Web2 days ago · Drying is an essential unit operation in bioprocess engineering that involves the removal of moisture or water from a product. In bioprocessing, drying is a critical step because it helps to preserve the quality and stability of the product, prevent microbial growth, and enhance shelf-life. The following are some general methods of drying: • Application of hot air (convective or direct drying). Air heating increases the drying force for heat transfer and accelerates drying. It also reduces air relative humidity, further increasing the driving force for drying. In the falling rate period, as moisture content falls, the solids heat up and the higher temperatures spee…
