MICROWAVE PROCESSING OF ANIMAL FEED: A BRIEF REVIEW

Abstract

Microwave frequencies occupy the portion of the electromagnetic spectrum from 300 MHz to 300 GHz. Microwave heating involves the simultaneous and rapid diffusion of heat and moisture through a material as a result of interactions between electromagnetic fields and polar molecules in the material. Microwave treatment of animal fodder and grains achieves many beneficial outcomes. It can be used for efficient drying and moisture leveling prior to long-term fodder storage. Localized steam explosions within the cell structures during microwave treatment also significantly increase the moisture permeability of biomass, decrease its mechanical strength, and increase its digestibility. Microwave tre..
