Drying technology is a research area focused on the development of efficient and effective methods for removing moisture from various materials, such as food products, pharmaceuticals, chemicals, and agricultural products. This technology involves the use of various drying techniques, including air drying, freeze drying, spray drying, and vacuum drying, to reduce the moisture content of materials and extend their shelf life. Researchers in this field work to improve the drying process by optimizing drying parameters, enhancing energy efficiency, and minimizing product degradation. The goals of drying technology research include increasing the quality and stability of dried products, reducing processing time and energy consumption, and ensuring the safety of the final product.
