Drying topics include: Drying theory basics, moisture content determination methods, psychrometry, equilibrium moisture content, drying equipments, drying rate, sun and freeze drying. Drying is a food processing method that dehydrates food by evaporating free water with heat. It's one of the oldest methods of food preservation. Drying removes moisture from meat products so that microorganisms cannot grow. Dry sausages, freeze-dried meats, and jerky products are all examples of dried meats that can be stored at room temperature without rapid spoilage. Here are some ways to dry food: Air...

Drying is a food processing method that dehydrates food by evaporating free water with heat. It's one of the oldest methods of food preservation. Drying removes moisture from meat products so that microorganisms cannot grow. Dry sausages, freeze-dried meats, and jerky products are all examples of dried meats that can be stored at room temperature without rapid spoilage. Here are some ways to dry food: Air drying: This method uses natural air movement and ventilation to dry produce. It's suitable for small-scale operations and is commonly used for herbs and certain fruits and vegetables. Sun drying: This method uses sun or solar heat to evaporate water from products, assisted by movement of surrounding air. It demands a rainless season of bright sunshine and temperatures above 98° F. Oven drying: This method exposes materials or substances to high temperatures in an oven to remove moisture. To ensure even drying, rotate trays top to bottom halfway through drying time. Set the oven at its lowest temperature setting, but not below 140–150°F. A gas oven should have a vent that will allow moisture to escape. Freeze drying: Also known as lyophilization, this process removes water in the form of ice under low pressure by sublimation. It's usually used for drying heat sensitive food material by freezing the material and then reducing the surrounding pressure. Vacuum drying: This method takes advantage of the fact that evaporation of water occurs more readily at lower pressures than at higher ones. Other methods of drying food include dehydrators and microwave drying. Show less
