated a simple, efficient, and economically feasible indirect type solar dryer for food preservation. This article presents the dynamic model of fabricated solar dryer. This model consists of thermal modeling of the drying chamber, solar collector, and solar dried- food sample. The energy balance has been applied to evaluate the temperature at different sections of the solar dryer with respect to drying time. Model equations have been solved in the MATLAB environment. Solar power meter and infrared thermometer used as measuring instruments. This study helps to examine the influence of solar radiation on the collector plate temperature, drying chamber temperature, food sample temperature, and performance parameters such as thermal efficiency with respect to drying time. Model data has been found in good agreement with experimental data within 4% error. It is concluded that the drying of food material is affected by air temperature, the collector temperature, mode of heat transfer, and material characteristics such as dimension, and mass of the food sample.
