Quick Summary

Drying, also known as dehydration, is a material processing technique used to remove moisture from substances. This is crucial for preserving materials like food and wood, as high water content can lead to spoilage and degradation by microorganisms and enzymes.12

In food processing, dehydration extends shelf life and concentrates nutrients. Various methods are employed, including air drying, vacuum drying, and freeze-drying, each with specific impacts on nutrient retention and texture. For wood, drying is essential to prevent shrinkage, swelling, and microbial damage, preparing it for use in construction and manufacturing. Methods range from open-air drying to controlled kiln drying. In textiles, drying removes excess moisture after processing stages like bleaching, using heated dryers to achieve desired dryness without damaging the fabric's texture.123
